2. A square has an area of 64 square inches. It is enlarged by a scale factorof Ž. What is the length of one side of the new squ

maw [93]

Following the setps we have that

$\begin{gathered} n\cdot n=64 \\ n^2=64 \\ n=\sqrt[]{64}=8 \end{gathered}$

the lengths of the sides of the original square is 8 inches each one. Now we are going to find the lengths of the sides of the new square following the step 2

$8\cdot\frac{3}{2}=\frac{24}{2}=12$

the lengths of the sides of new square is 12 inches each one.

A piece of land was worth $63,710.1 last year. This year, the cost of land has increased by 12%. How much is the land worth now?

Bingel [31]

Answer:

$71,355

Step-by-step explanation:

The value of the land was 100% of the value of the land.

The value went up by 12%. 100% + 12% = 112%. Now the value of the land is 112% of the original value.

112% of $63,710.1 = 1.12 × $63,710.1 = $71,355

The amount of radioactive uranium changes with time. The table below shows the amount of radioactive uranium f(t) left after tim

aniked [119]

Answer:

$f(t) = 100(0.25)^t$

Step-by-step explanation:

The general exponential function is,

$f(t)=ab^t$

The points given in the table are,

$(0,100),(0.5,50),(1,25)$

Putting $(0,100),(1,25)$ in the general equation, we get

$\Rightarrow 100=ab^0$

$\Rightarrow a=100$

And

$\Rightarrow 25=ab^{1}$

$\Rightarrow ab=25$

Putting the value of a,

$\Rightarrow 100b=25$

$\Rightarrow b=0.25$

Now the exponential function becomes,

$f(t) = 100(0.25)^t$
