Answer:
B.) 22 square root of 2
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Recall a linear function, is a line on a graph made up of an infinite amount of points which satisfy the relationship. That means at x=3 there is a specific point on the line with an output. The value of a function at x=3 asks, what is the output y value for the input x value?
To find it, we locate 3 on the x-axis. We draw a vertical line directly to the line following the grid line. We mark the point on the line. We then draw a horizontal line directly to the y-axis following the grid line. The point we hit on the y-axis is the value of the function.
Here it is 4.
Answer:
question (1)
height of building = 308 ft
question (2)
cos 67.11 = 7/18
Explanation:
question (1)
Taking a look at the triangle, we can see that it is a right-angled triangle. This means that we can apply the special trigonometric identities.
The one we will use here is:
tan Θ = opposite / adjacent
where:
Θ = 72
the opposite side is the height of the building
the adjacent side = 100 ft
Substitute to get the height as follows:
tan(72) = height / 100
height = tan(72)*100 = 307.76 which is approximately 308 ft
question (2):
We are given that:
cos Θ = 7/18
therefore:
Θ = cos^-1(7/18)
Θ = 67.114
approximating to the nearest tenth, we would find that:
Θ = 67.11°

Answer:
See below
Step-by-step explanation:
we have f(x) = 8x + 29
essentially f(x) is a function and the number that goes in the blank is the input, whatever the input is you plug in to all values of x and evaluate to get the output
we are going to assume that we have to solve for f(4)
so we have f(4) = 8x + 29
because 4 is in the "input spot" we input a 4 for every x we see in the function
So we get f(4) = 8(4) + 29
we then simply evaluate
f(4) = 8(4) + 29
==> multiply 8 and 4
f(4) = 32 + 29
==> add 32 and 29
f(4) = 61
So if the input of f(x) was 4, the out put would be 61
