Answer:
Area of parallelogram: 1/2×h×sum of base lengths
Property of parallelogram: 2 parallel sides
Area = 1/2×4×(9+9)
= 36 cm^2
Answer:
Step-by-step explanation:
1.
(-2,0) (0,-7) y2-y1
-----------------
x2-x1
-7-0= -7
0- (-2)= 2 ------>>> -7/2 =m or slope
2.
y= -7/2x+b to find b u plug in one pair of coordinates for example (-2,0)
and use inverse properties to find b
0 = -7/2(-2) + b
14/2 = 7
0= 7+b
-7 -7
-----------
-7=b
3.
y=-7/2x-7
Answer:
x= -4, -3, 3
Step-by-step explanation:
You must factor this equation.
Once you factor, you get (x+4)(x-3)(x+3)
Set this equal to 0 and solve.
You get -4,-3, and 3.
Answer: There are 30 participants are needed for the entire study.
Step-by-step explanation:
Since we have given that
Number of levels of factor A = 2
Number of levels of factor B = 3
Number of participants in each treatment condition = 5
So, the number of participants are needed for the entire study is given by
Hence, there are 30 participants are needed for the entire study.
Answer:
first one: function
second one: not a function
third one: not a function
fourth one: not a function
Step-by-step explanation:
it is never a function if two of the x inputs are the same or if one x input has two y outputs..
