We can just add all these numbers together because they are just addition and subtraction.

We assume the miner starts at 0 (the surface).

0 - 1200 (down) + 900 (up) - 350 (down) = -650 (C)

Write to explain how subtracting 4/5 - 3/5 is similar to subtracting 4 -3
kondor19780726 [428]
Subtracting fractions with a common denominator, you subtract only the numerator, which are 4 and 3, and keep the common denominator the same, underneath the fraction. It is just subtracting 4 and 3 and putting them in a fraction, just like 4-3

Which of the following options results in a graph that shows exponential growth?
poizon [28]

Answer:

f(x)=0.7(5)^x

Step-by-step explanation:

\text{Exponential function: }y=a\cdot b^x

It is two types of function.

  • Exponential Growth: If function increase as value of x increase.

In this case, a>0 and b>1

  • Exponential decay: If function decrease as value of x increase.

In this case, a>0 and 0<b<1

We need to choose exponential growth function.

\text{Exponential Growth function: }f(x)=0.7(5)^x

Here a=0.75>0 and b=5>1

Therefore, This function is exponential growth.
