Answer:

By Ensure that its angles are identical, and also ensure that circle's diameter is only smaller than the square because then the circle diameter multiplies the range by 2, so how you can find the  formula of the radius over

The building process is as follows:

Circle diameter is plotted.

The method as described in the perfectly straight central axis of a portion is drawn by the bisector of the right angle of the radius.

It is also a circular pattern diameter.

The four areas on the circle that result are indeed the square vertices.

Answer:

K = -2J + 28

Step-by-step explanation:

To find the slope just look at rise over run.

The rise is -4 as it goes down and run is 2 to the right.

slope = rise/run = -4/2 = -2

The second blank is 28, you just have to see where the line touches the y axis.

We have given that,

Karen created a sample of 20 students from a population of 100 in the following way.

First, she gave each student a unique number from 1 to 100. She then obtained a list of 20 randomly generated numbers between 1 and 100.

She used these numbers to identify which students to select. Here is the list of random numbers.

We have to determine the three students are part of her sample.

Answer:

d = 90°

e = 41°

f = 139°

Step-by-step explanation:

d + 90° = 180° (Angles in linear pair)

-> d = 180° - 90°

-> d = 90°

e = 41° (vertical angles)

f + 41° = 180° (Angles in linear pair)

-> f = 180° - 41°

-> f = 139°

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:

∠ 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:

Volume = height x width x lengthV = h•l•w(50x - 2x3) = (2x)•(x+5)•w(50x - 2x3) = (2x2 + 10x)•w(50x - 2x3)/(2x2 + 10x) = w2x(25 - x2)/(2x(x + 5)) = w(25 - x2)/(x + 5) = w(5 + x)(5 - x)/(x + 5) =w

Answer: When triangles have two pairs of corresponding angles that are congruent, those triangles are similar.

Step-by-step explanation:

Answer:

The volume of the composite figure is approximately 337.27 m³

Step-by-step explanation:

The given parameters are;

The length of the cylinder, L = 15 meters

The diameter of the cylinder, D = 7 meters

The base length of the square prism, B = 4 meters

We note that the square diagonal of the square = √(4² + 4²) = 4·√2 ≈ 5.66 meters, fits in the cylinder

Therefore, we have;

The volume of the composite figure = The volume of the cylinder - The volume of the square prism

The volume of the cylinder = π/4 × D² × L = π/4 × 7² × 15 ≈ 577.27 m³

The volume of the square prism = B² × L = 4² × 15 = 240 m³

∴ The volume of the composite figure ≈ 577.27 m³ - 240 m³ ≈ 337.27 m³

The volume of the composite figure ≈ 337.27 m³.

Answer:

from the lines i you can see that these triangles are the same so that means the other angle is 74 so since we know that the angles of a triangle always add up to 180

5x+3x+2+74=180

The similar triangles ABC and DEF may or may not have equal lengths

Janette's claim that triangles ABC and DEF are similar triangle is true

Start by calculating the length of the third sides using the Pythagoras theorem.

[tex]a^2 = b^c + c^2[/tex]

For triangle ABC, we have:

[tex]AC^2 = 20^2 + 21^2[/tex]

[tex]AC = 29[/tex]

For triangle DEF, we have:

[tex]58^2 = 40^2 + EF^2[/tex]

This gives

[tex]EF^2 = 58^2 - 40^2[/tex]

[tex]EF = 42[/tex]

So, we have the following corresponding lengths on both triangles

Triangle ABC             Triangle DEF               Common ratio

20                                      40                                    2

21                                       42                                    2

29                                      58                                    2

Since the common ratios are the same, then the triangles are similar

Hence, Janette's claim is true

Answer:

35m

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

r = 7m

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

h= 5390 / Л7²

=35.01409m

0.2588(x) = 7

Then, divide both sides by 0.2588

x = 27.048

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:

(-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 )
