My name is Ann [436]3 years ago
7 0

Step-by-step explanation:

We can turn this into an equation.

Let’s denote the amount of money James makes as X.

Then Lin makes X + 3100.

Together they make 81960.

So combine their earning expressions.

X + X + 3100 = 81960

Solve for X

X = 39430

So James makes $39430 since his earnings are demoted by x.

Lin then makes 3100 + 39430, which is $42530.

For the function f(x)=5x2−5x, evaluate and simplify.
Marianna [84]

9514 1404 393

Answer:

  10x -5 +5h

Step-by-step explanation:

Use the function definition with the given arguments.

  \dfrac{f(x+h)-f(x)}{h}=\dfrac{(5(x+h)^2-5(x+h))-(5x^2-5x)}{h}\\\\=\dfrac{(5(x^2+2hx+h^2)-5(x+h))-(5x^2-5x)}{h}\\\\=\dfrac{5x^2+10hx+5h^2-5x-5h-5x^2+5x}{h}=\dfrac{10hx-5h+5h^2}{h}\\\\=\boxed{10x-5+5h}

Function h models an object's height in feet after x seconds have passed. Which equation shows that the object's height increase
ASHA 777 [7]

Answer:

C

Step-by-step explanation:

We know that function <em>h</em> represents an object's height in feet after <em>x</em> seconds.

In that case, option A) h(15) = 100 means that after 15 seconds, the object's height is 100 feet.

Option B) h(100) = 15 means that after 100 seconds, the object's height is 15 meters.

Therefore, neither A nor B are correct.

Option C) h(15) - h(0) = 100 means that between the zeroth and 15th second, their difference is 100 feet.

In other words, the object's height increased by 100 feet over the first 15-second period.

Option C is correct.

For Option D), it gives us the average rate of change. (h(15) - h(0)) / (15) = 100 means that for the first fifteen seconds, the height of the object increased at an average rate of 100 feet per second.
