You start at the y axis and go down 7 so the coordinate is (0, 7) then you move to the right five spaces from (0, 7) and go up 4 from the spot you moved right 7. This should have a positive slope
Answer:
a) 6
b) 6i
c) 6i
d) -6
Step-by-step explanation:
We are going to write down the numbers as a product of prime numbers and then proceed to solve:
Note: Remember that i = √-1 and that i²= -1
a) √9(√4)
√3² × √2² = 3 × 2 = 6
Thus, the answer is 6
b) √9 ×√-4
√3² x i√2² = 3 x 2i = 6i
Thus, the answer is 6i
c) √-9.√4
i√3² × √2² = 3i x 2 = 6i
Thus the answer is 6i
d) √-9.√-4
i√3² × i√2²
3i x 2i = -6
Thus the answer is -6
Answer:
-94.5
Step-by-step explanation:
7.5 less 102 is equivalent to the negative of 102 less 7.5: -(102 - 7.5) = -94.5.
It is not strictly necessary to reverse the order of the numbers as shown above, but 102 - 7.5 is more famliar (and thus easier to deal with) than
7.5 - 102.
The measure of the supplementary angle is 148 degrees.
Hope this helps!
Answer:
Time taken T = 2.5 miles/ 0.067 miles per minute
Step-by-step explanation:
In this question. We are asked to give the expression that shows how long in minutes that should be walked on the treadmill.
Now, let’s look at what we have in the question. We have a distance of 2.5 miles and a speed of 4 mph, read as 4 miles per hour.
The question is a term of how long. This means what we are trying to calculate refers to the time taken to walk a total of 2.5 miles on the treadmill at a speed of 4mph.
Mathematically, we know that the time taken would be equal to the distance walked on the treadmill mill divided by the speed used to walk this distance over the treadmill.
This can be written in the equation form as T = D/S
Now if we look at our speed, it is written in hours, but the question stipulated minutes. So what do we do? We simply make a conversion from 4mph to 4mpm. To do this , we simply divide 4mph by 60 to give 0.067mpm.
We now move on to write the time taken. This would be:
T = 2.5 miles/0.067 miles per minute
