Select the correct answer. Which equation matches the function shown in the graph?
Answers
Answer:
B) [tex]y=sin(x+\frac{\pi}{2})[/tex]
Step-by-step explanation:
Technically, since the function starts at its maximum, you could say the function is [tex]y=cos(x)[/tex], but the answer choices all use sine instead. Therefore, we will have to use the cofunction identity [tex]cos(x)=sin(x+\frac{\pi}{2})[/tex] and we can see that the correct answer is B.
The equation matches the function provided in the graph is y = sin(x + π/2) option (B) is correct.
What is sin function?It is defined as the function which is sinusoidal in nature, and it has a domain of all real numbers and lies between the [a, a] where is a amplitude of the function.
It is given that:
A graph of a trigonometric function is given:
As we know,
y = sinx has a sinusoidal graph
Based on the graph we can apply a transformation to get the required function.
Applying transformation:
x → x + π/2
The sin function will shift left side by π/2 unit
The equation of the function becomes:
y = sin(x + π/2)
The equation of the function shown in the graph is y = sin(x + π/2)
Thus, the equation matches the function provided in the graph is y = sin(x + π/2) option (B) is correct.

Answer:
90
Step-by-step explanation:
Firstly, you divide 108 by 6, since 108 can't be divided by 5, and 108 divided by 6 gives you 18. Then you multiply 18 by 5, which gives you 90. Boom.

Answer:
14. ∠UVS = 63.6°
15. ∠TWU = 90°
16. ∠TUV = 116.4°
17. UW = √111 ≈ 10.5
18. SU = 2√111 ≈ 21.1
19. VT = 34
Step-by-step explanation:
The relevant relations for a rhombus are ...
diagonals bisect each other at right angles, dividing the figure into 4 congruent right trianglesthe diagonals bisect the vertex anglesadjacent vertex angles are supplementary__
14.Angle UVS is double the measure of angle UVW. 2×31.8° = 63.6°.
angle UVS = 63.6°
__
15.As we said above, the angles where the diagonals cross are right angles.
angle TWU = 90°
__
16.Angle TUV is supplementary to angle UVS. 180° -63.6° = 116.4°
angle TUV = 116.4°
__
17.UW is found using the Pythagorean theorem.
UW² +TW² = TU²
UW² = TU² -TW² = 20² -17² = 111
UW = √111 ≈ 10.536

Step-by-step explanation:
First, to find 20% of 440,620, you can multiply:
0.2 x 440,620 = 88,124
Then, to find the new weight of the ship, you can subtract the 20% that was just found (88,124) from the ship's original weight (440,620) to get:
440,620 - 88,124 = 352,496
Therefore, the ship's weight is now 352496.

Base angles are the same due to it being an isosceles triangle
Sum of angles in triangle = 180°
2x + 2x + (x - 15) = 1804x + x - 15 = 1805x - 15 = 1805x = 195x = 396.
Angle VZW and XZW are supplementary, meaning that they add up to 180°
3x + 17 + (x - 9) = 1803x + 17 + x - 9 = 1804x + 8 = 1804x = 184x = 46°7.
Sum of angles in a straight line add up to 180°
(2x - 4) + (3x + 5) + (2x + 11) = 1802x - 4 + 3x + 5 + 2x + 11 = 1807x + 12 = 1807x = 168x = 248.
All angles add up to 90°
x + (x + 4) + (3x - 9) = 90x + x + 4 + 3x - 9 = 905x - 5 = 905x = 95x = 19-Chetan K

The z score of a student who scores a 92 on the final exam is 2.67.
Z scoreZ score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ) / σ
where x is the raw score, μ is the mean and σ is the standard deviation
Given that σ = 6, μ = 76. For a raw score of 92:
z = (92 - 76) / 6 = 2.67

season. Together, these two players brought home 232 runs during the 2005 regular season. How many runs batted in did player A and player Beach account for?
CE
Player A had runs and player B had runs batted in for the 2005 regular season.
Answers
Answer:
ok so we trying to find out how many each batted so lets make this a system of equation
first we now that combined they are 232 so
a+b=232
then we now that b is 18 less then a so
a-18=b
the system of equation is
a+b=232
a-18=b
so we now what b is so we can just plug that in
a+a-18=232
2a-18=232
2a=250
a=125
then we can just plug this back in
125+b=232
b=107
a=125
b=107

Lincoln High School has 84 teachers. 12 of the teachers teach math. Of the 32 females teachers, 6 teach math.
What is the probability that a teacher is a woman or teaches math? Express your answer as both a fraction and a percetage.
Answers
Probabilities are used to determine the chances of events
The probability that a teacher is a woman or teaches math is 45.24%
How to determine the probabilityThe given parameters are:
Teachers = 84
Math teachers = 12
Female teachers = 32
Female math teachers = 6
The number of female or math teachers is:
Female or math = Math + Female - Female math
So, we have:
Female or math = 12 + 32 - 6
Female or math = 38
The probability that a teacher is a woman or teaches math is:
[tex]Pr = \frac{38}{84}[/tex]
Simplify
[tex]Pr = \frac{19}{42}[/tex]
Express as percentage
[tex]Pr = 45.24\%[/tex]

You just bought a new laptop and paid an initial payment of $150.00. You will make 12 payments of $69.50. How much will the computer cost if your state charges 6% sales tax on the total sale.
Answers
The computer will cost $924.96 after 6% tax.
Total cost of laptopThe initial payment of the laptop made = $150.00
The remaining balance that would be made = 12 × 69.50
=$834
Therefore total cost of laptop before tax = 834 + 150
= $984
But tax is 6% of total cost =
[tex] \frac{6}{100} \times 984[/tex]
[tex] \frac{5904}{100} [/tex]
= $59.04
Therefore, total cost of laptop after tax = 984 - 59.04
