Cerrena [4.2K]

Answer:

noun

1.

a surface of which one end or side is at a higher level than another; a rising or falling surface.

Step-by-step explanation:

steepness

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x)

step one: identify two points on the line

step two: select one to be (x1,y1) and the other to be (x2,y2)

step three: use the slope equation calulate slope

2x-3=8+7(+3)

2y-3(+3)=8x+7(+3)

2y=8x+10

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

2y=8x+10

y=4x+5

1. A slide 3.5 m long makes an angle of 28° with
balu736 [363]

Answer: Option d.

Step-by-step explanation:

Draw a right triangle using the data given in the exercise (Observe the picture attached)

Let be "h" the height in meters from the ground to the top of the slide.

You need to use the following Trigonometric Identity:

sin\alpha =\frac{opposite}{hypotenuse}

In this case you can identify that:

\alpha =28\°\\oppossite=h\\hypotenuse=3.5

Therefore, susbstituting values into sin\alpha =\frac{opposite}{hypotenuse} and solving for "h", you get:

sin(28\°) =\frac{h}{3.5}\\\\(3.5)(sin(28\°))=h\\\\h=1.64
