find the measure of the angle marked with a? Using the inverse trig functions. Round your answer to the nearest degree.
Answer: 52°
Step-by-step explanation:
[tex]\sin \theta=\dfrac{\text{side OPPOSITE of angle}}{\text{HYPOTENUSE}}\\\\\\\sin \theta =\dfrac{23}{29}\\\\\\.\quad \theta=\sin ^{-1}\bigg(\dfrac{23}{29}\bigg)\\\\\\.\quad \theta =52.47^o[/tex]
Rounded to the nearest degree: Ф = 52°
Step-by-step explanation:
Hey there!
Here;
The figure given is a Right angled triangle.
Let the unknown angle be a refrence angle.
Now,
p = 23
h = 29
In ratio of sin there is 'p' and 'h'. So, using sin ratio.
[tex] \sin( \alpha ) = \frac{p}{h} [/tex]
[tex] \sin( \alpha ) = \frac{23}{29} [/tex]
[tex] \alpha = { \sin}^{ - 1} (0.7931034)[/tex]
[tex] \alpha = 52.47°[/tex]
Therefore the the angle is 52°.

Correct Question:
Type the correct answer in the box. Use numerals instead of words. Consider this expression. [tex]\sqrt{a^2} - 7 + |b|[/tex] When a = 2 and b = -4, the value of the expression is
Answer:
[tex]\sqrt{a^2} - 7 + |b| = -1[/tex]
Step-by-step explanation:
Given
[tex]a=2[/tex]
[tex]b = -4[/tex]
Required
Determine [tex]\sqrt{a^2} - 7 + |b|[/tex]
To solve this, we simply substitute the values of a in the given expression
[tex]\sqrt{a^2} - 7 + |b|[/tex]
[tex]\sqrt{a^2} - 7 + |b| = \sqrt{2^2} - 7 + |-4|[/tex]
Express 2² as 4
[tex]\sqrt{a^2} - 7 + |b| = \sqrt{4} - 7 + |-4|[/tex]
Express square root of 4 as 2
[tex]\sqrt{a^2} - 7 + |b| = 2 - 7 + |-4|[/tex]
[tex]|-4| = 4[/tex]
So, we have
[tex]\sqrt{a^2} - 7 + |b| = 2 - 7 + 4[/tex]
[tex]\sqrt{a^2} - 7 + |b| = -1[/tex]
Hence, the result of the expression is -1
In the sequence 1. 2. 3. 4. 1.2.3.4... the numbers 1.2.3.4
repeat indefinitely. What is the sum of the first 150 terms?
A. 300
B. 77
C 37
D.3
=============================================
Explanation:
The sequence {1,2,3,4,1,2,3,4...} has "1,2,3,4" repeat forever. We can say that the cycle is 4 terms before it restarts the pattern again. Because of this 4-cycle pattern, we know that 150/4 = 37.5 = 37 full cycles happen. The leftover part is of length 150-37*4 = 2.
In short we have 37 full cycles of {1,2,3,4} happening. The last leftover bit has {1,2} only
In the subsquence {1,2,3,4} its sum is 1+2+3+4 = 10. Having 37 copies of {1,2,3,4} leads to a sum of 37*10 = 370 so far.
Then we add on the last bit 1+2 = 3 to get 370+3 = 373.
Therefore, the sum of the first 150 terms is 373. I think your teacher made a typo when listing out the answer choices. Please double check to make sure.

Let L be the line with parametric equations x=2+t, y=1-t, z=1+3t.Let v=(1,2,0).Find vectors w1 and w2 such that v= w1 + w2, and such that w1 is parallel to L and w2 is perpendicular to L.
Answer:
w1 = (-1/11, 1/11, -3/11)
w2 = (12/11, 21/11, 3/11)
Step-by-step explanation:
Direction ratio of w1 = Direction ratio of L (because parallel) = K+(1, -1, 3)
Let <a,b,c> be direction ratio of w2.
Then, <a,b,c>. <1,-1,3> = 0
a-b+3c = 0
v = w1 + w2
(1, 2, 0) = k(1, -1, 3) + (a, b, c)
a + k = 1
b - K = 2
c - 3k = 0
Solving 4 equations, a = 12/11, b= 21/11, c = 3/11, k=-1/11
So, w1 = -1/11(1, -1 ,3) = (-1/11, 1/11, -3/11)
w2 = (12/11, 21/11, 3/11)

Answer:
16 teachers.
Step-by-step explanation:

Hope this helped. Please give brainly if its the best!
Answer:
[tex] \huge \colorbox{blue}{16 students}[/tex]
Step-by-step explanation:
we are given the ratio of students and teachers:
[tex] \displaystyle \: \frac{21}{4} [/tex]
which means if the number of students is 21 then the number of teachers should be 4
to find how many teachers should go if students 84 we have to divide 84 by [tex]21/4[/tex] :
[tex] \displaystyle \: 84 \div \frac{21}{4} [/tex]
simplify division:
[tex] = \displaystyle \: 84 \times \frac{4}{21} [/tex]
simplify multiplication:
[tex] = \displaystyle \: \cancel{ 84} \: ^{4} \times \frac{4}{ \cancel{21}} \\ = 4 \times 4 \\ = 16 [/tex]

In a run-off election between two candidates, a total of 25,200 votes were cast. If 300 voters had switched
from the winner to the loser, the loser would have won by 200 votes. How many votes did each candidate
actually receive?
Step-by-step explanation:
yikes that's hard GG bro
Answer:
The winner received 12,800 votes and the loser received 12,400.
Step-by-step explanation:
Divided the votes in half, then took 100 votes from the winner, defined W, and added 100 to the loser, defined L to give the Loser a lead of 200. Then switch 300 votes from the losers number to the winner. You'll end up with 12,800 and 12,400 and you can check by switching 300 voters from winner (12,800) to loser (12,400) to make the loser win by 200 votes. 12,800 and 12,400 also add up to 25,200.

A line segment has the endpoints V(–3, –5) and W(16, –10). Find the coordinates of its midpoint M.
Answer:
(6.5, -7.5)
Step-by-step explanation:
Use the midpoint formula (x1 + x2) / 2 , (y1 + y2) / 2
Plug in the points:
(-3 + 16) / 2 , (-5 - 10) / 2
13/2 , -15/2
6.5, -7.5
So, the coordinates of midpoint M are (6.5, -7.5)
What is the vertex of f(x) = |x + 8| – 3?
Answer:
(-8,-3)
Step-by-step explanation:
This question is similar to the vertex form of a quadratic equation, so you can think of this equation like f(x) = (x-h)+k. Using this equation, you can determine the vertex (h,k) of |x+8|-3, which is (-8,-3).

Answer:
Quantitative data
Step-by-step explanation:
When we measure something, then we can quantify them. By also making a count, we are trying to quantify a particular entity.
Now in this case, we know that age is something we can quantify or measure. By nothing the difference between the year of birth and the present year, we can simply give the number of years or simply how
old a person is.
This clearly show that we have measured the count of that entity. This makes age an example of quantitative data

The Fairy Tale Spectacular is coming to town. Admission to the fair costs $32.50 and each ride costs $0.80. You have $50 to spend at the Fairy Tale Spectacular including admission. What is the maximum number of rides you can enjoy?
Answer:
21 rides
Step-by-step explanation:
let x = number of rides you can ride
32.50 + 0.80x [tex]\leq[/tex] 50
subtract 32.50 from both sides
0.8x [tex]\leq[/tex] 17.5
divide the left and right by 0.8
x [tex]\leq[/tex] 21.875
this means you can ride 21 times, because you can't ride a ride unless you can afford the whole cost
how to check; 32.50 + 0.8(21) is 49.30 and 80 cents more would go over your 50 dollar spending limit
