Explanation:
Given the two baselengths, and the perpendicular height of the trapezoid, you can actually find the perimeter through the pythangorean theorem because the perpendicular height or height that forms a right or 90 degree angle makes a right triangle(2 be exact because this is an isoceles trapezoid which has two adjacent right triangles).
This is true of the trapezoid is icosceles.
Answer:
You cannot find the perimeter with numbers given.
Step-by-step explanation:
The top length, base length, and height are not sufficient to determine the perimeter of a trapezoid

Mrs. Williamson had 18 students in her homeroom at the beginning of the school year and 24 students at the end of the year. What was the approximate percent increase in the number of students in Mrs. Williamson’s homeroom?
Answers
Answer:
The approximate % increase was around 33%
Step-by-step explanation:
Divide 24 by 18 and you convert the decimal into a percent which is just multiplying it by 100
There was an increase of 33.33 percent in Miss Williamson‘s homeroom
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then multiply it with b so that we collect b items per 100 items.
Since Percentage increase in the number of students can be calculated as;
=((Final number-Initial number)/Initial Number)×100
where the Initial number of students=18 students
Final number of students=24 students
Now substituting;
((24-18)/18)×100
=(6/18)×100
=33.33% increase
Hence, there was an increase of 33.33%.

let the function be f defined by f (x) = 12 - 5x
(a) is it true that f (0) = 0 ? explain why or why not.
(b) evaluate f (-1)
(c) what value of a will make the equation f (a) = 6 true?
Answers
Answer
a)no
Step-by-step explanation:
a)12-5(0)
=12 not 0
b)12-5(-1)
=17
c)12-5x=6
-5x=6-12
x=1.2
hope it helps:)
Evaluating the function, it is found that:
a) No, since [tex]f(0) = 12[/tex], as when we replace x by 0, the value of y is 12.
b) [tex]f(-1) = 17[/tex]
c) [tex]a = \frac{6}{5}[/tex]
The function given is:
[tex]f(x) = 12 - 5x[/tex]
Item a:
f(0) is given by:
[tex]f(0) = 12 - 5(0) = 12[/tex]
So it is not true, since [tex]f(0) = 12[/tex].
Item b:
[tex]f(-1) = 12 - 5(-1) = 12 + 5 = 17[/tex]
Item c:
This is the value of x when f(x) = 6, thus:
[tex]12 - 5x = 6[/tex]
[tex]5x = 6[/tex]
[tex]x = \frac{6}{5}[/tex]
Thus:
[tex]a = \frac{6}{5}[/tex]

PLEASE HELP 15 POINTS 1. An architect is drawing a sketch for a new building. He uses graphs of lines on a coordinate plane to sketch out
his ideas. The architect has plotted the graph of the line 4x + 16y = 8.
What is the equation of the line he has graphed in slope-intercept form? (Reduce all fractions)
2
Write the equation in slope-intercept form perpendicular to the original line that goes through the point
(-6, -19)
3
Write the equation in slope-intercept form parallel to the original line that goes through the point (-8,6).
Answers
Answer:
1) [tex]y=-\frac{1}{4}x+\frac{1}{2}[/tex]
2) [tex]y=4x+5[/tex]
3) [tex]y=-\frac{1}{4}x+4[/tex]
Step-by-step explanation:
Question 1:
All you have to do is solve for y to get the slope intercept form.
[tex]4x+16y=8\\16y=-4x+8\\y=-\frac{1}{4}x+\frac{1}{2}[/tex]
So the equation is [tex]y=-\frac{1}{4}x+\frac{1}{2}[/tex]
Question 2:
Now for this one you have to find the line perpendicular to the previous equation.
Finding the slope:
So first we need to find the slope and usually the slope of a perpendicular line is the opposite and the reciprocal to the original equation. So instead of [tex]-\frac{1}{4}[/tex] it will be [tex]\frac{4}{1}[/tex] or even easier to manage [tex]4[/tex].
Finding the y-intercept:
For the y-intercept we need to plug in what we know into this formula....[tex]y=mx+b[/tex]
We know the slope is [tex]4[/tex] and we could use the ordered pair that they provided us with [tex](-6,-19)[/tex]. The -6 is the x and the -19 will be the y. Now let's plug in and solve.
[tex]y=mx+b\\-19=4(-6)+b\\-19=-24+b\\b=5[/tex]
Writing the equation:
Now we know all the information needed to write the equation.
[tex]y=mx+b\\m=4\\b=5[/tex]
Now we just fill it in the formula...
[tex]y=4x+5[/tex]
Question 3:
For a parallel equation the slope will be the same in order for them to be parallel to each other.
Finding the y-intercept:
For the y-intercept we need to plug in what we know into this formula....[tex]y=mx+b[/tex]
We know the slope is [tex]-\frac{1}{4}[/tex] and we could use the ordered pair that they provided us with [tex](-8,6)[/tex]. The -8 is the x and the 6 will be the y. Now let's plug in and solve.
[tex]y=mx+b\\6=-\frac{1}{4}(-8)+b\\6=2+b\\b=4[/tex]
Writing the equation:
Now we know all the information needed to write the equation.
[tex]m=-\frac{1}{4}\\b=4[/tex]
Now we just fill it in the formula...
[tex]y=-\frac{1}{4}x+4[/tex]

the greatest common divisor of any two integers which are coprime is 1 so
gcd(2^57,885,161 - 1, 2^43,112,609 - 1) =1
tan(π/4) = 1

Answers
Answer:
y = x + 3
Step-by-step explanation:
To know which of the equations represent the relationship between x and y, you need to substitute the x and y values into the equation. If when the equation is solved, the left-hand and right-hand side of the equation equal each other and hence the equation is true, then the equation must be correct in expressing the relationship between the x and y values. If not, then it is not correct.
As this question is only dealing with linear equations, we know that the gradient of the line is constant and hence the rate of change in x and y values is constant. Therefore, we can choose to substitute any of the given combinations of x and y values into the equation to obtain the correct equation. As it is easier to use smaller numbers for smaller calculations, we'll use the first combination of x = 1 and y = 4 .
Equation No. 1 : y = 3x + 1 where x = 1 , y = 4 and x = 2 , y = 5
( 4 ) = 3 ( 1 ) + 1
4 = 4
However, as this equation has a constant not equal to 1 in front of the x variable and hence a different gradient to the other equations, we will substitute the second combination of x and y values.
( 5 ) = 3 ( 2 ) + 1
5 = 6
Therefore, equation is false / incorrect.
Equation No. 2 : y = x + 1 where x = 1 , y = 4
( 4 ) = ( 1 ) + 1
4 = 2
Therefore, equation is false / incorrect.
Equation No. 3 : y = x + 3 where x = 1 , y = 4
( 4 ) = ( 1 ) + 3
4 = 4
Therefore, equation is true / correct.
Equation No. 4 : y = x - 3 where x = 1 , y = 4
( 4 ) = ( 1 ) - 3
4 = - 2
Therefore, equation is false / incorrect.

Kathy Is 12 years old and Ben is 16 years old. How many years ago was Ben three times Older than Kathy?
Answers
Setting up an equation to represent the scenario, we can conclude that Ben was 3 times older than Kathy 10 years ago.
Present age :
Kathy, k = 12 Ben, b = 16Serting up the equation thus :
Let the number of years = x
16 - x = 3(12 - x)
16 - x = 36 - 3x
Collect like terms
-x + 3x = 36 - 16
2x = 20
x = 10
Hence, Ben was 3 tines older than Kathy 10 years ago.
