Answer:
19. D
20. A
Step-by-step explanation:
19. Tan= opp/adj
20. Sin= opp/hyp
Answer:
y=9
Step-by-step explanation:
First we need to solve al addition and subtraction by performing the inverse operation. In this case, we need to add to reverse the subtraction
y/3 -4= -1
y/3= 3
Now we solve all multiplication and division again using the inverse operation, which in this case is multiplication, because the variable is being divided.
y/3=3
y=9
Thus we get that the value for y is 9.
Hope this helped!
Btw you're very pretty! <3
You would use the formula for the specific term you wish to find;
The formula is:

a = starting value of the sequence
d = the common difference (i.e. the difference between any two consecutive terms of the sequence)
n = the value corresponding to the position of the desired term in the sequence (i.e. 1 is the first term, 2 is the second, etc.)
Un = the actual vaue of the the term
For example, if we have the arithmetic sequence:
2, 6, 10, 14, ...
And let's say we want to find the 62nd term;
Then:
a = 2
d = 4
(i.e. 6 - 2 = 4, 10 - 6 = 4, 14 - 10 = 4;
You should always get the same number no matter which two terms you find the difference between so long as they are both
consecutive [next to each other], otherwise you are not dealing with an arithmetic sequence)
n = 62
And so:
Answer:
PR=22
Step-by-step explanation:
3x+6x+4=14x-6
9x+4=14x-6
10=5x
x=2
Plug in
3(2)
6
6(2)+4
12+4
16
16+6
22
So the bottom should equal 22
14(2)-6
28-6
22
