Problem 1

Answer: The roots are x = 0, x = 2, x = -3

------------------

Explanation:

The term "root" is another way of saying "zeros of a function" or "x intercept".

To find the roots, set each factor equal to zero and solve for x.

x-2 = 0 solves to x = 2, while x+3 = 0 solves to x = -3

========================================================

Problem 2

Answer: Roots are x = 1, [tex]x = i\sqrt{5}[/tex] and [tex]x = -i\sqrt{5}[/tex]

------------------

Explanation:

Factor by grouping

x^3 - x^2 + 5x - 5 = 0

(x^3 - x^2) + (5x - 5) = 0

x^2(x - 1) + 5(x - 1) = 0

(x^2 + 5)(x - 1) = 0

x^2 + 5 = 0 solves to the roots [tex]x = i\sqrt{5}[/tex] and [tex]x = -i\sqrt{5}[/tex]

x-1 = 0 solves to x = 1

Note: [tex]i = \sqrt{-1}[/tex]

1) Wat are the real zeros of the function y=x(x-2)(x+3):

Answer: [tex]x_{1} = -3 ; x_{2} = 0; x_{3} =2[/tex]

To find the x-intercept, set y = 0:

x( x -2 ) ( x + 3) = 0

Apply the Zero Product Property:

x - 2 = 0 or x + 3 = 0

x = 2 or x = -3

Find the union of solutions:

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

2) Find all of the solutions of the equation

x^3 -x^2 +5x - 5 = 0

Answer: x = 1 or no real solution

Apply grouping:

[tex](x^{3} -x^{2} ) + *(5x-5)=0[/tex]

Factor out common factor:

[tex]x^{2} (x-1) +5(x-1)=0[/tex]

Factor out --> [tex](x-1)(x^{2} +5) =0[/tex]

Apply zero product property:

[tex]x - 1 =0[/tex] or [tex]x^{2} +5 =0[/tex]

x - 1 = 0

Rearrange variables to the left side of the equation--> x=1 or no real solutions.

Answer:

∠ ABC = 51°

Step-by-step explanation:

the inscribed angle ABC is half the measure of its intercepted arc AC , so

5x + 11 = [tex]\frac{1}{2}[/tex] (16x - 26) ← distribute parenthesis

5x + 11 = 8x - 13 ( subtract 8x from both sides )

- 3x + 11 = - 13 ( subtract 11 from both sides )

- 3x = - 24 ( divide both sides by - 3 )

x = 8

Then

∠ ABC = 5x + 11 = 5(8) + 11 = 40 + 11 = 51°

Answer:

x = 57.8°

explanation:

[tex]\sf sin(x)= \dfrac{opposite}{hypotensue}[/tex]

[tex]\hookrightarrow \sf sin(x) = \dfrac{11}{13}[/tex]

[tex]\hookrightarrow \sf x = sin^{-1}(\dfrac{11}{13} )[/tex]

[tex]\hookrightarrow \sf x = 57.8[/tex]

Answer:

57.8° (nearest tenth)

Step-by-step explanation:

Use the sine trig ratio:

[tex]\mathsf{\sin(\theta)=\dfrac{O}{H}}[/tex]

where:

Given:

[tex]\implies \mathsf{\sin(x)=\dfrac{11}{13}}[/tex]

[tex]\implies \mathsf{x=\arcsin\dfrac{11}{13}}[/tex]

[tex]\implies \mathsf{x=57.8 \textdegree \ (nearest \ tenth)}[/tex]

The chances of selecting a pregnant guinea pig involves probability

The probability that all are pregnant is 0.187

Probabilities are used to determine the chances of events

From the question, 4 out of 7 guinea pigs are pregnant.

So, the probability that a selected guinea pig is pregnant is:

[tex]p = \frac 47[/tex]

The probability that all the selected 3 are pregnant is then calculated as:

[tex]p = \frac 47 * \frac 47 * \frac 47[/tex]

Evaluate the product

[tex]p = 0.187[/tex]

Hence, the probability that all are pregnant is 0.187

Answer:

y = -2x + 5

Step-by-step explanation:

to figure this out you may plug this equation into y = mx + b with b being the unknown

this goes to

-7 = -2(6) + b

then multiply 6 to -2

-7 = -12 + b

then add 12 to both sides

5 = b

b is 5 so that means the equation is

As per the provided information in the given question, Length of Cuboid is 25 cm . Breadth is given 20 cm . Height of Cuboid is given 15 cm . And , we have been asked to calculate the Volume of Cuboid .

For calculating the Volume , we will use Formula :-

[tex] \bigstar \: \: \boxed {\sf { \: Volume \: _{Cuboid} = Length \times Breadth \times Height \: }} [/tex]

Therefore , by Substituting the given values in the above Formula :-

⇒ Volume = Length × Breadth × Height

⇒ Volume = 25 × 20 × 15

⇒ Volume = 500 × 15

⇒ Volume = 7500

Hence :-

[tex] \underline {\rule {210pt} {4pt}} [/tex]

⇒ Volume = Length × Breadth × Height

⇒ Volume = 25 × 20 × 15

⇒ Volume = 500 × 15

Answer:

(-1,1)

Step-by-step explanation:

Answer:

(- 1, 1 )

Step-by-step explanation:

2x - 3y = - 5 → (1)

3x + y = - 2 → (2)

multiplying (2) by 3 and adding to (1) will eliminate y

9x + 3y = - 6 → (3)

add (1) and (3) term by term to eliminate y

11x + 0 = - 11

11x = - 11 ( divide both sides by 11 )

x = - 1

substitute x = - 1 into either of the 2 equations and solve for x

substituting into (2)

3(- 1) + y = - 2

- 3 + y = - 2 ( add 3 to both sides )

y = 1

solution is (- 1, 1 )

» Variables y and x have a proportional relationship, where y = 9 when x = 3. What is the value of x when y = 36? Enter your answer in the box.

— — — — — — — — — —

Since variables y and x have a proportional relationship, then the equation is in the form y=kx.

First, we need to find the constant of variation (k) by substituting the given to the equation of variation.

The constant of variation (k) is 3. So, find the value of x when y = 36.

Hence the unknown value (x) is 12.

To help Carmen find the total after 3 years

We'll have to use the annual compound interest formula: A = P(1 + r)ⁿ

A = Final balance (?)

P = Principal balance (6000)

r = Rate (0.028)

n = years (3)

A = 6000(1 + 0.028)³

A = 6000(1.028)³

A = 6000(1.086373952)

A = 6518.243712

Round that to the nearest cent, and we get $6,518.24 as the answer.

Step-by-step explanation:

The formula to find the volume of right circular cylinder is: V=πr^2*h

We know the following info:

V = 5390m^3

So the equation would be 5390 = 3.14*7^2*h

so h = 35m

Answer:

h ≈ 35.01m

Step-by-step explanation:

V=Лr²h

r =7m

v = 5390³

h= V / Лr²

Answer:

One solution

(2,0) is the point

Step-by-step explanation:

If the graphs of the equations intersect, then there is one solution that is true for both equations.

When the lines intersect, the point of intersection is the only point that the two graphs have in common, so the coordinates of that point are the solution for the two variables used in the equations.

The point of intersection is (2,0), because that is the point that both lines intersect at.

The graph looks like an absolute function.

If we were to compare the function [tex]y= |x|[/tex] to this graph (see image attached), we see that the function in the graph has only shifted two to the right.

To write in function form, when shifting the graph horizontally

In this case, since we want to shift over two spots horizontally, we get the function is

 y = |x -2|

Now we want to find the function that is increasing and decreasing over the same interval.

The only function that looks the most similar is y = 4|x-2|.

The reason for that is because the y = 4|x-2| is just a stretched version of y= |x-2| meaning the point where it is increasing or decreasing should stay the same. Look at the second image I attached.
