Answer:

33,3

Step-by-step explanation:

Set it up as a proportion in correspondence with their unit of measurement:

\frac{16}{21,3} = \frac{25}{?} → \frac{[21,3][25]}{16} → \frac{532,5}{16} = 33,28125 \\ \\ 33,3 ≈ P

I hope this is correct, and as always, I am joyous to assist anyone at any time.

y = 2x squared + 5x -3 can be written in the form y= 2( x+a) squared + b . Find the value of a and the value of b.
Elan Coil [88]

General vertex form:

y = m(x − a)² + b  \: with  \: vertex \:  at \:  (a, b)

Given :

y = 2x² + 5x  - 3

Extract "spread factor" m

y = 2( x² +  \frac{5}{2} x) - 3

Complete the square

y = 2(x²  +  \frac{5}{2}x + ( \frac{5}{4})²) - 3

- 2( \frac{5}{4})²

Write as a squared binomial and simplify the constant

y = 2(x +  \frac{5}{4})² - 6 \frac{1}{8}

Re-write to match signs of standard general form:

y = 2(x - ( -  \frac{5}{4}))² \:  + ( - 6 \frac{1}{8})

Simplify: (-3x^3+2x^2+4x)-(8x^4-5x^3+6x^2-2x
sergejj [24]

Answer:

−8^4+2^3−4^2+6

Step-by-step explanation:

Distribute the - to 8x^4-5x^3+6x^2-2x:

-8x^4+5x^3-6x^2+2x

Now simplify:

-3x^3+2x^2+4x-8x^4+5x^3-6x^2+2x= −8^4+2^3−4^2+6

Hope this helps!

Help please!<br> <br> Lines a and b are parallel.<br> <br> What is the measure of angle m?
AlexFokin [52]
So the transversal (line that crosses lines a and b) is 180 since its a straight line. given the angle degree 125, you can do 180-125 to get angle m.
