1 answer:

8 0

The answer to this question using the quadratic formula is x= -1+3√5/2 and x=-1-3<span>√5/2
</span>that is a square root, or, 3 times the square root of 5 ALL over 2, except for the 1. Same with the other one.

Explain why f(x) = x2+4/x2-x-2 is not continuous at x = 2.

xxTIMURxx [149]

Answer: Option a.

Step-by-step explanation:

Make the denominator equal to zero and solve for x:

Factor the quadratic equation. Find two number whose sum is -1 and whose product is -2. Then:

$x^{2}-x-2=0\\(x-2)(x+1)=0\\x=2\\x=-1$

Then, as you can see the value x=2 makes the denominator equal to zero and the division by zero does not exist. Therefore you can conclude that the function shown in the problem is not defined at x=2

The answer is the option a.

Answer: Order will be F,D,C and Fourth Option is correct and x = 10

Step-by-step explanation:

Since we have given that

$\sqrt{6x+4}=8$

We first transpose the square root to the right , so it becomes square of 8,i.e.

$6x+4=8^2\\\\6x+4=64$

Now, transpose 4 to the right so it will get subtract from 64 i.e.

$6x=64-4\\\\6x=60$

Since 6 is multiplied to x on tranposing it will get divided by 60 i.e.

$x=\frac{60}{6}\\\\x=10$

Hence, on simplification, we get x=10.

Hence , the order is F,D,C.

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
