Answer:
Step-by-step explanation:
We do not have enough information for slope intercept form. But we can use the point-slope formula to find the information. The formula is 
where we substitute a point (x,y) for 
.
We have m=3/4 and (4, 1). We input m and 
.
We now simplify the parenthesis and solve for y.
We convert -4 into a fraction with 1 as the denominator.
We add 1 to both sides to isolate y,
This is slope intercept form. The line as slope 3/4 and y-intercept (0,2) or b=2.
Answer:
Yes no yes yes
Step-by-step explanation:
One example is if you wanted to measure the height of a tall building. You'll need to measure the distance from where you're standing to the base of the building. You'll also need the angle of elevation. To get the angle of elevation, start by looking completely horizontal, then tilt upward until your eyeline reaches the top of the building. Once you have those two things (the side and angle) you can use the tangent ratio to find the height. This is because
tan(angle) = opposite/adjacent
where in this case
angle = angle of elevation
opposite = height of building
adjacent = distance from your position to the base of the building
It takes a bit of algebra, but the opposite side can be solved for. You'll most likely need a calculator to compute the tangent ratio.
Answer: The coefficient of determination = 0.6291
Step-by-step explanation:
Given: Total variation is 24.488, the explained variation is 15.405, and the unexplained variation is 9.083.
The coefficient of determination is computed as:
Substituting given values, we get
Therefore, the coefficient of determination = 0.6291
Answer:
D is the answer
Step-by-step explanation:
If every year the value decreases by $1,500 that variable will change, but the price he bought the car at will not. That is why the x variable(standing for years) would go into the 1,500. And if each year the value decreases the answer would be D
