<em><u>Question:</u></em>
Britney throws an object straight up into the air with an initial velocity of 27 ft/s from a platform that is 10 ft above the ground. Use the formula h(t)=−16t2+v0t+h0 , where v0 is the initial velocity and h0 is the initial height. How long will it take for the object to hit the ground?
1s
2s
3s
4s
<em><u>Answer:</u></em>
It takes 2 seconds for object to hit the ground
<em><u>Solution:</u></em>
<em><u>The given equation is:</u></em>
Initial velocity = 27 feet/sec
Therefore,
At the point the object hits the ground, h(t) = 0
Solve by quadratic formula,
Ignore, negative value
Thus, it takes 2 seconds for object to hit the ground
Answer:
114
Step-by-step explanation:
12% of 950 is 114, so since 12% more donuts are sold this week, we sold 114 more donuts this week compared to last week.
The answer would be .0333 hope this helped
Multiply by the opposite sign the denominator. In the denominator we have the difference of squares.
Here we are to find the values of x in which the function
f (x) = csc 5x is discontinuous. What this usually means is to find when the
value approaches infinity.
We know from trigonometric identities that csc is the
equivalent to 1 / sin, therefore the function in terms of sin is:
f(x) = 1 / sin 5x
We can see that the function becomes discontinuous when sin
5x = 0, that is a value divided by 0 is discontinuous or approaches infinity.
sin 5x is equal to zero when:
5x = 0 or π
So given k as an arbitrary integer
5x = k π
So k can be: k = 0, 1, 2
x = k π/ 5
