dusya [7]3 years ago
4 0

Answer:

The incorrect statement is decreasing from (-∞, -1)

Step-by-step explanation:

Intercepts are where it touches the axis

The x intercepts are -2 and 1

Increasing is where it goes up

We are increasing from (-∞, -1) and (1,∞)

Decreasing is where it goes down

We are decreasing from ( -1,1)

The incorrect statement is decreasing from (-∞, -1)

a light switch works 25% of the time, how many times does it not work if switched on 64 times in a week
alexira [117]
25% of 64 is 16
\frac{25}{100}  =  \frac{x}{64}  \\ x =  \frac{64 \times 25}{100}  =  \frac{1600}{100}  = 16
it will work properly 16 times
64 - 16 = 48
it will not work 48 times
hope this helps

If you deposit $1000 in a savings account with an interest rate of r compounded annually, then the balance in the account after
Sedaia [141]

Answer:

B

Step-by-step explanation:

Our equation is as follows, B(c)=1000(1+r)^3. We are being asked to manipulate the equation and have it be r equals in order to solve for an interest rate when given a balance B. To solve the equation for the variable r, we must isolate r by completing order of operations or PEMDAS backwards.

SADMEP allows us to undo subtraction, addition, and etc in the correct order. We have no subtraction or addition outside of more complex operations. So we move to multiplication or division.

We divide both sides by 1000.

\frac{B}{1000} =\frac{1000(1+r)^{3} }{1000}

We simplify the right side.

\frac{B}{1000} =(1+r)^{3}

We need to now undo the exponent of 3 by using the inverse, a cube root.

\sqrt[3]{\frac{B}{1000}} =\sqrt[3]{(1+r)^{3}}

We simplify the right side.

\sqrt[3]{\frac{B}{1000}} =(1+r)

We subtract 1 to both sides to get r alone.

-1+\sqrt[3]{\frac{B}{1000}} =r

For our last step, we simplify the denominator of the root because 10*10*10=1000.

-1+\frac{\sqrt[3]{b} }{10} =r

This is answer choice b.
