Answer:

  see below

  a = 0.66...

  b = 0.73

  c = 7/8

Step-by-step explanation:

The first two numbers, 0.73 and 0.667, are near the point that is halfway between 0.6 and 0.8. That halfway point is 0.7. The value 0.667 will be below (left) of the halfway point, so is point <em>a</em>. The value 0.73 will be above (right) of the halfway point, so is point <em>b</em>. The remaining value, 7/8, must be point <em>c</em>.

__

You may know that 7/8 = 0.875, so is nearly halfway between 0.8 and 1.

_____

The attached graph has the points color-coded.

_____

Of course you know that the overline in 0.\overline{6} indicates that digit repeats indefinitely. The value 0.667 is the number rounded to 3 decimal places.

The table shows the total cost for different numbers of jackets. Number of jackets 2 5 7 Total cost ($) 46. 50 116. 25 162. 75 W
Bond [772]

The cost price of 1 jacket is $23.25 and the cost price of 3 jackets is $69.75.

<h3>What is the cost price?</h3>

Cost price is the total amount of money to produce a given product or provide a given service.

Given cost prices for jackets are,

Jackets Cost Price

2         46.5

5         116. 25

7         162. 75

We need to calculate the cost price of 3 jackets. First, we need to find out the cost price of one jacket.

2 \; \rm Jackets =\$ 46.50

1 \;\rm Jacket = \dfrac {\$46.50}{2}

1 \;\rm Jacket = \$ 23.25

Now the cost price of 3 jackets is given as,

3\;\rm Jackets = \$23.25 \times 3

3\;\rm Jackets = \$69.75

Hence we can conclude that the cost price of 3 jackets is $69.75.

To know more about the cost price, follow the link given below.

Solve the equation -3=6x-3y for y
My name is Ann [436]

Answer:

y = 2x + 1

Step-by-step explanation:

-3 = 6x - 3y

Add 3y to both sides.

3y - 3 = 6x

Add 3 to both sides.

3y = 6x + 3

Divide both sides by 3.

y = 2x + 1

What is the multiplicity of each of the roots of the graph of f(x)=−-x^3+2x^2+3x?
DerKrebs [107]

Answer:

A. -1, multiplicity 1; 0, multiplicity 1; 3, multiplicity 1.

Step-by-step explanation:

Let f(x) = -x^{3}+2\cdot x^{2} + 3\cdot x, to determine its roots and multiplicities we proceed to factorize the polynomial:

1) -x^{3}+2\cdot x^{2} +3\cdot x Given

2) x\cdot (-x^{2}+2\cdot x + 3) Distributive property

3) x\cdot (x-3)\cdot (x+1) Quadratic formula/Result

The roots and multiplicities of f(x) = -x^{3}+2\cdot x^{2} + 3\cdot x are:

<em>0 (multiplicity 1)</em>

<em>3 (multiplicity 1)</em>

<em>-1 (multiplicity 1)</em>

Therefore, the correct answer is A.
