B.Determine the quadratic function given the following zeroes:​

Mathematics
1 answer:
Stella [2.4K]3 years ago

Answer: Read Sol.

Step-by-step explanation: To solve these, call each given zero = z. The function is when given a zero that is an integer (x-z1)(x-z2)(x-z3)... so on until all zeroes are used. This works for fractions also. But when you have irrationals, you will have to make sure each irrational solutions conjugate is there. So if a given zero is 2-sqrt3, then always 2+sqrt3 will also be a 0. Likewise, if given -4-sqrt7, then -4+sqrt7 will also always be a zero. Use this logic to solve them very quickly! I hope this helps!

Find the missing side lengths. Leave your answers as radicals in simplest form.
Citrus2011 [14]

This is the isosceles right triangle, the diagonal of a square, the thing that so upset the Pythagoreans. The two sides and diagonal of a square are in ratio 1:1:\sqrt{2} so we get


u = v =  8


We could have also gotten this using Trig:


u = (8 \sqrt{2}) \sin 45^\circ = 8 \sqrt{2}/\sqrt{2} = 8


v = (8\sqrt{2})\cos 45^\circ = 8


Or by recognizing u=v because remaining angle is 45 so this must be isosceles so


u^2 + u^2 = (8 \sqrt{2})^2


2u^2 = 2 (8^2)


u = 8

Answer:

c = 9/16

Step-by-step explanation:

<h3>step1</h3>

(a-b)²

a² - 2ab + b²

here a = x

        b = ?

   

so

x² - (2)(x)(?) + ?²

Now we can see that -(2x)? = -3x/2

                                    -2x? = -3x/2

cancel -x on both sides

2? = 3/2

? =  3/2 * (2)

? =  3/4

so b = 3/4

<h3>step2</h3>

(x² - 3x + 9/16) = (x-3/4)²

so from the expression we can see that C = 9/16
