Which equation is equivalent to f(x) = 16x4 – 81 = 0?

Vesna [10]

Answer:

The equivalent expression is:

$16x^4-81=(4x^2-9)(4x^2+9)$

Step-by-step explanation:

We have been given the equation:

$f(x)=16x^4-81=0$

Equivalent expression can be computed by solving the expression ai its maximum.

We can factorize the given equation:

By using $a^2-b^2=(a+b)(a-b)$

Here, $a=4x^2,b=9$

Hence, we get the equation below:

$16x^4-81=(4x^2-9)(4x^2+9)$

Therefore, the equivalent expression is:

$16x^4-81=(4x^2-9)(4x^2+9)$

A coin favors heads when tossed and there are 15 heads in 18 tosses

Alexxandr [17]

This is not correct. You might think you are "on a roll" but the probability of heads on any toss is just as likely as the probability of tails because each coin toss is an independent event, meaning, two events related in such a way that knowing about the occurrence of one event has no effect on the probability of the the other event. This would hold true if you have tossed these 15 heads and you believe that tails "are due". It is an independent event.

A linear function has the same y-PLEASE PLEASE HELP!!!!intercept as x+2y=10 and it’s graph contains the point (9,7) find the slo

Anastasy [175]

Answer:

I think it is 2/9 or 0.22

Step-by-step explanation:

You know they have the same y intercept, so first you should find the y intercept of the givern equation.

x+2y = 10

2y = -x + 10 [subtract x]

y = -.5x + 5 [divide by 2]

Now you have the equation in graph form, and know the y intercept is 5.

If the unknown function has the same y intercept, you know it contains the point (0,5), and it is given that it includes the point (9,7)

now that you have two points, you can use slope formula.

(y2 - y1)/(x2-x1)

(change in y)/(change in x)

so,

(7-5)/(9-0) = 2/9 = 0.2

someone please correct me if i'm wrong:)
