Answer:
B. 16.7
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relationship between the side adjacent to the angle and the hypotenuse involves the cosine function:
Cos = Adjacent/Hypotenuse
Filling in the numbers from your diagram gives ...
cos(50°) = x/26
Multiplying by 26 gives x.
x = 26·cos(50°)
x ≈ 16.7
Answer:
5(x-3)
Step-by-step explanation:
The word "SUM" means the answer to an "ADDITION".
"SUM" is always used with the word "AND" to indicate which numbers are being added.
The SUM of a number AND -3 is written as:
(
x
+
(
−
3
)
),
or (
x
-3
)
(where we have chosen the number to be x
.)
But we want FIVE of those sums; this means:
5 (
x
−
3
)
Answer:
they are both true
Step-by-step explanation:
they are both true because of proportionalities
5/8
5x2=10
8x2=16
therefore 5/8=10/16
the second one is also true because they want you to multiply y by 2
4x2=8
therefore
5/8=5/4x2
Answer:
Option 1.
Step-by-step explanation:
It's option 1.
You divide (b/a) by 2 then square it, then subtract this from both sides of the equation. It is the process of Completing the Square.
