Y = 5/2x - 5

y = mx + b

you know this because the line is inclining five units and shifting 2 units to the right

b = -5 because that’s where the line hits the y-axis

hope that helped

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>

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

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

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

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

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

$=0-0+0+52.5$

$\bold{y=52.5}$

The sun is about 93x the sixth power of then miles from earth what is this distance written as a whole number?

AnnyKZ [126]

The number is written as

$93 \times 10^6$

To evaluate the power of ten, just remember that 10 to the power of n is a one followed by n zeroes, so ten to the sixth power is a one followed by six zeroes:

$10^6=1000000$

So, the number is

$93 \times 1000000$

When you multiply a number by a power of ten, you simply add the same number of zeroes after the number. So, in this case, you only need to add six zeroes after 93:

$93 \times 1000000 = 93000000$

which is 93 millions.

Tyler is building a fish tank in the shape of a sphere that has a diameter of 20 inches. Based on Tyler's research, it is recomm

nikklg [1K]

Answer: 6 fishes

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a sphere = 4/3 x π x (diameter/2)^3

Replacing with the values given:

V = 4/3 x π x (20/2)^3

v = 4/3 x π x (10)^3 = 4,188.79 in3

Finally, we have to divide the volume of the fish tank by the volume that each goldfish needs.

4,188-79 / 693 = 6.04 = 6 fishes

Feel free to ask for more if needed or if you did not understand something.
