Find the area of the square, the triangle and the circle at the top....but remember to take half of the area for the circle since its not a whole circle.

Start by finding the area of the semicircle, it should be (pi*6^2)/2.  Then find the area of the rectangle, it should be 12*7.  Then find the base of the triangle, it should be 15 squared minus 12 squared, then unsquare the answer to get the base.  The area of a triangle is Base*height/2.  Then add them all together, its long but I hope it helps.

Going into the final exam, which will count as two tests, Brooke has test scores of 75, 82, 70, 65, and 90. What score does Broo
dusya [7]
Brooke needs to get a 98 on the final to get an average of 80.
So you know that the total of the five given score is 382 by adding all the scores.
Now you multiply the average, 80 by 6 for the total of six tests including the final which is 480
Then you subtract 480-382 to find your answer.

Which statement is true of the function f(x) = Negative RootIndex 3 StartRoot x EndRoot? Select three options.
ycow [4]

Answer:

Options (2), (3) and (4) are correct.

Step-by-step explanation:

The given function is f(x) = -\sqrt[3]{x}

1). First derivative of the function = f'(x) = \frac{d}{dx}(-\sqrt[3]{x} )

  f'(x) = -\frac{1}{3}(x)^{-\frac{2}{3}}

  Since derivative is negative, function will be decreasing everywhere.

  Therefore, Option (1) is incorrect.

2). Since value of the function is true for every value of all real values of x.

  Domain of the function is (-∞, ∞).

  Therefore, Option (2) is correct.

3). For the given domain, range of the function will be all real values of y Or (-∞, ∞)

  Therefore, Option (3) is correct.

4). Function 'f' when reflected across x axis, equation of the reflected function will be g(x) = \sqrt[3]{x}.

 Therefore, Option (4) is correct.

5). For a point (3, -27),

  -27 = -\sqrt[3]{3}

  Therefore, Option (5) is incorrect.
