Answer:

  204 4/9 °C

Step-by-step explanation:

Put the number in the formula and do the arithmetic.

  °C = (5/9)(400 -32) = 5/9(368) = 204 4/9

The temperature in °C is 204 4/9.

A tree is growing on a hill. In an attempt to make the tree grow straight up, a 12-foot-long wire is attached to a tree at a poi
melisa1 [442]
For this case what we must do is use the law of cosines.
 We have then:
 12 ^ 2 = 6 ^ 2 + 10 ^ 2 - 2 * (6) * (10) cos (x)
 Clearing we have:
 cos (x) = (12 ^ 2- (6 ^ 2 + 10 ^ 2)) / (- 2 * (6) * (10))
 x = acos ((12 ^ 2- (6 ^ 2 + 10 ^ 2)) / (- 2 * (6) * (10)))
 x = 93.82 degrees
 Answer:
 
The tree is growing in relation to the hill at:
 
x = 93.82 degrees

Directions: Given the point and slope, write the equation of the line.<br> (4, 2); slope = 36
olga nikolaevna [1]

Answer:

y - 2 = 36(x - 4)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 36 and (a, b ) = (4, 2 ) , then

y - 2 = 36(x - 4) ← equation of line
