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
Help me find the area :)
Answer:
400 cm²
Step-by-step explanation:
25÷20 = 1.25
Area = 1.25 × 320
= 400 cm²
Answer:
500
Step-by-step explanation:
Base is 20, height is 16, the larger one is 1.25 times larger, so the height of the larger one is 16*1.25=20. This means that the area of the larger one is 20*25=500.

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.

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

The graph shows two lines, A and B.
Based on the graph,
which statement is correct about the solution to the system of equations for lines A and B?
• (4, 4) is the solution to line A but not to line B.
(4, 4) is the solution to both lines A and B.
(5, 1) is the solution to line B but not to line A.
(0, 2) is the solution to both lines A and B.
Answer:
(4,4) is the solution to both lines A and B
Step-by-step explanation:
As you can see from the graph, both lines passes through (4,4), which means it can be substitute in both equations of those lines

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

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
