Answer:

-3, 7, 8

Step-by-step explanation:

You can fill in the boxes from the table values as shown in the attachment.

The leading coefficient is negative because the parabola opens downward. The value of it is the change in y-value as x changes by 1 unit either side of the vertex.

The vertex is identified by the fact that the y-values are symmetrical either side of the vertex.

Kirk used 10.2 centimeters of tape to wrap 3 presents. How many presents did Kirk wrap if he used 23.8 centimeters of tape?

insens350 [35]

Answer:

Kirk wrapped 7 presents with those 23.8 cm of tape.

Step-by-step explanation:

Figure out the unit rate:

10.2 cm tape

-------------------

3 presents

-----------------------

10.2 cm tape

Multiplying this by 23.8 cm results in the number of presents Kirk wrapped with that much tape:

(3 presents)(23.8 cm tape

--------------------------------------- = 7 presents

10.2 cm tape

Kirk wrapped 7 presents with those 23.8 cm of tape.

PLEASE ANSWER FAST What is the average of the following two numbers? 5.67 x 10^-21 and 7.24 x 10^-19

adell [148]

Answer: The average of two numbers is $3.64835\times 10^{-19}$ .

Explanation:

The first term is,

$5.67\times10^{-21}$

The second term is,

$7.24\times10^{-19}$

Average formula is,

$Average=\frac{\text{Sum of observations}}{\text{Number of observations}}$

$Average=\frac{5.67\times10^{-21}+7.24\times10^{-19}}{2}$

$Average=\frac{5.67\times 10^{-2}\times10^{-19}+7.24\times10^{-19}}{2}$

$Average=\frac{0.0567\times10^{-19}+7.24\times10^{-19}}{2}$

$Average=\frac{(0.0567+7.24)\times10^{-19}}{2}$

$Average=\frac{(7.2967)\times10^{-19}}{2}$

$Average=3.64835\times10^{-19}$

Therefore, the average of two numbers is $3.64835\times 10^{-19}$ .
