How to obtain the angle between two vectors?

The cosine of the angle between two vectors a and b is obtained according to the equation presented as follows:

[tex]\cos{\theta} = \frac{ab}{|a||b|}[/tex]

In which:

ab is the dot product of vectors a and b.|a| is the norm of vector a.|b| is the norm of vector b.

The dot product of the two vectors in this problem is given as follows:

190 x 128 - 160 x 121 = 4960.

The norm of each vector is given as follows:

|a| = sqrt(190² + 160²) = 248.4.|b| = sqrt(128² + 121²) = 176.1.

Hence the angle is obtained as follows:

cos(x) = 4960/(248.4 x 176.1)

cos(x) = 0.1134

x = arccos(0.1134)

x = 83º.

What is the linear function?

A linear function is defined as a function that has either one or two variables without exponents. It is a function that graphs to a straight line.

To determine the exponential function represented by the values in the table, we need to look for a function of form f(x) = abˣ that passes through the given points.

Let's plug in the x and f(x) values from the table into the general formula:

When x = -2, f(x) = 16 gives us 16 = ab⁻²

When x = -1, f(x) = 8 gives us 8 = ab⁻¹

When x = 0, f(x) = 4 gives us 4 = ab⁰

When x = 1, f(x) = 2 gives us 2 = ab¹

When x = 2, f(x) = 1 gives us 1 = ab²

We can rewrite the equations as:

16 = a/b²

8 = a/b

4 = a

2 = ab

1 = ab²

We can solve for a and b by using a system of equations:

From the equation 4 = a, we get a = 4.

Substituting a = 4 into the equation 2 = ab, we get b = 2/a = 1/2.

Therefore, the exponential function represented by the values in the table is:

f(x) = 4(1/2)ˣ

Hence, the answer is an option (D) f(x) = One-half (one-half) superscript x.

O1049.15
O1409.15
O4145.24
O5000.0

Answers

The total amount of interest earned on the account is $1049.15.

What is simple and compound interest?

Simple interest is interest that is just based on the principal. It does not account for any interest accrued in prior periods and is determined as a percentage of the principal. If your principal is $1,000 and your yearly interest rate is 5%, for instance, you would make $50 in simple interest after a year ($1,000 0.05).

Contrarily, compound interest is calculated on the principal amount in addition to any prior quarters' interest. This means that interest is calculated on the new amount after the principal and interest earned during each period have been added.

The compound interest is given by the formula:

[tex]A = P(1 + r/n)^{(nt)}[/tex]

Rearranging for P we have:

[tex]P = A / (1 + r/n)^{(nt)}[/tex]

Substituting the value of r = 3.2%, n = 2 and t = 6 we have:

[tex]P = 6049.15 / (1 + 0.032/2)^{(2*6)}[/tex]

P = 5000

Here, P is the initial balance.

Now, for interest we have:

I = A - P

Substituting the values:

I = $6049.15 - $5000

I = $1049.15

Hence, the total amount of interest earned on the account is $1049.15.

An image of a rectangular prism 4 ft. in length, 2 ft. in width, and 3 ft. in height is shown. Mandy is buying fish for her fish tank shown above. If each fish needs 3 ft. 3 of water, how many fish can Mandy have in her tank? A. 4 fish B. 8 fish C. 12 fish D. 24 fish

Answers

Answer:

B. 8 fish

Step-by-step explanation:

Prism Formula = b × h (base × height)

b: 4 ft. ×2 ft.

h: 3 ft.

4 × 2 = 8 ft.

8 × 3 = 24 ft. of water.

Since 3 ft. of water is required for each fish, we will divide.

24 ÷ 3 = 8 fish.

Therefore, Mandy can fit 8 fish in her tank.

If the common ratio is 1.25, what is the percent change?
Include the percentage symbol with your answer.

Answers

With a common ratio of 1.25, the percent change is 25%.

This indicates a relative increase or decrease of 25% from the initial value.

The percent change is a measure of the relative change in a value expressed as a percentage.

To calculate the percent change with a common ratio of 1.25, we can use the formula:

Percent Change = (Common Ratio - 1) [tex]\times[/tex]  100.

Percent Change = (Common Ratio - 1) [tex]\times[/tex]  100.

In this case, the common ratio is 1.25.

Substituting this value into the formula, we have:

Percent Change = (1.25 - 1 )[tex]\times[/tex] 100

[tex]= 0.25 \times 100[/tex]

= 25%.

The percent change, in this case, is 25%.

To understand the meaning of this percent change, consider an initial value of 100.

If we increase this value by 25%, the new value would be 125. Conversely, if we decrease the initial value by 25%, the new value would be 75.

Therefore, a percent change of 25% indicates a relative increase or decrease of 25% from the initial value.

It is important to note that the percent change is a measure of relative change and does not take into account the magnitude of the values.

In this case, a common ratio of 1.25 signifies a 25% increase or decrease, regardless of the specific values involved.

What is the minimum amount of money Mateo will need to save every month to reach his goal of paying off the remaining tuition cost at the end of 12 months? < PREVIOUS 1 0² 3 04 5 06​

Answers

Mateo needs to save at least $408.33 every month to reach his goal of paying off the remaining tuition cost at the end of 12 months.

What is fixed expense and variable expense?

Rent or a car payment are examples of monthly costs that are fixed expenses. On the other hand, a variable expense is one that can vary from month to month, like food or entertainment. Variable expenses demand greater flexibility in budgeting because the cost can change, but fixed expenses are often easier to prepare for because the amount is constant.

Given that, cost of tuition fee is $9,600 for the first year.

Now, Mateo's parents will pay for one-third of the tuition thus:

1/3 x $9,600 = $3,200

From the saving the money used is $1500 thus the remining cost is:

$9,600 - $3,200 - $1,500 = $4,900

For 12 months in a year we have:

$4,900 / 12 = $408.33

Hence, Mateo needs to save at least $408.33 every month to reach his goal of paying off the remaining tuition cost at the end of 12 months.

one face of the three-dimensional figure has a surface area of 16/3 square centimeters.

What is surface area?

The area is the space occupied by a two-dimensional flat surface. It is expressed in square units. The surface area of a three-dimensional object is the area occupied by its outer surface. It's also expressed in square units.

Let A represent the area of one of the three-dimensional figure's faces.

The overall surface area of the figure, including the base, is 26 square centimeters, according to the problem description. The total area of the base and the three similar faces is 26 - 5 = 21 square centimeters.

Because the three faces are identical, the total area of the three faces is 3A. As a result, we can write:

3A + 5 = 21

Subtraction of 5 from both sides yields:

3A = 16

Answers

Therefore, the value of the car in 2018 was approximately $13,197.36. Rounded to two decimal places, this is $13,197.36.

What is decimal?

A decimal is a way of representing a number that is based on powers of ten. It is a number expressed in the base-ten system, which means that each digit in the number represents a power of 10. The decimal point separates the whole number part of the decimal from the fractional part of the decimal.

To model the depreciation of the car over time, we can use the formula:

f(t) = a(1 - r)^t

where:

After t years, f(t) is the car's worth.

a is the initial value of the car, which is $28,750.

r is the annual depreciation rate, which is 12% or 0.12 (expressed as a decimal).

t represents how long it has been since the car been acquired.

Substituting the given values, we get:

f(t) = 28,750(1 - 0.12)^t

To find the value of the car in 2018, we need to substitute t = 6 (since 2018 is 6 years after 2012) and evaluate the function:

f(6) = 28,750(1 - 0.12)^6

Simplifying,

f(6) = 28,750(0.88)^6

Evaluating using a calculator, we get:

f(6) ≈ 13,197.36

Therefore, the value of the car in 2018 was approximately $13,197.36. Rounded to two decimal places, this is $13,197.36.

Answer:

The vertex of a quadratic function of the form f(x) = ax^2 + bx + c is located at the point (-b/2a, f(-b/2a)).

In this case, the quadratic function is f(x) = -2x^2 + 12x - 9, so we can use the formula above to find the coordinates of the vertex:

x-coordinate of vertex = -b/2a = -12/(2*(-2)) = 3

To find the y-coordinate of the vertex, we can evaluate the function at x = 3:

f(3) = -2(3)^2 + 12(3) - 9 = 9

The radius of a circle is 1 foot. What is the length of a 90° arc?
90°
r=1ft
Give the exact answer in simplest form.

Answers

According to the given data the length of a [tex]90^{0}[/tex] arc is [tex]\pi /2[/tex] or approximately [tex]1.57[/tex] feet.

What is meant by length of arc?

In geometry, the length of an arc is the distance along the curved line that makes up the arc. It is a measure of the "length" of a portion of a circle's circumference, and it is usually expressed in the same units as the circle's radius.

According to the given information:

The length of a [tex]90^{0}[/tex] arc in a circle with radius [tex]1[/tex] foot can be calculated using the formula:

Length of arc = (angle/[tex]360[/tex]) x [tex]2\pi r[/tex]

where angle is the central angle of the arc in degrees, r is the radius of the circle, and [tex]\pi[/tex] is a mathematical constant approximately equal to [tex]3.14159[/tex].

Substituting the given values, we have:

Length of arc = ([tex]90/360[/tex]) x [tex]2\pi(1 ft)[/tex]

Length of arc = [tex](1/4)[/tex] x [tex]2\pi ft[/tex]

Length of arc = [tex]\pi /2 ft[/tex]

Therefore, the length of the [tex]90^{0}[/tex] arc is [tex]\pi /2 feet[/tex] or approximately [tex]1.57 feet[/tex]

What is arc of circle?

In geometry, an arc of a circle is a portion of the circle's circumference. It is defined by two endpoints and all points along the circle between those endpoints. The measure of an arc is typically given in degrees or radians and can be used to calculate various properties of the circle, such as its length, area, and sector angles.

The formula for the length of an arc is:

L = (θ/360) × 2πr

where L is the length of the arc, θ is the central angle of the arc in degrees, and r is the radius of the circle.

In this case, θ = 90° and r = 1 ft, so we have:

L = (90/360) × 2π(1) = (1/4) × π = π/4

Therefore, the length of the 90° arc is π/4 feet or approximately 0.785 feet (rounded to 3 decimal places).

Answers

On solving the query we can say that The slant height, along with the function cone's height and radius, makes a right triangle as it measures from the apex to a certain point on the circular base.

what is function?

Mathematics is concerned with numbers and their variations, equations and related structures, shapes and their places, and possible placements for them. The relationship between a collection of inputs, each of which has an associated output, is referred to as a "function". An relationship between inputs and outputs, where each input yields a single, distinct output, is called a function. Each function has a domain and a codomain, often known as a scope. The letter f is frequently used to represent functions (x). X is the input. The four main types of functions that are offered are on functions, one-to-one functions, many-to-one functions, within functions, and on functions.

You are informed that the cone in this scenario has a volume of 4.5 cubic inches. Using the aforementioned calculation, you can determine the radius if you know the cone's height.

Alternately, you may use the Pythagorean theorem to calculate for the radius if you know the cone's slant height. The slant height, along with the cone's height and radius, makes a right triangle as it measures from the apex to a certain point on the circular base.

Given the circle below with secants JKL and NML, find the length of JK. Round to the nearest tenth if necessary.

Answers

The length of JK is 42 units, which can be calculated using the theorem that states JK × JL = ML × JN, with the given lengths of KL, LM, and MN.

What is length?

Length is a measurement of how long or extended an object or distance is, typically measured in units such as meters, centimeters, feet, or inches.

What is Theorem?

A theorem is a statement or proposition that has been proven to be true through deductive reasoning or a mathematical proof, and is often used as a basis for further reasoning and conclusions.

According to the given information:

To find the length of JK, we can use the theorem which states that the product of the lengths of the segments of a secant is equal. In other words, JK × JL = ML × JN. We are given the lengths of KL, LM, and MN, and we know that KL + LM + MN = JL + JN.

We can use this information to solve for JK. First, we need to find JL and JN. We can do this by subtracting KL and MN from LM to get JL = LM - KL and JN = LM - MN. Substituting these values into the equation JK x (LM - KL) = KL × (LM - MN), we can solve for JK.

JK = (KL × (LM - MN)) / (LM - KL) = (14 × (17 - 14)) / (17 - 14) = 14 × 3 = 42.

Therefore, the length of JK is 42.
