Deacon wants to order DVDs. Each DVD costs $12.95, and he must pay a shipping and handling fee of $4.95 for the entire order. De

Aneli [31]

Answer:

$12.95x + 4.95 \leq 75$

Step-by-step explanation:

Given

Represent number of DVDs with x

$Each\ DVD = \$12.95$

$Handling\ Fee = \$4.95$

$Budget = \$75$ (at most)

Required

Represent as an inequality

If $Each\ DVD = \$12.95$

x DVD would cost:

$x\ DVDs = 12.95 * x$

$x\ DVDs = 12.95x$

So, to make an order of x DVDs, Deacon will pay for

x DVDs and Handling Fee

So:

$Payments = 12.95x + 4.95$

Recall that his budget is at most $75

This implies that: $\leq 75$

So, the relationship between his payment and budget is:

$12.95x + 4.95 \leq 75$

A ball is thrown into the air. The height in feet of the ball can be modeled by the equation h = -16t2 + 20t + 6 where t is the

makkiz [27]

$f(t)=h=-16t^2+20t+6

$

a=-16, b=20, c =6

Δ= $b^2-4ac=20^2-4*(-16)*6=400+384=784$

$\sqrt{Δ}=\sqrt{784}=28$

max:

$p=-\frac{b}{2a}=-\frac{20}{-32}=\frac{20}{32}=\frac{5}{8}$

max heigh: $h=-16(\frac{5}{8})^2+20*\frac{5}{8}+6=-16\frac{25}{64}+\frac{100}{8}+6$

$h=-\frac{25}{4}+\frac{50}{4}+6=\frac{-25+50+24}{4}=\frac{49}{4}$

$h=\frac{49}{4}$ at $t=\frac{5}{8}s$

will fall down at t:

$t=\frac{-20-28}{-32}=\frac{-48}{-32}=\frac{3}{2}=1.5$

$t=1.5s$
