x^3−5x^2+7x−12

Factors of 12,

Answer:

Horizontal Asymptote:    y=2

Vertical Asymptote: x=3

Step-by-step explanation:

One way: Look at graph

Look at for a horizontal or vertical line that both lines don't touch.

Second Way:

When you look for vertical asymptotes, you set the denominator equal to zero and solve.

For example, the second question has a denominator of x-3.

x-3=0

x=3 (This is the vertical asymptote)

When you look for horizontal asymptote, you do long division.

For example, the first question [tex]f(x)=\frac{2x}{x-3}[/tex]

The answer will be 2. 2 is the quotient. You only want quotient not remainder.

y=2.

Answer:

$471.90 dollars

Step-by-step explanation:

First, we need to find out how many hours she's working.

There are 60 minutes in an hour so 15/60 is 0.25.

Thus, adding that to the 30 hours gives us 30.25.

If she makes $15.60 per hour we just multiply that by 30.25 hours and get the answer.

[tex]\frac{15.60}{hour}*30.25 hours = 471.9\\[/tex]

The [tex]\frac{}{hour}[/tex] comes from the wording of per hour, and since the unit is in the denominator, when we multiply it by the 30.25 hours, the units cancel out. Thus all we are left with is the amount of dollars made, which is $471.90.

Step-by-step explanation:

Tip: Go step-by-step

Let the number = x

Eight times the difference between a number and seven.. = 8(x-7)

is the same as... =

the number increased by 4.. x+4

8(x-7)=x+4

Distribute

8x-56=x+4

Subtract x from both sides

7x-56=4

Add 56 to both sides

7x=60

x=60/7

Answer:

Simple interest-?

Step-by-step explanation:

P= 12000

T=5yrs

R=5%

Now,

Simple interest - PTR/100

= 12000*5*5/100

= $3000

Again,

P=12000

T=3yrs

R=8%

Now,

Simple interest - PTR/100

= 12000*3*8/100

= $2880

Hope this helps.

Answer:

w= 8/7

Step-by-step explanation:

1. divide the numbers

[tex]12w-1*10=6-2w[/tex]

2. multiply the numbers

[tex]12-10=6-2w[/tex]

3. rearrange terms

[tex]12-10=-2w+6[/tex]

4. add 10 to both sides of the equation

[tex]12w-10+1-=-2w+6+10[/tex]

5. simplify

[tex]12w=-2w+16[/tex]

6. add 2w to both sides of the equation

[tex]12w+2w=-2w+16+2w[/tex]

7. simplify

[tex]14w=16[/tex]

8.divide both sides of the equation by the same term

14w/14 = 16/14

9. simplify

w = 8/7

Answer:

[tex]w = 2[/tex]

Step-by-step explanation:

[tex] \frac{(12w - 20)}{2} = 6 - 2w[/tex]

[tex]6w + \frac{ - 20}{2} = 6 - 2w[/tex]

[tex]6w + \frac{( - 10.2)}{(1.2)} = 6 - 2w[/tex]

[tex]6w + 10 = 6 - 2w[/tex]

[tex]6w - 10 + 2w = 6 - 2w + 2w[/tex]

[tex]6w + 2w - 10 = 6 - 2w + 2w[/tex]

[tex]8w - 10 = 6 - 2w + 2w[/tex]

[tex]8w - 10 = - 2w + 2w + 6[/tex]

[tex]8w - 10 = 6[/tex]

[tex]8w - 10 + 10 = 6 + 10[/tex]

[tex]8w = 6 + 10[/tex]

[tex]8w = 16[/tex]

[tex] \frac{8w}{8} = \frac{16}{8} [/tex]

[tex]w = \frac{16}{8} [/tex]

[tex]w = \frac{2.8}{1.8} [/tex]

[tex]w = 2[/tex]

3.553774

Step-by-step explanation:

[tex] \frac{2}{3} \pi {r}^{3} = 94[/tex]

h

works out to 3.553774

The radius of the hemisphere with a volume of 94 m³ is :

r = [tex]$\sqrt[3]{\frac{141}{\pi } }[/tex]

Given is hemisphere with a volume of 94 m³.

    (2/3)πr³ = 94

    πr³ = (94 x 3/2)

    πr³ = 47 x 3

    πr³ = 141

    r³ = (141/π)

    r = [tex]$\sqrt[3]{\frac{141}{\pi } }[/tex]

Therefore, the radius of the hemisphere with a volume of 94 m³ is :

r = [tex]$\sqrt[3]{\frac{141}{\pi } }[/tex]

Answer:

3/28.

Step-by-step explanation:

Total of 8 balls in the jar.

Prob (first one not green (= that its red) = 3/8

Prob ( Second one is also red) = 2/7.

So probability that both are not green = 3/8 * 2/7

= 6/56

= 3/28.

Answer:

The center of the circle is at: C=(−2,3).

The radius of the circle is r=5.

Step-by-step explanation:

A circle with center at (h,k) and a radius of r has equation (x−h)2+(y−k)2=r2.

In this example our circle equation can be written as:

(x−(−2))2+(y−3)2=(5)2

So, we have: h=−2 , k=3 and r=5.
