Lester wants to share 24 marbles between his two friends , Fester and Felix in the ratio 3 : 5.

ankoles [38]

Answer:

 Solution,

 $area \\ = 9 \times 6 + \frac{1}{2} \times (6 + 11) \times 6 \\ = 54 + \frac{1}{2} \times 17 \times 6 \\ = 54 + 51 \\ = 105 \: {cm}^{2}$ 

hope this helps...

Good luck on your assignment..

A golf ball is hit from the ground with an initial velocity of 208 ft./s. assume the starting height of the ball is 0 feet. how

V125BC [204]

Check the picture below, it hits the ground at y = 0

thus

$\bf \qquad \textit{initial velocity}\\\\
\begin{array}{llll}
\qquad \textit{in feet}\\\\
h(t) = -16t^2+v_ot+h_o
\end{array} 
\quad 
\begin{cases}
v_o=\textit{initial velocity of the object}\\
h_o=\textit{initial height of the object}\\
h=\textit{height of the object at "t" seconds}\\
----------\\
v_o=208\\
h_o=0
\end{cases}$

$\bf h(t)=-16t^2+208t+0\implies h(t)=-16t^2+208t\impliedby 
\begin{array}{llll}
\textit{now let's}\\
make\\ h(t)=0
\end{array}
\\\\\\
0=-16t^2+208t\implies 0=t(208-16t)
\\\\\\
\begin{cases}
0=t\\
----------\\
0=208-16t\\
\qquad 16t=208\\
\qquad t=\frac{208}{16}
\end{cases}$

and I'm sure you know how much that is

it hits it at two points, as you notice in the picture, at 0 seconds, when it's first hit and goes up, and when it falls down.

Determine whether the three points A(-2,-1), B(0,4) and C(2,9) all line on the same line.

sashaice [31]

All three of them do exist on the line y = 2.5x + 4

In order to find the answer to this question, start by finding the line for two points. For this example, we'll use A and C.

First we need to find the slope.
(y1 - y2)/(x1 - x2)
(9 - -1)/(2 - -2)
(9 + 1)/(2 + 2)
10/4
2.5

Now using slope intercept form and point A, we can determine the intercept of that line as well.

y = mx + b
-1 = 2.5(-2) + b
-1 = -5 + b
4 = b

So now we know A and C form the line y = 2.5x + 4. We can then check if B fits that line.

y = 2.5x + 4
4 = 2.5(0) + 4
4 = 0 + 4
4 = 4 (TRUE)

Therefore, it also falls on that line.

James rode his bike for 0.65 hours and traveled 8.45 km what is his speed?

skelet666 [1.2K]

S=d/t
s=8.45km/0.65hr
s= 13km/hr

Therefore the speed is 13km/h.

Hope that helps :)
