Answer:

5.5 units

Step-by-step explanation:

I'm not 100% sure if this is right, since it could be 5 or 6, but since there is a slight diagonality to it, i would say 5.5 units.

8. The talent show committee sold a total of 530 tickets in advance. Student

Alex Ar [27]

Answer:

Number of students tickets sold = x = 380 tickets

Number of adults tickets sold = y = 150 tickets

Step-by-step explanation:

Let

Number of students tickets sold = x

Number of adults tickets sold = y

x + y = 530 (1)

3x + 4y = 1740 (2)

From (1)

x = 530 - y

Substitute x = 530 - y into (2)

3x + 4y = 1740

3(530 - y) + 4y = 1740

1590 - 3y + 4y = 1740

- 3y + 4y = 1740 - 1590

y = 150

Substitute y = 150 into (1)

x + y = 530

x + 150 = 530

x = 530 - 150

x = 380

Number of students tickets sold = x = 380 tickets

Number of adults tickets sold = y = 150 tickets

Constructed Response Task

pav-90 [236]

The object takes 12 minutes to land on the ground.

Explanation:

Given that the equation for the object's height s at time t minutes after the launch is $s(t)=-16t^2+144t+576$

We need to determine the time that it takes for the object to land on the ground.

<u>Time taken:</u>

The time t of an object can be determined by substituting $s(t)=0$

Thus, we have,

$0=-16t^2+144t+576$

Switch sides,

Thus, we get,

$-16 t^{2}+144 t+576=0$

Let us solve the equation using the quadratic formula.

$t=\frac{-144 \pm \sqrt{144^{2}-4(-16) 576}}{2(-16)}$

$t=\frac{-144 \pm \sqrt{20736+36824}}{-32}$

$t=\frac{-144 \pm \sqrt{57600}}{-32}$

$t=\frac{-144 \pm 240}{-32}$

Thus, the values of t are $t=\frac{-144 + 240}{-32}$ and $t=\frac{-144 -240}{-32}$

Simplifying, we get,

$t=\frac{96}{-32}$ and $t=\frac{-384}{-32}$

$t=-3$ and $t=12$

Since, the value of t cannot be negative, then $t=12$

Thus, the object takes 12 minutes to land on the ground.
