Answer:

#1 THE LENGTH IS 24 FT, WIDTH IS 12 FT..... #2 DISTANCE IS 7

Step-by-step explanation:

ON PROBLEM ONE ITS SAYING FOR EVERY 1 CM ITS EQUALY TO 4 FEET, SO MULTIPLY 6CM*4 FEET OR 1*4 + 1*4 + 1*4 + 1*4 + 1*4 +1*4=24

YOU DO THE SAME FOR THE WIDTH WHICH WOULD BE 3CM*4FT=12

ITS THE SAME FOR THE SECOND PROBLEM TO YOUD DO 2*3 1/2=7

Step-by-step explanation:

I'm going to answer number one.

The figure you are given is a scale copy- a smaller version of the real thing with the same ratio of measurements. So, since we have a 6cm length and 1 cm is supposed to be 4 feet, multiply 6 by 4 to get 24 feet as the real length.

We have 3 cm as width, so multiply that by 4 to get 12 feet as the real width

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:

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

I REALLY NEED HELP PLEASE!!

part A)

$\bf \begin{array}{ccllll}
hours(x)&velocity(y)\\
-----&-----\\
1&6\\
3&2
\end{array}\\\\
-------------------------------\\\\$

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 1}}\quad ,&{{ 6}})\quad 
% (c,d)
&({{ 3}}\quad ,&{{ 2}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{2-6}{3-1}\implies \cfrac{-4}{2}\implies -2$

$\bf y-{{ y_1}}={{ m}}(x-{{ x_1}})\implies y-6=-2(x-1)\\
\left. \qquad \right. \uparrow\\
\textit{point-slope form}
\\\\\\
y-6=-2x+2\implies y=-2x+2+6\implies \boxed{y=-2x+8}$

part B)

well, we know y = -2x+8.... so.. what's the runner's velocity after 5hours? well, x = 5, thus y = -2(5) +8 ---> y = -2

to graph it, well, is a LINEar equation, meaning the graph is a LINE, and to graph a line, all you need is two points, and by now, you have more than two.. so graph it away.
