Answer:

1)  θ = 130°

2)  θ = 310°

Step-by-step explanation:

We want to find a value of θ such that:

sin(θ) = sin(50°)

We know that sin(90°) = 1

We will have a symmetry around 90°.

Then if we define a constant k

sin(90° + k) = sin(90° - k)

we can define k such that:

90° - k = 50°

90° - 50° = k

40° = k

Then:

sin(90° + 40°) = sin(90° - 40°)

sin(130°) = sin(50°)

then θ = 130°

Now we want to find:

cos(θ) = cos(50°)

We know that cos(0°) = 1

Then we have symmetry around 0°

With the same reasoning than before, we can write:

cos( 0° + k) = cos(0° - k)

We can define:

0° + k = 50°

k = 50°

Then:

cos(50°) = cos(-50°)

But we want  0° < θ < 360°

Knowing that the peridisity of the trigonometric functions is of 360° then:

cos(50°) = cos(-50°) = cos( - 50° + 360°)

cos(50°) = cos(310°)

in this case θ = 310°

Step-by-step explanation:

The figure shown is a 30 - 60 - 90 degree special right triangle

The image below shows the properties of a 30 - 60 - 90 degree special right triangle

We are asked to find the longer leg (v)

The image tells us that the longer leg is equal to the shorter leg to the square root of 3

so v = 2 to the square of 3

Hence, the answer is the first one

Answer:

The sum of the first 47 terms of the series, 12, 16, 20, ... S₄₈ is 4,888

Step-by-step explanation:

The given series is;

12, 16, 20, ...,

Therefore, the first term of the series is, a = 12

The common difference of series is found as follows;

The difference between subsequent terms, 12 and 16 is  16 - 12 = 4

The difference between subsequent terms, 16, and 20 is  20 - 16 = 4

Therefore, the common difference, d = 4

The series is therefore an arithmetic projection, AP

The sum of the first 'n' terms of an AP, Sₙ, is given as follows;

[tex]S_n = \dfrac{n}{2} \cdot \left [2 \cdot a + (n - 1)\cdot d \right ][/tex]

(47/2)*(2*12+(47-1)*4)

The sum of the first 47 terms is therefore given as follows;

[tex]S_n = \dfrac{47}{2} \cdot \left [2 \times 12 + (47 - 1)\times 4 \right ] = 4,888[/tex]

The sum of the first 47 terms of the series, 12, 16, 20, ... S₄₈ = 4,888

Correct question is;

Factor out the GCF from the given polynomial. 10x³ + 16x² - 18x. (Type your answer in factored form.)​

Answer:

GCF = 5x² + 8x - 9

Step-by-step explanation:

The given polynomial is;

10x³ + 16x² - 18x

First thing is to inspect the coefficients and see the greatest number that all three can be divided by evenly without remainder.

The greatest number is 2.

Secondly let's inspect the variables to see what we can factor out.

They all contain x. Thus, x is a factor.

Thus, we will divide each term by 2x to obtain the GCF of the polynomial.

GCF = (10x³/2x) + (16x²/2x) - (18x/2x)

GCF = 5x² + 8x - 9

Answer:

0.53347

Step-by-step explanation:

We solve the above question using z score formula

z = (x-μ)/σ, where

x is the raw score = -0.084 °C

μ is the population mean = 0 °C

σ is the population standard deviation = 1°C

Z score =x - μ/σ

= -0.084 - 0/1

= -0.084

Probability value from Z-Table:

P(x<-0.084) = 0.46653

P(x>-0.084) = 1 - P(x<-0.084) = 0.53347

The probability of obtaining a reading greater than -0.084°C = P(x > -0.084) =

is 0.53347

Answer:

d. -1

Step-by-step explanation:

the slope is the rise over the run from one point to another.

i hope this helps :)

Each line is 1 unit.

Use the dots A and B

A is located at (-3,3)

B is located at (3,-3)

Slope is the change in y over the change in x

Slope = (-3 -3) / (3 - -3)

Slope = -6/6

Slope = -1

The answer is D -1

Answer:

I know I am almost a year late! lol But I just learned about it so I figured I could still help!

Step-by-step explanation:

The answer is 90.

Use this example/solution I was given to learn from:

Example:

Aaron's P.E. class is completing a unit on bowling. So every Friday afternoon for the last three weeks, they have bowled one game at a nearby bowling alley. His scores have been 121, 147, and 96. What would he have to bowl next time in order to have a mean score of 128?

Solution:

Let x represent Aaron's fourth and unknown score. To have a mean of 128, the sum of the four scores would have to be divided by 4. To get that sum by itself, multiply it by 4. You also have to multiply the desired mean of 128 by 4. So the sum of the four scores is equal to 128 times 4.

121 + 147 + 96 + x = 128 ∙ 4

• Substitute in the values of the four scores.

364 + x = 512

• Simplify.

364 - 364 + x = 512 - 364

• Subtract 364 from each side of the equation.

x = 148

• Simplify.

Aaron must score a 148 in order to have a mean score of 128.

Answer: C

Step-by-step explanation:

just took test

The interquartile range (IQR) for town A, 20°, is greater than the IQR for town B, 10°. The correct option is C.

The interquartile range (IQR) is a measure of the spread of the data's middle 50%. It is defined as the difference between the third and first quartiles (Q1). A larger IQR indicates that the data is spread out more.

Looking at the box plots, we can see that the IQR for town A is the distance between the lower and upper quartiles, which is approximately 30 - 20 = 10 degrees.

The IQR for town B is approximately 45 - 35 = 10 degrees.

So, the interquartile range (IQR) for town A, 20°, is greater than the IQR for town B, 10°.

Option A is incorrect because the IQR for town B exceeds 46o. Option B is incorrect because the box plots do not include the standard deviation. Option D is incorrect because the IQRs for the two towns differ.

Thus, the correct option is C.
