Answer:

B. 73.5

Step-by-step explanation:

Using Excel (you can use similar software or a scientific calculator) we get the figure attached. After adding the trend line, we get that the equation that best fits the data is:

y = 0.0034*e^(0.7129*x)

Replacing with x = 14 we get:

y = 0.0034*e^(0.7129*14)

y = 73.5

Find the area of the triangle.

Vsevolod [243]

Answer:

20 m²

Step-by-step explanation:

Formula (Area of triangle):

$\text{A (Triangle)} = \dfrac{1}{2} \times \text{Base} \times \text{Height}$

From the triangle, we can see that the base of the triangle is "7 + 3" m and the height of the triangle is "4" m.

$\implies \text{A (Triangle)} = \dfrac{1}{2} \times (7 + 3) \times (4)$

Simplify the right-hand-side as needed to evaluate the area.

$\implies \text{A (Triangle)} = \dfrac{1}{2} \times (10) \times (4)$

$\implies \text{A (Triangle)} = \dfrac{40}{2} = 20 \ \text{m}^{2}$

Therefore, the area of the provided triangle is 20 m².

DONT IGNORE PLZ HELP ME!!

aleksklad [387]

A = base side=3

b= base side=5

c = base side=3

h= height=7-4=3

l= lenght=6

w= width=5

h= height=4

V= 1/4h√(-a⁴+2(ab)²+2(ac)²-b⁴+2(bc)²-c⁴) + l w h

V=12.44+ 120=132.44 unit³
