(x+1)(x-5)= 2^4=16
x^2 -4x -5 =16
x^2-4x-21=0
x= -3 or 7
but we would choose 7 as the answer as -3 gives negative value at (x+1) and we know that log of negative number is not defined.
Answer:
P = 61.70 feets
Step-by-step explanation:
Based on the information given :
For fencing , We need to calculate the perimeter of the semicircle ;
Perimeter of a semicircle is given as :
P = πr + 2r
P = perimeter ; r = Radius = 12 feets
P = 12π + 2*12
P = 12π + 24
P = 61.699111 feets
P = 61.70 feets
To. Obtain how much.
We multiply the perimeter by the cost per feet.
The following equation expresses p% of q is k.

Then we can write q% of p as:

So the answer is 1/k
Answer:
$14.80(m) + $12(n) = $95.2
Solved:
$14.80(4) + $12(3) = $95.2
Step-by-step explanation:
m represents Adults ($14.80m) | n represents Children ($12n)
4 Adults times $14.80 equals $59.2
3 Children times $12 equals $36
Add $36 and $59.2 and you get $95.2
Classify the two given samples as independent or dependent.
sample 1: the scores of 20 students who took the act
sample 2: the scores of 20 different students who took the sat
Solution: The two given samples are independent samples because in both the samples, the scores of one student will not affect the scores of other students.
Independent samples are samples that are selected randomly so that its observations do not depend on the values other observations.
