Which expression is equivalent to y times y times y times z times z times z times z? y cubed z Superscript 4 12xy (y z) Superscr

Rina8888 [55]

Answer:

Option 1 - y cubed z superscript 4

Step-by-step explanation:

Given : Expression y times y times y times z times z times z times z.

To find : Which expression is equivalent to given expression ?

Solution :

Re-write the expression as,

$y \times y \times y \times z \times z \times z \times z$

Write the number of time value repeat itself as the power,

$y \times y \times y \times z \times z \times z \times z=y^3\times z^4$

$y \times y \times y \times z \times z \times z \times z=y^3z^4$

or we can say that the expression is y cubed z superscript 4.

Therefore, option 1 is correct.

The world's population is expected to grow at a rate of 1.3% per year until at least the year 2020. In 1994 the total population

Marina CMI [18]

The solution to your problem is as follows:

Given:
P₀ = 5,642×10^6 people,
i = 1.3% = 0.013 per year,
n = 2020 - 1994 = 26 years,

We get:
<span>
Pn = P₀ e^(i.n) </span>
. . .= 5,642×10^6×e^(0.013×26)
<span>. . .= 7,911×10^6 people

Therefore, the </span>the world's predicted population in the year 2020 is <span>7,911×10^6 people.

im, Paco, Maria, and Jenny are standing in line for lunch. Jenny is standing between Paco and Maria, and Paco’s position in line

Zanzabum

Answer:

The person standing at the fourth position is Maria.

Step-by-step explanation:

We are given that,

There are four students standing in line for lunch namely, Tim, Paco, Maria and Jenny.

Now, as Jenny is standing between Paco and Maria.

So, we have the possibility, P J M.

Also, as Paco is standing at an odd numbered position.

So, we have, either Paco stands at 1st or 3rd position.

Further, it is given that, Tim is not standing on either end of the line.

<em>So, we get, the possibilities,</em>

P J T M and M J P T.

But, in M J P T, T=Tim is standing at the end of the line, which is not possible.

So, the final positioning is given by, P J T M.

Hence, the person standing at the fourth position is Maria.

HELP ASAP Solve log7 b > 2. Question 18 options: b > 7 b > 49 b > 2–7 b > 14

labwork [276]

Answer: Second Option

$b > 49$

Step-by-step explanation:

We have the following expression:

$log_7(b) > 2$

We have the following expression:

To solve the expression, apply the inverse of $log_7$ on both sides of the equality.

Remember that: $b ^ {log_b (x)} = x$

So we have to:

$7^{log_7(b)} > 7^2$

$b > 7^2$

$b > 49$

The answer is the second option
