Answer: x=45
Step-by-step explanation:
60/120=x/90
1/2=x/90
Given that you know that x is gonna be half 90.
So 45. Then plug it in
60/120=45/90
1/2=1/2
Or do it like
60 = x
120 90
5400=120x
Then divide 120 by 5400
5400÷120=45
The total will be 57.23. Because tax would be 4.24 and add it to 52.99 and you get 57.23.
Answer:
y= -4x^2 + 15x - 14
Step-by-step explanation:
A parabola is always in the form y = ax^2 + bx + c.
Substitute each point to produce different equations:
-14 = 0a + 0b + c = c
so c = -14
-3 = a1^2 + b1 + c = a + b - 14
so a + b = 11
0 = a2^2 + b2 + c = 4a + 2b -14 = 0
so 4a + 2b = 14
if we double a + b = 11 we get 2a + 2b = 22
Subtract this from 4a + 2b = 14 and we get 2a = -8 so a= -4 and b = 11 - a = 15
We don't need to use the (3,5) points as we have all the information we need.
Answer:
b) all interior angles are right angles
Answer:
Step-by-step explanation:
g(2) = 2(2)= 4
f(4) = 4^2 + 2(4) = 16 + 8 = 24
