Find the length of DE using the distance formula. d =
Answers
Answer:
d = 10units
Step-by-step explanation:
The question is incomplete. Find the complete question attached
The formula for calculating the distance between two points is expressed by the formula;
d = √(x₂-x₁)²+(y₂-y₁)²
Given the coordinate points (-4, 2) and (4, -4)
d = √(4-(-4))²+(-4-2)²
d = √(4+4)²+(-6)²
d = √(8)²+(-6)²
d = √64+36
d = √100
d = 10
Hence the distance between the points DE is 10units

Express 27 4/3 in simplest radical form
Answers
Answer:
3⁴
Step-by-step explanation:
Expressing in the simplest radical form means simplifying a radical so that there are no more square roots, cube roots, fourth roots etc.
It further means removing radicals in the denominator of a fraction.
Given
[tex]27^{4/3}[/tex]
this can be written as

f(x) = x2. What is g(x)?
Answers
Answer: Choice C. g(x) = (3x)^2
To confirm this, plug in x = 1 and you'll find that:
g(x) = (3x)^2
g(1) = (3*1)^2
g(1) = (3)^2
g(1) = 3*3
g(1) = 9
Showing that (1,9) is on the red g(x) curve.

5x-3y=10
Answers
x intercept = 2
the solution is in the pic below
(Sorry if it’s wrong!)
Answer:
strategy: put this equation into slope intercept form y = mx + b
then it is easier to find x and y intercepts
Step-by-step explanation:
5x-3y=10
5x-10=3y
5/3x - 10/3 = y
y = 5/3x - 10/3
when x is zero then y is - 10/3, that's the y intercept
when y is zero then x is 2, that's the x intercept

A classroom is 11 m long, 8 m wide and 5.5 m high Find the sum of the areas of the four walls.
( please show the working out pleaseee)
Answers
Answer:
209 m²
Step-by-step explanation:
The class room has a measurement of 11 m long, 8 m wide and 5.5 m high. Hence the walls of the classroom would be 4, with the following measurements.
Wall 1: 11 m by 5.5 m, Wall 2: 8 m by 5.5 m, Wall 3: 11 m by 5.5 m and Wall 4: 8 m by 5.5 m
The area of wall 1 = 11 m * 5.5 m = 60.5 m²
The area of wall 2 = 8 m * 5.5 m = 44 m²
The area of wall 3 = 11 m * 5.5 m = 60.5 m²
The area of wall 4 = 11 m * 5.5 m = 44 m²
The sum of areas of the fall wall = area of wall 1 + area of wall 2 + area of wall 3 + area of wall 4
The sum of areas of the fall wall = 60.5 + 44 + 60.5 + 44 = 209 m²
Consider the following triangle side lengths and determine if the triangle could exist. Justify your answer. Part A: 21,18,17 Part B: 3,12,8
Answers
Answer:
A yes, B no
Step-by-step explanation:
The triangle inequality states that the sum of any 2 sides of the triangle must be greater than the third side.
A Given 21, 18, 17 , then
21 + 18 = 39 > 17
21 + 17 = 38 > 18
18 + 17 = 35 > 21
Thus the triangle could exist
B Given 3, 12, 8 , then
3 + 12 = 9 > 8
3 + 8 = 11 < 12 ← fails the test
Thus the triangle does not exist
