Answer:

73 degrees

Step-by-step explanation:

Given that the temperature during a day can be modeled by a sinusoid.

At 4 am. lowest = 53 deg and at 4 pm highest = 99 deg

Amplitude = (99-53)/2 = 23

Mean temp = 76 deg

If 4 am is taken as t =0 then we have middle temp = 46 degrees at 10 a.m.

Hence equation would be of the form

T(t) =23 sin (pi t/12)+53 where T is the temperature and t is time in hours from 4 a.m.

At 8 am t =4

So T(4) = 23 sin pi/3 +53  = 19.92+53  =72.92

Nearly 73 degrees

The answer is
h= -41.36

You first multiply -8.1(-0.4) and you get 3.24.
Then you subtract 3.24 - 44.6 to get h.

Find the angle with the smallest measure in △ VUW. Name the angle using three letters
Nimfa-mama [501]

Answer:

∠VUW

Step-by-step explanation:

A triangle is a three sided polygon with three angles. Types of triangles are obtuse, scalene, isosceles, equilateral and so on.

In triangle VUW, since VU = WU, hence it is an isosceles triangle. In an isosceles triangle, two sides of the triangle are equal.

The size of an angle depends on its opposite side, the higher the opposite side the higher the angle. Since In triangle VUW, VU = 9, WU = 9, VW = 5. Since VW is the smallest side, the angle opposite to VW is the smallest angle.

Hence the smallest angle = ∠VUW
