Answer:
a. +150, b. -15 yards, c. -75 feet, d. +35 degrees, e. -$24.75
Step-by-step explanation:
You are just evaluating the (-) and (+) symbol based off the term being used. If they are gaining something its a (+) if its a loss in any way shape or form it is a (-)
Answer:
Step-by-step explanation:
<u>Given vertices WXYZ:</u>
- W(-4,5), X(2,4), Y(3, -4), Z(-1, -6)
Perimeter is the sum of the side length.
<u>Use distance formula to find each side:</u>
- WX =
≈ 6.08 - XY =
≈ 8.06 - YZ =
≈ 4.47 - WZ =
≈ 11.40
<u>Find perimeter:</u>
- P = 6.08 + 8.06 + 4.47 + 11.40 = 30.01 units
We can make an equation from this.
Our intial value is 150 for parts, and he works for 52 dollars an hour.
We can define <em /><em>h</em> for hours and <em /><em>c</em> for total cost.
Therefore, we have:
c = 150 + 52h.
We can set this equal to 306 dollars, as that's the given total cost:
306 = 150 + 52h
Subtract 150 from both sides:
52h = 156
Divide both sides by 2:
h = 3
He worked 3 hours.
hope this helped!
Separate the root expression into the two numbers you found as factors, with each number now under its own square root symbol. For example, sqrt(12) = sqrt(4) times sqrt(3). 3) Keep simplifying. The square root of a perfect square becomes just a number, without theradical<span> square root symbol.</span>
Answer:
Step-by-step explanation:
f(x) = 1/4 x²+bx+10
the derivate is : f'(x) = 1/2 x +b
you have : f'(6)=0
1/2 (6)+b=0
3+b =0
b = -3
so f(x) = 1/4 x²-3x+10.......f(6) =1/4(6)² -3(6)+10 =9-18+10 =1
f(x) = 1/4(x-6)²+1... the vertex form
