Answer:
2
Step-by-step explanation:
The best mechanical advantage you can get is obtained by pushing the door at its edge. If the door's center of mass is halfway from the hinge to the edge, then the advantage you get (in terms of force reduction) is ...
1/(1/2) = 2
The answer is c (x+21) and (x-2) you have to find two numbers that multiply yo give you -42 and add to give you 19
x = 60
x and 60 are alternate angles and congruent, thus
x = 60
Answer:
first side=40
second side=20
third side=22
Step-by-step explanation:
LET THE SIDES OF THE TRIANGLES BE y
Perimeter=82
first side=2 x y = 2y
second side=y
third side=2 +y
2y + y + 2 + y=82
4y+2=82
4y= 82-2
4y=80
y=80/4
y=20
first side=2y=2(20)=40
second side=y=20
third side= 2 + y= 2 + 20 = 22
The slope of the line that is perpendicular to 6x + 2y = -32 is: 1/3.
<h3>What is the Slope of Perpendicular Lines?</h3>
The slope of two lines that are perpendicular to each other will always have a product that is equal to -1, which means that their slopes are negative reciprocals to each other.
Rewrite 6x + 2y = -32 in slope-intercept form:
2y = -6x - 32
2y/2 = -6x/2 - 32/2
y = -3x - 16
The slope is -3. Negative reciprocal of -3 is 1/3.
Therefore, the slope of the perpendicular line would be: 1/3.
