The sin(4π/5) must be positive since 0 < 4π/5 < π. So C is the only approximate value.
What is trigonometric series?A trigonometric series is convergent to a function f(x) on the interval [0,2π ]which is identically zero or nonzero at most points, then the coefficients of the series are all zero.
The first five terms in the series expansion of sin(x) are
sin(x) ≈ x - x ³/3! + x ⁵/5! - x ⁷/7! + x ⁹/9!
Now let x = 4π/5:
sin(4π/5) ≈ 0.5884
Thus, approximate value of trigonometric series to four decimal places is 0.5884.

Which expression is equivalent to (2x + 9)² - (x-7)?
Answer:
[tex]\boxed{\bf B. \: 4 {x}^{2} + 35x+88}[/tex]
Explanation:
In order to find what expression is equivalent to (2x + 9)² - (x-7), we'll use the binomial theorem (a+b)^2 =a^2+2ab+b^2 to expand (2x+9).
[tex]\bf 4 {x}^{2} +36x+81 - (x - 7)[/tex]
[tex]\bf 4 {x}^{2} +36x+81 - x+7[/tex]
Let's combine like terms. 36x + (-x) = 35x
[tex]\bf 4 {x}^{2} + 35x+81+7[/tex]
Add numbers. 81 + 7 = 88
[tex]\bf 4 {x}^{2} + 35x+88[/tex]
Therefore, our answer is Option B.

Initially, a ball has an angular velocity of 5.0 rad/s counterclockwise. sometime later, after rotating through a total angle of 5.5 radians, the ball has an angular velocity of 1.5 rad/s clockwise. what is the angular acceleration?
Explanation:
it is not necessary to know for this question, but FYI
1 rad = 180/pi = 57.29577951...°
in essence it describes the arc angle of the arc with the length = radius.
anyway,
we are only dealing with relative sizes here all expressed in radians.
the original spin rate or angular velocity is 5.0 rad/sec.
that means in 1 second it spins by 5 radians (a point on the surface moves by that many degrees).
remember, acceleration is speed/time or distance/time².
then we measure again - after the ball moved by a total angle of 5.5 radians. so, it was longer than 1 second.
so, how much time passed ?
time = distance / speed
5.5 rad / 5.0 rad /1 sec = 1 sec × 5.5 rad / 1×5.0 rad =
= 5.5 sec / 5.0 = 1.1 sec
so, the acceleration was
1.5 - 5.0 = -3.5 rad/(1.1 sec)² = -3.5 rad / 1.21 sec² =
= -2.892561983... rad/sec²
Altitudes $\overline{ad}$ and $\overline{be}$ of acute triangle $abc$ intersect at point $h$. if $\angle ahb = 128^\circ$ and $\angle bah = 28^\circ$, then what is $\angle hca$ in degrees?
The Angle HCA is equal to 52°. This is arrived at using the knowledge of the Total value of Angles in a Triangle and the Total Value of Angles in a Polygon.
What other principles were used to arrive at the answer?
The other principles of mathematics that were used to arrive at the above answer are:
Total Angles on a straight line; Total Angles on a point; and Line segments.What are the Steps to the Solution?Step 1 - Recall that we have been given Angles AHB and BAH to be 128° and 28° respectively.
We also know that:
The sum of angles in a triangle is 180°;...................AThe sum of angles on a straight line is 180°;.........BThe sum of angles in a polygon is 360°; while.....CThe total sum of angles at a point is 360°.............DSince A...therefore:
When ∠AHB (128°) and ∠BAH are taken from 180° we have DBA = ∠28°.
By observation, we can deduce that ∠BDE, ∠CDH, ∠CEH and ∠AEH are all right-angled triangles.
Using the above, we are able to repeat this process of solving for each angle until we have ∠HCA.
To verify that our answer is correct, recall that sum of angles in a polygon is 360°
That means:
∠BDA + ∠DHE + ∠CEH + ∠HCA = 360°
That is, 90+ 128 + 90 + 52 = 360°

Think about the benefits of each type of federal student loan and then discuss how you feel about taking out student loans to pay for college. Consider the options that you have for funding your education besides taking out loans.
Answer:
Federal student loans generally have lower interest rates than private loans. Rates for new federal loans are also fixed, meaning they'll stay the same during your entire loan term. Private loans frequently offer variable rates, which increase whenever the Federal Reserve raises the interest rate benchmark.

If a concession owner pays $0.50 per pretzel, and it costs the owner $1.00 to have the pretzel prepared and served, what should the owner charge per pretzel if he wants cost to be 60% of the price?
The owner should charge an amount of $2.50 per pretzel, if the cost price of 60% is desired.
What is cost price?The cost borne by a producer to manufacture or produce such goods and sell them at a higher price is known as the cost price. In this case, the cost price if $1.50 per pretzel.
