Answer:

35.)   80

36.)   11

37.)   15

38.)   21

39.)   -9

40.)   -1

Step-by-step explanation:

In simplified terms the question is asking

35.)   g(f(-1)) =

         g(-9) = 80

36.)   f(g(2)) =

         f(3) = 11

37.)   g(f(0)) =

        g(-4) = 15

38.)   f(g(root6)) =

         f(5) = 21

39.)   f(g(0)) =

         f(-1) = -9

40.)   g(f(4/5)) =

         g(0) = -1

The diagram shows a sketch of a survey done by a civil engineering student .Find the value of x,giving your answer correct to 1
Hatshy [7]

You can do this by drawing one line through parallel to PQS to meet RQ at T

Now calculate length of RT:-

cos 70 = RT / 70 giving RT = 23.94m

sin 70 = ST/70 giving ST = 65.78 m

draw a line from S perpendicular to PQ to meet PQ at U.

PU = 110 - 65.78 = 44.22 m

tan 50 = SU / 44.22 giving SU = 52.70 m

TQ = SU = 52.70 m

So x = TQ + RT = 52.70 + 23.94 = 76.6 m to 1 dec place.

A repair company’s charge for repairing a certain type of copy machine fits the model y = 47.38 + 0.617x where y is the number o
Tems11 [23]

Answer: 36.66min

Step-by-step explanation:

y = 47.38 + 0.617x

where y is the number of dollars

x is the number of minutes on the job

Given a value of y = $70, then

We substitute y = $70 in the equation.

70 = 47.38 + 0.617x

22.62 = 0.617x

X = 22.62/0.617 = 36.66min

Greeley [361]

Answer:

Yes, the distance between the points would be 8

Step-by-step explanation:

Since the y is the same, you can just find the distance between 12 and 4

12-4=8

Find the measures of the angles of a triangle whose angles have a measure of x, 1/2x, and 1/6x. Also, what kind of triangle is i
Alexandra [31]

the sum of the angles in a triangle = 180°, thus

x + \frac{1}{2} x + \frac{1}{6} x = 180

multiply through by 6

6x + 3x + x = 1080

10x = 1080 ( divide both sides by 10 )

x = 108

the angles are 108°, 54° and 18°

Since all the angles are different and the largest is 108°

The triangle is an obtuse scalene triangle
