Answers

Answer 1

Answer: 9 : 45 = 3 : 15 = 1 : 5
19 : 38 = 1 : 2
24 : 40 = 12 : 20 = 6 : 10 = 3 : 5
14 : 28 = 1 : 2
8 : 20 = 4 : 10 = 2 : 5
15 : 20 = 3 : 4
9 : 15 = 3 : 5
19 : 180 = 19 : 180
18 : 27 = 6 : 9 = 2 : 3
36 : 60 = 18 : 30 = 9 : 15 = 3 : 5
12 : 30 = 4 : 10 = 2 : 5
32 : 54 = 16 : 27
13 : 65 = 1 : 5
12 : 15 = 4 : 5
12 : 20 = 6 : 10 = 3 : 5

Describe the graph of the function f(x) = x3 − 15x2 + 68x − 96. Include the y-intercept, x-intercepts, and the end behavior.

Answers

in the form
f(x)= $ax^(n)+bx^(n-1)...+z$
a=leading term,
z=contstant aka y intercept

this is 3rd degree (highest term is x^3) with leading term positive so the graph goes from bottom left to top right
x intercept is when y=0 so
0=x^3-15x^2+68x-96
factor
(x-8)(x-4)(x-3)
these are your roots aka zeroes (where the line crosses the x axis)
the roots are
(x-r) where r=root aka x intercept

so we have
(x-8)(x-4)(x-3)
roots are
8,4,3
x intercepts are 8,4,3 or (8,0),(4,0),(3,0)

y intercept is when x=0 so just get rid of all x terms and we are left with
-96
aka y intercept=(0,-96)

x intercepts=(8,0),(4,0),(3,0)
y intercept=(0,-96)
end bhavior is graph goes from bottom left to top right

Multiply a number by six and then subtract negative 10 the different is negative Forty-Four. What is the number.Thank you

Answers

Let the number be x

According to your question,

6x - (-10) = -44

6x+10 = -44

6x = -54

thus, x = -54/6 = -9

Thus, x = -9

Thus, the number is -9

What are the zeros of j(x) in the polynomial equation?

Answers

Answer: x = $(-3)/(2)$ , 0, $(3)/(2)$

Step-by-step explanation:

To find the zeros, we will find the solutions to this equation that make it equal 0. This is a cubic function, so we can assume that there will be three solutions.

Given:

$\displaystyle J(x) = (12x^3)/(5) -(27x)/(5)$

Set the functionequal to 0:

$\displaystyle 0 = (12x^3)/(5) -(27x)/(5)$

Subtract:

$\displaystyle 0 = (12x^3-27x)/(5)$

Multiply both sides of the equation by 5:

$\displaystyle 0 = 12x^3-27x$

Factor the polynomial:

$\displaystyle 0 = (3x)(2x-3)(2x+3)$

Solve with the zero product property:

0 = 3x 0 = 2x - 3 0 = 2x + 3

0 = x 3 = 2x -3 = 2x

x = 0 x = $(3)/(2)$ x = $(-3)/(2)$

The formula a= bf-v1 is used to calculate acceleration as the change in velocity over a period of time. Solve the formula for the final velocity, bf in terms of initial velocity, v1, acceleration, a, and time,

Answers

Answer:

The formula for the final velocity, bf in terms of initial velocity, v1, acceleration, a, and time is given as

$bf=v1+a* t$

Step-by-step explanation:

Given:

$a=(bf-v1)/(t)$

To Find:

bf = ?

Solution:

Acceleration:

Acceleration is defined as the ratio between the change in velocity of an object and the time it takes for the object to change the velocity.

In formula, this is written as:

$a=(v_(f)-v_(i))/(t)$

Where,

'a' is the Acceleration.

'vf' is the final velocity.

'vi' is the initial velocity.

't' is the time it takes for the object to accelerate from vf to vi

Here it is given as

$a=(bf-v1)/(t)$

So,

Where,

'a' is the Acceleration

'bf' is the final velocity.

'v1' is the initial velocity.

't' is the time it takes for the object to accelerate from bf to v1.

On Solving the above equation 'bf' we get

$a=(bf-v1)/(t)\n\na* t=bf-v1\n\nbf=v1+a* t$ ....As required

Final answer:

In physics, the formula bf = a + v1 is used to calculate the final velocity in terms of the initial velocity, acceleration, and time. If acceleration is zero, final and initial velocities are equal, pointing to constant velocity. If acceleration is negative, the final velocity is less than the initial, indicating deceleration.

Explanation:

The equation a = bf - v1 is used to calculate acceleration, defined as the change in velocity over a period of time. To solve for the final velocity, bf, we simply need to rearrange the equation.

So, bf = a + v1. This equation tells us that the final velocity is equal to the sum of the initial velocity and the acceleration.

Other insights we can gather from this equation include: if acceleration is zero, the final and initial velocities are equal, pointing to constant velocity. This is because there's no change in speed. Conversely, if acceleration is negative, the final velocity is less than the initial, indicating a decrease in speed or deceleration.

By what fraction name for 1 must 2/3 be multiplied to form a fraction with a denominator of 15

Answers

If you are asking what I think than it should be 5/5 because 3*5=15 so in that case the denominator would be 15 making the whole answer 10/15 although that could still be simplified to 2/3) (that's what happens when you multiply by one)

Or you may be asking 1/x forms a denominator of 15.
In this case you would still have 5 as your number (or really 1/5), if would just mean when they are multiplied together you would get 2/15 instead....
