Find the exponential equation for the given information. Pls help

Mathematics
1 answer:

Answer:

y = 12 (2.9)^{x}

Step-by-step explanation:

The standard form of the exponential function is

y = a (b)^{x}

Find a and b by substituting ordered pairs from the table into the equation

Using (0, 12 ), then

12 = ab^{0} ( b^{0} = 1 ), so

a = 12, then

y = 12 b^{x}

Using (1, 34.8 ) , then

34.8 = 12 b^{1} ( divide both sides by 12 )

b = 2.9

Thus exponential function is

y = 12 (2.9)^{x}

-5(x - 1) = – 7(x+3)<br> whats the answer
VARVARA [1.3K]

Answer:

x = -13

Step-by-step explanation:

-5(x - 1) = -7(x + 3)

Distribute on both sides.

-5x + 5 = -7x - 21

Add 7x to both sides.

2x + 5 = -21

Subtract 5 from both sides.

2x = -26

Divide both sides by 2.

x = -13

It takes 3 tractors 2 hours to plow a square field whose side is 600 meters. find the number of hours it would take 5 tractors t
NeTakaya

Answer:

5 tractors can plow a square field of side length 1,000 meters in 3.33 hours (3 hours 20 minutes)

Step-by-step explanation:

Let's find out how much each tractor can plow each hour.

\frac{600^{2} }{3*2}=60,000m^{2} per tractor per hour

1,000^{2}=1,000,000m^{2} is the area of the field of side length 1,000 meters

5 tractors can plow 300,000m^{2} per hour.

\frac{1,000,000}{300,000}=3.33 hours
