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>

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

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

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

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

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

$=0-0+0+52.5$

$\bold{y=52.5}$

What is the distance in meter of an object that has an angular diameter of 30 arcseconds and a linear diameter of 10 cm?

Leya [2.2K]

Answer:

Distance of object = 0.0144 meter

Step-by-step explanation:

Given:

Angular diameter = 30 arcseconds = 30[100 / 3600]

Length of diameter = 10 cm

Find:

Distance of object

Computation:

Distance of object = [(2)(a)][TanФ / 2]

Distance of object = [(2)(10)][Tan(300 / 7200]

Distance of object = [20][Tan 0.04167]

Distance of object = [20][0.00072]]

Distance of object = 0.0144 meter

About how many miles are in 16,300 ft

Studentka2010 [4]

About 3, because there are 5280 feet in a mile, so 2 miles would be 10560, and 3 would be 15840, and that is the closest you will get, because the 4th miles would be 21120.

Find the quotient. If possible, rename the quotient as a mixed number or a whole number. Write your answer in simplest form, usi

marshall27 [118]

<h2>Answer:</h2>

3/5 divided by 1/2 equals 6/5 or 1 and 1/5!

(My method- Keep 3/5, change the division sign to a multiplication sign, and flip 1/2 to 2/1. Multiply strait across and you get 6/5! 5 can go into 1 one time and that leaves 1/5! So your answer is 1 and 1/5
