what is the factored form of a fourth degree polynomial function with coefficients that has -3,1and 1+5i

1 answer:

4 0

Complex factors are
(x +3)(x -1)(x -1 -5i)(x -1 +5i)

If you want the complex factors combined to a real factor, the factorization is
(x +3)(x -1)(x² -2x +26)

What is the tax (8%) on a $2.50 magazine

Gala2k [10]

2.50X.08=.2
tax is 20 cents

8 percent =.08 as a decimal. to get the decimal of a percent pretend 8 percent is an 8 with an invisible decimal point at its right. so 8% is 8.0. to get a decimal of a percent, move the point two times to the left, and you will put in a 0 for the blank. so its ._8, where he blank is 0 and so 8%=.08

Write (1,4) and(-1,1) in standard form, slope intercept form, and point slope form

gogolik [260]

Answer:

See below

Step-by-step explanation:

Standard form:

ax + by = c

Slope intercept form:

y = mx + b

Point slope form:

y - y₁ = m(x - x₁)

Use the given points and find the slope:

m = (y₂ - y₁) / (x₂ - x₁)
m = (1 - 4) / (- 1 - 1) = - 3/ - 2 = 3/2 = 1.5

Point-slope form:

y - 4 = 1.5(x - 1)

Convert this to slope-intercept form:

y - 4 = 1.5(x - 1)
y = 4 + 1.5(x - 1)
y = 4 + 1.5x - 1.5
y = 1.5x + 2.5

Convert this into standard form:

y = 1.5x + 2.5
2y = 3x + 5
3x - 2y = - 5
