The function f(x) is represented by this table of values. x f(x) -5 35 -4 24 -3 15 -2 8 -1 3 0 0 1 -1 Match the average rates of

Paul [167]

The given data is shown in the table below.

x: -5 -4 -3 -2 -1 0 1
f(x): 35 24 15 8 3 0 -1

A graph of the data is shown below.

Calculate rates of change, r.
Interval: [-5, -1]
r = (35 - 3)/(-5+1) = -8 (tile -8)

Interval: [-4, -1]:
r = (24 - 3)/(-4 + 1) = -7 (tile -7)

Interval: [-3, 1]:
r = (15 + 1)/(-3 - 1) = -4 (tile - 4)

Interval: [-2, 1]
r = (8 + 1)/(-2 - 1) = -3 (tile -3)

Answer:

Tile Interval
----- ----------
-3 [-2, 1]
-4 [-3, 1]
-7 [-4, -1]
-8 [-5, -1]

Let's Apply Solve for the surface area of the following figures. <br><br>please i need this rn

Dafna1 [17]

Answer:

Step-by-step explanation:

1) Surface area of a square = s*s = 12*12 = 144 in

2) Surface area of a Cone = A=πr(r+h2+r2) = 3.142*4(4+22*2+4*2) = 351.904 cm^2

3) S.A of a Cylinder =2πrh+2πr2 = 2*3.142*2*14 + 2*3.142*2*2 = 201.088 m^2

4) S.A of a square Pyramid = a^2 + 2a squareroot (a^2/4 + h^2) = 516.5m^2

5) S.A of a Sphere = 4*pie*r^2 = 4* 3.142*15^2 = 2827.8mm^2

Please help. there is a picture below

OleMash [197]

Two triangles are similar if and only if all corresponding angles are equal (congruence), even if the corresponding sides are equal or not, therefore the answer is true because ΔJKL and ΔRST are similar and the statement above demands that "it must be", namely, this is a sufficient condition.
