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

torisob [31]

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>

What is the domain of the relation?

TiliK225 [7]

Answer:

The domain of the relation is $[(5,16,18,21]$

Step-by-step explanation:

we have

$[(15,65),(21,70),(18,73),(16,62)]$

Remember that

The domain of the relation are the values of x

The range of the relation are the values of y

therefore

The domain is

$[(5,21,18,16]$

order them from lowest to highest -------> $[(5,16,18,21]$

The range is

$[65,70,73,62]$

order them from lowest to highest -------> $[62,65,70,73]$

Use function notation to represent the area of a circle whose circumference is 103 cm

Nataly_w [17]

Circumference of the circle $=103$ cm

i.e., $C = 2 \pi r = 103$

i.e., $r = \frac{103}{2 \pi}$

Area of the circle is given by

$A = \pi r^2$

$A = \pi (\frac{103}{2 \pi})^2$

$A = \pi (\frac{10609}{4 \pi^2})$

$A =\frac{10609}{4 \pi}$

Therefore, the area of the circle is: $A =\frac{10609}{4 \pi}$ $cm^2$

The following figures are not drawn to scale but AB and CD (if present) are straight lines. Find x

miss Akunina [59]

Answer:

x=45°

Step-by-step explanation:

A straight line is 180°. Since we have a 90° angle, and CD is a straight line, 90/2=45

45° is the answer.

Hope this explanation is understandable!

Hope this helps!

If not, I am sorry.
