4 0

Answer:

24

Step-by-step explanation:

x/2-3x/4+5x/8=9

Or,(4*x-2*3x+5x)/8=9. (taking LCM)

Or, (4x-6x+5x)/8=9

Or, 3x=9*8

Or, x = 72/3

so, x=24.

Step-by-step explanation:

Y =  Ax2 Bx C

Enter coefficients here >>>  -4 97 -568

   

Standard Form: y = -4x²+97x-568    

-24.25 -12.125 147.015625 -588.0625 20.0625

Grouped  Form: No valid Grouping      

   

Graphing Form: y = -4(x-12.13)²+20.06    

     

Factored Form: PRIME    

   

Solution/X-Intercepts: 14.36 AND 9.89    

   

Discriminate =321 is positive, two real solutions    

   

VERTEX: (12.13,20.06)     Directrix: Y=20.13

WILL MARK BRAINLIEST!!!!PLZ HELP!!!! An expression is shown below: 3pf2 − 21p2f + 6pf − 42p2 Part A: Rewrite the expression by f
Lesechka [4]

Answer:

See below.

Step-by-step explanation:

So, we have:

3pf^2-21p^2f+6pf-42p^2

PART A:

Find the GCF. Notice that we have a 3 in every term and a p in every term. Thus, the GCF is 3p:

3p(f^2-7pf+2f-14p)

This is the most we can do.

PART B:

Continue from where we left off. Factor the entire expression:

3p(f^2-7pf+2f-14p)\\3p(f(f-7p)+2(f-7p))\\3p((f+2)(f-7p))

An arc subtends a central angle measuring \dfrac{\pi}{2}
Agata [3.3K]

Arc Length is 1/4th of the circumference .

<u>Step-by-step explanation:</u>

Here we need to find fraction of the circumference is this arc when An arc subtends a central angle measuring \dfrac{\pi}{2} radians ! Let's find out :

We know that circumference of an arc subtending a central angle of x is :

⇒ Arc = \frac{Angle}{360}(2\pi r)

⇒ Arc = \dfrac{\frac{\pi}{2}}{360}(2\pi r)

⇒ Arc = \frac{90}{360}(2\pi r)

⇒ Arc = \frac{90}{90(4)}(2\pi r)

⇒ Arc = \frac{1}{4}(2\pi r)

⇒ Arc = \frac{1}{4}(Circumference)

Therefore , Arc Length is 1/4th of the circumference .
