Answer:
y = x^2 + 6
Step-by-step explanation:
If I am guessing the exponent correctly for your equation and it really is :
(x+5)² + (y-7)² = 36
then your answer would be answer choice A(6)
Answer: -0.64
Step-by-step explanation:
We know that the coefficient of determination in a simple linear regression model is denoted by 
, which gives the proportion of the variance in the dependent variable that is predictable from the independent variable.
Given, the coefficient of determination in a simple linear regression model is 64%.
i.e.
As there is negative relation between the dependent and independent variables.
Then, the correlation coefficient = -0.64
Rectangle on top is 4 units by 8 units = 32 units squared.
The half circle has radius 2, so the area is pi*2^2/2 = 4pi /2 = 2pi
Total area is 32+2pi or approx 38.28 square units, answer C
Draw a vector triangle. When you draw the horizontal and vertical components, you end up with a right triangle. The magnitude of the vector is equal to the hypotenuse of the triangle so you can use the Pythagorean theorem to calculate it. Rearrange the Pythagorean theorem to calculate the magnitude.
