You did:

5 episodes / 4 hours = 1.25 episodes/hour

You found how many episodes they watched in one hour, when you should have found how many hours they watched one episode. This is because you need to find how long it took them to watch 24 episodes.


So instead:

4 hours / 5 episodes = 0.8 hours/episode


Then you multiply 0.8 and 24 = 19.2 hours

How would you do number 12 and 15?
Gnesinka [82]

Answer:

x_1=x_2=-\dfrac{2}{3}

Step-by-step explanation:

For the quadratic equation ax^2+bx+c=0 the discriminant is defined as

D=b^2-4ac

and the quadratic formula for the roots gives us two roots:

x_1=\dfrac{-b-\sqrt{D}}{2a}

and

x_2=\dfrac{-b+\sqrt{D}}{2a}

For the equation 9x^2 +12x+4=0 use quadratic formula to find roots:

D=12^2-4\cdot 9\cdot 4=144-144=0

So,

x_1=x_2=\dfrac{-12\pm \sqrt{0}}{2\cdot 9}=-\dfrac{12}{18}=-\dfrac{2}{3}

Find f(g(3)) given:<br> *<br> f (x) = 2x2 – 1<br> g(x) = 3x<br> h(x) =<br> j(x) = x - 5
bezimeni [28]

Answer:

161

Step-by-step explanation:

Given the functions

f (x) = 2x^2 – 1

g(x) = 3x

we are to find f(g(3))

First look for the composite function f(g(x))

f(g(x)) = f(3x)

f(3x)  = 2(3x)² - 1

f(3x)  = 2*9x² - 1

f(3x)  = 18x² - 1

f(g(x)) =  18x² - 1

Substitute x  = 3 into the result

f(g(3)) = 18(3)² - 1

f(g(3)) = 18*9- 1

f(g(3)) = 162-1

f(g(3)) = 161

Hence f(g(3)) is 161

Solve √(2x-5) - √(x+6) = 0.
nika2105 [10]

Answer:

The solution to this question is 11.

Step-by-step explanation:

Given that

√(2x-5) - √(x+6) = 0

√(2x-5) =√(x+6)  equation (1)

square of the equation (1)

(√(2x-5))^2 =(√(x+6))^2

we know that √a*√a=(√a)^2=a.So

2x-5=x+6          after square.

2x-x=6+5                exchange value

x=11
