Find the formula for df^-1/dx. f(x)=(7-x)^3

1 answer:

7 0

Here is the equation to solve the problem above:

f(x) = (7-x)^3
y = (7-x)^3

switch y and x
x = (7 - y)^3

third root of x = 7 - y
-y = 3rootx - 7

so:f′(x)=3^√x−7

A company manufactures cell phones. In August, a random sample of 125 cell phones was inspected, and 3 phones were found to be d

german

Answer:

192

Step-by-step explanation:

To find how many phones are expected to be defective, we need to represent the values in a fraction.

$\dfrac{x}{8000}=\dfrac{3}{125}$

x = number of defective phones

Now we can solve this using algebra.

To get the value of x we need to multiply both sides by 8000 to leave x alone.

$x=\dfrac{3}{125}(8000)$

$x=0.024(8000)$

$x=192$

So around 192 cell phones are expected to be defective out of 8000 phones.

Elena is designing a paint can with thickness ttt millimeters and height hhh centimeters. She calculates that the thickness of t

Degger [83]

Answer:

$t \ge h$ and $t + 0.5h \le 12.0$

Step-by-step explanation:

Given

$t= thickness$

$h =height$

From the first statement, we have that:

$t\ mm \ge 0.1 * h\ cm$

Convert mm to cm

$t\ * 0.1*cm \ge 0.1 * h\ cm$

$t\ *0.1 \ge 0.1 * h$

Divide both sides by 0.1

$t \ge h$

From the second statement, we have that:

$Cost \le 12.2$

Substitute 0.2 + t + 0.5h for Cost

$0.2 + t + 0.5h \le 12.2$

Collect Like Terms:

$t + 0.5h \le 12.2-0.2$

$t + 0.5h \le 12.0$

So, the inequalities are:

$t \ge h$ and $t + 0.5h \le 12.0$
