Answer:
Explanation:
Compute the magnitude:
∣∣→a∣∣=√(−10)2+62+(−7)2
∣∣→a∣∣=√100+36+49
∣∣→a∣∣=√185
To obtain the unit vector of →a=(−10,6,−7), we divide each component by √185 but we should rationalize 1√185 to √185185:
ˆa=(−10√185185,6√185185,−7√185185)

▹ Answer
<em>Linear</em>
▹ Step-by-Step Explanation
As x increases by 4, y increases by 6.
13 + 4 = 17
17 + 4 = 21
21 + 4 = 25
0 + 6 = 6
6 + 6 = 12
12 + 6 = 18
Hope this helps!

Answer:
x=3.2 ft
Step-by-step explanation:
Just subtract them and take the square root.
(50x^2 + 250) -(40x^2 + 350) = x^2=10
x=3.2 ft
Answer:
4
Step-by-step explanation:
Given that:
Total pounds of apple = 7/2 pounds
Pounds of apple needed per batch of applesauce = 3/4 pounds
Number of batches of applesauce which can be made :
Total pounds of apple / pounds of apple needed per batch
7/2 ÷ 3/4
7/2 * 4/3
= 28/6
= 4 4/6
= 4 2/3
Hence, number of batches of applesauce which can be made is 4
Explanation
The sum of the three angles of a triangle has to be equal to 180 degrees.
So...
180-(75+50)
180-125
=55 degrees
X equals 55 degrees
