Answer:

3rd term: 24

10th term: 220

Step-by-step explanation:

<em>For the 3rd term</em>

2*3 + 2*(3^2) = 6 + 2*9 = 6 + 18 = 24

<em>For the 10th term</em>

2*10 + 2*(10^2) = 20 + 2*100 = 20 + 200 = 220

Is the expression 2 • 4 ^ x equal to the expression 8 ^ x ? Explain your answer

kkurt [141]

Answer:

It depends on the value of x

Step-by-step explanation:

If x=1, then yes

Exponents come before multiplication, so even if 2*4=8, 2*4^2 is not equal to 8.

Ex:

2*4^2=32

8^2=64

What is the distance between the points (-12, 11) and (-18, 17), to the<br> nearest tenth? *

Basile [38]

Answer:

8.5 units

Step-by-step explanation:

The distance between two points is given by

$d=\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}$

Taking points (-12, 11) and (-18, 17) as the first and second points respectively then

$d=\sqrt{(-18--12)^{2}+(17-11)^{2}}$

$d=\sqrt {36+36}$

d=8.48528137423857 units

Rounded off to nearest tenths

d=8.5 units
