Answer:
u = 1/6
Step-by-step explanation:
<u>1</u> (12u - 2 )= 0
3
3×<u>1</u> (12u-2) =0×3
3
12u -2 =0
<u>12u</u> = <u>2</u>
12 12
u = <u>1</u>

The answer you are looking for is C. 8.
To find this you could Pythagorean Theorem. The base or bottom of the triangle would be 7, and the "leg" of the triangle would be 3. In this instance, we will call 3 "a" and 7 "b". We use these two numbers to find the missing value, which is "c" or the hypotenuse.
The formula for Pythagorean Theorem is "a^2 + b^2 = c^2". Then we follow these steps.
- Fill in the known values. 3^2 + 7^2 = c^2
- Simplify the squared numbers. 9 + 49 = c^2
- Add the numbers together. 58 = c^2
- Square root both sides. √58 = c.
- Round up to the nearest whole mile. 7.615 = c; c = 8.
Here's a picture to show how I did this. I hope this helps!
First, break up 45 into 40 and 5 then multipy 8(40) which equals 320 and multipy 8(5) which equals 40. Thrn add 320+40 to get the product 360.
Hope this helped
8x45
8(40)+8(5)
320+40
360
Answer: see below
Step-by-step explanation: Initial velocity = terminal velocity. At the top of travel, the velocity is 0 as the ball is motionless. Then it travels 3 seconds (due to gravity). Grav is 9.8m/sec squared. So 1st second = 9.8m. 2nd second is 2x9.8m. 3rd second is 3x9.8m = 29.4 m/sec.
The answer should be 4. (2, 1)
