Answer:

The initial velocity of the particle is

v' = -6 - 6.2 = -18 ft/s

at t = 5s, the velocity is v = -18 + 6.5 = 12 ft/s

the position is

x =  - 32  - 18 \times 5 +  \frac{1}{2}  \times 6 \times 5 {}^{2}  =  - 47 \: ft

the total distance traveled is

s =  | \frac{12 {}^{2}  - 18 {}^{2} }{2 \times 6} |  = 15 \: ft

Find the measure of angle 4
Morgarella [4.7K]

Answer:

38

Step-by-step explanation:

Notice that the first triangle is an isosceles triangle, meaning that the base angles are equivalent. Since one angle is 62, we know that the other is 62 as well, which makes 124. This means that angle 2 is 56 degrees. Since 2 and 3 are on the same 'line', they both add up to 180. If 2 is 56, then angle 3 is 124. So the three angles inside the triangle are 124, 18, and x. So, 124+18=142. 180-142= 38

Write the following equation in the general form ax by c = 0. y - x - 1 = 0
Elena-2011 [213]

If you would like to write y - x - 1 = 0 in the general form, you can do this using the following steps:

The general form of the equation is: ax + by + c = 0.

y - x - 1 = 0

-x - y - 1 = 0


The correct result would be <span>-x - y - 1 = 0</span>.
