Answer:

Below in bold.

Step-by-step explanation:

First find the height by use Pythagoras theorem on the right triangle:

h = sqrt (5^2 - 4^2)

= sqrt 9

= 3.

Volume of the prism = area of the triangle * length

= 1/2 * 3 * 4 * 10

= 1/2 * 12 * 10

= 60 cm^3.

Total area = area of 2 triangles + area 0f 3 rectangles

= 2 * 1/2 * 3 * 4 + 3 * 10 +  4 * 10 + 5 * 10

= 12 + 30 + 40 + 50

= 132 cm^2.

Which equation represents the total interest, T, earned when the principal amount is $100, the annual simple
netineya [11]

Answer:

The answer is option (C), T = 100 • 0.1 • 10

Step-by-step explanation:

Total interest (T) earned after a 10 years can be expressed as;

Total interest (T)=Principal amount×interest rate×Number of years

where;

Total interest=T

Principal amount=$100

Interest rate=10%=10/100=0.1

Replacing;

T=100×0.1×10

The equation for calculating the total interest amount after 10 years can be written as;

T = 100 • 0.1 • 10

The concept and full method
marin [14]

Answer:

Step-by-step explanation:

This kinda looks like the limiting definition of a derivative.  

Anyway, what we are doing with the f(2 + h) is evaluating f(x) with 2+h in place for x.  That looks like this:

f(2 + h) = 2(2 + h) - 3 which simplifies to

f(2 + h) = 4 + 2h - 3 which simplifies to

2h + 1

From that we are subtracting f(2).  What we are doing with that is evaluating f(x) with 2 in place for x.  That looks like this:

f(2) = 2(2) - 3 which simplifies to

f(2) = 4 - 3 which simplifies to

f(2) = 1.  Now put those together over h to get:

\frac{f(2+h)-f(2)}{h}=\frac{2h+1-1}{h}=\frac{2h}{h}=2
