Answer:
Each golf ball costs about $0.51
1. Divide $9.17 by 18
The answer you will get is 0.509
2. Round 0.509
The answer you will get is 0.51
So therefor, the answer to this question how much did each golf ball cost is $0.51 per golf ball.
Answer: Option A.
Step-by-step explanation:
For a function f(x) = y, the domain is the set of the possible values of x.
In the image we can see that the graph has two arrows, one pointing to the left and another pointing to the right, this means that the function extends infinitely to both sides.
Then there is no value of x that generates a given problem, then the domain is the set of all real numbers.
The set written in interval notation is:
-∞ < x < ∞
Then the correct option is A.
Answer:
Step-by-step explanation:
A vertical stretch of a function means the output values have changed by a factor of 3 or multiplication by 3. Recall, an exponential function has the basic form
.
If our equation is , then a=1. To stretch it vertically by a factor of 3, we multiply a by 3. So 1(3)=3. The value of a now becomes 3.
Hello!
To start, since you already know that you can drive 3000 miles in 75 hours, but you need to know how long it will take to drive 4000 miles, you can solve using a proportion, where x is the amount of hours:
3000/75=4000/x
When you have set this up, cross multiply:
3000*x=75*4000
After you have cross multiplied, you will result in this:
3000x=300000
Then, solve for x and you will get x=100, meaning it will take Cheyenne 100 hours to drive 4000 miles.
