Height. Shadow
2.1 m. 5.3 m
X m. 34 m
X=2.1•34/5.3
X=71.4/5.3
X=13.47 m
X~13.5 m
OK
The first one would be
8.34625
The second one would be
22.89104

She is wrong. The way we know this is by this. If you are going 70 mph for 30 miles than you have to spilt the mph sign in half so 35 miles in 30 minutes.The you subtract 4 from each getting 31 miles in 26 minuets. Therefore Lethna is wrong.

Option C:
is the right answer
Step-by-step explanation:
Given points are:
(x1,y1) = (-1,2)
(x2,y2) = (3,4)
First of all, the slope has to be found
![m =\frac{y_2-y_1}{x_2-x_1}\\=\frac{4-2}{3+1}\\= \frac{2}{4}\\=\frac{1}{2}](https://tex.z-dn.net/?f=m%20%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5C%3D%5Cfrac%7B4-2%7D%7B3%2B1%7D%5C%5C%3D%20%5Cfrac%7B2%7D%7B4%7D%5C%5C%3D%5Cfrac%7B1%7D%7B2%7D)
The slope-intercept form of line is:
![y = mx+b](https://tex.z-dn.net/?f=y%20%3D%20mx%2Bb)
Putting the value of m
![y = \frac{1}{2}x+b](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B2%7Dx%2Bb)
Putting (3,4) in equation
![4 = \frac{1}{2}(3) +b\\4 = \frac{3}{2} +b\\b = 4 - \frac{3}{2}\\= \frac{8-3}{2}\\=\frac{5}{2}](https://tex.z-dn.net/?f=4%20%3D%20%5Cfrac%7B1%7D%7B2%7D%283%29%20%2Bb%5C%5C4%20%3D%20%5Cfrac%7B3%7D%7B2%7D%20%2Bb%5C%5Cb%20%3D%204%20-%20%5Cfrac%7B3%7D%7B2%7D%5C%5C%3D%20%5Cfrac%7B8-3%7D%7B2%7D%5C%5C%3D%5Cfrac%7B5%7D%7B2%7D)
Putting the value of b
![y = \frac{1}{2}x+\frac{5}{2}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B2%7Dx%2B%5Cfrac%7B5%7D%7B2%7D)
Hence,
Option C:
is the right answer
