Answer:
(1.2. - 4.7)
Step-by-step explanation:
On a coordinate plane, a line is drawn from point A to point B. Point A is at (7,-2) and point B is at (-8,-9).
Now, it is asked the x- and y-coordinates of point C, which partitions the directed line segment from A to B into the ratio 5:8.
So, the coordinates of point C are
![[\frac{5 \times (- 8) + 8 \times 7}{5 + 8}, \frac{5 \times (- 9) + 8 \times (- 2)}{5 + 8}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B5%20%5Ctimes%20%28-%208%29%20%2B%208%20%5Ctimes%207%7D%7B5%20%2B%208%7D%2C%20%5Cfrac%7B5%20%5Ctimes%20%28-%209%29%20%2B%208%20%5Ctimes%20%28-%202%29%7D%7B5%20%2B%208%7D%5D)
= ![[\frac{16}{13}, \frac{-61}{13}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B16%7D%7B13%7D%2C%20%5Cfrac%7B-61%7D%7B13%7D%5D)
= (1.2. - 4.7) (Answer)
{Round to the nearest tenth}
Answer:
- 
Step-by-step explanation:
Given
f(x) = 
- 
Evaluate f(19) by substituting x = 19 into f(x)
f(19) = 
- 
= 
- 
= 
- 4
= - 
= -
Answer: The standard deviation formula may look confusing, but it will make sense after we break it down. ...
Step 1: Find the mean.
Step 2: For each data point, find the square of its distance to the mean.
Step 3: Sum the values from Step 2.
Step 4: Divide by the number of data points.
Step 5: Take the square root.
Step-by-step explanation:
If you use the formula V=bh you can find the volume of a tranangular prism.
To find the area of the triangle you have to use the formula A=1/2bh
A=1/2(14)(20)=140ft2= Base of the triangle
V=bh V=140x30
V=4200ft2
