42825 or 9360
Step-by-step explanation:
So we know that Mt. Everest has a peak that is 29,029 feet above sea level.
To find how much Mauna Kea is above sea level then we would subtract the feet below sea level (19,669ft) from the overall height of the mountain (33,465ft). Like this:
33,465ft - 19669ft = 13,796 feet
Now that we know both mountains height above sea level, we can answer the question.
We will take Everest's height above sea level and subtract Mauna's height above sea level. Like this:
29,029ft - 13,796ft = 15,233
Therefore, Mt. Everest is 15,233 feet taller above sea level than Mauna Kea.
Hope this helps!

Write the cubic polynomial function f(x)in expanded form with zeros −6, −4,and −1,given that f(−2)=−32.
Answer:
[tex]f(x)=4x^3+44x^2+136x+96[/tex]
Step-by-step explanation:
Polynomials
It's possible to build a polynomial function by knowing its zeros and leading coefficient.
Given the zeros of a third-degree polynomial: x=x1, x=x2, and x=x3, the function is:
[tex]f(x)=a(x-x_1)(x-x_2)(x-x_3)[/tex]
Where a is the leading coefficient.
We are given the zeros -6, -4, and -1, thus:
[tex]f(x)=a(x+6)(x+4)(x+1)[/tex]
The value of a can be calculated by substituting the point (-2,-32):
[tex]a(-2+6)(-2+4)(-2+1)=-32[/tex]
Calculating:
[tex]a(4)(2)(-1)=-32[/tex]
[tex]-8a=-32[/tex]
Dividing by -8:
[tex]a = -32/(-8) =4[/tex]
a = 4.
The polynomial is now complete:
[tex]f(x)=4(x+6)(x+4)(x+1)[/tex]
Operating:
[tex]f(x)=4(x^2+10x+24)(x+1)[/tex]
[tex]f(x)=4(x^3+11x^2+34x+24)[/tex]
[tex]\mathbf{f(x)=4x^3+44x^2+136x+96}[/tex]

A beach is 2 3/5 miles long. Pets are allowed on 1/3 of the beach. How many miles of beach are pets allowed?
Answer:
13/15 of 1 mile, or 0.86666 miles
Step-by-step explanation:
If you are working with fractions, you can take the 2 3/5 miles of beach and convert that to 13/5 (10/5 = 2, then add the 3/5 = 10/5+3/5 = 13/5). Once converted, you can find out how much of that number allows pets by dividing that number by 3, or multiplying the result by 1/3.
13/5 * 1/3 = 13/15.
Another way to do this is to convert the original miles (2 3/5) to a decimal, which gives you 2.6 miles. Then take the 2.6 miles and again, either divide by 3 or multiply by 1/3 (which is basically the same thing). 2.6 ÷ 3 = 0.86666

"X is the number of red marbles that Tonya has in her hand after she selects four marbles from a bag containing four red marbles and two green ones and then notes how many there are of each color."
Answer:
Explained below.
Step-by-step explanation:
There are four red marbles (R) and two green marbles (G) in the bag.
The random variable X is defined as the number of red marbles that Tonya has in her hand after she selects four marbles from the bag.
The probability of selecting a red marble is:
[tex]P(X)=\frac{4}{6}=0.667[/tex]
The sample space of X can be defined as follows:
Outcomes: {(RGGG), (RRGG), (RRRG), (RRRR), (RRGR), (RGRR), (GRRR), (RGRG), (GRRG), (RGGR), (GRGR), (GRGG), (GGRG), (GGGR), (GGGG)}
So, the sample space of X is:
S = {0, 1, 2, 3 and 4}
HHHHHHHHHHHHHHHHEEEEEEEEEEEEEEEEEEELLLLLLLLLLLLLLLPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPpppppppppJane sells pillows. For a sale, she marks them down 5%. If the original price of a pillow is $15.00, what is the sale price?
Answer:
$ 14.25 this is probably the answer
The required two expressions are
(1-0.05)P
0.95 P
Step-by-step explanation:
First method : Here, the original price of pillow = P,
She marks them down 5%
Thus, the selling price = P - 5% of P = P - 0.05 P = (1-0.05)P
Second method :
Since, some number is 100% of itself,
⇒ 100 % = P
⇒ 1 % = P/100 = 0.01 P
Also, by decreasing 5 % from 100 %
The remaining percentage = 100 - 5 = 95%
⇒ 95 % = 95 × 0.01 = 0.95 P

Jason purchased a pack of game cards that was on sale for 13% off. The sales tax in his country is 8%. Let y represent the original price of the cards. Write an expression that can be used to determine the final cost of the cards.
Answer: The correct option is option (B) 1.08(0.87y).
Step-by-step explanation:
The answer is B
100% - 13% = 87% or .87
Tax is 8% or .08
Total cost would be 1 + .08 x .87
or 1.08(0.87y)

Successive discounts of 20% and 10% are taken on an item priced at $16. Describe how to find the sale price of the item
and give the sale price.
Answer:
$11.52
Step-by-step explanation:
16 * .2 = 3.2
16 - 3.2 = 12.8
12.8 * .1 = 1.28
12.8 - 1.28 = $11.52
Take the given amount and take 20% off using the first 2 solutions, then take the "successive" discount of 10% using the second 2 solutions to get the final sale price
Stephanie also is 2/5 m Ike’s in 1/4 hour. What is her speed in mikes per hour?
Answer:
1.6 m/hr
Step-by-step explanation:
(Time) 1/4 of an hour = .25 or 15 mins
Distance = 2/5 mile or .40
Speed = distance / time
Speed = .40 / .25
Speed = 1.6 m/hr
Answer:
1 3/5 or 1.6 mph
Step-by-step explanation:
2/5 of a mile = 0.4 miles
0.4 x 4 = 1.6 or 1 3/5 (you get the 4 from multiplying 1/4 of an hour by 4 to get one hour)

Find the equation of the circle that has a diameter with endpoints (-4,8) and (4,-4)
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
First we need to find the distance between two points which is the diameter of the circle .
_________________________________
Suppose :
a = ( - 4 , 8 )
b = ( 4 , - 4 )
We have following equation to find the distance between two points.
[tex]distance = diameter = d[/tex]
[tex]d = \sqrt{ ( \: {y(b) - y(a)} \: )^{2} + ( \: {x(b) - x(a)} \: )^{2} } \\ [/tex]
Now just need to put the coordinates :
[tex]d = \sqrt{ ({ - 4 - 8})^{2} + ( \: {4 - ( - 4)} \: )^{2} } \\ [/tex]
[tex]d = \sqrt{ ({ - 12})^{2} + ({4 + 4})^{2} } [/tex]
[tex]d = \sqrt{ ({ - 12})^{2} + ({8})^{2} } [/tex]
[tex]d = \sqrt{144 + 64} [/tex]
[tex]d = \sqrt{208} [/tex]
[tex]d = \sqrt{4 \times 52} [/tex]
[tex]d = \sqrt{4 \times 4 \times 13} [/tex]
[tex]d = \sqrt{ {4}^{2} \times 13 } [/tex]
[tex]d = 4 \sqrt{13} [/tex]
This is the diameter of the circle.
We know that :
[tex]diameter = 2 \times radius[/tex]
So :
[tex]4 \sqrt{13} = 2 \times radius[/tex]
Divide sides by 2
[tex] \frac{4 \sqrt{13} }{2} = \frac{2 \times radius}{2} \\ [/tex]
[tex]2 \sqrt{13} = radius[/tex]
Remember it.
_________________________________
To find the equation of the circle except the radius , we need the coordinates of the centre.
The midpoint of the diameter is the centre of the circle .
So we have to find the midpoint of the diameter .
Look :
[tex]midpoint = center = o[/tex]
[tex]o = ( \: \frac{x(a) + x(b)}{2} \: , \: \frac{y(a) + y(b)}{2} \: ) \\ [/tex]
[tex]o = ( \: \frac{ - 4 + 4}{2} \: , \: \frac{8 - 4}{2} ) \\ [/tex]
[tex]o = ( \: \frac{0}{2} \: , \: \frac{4}{2} \: ) \\ [/tex]
[tex]o = ( \: 0 \: , \: 2 \: )[/tex]
This the coordinates of the centre.
_________________________________
Equation of the circle has a form like this :
[tex]( {x - m})^{2} + ({y - n})^{2} = {r}^{2} [/tex]
In which :
[tex]m = x - coordinate \: \: of \: \: the \: \: center \\ [/tex]
[tex]n = y - coordinate \: \: of \: \: the \: \: center \\ [/tex]
[tex]r = radius[/tex]
_________________________________
[tex]o = ( \: 0 \: , \: 2 \: )[/tex]
[tex]radius = 2 \sqrt{13} [/tex]
Thus :
[tex] ({x - 0})^{2} + ({y - 2})^{2} = ({2 \sqrt{13} })^{2} \\ [/tex]
[tex] {x}^{2} + ({y - 2})^{2} = 4 \times 13[/tex]
[tex] {x}^{2} + ({y - 2})^{2} = 52 [/tex]
This is the equation of the circle .
And we're done....

write slope form of lines satisfying the given coditions then use the point slope form of the eqation to write the slope intercept form of the equation slope = 4, passsing through (-3,9)
Here is how to find the equation of the line using point-slope form
Formula for the equation of a line in point-slope form: y - y₁ = m(x - x₁)
Now that we have the formula, we plug in what we are given.
y - 9 = 4(x + 3)
We can covert this into slope-intercept form by solving for y.
[tex]y - 9 = 4(x + 3)\\\\y - 9 = 4x + 12\\\\y = 4x + 21[/tex]
Our equation for this line is: y = 4x + 21.
We can prove this by graphing the line, like so:

Work out the percentage change to 2 decimal places when a price of £12 is increased to £15.99. Work out the percentage change to 2 decimal places when a price of £12 is increased to £15.99.
Answer:
[tex]\%Increase = 33.25\%[/tex]
Step-by-step explanation:
Given
Initial = 12
Final = 15.99
Required
Determine the percentage increment
This is calculated as thus:
[tex]\%Increase = \frac{Final - Initial}{Initial} * 100\%[/tex]
Substitute values for Initial and Final
[tex]\%Increase = \frac{15.99 - 12}{12} * 100\%[/tex]
[tex]\%Increase = \frac{3.99}{12} * 100\%[/tex]
[tex]\%Increase = \frac{3.99* 100\%}{12}[/tex]
[tex]\%Increase = \frac{399\%}{12}[/tex]
[tex]\%Increase = 33.25\%[/tex]
Hence, the percentage increment is 33.25%
