Answer: 8.632
<u>Step-by-step explanation:</u>
First, you need to find the length of AE. Since ΔAEC is a right triangle, we can use:
Next, Use Heron's formula to find the Area of ΔADE.
Heron's formula is:
An explanatory variable is a type of independent variable. A response variable is a type of dependent variable. An explanatory variable is used to predict or explain differences in the response variable.
The first coordinate corresponds to independent variable and the second coordinate corresponds to dependent variable.
Since independent variable takes value 5 and dependent variable takes value 15, then the point (5,15) would be the point when plotted on a scatterplot.
Answer: correct choice D
Answer:
39
Step-by-step explanation:
We can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
15^2 + 36^2 = c^2
225+1296 = c^2
1521 = c^2
Take the square root of each side
39 = c
