Answer:
[tex]x=4[/tex]
Step-by-step explanation:
We have the function:
[tex]f(x)=-2(x-4)^2+2[/tex]
This is a quadratic in vertex form:
[tex]f(x)=a(x-h)^2+k[/tex]
Where (h, k) is the vertex.
So, according to the equation, h=4 and k=2.
Hence, our vertex is at (4, 2).
Remember that the axis of symmetry is the vertical line that passes through the x-coordinate of the vertex.
Hence, our axis of symmetry is x=4.
Read the excerpt from "Healthy Eating." "Cherish the season," is her motto. If kids want something out of season, it's OK to buy frozen. Then steel yourself for some complaining and use the opportunity to convey a larger lesson. "It's important to teach children that you don't always get what you want," she said. Which statement best describes the author’s argument in this part of the article? Frozen foods are a necessary part of a balanced diet. Frozen foods can be a good substitute for fresh foods. Parents should do what they can to please picky eaters. Children often request foods that are unhealthy for them.

Answer:
B (Frozen foods can be a good substitute for fresh foods.)
Step-by-step explanation:
because in the text: cherish the season," is her motto. If kids want something out of season, it's OK to buy frozen. Then steel yourself for some complaining and use the opportunity to convey a larger lesson. so i think its be because there kind of saying that its ok to have frozen food in the winter because its expensive to get fresh food in winter.

Answer:
y= 4x -5 x^-1
Step-by-step explanation:
xy'+y=8x
y' + y/x =8
linear DE
integrating factor = e^∫1/x dx = x
y = 1/x ( ∫8x dx +C)
y= 1/x (4x^2 +C)
y= 4x + C x^-1
C is any constant.. in this case -5 is satisfying equation

Solve 5(w-2)=-2(1.5w+5) plz and thank you
Step-by-step explanation:
5(w-2)=-2(1.5w+5)
5w-10=-3w-10
8w=0
w=O
Answer:
W=0
Step-by-step explanation:
5(w-2)=-2(1.5w+5)
5w-10= -3w-10
5w+3w=-10+10

You are going to have a quiz with 5 true/false questions next Friday. You
want to find the probability of passing the quiz, if you guess on each
question.
Create a simulation that would represent this situation and complete 10
trials. Show all of your work for full credit.
Based on the binomial probability principle, the probability of passing the quiz if all answers are guessed [tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]
Let :
Number of questions passed = kNumber of trials, n = 10Probability of success, p = 1/2 = 0.50q = 1 - p = 1 - 0.50 = 0.50Using the binomial probability relation :
[tex] P(x = x) = nCx \times p^{x} \times q^{n-x} [/tex] x = kSubstituting the values into the relation :
[tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]
Hence, the required probability expression is [tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]

Before multiplying fractions change any mixed numbers to
[A] decimals
[B] estimated numbers
[C] percent
[D] improper fractions
9514 1404 393
Answer:
[D] improper fractions
Step-by-step explanation:
The usual recommendation for doing much of anything with mixed numbers is to change them to improper fractions.
__
However, that isn't always necessary. If you're doing the arithmetic with a calculator, it can be helpful to convert them to decimal numbers.* Sometimes, you can work with mixed numbers by working with the integer and fractional parts separately.
Sometimes a simple rewrite makes working with mixed numbers easier. (That is, converting part of the integer portion to a fraction may be useful in some cases.
Example:
(29 1/3) × (1/2) = (28 4/3) × (1/2) = 14 2/3
_____
* Some calculators will do arithmetic directly with mixed numbers and/or fractions. If yours doesn't, it can be helpful to memorize the decimal equivalents of a few common fractions: 1/3, 2/3, 1/6, 1/7, 1/9, 1/11 for example. This will help you convert the decimal result back to a mixed number.

Let f be a function such that f(2) ≤ f(x) for all values of x in the interval (0, 3). Does f(2) represent a relative minimum or a relative maximum?
Answer: f(2) is a relative minimum
This is because f(2) is the lowest y output for any given y = f(x) output on the interval [tex]0 < x < 3[/tex] which is what the interval notation (0,3) indicates.
Draw out a "parabolic" like shape where the lowest point occurs at (2, f(2)), where f(2) is unknown, but we at least know that x = 2. I put "parabolic" in quotes because it may not be a true parabola, but it looks like one. This lowest point only applies for the neighbor hood [tex]0 < x < 3[/tex].

Which expression is equivalent to the expression shown below?
20 + 8y - 9y - 21
Select each correct answer.
2(10 + 4y - 7y - 19)
2(10 + 4y) - 3(3y - 7)
4(5 + 2y - 5y - 17)
4(5 + 2y) - 3(3y + 7)
-(y + 1)
-(1 - y)
y - 1
Answer:
4(5+2y)=3(3y+7) and -(y+1)
Step-by-step explanation:
You combine like terms
20-21 =-1
8y -9y = -1y
so your answer is anything that is the same as -1 - y
2(10+4y-7y-19) =2( -3y-9) = -6y-18 NO
2(10 +4y) - 3(3y-7) = 20 +8y - 9y +21 = -y +41 NO
4(5+2y-5y-17)= 4(-3y -12) = -12y -48 NO
4(5+2y) - 3(3y+7) = 20 +8y - 9y -21 = -1 = y YES
-(y+1)= -y-1 YES
-(1-y) = -1+y NO
