A piece of hardware is constructed by drilling a cylindrical hole

Mathematics
1 answer:
abruzzese [7]2 years ago
6 0

The volume of the remaining material once the hole has been drilled to the nearest cubic millimeter is 3010mm³.

<h3>What is a cylinder and a square prism?</h3>

A square prism is simply a 3-dimensional shape figure with square bases and the other four faces are rectangular in shape.

The volume of a square prism is expressed as;

V = a²h

A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.

The volume of a cylinder is expressed as;

V = π × r² × h

Given the data in the question and image below.

For the square prism;

  • Length of sides a = 20mm
  • Height h = 35mm

For the cylinder;

  • Radius r = diameter/2 = 20mm/2 = 10mm
  • Height h = 35mm
  • Constant pi π = 3.14

Now, the volume of tthe remaining material once the hole has been drilled will be;

V = Volume of the square prism - volume of the cylinderical hole

V = ( a² ×  h ) - ( π × r² × h)

V = ( (20mm)² ×  35mm ) - ( 3.14 × (10mm)² × 35mm)

V = 14000mm³ - 10990mm³

V = 3010mm³

Therefore, the volume of the remaining material once the hole has been drilled to the nearest cubic millimeter is 3010mm³.

Which function has a vertex on the y-axis? f(x) = (x – 2)2 f(x) = x(x 2) f(x) = (x – 2)(x 2) f(x) = (x 1)(x – 2)
makvit [3.9K]

The function that has a vertex on the y-axis is f(x) = (x - 2)(x + 2)

<h3>How to determine the function?</h3>

For a function to have its vertex on the y-axis, then the coordinate of the vertex must be:

(h,k) = (0,y)

A quadratic function is represented as:

f(x) = (x - h)^2 + k

So, we have:

f(x) = (x - 0)^2 + k

Evaluate

f(x) = x^2 + k

From the list of options, we have:

f(x) = (x - 2)(x + 2)

Expand

f(x) = x^2 - 4

Hence, the function that has a vertex on the y-axis is f(x) = (x - 2)(x + 2)

Will mark brainliest!! solve &amp; simplify the following equation: 2x²-7x=4​
Goryan [66]

Answer:

x=  −1 /2   or x=4

Step-by-step explanation:

This is ALGEBRA, equations, factoring and zero property. ok.. let's solve this step-by-step

2x^2−7x=4

<u>Step 1: Subtract 4 from both sides. </u>

2x^2−7x<u>−4 </u>=4 <u>−4 </u>

2x^2−7x−4=0

<u>Step 2: Factor left side of equation. </u>

(2x+1)(x−4)=0

<u>Step 3: Set factors equal to 0. </u>

2x+1=0 or x−4=0

x=  −1 /2   or x=4

(BTW, there are supposed to be two answers, it's factoring)

Sorry if the format is not clear, but I hope this helped (really feel you, algebra can be brain-striking)!! Please leave a comment, rating and/or mark as the brainliest-whichever you think I deserve! Thank You :)

Answer:

a) 14

b) 514

Step-by-step explanation:

use number line for b

514 is 14 away from 500

485 is 15 away from 500

so 514 is closer to 500
