Answer: Therefore the  length of the pole in  10.1 foot (approx) .

Step-by-step explanation:

To proof

As given

The pole casts a 12-foot shadow when the sun is at a 40° angle of elevation.

x represented the length of pole .

As shown in the diagram

By using the trignometric identity

tan40° = 0.839099631 ( approx )

Put in the above

x = 12 × 0.839099631

x = 10.1 foot (approx)

Therefore the  length of the pole in  10.1 foot (approx) .

The 90 gallons of water is in the fish tank if the fish tank has 240 quarts of water. Levi adds another 120 quarts to the tank.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, multiplication by a conversion factor.

We have a fish tank has 240 quarts of water.

Levi adds another, 1201 quarts to the tank.

Total water in the tank = 240 + 120 = 360 quartz

To convert quartz to gallon, divide by 4

Total water in the tank = 360/4 = 90 gallons

Thus, the 90 gallons of water is in the fish tank if the fish tank has 240 quarts of water. Levi adds another 120 quarts to the tank.

The circumference is 6.3 in

The circumference of the circle is given by the equation C = 6.3 inches

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the circumference of the circle be represented as C

Now , the equation will be

Let the radius of the circle be r = 1 inch

Now , circumference of circle = 2πr

Substituting the values in the equation , we get

The circumference of the circle C = 2 ( 3.14159 ) x 1

On simplifying the equation , we get

The circumference of the circle C = 6.3 inches

Hence , the circumference of the circle is 6.3 inches

The P(pass | Test A) is 31.81%, P(pass | Test B) is 29.87%, and P(pass | Test C) is 22.07%

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Part A:

Total number of students = 154

Total number of students passed the test = 49

The probability:

P(pass | Test A) = 49/154 = 31.81%

Part B:

Total number of students = 154

Total number of students passed the test = 46

The probability:

P(pass | Test B) = 46/154 = 29.87%

Similarly, for the probability:

P(pass | Test C) = 34/154 = 22.07%

Thus, the P(pass | Test A) is 31.81%, P(pass | Test B) is 29.87%, and P(pass | Test C) is 22.07%

y = - 3x

Step-by-step explanation:

an equation involving direct proportion has the form

y = kx ← k is the constant of proportion

the only equation in this form is

y = - 3x ( with k = - 3  )

Seeing as this is a right triangle, we would solve for the unknown angle using a trigonometric function.

Remember! SOH-CAH-TOA

Looking from the unknown angle, we are given the adjacent side and the hypotenuse. Therefore, we should use the cosine function.

cos(?) = 17 / 19

---To find the unknown angle measure, you will need to use the inverse cosine function. This function is generally found by using the "2nd" button on your calculator and then pressing the cosine button. It should look like one of the following options: "cos^-1" or "arccos".

Make sure your calculator is in degrees, not radians!

Answer:

n = 3

Step-by-step explanation:

Isosceles means that the left and right sides (non-parallel sides) are equal to each other and so the base angles are also equal to each other. Then you can make an equation with the 8n^2-11 set equal to the 2n^2+7.

see image.

To solve it you have to set everything equal to zero (get all terms on one side of the equation) FACTOR (you end up with the difference of two squares) and solve, using zero product property. See image.

have a wonderful day :))

Answer:

-4(6a + 11)

-Step-by-step explanation:

−24a − 44 if −4 is factored out than...

-4 times ____ = -24a

-4x = -24  → divided both sides by -4    

-4x / -4 = -24 / -4  → x = 6

-4 times     6     = -24a

-4 times ____ = -44

-4x = -44  → divided both sides by -4    

-4x / -4 = -44 / -4  → x = 11

-4 times     11     = -44

combine: -4 x 6a - 4 x 11

Answer:

C) <AFL

Step-by-step explanation:

The middle angle typically goes in the middle of the three letters. So, the naming should look like <FAL or <LAF. The letter A would have to remain in the middle for the naming to be correct.

Angles can be named in these following ways:

- By three capital letters (vertex (middle point) always in the middle)

- By one capital letter (typically the vertex)

- By a lowercase letter or number that is in the middle of the angle

Therefore, the incorrect naming would be C) <AFL, since the vertex isn't in the middle.

Considering that the square root of 49 is 7, and 52 > 49, Alejandro was not correct, as the correct integer is of 48.

The integer that has square root n is given by:

S(n) = n².

Hence the closest is given by:

C(n) = n² - 1.

In this problem, we have n = 7, hence:

C(7) = 7² - 1 = 48.

The value of s to the nearest whole number is 14. The correct option is the last option 14

From the question, we are to determine the value of s

Using the laws of cosines

a² = b² + c² -2bc Cos A

Then,

s² = 8² + 9² -2(8)(9) cos111°

s² = 64 + 81 - 144 cos111°

s² = 145 - (-51.605)

s² = 145 + 51.605

s² = √196.605

s = 14.0216

s ≅ 14

Hence, the value of s to the nearest whole number is 14. The correct option is the last option 14
