Look at intersecting points of line on x- and y-axis.
The points would be: (8,0) & (0,4)
formula of slope = (y2-y1) / (x2-x1)
(4-0)/(0-8) = -4/8 = -1/2.
They created ratios so people could get information.
Answer: D. (8, 4)
Step-by-step explanation:
Answer:
linear
Step-by-step explanation:
The easiest (if not the only) way to solve this, is to check whether the slope at each point stays constant, or not. And in general, see how the rate rate of change evolves. In other words:
- 6.5 / 5 = 1.3
- 13 / 10 = 1.3
- 19.5 / 15 = 1.3
- 26 / 20 = 1.3
- 32.5 / 25 = 1.3
- 39 / 30 = 1.3
As you can see " in every step to the right, the function goes up by 1.3 " --> constant
So, the function is linear
Answer:
tan theta = 8/15
Step-by-step explanation:
Sin is equal to opposite over hypotenuse. So it means that the side opposite from theta is 8, and the hypotenuse is 17.
To find the value of the adjacent side from theta, use the Pythagorean Theorem.
a^2 + b^2 = c^2
8^2 + b^2 = 17^2
64 + b^2 = 289
Subtract 64.
b^2 = 225
Take the square root.
b = 15.
So that means:
the side opposite from theta is 8,
the side adjacent from theta is 15,
the hypotenuse is 17.
Now we take tan, opposite over adjacent, and use the values from the triangle.
tan = opposite / adjacent
tan = 8/15.
