The function of the parabola will be f(x) = -2(x²+2x-15)
<h3>Equation of a parabola</h3>
The equation of a parabola are quadratic in nature.
If s graph has intercepts (a, 0) and (b, 0), the function will be equivalent to;
f(x) = (x-a)(x-b)
Since we are given the x-intercepts (-5, 0) and (3, 0), the function of the parabola will be:
f(x) = (x+5)(x-3)
Expand
f(x) = x^2 - 3x + 5x - 15
f(x) = x^2 + 2x - 15
Hence the function of the parabola will be f(x) = -2(x²+2x-15)

65=.65
65 is 65 pieces out of 100 so 65/100
Answer:
80
Step-by-step explanation:
20 x 4 = 80
First group rate is x+10, Second is x
First group made 160, Second made 120
Time the first group will take is 160/x+10, and second is 120/x
Equation is: 160/x+10 + 4 = 120/x
x=10, x=-30
The second group made 10 suits everyday.
Convert all the numbers to real numbers:
6√3 = 10.3923
(3.5)^2 = 12.25
√75 = 8.660
9.8 = 9.8
57/5 = 11.4
A) Now order from largest to smallest:
(3.5)^2, 57/5, 6√3, 9.8, √75
B) We found the order by solving the equations to get real numbers.
C)
Since the numbers are multiplied by a negative number, the greatest number would be the smallest number because it would be closer to zero.
The order would be the reverse of part A:
x√75, 9.8x, 6x√3, 57x/5, x(3.5)^2
D) I replaced x with -1 and calculated for real numbers. All the values were the same as A except they were the negative value.
