A car travels along a straight road for 30 seconds starting at time t = 0. Its acceleration in ft/sec2 is given by the linear gr

I am Lyosha [343]

From an acceleration-time graph, you can work out the area under the graph to find the velocity. There are two triangles on the graph as shown below. The total area of the triangles are

$\frac{(10)(10)}{2}+ \frac{(20)(20)}{2}=250 ft/sec^{2}$

Hence, the distance is 250×30=7500 ft

{3x=7y=5<br> {5x-2y=-19

Anton [14]

Answer:

(-3, 2)

Step-by-step explanation:

{3x=7y=5

{5x-2y=-19

solve....

maybe it was 3x + 7y = 5

and 5x - 2y = -19

2*(3x + 7y = 5)

7*(5x - 2y = -19)

-------------

6x + 14y = 10

35x -14y = -133

41x = -123

x = -3

y = ...

5*(-3) - 2y = -19

-15 - 2y = -19

2y = 4

y = 2

(-3, 2)

Determine if the equation is linear. If so, graph the function.

musickatia [10]

Answer:

The equation is not linear

Step-by-step explanation:

You are given the equation

$\dfrac{2}{x}+\dfrac{y}{4}=\dfrac{3}{2}$

Express y in terms of x:

$\dfrac{y}{4}=\dfrac{3}{2}-\dfrac{2}{x}\\ \\\dfrac{y}{4}=\dfrac{3x-4}{2x}\\ \\y=4\cdot \dfrac{3x-4}{2x}\\ \\y=\dfrac{6x-8}{x}$

The linear function must of form

$y=mx+b,$

where m and b are real numbers.

Your function is not of this form, so this is not a linear function.

Each vertical cross-section of the triangular

Blizzard [7]

Answer:

The vertical height is $h=3\ units$

Step-by-step explanation:

we know that

In the right triangle ABC

see the attached figure

To find the height h apply the Pythagoras Theorem

$c^{2}=a^{2}+b^{2}$

we have

$c=AB=3\sqrt{2}\ units$

$a=BC=6/2=3\ units$

$b=AC=h\ units$

substitute

$(3\sqrt{2})^{2}=3^{2}+h^{2}$

$18=9+h^{2}$

$h^{2}=18-9=9$

$h=3\ units$
