Answer:
10.8
Step-by-step explanation:
The answer is approx. 10.8 per hour.
If you want to round it up, it would be 11. I prefer you not to round though as this is Money. Money should have decimals included.
Divide 432 and 8. You should get 54. Then, divide by 5 and you will get 10.8. Divide by 5 because you still need the rate even though she worked 4 hours one day
Answer:
Step-by-step explanation:
<em>Use of properties</em>
- <em>log ab = log a + log b</em>
- <em>log a^b = b log a</em>
<u>Given expression</u>
<u>Simplifying</u>
- In 2x^2y^8 =
- ln 2 + ln x^2 + ln y^8 =
- ln 2 + 2 ln x + 8 ln y
Answer:
xy*(2x^2 + 7x^2 - y^2)
Step-by-step explanation:
You can get xy out of the expression since all have xy

<h3>f(3)=8</h3>
Answer:
Solution given:
f(x)=ax^4-bx^2+x+5 and
f(-3)=2
f(-3)=a(-3)^4-b(-3)^2+(-3)+5
2=81a-9b-3+5
2=81a-9b+2
subtracting both side by 2 and adding 9b
2-2+9b=81a-9b+9b+2-2
9b=81a
now
f(3)=a(3)^(4)-b(3)^(2)+3+5
f(3)=81a-9b+8
substituting value of 81a
f(3)=9b-9b+8
f(3)=8
