Answer: 6
Step-by-step explanation:
6/7 divided by 1/7 would be the same as 6 times 7 over 7 times 1 because to divide fractions you multiply by the reciprocal etcetera. Therefore, the fraction would become 42/7 which, if simplified, gives you 6/1, and thus the answer of one. Hope this helps!

Answer:
1. a, b, c - represent growth
2. b, c, d - represent decay
Step-by-step explanation:
If increasing x results in a larger value, the function represents growth. If it results in a smaller value, the function represents decay.

To answer these questions, you can look at the base and the exponent. When we say "exponent" here, we mean <em>the coefficient of the exponent variable</em>. There are four possibilities:
growth:
- exponent positive, base > 1
- exponent negative, base < 1
decay:
- exponent positive, base < 1
- exponent negative, base > 1

<u>Growth questions</u>:
1.77^x -- growth
1.5^(x/2) -- growth
0.5^(-x) -- growth (= 2^x)
e^(-t) -- decay (e ≈ 2.718)
<u>Decay questions</u>:
1.7^x -- growth
1.7^(-2x) -- decay
(1/3)^x -- decay (= 3^(-x))
2^(-x) -- decay
Well 7x10^-5 would mean you moved the decimal 5 Times because the power at the end of 10 is how many times the decimal is moved till it’s a number greater or equal to 1. So the scientific notation of that is: 0.00003
The -5 means that it was moved to the right. Positive always means left. Negative is always right.
Answer:
<x = 53 degrees
Step-by-step explanation:
<Q = 62 degrees (alternate angle)
<PRQ = 180-115 (Angles on a straight line add up to 180 degrees)
<PRQ = 65 degrees
<u><em>Now, Finding <x</em></u>
To find <x, we'll simply subtract 180 from rest of the triangles interior angles because the interior angles of a triangle add up to 180 degrees
=> <x = 180-65-62
=> <x = 53 degrees
