4/5 seconds is 0.8 seconds as a fraction.
Step-by-step explanation:
Scale factor is found by making a fraction of two numbers;
In this case, 3.5/2, since the dilated line is larger
Scale factor: 1.75 (simplified)
Given that QYprime is 4.125,
4.125 * (2/3.5)
= 2.357 (rounded)
Answer:
.42 miles more
Step-by-step explanation:
12.98 minus 12.56
Question 1)
Given the points
Finding the slope between (3, 5) and (3, -6)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [-6 - 5] / [3 - 3]
= -11 / 0
= undefined or ∞
Thus, the slope of the line = m = undefined.
Note: The undefined slope means the line is vertical.
Question 2)
Given the points
Finding the slope between (-6, 2) and (8, 2)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [2 - 2] / [8 - (-6)]
= 0 / 14
= 0
Thus, the slope of the line = m = 0.
Note: The zero slope means the line is horizontal.
-3 degrees celsius because -7 + 2 = -5, -5 + (-4) = -9, and -9 divided by 3 = -3.
