Answer:

(0,-3)

Step-by-step explanation:

( r, theta)

We know that x = r cos theta

x = -3 cos (pi/2)

x = -3 *0 = 0

We also know that y =  r sin theta

y = -3 sin (pi/2)

y    = -3*1 = -3

The  rectangular coordinates are

(0,-3)

NeX [460]

Answer: The correct answer is B; 10,240π in³

Step-by-step explanation: To calculate the volume of a cylinder, the given formular is

Volume = π r² h, where

radius (r) = 16

height (h) = 40

Pi (π) = 3.14

It is important to take note that in questions like these, the value of pi is usually given as 3.14 or 22/7. However, for this particular question, the answer should be expressed in terms of pi, (that is, the answer must include pi). For that reason we shall leave pi as it is, and we shall not use it's value when applying the formular.

Therefore, inserting the values of radius, height and pi into our formular, we now have;

Volume = π r² h

Volume = π x 16² x 40

Volume = π x 256 x 40

Volume = π x 10,240

Therefore the exact volume of the cylinder = 10,240π in³

Given the following values for a quadratic function, which is the graph of the function? (–1, 0), (0, 3), (1, 4), (2, 3), (3, 0)
Firdavs [7]

Answer:

The function of the graph is f(x) = - x² + 2x + 3

Step-by-step explanation:

Using the value of the graph we can say that the the function is negative x² because there are x-intercepts and the y-intercept if above 0.

Using the x-intercepts we can form the function of the graph:

-(x + 1)(x - 3) - we have a negative in front of the two brackets because the function is a negative. Now we multiply out the brackets and the negative at the end:

-(x² - 2x - 3)

- x² + 2x + 3 - So the function of the graph is:

f(x) = - x² + 2x + 3

Find the 10th term <br><br> 3,15,75,375
vova2212 [387]

Answer:

5859375

Step-by-step explanation:

These are the terms of a geometric sequence with n th term

a_{n} = a_{1} r^{n-1}

where r is the common ratio and a_{1} the first term

here r = \frac{375}{75} = \frac{75}{15} = \frac{15}{3} = 5 and a_{1} = 3, hence

a_{10} = 3 × (5)^{9} = 5859375
