Let's see

\\ \rm\rightarrowtail 5x^2-9x+4=0

\\ \rm\rightarrowtail 5x^2-5x-4x+4=0

\\ \rm\rightarrowtail 5x(x-1)-4(x-1)=0

\\ \rm\rightarrowtail (5x-4)(x-1)=0

\\ \rm\rightarrowtail x=4/5,1

Leokris [45]

Answer:

Event A = white marble is selected

Event B = blue marble is selected

P(A) = 5/10 = 1/2

p(B) = 5/10 = 1/2

Probability that A and B are independent events is:

P(A∩B) = 1/2 × 1/2

Answer: 1/4

Q7) A rectangular piece of land measures 8 m by 5m. It is to be fenced with four lines of wire. What length of wire is needed fo
Harrizon [31]

Answer:

26 m

Step-by-step explanation:

Find what length is needed for fencing by finding the perimeter of the land.

Use the perimeter formula, P = 2l + 2w

Plug in the length and width:

P = 2l + 2w

P = 2(8) + 2(5)

P = 16 + 10

= 26

So, the length of wire needed is 26 m

What is the length of an arc with a central angle of 23π radians and a radius of 24 cm?
dalvyx [7]
We can solve for the arc length using the formula shown below:
Arc Lenght = 2pi*r(central angle/360)

We need to convert the central angle such as:
Central angle = 23pi rad * (180°/pi rad) = 23*180
Radius = 24cm 

Solving for arc length:
Arc length = 2*3.14 *24*(23*180/360)
Arc length = 1733.28 cm

HELP PLEASE ASAP!!!!!!
lesya692 [45]
Alright, as we can see the large rectangle's area is 4x² + 9x + 2.

You can also see that gray rectangle's area inside the larger rectangle is
x² + 4x + 3.

So if we want to find the white area in-between the two rectangles we will need to SUBTRACT the two formulas! (Subtract the large rectangle from the smaller one)

To do so we will need to subtract the like terms.
The like terms are 4x² and x², 9x and 4x, 2 and 3!

So first we do 4x² - x² and you get 3x²
Next, we do 9x - 4x and you get 5x
Lastly, we do 2 - 3 and you get -1

Now we put our solutions together and you get...

3x² + 5x - 1

This is the are for the white region of your problem. :D  glad to help
