Answer:

D. $432.84

Step-by-step explanation:

The average daily balance is the weighted sum of the balances. The weight in each case is the number of days the account had that balance.

adb = (7×745.00 +10×585.15 +7×245.20 +7×90.75)/(7+10+7+7)

= 13,418.15/31

= 432.84

Nia's average daily balance was $432.84.

Consider the graph f(x)=3 to the power of x. describe how to graph the transformation f(x-3)+2

Assoli18 [71]

Answer:

shift the graph horizontally to the right for 3 units and then shift vertically up 2 units

Step-by-step explanation:

f(x) = x³ vs f(x-3)+2

f(x-3) will shift the graph horizontally to the right for 3 units

+2: will shift vertically up 2 units

1 pt) find the average rate of change of the function over the given intervals. h(t)=\cot (t);

blondinia [14]

$\text{Consider the function}\\
\\
h(t)=\cot(t) \text{ on the interval }\left [ \frac{\pi}{4}, \ \frac{3\pi}{4} \right ]\\
\\
\text{we know that the average rate of change of a funtion f(x) over the }\\
\text{interval [a, b] is given by}\\
\\
f_{avg}=\frac{f(b)-f(a)}{b-a}\\
\\
\text{so using this, the average rate of change of the given function is}$

$h_{avg}=\frac{h\left ( \frac{3\pi}{4} \right )-h\left ( \frac{\pi}{4} \right )}{\frac{3\pi}{4}-\frac{\pi}{4}}\\
\\
=\frac{\cot \left ( \frac{3\pi}{4} \right )-\cot \left ( \frac{\pi}{4} \right )}{\frac{3\pi-\pi}{4}}\\
\\
=\frac{(-1)-(1)}{\frac{2\pi}{4}}\\
\\
=\frac{-2}{\frac{\pi}{2}}\\
\\
\text{Average rate of change of function}=\frac{-4}{\pi}$

The ratio of doves to parrots in a cage is 1 to 2. If there are 6 doves and parrots altogether then how many parrots are there?

Mama L [17]

There would be 2 doves and 4 parrots.

2 + 4 = the 6 in total, and the ratio between doves (2) and parrots (4) is 1 to 2 because the ratio of 2 to 4 is equal to 1 to 2.

A bag held 4 black marbles, 2 red marbles, and 6 white marbles. I drew a black marble and did not replace it. What is the probab

Helga [31]

Answer:

P (black marble) =3/11

Step-by-step explanation:

We need to find the total number of marbles

4 black marbles+ 2 red marbles+ 6 white marbles= 12 marbles

We take away a black marble and throw it away

3 black marbles+ 2 red marbles+ 6 white marbles= 11 marbles

The probability of drawing a black marble is

P (black marble) = black/total

=3/11
