Distribute -3 to parenthasees
-3(r+9)=-3r-27

now we have
-3r-27=-32
add 27 to both sides
-3r+27-27=27-32
-3r+0=-5
-3r=-5
divide both sides by -3
r=-5/-3
r=5/3

4. A rectangle is inscribed into a circle. The rectangle is cut along one of its diagonals and reflected across that diagonal to
klio [65]

Answer:

The diagrams below explain the process with angles.

Step-by-step explanation:

In figure 1, a rectangle is drawn in the circle.

Since the acute angle being drawn by the hypotenuse is 40 degree in figure 2, thus we can say the other angle will be 50 degrees.

In figure 3, the rectangle is cut across its diagonal to form a kite shaped entity within the circle.

Now we know that m∠BDE = 40° = m∠ADB.

Also, m∠A = m∠E = 90°

Thus, m∠EBD = m∠ABD = 50° ⇒ m∠B = 100°

Also, m∠ADE = 80° ANSWER

A new shopping mall records 150 total shoppers on their first day of business. Each day after that, the number of shoppers is 15
Wewaii [24]

The number of shoppers is an illustration of an exponential function.

The expression for the number of shoppers is: \mathbf{f(n) = 150(1.15)^n}

The given parameters are:

<em />\mathbf{a = 150}<em> -- the number of shoppers on the first day of business</em>

<em />\mathbf{r = 15\%}<em> --- the rate</em>

<em />

Because, the number of shoppers <em>increases each day</em>, the number of shopper on a certain day is:

\mathbf{f(n) = a \times (1 + r)^n}

Substitute 15% for r

\mathbf{f(n) = a \times (1 + 15\%)^n}

Express percentage as decimal

\mathbf{f(n) = a \times (1 + 0.15)^n}

\mathbf{f(n) = a \times (1.15)^n}

Substitute 150 for a

\mathbf{f(n) = 150 \times (1.15)^n}

\mathbf{f(n) = 150(1.15)^n}

Hence, the expression for the number of shoppers is: \mathbf{f(n) = 150(1.15)^n}
