Answer:
Step-by-step explanation:
To find:
The value of 
= ?
Solution:
Kindly consider the equilateral 
as attached in the answer area.
Let the side of triangle = 
units
Let us draw the perpendicular from vertex A to side BC.
It will divide the side BC in two equal parts.
i.e. BD = DC = 
Using Pythagorean Theorem in 
:
Side AD = 
Using Trigonometric ratio:
Putting the values of AD and BD:
Answer:
4.2 is: 1.) between 4 and 5 closer to 4
7/8 is: 3.) between 0 and 1 closer to 1
-9/5 is: 2.) between -1 and -2, closer to -2
Answer:
<h3>n = -8</h3>
Step-by-step explanation:
For two lines to be parallel, they must have the same slope
Get the slope of each line
For L1;
m1 = -2-4/1-n
m1 = -6/1-n
For L2;
m2 = 5-3/1-4
m2 = 2/-3
m2 = -2/3
Since they have the same slope, m1 = m2
-6/1-n = -2/3
6/1-n = 2/3
Cross multiply
2(1-n) = 6(3)
2-2n = 18
-2n = 18 - 2
-2n = 16
n = -16/2
n = -8
Hence the value of n is -8
Answer:
The corresponding point for the function f(x)+4 would be (4,-3)
Step-by-step explanation:
Since the transformation is outside of the parenthesis, that means the y-coordinate is only affected.
add 4 to -7 and you get -3
Answer:
Use distributive property to get rid of the parentheses.
Step-by-step explanation:
9+7(x-1)=4x+14
Use the order the operations (PEMDAS)
Parentheses
Exponents
Multiply
Divide
Add
Subtract
First you need to get rid of the parentheses by using distributive property.
9+7x-7=4x+14
