Answer:

$125i$

Step-by-step explanation:

We want to find

$5^3i^9$

This can be rewritten as;

$5^3i^8\times i$

$5^3(i^2)^4\times i$

Recall that; $i^2=-1$

$5^3(-1)^4\times i$

We evaluate now to obtain;

$125(1)\times i=125i$

X 0 y was 30

at x 12 y is about 55

12-0 = 12

55-30 = 25

25/12 = 2.08 inches per year average

so answer should be D

2p+6a=$14
3p+9a=$21

3p+9a=21
Subtract 9a
3p=21-9a
divide all by 3
p=7-3a
plug it into start equations

2p+6a=14
2(7-3a)+6a=14
14-6a....+6a=14

this zeroes out...

If a coin is tossed twice what is the probability of getting two heads

Degger [83]

25% because the first FLIP, it was a fifty-fifty chance. FLIP again and the chances are divided by two since you can only get 2 things, either heads or tails.

How are the solutions to the inequality -3x>18 different from the solutions to -3x>18 ?

Novay_Z [31]

Answer:

x < -6

Step-by-step explanation:

-3x > 18

Divide both sides by -3

-3x/-3 < 18/-3

Note : in inequalities when both sides are divided by negative or minus, the inequality sign changes.

Therefore

x < -6

There's no difference as the equations are the same

what is the value of a for the exponential function in the graph represented in the form of f(x)=a(b^x)? Zoom in the photo bcz i

nekit [7.7K]

Answer:

$a = 3$

Step-by-step explanation:

To determine the value of $a$ , we want $b^x$ to be 1, so that $f(x) = a \times 1$ . Notice that if $x = 0$ , then $f(0) = a \times (b^0) = a$ , so the value of $a$ is simply $f(0)$ . From the graph, it appears that $f(0) = 3$ , so therefore $a = 3$ .
