Answer:
Option A is correct
reflection across the x-axis
Step-by-step explanation:
The rule for reflection across x-axis is given by:
As per the statement:
The coordinate of triangle ABC are:
A(−4,−3) , B(−7,1) and C(−1,−1).
The coordinate of triangle A'B'C' are:
From the given diagram we have;
A'(-4, 3), B'(-7, -1) and C'(-1, 1)
Apply the rule of reflection across x-axis on ABC we have;
Therefore, the reflection results in the transformation of △ABC to △A'B'C' is, reflection across the x-axis
Answer:
<h3>Option d) 4x + 2y = 10 and 8x = 16 is correct</h3><h3>Therefore 4x + 2y = 10 and 8x = 16 equations have equivalent solution (2,1) is same as the solution of given linear system of equations</h3>Step-by-step explanation:
Given equations are
First find the solution to the given system of equations by elimination method
Multiply the equation (2) into 2 we get
Now adding the equations (1) and ( 3) we get
_______________
x=2
Therefore the value of x is 2
Substitute the value of x in equation (1) we get
y=1
Therefore the value of y is 1
Therefore the solution to the given system of equations is (2,1)
<h3>Now to find the equivalent system of equations have same solution (2,1)</h3>Verify the equations and 8x = 16
From 8x=16
x=2
Therefore the value of x is 2
Substitute x=2 in equation (4) we get
4(2)+2y=10
8+2y=10
2y=10-8
2y=2
y=1
Therefore the value of y is 1
Therefore the solution is (2,1)
<h3>Therefore option d) 4x + 2y = 10 and 8x = 16 equations have equivalent solution (2,1) is same as the solution of given linear system of equations </h3>Answer:
The approximate volume is
Step-by-step explanation:
we know that
The exact volume of the cylinder is
so
To find the approximate volume of the cylinder, substitute the term by the approximate value of
and then multiply
so
