Answer:

a) 3/4

b) 3/4

c) 3/4

d) all are 3/4

Step-by-step explanation:

The slope of a line is defined as the change in y divided by the change in x. This is often referred to as "rise over run":

slope = Δy/Δx = "rise"/"run"

The triangles are drawn against the line so that you can use them to identify values of "rise" (vertical change) and "run" (horizontal change) between two points on the line.

The slope of the segment AC is found by dividing the "rise" (BC = 3) by the "run"(AB = 4)

slope of AC = BC/AB = 3/4

The slope of FH is similarly computed. Here, it is made a little more difficult, because you must estimate the value of GH.

slope of FH = GH/FG = 1.5/2 = 0.75 = 3/4

The slope of CE is ...

slope of CE = DE/CD = 6/8 = 3/4

The slopes in a), b), c) are all 3/4.

You can reasonably draw the conclusion that the slope of a line is the same everywhere. A line has constant slope.

Answer:

No, it is D.

Step-by-step explanation:

<em>It can not be A or C, because length can not be negative</em>

Because the y is the same, you only have to <em>count the distance of the x-axises</em>.

4 - (-3) is 7 units, which is D.

An object is thrown straight up from the top of a 100-foot platform at a velocity of 48 feet per second. The height h(t) of the

julsineya [31]

Answer:

The maximum height is 136 ft

The time it takes to achieve this height is 1.5 s.

Explanation:

<u>1. Function for the height (given):</u>

$h(t)=-16t^2+48t+100$

<u />

<u>2. Type of function</u>

That is a quadatic function, whose graph is a parabola that opens downward.

The maximum of the function, i.e. the maximum height, is the vertex of the parabola.

The vertex of a parabola with the genral equation $y=ax^2+bx+c$ is at the x-coordinate

$x=-b/(2a)$

<u>3. Time to achieve the maximum height</u>

Substitute b with 48 and a with - 16:

$t=-48/(2(-16))=48/32=3/2=1.5$

Then, time when the object achieves the maximum height it 1.5s

<u />

<u>4. Maximum height:</u>

Replace t with 1.5 in the equation, to find the maximum height, h(1.5)

$h(1.5)=-16(1.5)^2+48(1.5)+100=136$

Then, the maximum height is 136 ft
