5+4=9
6+7=13
8+9=17
9+13=22
17+22=39
=39
Answer:
You write the non-zero digits, placing a decimal after the first non-zero digit. Then, you count the number of digits you need to move the beginning decimal to get to where your decimal is now. If you move the decimal to the left, then your power is positive.
Step-by-step explanation:
so for example, .005 would be 5x10^-2 and 500 would be 5x10^2
A = 289
That's the side s squared,
s² = 289
s = 17
In a square the perimeter is the sum of four equal sides
p = s + s + s + s = 4s = 4(17) = 68
Answer: 68 feet
Answer:
A.
Step-by-step explanation:
We have x in exponent, so it is an exponential function.
Exponent is negative, so is is an exponential decay.
There are no solutuons listed (says which of the following). My answer below should be in the list to choose from.
7 - 4x ≥ 35
subtract 7 from both sides
-4x ≥ 28
divide both sides by -4 AND change the direction of the inequality sign because we're dividing by a negative
x ≤ -7
CHECK:
7 - 4x ≥ 35
7 - 4(-7) ≥ 35
7 + 28 ≥ 35
35 ≥ 35
ANSWER: x ≤ -7
Hope this helps! :)
