PLEASE HELP ILL GIVE YOU BRAINLIEST Water boils at different temperatures at different elevations. The boiling temperature of water is 212°F at sea level (0 feet) but drops about 1.72°F for every 1,000 feet of elevation. Write a formula for the boiling point at a given elevation. Then solve the formula for the elevation when the boiling point for water is 190°F.
Determine a formula for the boiling point b, in degrees Fahrenheit, at elevation h, in feet.

Formula:

Elevation at 190 degrees is about 12,790.7 feet

Step-by-step explanation:

since 1.72 degrees are lost for every 1000 feet, we can say:

for every feet, 1.72/1000 = 0.00172 degrees are lost. That is the slope of the function.

Now, to find the y-intercept, we need to know at elevation (h=0), how much is boiling point?

That is 212, so this is y-intercept.

The equation would be

y = mx + b

Where m is the slope and b is the y-intercept

So,

we can write:

y = -0.00172x+212

Changing variables:

b = -0.00172h + 212

To find elevation when boiling point is 190, we put 190 into b and solve for h:

190 = -0.00172h + 212

0.00172h = 22

h=12,790.7 feet

Step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

answer: 0.1,0.85
