How to do number 13 and 14
Murrr4er [49]

From the information: v is 64 while c is 5

Differentiate the new equation h=-16t^{2} + 64t + 5 to get \frac{dh}{dt}= -32t + 64.

no 13). At maximum height this derivative equals zero so: -32t + 64 = 0;  -32t = -64; t=2.Hence ans is 2 secs

no 14). put t as 2 sec in the equation: h=-16t^{2} + 64t + 5.  This gives

h=-16( 2^{2}) + 64(2) + 5; h=-64+128+5=69. Hence h is 69ft

Paul wanted to bring his family to the Children’s Museum. There was an exhibit with carnival rides. The tickets for each ride we
Nostrana [21]

We want to define and solve a linear equation to model the given case.

The answers are:

a) x = number of tickets, y = total cost.

b) y = $1.35*x + $6.35

We know that:

The tickets for each ride were $1.35 per ticket.

Paul purchased 30 tickets

He spent a total of $46.85 (on tickets and admission)

The cost for the 30 tickets is:

30*$1.35 = $40.50

a) Now we can define two variables:

y = total cost

x = number of tickets

b) the linear equation would be:

y = $1.35*x + P

Where P is the price of admission.

And we know that the total cost for 30 tickets is $46.85, then we have:

$46.85 = $40.50 + P

$46.85 - $40.50 = P = $6.35

So the admission price is $6.35

This means that the linear equation is:

y = $1.35*x + $6.35

c) Brief explanation, we have the variable y that represents the total cost, it is equal to the admission price (which we found) plus $1.35 times the number of tickets bought (x).

Type your answer in the box.<br>Evaluate y3 – 2y (y – 5) + 13 when y = -3​
kap26 [50]

Answer:

-62

Step-by-step explanation:

y³ – 2y (y – 5) + 13

when y = -3

y³ – 2y (y – 5) + 13

=(-3)³ – 2(-3) [ (-3) – 5] + 13  (by PEDMAS, evaluate parentheses first)

=(-27) + (6) (-8) + 13   (next do multiplication)

=(-27) + (-48) + 13

= -27 - 48 + 13

= -62
