Answer:

10,000 square meters.

Step-by-step explanation:

First, let's split this shape into a rectangle and a triangle to make it easier.

Rectangle:

A = bh

We know the base is 120m and the height is 30m. So simply plug those into the equation.

A = (120)(30) = 3,600 square meters.

Triangle:

A = 1/2bh

Since we split the shape up, we have to calculate the triangles base and height.

To find the base, take the 120 and subtract the 40, giving us 80.

To find the height, take the 190 and subtract the 30, giving us 160.

Now take those numbers and plug them into the equation.

A = 1/2(80)(160) = 1/2(12,800) = 6,400 square meters.

Total:

Simply add the area of the rectangle to the area of the triangle to find the area of the entire shape.

A = 3,600 + 6,400 = 10,000 square meters.

The function f(x) = x2 is translated 7 units to the left and 3 units down to form the function g(x). Which represents g(x)?

nignag [31]

Answer:

B. g(x)=(x+7)^2-3

Step-by-step explanation:

Vertex form is F(x)= a(x-h)^2+k

a is the reflection

h and k are the vertex (x,y) = (h,k)

in this case there is no shrink or stretch (a)

if it is translating left or right it is "h". In this case it is translated left so its -7. However if you look at vertex form it is "x-h" so -7-7= +7

If it translating up or down it is "K". In this case it is translated down so its -3.

If it was translated up or right then its positive. If it was translated down or left its negative.

After you figure out what h and k are then you just plug it in. h=-7, k=-3

so the answer in vertex form is, g(x)=(x+7)^2-3

The area of a square can be found using the equation A=s^2, where A is the area and s is the measure of one side of the square.

MaRussiya [10]

A = 81 square in.

s = sqrt(A)

s = sqrt(81)

s = 9 in.

SOMEONE PLZ HELP ME WITH 10 and 8!!!!!

Allisa [31]

Answer:

10. $23.75^{o}$

8. $34.76^{o}$

Step-by-step explanation:

10. each step is 36, so i added it twice to get 72.

then add 16 twice = 32

this gives us two sides to our triangle.

We can now use tan since we know opp and adj

tan 32/72 = .44

arctan = 23.75

8. since we again know the opposite and adjacent sides to the angle e are trying to find we can use tan again.

tan 12.5/18 = .694

arctan= 34.76
