V = (4/3) pi * r^3

Givens

r = 4.8 years

pi = 3.14

Solution

V = (4/3) * pi * 4.8^3

V = (4/3) * pi * 110.592

V = 1.333*3.14 * 110.592

Answer:

It's 0.61

Step-by-step explanation:

I graphed the equation and got 0.61 on the x axis when the y value was 1.24

The missing x-coordinate is 9.5. The correct answer is option D.

A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.

The given function \(y = 2 -\sqrt{x+1}\) and the point are ( x, -1.24 ). Put y = -1.24 in the given equation to get the value of x.

\(y = 2 -\sqrt{x+1}\)

\(-1.24 = 2 - \sqrt{x+1}\\-1.24 - 2 = \sqrt{x+1}\\-3.24 = \sqrt{x+1}\)

Squaring on both sides.

\((-3.24)^2 = (\sqrt{x+1})^2\)

10.5 = x + 1

x = 9.5

Hence, the correct option is D.

Answer:

Step-by-step explanation:

(x₁ , y₁) = (5 , 1)    & (x₂ , y₂) = (-8 , 3)

\(Distance = \sqrt{(x_2-x_1)^{2} + (y_2-y_1)^{2}}\\\\ =\sqrt{(-8-5)^{2}+(3-1)^{2}}\\\\=\sqrt{-13)^{2}+2^{2}}\\\\=\sqrt{169+4}\\\\=\sqrt{173}units\)

First, we have to calculate the length of each side using the distance formula.

Given two points (x1, y1) and (x2, y2) the distance between them is computed as follows:

Segment IJ: I(-9, -8) and J(-5,-6)

Segment IK: I(-9, -8) and K(-7,-3)

Segment JK: J(-5, -6) and K(-7,-3)

Using Heron's formula,

The probability of the sum of the numbers comes up on the facing dice add up to 3 while rolling two fair six sided dice is equal to ( 1/ 18).

As given in the question,

Number of six sided fair dice rolled = 2

Total number of outcomes of each dice = 6

Total number of outcomes of rolling two six sided fair dice = 36

Outcomes are:

( 1,1), (1,2)...(1,6),( 2,1), (2,2)...(2,6), ( 3,1), (3,2)...(3,6), ( 4,1), (4,2)...(4,6), ( 5,1), (5,2)...(5,6), ( 6,1), (6,2)...(6,6)

Sum of facing up dice add upto 3 are

( 1,2) , (2,1) only

Number of favorable outcomes = 2

Required probability = 2/36

                                = 1/18

Therefore, the required probability of the sum of facing up dice add upto 3 is equal to (1/18).

The given question is incomplete, I answer the question in general according to my knowledge:

Roll two fair 6-sided dice. what is the probability that the sum of the numbers on the dice facing up add up to 3?

The given expression is proved above to its equivalent value.

Given is an exponential expression.

\($e^{(2\pm3\pi i)} = -e^{2}\)

We can write the given expression in two possible ways -

\($e^{2} e^{3\pi i}\)     and        \($\frac{e^{2} }{e^{3\pi i} }\)

Now, we know using the De - Moivre's theorem, we can write -

\($e^{i\theta} =\) cos(θ) + i sin(θ)

Now -

\($e^{3\pi i} =\) cos(3π) + i sin(3π) = - 1

So, we can write -

\($e^{2} e^{3\pi i}\)  = - e²

and

\($\frac{e^{2} }{e^{3\pi i} }=\frac{e^{2} }{-1}\)  

\($\frac{e^{2} }{e^{3\pi i} }=-e^{2}\)  

Therefore, the given expression is proved above to its equivalent value.

Based on these considerations, it is necessary to assess the specific layout plan and the surrounding environment to determine whether the copier is suitably placed in room (3) at Hills Secondary.

To determine whether the copier is suitably placed in room (3) at Hills Secondary, we need to consider factors such as accessibility, noise, and convenience.

Firstly, we need to evaluate the accessibility of the copier in room (3). Is it easily accessible for all students and staff who need to use it? If the copier is located in a central position within the school or close to high-traffic areas, it would be considered suitable.

However, if it is tucked away in a corner or not easily visible, it may cause inconvenience and hinder access for users.

Secondly, we should consider noise levels. Copiers can be noisy machines, and if room (3) is located near classrooms or areas where students require a quiet environment, it may not be an ideal placement. Noise disturbances could disrupt learning activities and cause distractions.

Lastly, convenience plays an important role. Room (3) should be spacious enough to accommodate the copier and allow users to operate it comfortably. If the room is cramped or lacks proper ventilation, it may cause inconvenience for users and impact the overall workflow.

x + x - 45 = 90

2x - 45 = 90

2x = 135

x = 67.5, so x - 45 = 22.5

The other two angles measure 22.5° and 67.5°.

The values of x and y after solving this system of equations will be 32/35 and -88/105 respectively.

System of equations are a set of two or more equations that contain variables. The values of the variables can be calculated using either method of elimination or substitution. The values of the variables must then satisfy all the equations.

For a set of two equations, in elimination we make the coefficient of any one variable equal to the coefficient of the same variable in the other equation. This can be done by multiplying or dividing the whole equation accordingly. Then we subtract the equations from each other and solve for one variable.

6x - 3y = 8 (multiplying this equation by -2 to make the coefficient of y equal to that of in the equation 23x + 6y = 16)

Now are equations are

-12x + 6y = -16 and 23x + 6y = 16

subtracting eq 1 from eq 2 gives,

35x = 32 (Note that y has now been eliminated)

x = 32/35

Substituting this value of x in any one of the equations will then give the value of y to be -88/105

15 blue

15 red

15 green

To figure out the probability of red and blue together, add red and blue.

Answer:

x = 19.5

Step-by-step explanation:

Given that Polygon HIJK is similar to Polygon PQRS, their corresponding lengths are congruent, also, the the ratio of the sides of HIJK to the corresponding sides of PQRS would be the same.

Thus:

\( \frac{HI}{PQ} = \frac{IJ}{QR} \)

HI = 15

PQ = 5

IJ = x

QR = 6.5

Plug in the values

\( \frac{15}{5} = \frac{x}{6.5} \)

\( 3 = \frac{x}{6.5} \)

Multiply both sides by 6.5

\( 3*6.5 = x \)

\( 19.5 = x \)

Answer:

x- intercept = - 8 , y- intercept = 4

Step-by-step explanation:

to find the x- intercept let y = 0 in the equation and solve for x

x - 2(0) = - 8

x - 0 = - 8

x = - 8 ← y- intercept

to find the y- intercept let x = 0 in the equation and solve for y

0 - 2y = - 8

- 2y = - 8 ( divide both sides by - 2 )

y = 4 ← y- intercept

10% of the time, the population mean will go below $1,500 or exceed $2,100.

Given that,

Assume that we have data on the annual spending on apparel of a sample of families. The probability that the population mean will fall below $1,500 or rise over $2,100 is ________% if we are 90% positive that the genuine population mean will be between $1,500 and $2,100.

We have to fill the blank.

We know that,

90% of the time, the real population mean will fall in the range of $1,500 and $2,100.

The genuine population mean will therefore most likely fall between $1,500 and $2,100, with a 90% probability.

So, the probability that it will fall outside of this range (i.e., be either less than $1,500 or beyond $2,100) is 100-90, or 10%.

Therefore, 10% of the time, the population mean will go below $1,500 or exceed $2,100.

The quadratic equation will be;

⇒ y = 14/25 x² - 4

The linear coefficient = 0

The constant term = - 4

What is Quadratic equation?

An algebraic equation with the second degree of the variable is called an Quadratic equation.

Given that;

A quadratic function has its vertex at the point ( 0, -4 ).

The function passes through the point ( − 5 , 10 ).

Now,

Since, A quadratic function has its vertex at the point ( 0, -4 ).

So, The equation we get;

⇒ y = a ( x - 0)² - 4

And, The function passes through the point ( − 5 , 10 ).

So, we substitute (x, y) = (-5, 10) , we get;

⇒ y = a ( x - 0)² - 4

⇒ 10 = a ( - 5 - 0)² - 4

⇒ 10 + 4 = 25a

⇒ 14 = 25a

⇒ a = 14 / 25

Thus, The quadratic equation will be;

⇒ y = a ( x - 0)² - 4

⇒ y = 14/25 x² - 4

⇒ y = 14/25 x² - 4

Therefore, The quadratic equation will be;

⇒ y = 14/25 x² - 4
