What is the vertex for the quadratic
y = 2(x-3)^2 - 4? Type as (h.k)
Answers
Answer:
(3,-4)
Step-by-step explanation:
You can find the vertex where x = -b/2a
To find the values of a and b, it would be easier to write the equation in standard form, which is y = ax^2 + bx + c
y = 2(x^2 - 6x + 9) - 4
y = 2x^2 - 12x + 18 - 4
y = 2x^2 - 12x + 14
In this equation, a = 2 and b = -12.
So let's plug that into x=-b/2a
x = -(-12)/2(2)
x = 12/4
x = 3
Now we have the x, we can just plug that into the original equation and get the y coordinate for the vertex.
y = 2(x - 3)^2 - 4
y = 2(3 - 3)^2 - 4
y = -4

Calculate the area of the parallelogram, giving your answer correct to 3 significant figures.
Answers
Answer:
114 units²
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, so
AB = CD , that is
13x - 7 = 5x + 9 ( subtract 5x from both sides )
8x - 7 = 9 ( add 7 to both sides )
8x = 16 ( divide both sides by 8 )
x = 2
Then
5x + 9 = 5(2) + 9 = 10 + 9 = 19
3x = 3(2) = 6
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height ), thus
A = 19 × 6 = 114 units²

-10(x + 21) = -15x + 18
What value of x makes the equation true?

x = 45.6
Explanation:
-10(x + 21) = -15x + 18
-10x - 210 = -15x + 18
-210 = -5x + 18
-228 = -5x

In 1984 the average American used to eat 55.7 pounds of chicken. This was 2.8 pounds more than the 1982 average. By what percent did chicken consumption increase from 1982 to 1984?
Answers
To solve this, we need to use the z statistic. The formula for z score is:
z = (x – u) / s
where x is sample value = less than 90, u is the sample mean = 90.6, s is the standard deviation = 17.2
z = (90 – 90.6) / 17.2
z = -0.035
From the standard distribution tables:
P (z = -0.035) = 0.4860
Therefore there is about 48.60 % chance that it will be less than 90 pounds

Tiffany makes a round pizza. She wants to put a cheese layer on the pizza. If the pizza has a diameter of 18 cm, how many square cm of cheese layer does she need to put on the pizza?
Answers
Answer:
[tex]A=254.46\ cm^2[/tex]
Step-by-step explanation:
Given that,
The diameter of the pizza, d = 18 cm
We need to find the square cm of cheese layer does she need to put on the pizza.
We know that the area of the circle is given by :
[tex]A=\pi r^2[/tex]
Where
r is the radius of the circle
Here, r = 9 cm
So,
[tex]A=\pi (9)^2\\\\A=254.46\ cm^2[/tex]
So, the area of the pizza is [tex]254.46\ cm^2[/tex].

Alex is trying to save $230 to buy a new tablet. Right now, he has $40 and can save $38 a week from
his allowance. Write and solve an inequality that can be used to find the minimum number of weeks it
will take Alex to have the money to buy the tablet. Write a sentence to interpret your solution.
Answers
Answer:
Step-by-step explanation:
So we know that Alex is trying to save $230.
He already has forty dollars so we can take forty away from two hundred and thirty. This leaves us with $190 that we need to save.
If he is saving $38 per week. We can divide or estimate and multiply. I prefer to multiply so that is the method I will use right now.
38×5= 190
Therefore, Alex will have enough money to buy a tablet in five weeks.
I hope I am correct and I explained this in a way that you can understand and do it yourself next time.
