Answer:
x^2 / 4pi
Step-by-step explanation:
The area of a circle is (pi x r)^2
The circumference of a circle is 2pi x r
The find the radius, you need to divide x by 2pi, so x / 2pi
Then just plug it in as the radius:
(pi x (x / 2pi))^2 = x^2 / 4pi

Answer:
[tex]\frac{2/3}{1}[/tex] and [tex]\frac{3}{1}[/tex]
Step-by-step explanation:
Options
[tex]\frac{1}{1/3}[/tex] [tex]\frac{2/3}{1}[/tex] [tex]\frac{2}{3}[/tex] [tex]\frac{3}{1}[/tex] [tex]\frac{1}{9}[/tex]
Required
Select the unit rates
Unit rate involve two items where the first item being measured can be any positive number, but the second item must be measured in units (i.e. 1)
For clarity:
If [tex]\frac{a}{b}[/tex] represents unit rate, then [tex]b = 1[/tex]
Having said that:
Only [tex]\frac{2/3}{1}[/tex] and [tex]\frac{3}{1}[/tex] satisfy the condition of unit rates; others are not because they have a denominator other than 1

Let f(x) = x² - 9 and g(x) = x4. Simplify or evaluate the function g(f(u)).
Find g(f(u)). Do not expand your answer.
g(f(u)) =
Step-by-step explanation:
Let u represent x.
g[f(u)]
= g(u² - 9)
= (u² - 9)⁴.
The answer is (u² - 9)⁴.

Principal ordered 100 pizzas for a total of $1255. Cheese pizza was $11.50 each, and Pepperoni pizza was $13.00 each. Write a system of linear equations that can be used to determine c, the number of cheese pizzas the Principal ordered, and p, the number of pepperoni pizzas the Principal ordered.
Answer: c+p=100
11.50c+13p=1255
Step-by-step explanation: Since cheese pizzas cost $11.50 and pepperoni pizzas cost $13.00, then you would plug them into an equation where they equal to the total cost, $1255.
11.50c + 13p = 1255

Estimate the difference of 450.012 and 57.876 to the nearest hundredth. A. 392.1 B. 392.13 C. 392.136 D. 392.14
Answer:
C
Step-by-step explanation:
Sorry if im wrong i tried my best
Answer:
450.012 - 57.876 = 392.136
392.136 rounds to 392.14,so your answer would be D
An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 7.1 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 24 engines and the mean pressure was 7.3 pounds/square inch with a standard deviation of 1.0. A level of significance of 0.025 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
Answer:
Step-by-step explanation:
Given that:
Population Mean = 7.1
sample size = 24
Sample mean = 7.3
Standard deviation = 1.0
Level of significance = 0.025
The null hypothesis:
[tex]H_o: \mu = 7.1[/tex]
The alternative hypothesis:
[tex]H_a: \mu > 7.1[/tex]
This test is right-tailed.
[tex]degree \ of \ freedom= n - 1 \\ \\ degree \ of \ freedom = 24 - 1 \\ \\ degree \ of \ freedom = 23[/tex]
Rejection region: at ∝ = 0.025 and df of 23, the critical value of the right-tailed test [tex]t_c = 2.069[/tex]
The test statistics can be computed as:
[tex]t = \dfrac{ \hat X - \mu_o}{\dfrac{s}{\sqrt{n}}}[/tex]
[tex]t = \dfrac{ 7.3-7.1}{\dfrac{1}{\sqrt{24}}}[/tex]
[tex]t = \dfrac{0.2}{0.204}[/tex]
t = 0.980
Decision rule:
Since the calculated value of t is lesser than, i.e t = 0.980 < [tex]t_c = 2.069[/tex], then we do not reject the null hypothesis.
Conclusion:
We conclude that there is insufficient evidence to claim that the population mean is greater than 7.1 at 0.025 level of significance.
The function f(x)= (x– 4)^3
is transformed to g(x)= (x+3)^3– 4
What transformations are performed from function f to function g?
Choose each correct answer.
0 Function f is translated to the left 4 units.
✓ Function f is translated to the left 7 units.
O Function fis translated to the right 7 units.
Function fis translated down 4 units.
Answer:
Function f(x) is translated left 7 units and down 4 units
(x-4) --> (x+3)
+7 = translation left 7 units
-4 at end affects y (down 4 units)
The transformations are performed from function f to function g is
Function f(x) is translated left 7 units and down 4 units.
What is dilation?The process of resizing an object is known as dilation. Dilation allows the items to be enlarged or shrunk. This transformation yields a shape that is identical to the source image. The size of the form, on the other hand, varies. A dilatation should either lengthen or shorten the original form. This shift is referred to as the scale factor.
We have function,
f(x) = (x - 4)³
and, g(x) = (x+ 3)³ - 4
Here, we can see the following transformation
(x-4) --> (x+3)
So, here the function translated 7 unit left and 4 units down.
Hence, Function f(x) is translated left 7 units and down 4 units.

What percent of the bottle of apple juice is water?
Answer:
40% of the bottle of apple juice is water
75% of the bottle of orange juice is water
Step-by-step explanation:
this is to find the percentage of apple juice that is water
(32 ÷ 80) × 100
you have to multiply by 100 because you are looking for the percentage
32÷ 80 is 2/5
2/5 × 100 is 40%
this is to find the percent of orange juice that is water
(48÷64) × 100
48 ÷ 64 is 3/4
3/4 × 100 is 75%

P is directly proportional to M and inversely proportional to N. If P = 9 when M = 24 and N = 8, find the value of P when M = 5 and N = 6.
Please I need the solvings to this question
Answer:
2.5
Step-by-step explanation:
P = k*M /N
9 = k * 24/8
9 = k * 3
k = 3
if M=5 and N=6
P = 3 * 5/6 = 5/2 = 2.5

a bag of 20 counters
16 of the counters is green
a counter is picked at random
what is the possibility that it is green
give your answer as a fraction
Answer:
16/20
Step-by-step explanation:
becuase there is 20 counters and 16 of them are green
so if he picks one of 20 there are 16 green ones he could pick which is is a higher probabilty then the other colors.
Answer:
1.25
Step-by-step explanation:
You divide the number of outcomes by the number of possible outcomes. So, 20/16 which equals 1.25.
