Find the slope please​
scoray [572]

The slope of the line is 2.

The slope is going up from left to right, so it'll be positive to start with. From there you have to do rise over run. That is pretty much how many units up and in towards the slope do you have to go until you find 2 points that are in the center of the line. In this case, the rise over run is 2/1 which equals 2.

May I have brainliest please? :)

The useful life of a certain piece of equipment is determined by the following formula: u=(8d)/h^2, where u is the useful life o
Anni [7]

Answer:

The correct answer is E.

Step-by-step explanation:

First I look for the relationships between the coefficients. The first term corresponds to the base value.

\frac{8*d}{h^{2}}  = \frac{8}{1} * \frac{d}{h^{2} }

The second term corresponds to the value obtained when the density of the underlying material is doubled and the daily usage of the equipment is halved.

\frac{2*8*d}{(0,5*h)^{2}}  = \frac{16*d}{0,25 * h^{2}}  = \frac{16}{0,25} * \frac{d}{h^{2} }

With the I get the ratio of coefficients of \frac{d}{h^{2}} :

\frac{8}{1} = 8

\frac{16}{0,25} = 64

Now I calculate  the percentage increase in the useful life of the equipment as:

% = \frac{64}{8} * %100 = %800

If Kevin is 6 years older than Daniel, but also 4 times as old a him, just divide 6 by 4. Your answer is going to be that Daniel is 1 and a half years old
