Answer:

B

Step-by-step explanation:

pi / 2 is equal to 180°/2 which is 90°.

Cos (90°) = 0

if cos90 = 0 then what kind of graph will we have at 90° to the x axis ?

a graph passing through the origin. (0,0)

Explanation:

Draw a vertical line through the middle to split the figure into two rectangles.

The rectangle on the left is 21 ft by 7 ft. Its area is 21*7 = 147 sq ft.

The rectangle on the right is 24-7 = 17 ft by 21-10 = 11 ft. The area is 17*11 = 187 sq ft.

The combined area is therefore: 147+187 = 334 square feet

-------------

A different approach:

Draw a horizontal line through the middle to form two rectangles.

The rectangle on top is 10 ft by 7 ft with area of 10*7 = 70 sq ft.

The rectangle on the bottom is 24 ft by 12-10 = 11 ft, so its area is 24*11 = 264 sq ft.

Total area = 70+264 = 334 square feet

--------------

Yet another method:

Draw a horizontal line through the top most edge of the figure. Do the same for the right-most side of the figure. The two lines meet in the top right corner. This will form a rectangle that is 21 ft tall and 24 ft wide.

The area of this big new rectangle is 21*24 = 504 sq ft.

However, we don't want all of this area. We'll kick out the rectangular piece that is 10 ft tall by 24-7 = 17 ft across (in the upper right corner). The area we want to kick out is 10*17 = 170 sq ft.

The actual area we want is 504 - 170 = 334 square feet

There are probably other methods you could use to find the area of this figure.

1. Observe Problem

Use crossout to determine the answer

As we approach immediately, we notice that A is the answer

For the equation  cos(x) = sin(14°) where 0° < x < 90° the value of x is 76 degrees.

We have given,

For what value of x is,

cos(x) = sin(14°),

where 0° < x < 90°

1. Observe the problem

Use cross out to determine the answer.

[tex]cosx=sin(14^0)[/tex]

The value of the sin(14) degree is 0.2491

[tex]cosx=sin(14^0)\\\\\\cosx=0.24192\\\\\\x=cos^{-1}(0.24192)[/tex]

[tex]x=76.05^0[/tex]

x=76.05 degrees.

As we approach immediately, we notice that A is the answer.

Therefore,For cos(x) = sin(14°) value of x is 76 degrees.

Answer:

63.44 feet

Step-by-step explanation:

tan(68 degrees)= 85/y  

y tan (68 degrees)=85

y=85/tan(68 degrees) ( cross multiply)

y = 34.34 feet

tan (41 degrees)=85/x+y

(x+y)tan(41 degrees)=85

x+y=85/tan 41 degrees

x=85/tan(41 degrees) - y

x= 85/tan (41 degrees)-(34.34) (cross multiply)

Therefore, Travis stepped back 63.44 feet to gain a better view!

Output value (y) of the y = 1.157.exponetial functio9n when x = 3 is: (3, 1,250).

An exponential function is a type of function that has a constant that is raised to a given power. It is expressed as [tex]y = a^x[/tex].

Given the exponential function, [tex]y = 10 \times 5^x[/tex]

When x = 3, thus:

[tex]y = 10 \times 5^3\\\\y = 1,250[/tex]

Therefore, output value (y) of the y = 1.157.exponetial function when x = 3 is: (3, 1,250).

Answer:

x = 6 and x = -6

Step-by-step explanation:

x² = 36

to solve for 'x' we need to take its square root but must do the same to the other side:

x = [tex]\sqrt{36}[/tex]

square roots have both positive and negative roots:

6 x 6 = 36

(-6) x (-6) = 36

x = ±6

Answer:

x = 50°

Step-by-step explanation:

          A triangle has total interior of 180 degree .

x + 84° + 46° = 180°

x = 180° -46° -84°

x = 50°

In the given triangle, the value of x is determined to be 50°. In other words, The value of x in the triangle is 50°.

To find the value of x in a triangle with angles measuring 84°, 46°, and x°, follow these steps:

Step 1: Recall that the sum of the angles in a triangle is always 180 degrees.

Therefore, the sum of the three angles in the given triangle is:

[tex]84 + 46 + x = 180[/tex]

Step 2: Combine like terms and isolate x.

Start by subtracting 84 and 46 from both sides of the equation:

[tex]84 + 46 + x - 84 - 46 = 180 - 84 - 46[/tex]

[tex]x = 50^{\circ}[/tex]

Step 3: The value of x is 50. This means that the third angle in the triangle measures 50°.

By applying the fact that the sum of angles in a triangle is 180°, set up an equation and solve for x.

Answer: y = 0.4x

In fraction form, this is y = (2/5)x

================================================

Explanation:

For each row, divide the y over x values

We end up with the same thing each time.

Since y/x = 0.4, this rearranges to y = 0.4x

Alternatively, you can write the equation as y = (2/5)x because 2/5 = 0.4

Answer:

[tex]19\ 227\ 000\ m^{3}[/tex]

Step-by-step explanation:

The equation for volume of a rectangular prism is
[tex]V = \frac{hB}{3}[/tex]

[tex]B = lw[/tex]

V is volume

B is base

so if the base measures 522 multipled by 500

multiply length and width B = 522 • 500 = 261000

height is 221

V = [tex]\frac{hB}{3}[/tex]

Fill in variables V = [tex]\frac{221(251000)}{3}[/tex]

Multiply V = [tex]\frac{57681000}{3}[/tex]

Divide V = [tex]19\ 227\ 000\ m^{3}[/tex]
