(2j+7)(2j−7)
=(2j+7)(2j+−7)
=(2j)(2j)+(2j)(−7)+(7)(2j)+(7)(−7)
=4j2−14j+14j−49
=4j2−49
The rate of change is the same as the slope.
Let's find the slope of function 1 using the Rise Over Run rule.
The rise is 2 and run is 1. So your rate of change is 2/1 or 2 for function 1
Function 2 is a y = mx + b equation, the slope is usually "m" or before the x
y = 1/2x + 7
1/2 is your rate of change for function 2
You will have to divide 353 millimeters by 4:
353 ÷ 4 = 88.25
now we have to multiply 88.25 by 9 (5+4), the total millimeters of only one portion of this drug
88.25 x 9 = 794.25
So he will make 794.25 millimeters of drug (that is if he has the part a too)
(If you should round 88.25 to 88, the answer would be 88 x 9 = 792)
Answer 4: Angle 4,5 and 1
Answer 5: 3,4 and 5
Answer 6: The value of x is 10 because since angle 3 is 90 degrees angle 1 is 9x 9 times 10 equals 90 degrees which is the same as angle 3 which is 90 degrees, so the answer is 10.
