15 less than 3 times a number is 5 more than half of the number.

Answers

Answer 1

Answer:

Mystery Number is 8

Step-by-step explanation:

3x - 15 = 5 + 1/2x

3x - 1/2x = 15 + 5

5/2x = 20

x = 20 / 5/2

x = 20 * 2/5

x = 40 / 5

x = 8

Which statements are correct about the average rate of change for the function f(x) = x2 + 9x + 18 ?

Answers

Answer:

Presumably this is a multiple choice question, and without seeing the potential answers, we can't tell you which ones are correct.

A few things can however be said about this function:

1) It describes a parabola that extends upward infinitely.  We can see this because it's in the classic format ax² + bx + c, and all terms are positive.

2) We can find the x-intercepts by solving for zero.  In this case we can do that by factoring it:

x² + 9x + 18 = 0

x² + 3x + 6x + 18 = 0

x(x + 3) + 6(x + 3) = 0

(x + 6)(x + 3) = 0

So the x intercepts occur at (-6, 0) and (-3, 0)

3) we can find its vertex by taking its derivative and solving for zero:

f'(x) = 2x + 9

0 = 2x + 9

x = -4.5

We can then plug that coordinate into the original function to find the y coordinate:

f(x) = x² + 9x + 18

f(-4.5) = 20.25 - 40.5 + 18

= -2.25

So the vertex is at (-4.5, -2.25)

4) As mentioned, the derivative of f(x) is f'(x) = 2x + 9.  The integral is:

x³ / 3 + 9x² / 2 + 18x + C

The answer is 7/5

Step-by-step explanation:

AD = 2(5/2) = 5

AD is a diameter.

any triangle in a circle with the hypotenuse as the diameter is a right triangle.

Draw a line from point A to point C.

ΔACD is a right triangle.

Solve for ∠CAD:

sin CAD = 3/5 = 0.6000

∠CAD = 36.87°

arc CD = 2 x 36.87°  = 73.74°

arc BC = arc CD = 73.74°

arc DB = 147.48°

∠BAD = 1/2 (147.48°) = 73.74°

draw a line from point D to point B

ΔBAD is a right triangle.

cos 73.74° = AB/5
