The solution is, simplification of the expression is; 71.19.
Here, we have,
the given expression is:
(5/2)^4/2 * (3/2)^6
=(5/2)^2 * (3/2)^6
as we know that, 4/2 = 2.
now, we have,
(5/2)^2 * (3/2)^6
=5²/2² ^ 3⁶/2⁶
= 5² * 3⁶ / 2² * 2⁶
=5² * 3⁶ / 2 ^ (2+6)
=5² * 3⁶ / 2 ^8

Answer:
Refer to the step-by-step.
Step-by-step explanation:
Verify the given identity.
[tex]E_0\cos^4(\theta)=E_0(\frac{1}{2} +\frac{\cos(2\theta)}{2} )^2[/tex]
Pick the more complex side to manipulate, in this case it is the R.H.S.
(1) - Apply the following double-angle identity
[tex]\boxed{\left\begin{array}{ccc}\text{\underline{Double-Angle Identity:}}\\\\\cos(2A)=1-2\sin^2(A)\end{array}\right}[/tex]
[tex]E_0(\frac{1}{2} +\frac{\cos(2\theta)}{2} )^2\\\\\Longrightarrow \boxed{ E_0\Big(\frac{1}{2} +\frac{1-2\sin^2(\theta)}{2}\Big )^2}[/tex]
(2) - Split of the right fraction
[tex]E_0(\frac{1}{2} +\frac{1-2\sin^2(\theta)}{2} )^2\\\\\Longrightarrow E_0(\frac{1}{2} +\frac{1}{2} -\frac{2\sin^2(\theta)}{2})^2\\\\\Longrightarrow \boxed{E_0(1 -sin^2(\theta))^2}[/tex]
Apply the following Pythagorean identity
[tex]\boxed{\left\begin{array}{ccc}\text{\underline{Pythagorean Identity:}}\\\\1-\sin^2(A)=\cos^2(A)\end{array}\right}[/tex]
[tex]E_0(1 -sin^2(\theta))^2\\ \\\Longrightarrow E_0(\cos^2(\theta))^2\\\\\therefore \boxed{E_0\cos^4(\theta)=E_0\cos^4(\theta)}[/tex]
Thus, the identity is verified.
It has been proven and verified that [tex]E_0cos^4 \theta = E_0(\frac{1}{2} +\frac{cos2 \theta}{2} )^2[/tex] below.
How to verify the equality of the cosine function?In Mathematics and Geometry, the standard equation of a cosine function is represented or modeled by the following mathematical equation (formula):
y = Acos(Bx - C) + D
Where:
A represents the amplitude.B = 2π/P.P represents the period.C represents the phase shift.D represents the center line (midline).In this exercise, you are required to prove that the right-hand side of the cosine function is equal to left-hand side of the cosine function;
[tex]E_0cos^4 \theta = E_0(\frac{1}{2} +\frac{cos2 \theta}{2} )^2[/tex]
From the double-angle formulas, we have:
2sin²θ = 1 - cos2θ
cos2θ = 1 - 2sin²θ
Next, we would evaluate the right-hand side of the cosine function by substituting "1 - 2sin²θ" for cos2θ as follows;
[tex]E_0cos^4 \theta = E_0(\frac{1}{2} +\frac{1-2sin^2 \theta}{2} )^2\\\\E_0cos^4 \theta = E_0(\frac{1}{2} +\frac{1}{2} -\frac{2sin^2 \theta}{2})^2\\\\E_0cos^4 \theta = E_0(1 -\frac{2sin^2 \theta}{2})^2\\\\E_0cos^4 \theta = E_0(1 -sin^2 \theta)^2\\\\[/tex]
E₀cos⁴θ = E₀(1² - (sin²θ)²)
E₀cos⁴θ = E₀(1 - sin⁴θ) ⇒ (Verified).

Salad Supreme is increasing the number of restaurants by 110% each year.
The most reasonable conclusion based on the given information is: Salad Supreme is increasing the number of restaurants by 10% each year. Option B
How to determine the most reasonable conclusionBased on the given equation y = 195(1.10)^x, where x represents the number of years since 2005 and y represents the number of Salad Supreme restaurants, we can draw the following conclusions:
A. Salad Supreme had 110 restaurants in 2005: This conclusion is not supported by the given equation.
B. Salad Supreme is increasing the number of restaurants by 10% each year: This conclusion is supported by the equation.
C. Salad Supreme is increasing the number of restaurants by 195 each year: This conclusion is not supported by the equation.
D. Salad Supreme is increasing the number of restaurants by 110% each year: This conclusion is not supported by the equation. The growth factor of 1.10 (or 10%) indicates a 10% increase each year, not 110%.
Therefore, the most reasonable conclusion based on the given information is: Salad Supreme is increasing the number of restaurants by 10% each year.

y intercepts of f((x)=x^{2}+2x-3
Answer:
The y-intercept is -3
Written as a point it is (0, -3)
Step-by-step explanation:
To find the y-intercept, let x = 0
(and to find x-intercepts, let y = 0)
So let's let x = 0
f(x) = x^2 + 2x - 3
y = x^2 + 2x - 3
y = 0^2 + 2(0) - 3
y = -3
This means the y-intercept is -3. The graph crosses the y-axis at -3. This is the point (0, -3).
Question
Evaluate |—15u| + |3v| + 3 when u
=
3 and v = 3.
The value of given expression is 57.
We are given that;
|—15u| + |3v| + 3
u=3, v = 3
Now,
To evaluate the expression, you need to substitute the values of u and v and simplify. The absolute value of a number is the distance from zero on the number line, so it is always positive or zero. You can write your solution as:
|—15u| + |3v| + 3 = |—15(3)| + |3(3)| + 3 = |—45| + |9| + 3 = 45 + 9 + 3 = 57
Therefore, by the given expression the answer will be 57.

If the Coach chooses the Three-Year Plan, what is the total amount he will spend after 12 months? ANSWER QUICK ILL GIVE BRAINLIST!
Answer:
$17,320 after 12 months.
Step-by-step explanation:
f the Coach chooses the Three-Year Plan, the total amount he will spend after 12 months can be calculated as follows:
First, we need to calculate the total amount of monthly payments made in 12 months:
12 months x $610 per month = $7,320
Then, we need to add the down payment made at the time of purchase:
$7,320 + $10,000 = $17,320
Therefore, if the Coach chooses the Three-Year Plan, he will spend a total of $17,320 after 12 months.

given that,
In a certain Integrated Math II class of 29 students, 6 of them play golf and 14 of them play soccer.
There are 9 students who play neither.
Number of students that play = 20
let, students play golf = A
students play soccer = B
so, given that,
n ( A) = 6 and, n ( B) = 14
so, total sample space = 29
now, P(A) = 6/29
P(B) = 14/29
and, P(students who play neither) = 9/29
we get, 6/29 + 14/ 29 + 9/29 = 29/29 = 1
i.e. there are no students who play both golf and soccer = 0
all the events are independent.
so, we have,
the probability that a student chosen randomly from the class plays golf or soccer = P(A) + P(B)
= 6/29 + 14/ 29
= 20/29
and, the probability that a student chosen randomly from the class plays golf and soccer = 0.

10. The total sample, 290 individuals have cats, while 306 individuals do not have cats. Furthermore, 312 individuals have dogs, while 284 individuals do not have dogs.
In order to find the marginal frequencies, we need to calculate the totals for each category separately.
For question 9:
The marginal frequency for "Set Academic Goals - yes" is 64 + 54 = 118. This represents the total number of individuals who answered "yes" to setting academic goals.
The marginal frequency for "Set Academic Goals - no" is 168 + 142 = 310. This represents the total number of individuals who answered "no" to setting academic goals.
The marginal frequency for "Male" is 64 + 168 = 232. This represents the total number of males.
The marginal frequency for "Female" is 54 + 142 = 196. This represents the total number of females.
Interpretation:
The marginal frequencies provide us with the total counts for each category in a contingency table. In this case, we can see that out of the total sample, 118 individuals set academic goals (regardless of gender), while 310 individuals did not set academic goals. Additionally, there were 232 males and 196 females in the sample.
For question 10:
The marginal frequency for "Cat - yes" is 104 + 186 = 290. This represents the total number of individuals who have cats.
The marginal frequency for "Cat - no" is 208 + 98 = 306. This represents the total number of individuals who do not have cats.
The marginal frequency for "Dog - yes" is 104 + 208 = 312. This represents the total number of individuals who have dogs.
The marginal frequency for "Dog - no" is 186 + 98 = 284. This represents the total number of individuals who do not have dogs.
Interpretation:
The marginal frequencies reveal the total counts for each category in the contingency table. In this case, we can observe that out of the total sample, 290 individuals have cats, while 306 individuals do not have cats. Furthermore, 312 individuals have dogs, while 284 individuals do not have dogs.

If a town's population doubles every 4 years, how
many people will be in the down 12 years later if the
current population is 28,100? y = ab*
The population of the town 12 years later will be 224,800 if the current population is 28,100 and the population doubles every 4 years.
Since the population doubles every 4 years, we can use the formula:
P = P0 x [tex]2^{t/4}[/tex]
where P0 is the initial population, t is the time elapsed in years, and P is the population after time t.
In this case, the initial population P0 is 28,100, and we want to know the population after 12 years, so t = 12. Substituting these values into the formula, we get:
P = 28,100 2^(12/4)
