Find the discriminant of x²+6x+9=0

Rainbow [258]

Answer:

x²+6x+9=0

x²+3x+3x+9=0

x(x+3)+3(x+3)=0

(x+3)(x+3)=0

either

x+3=0

x=-3

x+3=0

x=-3

Step-by-step explanation:

next method

x²+6x+9=0

x²+2×x×3+3²=0

it is in formula of (x+y)²

(x+3)²=0

x+3=√0

x+3=0

x=-3

For each of the following scenarios state whether H0 should be rejected or not. State any assumptions that you make beyond the i

scoundrel [369]

Answer:

a) $H_0 :\mu = 4\\ H_1 : \mu \neq 4$ , n = 15 , X=3.4 , S=1.5 , α = .05

Formula : $t = \frac{x-\mu}{\frac{s}{\sqrt{n}}}$

$t = \frac{3.4-4}{\frac{1.5}{\sqrt{15}}}$

$t =-1.549$

p- value = 0.607(using calculator)

α = .05

p- value > α

So, we failed to reject null hypothesis

b) $H_0 :\mu = 21\\ H_1 : \mu < 21$ , n =75 , X=20.12 , S=2.1 , α = .10

Formula : $t = \frac{x-\mu}{\frac{s}{\sqrt{n}}}$

$t = \frac{20.12-21}{\frac{2.1}{\sqrt{75}}}$

$t =-3.6290$

p- value = 0.000412(using calculator)

α = .1

p- value< α

So, we reject null hypothesis

Assume α = .05

p-value = 0.061.

p- value > α

So, we failed to reject null hypothesis

Write an equation in point-slope form of the line that passes through the point (−3,6) and has a slope of 5.

strojnjashka [21]

Answer:

Below in bold.

Step-by-step explanation:

Point slope form is y - y1 = m(x - x1)

where m = the slope of the line and (x1, y1) is a point on the line.

Here m = 5, x1 = -3 and y1 = 6.

So we have:

y - 6 = 5( x - (-3))

y - 6 = 5(x + 3) (Answer)
