What is the slope of this line ?

lidiya [134]

Answer:

The slope of this line is 7/4 or 1.74 in decimal form.

m = 7/4 OR m = 1.75

Step-by-step explanation:

slope = y^2 - y^1 / x^2 - x^1

Let's pick any two points from the graph: (-1, -3) and (3, 4)

m = y^2 - y^1 / x^2 - x^1

m = 4 - (-3) / 3 - (-1)

m = 4 + 3 / 3 + 1

m = 7/4

m = 1.75

What is the radius of a sphere if its surface area is 2,122.64 square inches? (Use 3.14 for π.) 11 in. 13 in. 121 in. 169 in.

crimeas [40]

To solve this, we are going to use the surface are of a sphere formula: $A=4 \pi r^2$
where
$A$ is the surface area of the sphere
$r$ is the radius of the sphere

We know for our problem that $A=2122.64$ and $\pi =3.14$ , so lets replace those vales in our formula:
$A=4 \pi r^2$
$2122.64=4(3.14)r^2$
$2122.64=12.56r^2$
Now, we just need to solve our equation for $r$ :
$\frac{2122.64}{12.56} =r^2$
$r^2=\frac{2122.64}{12.56}$
$r^2=169$
$r=+or- \sqrt{169}$
$r=13$ or $r=13$
Since the radius of a sphere cannot be a negative number, $r=13$ .

We can conclude that the radius of a sphere with surface area 2,122.64 $in^2$ is 13 in.
