Answer:

Out of given options only (1) is equivalent to given expression.

\frac{1}{16}=(\frac{1}{2})^4

Step-by-step explanation:

Given: expression 1 divided by 16.

We have to choose an equivalent fraction for the given fraction.

Consider the given expression 1 divided by 16 mathematically written \frac{1}{16}

We will evaluate the given options and check which one will give same fraction.

1) (\frac{1}{2})^4

We can write it as \frac{1}{2^4}=\frac{1}{16}

2) (\frac{1}{4})^4

We can write it as \frac{1}{4^4}=\frac{1}{256}

3) (\frac{1}{2})^2

We can write it as \frac{1}{2^2}=\frac{1}{4}

Thus, out of given options only (1) is equivalent to given expression.

\frac{1}{16}=(\frac{1}{2})^4

Latoya has b decks of cards . Each deck has 52 cards in it , what is the expression for the total numbers of cards latoya has
Lerok [7]

Answer:

52b

Step-by-step explanation:

She has 52 cards per deck, and b decks.

This means she has 52b cards.

How this works:

For 1 deck, she has 52 cards, or 52×1 cards.

For 2 decks, she has 104 cards, or 52×1 cards.

For 5 decks, she has 260 cards, or 52×5 cards.

For 10 decks, she has 520 cards, or 52×10 cards.

Therefore, for b decks, she has 52×b, or 52b cards.

Janaya buys a postcard from each travel destination she visits. Before starting her travels this year, Janaya had 20 postcards.
MrRa [10]

Answer:

The percentage increase in Jayana's postcard collection is 15%

Step-by-step explanation:

Jayana had 20 postcards last year

With 3 more postcards this year

From the given equation Quantity = Percent x Whole

Here;

Let P = Percent/100%

Quantity = Increment in postcard = 3 postcards

Whole = The total postcards from last year = 20 postcards

Hence,

3 postcards = P x 20 postcards

P = 3/20 = 0.15

Recall P = Percent/100%

∴ Percent = P x 100% = 0.15 x 100% = 15%

The percentage increase in Jayana's postcard collection is 15%

Which equation represents a population of 250 animals that decreases at an annual rate of 21% ?
victus00 [196]

Answer: Choice C.  p = 250(0.79)^t

Work Shown:

p = a*b^t

p = a*(1+r)^t

p = 250*(1+(-0.21))^t

p = 250(0.79)^t

Note that r = -0.21 is negative to indicate we have exponential decay.

Use the information to answer the following question.
trasher [3.6K]

Answer:

D is the answer

Step-by-step explanation:

For a: g(x) = 1 when x = 1, for f(x) 1^2 - 2(1) + 2 = 1, a is true.

For b: Both functions do have all real numbers for their domain, b is true

For c: the y-intercept of g(x) is x = 0, for f(x), it is 0^2 - 2(0) + 2 = 2, c is true

For d: g(3) = 7, f(3) = 3^2 - 2(3) + 2  = 5, d is false.
