Write the equation of a line that is perpendicular to x = -1 and that passes through the Point (8, -4).
Answers
Answer:
y = - 4
Step-by-step explanation:
x = - 1 is the equation of a vertical line parallel to the y- axis
The equation of a line perpendicular to it will therefore be a horizontal line parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (8, - 4 ) with y- coordinate - 4 , then
y = - 4 ← equation of perpendicular line

Answers
Step-by-step explanation:
1. Angle 5 = 120 degree
Angle 5 = Angle 6 ( alternate exterior angles are equal )
Therfore, Angle 6 = 120 degree
Angle 6 = Angle 4 ( Vertically opposite angles are equal )
Therfore, Angle 4 = 120 degree
Angle 4 = 5x
120 = 5x
120/5 = x
40 = x
Therefore x = 40 degree.
2. Angle 1 = 100 degree
Angle 1 = Angle 7 ( vertically opposite angles are equal )
Therefore, Angle 7 = 100 degree
Angle 7 = 10x
100 = 10x
100/10 = x
10 = x
Therefore x = 10 degree

ABCD is a square with an area of 49 cm2, and BE = 4.95 cm. Point E is the midpoint of 2 diagonal lines crossed inside the square.
Answers
Answer:
I suppose we want to find the side length of the square.
We know that:
The area of the square is 49cm^2
The distance between one of the vertices of the square and the middle of the square is:
BE = 4.95cm
Now let's remember some things.
For a square of side length L, the area is:
A = L^2
and the diagonal length is:
D = √(2)*L
In this case, we know that half of the diagonal is equal to:
BE = 4.95 cm
Then the diagonal is:
D = 2*BE = 2*4.95cm = 9.9cm
And for the diagonal formula, we have:
D = 9.9cm = √(2)*L
Then the side length is:
L = 9.9cm/√(2) = 7cm
And if we check the area of this square, is:
A = L^2 = (7cm)^2 = 49cm^2
So it checks.
Then we can conclude that the sidelength of the square is 7cm, which means that:
AB = 7cm
BC = 7cm
CD = 7cm
DA = 7cm

Third option : 9^10 / 9^2
Step-by-step explanation:
9^2 . 9^6
Formula / Identity : -
a^m . a^n = a^( m + n )
Here,
a = 9
m = 2
n = 6
9^2 . 9^6
= 9^( 2 + 6 )
=9^8
9^10 / 9^2
Formula / Identity : -
a^m / a^n = a^( m - n )
Here,
a = 9
m = 10
n = 2
9^10 / 9^2
= 9^( 10 - 2 )
= 9^8
Therefore,
9^10 / 9^2 is equivalent to 9^2 . 9^6.

The sum of two circles is 80 pi square meters. Find the length of the radius if one of them is twice as long as the other
Answers
Answer:
Length of Radius of large circle= 8
Lenght radius of first circle= 2
Step-by-step explanation:
THIS IS THE COMPLETE QUESTION
The sum of the areas of two circles is 80π square meters. Find the length of a radius of each circle if one of them is twice as long as the other.
What is the radius of the larger circle?
Area of a circle can be calculated by Below formula
A = πr^2............eqn(1)
Let ( X) = area of first circle
Y= the area of second circle
Rx= radius of first circle
Ry = radius of second circle
From the question, we know that
[X+ Y] = 80π .......eqn(2)
Substitute the radius formula for the area,
[π(Rx)^2 + π (Ry)^2] = 80π ......eqn(3)
But from the question, Radius of second circle is twice of the second one, then
Ry = 2Rx ..........eqn(4)
If we substitute eqn (4) into eqn(3)
[ π(Rx)^2 + π (2Rx)^2 = 80π
If factorize π out, then cancel it out
π[(Rx)^2 + π (2Rx)^2 = 80π
Then we have
(Rx)^2 + 4(Rx)^2 = 80
5(Rx)^2 = 80
(Rx)^2= 80/5
(Rx)^2= 16
(Rx)= 4
From eqn(4)
Ry = 2Rx
Ry= 2(4)
Ry= 8
Rx= 2 and Ry= 8
Hence, radius of first circle= 2
Lenght Radius of second circle= 8
