A 2-column table has 5 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2. The second column is la
nikdorinn [45]

Answer:

f(x) = 3(2)^x

Step-by-step explanation:

The Table is:

<u>x</u>    <u>f(x)</u>

-2   3/4

-1    3/2

0    3

1     6

2    12

The exponential funtion has the next form:

f(x) = a(b)^x

At x = 0, f(x) = a. Then, a = 3

Isolating b from the equation:

f(x)/a = b^x

ln(f(x)/a) = x*ln(b)

[ln(f(x)/a)]/x = ln(b)

At x = 1, f(x) = 6. Then:

[ln(6/3)]/1 = ln(b)

ln(2) = ln(b)

2 = b

Therefore, the function is f(x) = 3(2)^x

A right pyramid with a square base has a base edge length of 12 meters and slant height of 6StartRoot 2 EndRoot meters. The apot
Jet001 [13]

Answer:

Volume of the right pyramid = 288 m²

Step-by-step explanation:

Volume of the pyramid = \frac{1}{3}\times {\text{Area of the rectangular base}\times height(h)

From the ΔAOB,

By Pythagoras theorem,

AB² = AO² + OB²

(6√2)² = AO² + (6)²

72 = AO² + 36

AO = √(36) = 6 m

Since base of the pyramid is a square so area of the base = (Length × Width) = (side)²

Now volume of the pyramid = \frac{1}{3}[(Length)(width)]\times height

                                               = \frac{1}{3}(12\times 12)\times 6

                                               = 288 m²

Therefore, volume of the right pyramid is 288 m².

Aarti bought a square shaped table cloth for her home the side of the table cloth measures 2 1/3m what is the area of the table
PSYCHO15rus [73]

Answer:

Area of table cloth =  49/9 m² or 5.44 m²

Step-by-step explanation:

Given:

Side of table cloth  = 2\frac{1}{3}m = 7/3 m

Shape of cloth is square

Find:

Area of table cloth

Computation:

Area of square = side²

So,

Area of table cloth = side²

Area of table cloth = (7/3)²

Area of table cloth =  49/9 m² or 5.44 m²

Kimani works for the city and is reimbursed for his mileage when traveling for work. In order to submit his reimbursement form,
IceJOKER [234]
The mileage from the Supermarket to the Library may be calculated using Pythagorean Theorem.

The coordinates of the Library are (7,10) and the coordinates of the Supermarket are (3,7).

So, the distance requested is √ [ (7-3)^2 + (10 - 7)^2 = √[ 4^2 + 3^2 = √ [16 + 9] =

= √25 = 5

So, he runs 5 miles.

And the reimbursement will be $0.50 / mile * 5 mile = $ 2.50.

Answer: option B) $ 2.50
