<u>Answer:</u>

The correct answer option is -439.

<u>Step-by-step explanation:</u>

We are given the following two functions and we are to find the value of ( s o t ) ( -7 ):

s ( x ) = 2 - x ^ 2 and t ( x ) = 3

(s o t)(x)=s(t(x))

(s o t)(-7)=s(t(-7))

x=-7 → t(-7)=3(-7) → t(-7)=-21

(s o t)(-7)=s(t(-7))=s(-21)

x=-21 → s(-21)=2-(-21)^2=2-441 → s(-21)=-439

(s o t)(-7)=s(t(-7))=s(-21)=-439

MATHH!!! find the surface area of the composite figure. Please answer correctly &amp; tell me how you got your answer
snow_lady [41]

The total area of the given composite figure is; 84.8 ft²

<h3>How to find the area of a composite figure?</h3>

We are given;

Area of triangle = 5.6 ft²

Thus, area of 2 triangles = 2 * 5.6 = 11.2 ft²

Area of rectangles = 2(3.6 * 2) + 2(2 * 4) + 3(4 * 3.6)

Area of rectangles = 14.4 + 16 + 43.2

Area of rectangles = 73.6 ft²

Total Area of composite figure = 73.6 ft² + 11.2 ft²

Total Area of composite figure = 84.8 ft²

Can someone help please ? Thanks I’m advance
Pani-rosa [81]

Answer:

f(-3) = 16

Step-by-step explanation:

Given:

f(x) = 2x² + x + 1

Required:

f(-3)

Solution:

Substitute x = -3 into f(x) = 2x² + x + 1

f(-3) = 2(-3)² + (-3) + 1

f(-3) = 2*9 - 3 + 1

f(-3) = 18 - 3 + 1

f(-3) = 16
