Answer:

The correct option is

The polynomial is prime.

Step-by-step explanation:

we have to select the true statement for the equation

x^2+8x-6

As, we know if b^2-4ac is a positive perfect square integer, then the trinomial can be factored over the rational numbers. Otherwise, we cannot factor ax^2 + bx + c over the rational numbers,

so the trinomial is considered to be prime.

Equation: x^2+8x-6

a=1, b=8 and c=-6

b^2-4ac=8^2-4(1)(-6)=64+24=88

which is not a perfect square integer.

Hence, the above trinomial can not be factored into lowe degree.

⇒ Given polynomial is prime.

hence, option 4 is correct.

3x-y+2=0 in rectangle form
kotegsom [21]

Complete Question:

Convert 3x-y+2=0 in rectangle form to polar form

Answer:

r ( 3cosθ - sinθ) = -2

Step-by-step explanation:

The equation so given is already in rectangular form, the task is to convert it to polar form.

3x - y + 2 = 0

To transform an equation from the rectangular to the polar coordinate:

x = r cosθ

y = r sinθ

Substitute the representations for x and y into the given equation:

3(r cosθ) - (r sinθ) + 2 = 0

3rcosθ - rsinθ = -2

The polar representation of the equation then becomes:

r ( 3cosθ - sinθ) = -2

The price of a toaster increase 10% to $40. What is the original price of the toaster before the increase?
tresset_1 [31]

Answer:

36.36

Step-by-step explanation:

We can express 10% as a decimal by multiplying it by (1/100), resulting in 0.1. Therefore, adding 0.1 of the original price, or x, to the price will result in 40, so x+0.1*x=40

          = 1.1x

Dividing both sides by 1.1, we get that x, or the original price, is $36.36 (approximately).
