Answer:
x = -4 ± i4
Step-by-step explanation:
This is a quadratic equation with coefficients {1, 8, 32}. We apply the quadratic formula to solve for x. The first step is to find the 'discriminant,' b^2 - 4 ac, which here is (8)^2 - 4(1)(32), or 64 - 128, or -64.
A negative discriminant indicates that this quadratic has two unequal complex roots.
-b ± √(b^2 - 4ac)
The formula is x = ----------------------------
2a
which, when evaluated at a = 1, b = 8 and c= 32, yields
-8 ± √(-64)
The formula is x = ----------------------------
2(1)
or:
-8 ± i√64
The formula is x = ----------------- = x = -4 ± i4

Step-by-step explanation:
A company needs to package 2,400 pencils. A box in the shape of a rectangular prism can hold 60 pencils. A cylindrical container can hold 80 pencils. Each box costs the company $0.50, while each cylindrical container costs $0.75.
Which packaging should the company use to minimize cost? Explain.
The rectangular prism boxes should be used because they will cost the company $2.50 less than using the cylindrical containers.
The cylindrical containers should be used because they will cost the company $2.50 less than using the rectangular boxes.
The rectangular prism boxes should be used because they will cost the company $5.00 less than using the cylindrical containers.
The cylindrical containers should be used because they will cost the company $5.00 less than using the rectangular boxes.
Answer:
The rectangular prism boxes should be used because they will cost the company $2.50 less than using the cylindrical containers.
Step-by-step explanation:
Box
2400/60 * .5 = 20
Cylinder
2400/80 * .75 = 22.5
Box cost 2.50 less
Answer:
a. The rectangular prism boxes should be used because they will cost the company $2.50 less than using the cylindrical containers.

Answer:
7 x 9 = 9 x 7
5 x 8 = 5 x 4 x 2
4 x 6 = 3 x 2 x 4
Step-by-step explanation:
Equation 1:
Commutative property, just reversing the order of the factors.
Equation 2:
Since 5 s given we multiply 4 x 2 to get 8
5 x 8
Equation 3:
3 and 4 are given. Since 6 is a product of 3 and 2, 2 is the missing number.

Step-by-step explanation:
Two numbers are in the ratio 3:5. If one of them is greater than the other by 10,Find the smaller number.
Answer:
smaller number = 15
Step-by-step explanation:
Let the two numbers be 5x and 3x respectively.
According to the question —
5x — 3x = 10
2x = 10
x = 5
Thus the smaller number is 3 × 5 = 15
Answer:
15?

Answer:
4) [tex]y=-\frac{1}{3} (x-2)^2-3[/tex] 7) [tex]2x^2+12x+18[/tex]
5) [tex](-2,-3)[/tex] 8) [tex](0,-3)[/tex]
Step-by-step explanation:
7) Add [tex]2y^2[/tex] to both sides of the equation.
[tex]x-12y-18=2y^2[/tex]
Add 12y to both sides of the equation.
[tex]x-18=2y^2+12y[/tex]
Add 18 to both sides of the equation.
[tex]x=2y^2+12y+18[/tex]
Use the form of [tex]ax^{2} +bx+c[/tex] to find the values of a, b, and c.
a = 2, b = 12, c = 18
Substitute the values of a and b into the formula [tex]d=\frac{b}{2a}[/tex]
[tex]d=\frac{12}{2(2)}[/tex]
Simplify the bottom.
d = 3
Find the value of e using the formula e = [tex]c-\frac{b^2}{4a}[/tex]
Raise 12 to the power of 2
[tex]e=18-\frac{144}{4(2)}[/tex]
Multiply 4 by 2.
[tex]e=18-\frac{144}{8}[/tex]
Divide 144 by 8.
[tex]e=18-1[/tex] · 18
Multiply [tex]-1[/tex] by 8.
[tex]e = 18-18[/tex]
Subtract 18 from 18.
e = 0
Substitute the values of a, d, and e into the vertex form [tex]a(x+d)^2+e[/tex].
[tex]2(y+3)^2+0[/tex]
Set x equal to the new right side.
[tex]x=2(y+3)^2+0[/tex]
Use the vertex form, [tex]x=a(y-k)^2+h[/tex], to determine the values of a h & k.
a = 2
h = 0
k = [tex]-3[/tex]
Find the vertex [tex](h,k)[/tex]
[tex](0,-3)[/tex]
how many solutions? -3(v + 4) = 2v - 37
-3(v+4) = 2v-37
-3v-12 = 2v-37
-3v-2v = -37+12
-5v = -25
v = -25/-5
v = +5
Answer:
One solution.
v = 5
Step-by-step explanation:
- 3(v + 4) = 2v - 37
- 3v - 12 = 2v - 37
- 3v - 12 + 12 = 2v - 37 + 12
- 3v = 2v - 25
- 3v - 2v = 2v - 2v - 25
- 5v = - 25
- 5v ÷ - 5 = - 25 ÷ - 5
v = 5
