Answer: 129
Step-by-step explanation: First find the area of the circle. Since we know the area of a circle is πr² (pi multiplied by the radius squared) we can find the area of the half circle. The radius is 5 (because radius is half of the diameter)
Area=3.14(5)²
=3.14(25)
=78.5
But since this is just a half circle, divide this by 2
That will get 39.25
Then add this to the area of the rectangle (L*W) which is 90
That will get about 129
<span>The perimeter of a Triangle is the sum of three sides ; ie assuming k,l,m be the three sides of a triangle means then k+l+m = perimeter of a triangle.
here given that a two sides lengths are 2x+ 2 and 5x-4 ;
and the perimeter length is 16x-6;
let the unknown side be k;
therefore k + 2x+2 + 5x-4 = 16x-6;
resolving k + 7x-2 = 16x-6;
Ans:-
k= 16x-6-7x+2 = 9x-4 ie the
unknown length k is 9x-4</span>
Answer:
B
Step-by-step explanation:
1) Look at the y-intercepts.
The y-intercepts on both equations are the same: 5. That means both equations touch the y-axis at (0,5).
That means we can rule out both A & C.
2) Calculate the rate of change (a.k.a. slope) of f(x).
To do this, we must use two points to find the change of y over the change of x. From the graph, we can use the points (1,2) and (2,-1).
Δy / Δx = 
<em>*The little triangles are the Greek symbol delta. They mean change in...*</em>
That means that the slope of f(x) is -3.
3) Figure out the rate of change (a.k.a. slope) of g(x).
To do this, all we have to do is look at the equation. It is written in y = mx + b format where m = slope and b = y-intercept. That means the slope is 5 as in place of "m" there is a 5.
4) The Answer
The answer is B because 5 [the rate of change for g(x)] is greater than -3 [the rate of change for f(x)].
