Answer:
[tex]{ \boxed{ \tt{trig \: identity : { \bf{ { \cos}^{2} A + { \sin }^{2} A = 1}}}}} \\ \therefore \: { \green{ \tt{ \sin A = \sqrt{1 - { \cos }^{2}A } }}} \\ \sin A = \sqrt{1 - {( \frac{3}{4}) }^{2} } \\ \sin A = \frac{ \sqrt{7} }{4} = 0.661 \\ \\ { \green{ \tt{ \tan A = \frac{ \sin A }{ \cos A} }}} \\ \tan(A ) = \frac{ \frac{ \sqrt{7} }{4} }{ \frac{3}{4} } = \frac{ \sqrt{7} }{3} = 0.882 \\ \\ { \underline{ \blue{ \tt{ becker \: jnr}}}}[/tex]
The exact values of sin (A) and tan ( A) are 0.661 and 0.882 respectively.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
We have been given that 270º < AS 360° and cos(A)= 3/4.
We are required the exact values of sin (A) and tan ( A)
Since, cos(A)= 3/4.
cos ²A + sin² A = 1
sin A = √ 1- cos ²A
sin A = √ 1- (3/4) ²
Sin A = 0.661
Tan A = sin A / Cos A
Tan A = 0.661/ 3/4 = 0.882
Hence, the exact values of sin (A) and tan ( A) are 0.661 and 0.882 respectively.

Plot the image of point B under a reflection across line m
Answer:
Step-by-step explanation:
If a point (x, y) is reflected across a line, image of the point will be at the same distance from the line as the original point is.
In fact line of reflection works like a mirror.
In the figure attached,
Distance of point B from the line 'm' = 6 units
Therefore, distance of the image point B' from line 'm' = 6 units (on opposite side of the line of reflection)

The amount of time needed to complete a job, t, varies inversely with the number of workers, w. If 10 workers can complete a job in 20 minutes, how many minutes would it take 5 workers?
The amount of time needed to complete a job by 5 workers is
40 minutes.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
The amount of time needed to complete a job, t, varies inversely with the number of workers.
Number of workers = W
Time to complete 1 work = T
This means,
T = 1 / W
W = 1 / T
10 workers can complete a job in 20 minutes.
This can be written as:
10 W = 1 / 20
Divide 10 on both sides.
1 W = 1 / 200
This means,
1 worker can complete a job in 200 minutes.
Now,
1 W = 1/ 200
Multiply 5 on both sides.
5 W = 5/200
5 W = 1 / 40
This means 5 workers will take 40 minutes to complete the work.
Thus,
The amount of time needed to complete a job by 5 workers is
40 minutes.

The heights of students in a class are normally distributed with mean 63 inches and standard deviation 4 inches. Use the Empirical Rule to determine the interval that contains the middle 68% of the heights.
Answer:
The interval that contains the middle 68% of the heights is between 59 and 67 inches.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 63, standard deviation of 4.
The interval that contains the middle 68% of the heights.
By the Empirical rule, within 1 standard deviation of the mean. So
63 - 4 = 59
63 + 4 = 67
The interval that contains the middle 68% of the heights is between 59 and 67 inches.

Niu earned $312 on an investment of $800. How much would $1100 have earned in the same
investment?
Answer:
429
Step-by-step explanation:
312/800 = .39
1100 x .39 = 429
Answer:
$429
Step-by-step explanation:
--------------------
[tex]\frac{312}{800} =\frac{x}{100}[/tex]
Cross multiply
[tex]800x=31200[/tex]
Divide both sides by 800
[tex]x=39[/tex]
So, Niu earned 39% on the investment of $800
So, let's find out how much $1,100 would have earned him in the same investment.
--------------->>>>
[tex]\frac{x}{1100}=\frac{39}{100}[/tex]
Cross multiply
[tex]100x=42900[/tex]
Divide both sides by 100
[tex]x=429[/tex]
--------------------
This means that Niu $1,100 would have earned Niu $429 in the same investment.

Step-by-step explanation:
consider the polygon shown. Determine the value of y. PLEASE HELP
Answer:
y = 64°
Step-by-step explanation:
From the picture attached,
m(∠E) = 90°
m(∠E) = m(∠D)
m(∠B) + 67° = 180° [pair of linear angles]
m(∠B) = 113°
m(∠C) + 75° = 180°
m(∠C) = 180° - 75°
= 105°
Since, sum of interior angles of a polygon = (n - 2) × 180°
Here, n = number of sides
For n = 5,
Sum of interior angles = (5 - 2) × 180°
= 540°
m(∠A) + m(∠B) + m(∠C) + m(∠D) + m(∠E) = 540°
m(∠A) + 113° + 105° + m(∠D) + 90° = 540°
(m∠D) + m(∠D) = 540 - 308 [Since, m(∠A) = m(∠D)]
2(m∠D) = 232
m(∠D) = 116°
m(∠D) + y° = 180° [Linear pair of angles]
116 + y = 180
y = 64°

Use the value 3.14 for , and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.
Answer:
381 cm³
Step-by-step explanation:
Volume of the pot = volume of a cylinder
Volume of the pot = πr²h
Where,
π = 3.14
radius (r) = 4.5 cm
h = 6 cm
Substitute
Volume of the pot = 3.14*4.5²*6
Volume of the pot = 381.51 ≈ 381 cm³ (nearest whole number)
