In ΔPQR, the measure of ∠R=90°, QR = 8 feet, and RP = 3.9 feet. Find the measure of ∠P to the nearest degree.

Answer:

64°

Step-by-step explanation:

Check the attachment for the diagram. Since the triangle has one of its angle as 90°, it is a right angled triangle.

Using the SOH CAH TOA trigonometry ratios:

Since ∠P is opposite to side QR,

QR = opposite side = 8ft

RP = adjacent side = 3.9ft

According to TOA

Tan∠P = Opposite/Adjacent = QR/RP

Tan∠P = 8/3.9

Tan∠P = 2.05

∠P = arctan 2.051

∠P = 64°

The cross section of a parabolic reflector has a vertical axis of symmetry with its vertex at (0,0). The focus of the reflector
sattari [20]

Answer:

1.26 feets

Step-by-step explanation:

Given the following :

Vertex (0, 0)

Focus of reflector = 6 feets

Extension = 5.5 feets

Equation to obtain conic section of a parabola:

(x - h)² = 4p(y - k)

Vertex (0, 0)

h =0 ; k = 0, p = 6, x = 5.5

(5.5 - 0)² = 4*6(y - 0)

30.25 - 0 = 24(y - 0)

30.25 = 24y

y = 30.25 / 24

y = 1.26

Hence, depth of reflector = 1.26 feets

Three runners — Andy, Blaise, and Susie — were competing in a 100-meter race. When Andy reached the finish line, Blaise was 10 m
nikitadnepr [17]

Answer:

20 meters.

Step-by-step explanation:

Well, Andy had finished the 100 meter race before everyone else. This obviously means that he/she had already ran 100 meters. Blaise was 10 meters behind Andy meaning he was at 90 meters. Then Susie was 10 meters behind Susie, meaning Susie was at 80 meters while Andy was at 100. Finally 100-80=20

or

10+10=20
