Question 1:
Write the specific equation for the kinetic energy E (measured
in Joules) of an 1100-kg car. Use this equation to compare the kinetic
energy of an 1100-kg car moving at a velocity of 10 meters per second to
the kinetic energy of the same car moving at 3 times the velocity.

Answers

Answer 1

Answer:

Step-by-step explanation:

KE = ½mv²

KE₁₀ = ½(1100)10² = 55000 = 55 kJ

KE₃₀ = ½(1100)30² = 495000 = 495 kJ

9 times greater

kia worked 30 hours and 15 minutes this weekend . if she makes $15.60 per hours ,how much did she make?

Answers

$471.90

30 x 15.60 = 468 (total full hours x amount per hour)
60 / 15 = 1/4 (60 minutes per hour divided by the 15 minutes they worked = amount of the hour)
15.60 x 1/4 = 3.9 (amount for the 15 minutes worked)
468 + 3.9 = 471.9 (total full hours + 15 minutes total)

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.

Graphing Asymptotes for Rational Functions

Two copies of the same Rational Functions are shown below.

On the graph on the left, draw the Horizontal Asymptote and write the equation for the horizontal asymptote underneath.

On the graph on the right, draw the Vertical Asymptote and write the equation for the Vertical Asymptote underneath.

Answers

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.

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

What is the radius of a hemisphere with a volume of 94 m", to the nearest tenth of a

meter?

Answers

Answer:

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]

What is a hemisphere? What is a mathematical function, equation and expression?               hemisphere : a hemisphere is half of a sphere.function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.

Given is hemisphere with a volume of 94 m³.

The volume of sphere is : V{S} = (4/3)πr³.So, the volume of hemisphere will be : V{S}/2 = V{H} = (2/3)πr³.So, we can write as :

    (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]

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]
