Answer: 2 × 3 × 5 × 11 = 330.

Step-by-step explanation: Since, the prime factors of 6600 are 2, 3, 5, 11. Therefore, the product of prime factors = 2 × 3 × 5 × 11 = 330.

Graph f(x) = log5 (x-3).

Natali5045456 [20]

Step-by-step explanation:

We want to graph:

$f(x) =\log_{5}(x - 3)$

We first graph the parent function

$g(x) =\log_{5}(x)$

This parent function has x-intercept at (1,0) and it is asymptotic to the y-axis.

We then shift the graph of the parent function 3 units right, to obtain the graph of

$f(x) =\log_{5}(x - 3)$

The new x-intercept will be (4,0) and vertical asymptote will now be x=3.

lukranit [14]

Answer: 25 computers will be selected

Step-by-step explanation:

Where: Z -value at 95% confidence = 1.96; SD = Standard deviation = 10 minutes; N = Sample size; Margin error = 4 minutesSubstituting;4 = 1.96*10/Sqrt (N)Sqrt (N) = (1.96*10)/4 = 4.9N = 4.9^2 = 24.01 ≈ 25

lol, i was doing just fine on this hw until this. Pleeze help! solve for d+2 > 6. I am offering twenty-five Points

Hello from MrBillDoesMath!

Answer:

d>4

Discussion:

I understand the question is asking us to solve for "d" in the inequality:

d + 2 > 6 => subtract 2 from both sides

d + 2 -2 > 6 - 2 => as 2 - 2 = 0

d > 6 -2 = 4

If I have misunderstood the question, please tell me.

Thank you,

MrB

An escalator from the ground floor to the second floor of a department store is 110 ft long and 32 ft vertical. What is the esca

grigory [225]

Answer: 16.91°

Step-by-step explanation:

1. You can draw a right triangle as you can see in the figure attached.

2. Then you can calculate the angle of elevation (α) as following:

$\alpha=arcsin(\frac{opposite}{hypotenuse})$

Where:

$opposite=32\\hypotenuse=110$

3. Now you must substitute these values. Then, the angle of elevation is:

$\alpha=arcsin(\frac{32}{110})$

$\alpha=16.91\°$
