Answer:
The sum of a and b is 12.
Step-by-step explanation:
Try drawing this figure. ABCD would actually be a triangle, rather than the common quadrilateral you would expect - considering there are 4 points plotted. Therefore, we would have to find the distance between respective points ( 0, 1 ) and ( 2, 5 ) / ( 2, 5 ) and ( 7, 0 ) / ( 0, 1 ) and ( 7, 0 ). Let's apply the distance formula and calculate the distance between each point, therefore determining the perimeter.
Distance between points ( 0, 1 ) and ( 2, 5 )
=
=
=
= =
Distance between points ( 2, 5 ) and ( 7, 0 )
=
=
=
= =
And you can calculate the distance between points ( 0, 1 ) and ( 7, 0 ) to be exactly as well. Therefore, you can say that the perimeter of this triangle is = . Note that this is similar to the form we are given. Thus, a = 10, and b = 2 - making it's sum 10 + 2 = 12.
Answer:
Step-by-step explanation:
Yes a function because passes vertical line
Domain: (-3,2)
Range: (-5,4)
Round brackets because the value is not inclluded via a closed circile (we have a open ciricle in the question)
Answer:
A
Step-by-step explanation:
If 1.09 yards is in a meter, then there are 4572 meters in 5000 feet.
A is the correct answer. Hope this helps!
Answer:
Dividing logarithms is not the same as dividing the arguments of a logarithm.
Step-by-step explanation:
1) If we divide two logarithms then we'll find a value. This is not the same as dividing two arguments of the same base logarithms.
For example:
Then
2) Completing the table below to show it clearly:
Answer:
x length
y width
2x=y
2x+2y=42/2
x+y=21 x+y=21
x+2x=21
3x=21/÷3
x=7
7+y=21
y=21-7=14
7×14=98 the area of a rectangle
