Answer:
therefore y= - (x-2)^2 + 5
Step-by-step explanation:
u do this by using this format here ..,
y=a(x-h)^2+k
sub in the vertex points as h=2 and k = 5 , since the 2 is positive its sign will be -2 in the brackets because when solving for x-2=0 it is x=2
y=a(x-2)^2+5
then with your (0,1) points plug that in as y and x
1=a(0-2)^2+5
1=a(-2)^2+5
1=4a+5
1-5=4a
-4=4a
a=-1
therefore y= - (x-2)^2 + 5
What reason can you give for the fact that if two angles are congruent then their
measures are equal?
(I think it’s a type of postulate)
Answer:
Explained below
Step-by-step explanation:
If two angles are congruent, it means that they have the same angle whether in degrees or radians.
Now, angles are said to be congruent so as long as the measure of the angles are the same and regardless of them point in the same or different directions.
They must not necessarily be made with lines having the same length.
For example, in the diagram of the 2 triangles I've attached, angle C and Z are congruent, and they are both marked accordingly by one short curved line. Similarly angle A and B are congruent and they are both marked accordingly by two short lines.
What is the general equation of the line that passes through (4, -1) and (-2, 3)?
Answer:
y=-2/3x+7
Step-by-step explanation:
(4, -1) and (-2, 3)
m=y²-y¹/x²-x¹
m=3-(-1)/(-2)-4
m=4/-6
m=-2/3
y-y=m(x-x1)
y-(-1)=-2/3(x-4)
y+1=-2/3x+8
-1 -1
y=-2/3x+7

Jaydin had 0.75 of a cake left over from his party. Three of his friends shared the cake equally. How much cake did each friend eat.
Answer: .25
Step-by-step explanation:
Answer:
If you asking how much was shared from if the three friends and the .75 it would be .25 each because .75/3 is .25. But if your asking how much did the three friends eat if the .25 is what they split then the answer would be 1/12 or .08333333

In an effort to reduce accidents, the highway authority decided to reduce the speed limit on a road from 65 mi/h to 50 mi/h. To travel 650 miles, how many more hours will it take a car averaging 50 mi/h than a car averaging 65 mi/h?
Answer:
The answer is 3 hours
Step-by-step explanation:
The reason being, 65 mi/h can be divided by 650 to equal 10, so it would take 10 hours to get through those 650 miles with your car that drives 65 mi/h
Then we can do the same things with 50, that equals 13. So 13 - 10 = 3. It took the 50 mi/h car 3 more hours to get through 650 miles than the 65 mi/h car!
Hope this helped :)

You have to make sure to add like terms. In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.

Answer:
D
Step-by-step explanation
When rounding, you want the number to change as little as possible. It is easier for the number to be 250 instead of 200 because 229 is closer to 250. in the same way, 3.22 is closer to 3 than 4. Now to check this, if you do 229 x 3.22, you get 737.38. Now looking at the answer choices, this is most definitely closest to 750. Given all this, I think it is safe to say D is the answer.

P varies inversely with x. If P = 7 when x = 8, find the value of P when x = 7.
Answer:
P = 8
Step-by-step explanation:
Given that P varies inversely with x then the equation relating them is
P = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition P = 7 when x = 8 , then
7 = [tex]\frac{k}{8}[/tex] ( multiply both sides by 8 )
56 = k
P = [tex]\frac{56}{x}[/tex] ← equation of variation
When x = 7 , then
P = [tex]\frac{56}{7}[/tex] = 8
The value of P when x = 7 is 7 and can be determined by using the arithmetic operations and given data.
Given :
P varies inversely with x.P = 7 when x = 8.The following steps can be used to determine the value of P when (x = 7):
Step 1 - Given that P varies inversely with x. That is:
[tex]\rm P \;\alpha \;\dfrac{1}{x}[/tex]
Step 2 - The above expression can be written as:
Px = K ---- (1)
where K is the proportionality constant.
Step 3 - Now, it is given that P = 7 when x = 8. Put the value of P and x in the above equation.
[tex]\rm 7\times 8 = K[/tex]
56 = K
Step 4 - Put the value of K = 56 and x = 7 in the equation (1).
[tex]\rm P \times 8=56[/tex]
P = 7
So, when x = 7 the value of P is 7.

Given that the radius of the circle is
2 yd.
Step-by-step explanation:
Area of first triangle = 1/2bh
the base of the triangle = the radius of the semi-circle = 2yd
height = 5yd
Area = 1/2(5yd)(2yd)
A = 5yd(yd)
A = 5y^2d^2 squared units.
since the second triangle also has the same dimensions as the first triangle
hence:
Area of the second triangle = 5y^2d^2 squared units.
Area of semi-circle = πr^2
Area = π(2yd)^2
A = 4πy^2d^2 squared units
