Answer:

612 m^2.

Step-by-step explanation:

Area = area of 3 rectangles + area of 2 triangles

= 15 * 14 + 9 * 14 + 12 *14 + 1/2 * 9 * 12 + 1/2 * 9 * 12

= 210 + 126 + 168 + 54 + 54

= 612 m^2.

1. Given the following relation, determine the inverse relation.
gayaneshka [121]

Answer:

1. a

2. f^{-1} (x)=\frac{x}{2} +2

Step-by-step explanation:

1. Since there is one value of y for every value of x in (−1,0),(−4,5),(3,2),(−3,5), this relation is a function.

2. To find the inverse, interchange the variables and solve for y.

f^{-1} (x)=\frac{x}{2} +2

Pls help this is probably super easy but not for me
san4es73 [151]

Answer:

A.    29 feet

Step-by-step explanation:

Use cos to find the hypotenuse

cos  = adj/hp

0.64 = 20/hyp

hyp = 20/0.64

hyp = 31.25

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

Use Pythagorean Theorem to find the height of tree above eyes

a² + b² = c²

a² + 20² = 31.25²

a² = 31.25² - 20²

a² = 576.5625

a = 24  (to the nearest foot)

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

Finally add in the eye height

h = 24 + 5

h = 29 feet
