Well I don't have a fancy calculator to do your graphing. But number 6 A and B i can help with. A is just a combination of multiplying and adding and subtracting. I got the answers (A) x= -7. (B) x= -6. If you need help with the others if the other person didn't help you let me know. I do online high school so I'm always on...just new to brainly.

To do these problems, plug in a couple of values into the equations, and see the general shape of the graph. To ensure you were right, check them on an online graphing calculator. I highly recommend Desmos Graphing Calculator. Cheers!

Suppose a cylinder has a diameter of 18 feet and a height of h feet. Which equation can be used to find V, the volume of the cyl
IrinaVladis [17]

Answer: option A

Step-by-step explanation:

The volume of a cylinder can be calculated with the formula:

V=\pi r^2h

Where r is the radius and h is the height of the cylinder.

The radius is diameter divided by 2, then:

r=\frac{18ft}{2}\\\\r=9ft

Substitute the radius into the formula. Then you get the following equation that can be used to find V, the volume of the cylinder:

V=\pi (9)^2h

Use the Law of Sines to find the missing angle of the triangle. Find m<b to the nearest tenth.
defon
1. By the Law of Sines, you have:

 SinA/a=SinB/b=SinC/c

  2. You don't need the fraction SinC/c, so you can eliminate it. Then:

 SinA/a=SinB/b

 A=40°
 a=19
 B=m∠b
 b=13

 3. When you substitute this values into SinA/a=SinB/b, you obtain:

 SinA/a=SinB/b
 Sin(40°)/19=SinB/13
 SinB=13xSin(40°)/19
 m∠b=SinB^-1(13xSin(40°)/19)
 m∠b=26.1°

 Therefore, the answer is: 26.1 degrees.

In Minnesota, the state sales tax rate is 6.875%. The price tag on an HDTV gives
torisob [31]

Answer:

1560.38

Step-by-step explanation:

As far as I know, a sales tax is never calculated until money changes hands. So the rebate is the first amount to take place.

1560 - 100 = 1460

Now if the purchaser agrees to this amount and does anything to pay partially or in full, the tax is added.

Total Cost = 1460 * (1.06875)

Total Cost = 1560.38

Edit

You have to be very careful when you use a term like rebate. Rebate is a very special kind of discount. Your purchase has to qualify for a rebate. Apparently this one does. If you are willing to spend 1560 on something, the merchant selling the product offers you a rebate to help you decide.

If the TV cost is 1200 you may not get the rebate.

How many zeros does the function f(x)=3x^12 -17x^8+11x^4-6x+23 have
jeyben [28]

Answer:

12.

Step-by-step explanation:

The number of zeros to an equation is the highest power of the polynomial.

A quadratic equation whose highest degree is 2, has two solutions.

The equation f(x) = $ 3x^{12} - 17x^{8} + 11x^{4} - 6x + 23 $ will have 12 solutions (or zeroes) since the highest degree is 12.
