Answer:

calculate the areas of the perimeter. A=5m x 7m =35m^2

Step-by-step explanation:

the area of the perimeter is 35 squared or 35 square meters.

measure the base and height of the square use the formula a= 1/2(bxh)

to find the area of the square. a square with the height of 7m and the base as 3m has an area of A=1/2(7m x3m) =1/2(21m^2)=10.5m^2

the area of (A) of the square is 10.5 meters squared or 10.5 square meters.

Answer:

volume = 7 * 4 * 24 = 672 m 3

Step-by-step explanation:

a^2 = 25^2 - 7^2 = 576

-> a = 24

volume = 7 * 4 * 24 = 672 m 3

Evaluate the inverse trigonometric function Sin^-1(-1). Give answers in both radians and degrees.
grin007 [14]

Answer:

B) Sin^-1(-1) = 3pi/2 or 270°

D) Sin^-1(-1) = -pi/2 or -90°

Step-by-step explanation:

Sine function:

The sine function is -1 at 270º(-90º), which is 3pi/2 = -pi/2.

Inverse sine:

The input of the inverse sine function is a value, and the output are the angles which have the sine equal to the input.

Sin^-1(-1)

Angles for which the sine are -1, that is 3pi/2 or 270° and -pi/2 or -90°. Thus, options B and D are correct.

If m∠2=39 and m∠3=30, what is m∠1?
satela [25.4K]

Answer:

The answer would be A.) 111

Step-by-step explanation:

The angles of any triangle must add up to 180. So you subtract ∠1 and ∠2 from 180 and you will get the 3rd angle.

B is the midpoint of AC and E' is the midpoint of BD. If A(-9,-4), C(-1, 6), and E(-4,-3), find the coordinates of D.
Ipatiy [6.2K]
The coordinates for D are (-4, -7)

First we must locate point B as it is vital to finding the midpoint of BD. To do this, we take the average of the endpoints AC since B is its midpoint. 

x values = -9 + 1 = -8
Then divide by 2 for the average -8/2 = -4

y values = -4 + 6 = 2
Then divide by 2 for the average 2/2 = 1

Therefore B must be (-4, 1)

Now we know the values of E must be the average of B and D. So we can write equations for each coordinate since we know they are averages. 

x - values = (Bx + Dx)/2 = Ex
(-4 + Dx)/2 = -4 ---> multiply both sides by 2
-4 + Dx = -8 ---> add -4 to both sides
Dx = -4

y - values = (By + Dy)/2 = Ey
(1 + Dy)/2 = -3 ---> multiply both sides by 2
1 + Dy = -6 ---> subtract 1 from both side
Dy = -7

So the coordinates for D must be (-4, -7)
