Answer:
The vertex of a parabola is (h,k)
Step-by-step explanation:
The vertex form of a parabola is y=a(x-h)^2+k where a is the stretch/compression factor and (h,k) is the vertex. So to find the vertex, you will need (h,k) which represents the horizontal and vertical shift of the parabola

A store called Surfmania sells a $170 surfboard for 30% off. Another store, Coolwaves, advertises the same $170 surfboard for 10% off, but then offers to reduce that sale price by 20%. Which store has the better deal, and what is the savings compared to the other store? Surfmania, $3.40 in savings Surfmania, $3.40 in savings Surfmania, $5.60 in savings Surfmania, $5.60 in savings Coolwaves, $3.40 in savings Coolwaves, $3.40 in savings Final prices are the same. Final prices are the same.
Answer:
Surfmania, $3.40 in savings
Step-by-step explanation:
First, find the price with Surfmania:
170(0.7)
= 119
Find the price with Coolwaves now:
170(0.9)
= 153
153(0.8)
= 122.4
Now, find the amount in savings:
122.4 - 119
= 3.4
So, Surfmania has the better deal with $3.40 in savings.

A 35 ft ladder reaches a
window that is 25 feet high. What is the angle of
elevation the ladder forms with the ground?
A. 44.4
B 54.5
C. 35
D. 45.6
Answer:
45.6Step-by-step explanation:
The set up is right angled
Length of the ladder = Hypotenuse = 35ft
Height of window = opposite = 25ft
Using SOH CAH TOA
sin theta = opp/hyp
sin theta = 25/35
sin theta = 5/7
theta = arcsin(5/7)
theta = arcsin()0.7143)
theta = 45.6
Hence the angle of elevation is 45.6

Complete the remainder of the table for the given function rule: y = 4 - 3 -4 0 4 8 12 0 0 y7 4 [?]
Answer:
1, -2, -5
Step-by-step explanation:
To find the y value when given x, simply replace the x in the equation with the number given.
X = 4
y = 4 - [tex]\frac{3(4)}{4}[/tex] = 4 - 12/4 = 4 - 3 = 1
x = 8
y = 4 - [tex]\frac{3(8)}{4}[/tex] = 4 - 24/4 = 4 - 6 = -2
x = 12
y = 4 - [tex]\frac{3(12)}{4}[/tex] = 4 - 36/4 = 4 - 9 = -5
Do the fractions in the table convert to repeating or terminating decimals in each row of the table select either repeating decimal or terminating decimal as your answer

$250 is invested into an account that earns 5 ½ % simple interest for 10 years. What is the account total?
Answer:
$387.50
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year,
then, solving our equation
I = 250 × 0.055 × 10 = 137.5
I = $ 137.50
The simple interest accumulated
on a principal of $ 250.00
at a rate of 5.5% per year
for 10 years is $ 137.50.

The cost of 5 squash and 2 zucchini is $132 Three squash and 1 zucchini cost $0.73. Write a system of
equations
Answer:
s=-130.54
z=392.35
if you were to run a business like this I belive you would be losing alot of money perhaps try and check if your missing a decimal
Step-by-step explanation:
Squash=s
Zucchini=z
5s+2z=132
3s+z=.73
Im not sure why your prices are so different, but I think you may have forgotten a decimal point.
set z by itself using the 2nd equation
z=-3s+.73
substitute the equation into the first one
5s+2(-3s+.73)=132
expand
5s-6s+1.46=132
move the 1.46 to the other side and simplify
-s=130.54
s=-130.54
now put this back into one of the equations to find z
3(-130.54)+z=.73
z=392.35

Answer:
x=11
Step-by-step explanation: since all the angles in the triangle equal 180, you take the angle you already have, 76, But because the sides are equal, the angle adjacent to the 76 is also 76. Now you add 76 and 76, 152, then you subtract that from 180, which is 28. You now take the 28 and put it equal to the 3x-5 and solve for x.

72.9g of sugar is needed to make 9 cakes. How much sugar is needed for 6 cakes?
Answer:
48.6g
Step-by-step explanation:
72.9 / 9 = 8.1 (divide by 9 to get the amount of sugar needed for 1 cake)
8.1 x 6 = 48.6 (multiply it by 6 to get the amount of sugar needed for 6 cakes)
Which of the following best describes a triangle with one right angle and two congruent sides?
A right scalene triangle
B. acute scalene triangle
C. right isosceles triangle
D acute isosceles triangle
Answer:
C
Step-by-step explanation:
A is impossible. You cannot have both a right triangle and in the same triangle have an angle in it that is over 90 (that's the meaning of scalene)
B is sort of true, but only sort of. All scalene triangles have an angle over 90 and 2 acute angles.
C this is the answer to the question. It has 1 right angle and 2 equal sides. The two equal sides make it isosceles and the right angle is given.
D an acute triangle has three angles under 90 that add to 180. Not the right description.
A triangle with one right angle and two congruent sides is described as a "right isosceles triangle." (Option C)
Let's break down the terms:
1. Right Angle: A right angle is an angle that measures exactly 90 degrees.
2. Isosceles Triangle: An isosceles triangle is a triangle with at least two sides of equal length (congruent sides).
3. Right Isosceles Triangle: A right isosceles triangle is a special type of isosceles triangle where one of the angles is a right angle (90 degrees) and the other two angles are equal, each measuring 45 degrees.
In a right isosceles triangle, the two congruent sides are the legs of the right triangle, and the third side (opposite the right angle) is called the hypotenuse.
So, among the given options, the best description for a triangle with one right angle and two congruent sides is a "right isosceles triangle" (Option C).
