Answer:

2400 cm^2

Step-by-step explanation:

The surface area for a cube is just 6* area in one face (As there are 6 faces), so 6*20^2 = 6*20*20 = 2400 cm^2

Answer:

△ABC is congruent to △DEF

Step-by-step explanation:

△DEF is a reflection of △ABC across the y-axis. (Each x-coordinate is negated.)

Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing,

alina1380 [7]

Answer:

We are have the function f(x).

Part 1: It is given that the function f(x) is transformed to f(x)+2.

This gives us that the function is translated 2 units upwards.

As, the y-intercept of f(x) is f(0). So, the y-intercept of f(x)+2 is f(0)+2, which is also translated 2 units up.

Translation does not change the behavior of the function.

So, if f(x) is increasing (or deceasing), then f(x)+2 will be increasing(or decreasing) respectively.

Moreover, f(x)+2 will be even or odd if f(x) is even or odd respectively.

Part 2: It is given that the function f(x) is transformed to $\frac{-1}{2}f(x)$

This gives us that the function is shrinked vertically by a factor of $\frac{1}{2}$ followed by a reflection across x-axis.

Also, the y-intercept of is $\frac{-1}{2}f(0)$ .

The graph of f(x) after changing to $\frac{-1}{2}f(x)$ will flip over the x-axis.

So, the function $\frac{-1}{2}f(x)$ will increase or decrease when f(x) decrease or increase respectively.

Moreover, $\frac{-1}{2}f(x)$ will be even if f(x) is even or odd respectively.

Find the amount at 6% simple interest of rs 1200 due in month

Ad libitum [116K]

How to calculate simple interest?

Principal: The money which we deposit in or the lower from the bank or the money learned called the principal.

Rate of interest: The interest paid on $ 100 for one year is called the rate per cent per year or rate per cent per annum.

Time: The period of time for which the money is lent or invested.

Interest: Additional money paid by the borrowed to the lender for using the money is called interest.

Simple Interest: If the interest is calculated uniformly on the original principal throughout the lone period, it is called simple interest.

Amount: The total money paid back to the lender is called the amount.
