Find c to two decimal places and find the measure of angle B. Angle A = 58°, Side AC = 5, Side BC = 8, Find side C. Angle C is 9

KATRIN_1 [288]

Answer:

c = 9.43
m∠B = 32°

Step-by-step explanation:

Side c = AB can be found using the Pythagorean theorem:

c² = a² + b² = 8² +5² = 89

c = √89 ≈ 9.43

Angle B is the complement of angle A, so is ...

B = 90° -A = 90° -58° = 32°

c is approximately 9.43; the measure of angle B is 32°.

Calculate time period of a simple pendulum if it takes 72 seconds to complete 24 oscillations

Anvisha [2.4K]

Answer:

The time period of a simple pendulum if it takes 72 seconds to complete 24 oscillation will be 3 seconds.

Step-by-step explanation:

Total number of oscillations = 24

Time taken to complete 24 oscillations = 2 seconds

So, the frequency 'f' of the simple pendulum will be:

$f=\frac{24}{72}$

$f=\frac{1}{3}$

Let 'T' be the time period.

$T=\frac{1}{f}$

$T=\frac{1}{\frac{1}{3}}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{1}{\frac{b}{c}}=\frac{c}{b}$

$T=\frac{3}{1}$

$T=3$

Therefore, the time period of a simple pendulum if it takes 72 seconds to complete 24 oscillation will be 3 seconds.

Gary's jogging average speed is represented by the equation y=3.5x where y is the distance in miles and x is the time in hours.

Softa [21]

Answer:

Gary can go 4.9 miles in 84 minutes.

Step-by-step explanation:

First, you need to determine the amount of hours 84 minutes represent considering that 60 minutes are equal to an hour:

60 minutes → 1 hour

84 minutes → x

x=(84*1)/60=1.4 hours

Now, 1.4 hours would be the time which is x and you can replace the value on the formula to find y:

y=3.5x

y=3.5(1.4)

y=4.9

According to this, the answer is that Gary can go 4.9 miles in 84 minutes.
