Answer:
B.)8ft
Step-by-step explanation:
Set up a proportional to the roof slope:
2/5 = x/20
Cross multiply:
40/5 = 5x/5
x=8ft
Let
A (1,6)------> location <span>brianna's house on a map
B </span>(5,3)------> location Jordan's house on a map
we know that
One possible path from brianna's house to jordan's house it's a straight line ( <span>the shortest distance)</span>
using a graph tool
see the attached figure
find the distance points AB
d=√[(y2-y1)²+(x2-x1)²]-----> d=√[(3-6)²+(5-1)²]----> d=√[3²+4²]
d=√25----> d=25 units
the distance from brianna's house to jordan's house is 25 units
Answer: 0.375
Step-by-step explanation:
Let x be the event that at exactly 2 heads occurs
Let s be the sample space
Therefore;
n(s) = 8
n(x) = 3 (HHH, HHT, THH)
p(x) = n(x)/n(s)
p(x) = 3/8
p(x) = 0.375

Answer:
The equation of line with slope -7 passing through (5,9) in point-slope form is:
![y-9 = -7(x-5)](https://tex.z-dn.net/?f=y-9%20%3D%20-7%28x-5%29)
Step-by-step explanation:
Given
Slope of line = m = -7
Point = (5,9)
The point slope form of equation is obtained from a point and slope. It is given by the equation:
![y-y_1 = m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%20%3D%20m%28x-x_1%29)
We know that (x1,y1) = (5,9)
Putting the values we get
![y-9 = -7(x-5)](https://tex.z-dn.net/?f=y-9%20%3D%20-7%28x-5%29)
Hence,
The equation of line with slope -7 passing through (5,9) in point-slope form is:
![y-9 = -7(x-5)](https://tex.z-dn.net/?f=y-9%20%3D%20-7%28x-5%29)
