Answer:
Sorry my mistake, it is actually worded as "f(x) =(x+6)^2"
Explanation:
y
=
(
x
+
6
)
2
with
x
≥
−
6
, then
x
+
6
is positive, so
√
y
=
x
+
6
And
x
=
√
y
−
6
for
y
≥
0
So the inverse of
f
is
g
(
x
)
=
√
x
−
6
for
x
≥
0
Answer:
Step-by-step explanation:
9th square number = 81
5th square number=25
81-25=56
56 is a multiple of 8 as 8 x 7=56
Answer:
Step-by-step explanation:
His original gross monthly salary was $1083.34. This means that the total amount that he earned that he earned in the first 6 months would be
6 × 1083.34 = $6500.4
After working satisfactorily for 6 months, Dave received a 7% raise. The amount by which it was raised would be
7/100 × 6500.4 = $455.00
His salary for the next 6 months would be
6500.4 + 455.00 = $6955.40
Dave's gross annual salary would be
6955.40 + 6500.4
= $13455.8
The equation is r(x) = 10x - 0.025x² where x is measured in thousands of toys produced, and r(x) is measured in thousands of dollars.
For maximum r, r'(x) = 0
It becomes: r'(x) = 
= 

x= 200
Hence, r(200) = 
Solving it we get,
r(200) = 1000
Hence, maximum revenue the company can earn with this toy is $1000.
Answer:
Doing an additional ANOVA
Explanation:
Analysis of variance(ANOVA), developed by Ronald Fisher is a method used to statistically measure the difference between means of different variables. While the t test measures difference between two population means, analysis of variance measures the difference for more than two population means. There is the one way ANOVA and two way ANOVA that test the difference between means.
