Answer:

Problem 1: 12.56

Problem 2: 20.94

Step-by-step explanation:

Problem One (left)

Givens

r = 16

Theta = 45 degrees

pi = 3.14

Formula

Length = theta/360 * pi * 2*r

Substitute ans Solution

Length = 45/360 * pi *2*16      Substitute

Length = 0.125 * 3.14 * 32        Combine 45 / 360 = 0.125

Length = 12.56 <<<< Answer

Problem Two

Theta = 120

pi = 3.14

r = 10

Substitute and Solution

Length = 120/360  * pi * 2*r

Length = 1/3 * 3.14 * 2 * 10

Length = 1/3 * 3.14 *20

Length = 20.94

zvonat [6]

Answer:

$15.00

Step-by-step explanation:

Suppose 1 rose bush costs r dollars,

Suppose 1 geranium costs g dollars.

Here are 2 equations:

1)6r+14g=146

3r+7g=73

2)r+7g=57

r=57-7g

Put 2) in 1)

3(57-7g)+7g=73

171-21g+7g=73

98=14g

g=7

r=8

7+8=$15.00

If the original function () = 22 − 1 is shifted to the left 3 units to make the
Rom4ik [11]

A horizontal translation is expressed by transforming

f(x)\mapsto f(x+k)

If k is positive, the function is translated to the left. If k is negative, the function is translated to the right.

So, a 3-units left shift is given by k=3. So you have

f(x)=2x^2-1 \implies f(x+3)=2(x+3)^2-1
