Answer:

9. First Five terms

If n=0. Then,

$\frac{4(0) - 5}{2}$

$\frac{0 - 5}{2} = \frac{ - 5}{2}$

If n=1. Then,

$\frac{4(1) - 5}{2}$

$\frac{4 - 5}{2} = \frac{ - 1}{2}$

If n=2. Then,

$\frac{4(2) - 5}{2}$

$\frac{8 - 5}{2} = \frac{3}{2}$

If n=3. Then,

$\frac{4(3) - 5}{2}$

$\frac{12 - 5}{2} = \frac{7}{2}$

If n=4. Then,

$\frac{4(4) - 5}{2}$

$\frac{16 - 5}{2} = \frac{11}{2}$

If n=5. Then,

$\frac{4(5) - 5}{2}$

$\frac{20 - 5}{2} = \frac{15}{2}$

If n=6. Then,

$\frac{4(6) - 5}{2}$

$\frac{24 - 5}{2} = \frac{19}{2}$

What is the y-intercept of the quadratic function f(x) = (x – 6)(x – 2)? (0,–6) (0,12) (–8,0) (2,0) Mark this and return Save an

juin [17]

the y intercept is the constant term on the x side

-6 * -2 which is 12

we can foil this out to see that

(x-6) (x-2)

x^2 -6x -2x+12

x^2 -8x+12

so the y intercept is (0,12)

You are designing a rectangular swimming pool that is to be sent into the ground. The width of the pool is 5 feet more than the

Vikentia [17]

Answer: depth = 5 ft

width = 10 ft

length = 40 ft

Step-by-step explanation:

d = depth

width = d + 5

length = d + 36

Volume = length x width x depth = 2000 cf

d(d+35)(d+5) = 2000

d( $d^{2}$ + 40d + 175) = 2000

d^3 + 40d^2 + 175d = 2000

rewrite in standard cubic polynomial form : ax3 + bx2 + cx + d = 0

d^3 + 40(d^2) + 175d - 2000 = 0

Find the roots of the cubic polynomial:

factors of 2000 are 1, 5, 10 15, 20, etc.

Try the factor 5 first by plugging it in the equation:

5^3 + 40(5^2) + 175(5) - 2000 = 0

Lucky break! No need to find the other roots because they will be negative, and you can't have a negative value for a pool depth.

So, depth = 5 ft

width = 5 + 5 = 10 ft

length = 5 + 35 = 40 ft
