Answer:I think you do 23.8-90
Step-by-step explanation:
To solve this problem, we will need the standard kinematics equation
where
v0=initial velocity (positive upwards) m/s
t=time in seconds
a=acceleration due to gravity (positive upwards) = -9.81 m/ ²
Substituting values,
distance = 0 (when it falls back on earth)
v0=42 m/s
a=-9.81 (negative means towards earth, downwards)
factor and solve
=>
t=0 (beginning of launch), or
42-(1/2)*9.81t=0 => t=2*42/9.81=8.563 s.
Time to return = 8.6 seconds (to the nearest tenth of a second)
Basically, we are to find the area of the television screen. Because a TV is rectangular in form, the formula for the area is written below:
A = L×W
The given dimensions are 64 inches in length and 52 inches in width. But that includes the edges. To compute for the screen area only, we subtract 4 inches (2 inches on both sides) to each dimension.
A = (64 - 2)(52 - 2)
A = 3,100 square inches
Answer:
69,420

#6 asks for a double angle.
Add an extra item to step 3: Draw an arc from vertex through the line
--> then draw another arc from B' to the other side of your line (away from the dot) and label that intersection as B''. Use the measure of the vertex to B'' for the remaining steps.
<em>If you need step-by-step images, you will need to post #6 separately as I can only upload 5 images per question.</em>
