The graph shows that the function is equal to y = 2cos(3x) + 1 because in the graph I notice that the table is (0, 3), (60°, -1), and (120°, 3). It shows that a is equal to 2, b is equal to 3, and c is equal to -1, making the function equal to y = 2cos(3x) + 1
a = 2
b = 3
c = 1
Large sphere's radius = R,
small sphere's radius = r, R = 8r
surface area of a sphere (SA) = 4×pi×radius^2
So what we need is the SA of the larger in terms of the smaller sphere, so if:
SA (of R) = 4×pi×R^2, then plug in "8r" for "R"...
SA = 4×pi×(8r)^2 = 4×3.14×64r^2
SA = 12.57×64r^2 = 804 r^2
Therefore the SA of the larger sphere is 804 times the SA of the smaller sphere.
I hope that makes sense!
Answer:
hopefully this
Step-by-step explanation:
divide the numerator and denominator of the given rate by the denominator of the given rate.
example you have 30 kids in a class but five pizzas how many slices can each kid get?
givens :30 kids, 5 pizzas, x slices
30 divided by 5 is 6 slices
Using the t-distribution, it is found that the value of the test statistic is t = -87.3.
At the null hypothesis, it is <u>tested if the mean is of 2,463 square feet</u>, that is:
At the alternative hypothesis, it is <u>tested if the mean is smaller</u>, that is:
.
We have the <u>standard deviation for the sample</u>, hence, the <em>t-distribution</em> is used to solve this question.
The test statistic is given by:
The parameters are:
is the sample mean.
is the value tested at the null hypothesis.
- s is the standard deviation of the sample.
The values of the <em>parameters </em>are: 
.
Hence, the value of the <em>test statistic</em> is:
