Answer:
Step-by-step explanation:
Time taken to drive to work = 1 hr
Time taken to drive home = 1 hr
Time taken to drive from home to work and back home again ( IN ONE DAY)
=1 + 1 = 2hrs
So time taken for driving to and from work for 5 days = 2hrs × 5 days = 10 hrs .

Answer: (-5,-3)
Step-by-step explanation:
first you must know left and right is the x-axis while you and down is 4-axis, down and left is subtraction, right and up is addition
so 3 units left would affect x axis therefor subtracting 3 from -2 which is -5
now 5 units down would be the y-axis and subtracting, 2-5= -3
finally your answer will be (-5,-3)
A though without graphing software it would appear to be C
Step-by-step explanation:
The inverse of a function is the function reflected across the line y=x. This results in the coordinate points (x,y) of the function becoming (y,x) for the inverse function. Algebraically to find the inverse, switch the x and y locations and solve for y.
y = 7x^9
x = 7y^9
x/7 = y^9
(9)√(x/7) = y
This is a ninth root of (x/7) also written in exponents as y = (x/7)^(1/9).
This is a function. While it appears not to be a function because the middle portion over the origin appears vertical, it is a function because the middle portion over the origin is changing and graphing software shows it has no input with more than one output. Without graphing software you would rule it is not a function.
Answer:
16 * √3 cm² or approximately 27.71 cm²
Step-by-step explanation:
Given the 8 cm length of the diagonal and the 30° (π/6 radians) angle with one of the sides, we can calculate the width and height of the rectangle using:
8 * cos(π/6) = 8 * ((√3)/2) = 4 * √3
8 * sin(π/6) = 8 * (1/2) = 4
Multiply those two values together to get the area and you get
16 * √3 cm²
