A quadratic equation that has X-intercepts of (-2,0) and (8,0), a stretch of 3, and the vertex is a minimum.
a. Factored form equation:
b. Vertex form equation:
c. Standard form equation:

Answers

Answer:

a. y = 3 × (x + 2)(x - 8)

b. y = 3·(x - 3)² - 75

c) y = 3·x² - 18·x - 48

Step-by-step explanation:

The x-intercept of the quadratic equation are (-2, 0), (8, 0)

The stretch of the quadratic equation = 3

We have;

a. The factored form y = 3 × (x + 2)(x - 8)

b. From the vertex form, we have;

y = 3 × (x + 2)(x - 8) = 3·x² - 18·x - 48

y = 3·x² - 18·x - 48

The vertex form a(x - h)² + k

Where;

h = -b/(2·a) = 18/6 = 3

h = 3

k = c - b²/(4·a) = -48 - (18²)/12 = -75

The vertex form 3·(x - 3)² - 75

c) The standard form of the quadratic equation, y = a·x² + b·x + c

The standard form of the quadratic equation is y = 3·x² - 18·x - 48.

Sean wants to spend (example) $100 on clothing and he wants to purchase
6 additional items for his wardrobe. Each pair of pants costs $20 and each shirt costs $15.
Show the solution graphically.

Point (2, 4)

Answers

Answer:

Step-by-step explanation:

Let x be the number of pants and y be the number of shirts

x + y = 6

20x + 15y = 100

multiply the first equation by -20

-20x -20y = -120

20x + 15y = 100

subtract the equations

-5y = -20

y = 4

replace y in equation 1

x + 4 = 6

x = 2

Abe is buying wrapping paper.
He is shopping for the best deal.

Drag the rolls of wrapping paper in order from the least to the greatest unit cost in dollars per square foot.
red 12.5 square feet for $1.79
blue 40 square feet for $5.29
green 50 square feet for $8.49
orange 60 square feet for $6.00

Answers

Answer:

So you need to compute all the rates to see which is the best deal.

$1.79/12.5ft^2=$0.1432 per ft^2

$5.29/40ft^2=$0.13225 per ft^2

$8.49/50ft^2=$0.1698 per ft^2

$6/60ft^2=$0.10 per ft^2

So the last option is the cheapes per square foot and thus is the best deal. Ordered from least to greatest.

Answer:

Step-by-step explanation:

All we have to do is multiply accordingly. I'll use a for an example.

So for the value before the perentheses we multiply that by all of the values in the perentheses.

[tex]3x \: and \: - 6[/tex]

So the correct answer would be

[tex]3x - 6[/tex]

You can use the same strategy for all the questions, but I'll just answer those straight away.

Also you may notice I put the variable before the constant in question c because the variable should always go before the constant in expressions and equations.

d) on a circle with radius 4

Answers

Answer:

B) on a circle with radius 2

Step-by-step explanation:

got it right on edge :)

The 4th roots of 16i is located b) on a circle with radius 2

How to determine the location of the fourth root?

The complex number is given as:

Number = 16i

Take the fourth root

[tex]Root = \sqrt{16i[/tex]

Take the fourth root of 16

[tex]Root = 2\sqrt{i[/tex]

The number before the radicand represents the circle radius

Hence, the 4th roots of 16i is located b) on a circle with radius 2
