You are given the dollar value of a product in 2015 and the rate at which the value of the product is expected to change during

Charra [1.4K]

Answer:

V = $3.50t + $90.5....

Step-by-step explanation:

V(t) is a function of t that expresses the value in year 2000+t.

We know that the increase is $3.50 times t.

So,

V(t) = $3.50t + c

where c is the constant.

V(15) = $3.50 (15) + c = $143 [t=15 as mentioned in the question]

and therefore

c = $143 - $3.50 (15)

c= $143 - $52.50

c= $90.5

Now we got the value of c. We can write the equation as

V = $3.50t + $90.5....

A farmer has a bale of hay with mass of 36 kilograms. How many milligrams of hay are in the bale?

Ilia_Sergeevich [38]

KILO=1000.............. MILLI= thousandth

1kg is 1000 grams

1 milligram is one thousandth of a gram, so a 1 gram = 1000mg.

in 36 kg, then there are 36 * 1000 grams.

and in (36*1000) grams there are (36*1000)*1000 mg, 36,000,000 mg.

Can someone please help me out!!?

HACTEHA [7]

Answer:

x = 7

Step-by-step explanation:

$\frac{10}{8} = \frac{3x-6}{12}$ --> Triangle Similarity Theorem

120 = 8(3x - 6) --> Cross Multiplying

120 = 24x - 48 --> Distributing the 8

24x - 48 + 48 = 120 + 48 --> Adding 48 on both sides

24x = 168 --> Simplifying

24x/24 = 168/24 --> Divide 24 on both sides

x = 7 --> Simplifying

Tobias sent a chain letter to his friends, asking them to forward the letter to more friends. The number of people who receive t

malfutka [58]

Answer:

$P(t)=37\times (4)^{(t/9.1)}$

Explanation:

The number of emails is multiplied by 4 every 9.1 weeks.

Thus, since Tobias initially sent the chain letter to 37 friends, the number of letters will grow as per this geometric series:

Start: 37 letters

In 9.1 weeks: 37 × 4

In 2 × 9.1 weeks: 37 × (4)²

In 3 × 9.1 weeks: 37 × (4)³

As you see, the exponent is the number of weeks divided by 9.1

Thus, if your variable is the number of weeks, t, then the exponent is t/9.1

And the exponential function, P(t) will be:

$P(t)=37\times (4)^{(t/9.1)}$
