The vertex for the first one is: (8,-1)
the answer for the second one is: n = -8 + with a - at the bottom square root of 151
the answer for the third question is: n = (-3,-5)
hope i helped please thank, rate, and give me best anyswer if you're on a desktop thank you :)
Answer:
Slope = -6/7
Step-by-step explanation:
You need to use the formula m = y2 - y1 ÷ x2 - x1
The formula means: slope = the y coordinate of point 2 subtract the y coordinate of point 1, divided by the x coordinate of point 2 subtract the x coordinate of point 1
So,
m = 2 - 5 ÷ 3/2 - (-2)
m = -3 ÷ 7/2
m = -6/7
Hope this helps :)
Answer:
He will cover 2,827.433 feet² area of the park with plant food.
Step-by-step explanation:
The diameter of the garden is 60 feet and the radius will be 60 feet/2 = 30 feet.
diameter= 60 feet
radius = diameter/ 2= 60/2= 30 feet
The area of the circle can be found by the formula πr²
Area= πr²=π(30)²
Area = 900π= 2,827.433 feet²
He will cover 2,827.433 feet² area of the park with plant food.
Answer:
Randomization removes lurking variables and biases.
Step-by-step explanation:
In case of an experimental design the groups are divided randomly.
Randomization is important so that there are no bias present in the study and to control any lurking variables. The controlling of the lurking variables provides an accurate result.
Lurking variables have a significant effect on the response variable. Presence of lurking variables can indicate a strong relation between variables or conceal any true relation between the variables.
Randomization thus gets rid of lurking variables and biases.
Also if randomization is used then each of the groups are similar in every way other than the fact that each group is provided with different treatment.
you need to provide more information :/
