Answer: Choice 2: 4/5 • 4/5 • 4/5 = 64/125

Step-by-step explanation: The exponent tells you how many times you have to multiply the 4/5. Since the exponent is 3, we know to multiply 4/5 with itself 3 times, like this: 4/5 • 4/5 • 4/5, which will get us 64/125

Answer:

\huge\boxed{\sf Option \ 2}

Step-by-step explanation:

\sf (\frac{4}{5})^3 \\\\

This means that 4/5 repeats itself 3 times.

So,

\sf = \frac{4}{5} * \frac{4}{5} * \frac{4}{5} \\\\= \frac{64}{125} \\\\\rule[225]{225}{2}

Hope this helped!

The length of a chord is 22 cm and that chord is 5 cm from the center of the circle. What is the length of the diameter ?
Kamila [148]

Answer:

The circle's diameter is approximately 24.2 cm

Step-by-step explanation:

You can use the Pythagorean theorem to solve this, my realising that the 5cm distance of the chord represends one side of a right triangle, half the chord's length is the other side, and the hypotenuse of the two is the circle's radius.  With that we can say:

r = √(11² + 5²)

r = √(121 + 25)

r = √146

Now we can double that to get the diameter:

r = 2√146

r ≈ 24.2

The men s clothing buyer had a group of 50 jackets priced at $250 each that was selling very slowly. To stimulate sales of these
erastovalidia [21]

Answer:

The answer is $3000.

Step-by-step explanation:

The men's clothing buyer had a group of 50 jackets priced at $250 each.

Total price of jackets = 50\times250=12500 dollars

The buyer reduced the price of the jackets in that group to $200 and 40 jackets were sold.

So, the price for selling 40 jackets is = 40\times200=8000 dollars

Remaining jackets =50-40=10

These were sold at $150 each, totaling to = 10\times150=1500 dollars

So, overall money earned by reducing prices both time = 8000+1500=9500 dollars

And the markdown in dollars = (original price before reducing) minus (educed total price)

= 12500-9500=3000 dollars

So, the answer is $3000.

Which of the following expressions is the conjugate of a complex number with 2 as the real part and 3i as the imaginary part?
lbvjy [14]
The complex number is represented as 2 + 3i. The conjugate of the complex number is the number with equal real part and imaginary part equal in magnitude but opposite in sign. Therefore, the correct answer is option B. The conjugate of the complex number is 2 − 3i.

Let f(x)=ln(3x)+2.5 .
Cerrena [4.2K]
For this case what we should do is evaluate the function in each of the points from 2 to 7 and then find the average.
 We have then:
 f (x) = ln (3x) +2.5.
 f (2) = ln (3 * 2) + 2.5 = 4.291759469
 f (3) = ln (3 * 3) + 2.5 = 4.697224577
 f (4) = ln (3 * 4) + 2.5 = 4.98490665
 f (5) = ln (3 * 5) + 2.5 = 5.208050201
 f (6) = ln (3 * 6) + 2.5 = 5.390371758
 f (7) = ln (3 * 7) + 2.5 = 5.544522438
 Then the average is:
 Average = (4.291759469 + 4.697224577 + 4.98490665 + 5.208050201 + 5.390371758 + 5.544522438) / (6) = 5.019472516
 nearest hundredth
 5.02
 Answer:
 the average rate of change of f (x) from 2 to 7 is  5.02
