Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3y + 2x = 1 into this form

Subtract 2x from both sides

3y = - 2x + 1 ( divide all terms by 3 )

y = - [tex]\frac{2}{3}[/tex] x + [tex]\frac{1}{3}[/tex] ← in slope- intercept form

with slope m = - [tex]\frac{2}{3}[/tex] → A

By rearranging the equation 3y + 2x = 1 into slope-intercept form, y = mx + b, we find that the slope of the line is -2/3. The correct answer is A.) -2/3.

The slope of the line whose equation is 3y + 2x = 1 is found by solving for y to get the line into slope-intercept form, which is y = mx + b, where m represents the slope.

Now that the equation is in slope-intercept form, we can see that the slope m is -2/3. Therefore, the correct answer is A.) -2/3.

Answer:

ANSWER

The area of the base is 14.5π in²

EXPLANATION

The volume of a cylinder is given by

[tex]Volume =base\:area \times height[/tex]

Or

V=Bh

It was given that the volume of the cylinder is 174π in³.

The height was given as 12 inches.

We substitute to get,

174π=12B

Divide both sides by 12 to get:

B=14.5π in²

Hence the area of the base is 14.5π in²

Answer:

14.5

Step-by-step explanation:

12%*14000*3

Which is 5040

Therefore, it will have to pay back $4050

J.T. will pay back a total of $18,480 altogether.

To calculate the total amount J.T. will pay back, we can use the formula for simple interest:

[tex]\[I = P \times r \times t\][/tex]

Where:

- (I) = Interest

- (P\) = Principal amount (the initial loan amount)

- (r) = Annual interest rate (in decimal form)

- (t) = Time (in years)

Given that J.T. borrows $14,000 at an annual interest rate of 12% for 3 years, we can plug these values into the formula:

[tex][I = 14000 \times 0.12 \times 3\][/tex]

[I = 5040]

So, the total interest J.T. will pay is $5,040.

To find the total amount J.T. will pay back, we add the interest to the principal:

[Total amount = Principal + Interest]

[Total amount = 14000 + 5040]

[Total amount = 18440]

Therefore, J.T. will pay back a total of $18,480 altogether.

In summary, by using the formula for simple interest, we determined the interest amount J.T. will pay over the 3-year period, and then added it to the principal amount to find the total repayment amount.

Complete question:

A bank offers a home improvement loan with simple interest at an annual rate of 12%. J.T. borrows an amount of $14,000 to pay back over 3 years. How much will he pay back altogether? Explain how you found the total amount.

Answer:

The solution to the equation 1/4 x = 5 is '' x = 20''

Step-by-step explanation:

you take ''1/4'' and multiply it by ''20'' and the answer you'll get is ''5''

The solution to the equation 1 / 4 x = 5 is found by isolating x. After multiplying both sides of the equation by 4, you find that x = 20.

The solution to your equation, 1 / 4 x = 5, can be found using the principles of algebra. This equation is asking us 'What value of x can I multiply by 1/4 to equal 5?'

The best way to find the solution is to isolate x on one side of the equation. In this case, you'll start by multiplying both sides of the equation by 4. Now your equation looks like this:

1/4 x * 4 = 5 * 4

Simplifying the equation, you'll get:

x = 20

Therefore, you can see that the solution to the equation 1/4 x = 5 is x = 20.

Hello!

The answer is: 17 ft.

Explanation:

To find this out, just divide the perimeter, and the amount of sides in a triangle, which is 3. This will only work with equilateral triangles because an equilateral triangle has all three sides the same length. Anyway, divide 51 and 3. (51 / 3 = 17) Just to make sure, you can add three 17's together, 17 + 17 + 17 = 51, the perimeter.

I hope this helped! ~Q

The length of one of side of Equilateral Triangle is 17 feet, whose perimeter is 51 feet.

An equilateral triangle's perimeter is the sum of its three sides. P = 3a.

'a' is the side of equilateral triangle.

Given that:

Perimeter of Equilateral Triangle = 51 feet

where 'a' is the side of equilateral Triangle.

As we know that all side of equilateral triangle are equal.

So, its all sides measure 'a'.

Perimeter = a +a +a

51= 3a

a= 51/3

a=17 feet.

Hence, the side of equilateral triangle measures 17 feet.

The correct answer between all

the choices given is the first choice or letter A. I am hoping that this answer

Step-by-step explanation:

Since we have given that

A be the event that Ashley drives faster than the speed limit.

P(A)=0.34

B be the event that he gets a speeding ticket.

P(B)=0.22

Probability that he drives faster than the speed limit, given that he has gotten a speeding ticket i.e.

but for A and B to be independent ,

P(A).P(B)= P(A and B)

0.34×0.22=0.0748

Answer:

t = 0.722 seconds

Step-by-step explanation:

Given in the question that an equation

h = -16t² + 6t + 4

here h is the height

        t is the time

To solve this question we need to substitute height with zero because at ground level height is zero

0 = -16t² + 6t + 4

a = -16

b = 6

c = 4

Formula to use

t = -b±√(b²-4ac) / 2a

Plug values in the formula

t = -6 ± √36-4(-16)(4) / 2(-16)

t =  6±2√73 / 32

t =  6+2√73 / 32 or t =  6-2√73 / 32

t = 0.722 or t = -0.347

since time can't be in negative so we reject  t = -0.347

Answer:

The base of the exponential function is 0.5 which is between 0 and 1 and thus this is an exponential decay function.

Step-by-step explanation:

Exponential equations are usually in the form;

[tex]y=ab^{x}[/tex]

where;

a is the initial value, that is the value of y when x is 0,

b is the growth or decay factor and also the base of the exponential function

If b>1, then it is an exponential growth function and the values of y keep getting bigger.

if 0<b<1, then it is an exponential decay function and the y values keep getting smaller as x increases.

In the function given;

[tex]y=(\frac{1}{2})^{x}[/tex]

The base of the exponential function is 0.5 which is between 0 and 1 and thus this is an exponential decay function.

In order to justify our prediction, we can simply obtain the graph of the function and check on how x and y vary.

From the attachment below we can see that the values of y become increasingly smaller as the values of x increases in magnitude which justifies our predictions.

The function y = [tex](1/2)^x[/tex] represents an exponential decay because the base (1/2) is a fraction less than 1.

The function y = [tex](1/2)^x[/tex] represents an exponential decay model because it is in the form y = [tex]a^x[/tex] where a is a fraction between 0 and 1 (0 < a < 1).

An exponential decay function describes a situation where the quantity decreases over time, and the rate of decrease slows down as the quantity gets smaller.

In contrast, if a were greater than 1, it would represent exponential growth, indicating that the quantity increases over time, and the rate of increase accelerates as the quantity grows larger.

So, since (1/2) is less than 1, the function shows exponential decay.

Step-by-step explanation:

Given

8x² + 10x + 2 ← factor out 2 from each term

= 2(4x² + 5x + 1)

To factor the quadratic

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 4 × 1 = 4 and sum = + 5

The factors are + 1 and + 4

Use these factors to split the x - term

4x² + x + 4x + 1 ( factor the first/second and third/fourth terms )

= x(4x + 1) + 1 (4x + 1) ← factor out (4x + 1)

= (4x + 1)(x + 1), thus

4x² + 5x + 1 = (4x + 1)(x + 1) and

Answer:

Step-by-step explanation: first, find y by itself by adding 2x to the other side then diving by the 5y to get y=2/5x +2! Rise 2, run 5 from your start at positive 2 on the graph and you should get line a!!!

The graph of the equation -2x + 5y = 10 has a positive slope of 2/5 and a y-intercept of 2. None of the provided options accurately describe the graph of the equation, as they indicate incorrect y-intercept values and describe the slope incorrectly.

To find which line is a graph of the equation -2x + 5y = 10, we need to identify the slope and the y-intercept of the line. To do this, we should rearrange the equation into slope-intercept form, which is y = mx + b where m is the slope and b is the y-intercept.

Rearranging the equation, we get:

5y = 2x + 10

y = (2/5)x + 2

The slope is the coefficient of x, which is 2/5, and the y-intercept is the constant term, which is 2. The line has a positive slope, and based on the slope-intercept form, it rises on the graph as the x-value increases. Therefore, option d with a positive slope and a y-intercept of 50 must have a typo since our y-intercept is 2. The correct interpretation would be that the line gradually moves upward on the graph as the x-value increases, thanks to its positive slope.

Hence, none of the provided options describe the graph of the equation -2x + 5y = 10 accurately because the y-intercept should be 2, not 50, and the slope is positive. Keep in mind that a positive slope results in an upward, not a downward, trend as x increases.

x = - 3 with multiplicity 2

Step-by-step explanation:

f(x) = (x - 3)(x + 3)(x + 3) = (x - 3)(x + 3)²

Equating each factor to zero and solving for x

x - 3 = 0 ⇒ x = 3 with multiplicity 1

x + 3 = 0 ⇒ x = - 3

x + 3 = 0 ⇒ x = -3

Thus x = - 3 has multiplicity of 2

The fact that the factor is squared gives the multiplicity

(x + 3)³ has root - 3 of multiplicity 3

Answer:

Assuming that Seiki wants to be as close to 40 minutes are possible (to the nearest minute), She would want to spend 7 minutes on each of the 3 cardio machines

Step-by-step explanation:

With Seiki wanting to spend at least 40 minutes exercising and spending 20 minutes lifting weights, she needs to spend at least 20 more minutes on her cardio. If we are looking for a number that is divisible by 3, that would mean that she would spend 21 minutes exercising.

Seiki should spend at least 10 minutes on each cardio machine after her 20-minute weightlifting session to meet continuous exercise and weekly cumulative goals, therefore surpassing her minimum of 40 minutes of exercise and aligning with health recommendations.

Time Allocation For Cardio Machines

Seiki wants to spend more than 40 minutes exercising, with 20 minutes devoted to lifting weights and the rest on three different cardio machines. To calculate the time she should spend on each cardio machine, we first deduct the weightlifting time from the total minimum exercise time.

This leaves us with more than 20 minutes for cardio (40 minutes total - 20 minutes of weights = 20+ minutes for cardio).

Since she wants to spend the same amount of time on each machine, we divide the remaining time by three. Let's assume Seiki decides on the minimum of 21 minutes for cardio to exceed the 40 minutes total.

So, 21 minutes divided by three cardio machines equals seven minutes per machine.

However, to align with the recommendations for sessions to be continuous for 10 minutes or more and the goal of a cumulative total of 150-300 minutes from at least three days a week, Seiki should aim for at least 10 minutes on each machine.

This would translate to at least a total of 30 minutes on cardio machines, bringing her workout to a minimum of 50 minutes (20 minutes of weights + 30 minutes of cardio).

Remember, these calculations are based on the minimum requirements, and Seiki can adjust her workout duration on the cardio machines to suit her fitness goals and available time.
