12.x^3 when x =-3

pls helppp step by step

Answers

Answer 1

Answer:

11) 14

12) -27

Step-by-step explanation:

11-a when a=-3

Plug in -3 into the equation

11-(-3)

A negative times a negative becomes a positive

So the equation becomes 11+3

Answer is 14

x³ when x=-3

Plug in -3 into the equation

-3³

Solve, which should give you -27

Savannah loves to talk on her cell phone. She has $100 in her budget to pay this month’s cell phone bill. Her cell phone plan is $20 per month plus $0.10 per minute of usage. If x represents the minutes of usage, which equation best represents the word problem?
A. 100+20=.10x
B. 100+.10x=20
C. 20 +.10x=100
D. 20-.10x= 100

Answers

Answer: C. best fits the word problem.

Step-by-step explanation:

The reason C. best fits is because the bare minimum $20 she has to pay plus .10 times whatever amount of minute's she spends talking has to equal $100 for her to stay in budget. A good example would be say she spends 800 minutes in total on her phone. 0.10 times 800 is 80. So in this hypothetical situation, it would be 20 + 80 = 100.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Point S is between points R and T on RT.

RS = 2x - 8

ST = 3x - 10

RT = 17

From the above information:

RT = RS + ST

17 = 2x - 8 + 3x - 10

17 = 5x - 18

35 = 5x

x = 35/5

x = 7

RS = 2x - 8 = 2(7) - 8 = 6 units

ST = 3x - 10 = 3(7) - 10 = 11 units

RT = 17 units

Thus, the value of x is 7 and the measure of the line segment RS is 6 units, ST = 11 units, and RT = 11 units.

Step-by-step explanation:

Jada is planning a kayak trip. She finds an expression for the time, T(s), in hours it takes her to paddle 10 kilometers upstream in terms of s, the speed of the current in kilometers per hour. This is the graph Jada gets if she allows s to take on any value between 0 and 7.5. What would be a more appropriate domain for Jada to use instead?

Answers

Answer:

A more appropriate domain would be all real numbers except x = 5.5

Step-by-step explanation:

Given that the domain of a rational function consists of the set of real numbers but excluding those real numbers that results in a zero in the denominator

The given graph of the function has a vertical asymptote at s = 5.5 which indicates a value for which the function is not defined and at x = 5.5, and as such the value (5.5) of the asymptote is not a member of the function's domain

The values of the domain of a function consisting of a reciprocal must exclude does that result in a zero denominator.

The domain of the function that represents Jada's trip is the set of input value the function can take

The appropriate domain is: all real numbers except x = 5.5

From the graph, we can see that:

The x-value starts at negative infinity, and ends near 5.5The x-value then continues near 5.5, and ends at positive infinity

This means that the input of the graph cannot be 5.5

Hence, an appropriate domain would be: [tex]\mathbf{x \ne 5.5}[/tex]

Answers

Answer: 8

1.25 days would be taken for 3 men to complete the same job.

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that 12 men 5 days to complete a job

We have to find for how many days three men can complete the same job.

Let x be the time taken by 3 men to complete the job.

Formulate a proportional equation.

12/5=3/x

Apply cross multiplication

12x=15

Divide both sides by 12

x=15/12

both 15 and 12 are multiples of 3

x=5/4

x=1.25

Hence, 1.25 days would be taken for 3 men to complete the same job.

The circumference of a circle is 10 inches. What is its area in square inches?

Answers

Answer:

7.96 square inches.

Step-by-step explanation:

Area of a circle given a circumference is given by formula:

[tex]A = \frac{C^{2}}{4\pi}[/tex]

So substituting into equation we have: [tex]C= 10[/tex].

Therefore [tex]A = 10^{2}/4\pi = 100/4\pi=25/\pi =7.96[/tex] square inches.

The area of the circle is 7.96 square inches if the circumference of a circle is 10 inches.

What is a circle?

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

It is given that:

The circumference of a circle is 10 inches.

As we know the circumference of a circle is given by:

C = 2πr

C is the circumference of the circle.

r is the radius of the circle.

10 = 2πr

r = 5/π inches

As we know,

The area of the circle is given by:

A = πr²

Here, A represents the area of the circle.

Plug the value of the radius r in the above formula:

A = π(5/π)²

A = 25/π square inches

Take π = 3.14

A = 25/3.14

A = 7.96 sqaure inches

Thus, the area of the circle is 7.96 square inches if the circumference of a circle is 10 inches.

Answers

Answer:

y = 12

x = 10/3

Step-by-step explanation:

y = -3.6x + 12

From this equation, which is in slope intercept form (y = mx+b), we already know that b represents the y-intercept, so that means the y-intercept is 12.

To find the x-intercept, we need to make y equal 0 to find x. So:

0 = -3.6x + 12

-3.6x = -12

x = 3.33333 --> 3 1/3

x = 10/3

Answer:
x-intercept: 10/3
y-intercept: 12

Steps:
Finding x
y=-3.6x+12
0= -3.6x+12
3.6x=12
x=10/3

Finding y
y=-3.6x+12
y=-3.6(0)+12
y=12

Hello!! I need help with square root please help me!!!

Answers

Ok so what you need to do is you need to get all the numbers and see which one is the right number so...

A. y = 11.2 that is wrong

B. y = 25 is wrong

C. y = 5 is right

D. y = 15 is wrong.

C is right because it would be 5 times 5 times 5. SO 5 times 5 is 25, and then u times it by 5 and you get 125!

C is correct

Hope this helps!!

Answer:

This is actually a cube root, since you need a cube root to cancel out the cube.

C, y = 5

Step-by-step explanation:

125 = 5 × 5 × 5 = 5^3

5 × 5 × 5 = 25 × 5 = 125.

Therefore the cube root of 125 = 5.

It REALLY helps when you break these into factors.

[tex] \sqrt[3]{125} = 5 , \: as \: {5}^{3} \: = 125 [/tex]

This is essentially asking what multiplied by itself three times is equal to 125.

Process of elimination can be used for any number cubed that is ≠ 125

i.e : 11.2^3 ≠ 125

11.2^3 = 11.2 × 11.2 × 11.2 = (11.2-1.2)(11.2+1.2)(11.2) = (11.2)((10)(12.4) + 1.2^2) = 124 + 1.44 = (125.44)(11.2) = 125.44(10+1+(2/10)) = 1254.4 + 125.44 + 25.088 = 1404.928 ≠ 125, y ≠ 11.2

I.e : 25^3 = 25 × 25 × 25 = 625 × 25 = (600+25)(25) = 625 + 6(25)(100) = 15000 + 625 = 15625 ≠ 125, y ≠ 25.

And i.e: 15^3 = 15 × 15 × 15 = 225 × 15 = (225)(10+5) = 225(10) + 225(10/2) = 2250 + 2250/2 = 2250 + 1125 = 3375 ≠ 125, y ≠ 15.
