Find the y intercept of -2,5 and 3,25

Mathematics
1 answer:
AlexFokin [52]3 years ago
6 0

Answer:

Y-intercept = 13

Step-by-step explanation:

Since, given points are:  

(-2,5) and (3,25)

Now, by slope intercept form:

y= mx + b

Here, m= slope and b= y-intercept

In order to find y-intercept, we must find slope firstly:  

Since,

Slope= m= y2-y1 / x2-x1  

m= 25 - 5 / 3 - (-2)

m= 20 / 5  

m= 4  

Put ‘m’ in slope intercept form:

y= 4x + b  

Substitute either point into above equation:

25= 4(3) +b

25= 12 + b  

25 - 12 = b

or b= 25 - 12

b= 13

Hence, y-intercept is 13.

find the value of solid figure not including hole cutout. Round to two decimal places. Cube figure is 12 feet long with 4 ft cut
Artemon [7]

Answer:

1577.20 ft³

Step-by-step explanation:

Cube of length = 12 ft = a

Hole diameter which is cutout = 4 ft = d

Hole radius which is cutout = 4/2 =2 ft = r

Volume of the cube = a³

⇒Volume of the cube = a×a×a

⇒Volume of the cube = 12×12×12

⇒Volume of the cube = 1728 ft³

The hole cut out will be in the shape of a cylinder

Volume of cylinder = πr²h

⇒Volume of cylinder = π×2²×12

⇒Volume of cylinder = 150.79 ft³

Now volume of the solid figure with hole cut out is

Volume of the cube - Volume of cylinder

=1728 - 150.79

=1577.20 ft³

∴ Volume of solid figure not including hole cutout is 1577.20 ft³
