60% of the sodas served were regular
Step-by-step explanation:
Add 51+34=85.
51 over 85=0.6
0.6 times 100= 60%
Answer: f(x) = x²
<u>Step-by-step explanation:</u>
The vertex form of a quadratic equation is: f(x) = a(x - h)² + k where;
- |a| is the vertical stretch
- -a is a reflection across the x-axis
- (h, k) is the vertex
The parent function is where a = 1 and the vertex is at the origin <em>(h, k) = (0, 0)</em>
→ f(x) = 1(x - 0)² + 0
⇒ f(x) = x²
Answer:
5sqrt(5) = q
-5sqrt(5) = q
Step-by-step explanation:
f(q) = q^2 -125
To find the roots set the equation equal to zero
0 = q^2 -125
Add 125 to each side
125 = q^2 -125+125
125 = q^2
Take the square root of each side
±sqrt(125) = sqrt(q^2)
±sqrt( 5*25) = q
±sqrt( 25)* sqrt(5) = q
±5* sqrt(5) = q
±5sqrt(5) = q
n = last test
(87 + 78 + 61 + n) : 4 = 78,5
87 + 78 + 61 + n = 78,5 x 4
n = 314 - 226
n = 88
