Use the discrimant to determine the nature of the roots
Here's the formula of the discriminant from the equation ax²+bx+c = 0
D = b² - 4ac

If the discriminant is greater than 0, the quadratic equation has 2 real different roots
If the discriminant is equal to 0, the quadratic equation has only one real root.
If the discriminant is less than 0, the quadratic equation doesn't have real root.

Find the discriminant of the equation x² - 2x + 1 = 0
D = b² - 4ac
D = (-2)² - 4(1)(1)
D = 4 - 4
D = 0
The equation has only one real root.

What is 52.0 divided by 21
kicyunya [14]

Going through long division:  We see that 21 goes into 52 twice, with a remainder of 10.  Bringing down the first 0 after '21,' we have '100' to divide by 21; the quotient is 4 and the remainder 16.  Bringing down the 2nd '0' after 21, we now have '160' to divide by 21; the quotient is 7 with a remainder of 13.  So far we have 2.47 as our quotient.  We can continue this process as far as desired.  

Divide 21 into 52 with a calculator to check your work here.

52 divided by 21 is 2.48 after rounding up.

In the point (3,-2), what is<br> the x-value? Which<br> quadrant is this point<br> located?
natali 33 [55]

Answer:

Step-by-step explanation:

The x-value is 3. Coordinate pairs are labeled as (x, y). In this case, the 3 is in the x position.

The point is located in the 4th quadrant. Quadrant labels move counter-clockwise, from 1 to 4 as shown below. In Quadrant 4, the x-value will always be positive, and the y-value will always be negative. This point has a positive x-value and negative y-value, so it is in this quadrant.

PLEASE ANSWER THIS ASAP !!!!
Y_Kistochka [10]

Answer:

y = (1/2)x + 2

Step-by-step explanation:

Find the slope:

Take the rise over run to find this- For every unit it goes up, it goes two units across, so it will be (1/2)

Find the y-intercept:

This is the value of y where the line intersects the y-axis- (0,2), so 2

Substitute these values in for m and b:

y = mx + b

y = (1/2)x + 2

Hope that helps! :)

The attendence at a water park varies directly as the temperature and invesely as the number of days of rain during the month. I
Margarita [4]
Let A be attendance, t the temperature and n the number of days. Then,
A\alpha\frac{t}{n}
A=k\frac{t}{n}
Where k is a constant of proportionality;
If A=3200, T=88 and n=8, then k,
3200=\frac{88k}{8}
3200=11k
k=\frac{3200}{11}
Rewriting the equation and replacing the value of k,
A=\frac{3200t}{11n}
When t=92 and n=12
The A= \frac{3200*92}{11*12}
A=\frac{294400}{132}
A= 2231
