Hi,
Answer is:
Irrational. Why?
Rational numbers are like 2:3 (Example) that is a Decimal.
Hope this helps!! Can you please mark Brainliest? Good Luck on your School assignment, and God Bless!
<span>h= (-16t^2 + 28t + 7) </span>
find the derivative to get time<span>
<span>
h' = (-32t + 28)
When the ball reaches its maximum height, its
vertical velocity (h’) will be 0 </span></span>
<span>
<span>
0 = -32t + 28 </span></span>
-32t=-28
<span><span>-28/-32 = </span>0.875
seconds </span><span>
<span>
The ball reaches its maximum height in 0.875
seconds after being thrown; plug and chug and:
h= (-16(0.875)^2 + 28(0.875) + 7) = 19.25 feet</span></span>
Max height = 19.25 feet, time = 0.88 seconds
Answer:
12.
Step-by-step explanation:
We have been given format of different numbers. We are asked to find the missing value for our given format.
Taking square root of 9 and 16 we will get,
Similarly, we can see that by taking the square root of all the on the left side of equation and adding them we get right side of equation.
Upon taking square root of 25 and 49 we will get,
Therefore, the missing number of our given sequence is 12.
Answer:
The slope is undefined.
Step-by-step explanation:
The line must pass through the points (10,-3) and (10,-8), meaning that it must be vertical. The slope of a line is undefined if the line is vertical.
Answer:The total probability that a random person has an accident in the given year is
.8×.01+.2×.04=0.016
The portion of that which is explained by careful drivers is .8×.01=.08. Thus the answer is
.8×.01.8×.01+.2×.04=.5
Thus it is equally likely that your accident victim was careful or careless.
Speaking informally, that's because, while it's four times more likely that a randomly selected driver is careful, it is one fourth as likely that a careful driver will have an accident, and the two
