It looks like y=x(x-2)(x+1) because of where the graph intersects the x-axis.

This is the same as y = x³-x²-2x

ANS: x(x+1)(x-2)

What are the x intercepts that lies on the x - axis? We can see that there is a -1, 0, 2

Given this x intercepts we can easily get the equation
x(x+1)(x-2)

A computer monitor is listed as being 17 inches. This is the diagonal across the screen. If the screen measures 10 inches in hei

Aneli [31]

diagonal = sqrt(l^ + w^2)

17 = sqrt(10^2 + x^2)

17^2 = 10^2 + x^2

289 = 100 + x^2

189 = x^2

x = sqrt(189) = 13.747

X = 13.75

Nathan just bought a car. He models the value, V, in dollars, of the car after t years as V(t)=21,000(0.861)^t. Based on this mo

Snezhnost [94]

Answer:

Value of the car is decreasing by 13.9% each year.

Step-by-step explanation:

This equation tells us V(t) is the value of the car after a certain time in years, $21,000 is the initial value of the car. What we need to focus on is on the 0.861 part of this equation. This means that the price of the car is worth 0.861 or 86.1% of what it was worth the year prior, this means that the price of the car is decreasing over time. By how much is it decreasing? Well if we consider 1 to mean 100% (since 100 / 100 =1) then we have 100%-86.1%=13.9%. This means that the value of the car is decreasing 13.9% each year.

On a 50-question test, a student answered 5 questions incorrectly. What percent did the student answer correctly? A. 45% B. 90%

nadya68 [22]

Hey there,

Pretend that 50 = 100

And that 5 = 10.

I did a 100 test unit test, and I got 10% wrong.

If you think about this, the answer would be 90%

So, it's the same in this case,

50 in half of 100

5 is half of 10.

So . . .

This would mean that your correct answer would be 90% because 5 in this case is to be considered to be 10.

Your correct answer is . . . .

$\boxed{\boxed{90 \ would \ be \ your \ correct \ answer }}$

Hope this helps
