Ebba is buying bulk fabric.

-Dominant- [34]

Answer:

To find the cost per yard, divide the cost by the amount:

p: 6.25 / 6.5 = 0.96 --> The cost per yard is $0.96

r: 3 /4 = 0.75 --> The cost per yard is $0.75

b: 8.1 /8.5 = 0.95 --> The cost per yard is $0.95

s: 7.2 / 6 = 1.2 --> The cost per yard is $1.20

In order from cheapest to most expensive:

Red

Brown

Answer:

y = -3x^2 -9x +30

Step-by-step explanation:

When a polynomial has a zero at x=p, it has a factor of (x -p). The factors of your quadratic are ...

f(x) = (x +5)(x -2)

At the point x=3, the value of this product is ...

f(3) = (3 +5)(3 -2) = (8)(1) = 8

In order for that value to be -24, it needs to be multiplied by a scale factor of -3. The quadratic you want is ...

y = -3(x +5)(x -2)

y = -3x^2 -9x +30 . . . . . standard form

Please help geometry

Answer:

The answer to your question is 11.4 units

Step-by-step explanation:

Data

A (-3, -1)

B ( 0, 3)

C ( 1, 2)

Perimeter = ?

Formula

d = $\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}}$

Process

1.- Find the length between the points

dAB = $\sqrt{0 + 3)^{2} + (3 + 1)^{2}}$

dAB = $\sqrt{3^{2}+ 4^{2}}$

dAB = $\sqrt{9 + 16}$

dAB = $\sqrt{25}$

dAB = 5

dBC= $\sqrt{(1 - 0)^{2} + (2 - 3)^{2}}$

dBC = $\sqrt{1^{2} + (-1)^{2}}$

dBC = $\sqrt{1 + 1}$

dBC = $\sqrt{2}$

dAC = $\sqrt{(1 + 3)^{2} + (2 + 1)^{2}}$

dAC = $\sqrt{4^{2} + 3^{2}}$

dAC = $\sqrt{16 + 9}$

dAC = $\sqrt{25}$

dAC = 5

2.- Perimeter

P = AB + BC + AC

P = 5 + $\sqrt{2}$ + 5

P = 10 + $\sqrt{2}$

P = 10 + 1.42

P = 11.4
