A square has a perimeter of 12 yd. What is the length of each side?

Lena [83]

Answer:

Length of side of square is 3 yd.

$~$

Step-by-step explanation:

Let the side of square be 's'. We know that Perimeter of square is 4 × Side. By substituting values in the formula we can find the required side.

$~$

$:\implies \sf 4 × s=Perimeter \: of \: square$

$~$

$:\implies \sf \: \: \: 4 × s = 12$

$~$

$:\implies \sf \: \: \: s = \dfrac{12}{4}$

$~$

$:\implies \bf \: \: \: Side = 3 yd.$

$~$

$\therefore \:$ Length of side of square is 3 yd.

For the function f(t) =Pe^rt , if P= 7 and r= 0.07 then what is the value of f(7) to the nearest tenth?

White raven [17]

Answer:

A. 11.4

Step-by-step explanation:

$f(t) = P e^{rt}$

Data:

P = 7

r = 0.07

Calculation:

$\begin{array}{rcl}f(t) & = &Pe^{rt}\\f(7)& = & 7 e^{(0.07 \times 7)}\\ & = & 7 e^{0.49}\\& \approx & 7 \times 1.632\\ & \approx & \mathbf{11.4}\\\end{array}$
