Step-by-step explanation:
B) Surface Area
C) Volume
Since we are given that the relationship between x and y
is linear. Therefore this means that the given equation takes the form of:
y = m x + b
where,
b is the y intercept of the equation
m is the slope of the equation
However we should take note that the slope m is directly
proportional to the coefficient of correlation. Since our coefficient of
correlation is negative, this only means that the value of y is decreasing with
increasing x, hence plot of y and x is descending with increasing x.
Furthermore, this also tells that for every 1 unit increase of x, there is a
0.75 units decrease of y.
Answer:
(x + 5)² + (y + 7)² = 288
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
The radius is the distance from the centre (- 5, - 7) to the point on the circle (7, 5)
Use the distance formula to calculate r
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 5, - 7) and (x₂, y₂ ) = (7, 5)
r = 
= 
= 
Hence
(x - (- 5))² + (y - (- 7))² = ()², that is
(x + 5)² + (y + 7)² = 288
The answer is 12.
57 + 39 = 98
98 divided by two is equal to 12.
This can also be shown by multiplication. 12x8=96

Answer:
f^-1(x) = {(-1, 0), (0, 2), (2, 3), (3, 4)}
Step-by-step explanation:
Switch the x and y coordinates of each point.
f(x) = {(0, -1), (2, 0), (3, 2), (4, 3)}
Answer:
f^-1(x) = {(-1, 0), (0, 2), (2, 3), (3, 4)}
