Answer:
0.4913376 km
Step-by-step explanation:
To solve the given question above, we have our conversion factor
1 foot = 0.000305 kilometre
1,612 feet = x km
Cross Multiply
xkm = 1612 × 0.000305
xkm = 0.4913376 km
Therefore, the height in Kilometers is 0.4913376km
Answer:
![y = \frac{1}{2}x + 8](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B2%7Dx%20%2B%208)
Step-by-step explanation:
The general slope-intercept equation is: y = mx + b.
In this equation, "m" is equal to the slope and "b" is equal to the y-intercept.
Since the slope is "1/2", then this is the "m" value.
Since the line passes the y-axis at "8" when x = 0, then "b" must be "8".
Therefore, the equation of the function in slope-intercept form is
.

Answer:
B. 8.6
Step-by-step explanation:
Given:
Draw a right angled triangle ABC as as shown below.
From the triangle
,
Calculate the number of units from A to C and from C to B, we get
AC = 7 units and BC = 5 units.
Now using Pythagorean Theorem,
![AB^{2}=BC^{2}+AC^{2}\\AB^{2}=(7)^{2}+(5)^{2}\\AB^{2}=49+25\\AB^{2}=74](https://tex.z-dn.net/?f=AB%5E%7B2%7D%3DBC%5E%7B2%7D%2BAC%5E%7B2%7D%5C%5CAB%5E%7B2%7D%3D%287%29%5E%7B2%7D%2B%285%29%5E%7B2%7D%5C%5CAB%5E%7B2%7D%3D49%2B25%5C%5CAB%5E%7B2%7D%3D74)
Taking square root on both sides, we get
![\sqrt{AB^{2}}=\sqrt{74}\\AB=8.6](https://tex.z-dn.net/?f=%5Csqrt%7BAB%5E%7B2%7D%7D%3D%5Csqrt%7B74%7D%5C%5CAB%3D8.6)
Therefore, the distance between points A and B rounded to the nearest tenth is 8.6 units.
