Select the correct answer. Each statement describes a transformation of the graph of
Sever21 [200]

Answer:

The correct answer is d.

Step-by-step explanation:

Let's solve each answer and see which one matches.

Note that in each case, you simply add or subtract from x inside the radical to move left or right respectively.  Similarly, just add or subtract to the full expression to move up or down respectively. Doing so we get:

a) f(x) = \sqrt[3]{x + 7} + 3

b)f(x) = \sqrt[3]{x - 3} - 7

c)f(x) = \sqrt[3]{x - 3} + 7

d)f(x) = \sqrt[3]{x - 7} + 3

So d is the correct answer.

Step-by-step explanation:

(if 500 is 80%, divide 1500 by 4 to get 20%)

1500 divided by 4 is 375

375 plus 1500 is 1875

the local hardware store wants to increase their inventory. Last year 15 electric screwdrivers cost them 300.how much would 45 s
Harman [31]
One way of doing this is to write the equation of ratios (15 screwdrivers / 45 screwdrivers) = ($300 / x).    Solve this equation for x.  To do this, you might try multiplying both sides of this equation by x to eliminate fractions.

Another way is to obtain the unit cost of each screwdriver and then multiply the result by 45 screwdrivers.

I have some geometric sequence questions, will give 5 points for every answer and will give Brainliest!
kherson [118]

Answer:

Step-by-step explanation:

1) since the sixth term is 3 and the fifth term 24, the common ratio would be 3/24 = 1/8

The formula for finding the nth term of a geometric sequence is

Tn = ar^(n - 1)

If t6 = 3,r = 1/8, then

3 = a × 1/8^(6 - 1) = a × (1/8)^5

a = 3/(0.125)^5 = 98304

The first term is 98304.

Second term is 98304 × 1/8 = 12288

Third term is 12288 × 1/8 = 1536

Third term is 1536 × 1/8 = 192

2) t1 = 4

t2 = - 3t(2- 1) = - 3t1 = - 3 × 4 = - 12

t3 = - 3t(3- 1) = - 3t2 = - 3 × - 12 = 36

t4 = - 3t(4- 1) = - 3t3 = - 3 × 36 = - 108

3) let the numbers be t2,t3 and t4

The sequence becomes

1/2, t2,t3, t4,8

The formula for finding the nth term of a geometric sequence is

Tn = ar^(n - 1)

8 = 1/2 × r^(5 - 1)

8 = 1/2 × r^4

16 = r^4

2^4 = r^4

r = 2

t2 = 1/2 × 2 = 1

t3 = 1 × 2 = 2

t4 = 2 × 2 = 4
