scarlet is trying to find the height of a dam. she stands 90 meters away from the dam and records the angle of elevation to the

Harlamova29_29 [7]

Make a drawing with a right triangle.

The opposite side, y, is the height of the dam less 1.65 m

The base or adjacent side is 90 m

The angle between the two sides is 90 m.

Then tan (26) = y / 90

y = 90 tan(26) = 90 (0.4877) = 43.90 m

The height of the dam is 43.90m + 1.65m = 45.55 m

For a ride on a rental scooter, John paid an $8 fee to start the scooter plus 6 cents per minute of the ride. The total bill for

enot [183]

The linear equation is $8+0.06x=19.94$ and John rode the scooter for $199$ minutes.

Fee to start the scooter $=$ $ $8$ .

Fee to ride per minute $= 6$ cents $=$ $ $0.06$ .

Total bill $=$ $ $19.94$ .

Let $x$ be the minutes for which he rides the scooter.

The linear equation is formed as:

$8+0.06x=19.94$

$0.06x=19.94-8$

$0.06x=11.94$

$x=199$ minutes.

So, John rode the scooter for $199$ minutes.

Write the slope intercept form of the equation of the line through the given points. (5,-1) and (-5,2)

Lelu [443]

Answer:

$y=-\frac{3}{10} x+\frac{1}{2}$ or $-\frac{3}{10}$

Step-by-step explanation:

first use the y2-y1/x2-x1 formula then use y=mx+b after

plug in 2 for y2 and -1 for y1

plug in -5 for x2 and 5 for x1

$\frac{2-(-1)}{-5-5}$ =

2+1=3

-5-5=-10

$-\frac{3}{10}$ is ur slope

_____________________

this is the y=mx+b formula *extra info ig*

i usually use the first point for this but u can use watever point u want

plug in 5 for x

plug in -1 for y

and plug -3/10 for m

-1=-3/10(5)+b

-3/10*5=-3/2

-1=-3/2+b

add -3/2 on both sides

-1+3/2=1/2

1/2=b and b is ur y-intercept

y=-3/10x+1/2

hope this helps
