The function g(x) = 3x-4 is a linear function. Therefore the inverse does exist (which is also linear)
Because we have an inverse, this means we can use the rule
Replace x with 13
The answer is choice D
Answer:
yes
Step-by-step explanation:
8² + 15² = 17²
64 + 225 = 289
289 = 289
Answer:
109.5; B
Step-by-step explanation:
From your identity,
CosA = adjacent/ hypothenus
A represent an arbitrary angle between the sides in question.
In the question above, A=64
Hypothenus is the longest side and adjacent is the side just below the angle .
In the above case,
Hypothenus= X
adjacent =48
This means;
Cos64 = 48 /X
X = 48 / cos64; [ from cross multiplication and diving through by cos64]
X = 48 /0.4383 [ cos64 in radian = 0.4383]
= 109.51
= 109.5 to the nearest tenth.
Note( do your calculation of angle in radian or else, you won't get the answer)
Answer:
x+3?
Step-by-step explanation:
honestly, there is not alot of information present here. so when a hear "a number" i think variable.... which would be set up as x+3
A right angles is 90 degrees, which means that 90-55= x
x = 35 degrees
