The pair of equations below is a result of constructing the altitude, h, in Triangle ABC is A; sin C = h/a and sin A = h/c.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
We know:
[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}[/tex]
So from the attached figure;
sin C = h/a
sin A = h/c
These expressions have an h term in common. We can combine them if we can find forms of the expressions in terms;
h = a (sin C)
h = c (sin A)
Thus, option A is correct pair.

Answer:
C
Step-by-step explanation:
1. P(E)>P(D) (Event E is more likely to occur, therefore it has a greater probability)
2. P(E)>0.5 (The probability of event D is given as 0.5, so rewrite P(D) in the inequality)
3. 0.5 is equal to 0.5 and 0.1 is less than 0.5, so you can rule out options A and D
4. This leaves us with options 1.5 and 0.9, but it is impossible to have a probability that is greater than equal to one, so you can immediately rule out B
5. After this elimination process, the only remaining answer is C) P(E)=0.9

Answers
Answer:
(n - 8n)(m+8n)
Step-by-step explanation:
x² - y² = (x - y)(x + y)
In this situation, the "x" = m and the "y" = 8n
So,
m² - 64n² = (n - 8n)(m+8n)
Answer:
(m - 8n)(m + 8n)
Step-by-step explanation:
m² - 64n² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
m² - 64n²
= m² - (8n)²
= (m - 8n)(m + 8n)
The two dot plots show the number of miles ran by 14 students at the beginning and at the end of the school year compare each measure of the two dot plots
Answers
The two dot plots are missing, so i have attached it.
Answer:
The mean at the beginning of the school year was 9.5 miles and the mean at the end of the school year was 10.2 miles
Step-by-step explanation:
From the attached image, we are told to compare the means for each plot to the nearest tenth.
Mean = Σx/n
Now, from the image, total number of miles run by the 14 students at the beginning of the school year is;
(1 × 7) + (2 × 8) + (4 × 9) + (4 × 10) + (2 × 11) + (1 × 12) = 133
Mean of miles run at the beginning of the school year = 133/14 = 9.5 miles
Again, from the table, total miles run at the end of the school year = (2 × 8) + (2 × 9) + (4 × 10) + (3 × 11) + (3 × 12) = 143
Mean of miles run at the end of the school year = 143/14 = 10.2 miles
Thus;
The mean at the beginning of the school year was 9.5 miles and the mean at the end of the school year was 10.2 miles

casey has the faster rate
Step-by-step explanation:
first multiply jessicas race distance and time by 2
30 * 2
= 60
5 * 2
= 10
we did that so both jessicas time and caseys time was the same, making it easier to solve ( also by this point we already know who has the faster rate )
now we are going to divide both of their times and distances by 5
casey
10/5
= 2
45/5
= 9
jessica
10/5
= 2
60/5
12
the step is to divide their times/distances once again but this time by 2
casey
2/1
= 1
9/2
= 4.5
jessica
2/1
= 1
12/2
= 6
and our answer is 4.5 or casey !
4.5 > 6

Answers
Answer:
2,616.67cm³
Step-by-step explanation:
Find the diagram attached
volume of the cone = πr²h/3
r is the radius = 10cm
h is the height = 25cm
Substitute
V = 3.14(10)²*25/3
V = 314*25/3
V = 7850/3
V = 2,616.67cm³
Hence the volume of the cone to the nearest hundredth is 2,616.67cm³
