8P4
= 8 x 7 x 6 x 5 x 4! / 4!
= 8 x 7 x 6 x 5
= 1680
Answer: you will burn 900 calories.
Step-by-step explanation: If the function is linear, each hour burns 300 calories. 300 times 3 is 900. 900 is your answer.
Well
i=√-1 so
i^2=(√-1)^2=-1
remember that
x^(mn)=(x^n)^m
i^40=(i^2)^20
we know that i^2=-1 so
i^40=-1^20
-1^2=1
-1^3=-1
-1^4=1
-1^5=-1
we conclude that even powers of -1 yeild +1 so the answer is +1 (positive 1)
Slope of a line passing through two given points
= (y2-y1)/(x2-x1)
For m=3, and substituting coordinates,
3=(1-y)/(4-1)
solve for y
1-y=3*3=9
y=1-9=-8
Answer: y=-8
Answer:
You'd want to divide.
Step-by-step explanation:
Let's say you got a 9/10 on a test.
You'd do 9 divided by 100 and multiply it by 10 to get 90%
That is how you solve a percentage problem
FORMAT IN LESS DETAILED EXPLANATION:
9/100x10=90%
Nine divided by one-hundred times ten equals ninety percent
