Tangent is the ratio opposite/adjacent
tan(angle) = opposite/adjacent
tan(x) = 8/5
tan(x) = 1.6
x = arctan(1.6)
x = 57.9946
x = 58 degrees which is the answer
The answer is approximate to the nearest whole number. Make sure your calculator is in degree mode.
Answer:
slope of AB = 0
Step-by-step explanation:
The slope of the x- axis OX = 0
Since AB is parallel to the x- axis and parallel lines have equal slopes, then
slope of AB = 0
Answer:
y = -3x + 4
Step-by-step explanation:
sorry im late
but all you have to do is isolate the y
so to do that we have to get rid of the 3x
3x + y = 4
in order to do that we have to subtract 3x from both sides of the equal sign since it is positive and being added to the y
3x + y = 4
-3x -3x
y = -3x + 4
and now y is isolated
The answer would be D. Because it moved over the x axis and it is reflecting.
Answer:
The quick answer I think will help you in the long run is that (f*g)(x) is just another way of saying f(x)*g(x). If that is enough, then ignore the rest of my response. Otherwise, keep reading.
For this problem
Step-by-step explanation:(f*g)(x) = f(x)*g(x)
You are given f(x) = 3x + 2 and g(x) = x^2 + 1. Simply substitute these expressions as follows:
f(x)*g(x) = (3x + 2)*(x^2 + 1)
Notice how I put each expression in parentheses. This practice will help immensely when dealing with more complicated expressions like this. Next, we simplify:
(3x + 2)*(x^2 + 1) = (3x)(x^2) + (3x)(1) + (2)(x^2) + (2)(1) <-- the foil method
= 3x^3 + 3x + 2x^2 + 2 <-- simplify each term
= 3x^3 + 2x^2 + 3x + 2 <-- reorganize and group like terms
hope this helped!
