Answer:
A = 1/2(y2-y1) (x3-x1)
A = 21 units^2
Step-by-step explanation:
The area of a triangle is 1/2 bh
Using the left side as the base b= 6 units
This is found by taking (y2-y1)
The height is 7 units, counting from the left side to x3
This is found by taking (x3-x1)
A = 1/2(y2-y1) (x3-x1)
A = 1/2 (6*7)
A = 1/2 *42
A = 21 units^2
Answer:
From -2<x<-1, the function F(X) is increasing. (B)
Really, it increases all from around -2.5<x<0.5
C is also the second answer, as it increases til around 2.5
It is decreasing from -4<x<-3. But increases right after. It then starts to slow down around x = 1 and go down again.
Which means (B) is your answer.
If you want to get fancy, its a polynomial and if you take the derivative for instantaneous rate, you will see f prime is increasing if you make an example function.
The answer to your question is 8, because you replace z with 2
Answer:
n = 1
Step-by-step explanation:
Due to it being compounded semiannually, the total amount after n years should be 2000[1+(.086/2)]^2n = 3178. (A = p(1+r/n)^nt)
Hence, solving this equation:
(1+0.43)^2n = 3178/2000
1.43^2n = 1.589
2n = 2
n = 1
Length is equal to 4 and width is equal to 5.
You can just divide each by 2.
