Answer:

m = (70-10)/(70-50) = 3 , slope

Step-by-step explanation:

m =(y2-y1)/(x2-x1) = gradient/ slope

choose any points on the graph for each x that corresponds to the y,

say choose, where x =50, y =10 (make this x1 and y1)

second step choose, another points to make Y2 and X2

where x=70, y=70, make these , y2 and x2

thus, m = (70-10)/(70-50) = 3

Write -9.27 as a mixed number

Murljashka [212]

Answer:

The answer is $-9\frac{27}{100}$

Step-by-step explanation:

The answer is in a mixed number form because there is 9 whole numbers and 27 out of 100 left so therefor, the answer is 9 27/100

Find the volume of a right circular cone that has a height of 9.1 cm and a base with a circumference of 13.3 cm. Round your answ

diamong [38]

Answer:

Volume = 42.8 cubic centimeters

Step-by-step explanation:

The volume of right circular cone is:

$V=\frac{1}{3}\pi r^2 h$

Where

r is the radius

h is the height

We are given height of 9.1 cm

h = 9.1

We aren't given radius explicitly, we are given circumference of 13.3, so we need to figure out radius from that. Lets do this:

$C=2\pi r\\13.3=2\pi r\\r=\frac{13.3}{2\pi}\\r=2.12$

So,

r = 2.12

Now, substituting in cone formula, we get the volume to be:

$V=\frac{1}{3}\pi r^2 h\\V=\frac{1}{3}\pi (2.12)^2 (9.1)\\V=42.83$

Rounded to nearest 10th is 1 decimal place, so

Volume = 42.8 cubic centimeters
