Answer:
t = 12h
Step-by-step explanation:
t = total
h = hours
Answer:
D. (x+2)(-8x+70)
Step-by-step explanation:
-8x^2+54x+140
Factor out -2
-2(4x^2+27x+70)
Factor
-2(x+2)(4x-35)
Option D is the same answer if we multiply -2 in the second term
(x+2) (-8x+70)
Answer:
39.25
Step-by-step explanation:
diameter. is 1 therefore radius is 1/2
formula is πr²h
where
h is height=5
=3.14x½²x5
=3.925 for one paint
therefore for 10 paints, we have
=3.925x10
=39.25
Given :
A holiday meal cost 12.50 a person plus a delivery fee of $30 at we cater.
The same meal cost $15 a person with no fee at Good Eats.
To Find :
When does we cater become the better deal.
Solution :
Let , x is number of order .
Cost at cater , C = 12.5x + 30 .
Cost at Good Eats , G = 15x .
We need to find :
G > C

Therefore, after 12th order cater will be more value for money.
Hence, this is the required solution.
The simplification of 3log(x + 4) – 2log(x – 7) + 5log(x - 2) - log(x^2) is 
<u>Solution:</u>
Given, expression is 
We have to write in as single logarithm by simplifying it.
Now, take the given expression.

Rearranging the terms we get,







Hence, the simplified form
