Number 24 only A B C and D

stepan [7]

Answer:

a) V = 288 - h

b) (0,288)(1,276)(2,264)(3,252)(4,240)

c) graph the above point

d) Volume decreases as height increases

Step-by-step explanation:

Step 1 :

The given equation is V = 12(24-h)

Using the distributive property we have

V= 12*24 - 12 * h = 288-h

The ordered pairs (h,V) can be obtained by giving different values for h and computing the corresponding V values

When h = 0 ,V= 288 -0= 288

When h = 1 ,V= 288 -12*1= 276

When h = 2 ,V= 288 -12*2= 264

When h = 3 ,V= 288 -12*3= 252

When h = 4 ,V= 288 -12*4= 240

Hence the ordered pairs are (0,288)(1,276)(2,264)(3,252)(4,240)

Step 3 :

The above points can be graphed using the values of h in the x axis and the values of V in the y axis

Step 4:

The above equation shows that the value of the volume V decreases as the value of h increases and becomes negative for values of h >24

What number should be added to both sides to complete the square? x^2 + 8x = 4

son4ous [18]

Answer:

Step-by-step explanation:

x² + 8x = 4 ⇔ x² + 8x + 16 = 4 + 16 ⇔ x² + 2×4x + 4² = 20 ⇔ (x + 4)² = (2√5)²

Remark : (2√5)² = 20

will mark brain edgiunuity ASAP Eight hundred tickets are sold for a play. Thirty-five percent of those tickets were sold in adv

Natalka [10]

Answer:

$Equation = \frac{35}{100} * 800$

Step-by-step explanation:

<em>The options are not well presented; however, the solution is as follows</em>

Given

Number of tickets = 800

Advanced = 35%

Required

Equation to find tickets sold in advance

To get the number of tickets sold in advance, we simply multiply the percentage ticket by the total tickets;

The equation becomes

$Equation = 35\% * 800$

Convert percentage to decimal

$Equation = \frac{35}{100} * 800$

Solving further to get the actual tickets sold

$Advance = 35 * 8$

$Advance = 280$
