Answer:
Step-by-step explanation:
We're going to use the distance formula to find the distance between two points. The formula is:
d =
Our two points are (x1, y1) and (x2- y2)
Let's make the point (0, 0) be our (x1, y1), and the point (4, 7) be our (x2, y2).
Substitute the points into the formula.
d =
d =
d =
d =
I don't know if the question is asking for the exact value or the decimal value, but the exact value is . You can put that value into a calculator to find the decimal value.

Answer:6.37
Step-by-step explanation:
f(x)= −0.07x²+ 0.42x+ 6.37
1. Find the x-coordinate. x= -(b/2a)
= -(0.42/-0.07) = 6
x=6
2. Find the corresponding y-coordinate.
f(x)= −0.07x²+ 0.42x+ 6.37
substitute x with 6
-0.07(6)²+0.42(6)+6.37
Simplify
-2.52+2.52+6.37=
6.37
Answer:
13.245 rounded to the nearest tenth is 13.2 seconds
Step-by-step explanation:
Ro round a number to the nearest 10, look at the units digit. If the units digit is 5 or more, round up. If the units digit is 4 or less, round down.
Because they do not cross each other and never will cross.
