Answer:

A. More than $ 30

B. Less than $ 25,

C. More than Susain's

D. Less than

Step-by-step explanation:

∵ The much money owned by a person has less credit balance,

Suppose a person owes x dollars then his credit balance is -$ x,

Option A :

Suppose Maria's credit balance is x so his owned amount is -x,

Since, x < - 30

⇒ -x > 30

Hence, she owned more than $ 30,

Option B :

For susain, y is credit balance and -y is owned amount,

y > - 25

⇒ -y < 25

Hence, Susain owned less than $ 25,

Option C :

George credit balance = Suain credit balance - 5

If z represents the credit balance of george,

⇒ z < y

⇒ -z  > - y

Hence, George owned more than Susan,

Option D :

Let a represents the owed amount of Antonio,

a < -x - 15

-a > x + 15

Thus, the credit balance of Antonio is less than maria balance.

The daily advertising revenue (in dollars) for a local newspaper is given by the function R(t) = -18t2 + 720t – 103, where t is
erastovalidia [21]

Answer:

6647

Step-by-step explanation:

The computation of the advertising revenue for 15 years is shown below:

Given that

r(t) = -18t^2 + 720t - 103

where

t = number of years = 15

now put the value of t in the above equation

= -18(15)^2 + 720(15) - 103

= -4050 + 10,800 - 103

= 6647

A ball is thrown upward from ground level. Its height h, in feet, above the ground after t seconds is h-48t -16t^2.
Marat540 [252]

Answer:

36 feet.

Step-by-step explanation:

We have been given that a ball is thrown upward from ground level. Its height h, in feet, above the ground after t seconds is h(t)=-48t -16t^2. We are asked to find the maximum height of the ball.

We can see that our given equation is a downward opening parabola, so its maximum height will be the vertex of the parabola.

To find the maximum height of the ball, we need to find y-coordinate of vertex of parabola.

Let us find x-coordinate of parabola using formula x=-\frac{b}{2a}.

x=-\frac{-48}{2(-16)}

x=-\frac{48}{32}

x=-\frac{3}{2}

So, the x-coordinate of the parabola is -\frac{3}{2}. Now, we will substitute x=-\frac{3}{2} in our given equation to find y-coordinate of parabola.

h(t)=-48t -16t^2

h(-\frac{3}{2})=-48(-\frac{3}{2})-16(-\frac{3}{2})^2

h(-\frac{3}{2})=-24(-3)-16(\frac{9}{4})

h(-\frac{3}{2})=72-4*9

h(-\frac{3}{2})=72-36

h(-\frac{3}{2})=36

Therefore, the maximum height of the ball is 36 feet.
