Answer:

The correct answer is B

Step-by-step explanation:

Let's understand the graph.

A line is drawn starting in 4.5 and involving all numbers greater than 4.5.

But notice that in the starting point the line is drawn with an open circle, this means that the line does not consider 4.5 as part of its domain, this means that 'k' values are greater than 4.5.

Values greater than 4.5 are represented as >4.5, then:

k>4.5, which is option B, because:

k>9/2 = k>4.5

Note: Option A (k≥4.5) means that the line involves 4.5 as part of its domain, which is false as mentioned before.

a ball is shot straight upward. with it's height, in feet, after t seconds given by the function f(t)=-16t^2+192t. Find the aver

jekas [21]

ANSWER

$80 {ms}^{ - 1}$

EXPLANATION

The average velocity of the ball is the rateof displacement over the total time.

The height of the ball, in feet, after t seconds is given by the function:

$f(t)=-16t^2+192t$

At time t=1, the height of the ball is

$f(1)=-16(1)^2+192(1)$

$f(1)=-16+192 = 176ft$

At time t=6, the height of the ball is

$f(6)=-16(6)^2+192(6)$

$f(6)=-16(36)+192(6)$

$f(6)=-576+1152 = 576$

The average velocity

$= \frac{f(6) - f(1)}{6 - 1}$

$= \frac{576- 176}{6 - 1}$

$= \frac{400}{5}$

$= 80 {ms}^{ - 1}$

Please help need to know the answer to this supposedly is 9 + (9x36) 333 but I don’t get it

Ahat [919]

Answer:

459

Step-by-step explanation:

First line:

clock showing 9 o'clock + clock showing 9 o'clock + clock showing 3 o'clock = 9 + 9 + 3 = 21

Second line:

The calculators look exactly the same.

3 * calculators = 30

1 calculator = 10

Third line:

1 bulb + 1 bulb - 1 bulb = 15

Since 1 bulb - 1 bulb = 0, we have 1 bulb + 0 = 15, or

1 bulb = 15

Last line:

Clock showing 9 o'clock = 9

Calculator = 10

3 bulbs = 3 * 15 = 45

Total = 9 + 10 * 45 = 9 + 450 = 459

Rolls are being prepared to go to grocery stores. Divide 72 rolls into 2 groups so the ratio is 3 to 5.

tekilochka [14]

To do this, nice it to add 3 and 5, then divide 72 by the result of sum 3 and 5. Finally multiply it by 3 and by 5 to get the result.
Lets do this
3+5=8
72:8=9 - number of rolls in 1 "unit"
9*3=27 - first group
9*5=45 - second group
