Answer:

Which i think is the first one, there may just be a typing error.

Step-by-step explanation:

A polynomial of order n has the following format:

f(x) = a(x - x_{0})(x - x_{1})...(x - x_{n-1})

In which a is the leading coefficient, x_{0}, x_{1},..., x_{n-1} are the roots.

If a root appears m times, they are said to have multiplicity m.

Leading coefficient of 1 and roots 21 and 31 with multiplicity 1

f(x) = 1(x - 21)(x - 31)

So the correct answer is:

f(x) = 1(x - 21)(x - 31)

Which i think is the first one, there may just be a typing error.

Please help with this precalc!!! i desperately need help
Paladinen [302]

Step-by-step explanation:

4 is the A or Ampltiude

To find the period set it equal to 2 pi/B

\frac{2\pi}{b}  =  \frac{6}{1}

\frac{b}{2\pi}  =  \frac{1}{6}

b=

\frac{2\pi}{6}

b=

\frac{\pi}{3}

There is no phase shift

The midline or d or vertical shift is 1.

Our equation for 8 is

4 \sin( \frac{\pi}{6} x)  + 1

9.Use sin function. The a value is 2 or -2 your choice.

Set up the period equal to the equation

\frac{2\pi}{b}  =  \frac{\pi}{3}

\frac{b}{2\pi}  =  \frac{3}{\pi}

b =  \frac{3}{\pi}  \times 2\pi

Which equal 6.

B=6

There is no C and the D and Vertical Shift is 1.

Our equation is

2 \sin(6x)  + 1

4.6.3 Test (CST): Linear Equations
inn [45]

The slope of the green line if the lines are perpendicular is -1/4

<h3>Perpendicular lines</h3>

For two lines two be perpendicular, the product of their slope must be -1. Let the slope of the red and green line be m1 and m2.

Given the following

Slope of red line = 4

According the definition

4m2 = -1

m2 = -1/4

Hence the slope of the green line if the lines are perpendicular is -1/4

likoan [24]
A = 1/2 (l × w)
A = 1/2 (8 1/2 × 6)
A = 1/2 (17/2 ×12/2)
A = 1/2 (204/4)
A = 1/2 (51)
A = 25 1/2  OR  25.5 in

Answer:

I don't know if this is correct but id say

5500 \times  \frac{2}{100} = 55 \times 2 = 110

Step-by-step explanation:

the interest is 2 % so you'd say 2/100 times the amount of money in the interest so that is 2% of 5500

the interest is 110
