Answer: B

Step-by-step explanation:

They substitute =AC for =12 from step 1.

Answer:

it is more intense by 3.0

Step-by-step explanation:

Answer:

Let A represent the center of the circle. Let the point B be a point at the intersection of the one end of the chord and the edge of the circle. Finally, let C represent a point between the center of the circle and the midpoint of the cord. The triangle ABC is a right triangle with a 90 degree angle at ACB. Since the cord length is 30, the bisected segment BC is length 15 .

(length AB)^2 = (length BC)^2 + (length AC)^2

17^2 = 15^2 + (length AC)^2

289 = 225 + (length AC)^2

add -225 to each side

64 = (length AC)^2

take square root of each side

8 = length AC

Answer: 68 degrees

Step-by-step explanation:

Let the measure of the angle be x.

The supplement of the angle is 180 - x as supplementary angles add up to 180 degrees.

The complement of the angle is 90 - x as complementary angles add up to 90 degrees.

We can set up an equation.

180 - x = 46 + 3*(90-x)

180 - x = 46 + 270 - 3x

Combine like terms:

2x = 136

Divide both sides by 2:

x = 68

What are supplementary and complementary angles?

The supplement of an angle (180 - x) is [=] 46 more than 3 times the complement (90-x):

180 - x = 3 (90 - x) +46

Now, solve for x:

180 - x = 3 (90 - x) +46

180 - x = 270 - 3x +46

180 - x = 316 -3x

-x = 136 -3x

2x = 136

x = 68

The angle is 68°

Answer:

It would not be any of those answers. it would be 106 :) Its negative numbers divided

The value of expression is,

⇒ - 27 / 79

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The expression is,

⇒ 27 ÷ (- 34 - 45)

Now, We can simplify as;

⇒ 27 ÷ (- 34 - 45)

⇒ 27 ÷ - 79

⇒ - 27 / 79

Thus, After simplification, we get;

⇒ - 27 / 79

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

just replace x with the highest value

f([tex]x_{max}[/tex]) = 3(2) + 2

= 8

The greatest value in the range of f(x) is 8.

The domain of a function is defined as the set of all the possible input values that are valid for the given function.

The range of a function is defined as the set of all the possible output values that are valid for the given function.

WE are given that the domain for f(x) = 3x + 2 is -3 ≤ x ≤ 2.

We just need to replace x with the highest value;

f(2) = 3(2) + 2

f(2) = 8

Therefore, The greatest value in the range of f(x) is 8.

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.

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:

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
