Find the measures of the angles given

dexar [7]

Answer:

BCD = 60

ABD - 90

Step-by-step explanation:

BCD)

BC and CD are the same length on in the circle, they are the radius. Therefor, all angles will be the same at 60

ABD)

All angles together are 180

You know 2 Angles, A at 30 and D at 60

180 - 30 - 60 = Angle B

90 = Angle B

Which are true?

Tanzania [10]

Answers:

True. All states have a different approach to collecting revenue, which is money they spend on government programs. Most states have income taxes, but a state like Florida doesn't have income taxes. Instead they rely on sales taxes and property taxes. The general rule is that if one tax is missing, then chances are the other tax rates are higher to make up the lack of funds (that the missing taxes would provide).
False. States vary in sales tax rates. For instance, Alabama's sales tax is 4% while Arkansas is 6.5%
True. You can do an online search of "states without sales tax" to find sources to help confirm this. Keep in mind that while the state overall does not impose sales tax, this does not mean the city and/or county governments won't impose sales tax. Unfortunately it's hard to escape taxes and sales tax is just one of those inevitable things.
True. As mentioned in problem 3, local governments (city and/or county) tend to impose taxes of their own on top of state sales taxes. Sales taxes fund state programs while local taxes fund local programs. Though some local government programs will use state or federal dollars.

What it the x and y intercept of y=2x^2+3x+1

castortr0y [4]

What you have here is a quadratic polynomial.

The form is: ax^2 + bx + c

C is ALWAYS the y-intercept in non-linear polynomials. So we immediately know the y-intercept to be 1.

For the X-intercept(s), we can solve in a few ways, but let's use the quadratic formula.

The quadratic formula states that y=-b+-((sqrt(b^2-4ac) / 2a).

A = 2

B = 3

C = 1

Plug in your information,

$\frac{-3 \frac{+}{-} \sqrt{3^2 - 4(2)(1)} }{2(2)} \\\sqrt{9 - 8}\\ \sqrt{1} \\\\\frac{-3 \frac{+}{-} 1}{4}$

y = (-3 +- 1) / 4

X = -.05

X = -1

Y = 1

X-Intercepts: -.05, -1

Y-Intercepts: 1
