Answer:the sector is 280°
Step-by-step explanation:
Answer:
y > -14
Step-by-step explanation:
-5(y+2) < 60
-5y - 10 < 60 (Expand the term on the left)
-5y < 70 (Bring the numbers to the right)
y > -14 (Divide both sides by -5. Note that the inequality sign changes as we are dividing by a negative number)
Hence Answer is <u>y > -14</u>
So the question sets the problem with a bunch of different values given but it goes ahead does the work of putting them into an equation, since this equation they made gives us the position, when it is equal to zero the object has impacted the ground. Setting it to zero allows us to solve for t, the time at which it strikes the ground.
0 = -4.9t^2 + 19.6t + 58.8, because this is a quadratic, and a complicated one at that, we will use either a calculator, or the quadratic formula to solve for t.
No matter what way you solve it you will get two values, only the positive value applies because a negative value for time is illogical.
The answer is at t = 6 seconds
The formula for the area of a circle is A=πr². First, input 3.14 in place of pi, A=(3.14)r<span>². Then divide the diameter by 2 to get the radius and plug that in for r, A=(3.14)(12.2)</span>². Now solve, <span>A=467.3576. Finally, round your answer to the nearest hundredth, A</span>≈467.36
The answer is 15
if you do 8+7=15
i think it help
