Answer:

3(x - 2)(2x + 3)

Step-by-step explanation:

6x² - 3x - 18 ← factor out GCF of 3 from each term

= 3(2x² - x - 6) ← factor the quadratic

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 6 = - 12 and sum = - 1

the factors are - 4 and + 3

use these factors to split the x- term

2x² - 4x + 3x - 6 ( factor the first/second and third/fourth terms )

= 2x(x - 2) + 3(x - 2) ← factor out (x - 2) from each term

= (x - 2)(2x + 3) ← in factored form

then

6x² - 3x - 18 = 3(x - 2)(2x + 3)

Answer:

x = 30 , y = 54

Step-by-step explanation:

the figure is a trapezium

each lower base angle is supplementary to the upper base angle on the same side, then

4x + y + 6 = 180 ( subtract 6 from both sides )

4x + y = 174 ( subtract 4x from both sides )

y = 174 - 4x → (1)

and

2x + 12 + 2y = 180 → (2)

substitute y = 174 - 4x into (2)

2x + 12 + 2(174 - 4x) = 180

2x + 12 + 348 - 8x = 180

- 6x + 360 = 180 ( subtract 360 from both sides )

- 6x = - 180 ( divide both sides by - 6 )

x = 30

substitute x = 30 into (1)

y = 174 - 4(30) = 174 - 120 = 54

thus x = 30 and y = 54

Number of balls ≈ [tex]1.03 * 10^9[/tex]

To calculate how many table tennis balls can fit into the coin building, we need to first figure out the volume of the building and the volume of the table tennis ball.

Then, we can divide the volume of the building by the volume of the ball to get an estimate of the number of balls that can fit inside.

The volume of a table tennis ball can be calculated using the formula for the volume of a sphere, which is:

V = (4/3)πr³

where V is the volume, π is pi (approximately 3.14), and r is the radius of the ball. In this case, the radius is given as 0.04m, so we can plug that in and get:

V = (4/3) x 3.14 x 0.04³

[tex]V =2.14 * 10^{-5} m^3[/tex]

Next, we need to find the volume of the coin building. The building has a width of 20m and a height of 110m, but we don't know its depth.

Let's assume that the building is a rectangular prism with a depth of 10m. Then, we can calculate its volume using the formula:

V = l x w x h

where l is the length, w is the width, and h is the height. Plugging in the given values, we get:

V = 20 x 10 x 110

V = 22000 m³

Now, we can divide the volume of the building by the volume of the ball to get an estimate of how many balls can fit inside:

Number of balls ≈ [tex]V_building / V_ball[/tex]

Number of balls ≈ 22000 / 2.14 x [tex]10^-5[/tex]

Number of balls ≈ [tex]1.03 * 10^9[/tex]

So we can estimate that approximately 1.03 billion table tennis balls can fit into the coin building.

As for the accuracy of this prediction, it's important to keep in mind that we made some assumptions and estimations in our calculations.

For example, we assumed that the building is a rectangular prism with a depth of 10m, which may not be completely accurate.

Additionally, we rounded some of our values and used approximations for pi.

Therefore, our estimate should be considered as a rough approximation rather than an exact calculation. Nonetheless, it gives us an idea of the scale of the building and how many objects it can hold.

The equation of the line that goes through the point (-2, -5) and is parallel to y = x + 2 is y = x - 3.

To find the equation of a line that goes through the point (-2, -5) and is parallel to y = x + 2, we will follow these steps:

1. Identify the slope of the given line.
2. Use the slope and the given point to find the equation of the new line.

Step 1: Identify the slope of the given line.
The equation of the given line is y = x + 2. This is in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. In this case, the slope (m) is 1, as it is the coefficient of x.

Step 2: Use the slope and the given point to find the equation of the new line.
Since the new line is parallel to the given line, it will have the same slope. Therefore, the slope of the new line is also 1.

Now, we will use the point-slope form of a linear equation, which is given by y - y1 = m(x - x1), where m is the slope, and (x1, y1) is the given point.

Plugging in the values, we have:
y - (-5) = 1(x - (-2))
y + 5 = 1(x + 2)

Now, let's rewrite the equation in slope-intercept form:
y + 5 = x + 2
y = x + 2 - 5
y = x - 3

So, the equation of the line that goes through the point (-2, -5) and is parallel to y = x + 2 is y = x - 3.

To get the derivative of the function f(x) = (5x - 5)(√x + 3) - 1/2, we'll first need to use the product rule and then simplify the expression. The product rule states that if you have a function g(x)h(x), its derivative is g'(x)h(x) + g(x)h'(x).

Let g(x) = 5x - 5 and h(x) = √x + 3.
Step 1: the derivatives of g(x) and h(x).
g'(x) = 5 (derivative of 5x - 5)
h'(x) = 1/(2√x) (derivative of √x + 3)
Step 2: Apply the product rule.
f'(x) = g'(x)h(x) + g(x)h'(x)
f'(x) = 5(√x + 3) + (5x - 5)(1/(2√x))

Answer:

Step-by-step explanation:

The total area of the coffee table (including the cherry border) is:

3 feet x 3 feet = 9 square feet

We know that the area of the cherry border is:

5 square feet

To find the width of the cherry border, we need to subtract the area of the glass top from the total area of the coffee table:

9 square feet - area of glass top = area of cherry border

The area of the glass top is:

(3 feet - 2x) x (3 feet - 2x)

where x is the width of the cherry border.

Since the glass top is square, we can set the two dimensions equal to each other:

(3 feet - 2x) = (3 feet - 2x)

Expanding the left-hand side, we get:

9 feet - 6x = 9 feet - 6x

Simplifying, we get:

0 = 0

This means that the width of the cherry border does not affect the area of the glass top. Therefore, we can set the area of the glass top equal to the total area of the coffee table minus the area of the cherry border:

(3 feet - 2x) x (3 feet - 2x) = 9 square feet - 5 square feet

Simplifying, we get:

(3 feet - 2x) x (3 feet - 2x) = 4 square feet

Expanding the left-hand side, we get:

9 feet^2 - 12 feet x + 4x^2 = 4 square feet

Subtracting 4 square feet from both sides, we get:

9 feet^2 - 12 feet x + 4x^2 - 4 square feet = 0

Simplifying, we get:

4x^2 - 12 feet x + 9 feet^2 - 4 square feet = 0

Using the quadratic formula, we get:

x = [12 feet ± sqrt((12 feet)^2 - 4(4)(9 feet^2 - 4 square feet))] / (2(4))

Simplifying, we get:

x = [12 feet ± sqrt(144 feet^2 - 4(4)(9 feet^2 - 4 square feet))] / 8

x = [12 feet ± sqrt(144 feet^2 - 144 feet^2 + 64 square feet)] / 8

x = [12 feet ±

The annual rate as a percent is approximately 4.86% per year.

To find the annual rate as a percent, we first need to understand the function that Robert is using. The function [tex]f(x) = 1000(1.0375)^x[/tex] represents the amount of money Robert earns each year based on his initial investment of $1000 and the interest rate of 3.75% (as represented by the value 1.0375, which is 1 + 0.0375).

To calculate the annual rate as a percent, we need to isolate the interest rate from the function. We can do this by using logarithms. Taking the logarithm of both sides of the equation, we get:

log(f(x)) = log(1000) + x*log(1.0375)

Now, we can solve for the interest rate (represented by the value of 1.0375) by dividing both sides of the equation by x and then taking the antilog of the result:

1.0375 = antilog[(log(f(x)) - log(1000))/x]

Using this formula, we can plug in any value for x (representing the number of years Robert has held his investment) and find the corresponding interest rate. For example, if Robert has held his investment for 5 years, we can calculate the interest rate as:

1.0375 = antilog[(log(f(5)) - log(1000))/5]

This gives us an interest rate of approximately 4.86% per year. So, to answer the original question, the annual rate as a percent is approximately 4.86%.

Sin theta = -5/sqrt(26) Is the correct option , To find the six trigonometric functions of theta, we need to first find the values of x and y on the terminal side of theta. From the given equation, 5x + y = 0 and x ≥ 0, we can solve for y in terms of x:

y = -5x

Since x ≥ 0, we know that (x, y) lies in the fourth quadrant. We can now use the Pythagorean theorem to find the length of the hypotenuse:

r =[tex]sqrt(x^2 + y^2) = sqrt(x^2 + (-5x)^2) = sqrt(26x^2)[/tex]

Now we can find the six trigonometric functions:

sin(theta) = y/r = [tex]-5x/sqrt(26x^2) = -5/sqrt(26)[/tex]

cos(theta) = x/r =[tex]x/sqrt(26x^2) = 1/sqrt(26)[/tex]

tan(theta) = y/x = -5x/x = -5

csc(theta) = r/y = [tex]sqrt(26x^2)/(-5x) = -sqrt(26)/5[/tex]

sec(theta) = r/x = sqrt(26x^2)/x = sqrt(26)/1 = sqrt(26)

cot(theta) = 1/tan(theta) = -1/5

Therefore, the exact values of the six trigonometric functions of theta are:

sin(theta) = -5/sqrt(26)

cos(theta) = 1/sqrt(26)

tan(theta) = -5

Let's use the given information to create an equation to model this situation. We know that Chad spends a total of $29.68 on the fruit salad, so we can start with;

2.15p + 3.75w + 4.48 = 29.68

This equation represents the total cost of the fruit salad, which includes the cost of the pineapples (2.15p), the cost of the watermelons (3.75w), and the cost of the bag of grapes (4.48).

To make this equation more specific to the problem of finding the number of pineapples and watermelons Chad can purchase, we need to use the variables p and w to represent those quantities. We can set up a second equation based on the information given about the total number of fruits;

p + w + 1 = T

Here, T represents the total number of fruits in the salad, and we add 1 to account for the bag of grapes.

Now we can use substitution to eliminate the variable T. Solving for T in terms of p and w;

T = p + w + 1

Substitute this expression for T into first equation;

2.15p + 3.75w + 4.48 = 29.68

Simplify;

The given table shows the prices for various amounts and kinds of bouquets sold by a florist. The prices depend on the number and type of flowers in the bouquet. The table shows prices for bouquets of 2 flowers with daisies, tulips, and roses.

The expression (23.90 - 2) - (60.80 – 2) represents that a bouquet of daisies is $18.45 more expensive than a bouquet of tulips. This is because the cost of a 2-flower bouquet of daisies is $23.90 and the cost of a 2-flower bouquet of tulips is $60.80, so the difference between them is $36.90.

However, we subtract 2 from each price to get the price of the actual flowers in the bouquet, which are the same for both daisies and tulips. Therefore, we get the difference of $18.45.

Similarly, the expression (60.80 - 2) - (23.90 + 2) represents that a bouquet of tulips is $18.45 more expensive than a bouquet of daisies. Here, we subtract the price of a 2-flower bouquet of daisies plus the cost of 2 flowers from the price of a 2-flower bouquet of tulips.

Again, the actual cost of flowers in both bouquets is the same, so we get the difference of $18.45.

The expressions 23.90 - 60.80 and 60.80 - 23.90 represent the price difference between bouquets of daisies and tulips, respectively. The former expression gives a negative result of $36.90, which means that a bouquet of tulips is $36.90 more expensive than a bouquet of daisies.
