Answer:
90 miles
Step-by-step explanation:
Let d represent the distance to Grandma's house.
The speed going was ...
speed = distance/time
speed = d/2
The speed coming home was ...
speed = d/2.25
The difference of these speeds is 5 miles per hour:
d/2 -d/2.25 = 5
2.25d -2d = 5(4.50) . . . . . multiply by 4.50
0.25d = 22.5 . . . . . . . . . . .simplify
d = 90 . . . . . . . . . . . . . . . . multiply by 4
Grandma's house is 90 miles away.
Answer:
A
Step-by-step explanation:
Since x is along the entire parallelogram we will use cosine to figure out it's length.
First we do cos(40) and get cos(40)=.7660
This .7660 is equal to or
So we do .7660*4 and get 3.064 in for x
A is the only option with x=3.06 so it is the correct answer
the correct options are:
- The function has a domain of all real numbers.
- The function has a range of {y|–Infinity < y < Infinity} (this is the same as saying that the range is the set of all real numbers.
<h3>
Which statements are true about the function?</h3>
Here we have the function:
First, this is a cubic root, so its domain is the set of all real numbers (same for the range). And we know that the cubic root is an increasing function, so if we put a negative sign before it, we will have a decreasing function.
Then the correct options are:
- The function has a domain of all real numbers.
- The function has a range of {y|–Infinity < y < Infinity} (this is the same as saying that the range is the set of all real numbers.
The fourth option is incomplete, so we can't conclude if it is true or not, it would be true if it said:
"The function is a reflection over the x-axis of y = ∛x"

It is 17/50 because 17 times 2 is 34 and 50 times 2 is 100. That 17/50 is the lowest it can go so that is your answer.
17/50 is ur answer
If u r trying 2 find the absolute value of a positive number, the absolute value of it will not be a negative, it will always be a positive.
