3x(sqrt 4x+5)/4x+5
You have to multiply the numerator and denominator by sqrt 4x+5 in order to rationalize
Answer:
a)
The equation of variation is;
N = 80000*S
b)
14400000
Step-by-step explanation:
We are informed that the number of instructions N performed per second by a computer varies directly as the speed S of the computer's internal processor. This means that N and S are directly proportional;
N∝S
Introducing a constant of proportionality, k;
N=k*S
We shall find the value of k by using the information given;
N = 1600000
S = 20
k = 1600000/20
= 80000
a)
The equation of variation is thus;
N = 80000*S
b)
We are required to find N when S = 180
Using the equation of variation obtained above;
N = 80000 (180)
= 14400000
y=-2x
We know this because the slope is -2 (slope is found using rise/run, in this case the rise is 2 and the run is -1, so 2/-1=-2), and the y-intercept is at 0 (the y-intercept is the point at which a line crosses the y-axis).

Where are the expressions?
You can divide 59/20 which equals 2.95. Then multiply that by a hundred which gives you 295%
