Find the zero of the function p(x) = 1/4x-3

Mathematics
1 answer:
harkovskaia [24]2 years ago
3 0

Answer:

x = 12

Step-by-step explanation:

Given

p(x) = \frac{1}{4} x - 3

To find the zero let p(x) = 0, that is

\frac{1}{4} x - 3 = 0 ( add 3 to both sides )

\frac{1}{4} x = 3 ( multiply both sides by 4 )

x = 12 ← zero of p(x)

How many cubes with side lengths of
Bad White [126]

question:

How many cubes with side lengths of \dfrac12 \text{ cm} 2 1 ​ cmstart fraction, 1, divided by, 2, end fraction, start text, space, c, m, end text does it take to fill the prism? ​

Step-by-step explanation:

81 cubes are needed to fill the prism

Step-by-step explanation:

Volume of prism = 3 cubic units

Side lengths of cube = 1/3

Therefore the volume of the cube is,

V = a³   (a = side of the cube)

V = 1/3 × 1/3 × 1/3

= ( 1/3 )³  

= 1/27 cubic units

To find the number of cubes needed to fill the prism, we need to divide the volume of cube by volume of the prism.

Number of cubes to fill the prism= Volume of prism / Volume of cube

= 3÷1/27

=3×27/1

= 81

Therefore, 81 cubes are needed to fill the prism

If a table seats 7, what is the least number of tables needed to seat 155 people
Fynjy0 [20]

23 is the minimum because 155 does not go into evenly and you have to have enough room for everybody, and make sure not to leave anybody out. 155 divided by 7 is 22.1428571429, you have to round it up to 23 so that everybody has a seat. Hope it helps!!
