Break it into 2 shapes.

A rectangle: 8 x 7 = 56 square inches.

A triangle: 1/2 x 3 x 4 = 6 square inches.


Total: 56 + 6 = 62 square inches.

Answer:

62 in^2

Step-by-step explanation:

We have a rectangle and a triangle.  We can add these shapes together.

The area of the rectangle is length times width

A = 8*7

A rectangle = 56

The area of the triangle is

A = 1/2 *b*h

The base is 7-4 = 3

The height = 12-8 = 4

A = 1/2 * 3*4 = 6

Adding the areas together

A = 56 + 6 = 62 in^2

The general form of the equation of a circle is x2+y2−4x−8y−5=0.
ludmilkaskok [199]
The general equation of a circle is (x-a)^{2} + ( y-b)^{2} =  r^{2} where a and b are the x and y components of the center respectively. 

In order to get into this format, we have to use a method that I'm drawing a blank on the same, my apologies about that.

Anyway, what you want is to first isolate the variable on side so now you have: x^{2} - 4x +  y^{2} - 8y = 5 (you'll see why I rearranged this soon)

Now you have to make it into an equation that can be simplified into the format stated earlier.

So, You have to take the x & y terms (-4x & -8y in this case) divide them each by two, and then square them.

The result of this step is the equation: x^{2} -4x + 4 +  y^{2} - 8y + 16 = 5 + 4 + 16 
Notice the new components that have been added (4 & 16) and how the have been added to both sides. That is an important step.

Now we simplify and get: (x-2)^{2} +  (y-4)^{2}  = 25

So the coordinate of the center is: (2,4) and the radius is 5

Y=x2+3x+1 has how many real roots?
gregori [183]

Answer:

2

Step-by-step explanation:

we will find the discriminant of the equation

d = b^2  - 4ac (here, a = 1 , b = 3 , c = 1. from the general formula: ax^2 + bx + c)

d =  9 - 4

d = 5

since d > 0, the roots are real and different

hence, the both the roots of this equation are equal
