Step-by-step explanation:

sinA= BC/AC

= 24/26

= 12/13

cosA= AC/AB

= 10/26

= 5/13

tanA= BC/AC

=24/10

= 12/5

Answer:

B. 0.03110

Step-by-step explanation:

Given

Probability of Hit = 60%

Required

Determine the probability that he misses at 6th throw

Represent Probability of Hit with P

$P = 60\%$

Convert to decimal

$P = 0,6$

Next; Determine the Probability of Miss (q)

Opposite probabilities add up to 1;

So,

$p + q = 1$

$q = 1 - p$

Substitute 0.6 for p

$q = 1 - 0.6$

$q = 0.4$

Next,is to determine the required probability;

Since, he's expected to miss the 6th throw, the probability is:

$Probability = p^5 * q$

$Probability = 0.6^5 * 0.4$

$Probability = 0.031104$

Hence;

A triangle has two constant sides of length 5 feet and 7 feet. The angle between these two sides is increasing at a rate of 0.9

o-na [289]

Answer: $12.74 ft^2/s$

Step-by-step explanation:

Given

Two sides of triangle of sides 5 ft and 7 ft

and angle between them is increasing at a rate of 0.9 radians per second

let $\theta$ is the angle between them thus

Area of triangle when two sides and angle between them is given

$A=\frac{ab\sin C}{2}$

$A=\frac{5\times 7\times \sin \theta }{2}$

Differentiate w.r.t time

$\frac{\mathrm{d} A}{\mathrm{d} t}=\frac{35\cos theta }{2}\times \frac{\mathrm{d} \theta }{\mathrm{d} t}$

at $\theta =\frac{\pi }{5}$

$\frac{\mathrm{d} A}{\mathrm{d} t}=\frac{35\times cos(\frac{\pi }{5})}{2}\times 0.9$

$\frac{\mathrm{d} A}{\mathrm{d} t}=12.74 ft^2/s$

If a car is traveling 92 feet per second, how many miles per minute is it traveling?

Jobisdone [24]

It’s A because 92 times 60 is 5520 divide that by the conversion of miles to a foot which is 5280 so 5520 divided by 5280 equals 1.045 or 1.05
