Leyla drops a penny from a height of 150 m. How long will it take the penny to hit the ground? Use the formula h(t)=−4.9t^2+vt+h

, where v is the initial velocity and h is the initial height. Round to the nearest tenth of a second.

To determine the time it  takes for the penny to reach the ground, we use the relation of height and time given above. We do  as follows:
<span>
0 =−4.9t^2+(0)t+150
t = sqrt( 150/4.9)
t = 5.53 s

Hope this answers the question. Have a nice day.</span>

Round 4.645 to the nearest whole number! Please explain step by step to get marked
Gemiola [76]

Step-by-step explanation:

to round 4.645 to the nearest whole number consider the tenths’ value of 4.645, which is 6 and equal or more than 5. Therefore, we have to round up: the whole number part of 4.645, 4, increases by 1 to 5, and the decimal point and all digits (.645) are removed.

4.645 rounded to the nearest whole number = 5

Write the inequality:<br><br> Two less than twice a number is less than a half.
Art [367]

Answer:

2x-2<1/2

Step-by-step explanation:

when the problem says "two less than" it means we are subtracting 2 from something, in this case, that something is "twice a number" as the problem states. So we would write 2x where x is a variable that represents any number so we have 2x-2<1/2.

How do you write range on a graph?
Ratling [72]

The range of a function is the set of all possible outputs.

When the quadratic functions are in standard form, they generally look like this:

f(x) = ax^{2}  + bx + c

If a is positive, the function opens up; if it’s negative, the function opens down. In this form, the y-coordinate of the vertex is found by evaluating f(−\frac{b}{2a}). For example, consider this function:

f(x) = -2x^{2} + 8x -3\\

So we’re gonna do: −b/2a=−8/2(−2)=−8/−4=2

Then, we plug this in:

f(2) = -2(2)^{2} +8(2) -3 = 5

a is negative, so the range is all real numbers less than or equal to 5.
