Answer:

They will be picked up at 2 \frac{1}{4} yards above sea level

Step-by-step explanation:

Let us consider sea level as reference and positions above sea level as positive and below sea level as negative.

With respect to this reference,

the position of top most point is +17 \frac{3}{4} yards

and the position of lower most point is -13 \frac{1}{4} yards

⇒ The position of midpoint is \frac{+17 \frac{3}{4} - 13 \frac{1}{4}}{2}

                                              = +2 \frac{1}{4}

∴ <u>They will be picked up at 2 \frac{1}{4} yards above sea level</u>

nikklg [1K]

Answer:

30

Step-by-step explanation:

Sum of ages= 40

Let the sons age be x

Fathers age = 3 times x or ,3x

So 3x+x=40

4x= 40

x= 40/4

= 10

Therefore the fathers age = 3x

= 3*10

= 30

A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function h(t)=72t-16t^2. What is the
irakobra [83]

Answer:

The maximum height that the ball will reach is 81 ft

Step-by-step explanation:

Note that the tray of the ball is given by the equation of a parabola of negative main coefficient. Then, the maximum value for a parabola is at its vertex.

For an equation of the form

at ^ 2 + bt + c

So

the t coordinate of the vertice is:

t =-\frac{b}{2a}

In this case the equation is:

h(t)=72t-16t^2

So

a=-16\\b=72\\c=0

Therefore

t =-\frac{72}{2(-16)}

t=2.25\ s

Finally the maximum height that the ball will reach is

h(2.25)=72(2.25)-16(2.25)^2

h=81\ ft

A monitor that regularly costs $100 is on sale for 15% off. The salesperson offers you 20% off the sale price. What percent of t
nata0808 [166]
100*.85 (15% off) is $85.
$85 * .80 (20% off) is $68.
$100 - $68 is 32. So it would be 32% off of the original price.
