First we have to find the area. To do that, we first have to find the side lengths of the square. Since a square has all four sides same length, we can find this by dividing: 52/4 = 13
Now we'll find the area in square meters: 13 * 13 = 169
So the area is 169 square meters.
So to find out how much that will cost, we will multiply the number of square meters by the amount it cost per square meter: 169 * $5 = $845
So it will cost $845
Answer:
10x² - 11x - 6
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor
(5x + 2)(2x - 3)
= 5x(2x - 3) + 2(2x - 3) ← distribute both parenthesis
= 10x² - 15x + 4x - 6 ← collect like terms
= 10x² - 11x - 6 ← in expanded form
1/20 a gallon I'm pretty sure. 4/5 gallon is equal to 0.8 minus 3/4 or .75 is equal to 0.05 which is 1/20.
Answer:
Time taken to reach maximum height=0.875 seconds
Maximum height = 78.25 ft
Step-by-step explanation:
The function which models the height of the ball is given as:
The function s(t) reaches its maximum height at the axis of symmetry. For a quadratic equation of the form 
, the axis of symmetry occurs at 
.
In s(t), a=-16, b=28
The ball reaches its maximum height after 0.875 seconds
(b)Maximum Height
Given
At t=0.875
Maximum height = 78.25 ft
