Answer:

<h2><u>Graph A. </u></h2>

Step-by-step explanation:

Since you are looking for a graph that shows a function, answer A has to be correct. If you look at graph B, C and D, none of these are functions

You can check if a graph shows a function using the vertical line test. Make a vertical line on any x value and if it passes through 2 or more lines, it is NOT a function

Graphically determine the slopes of the line segments that create triangle ACD shown below. Write your final slopes in simplest

a_sh-v [17]

Answer:

Step-by-step explanation:

From the graph attached,

Coordinates of points A, C and D are,

A(-2, -7), C(-6, 7) and D(9, 2)

Slope of AD = $\frac{y_2-y_1}{x_2-x_1}$

= $\frac{-7-2}{-2-9}$

= $\frac{9}{11}$

Slope of CD = $\frac{7-2}{-6-9}$

= $-\frac{1}{3}$

Slope of AC = $\frac{7-(-7)}{-6-(-2)}$

= $-\frac{14}{4}$

= $-\frac{7}{2}$

Lucas invested money in two accounts: one paying 3% interest and the other paying 5% interest. He invested $100 more in the 5% a

Anni [7]

He invested "a" at 3% and "b" at 5%

now, he invested 100 more in "b", so, whatever "a" may be, b = a + 100

now, how much is the interest yield of each? well
how much is 3% of a? well, (3/100) * a, or 0.03a
and 5% of b? well (5/100) * b, or 0.05b

now, we know the total yield was 53 bucks, thus 0.03a + 0.05b = 53

thus $\bf \begin{cases}
\boxed{b}=a+100\\
0.03a+0.05b=53\\
----------\\
0.03a+0.05\left( \boxed{a+100} \right)=53
\end{cases}$

solve for "a", to see how much was invested at 3%

what about "b"? well, b = a + 100

An object is moving in a horizontal direction only. The graph shows its velocity vs. time.

Naddik [55]

14) Distance= area under curve
=1/2*9*6= 27

15)dp/dt=F
m(v-u)/0.41=F
m(2u+u)/0.41= m*a
3u/0.41= 1/a
3/0.41= a/u= -7.31

16)v^2-u^2=-2gh
H(max)= 900/2*1.62= 278m
