nevsk [136]

See this question as Ratio.

Amplifiers : Time Taken in minutes

5 : 30

5x= 125
x= 25

so

5*25 : 30*25

125 : 750

750 minutes.
12 hours 30 minutes.

Step-by-step explanation:

54^2 + a^2 = 90^2

2916 + a^2 = 8100

a^2 = 8100 - 2916

a^2 = 5184

take the square root of 5184

a = 72

you could have also guessed that its a 3 4 5 right triangle

all the sides are multiples of 3 4 or 5

What is the instataneous rate of change at x=2 of the function f given by f(x)= x^2-2÷x-1

Dima020 [189]

Answer:

4.5

Step-by-step explanation:

To find the instantaneous rate of chance, take the derivative:

$f(x) = {x}^{2} - \frac{2}{x} - 1 \\ \frac{d}{dx} f(x) = 2x + \frac{2}{ {x}^{2} }$

Remember to use power rule:

$\frac{d}{dx} {x}^{a} = a {x}^{a - 1}$

To differentiate -2/x, think of it as:

$- 2 {x}^{ - 1}$

Then, substitute 2 for x:

$2(2) + \frac{2}{ {2}^{2} } \\ 4 + \frac{2}{4} = 4.5$
