Answer:
D
Step-by-step explanation:
The triangle is an isosceles triangle which means that two sides are the same, A is the same size of the equal side so A is D.
90 x .80= 72. 72 Students like hot choco, therefore 8 do no like hot choco
4/7 5/8 6/9 are some possible answers
Answer:
Option A:
y = 3*(x - 5)^2 - 4
Step-by-step explanation:
For a quadratic equation:
y = a*x^2 + b*x + c
with the vertex (h, k), we can rewrite the function as:
such that:
h = -b/2*a
y = a*(x - h)^2 + k
Here we have the function:
y = 3*x^2 - 30*x + 71
the x-value of the vertex will be:
h = -(-30)/(2*3) = 30/6 = 5
And k is given by:
k = y(5) = 3*(5)^2 - 30*5 + 71 = -4
Then the vertex is:
(5, - 4)
And we can rewrite the equation in the vertex form as:
y = 3*(x - 5)^2 + (-4)
y = 3*(x - 5)^2 - 4
Then the correct option is A.

<h3>How to calculate simple interest.</h3>
Mathematically, simple interest is calculated by using this formula:
I = PRT
<u>Where:</u>
- I is the simple interest.
- T is the time measured in years.
<u>Given the following data:</u>
Interest rate = 2% = 0.02.
Principal = $10,000.
Time = 3 years.
Substituting the given parameters into the formula, we have;
I = 10000 × 0.02 × 3
I = $600.
Amount of balance;
A = I + P
A = 600 + 10,000
A = $10,600.
