Answer:

a < -1

Step-by-step explanation:

Okay, so we are given this equation:

t(x) = ax^5 + 2

Lets plug in -2 as x and see what happens.. t(x) can be 66..

a * (-2)^{5}  + 2 = 66

-32a + 2 = 66

-32a = 64

a = -2

A is less than -1,

a < -1

Harlamova29_29 [7]

Answer:

$11,170

Step-by-step explanation:

First you convert the percentage to decimal form out of 100 (which you divide)

3.9%/100 =  0.039

A = P(1 + rt)

A = 10000(1 + 0.039 * 3)     ( * = multiplication)

I = $11,170 - 10,000 = $1,170

Which you should get $1,170.00 or $1,170 (which is pretty much the same thing)

Hope this helps!

gavmur [86]

Answer:

Plane 1:  rate = 245 mph

Plane 2:  rate = 98 mph

Step-by-step explanation:

Plane 2:  Let r = rate

                    d = 5r

Plane 1:    2.5r = rate

                    d = 5(2.5r)

5(2.5r) - 5r = 735

12.5r - 5r = 735

7.5r = 735

r = 98
