12 x 12 x 3.14 = 452.16
3.14 x 12 x 15 = 565.2
565.2 + 452.16 = 1,017.36
A sample of nitrogen gas has a pressure of 6.58 kPa at 539K. If the volume does not
change, what will the pressure be at -62C.
Answer:
2.575844
Step-by-step explanation:
This is a simple change of temp problem, from 539K to -62C but to start you have to change the C to K, which is simply adding 273 to the -62 so 211K.
Now you take P1/T1 = P2/T2 so,
6.58 = x
539 = 211
now cross multiply and divide, 211 x 6.58 then divide by 539.
this will give you your answer

Which function has the greater rate of change? Function 1: y = -1/2x +5
or Function 2: y = -3/4x - 4
I’ll give brainliest
The rate of change is the slope. The slope is the number in front of the x
Function 1 rate of change is -1/2
Function 2 rate of change is -3/4
The greater rate of change would be the steepest slope.
Function 2 has the greater rate of change

The equation y=36.5x represents the number of miles, y, that Katherine can drive her car for every, x, gallons of gas. Find the rate of change.
Answer:
36.5miles/gallon
Step-by-step explanation:
Given the equation y=36.5x which represents the number of miles, y, that Katherine can drive her car for every, x, gallons of gas. The rate of change of the function is expressed as dy/dx
On differentiating the function;
dy/dx = 36.5
Hence the rate of change of the function is 36.5miles/gallon
Richard and Jordan went to see a movie. Richard spent in dollars at the movie theater, and Jordan spent $12 at
the movie theater. Together they spent a total of $26.
Help me please
Answer:
$m + $12 = $26
Or
m + 12 = 26
Step-by-step explanation:
Amount spent by Richard = $m
Amount spent by Jordan = $12
Total amount spent together = $26
An equation that describes this situation would be:
$m + $12 = $26
Or
m + 12 = 26

The population of a city increases by 3.1% per year. If this year's population is 119,000, what will next year's population be, to the nearest individual?
- I just honestly don't know where to start. I haven't done percents in a while, so I need to jog my memories. Any advice on where to start?
Answer:
The next year population is 122,689
Step-by-step explanation:
The computation of the next year population is as follows:
= This year population × increase percentage
= 119,000 × (1 + 0.031)
= 119,000 × 1.031
= 122,689
Hence, the next year population is 122,689
The above formula is applied so that the correct value of the population could come
and the same is relevant

Answer:
1,420 grams per 100 baseballs
Step-by-step explanation:
Set up an equation:
Variable x = grams per 100 baseballs
1/14.2 = 100/x
Cross multiply
1 × x = 14.2 × 100
1x = 1420
x = 1420

which is the solution set for the quadratic equation x^2-9=0
===================================================
Explanation:
We could add 9 to both sides, and then apply the square root to both sides. Don't forget about the plus minus
x^2 - 9 = 0
x^2 = 9
x = sqrt(9) or x = -sqrt(9)
x = 3 or x = -3
To check these answers, you replace x with those values we found. I'll show you how to check x = 3
x^2 - 9 = 0
(3)^2 - 9 = 0
9 - 9 = 0
0 = 0
So that confirms x = 3. The confirmation for x = -3 is nearly the same. Keep in mind that (-3)^2 = (-3)(-3) = 9. You'll be squaring the negative as well.
------------------
Another method you could do is to use the difference of squares rule
x^2 - 9 = 0
x^2 - 3^2 = 0
(x - 3)(x + 3) = 0
Now apply the zero product property. This effectively means you set each factor equal to zero and solve for x
x-3 = 0 or x+3 = 0
x = 3 or x = -3
We end up with the same solution set.
Yet another method you could use is the quadratic formula, but that may be overkill. It's still good practice to do.
Graphing is a visual way to find the answers. You'll graph y = x^2 - 9 and look to see where the curve crosses or touches the horizontal x axis.

lines m and p are cut by the transversal n. determine the value of x. write the measures of the six angles. show all work
x = 36
Step-by-step explanation:
The angles 4x and x are supplementary, meaning they add up to 180; therefore we have
[tex]4x + x = 180[/tex]
[tex]5x = 180[/tex]
dividing both sides by 5 gives
[tex]x = 36[/tex]
the measure of angle x is 36 and that of 4x is 4 * 36 = 144
The angle opposite to 4x also measures 144 and the one opposite to x is 36.
Answer:
x° + 4x° = 180°
5x° = 180°
x° = 180°/5
x° = 36°

The measures of the three angles of a
triangle are given by 2x + 6, x, and 3x.
What is the measure of the largest angle?
Answer:
[tex]\boxed {\boxed {\sf 87 \ degrees}}[/tex]
Step-by-step explanation:
The angles in a triangle must add to 180 degrees.
We are given three angles: 2x+6, x, and 3x. Their sum must be 180, so we can create an equation.
[tex]2x+6+x+3x=180[/tex]
Combine like terms (all terms with an x) on the left side.
[tex](2x+x+3x)+6=180[/tex]
[tex]6x+6=180[/tex]
Now solve for x by isolating the variable.
6 is being added and the inverse of addition is subtraction. Subtract 6 from both sides.
[tex]6x+6-6=180-6\\6x=174\\[/tex]
x is being multiplied by 6. The inverse of multiplication is division. Divide both sides by 6.
[tex]6x/6=174/6 \\x=29[/tex]
Substitute 29 for x in the angle measures.
2x+6= 2(29)+6=58+6=64x=29 3x= 3(29)=87The largest angle is 87 degrees.
Please help me solve this and also please show me the work :)
Given:
The figure of a right triangle.
To find:
All the six trigonometric ratios for the angle θ.
Solution:
Using the Pythagoras theorem, we get
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
[tex]Hypotenuse^2=(9)^2+(12)^2[/tex]
[tex]Hypotenuse^2=81+144[/tex]
[tex]Hypotenuse^2=225[/tex]
Taking square root on both sides, we get
[tex]Hypotenuse=15[/tex]
Now, the six trigonometric ratios for the angle θ are:
[tex]\sin\theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]
[tex]\sin\theta=\dfrac{12}{15}[/tex]
[tex]\sin\theta=\dfrac{4}{5}[/tex]
[tex]\cos\theta=\dfrac{Base}{Hypotenuse}[/tex]
[tex]\cos\theta=\dfrac{9}{15}[/tex]
[tex]\cos\theta=\dfrac{3}{5}[/tex]
[tex]\tan\theta=\dfrac{Perpendicular}{base}[/tex]
[tex]\tan\theta=\dfrac{12}{9}[/tex]
[tex]\tan\theta=\dfrac{4}{3}[/tex]
[tex]\csc\theta=\dfrac{1}{\sin \theta}[/tex]
[tex]\csc\theta=\dfrac{1}{\dfrac{4}{5}}[/tex]
[tex]\csc\theta=\dfrac{5}{4}[/tex]
[tex]\sec\theta=\dfrac{1}{\cos \theta}[/tex]
[tex]\sec\theta=\dfrac{1}{\dfrac{3}{5}}[/tex]
[tex]\sec\theta=\dfrac{5}{3}[/tex]
[tex]\cot\theta=\dfrac{1}{\tan \theta}[/tex]
[tex]\cot\theta=\dfrac{1}{\dfrac{4}{3}}[/tex]
[tex]\cot\theta=\dfrac{3}{4}[/tex]
Therefore, the six trigonometric ratios are [tex]\sin\theta=\dfrac{4}{5},\cos\theta=\dfrac{3}{5},\tan\theta=\dfrac{4}{3},\csc\theta=\dfrac{5}{4},\sec\theta=\dfrac{5}{3},\cot\theta=\dfrac{3}{4}[/tex].

Use the arithmetic series formula to calculate the sum of the first 15 terms of the sequence: a n =5n+3
Answer:
S₁₅ = 645
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Using the nth term formula [tex]a_{n}[/tex] = 5n + 3 , then
a₁ = 5(1) + 3 = 5 + 3 = 8
a₂ = 5(2) + 3 = 10 + 3 = 13 , then
d = a₂ - a₁ = 13 - 8 = 5
Thus
S₁₅ = [tex]\frac{15}{2}[/tex] [ (2 × 8) + (14 × 5) ]
= 7.5( 16 + 70)
= 7.5 × 86
= 645
