Triangular a Recallyuldl

PLEASE HELP ALMOST FINISHING ALBERA 1 PUT I NEED YOUR HELP PLEASE I BEG YOU BRAINLEST ANSWER!!!

59 is D
because with the point (-3,7) you substitute it into the equation, making it: 7=4x+b. solve for b. then you have y=4x+19. work out the algebra in the possible choices and whatever equals y=4x+19 will be the answer. in this case, its D.

60 is C
same as above, you do the algebra of the equation. bring the one over after doing distribution with the 4 and voila!

61 is A
a relatively easy one, all you do is the the slope -4 where m goes, and 3 where b goes. y= -4x+3

62 is C.
this one requires more work.
chose one of the points, in this case (2,7) and put them into the equation.
but wait, you need a slope!
you get that use the formula (y2-y1)/(x2-x1) which will be
(7-5)/(2-3) which will be
-2.
now you have y-7= -2(x-2)
voila!

63 is C. y= 1/2x+3

64 is B. (3, -5)

66 is B. negative. the line goes \ ( not / which is positive)

67 would be A. because it is positive and the I and the E are in the right places.

70 is C. 2/3. as before, remember we can but the points into this equation and have (6-4)/(3-0) which = 2/3

71 is D. y= 3x+10

72 is C. a third degree monomial

adell [148]

Answer:

The price per wind chime that will maximize revenue = $ 315

Step-by-step explanation:

Given - A gift shop sells 160 wind chimes per month at $150 each. the owners estimate that for each $15 increase in price, they will sell 5 fewer wind chimes per month.

To find - Find the price per wind chime that will maximize revenue.

Proof -

Given that,

Total Wind chimes selling = 160

Price of each Wind chime = $150

Now,

Given that, for each $15 increase in price, they will sell 5 fewer wind chimes per month.

So,

Let the price = 150 + 15x

So,

Number of wind Chimes sold per month = 160 - 5x

So,

Total Revenue, R = (150 + 15x)(160 - 5x)

= 24000 - 750x + 2400x - 75x²

= 24000 + 1650x - 75x²

⇒R(x) = 24000 + 1650x - 75x²

Differentiate R with respect to x , we get

R'(x) = 1650 - 150x

Now,

For Maximize Revenue, Put R'(x) = 0

⇒1650 - 150x = 0

⇒150x = 1650

⇒x = 1650/150

⇒x = 11

∴ we get

Price per Wind chime = $ 150 + 15(11)

= $ 150 + 165

= $ 315

So,

The price per wind chime that will maximize revenue = $ 315

One leg of a right triangle is 12 inches, and the measure of the angle opposite that leg is $30^\circ$. what is the number of in

Alik [6]

Ok

in a 30-60-90 right triangle, if the leg oposite the 30 degree angle is x then the hypontuse is 2x

if the leg oposite the 30 degree angle is 12 inches then the hypontuse is 12*2 or 24 inches

Using geometry, calculate the volume of the solid under z=64−x2−y2and over the circular disk x2+y2≤64

Anarel [89]

Perhaps you mean to find the volume under $z=\sqrt{64-x^2-y^2}$ ? It seems like you have to rely on calculus otherwise (in the case that you indeed mean $z=64-x^2-y^2$ ).

Assuming this, note that $z=\sqrt{64-x^2-y^2}$ describes the top half of a sphere with radius 8, which means the volume below this surface over the disk $x^2+y^2\le64$ is simply half the volume of the sphere. Thus the volume is

$\dfrac43\pi8^3=\dfrac{2048}3\pi$
