A chair’s regular price is $349. It is on clearance for 30% off, and a costumer uses a 15% of coupon after that. What is the fin
makkiz [27]

Answer:

The final cost is $207.65

Step-by-step explanation:

Regular price of the chair is $349

with 30% off,

(30/100)*$349 = 0.3*$349

= $104.70

actual cost is $349 - $104.70 = $244.30

For a customer using 15% off coupon

15% of actual cost

(15/100)*244.30 = 0.15*244.3

= $36.65

Final cost is $244.30 - $36.65

= $207. 65

One factor of the function f(x) = x ^ 3 - 8x ^ 2 + 17x - 10.5(x - 5) Describe how to find the x-intercepts and the y-intercept o
pickupchik [31]

Answer:

x-intercept(s):  (−1.9900717,  0)

y-intercept(s): (0, 52.5)

Step-by-step explanation:

To find the x-intercept, substitute in  0  for  y  and solve for  x. To find the y-intercept, substitute in  0 for x and solve for y .

f(x)=y

(x)=x

<u>x-intercept</u>

To find the x-intercept(s), substitute in  0  for  y  and solve for  x .

f(x) = x ^ 3 - 8x ^ 2 + 17x - 10.5(x - 5

=\bold{0}=x^3-8x^2+17x-10.5\left(x-5\right)

=0\cdot \:10=x^3\cdot \:10-8x^2\cdot \:10+17x\cdot \:10-10.5\left(x-5\right)\cdot \:10

=0=10x^3-80x^2+170x-105\left(x-5\right)

=0=10x^3-80x^2+65x+525

=10x^3-80x^2+65x+525=0

=10x^2-99.90071\dots x+263.80959\dots \approx \:0

\bold{x\approx \:-1.99007\dots}

<u>y-intercept</u>

f(x) = x ^ 3 - 8x ^ 2 + 17x - 10.5(x - 5

=y=\bold{0}^3-8(\bold{0})^2+17(\bold{0})-10.5\left(\bold{0}-5\right)

=y=0-8\cdot \:0+17\left(0\right)-10.5\left(0-5\right)

=y=0-8\cdot \:0+17\cdot \:0-10.5\left(0-5\right)

=y=0-0+0-\left(-52.5\right)

=0-0+0+52.5

\bold{y=52.5}
