If sin theta = cos theta then find the value of theta

Ksenya-84 [330]

Step-by-step explanation:

$\because \sin \theta = \cos \theta \\ \\ \therefore \: \sin \theta = \sin(90 \degree - \theta) \\ \\ \therefore \: \theta = 90 \degree - \theta \\ \\ \therefore \: \theta + \theta= 90 \degree \\ \\ \therefore \: 2\theta = 90 \degree \\ \\\therefore \: \theta = \frac{90 \degree }{2} \\ \\ \huge \orange{\boxed{\therefore \: \theta = 45 \degree}}\\ \\$

Factoring quadratics

Stells [14]

You need to bring the right to the left
2X^2-9x-x^2+20=0
So you combine and get
X^2-9x+20
(X-4)(X-5)
Cuz -4 times -5 =20 and -4+-5=-9
So solve X-4=0. X-5=0
X=4. X=5

Form a polynomial whose zeros and degree are given.

lisabon 2012 [21]

Answer:

Zeros: 5, multiplicity 1; -4 multiplicity 2; degree 3

y=1(x-5)^1(x+4)^2

y=(x+4)^2(x-5)

y=(x^2+8x+16)(x-5)

y=x^3+8x^2+16x-5x^2-40x-85

y=x^3+3x^2-24x-85
