Answer:
Daniel is rollerblading at 15 miles per hour
Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15
Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15
Step-by-step explanation:
One meaning of a 'linear' equation is that if you draw the graph
of the equation, the graph will be a straight line.
That's an easy way to test the equation . . . find 3 points on the
graph, and see whether they're all in a straight line.
This equation is y = 4 / x .
To find a point on the graph, just pick any number for 'x',
and figure out the value of 'y' that goes with it.
Do that 3 times, and you've got 3 points on the graph.
Here ... I'll do 3 quick points:
Point-A: x = 1 y = 4 / 1 = 4
Point-B: x = 2 y = 4 / 2 = 2
Point-C: x = 4 y = 4 / 4 = 1
Look at this:
Slope of the line from point-A to point-B
= (change in 'y') / (change in 'x') = -2 .
Slope of the line from point-B to point-C
= (change in 'y') / (change in 'x') = -1/2 .
The two pieces of line from A-B and from B-C don't even have
the same slope, so they're not pieces of the same straight line !
So my points A, B, and C are NOT in a straight line.
So the equation is NOT linear.
Try it again with three points of your own.
1) Write the number in exponential form with a base of 10:
3√1000 = 3√10^3
2) Reduce the index of radical and exponent with 3:
3√10^3=10
Answer:
there is 16.08 foot high does the ladder reach on the building
Step-by-step explanation:
The computation of the high does the ladder reach on the building is shown below:
Given that
length of the ladder = 17 ft
angle -between the ground and the ladder = 75 degrees
Based on the above information
Here we used the trig-ratio to calculate the same
0.946 × 17 = h
The height is 16.08 foot
Hence, there is 16.08 foot high does the ladder reach on the building
Slope of 4 means you add 4 to the y and 1 to the x so the answer is (-1,9)
