The axis of symmetry of h(x) = 5x2 + 40x + 64 = -4
The formula for calculating the axis of symmetry is expressed as:
Axis of symmetry x = -b/2a
h(x) = 5x^2 + 40x + 64
a = 5 and b = 40
Answer:
1/6 of one pan of brownies remains
Step-by-step explanation:
2 - 1 and 5/6 equals 1/6
3z - 7 = 14 |add 7 to both sides
3z = 21 |divide both sides by 3
z = 7
Answer:By multiplying with (1+0.01x) where x is the percentage of increase, monthly pay rate of 21$ after marked up 78.7% and 10% profit will be $41.28.
Step-by-step explanation:
Given that pay rate is 21$ and it is marked up by 78.7% and made a 10% profit.
If any value marked up or made a profit of x% then we have to multiply with (1+0.01x) to find the new value.
New pay after 78.7% marked up using above formula is 
Now we have to use above formula again for 10% profit.
Hence new value
≈$41.28
