After sales tax is added the total cost of a $58 purchase $61.48 what is the sales tax rate on the purchase?

Answer:

A trinomial with a leading coefficient of 3 and a constant term of -5 is .

Step-by-step explanation:

To find : A trinomial with a leading coefficient of 3 and a constant term of -5 ?

Solution :

A trinomial is a polynomial with three terms is in the form of .

where, a is the leading coefficient,  b is the middle coefficient of x and c is the constant.

A trinomial with a leading coefficient of 3 and a constant term of -5.

Here, a=3,c=-5 and consider b=1,

So,

Therefore, a trinomial with a leading coefficient of 3 and a constant term of -5 is .

Final answer:

A trinomial with a leading coefficient of 3 and a constant term of -5 can be represented as 3x^2 + 4x - 5, where 3 is the leading coefficient and -5 is the constant term.

Explanation:

In mathematics, a trinomial is an algebraic expression made up of three terms. In your case, you are asking for a trinomial with a leading coefficient of 3 and a constant term of -5. An example of such a trinomial could be 3x2 + 4x - 5. Here, 3 (the coefficient of the x2 term) is the leading coefficient, and -5 (the term without any variable) is the constant term.

Answer:

θ = 240

and

cos(θ) = -0.5

Step-by-step explanation:

Theta is in the third quadrant, that meansit goes from 180 to 270 degrees

Then,

cos^2 (θ) =1/4

cos (θ) = ± 1/2

θ = arccos(0.5)

θ = 60

But in the third quadrant

θ = 180 + 60  = 240

θ = 240

and

cos(θ) = -0.5

Answer:

Option C. $6,012

Step-by-step explanation:

we know that

The  formula to calculate the depreciated value  is equal to

where  

V is the the depreciated value  

P is the original value  

r is the rate of depreciation  in decimal

t is Number of Time Periods  

in this problem we have  

t = 7 years

P = $8,000

r = 0.04

substitute in the formula above

Hope this helps :)
