Answer:

Step-by-step explanation:

The formula of a circumference of a circle:

$C=d\pi$

d - diameter

We have d = 4m.

Substitute:

$C=4\pi\ m$

Use 3.14 for π:

$C\approx4(3.14)=12.56\ m$

You design a new app for cell phones. Your revenue for x downloads is given by f(x) = 3x Your profit

Snowcat [4.5K]

Answer:

p = 2.7x - 20

p(90) = $223

Step-by-step explanation:

revenue → f(x) = 3x ,where x is the number of downloads.

the statement “Your profit p is $20 less than 90% of the revenue for x downloads”

means

$p=90\% f\left( x\right) -20$

means

$p=\frac{90}{100} \times f\left( x\right) -20$

means

$p=\frac{9}{10} \times (3x) -20$

means

$p=\frac{9}{10} \times (3x) -20$

means

$p=2.7x -20$

………………………………

the profit for 90 downloads :

= p(90)

= 2.7×(90) - 20

= $223

Part A: If (7^2)^x = 1, what is the value of x? Explain your answer. (10 points)

Alex777 [14]

Answers:Part A: The value of x is 0.Part B: X can be any real number.
In Part A, you have to first evaluate 7^2. This is 49. Now, write the equation 49^x = 1. We know that if you raise any number to 0, then the answer is 1.
In Part B, you have to first evaluate 7^0, that is 1. Now, we have the equation 1^x = 1. In this case, 1 raised to any exponent is still only 1. Imagine 1^17, this would be 1 times itself 17 times or just 1.
Therefore any number will work in Part B.

Domain is the x-coordinate and range is the y - coordinate

$\therefore \: domain = \{ - 5, \: - 2, \: 1, \: 2 \} \\ \\ \&\: range = \{ - 3, \: 1, \: 4, \: 5\}$
