What’s the correct answer answer asap for brainlist

Given the equation

Then

The Correct answer is

Option D 6

The Radius is 15.27 cm and the the Diameter is 30.55 cm

Given

Circumference = 96cm

Circumference is the total arc length of a circle or it is simply the perimeter of a circle.

The formula for circumference is 2πr

where π = Ratio of circumference to the diameter of a circle

π = 3.14

r = Radius of the circle

Substituting the value in the formula we get

2πr = 96 cm

πr = 48 cm

r = 15.27 cm

Diameter (d)  = 2 × r

hence        d = 2 × 15.27 cm

                 d = 30.55 cm

Hence the radius = 15.7cm

Diameter = 30.55 cm

The equation of the line which passes through point (-5,20), with a slope of -3 is y = -3x + 5.

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Given the data in the question;

Point ( -5,20 )

First, we find the y-intercept 'b', by plug the slope m ( -3 ) and point  ( -5,20 ) into the equation of line formula and solving for b.

y = mx + b

20 = (-3)(-5) + b

20 = 15 + b

b = 20 - 15

b = 5

Now that both the slope m and y-intercept b is known, plug these into y = mx + b to determine the equation of the line.

y = (-3)x + 5

y = -3x + 5

Therefore, the linear equation of the line is y = -3x + 5.

Side a and Side b

Since both triangles are similar, the corresponding sides will be proportional.

To solve for the length of side a, apply the proportionality equation:

Plug in values and solve for a:

Thereofore, the length of side a = 16

To solve for the length of side b, apply the equation:

Plug in the values for the variables and solve for b:

The length of b is 21.3

ANSWER:

• a = 16

• b = 21.3

Answer:

C    x = 5

Step-by-step explanation:

4x - 3 = 12 + x

Add 3 on both sides:
4x - 3 + 3 = 12 + 3 + x

4x = 15 + x

Subtract x from both sides:
4x - x = 15 + x - x

3x = 15

x = 15/3

or

x = 5

Answer:

[tex]4x - 3 = 12 + x \\ \\ ➪4x - x = 12 + 3 \\ \\ ➪3x = 15 \\ \\ ➪x = \frac{15}{3} = 5[/tex]

C] x = 5 Is ᴛʜᴇ ʀɪɢʜᴛ ᴀɴsᴡᴇʀ.

To solve the question, we will follow the steps below:

To find f(f(x)), we will simply replace x by x² - 1 in the function x² - 1

That is:

f((fx)) = (x²-1)² - 1

Then we open the parenthesis

f(f(x)) = (x² - 1)(x² -1) - 1

=x²(x²-1)-1(x²-1) - 1

= x⁴ - x² - x² + 1 - 1

= x⁴ - 2x²

So the correct option is option D. which is x⁴ - 2x²

The answer is 2 m = -4 / -2 = -2 / -1 = 2

Answer:

Step-by-step explanation:

Bharat can type words in lengths of time as 100 words, 600 words, and 460 words in 5 minutes, 30 minutes, and 23 minutes respectively.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 12×2 = 24

Bharat types 20 words per minute which are given in the question.

To determine the number of words can he type in each length of time

We have to multiply the time by his typing speed.

The number of words that can be typed by Bharat in 5 minutes :

⇒ 20 × 5

⇒ 100

The number of words that can be typed by Bharat in 30 minutes :

⇒ 20 × 30

⇒ 600

The number of words that can be typed by Bharat in 23 minutes :

⇒ 20 × 23

⇒ 460

Therefore, He can type words in lengths of time as 100 words, 600 words, and 460 words in 5 minutes, 30 minutes, and 23 minutes respectively.

Answer: nonlinear function

Step-by-step explanation:

The rate at which y increases is not constant with respect to x.

The probability that, in any hour, exactly 5 cars will enter the car wash is P(x = 5) = 0.0920.

This can be modeled as a Poisson random variable.

The mean rate is the parameter of the Poisson distribution:

λ = 4 cars/30 mins

λ = 8 cars/hr

The probability that exactly k cars will enter the car wash can be calculated as:

P(x = k) = ([tex]8^{k}[/tex] × [tex]e^{-8}[/tex]) ÷ k!

Then, the probability that exactly 5 cars will enter the car wash for k=5 is:

P(5) = ([tex]8^{5}[/tex] × [tex]e^{-8}[/tex]) ÷ 5!

P(5) = (32768 × 0.0003) ÷ 120

P(5) = 0.0920

Answer:

a/c

Step-by-step explanation:

Sine is always the side opposite the angle and the hypotenuse

Answer:

[tex]\large \text{Second Choice: $\dfrac{a}{c}$}[/tex]

Step-by-step explanation:

For any given triangle, the Law Of Sines states that the ratio of each side to the sine of the angle opposite that side is the same

So we have
[tex]\dfrac{a}{\sin \angle F} = \dfrac{c}{\sin \angle 90} = \dfrac{b}{\sin \angle G} \\\\[/tex]

[tex]\sin \angle 90 = 1[/tex]

So we get from the first two ratio equality,
[tex]\dfrac{a}{\sin \angle F} = \dfrac{c}{1} \\\\\\\dfrac{a}{\sin \angle F} = c\\\\\\\dfrac{a}{c} = sin \angle F\\\\[/tex]

Or, in other words,

[tex]\sin \angle F = \dfrac{a}{c}[/tex]

Using proportions, the inequality that could be used to determine if a model's height is within the designer's preferred height range is of:

67 inches ≤ Height ≤ 73 inches.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using operations such as multiplication and division, from the unit rates in the context of the problem.

One example of application of proportions is for conversion of units, as there are rates for each unit.

In the context of this problem, the rate used is:

1 feet = 12 inches.

Hence the measure of 5'10" = 5 feet and 10 inches is given by:

5 x 12 + 10 = 60 + 10 = 70 inches.

The heights that are within 3 inches of 70 inches are given by:

Squaring a number means you multiply it with itself.

The square root goes in reverse to have [tex]\sqrt{144} = 12[/tex]

Answer:

Each side is 12 ft long.

Step-by-step explanation:

So, you have a square, which means all of the sides are going to be the same length. So, you need something times itself that equals 144. Or, you need the square root of 144 (Because when something is squared, it is multiplied by itself). And the square root of 144 is 12.
