Answer:

Range: (-∞, 0]

General Formulas and Concepts:

Algebra I

Range is the set of y-values that are outputted by function f(x)

Step-by-step explanation:

When we graph the equation, we should see that our y-values span from -∞ to 0. Since 0 is a closed dot, it is inclusive in the range:

(-∞, 0] or y ≤ 0

What is the approximate volume of the cone? Use 3.14 for π.

yawa3891 [41]

The formula for the volume of a cone is V= πr² (h/3).
V= 3.14 (12²) (8/3)
V= 3.14 (144) (2.6...)
V= 1205.76
V≈ 1206
So the answer is A.

F(1)=7, F(n)= -4* f(n-1)+15 Find the first four terms

Virty [35]

First four terms are 7, -13, 67, -253

Solution:

Given that,

$f(1) = 7$

The formula to find nth term is given as:

$f(n) = -4 \times f(n-1) + 15$

We can find the first four terms by substituting n = 2, 3, 4

First term:

f(1) = 7

Second term:

Substitute n = 2

$f(2) = -4 \times f(2-1) + 15\\\\f(2) = -4 \times f(1) + 15\\\\Substitute\ f(1) = 7\\\\f(2) = -4 \times 7 + 15\\\\Simplify\\\\f(2) = -28 + 15\\\\f(2) = -13$

Third term:

Substitute n = 3

$f(3) = -4 \times f(3-1) + 15\\\\f(3) = -4 \times f(2) + 15\\\\Substitute\ f(2) = -13\\\\f(3) = -4 \times -13 + 15\\\\Simplify\\\\f(3) = 52+15\\\\f(3) = 67$

Fourth term:

Substitute n = 4

$f(4) = -4 \times f(4-1) + 15\\\\f(4) = -4 \times f(3) + 15\\\\Substitute\ f(3) = 67\\\\f(4) = -4 \times 67 + 15\\\\Simplify\\\\f(4) = -268+15\\\\f(4) = -253$

Thus first four terms are 7, -13, 67, -253

A 8-kg load stretches an elastic belt 0.02 m. How much will a 12-kg load stretch the belt?

vazorg [7]

Answer:

A 12-kg load stretches an elastic the belt 0.03m

Step-by-step explanation:

we know A 8-kg load stretches an elastic belt 0.02 m.

=> 0.02 / 8 = 0.0025

so A 1-kg load can stretch an elastic belt 0.02 m.

=> 12 * 0.0025 = 0.03 m

A 12-kg load stretches an elastic the belt 0.03m
