How do you graph y=x^2-2x-3

1 answer:

3 0

The graph of the given quadratic equation will be along the y-axis and cuts the intercepts at x (-1,3) points.

<h3>What is a graph? </h3>

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The given quadratic equation is:-

y = x² - 2x - 3

So the value of x will be (-1,3) so the quadratic curve will cut the intercepts at x(-1,3). The graph of the quadratic equation is attached with an answer.

What is the radius of a circle whose equation is x 72 y 102 4

almond37 [142]

The circle of the given radius with equation (x-7)²+(y-10)²=4 is 2 units.

<h3>What do we mean by circles?</h3>

A circle is, in the simplest terms, a circular shape without edges or lines.

Its geometric form is that of a closed curve.

If you track a moving point in a plane while keeping a fixed distance from another point, a circle will have a closed shape.

The English word "circle" derives from the Greek word "kirks," which means "hoop" or "ring."

So, the equation for a circle in its standard form is:

(x - h)² + (y - k)² = r²

Where the radius is r and the centroid is (h, k).

The equation is: (x - 7)² + (y - 10)² = 4

This is rewritten as:

(x - 7)² + (y - 10)² = 2²

When compared to the typical form:

(h, k) = (7, 10)

The circle's radius is 2.

Therefore, the circle of the given radius with equation (x-7)²+(y-10)²=4 is 2 units.

Find the area of the circle with the given diameter. Use 3.14 for π. Round to two decimal places.

harkovskaia [24]

Answer:

14.13 m^2

Step-by-step explanation:

Formula for area:

3.14*r^2

To find the radius(r), you do diameter(d)/2:

9/2=4.5

3.14*4.5^2=14.13 m2

the dog needs a 1/3 of a cup of dog food each day. the bag holds 5 cups of dog food how many days will it last ?

sleet_krkn [62]

Answer:

15 days

Step-by-step explanation:

You have 5 cups of food, and you give him 1/3 a day.

So, <em>5 divided by 1/3</em>, which would get you 15 days. Or you could cross-multiply, meaning you multiply across, but in this case I just made them line up so you can see how to do it. $(food)/(cupsperday) = 5/\frac{1}{3} \\OR\\\frac{(food)}{1}*(cupsperday) = \frac{5}{1} *\frac{3}{1}$

Plz help me with this

stich3 [128]

Answer: $\bold{log\ x=\dfrac{log\ P}{y}}$

<u>Step-by-step explanation:</u>

To eliminate the exponent, apply log to both sides. This allows the exponent to become the coefficient, which can then be divided from both sides.

$x^y=P\\\\log\ x^y=log P\\y\cdot log\ x=log\ P\\\large\boxed{log\ x=\dfrac{log\ P}{y}}$
