Answer:
24.012
Step-by-step explanation:
y=kx^2
54=81k
k=54/81
k=0.667
y=kx^2
y=0.667×36
y=24.012

Answer:
A: the graph will cross the x-axis
Answer:
b = 30 degrees.
Step-by-step explanation:
Two angles are said to be complement of each other if their sum is 90 degrees
________________________
given
one angle is b
let other angle be x
given that angle b is one-half the measure of its complement
thus, mathematically we can the above statement as
b = 1/2(x)
now sum of both the angle will be 90 degrees as they are complementary
b + x = 90
using b = 1/2(x)
=> 1/2(x) + x = 90
=> x/2 + x = 90
=> (x +2x)/2 = 90
=> 3x = 180
=> x = 180/3 = 60
thus,
b = 1/2(x) = 1/2(60) = 30
thus, measure of angle b is 30 degrees.
There are two equations in the system of equations in this problem.
Let x = lemonade and y = hot dogs
First equation
x + y = 86
This says that the total sold hot dogs and lemonades add up to 86 sold.
Second equation
2x + 5y = 330
This says that $2 for each lemonade, $5 for each hot dog. The total amount earned is $330.
Only these two equations are true and needed.
