Answer:
(x+3)²+(y-4)²=36.
Step-by-step explanation:
For this, we need to use the equation of a circle which is:
(x-h)²+(y-k)²= r²
Simply substitute the center values for 'h,k', and the radius for 'r'.
This will give you:
(x+3)²+(y-4)²=36.

Answer:
Gas Tanks weighs 20/3kg i.e. 6.67kg while Sacks weighs 40kg
Step-by-step explanation:
Total weight = 210kg
Balloon Weight = 163.33kg
Remaining Weight = 210 - (490/3)
=46.67kg
Let the weight of Gas tank = g
Let the weight of Sacks = s
This remaining weight comprises of weight of Sacks and Gas Tanks.
i.e.
g+s = 140/3 = 46.67
As given that,
So,
s=40kg
As provided
Now to find g:
g+s = 140/3
Answer:
the height of the tree to the nearest tenth of a meter is 13.8 meters
Step-by-step explanation:
The computation of the height of the tree is shown below:
Given that
Distance from the tree is 10 meters
And, the angle of elevation of the tree is 54 degrees
Now here we used the trigonometry
So, the height is
= 10 × 1.38
= 13.8 meters
hence, the height of the tree to the nearest tenth of a meter is 13.8 meters
ANSWER: The statistical procedure that should be performed is REGRESSION.
Step-by-step explanation: Regression is a statistical procedure that is used to estimate the relationship between an independent variable and a dependent variable using their mean values.
The independent variable in this case is the hours each student spend in studying, while the dependent variable is the students grade.
Since the researcher wants to determine if the hours a student spend in studying maths and science has any significant effect on their grades. The researcher should use regression, because it will show if the two variables are related and how it relates, by showing how far the points are from the trend lines of the graph.
