If you are using a calculator, simply enter 30÷80×100 which will give you 37.5 as the answer.
In the given interval 1 < x < 6, the function is decreasing.
As seen from the graph, the value of function is lower at every next value of x than its previous value. For example value function is lower at x = 2 as compared to x = 1. Likewise the value is lower at x = 3 than x = 1 and x = 2 and this continues till x= 6. Therefore, the function is decreasing.
Another way to look at the problem is see the slope of the function. The line is constantly falling down, which means it is a decreasing function.
Hi
two lines are parallel only if they have the same slope.
So : 3x+4y = 12
4y = 12 -3x
y = 12/4 - 3x/4
y = 3 - 3/4 X
y = -3/4 X +3
Slope is -3/4
and 6x+2y = 6
2y = 6 -6x
y = 6/2 - 6x/2
y = 3 - 3X
y = -3X +3
Slope is = -3
As -3/4 ≠ -3 then the two lines are not parallel.
Answer: 55°
Step by step:
80 + x = 180
x = 100
Because the bottom of the figure is a line which equals 180°, so you would subtract 80 from 180 to get the angle on the other side of the line dividing the triangles.
Then, you would use the triangle sum theory which states that the angles of a triangle equals to 180.
100 + 25 + x = 180
125 + x = 180
x = 55°
So angle CBD = 55°
Answer:
Approximately 360.3
Step-by-step explanation:
△ABC, AB = BC and CH is an altitude.
Note in isosceles triangle the two base angle are equal.
And two sides are equal.
CH = 84 cm and m∠HBC = m∠BAC +m∠BCH
So yhe base angle = 50°
The length of tthe hypotenuse , lets cal it x
Sin 50 = 84/x
X = 84/sin 50
109.65 = x
For the The base
109.65²-84²=b²/4
141 = b
Perimeter = 2*109.65 + 141
Perimeter = 360.3
Approximately 360
