Option C is correct
Select the quadratic function that has a vertex at (3, –5).
Question 3 options:
y=(x−3)2−5
y=(x−3)2+5
y=(x+3)2−5
y=(x−5)2+3
y=(x−5)2−3
y=(x+5)2+3
[tex]~~~~~~\textit{vertical parabola vertex form} \\\\ y=a(x- h)^2+ k\qquad \begin{cases} \stackrel{vertex}{(h,k)}\\\\ \stackrel{"a"~is~negative}{op ens~\cap}\qquad \stackrel{"a"~is~positive}{op ens~\cup} \end{cases}[/tex]
we know the vertex is at h = 3 and k = -5
[tex]\stackrel{vertex}{(\stackrel{h}{3}~~,~~\stackrel{k}{-5})}\qquad \implies y=(x-3)^2-5[/tex]

They are going to build wind turbines off the coast of Staten Island. It requires ⅙ square miles of land. How many turbines can be built on 8 square miles of land?
Answer:
48
Step-by-step explanation:
Here we will show you how to calculate 8 divided by 1/6. We will give you the answer in fraction form and in decimal form.
Here is 8 divided by 1/6 displayed mathematically in colors:
8
÷
1
6
The numbers in 8 divided by 1/6 are labeled below:
8 = whole number
1 = numerator
6 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
8 x 6
1
=
48
1
Thus, the answer to 8 divided by 1/6 in fraction form is:
48
1
To make the answer to 8 divided by 1/6 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
48 / 1 = 48
The answer is rounded to the nearest two decimal points if necessary.
48/1 is an improper fraction and should be written as 48.
The Nut Shack sells hazelnuts for $7.00 per pound and peanuts nuts for $5.30 per pound. How much of each
type should be used to make a 30 pound mixture that sells for $6.43 per pound?
Answer:
10.06 lbs of peanuts and 19.94 lbs of hazelnuts.
Step-by-step explanation:
lb=pound
30 lb mixture at $6.43/lb means that the total cost of the mixture is 30×6.43=192.9
Let H = weight of hazelnuts in the mixture.
Let P = weight of the peanuts in the mixture.
Set up a system of equations.
7H + 6.43P = 192.9
H + P = 30
Afterward, input the values into the equations above.
H = 30 - P
7(30-P) + 5.3P = 192.9
210 - 7P + 5.3P = 192.9
210 - 1.7P = 192.9
-1.7P + 210 = 192.9
-1.7P = 192.9 - 210
-1.7P = -17.1
P = -17.1 / -1.7 = 10.06
H = 30 - P = 30 - 10.06 = 19.94
Hence, the mixture contains 10.06 lbs of peanuts and 19.94 lbs of hazelnuts. Hope this helps and have a great day!
A searchlight rotates through one complete revolution every 36 seconds. How long does it take the light to rotate through 90°?
Answer: 1 second
1 full revolution=360
4seconds=360degrees
how many seconds are 90 degrees
4:360=x:90
4/360=x/90
simplify
1/90=x/90
1=x
the answer is 1 second

Answer:
A. The triangles are not similar to each other.
Step-by-step explanation:
[] A triangle's angles all add up to 180°
-> For triangle ABC the angles are 80°, 40°, and unknown
-> For triangle DEF the angles are 80°, 70°, and unknown
[] For triangle ABC the angles are 80°, 40°, and unknown
-> 180° - 80° - 40° = 60°
-> Triangle ABC has angles of 80°, 40°, and 60°
[] For triangle DEF the angles are 80°, 70°, and unknown
-> 180° - 80° - 70° = 30°
-> Triangle DEF has angles of 80°, 70°, and 30°
[] A. The triangles are not similar to each other.
-> Since we do not have any side lengths, we must go off of AA (angle & angle) but as AA is not true, these triangles are not similar
