-2, and 3

Step-by-step explanation:

-x² +x +6 = 0 is the same as

x²-x-6=0

but, x² -Sx+P=0

think what 2 numbers have the sum =1 and product = -6 that will be -2 and 3 witchh are your zeros

The result of a random survey showed that 40 out of 75 people plan to vote for Mr. Best for a position on the local store school

Anna35 [415]

Answer: 1,600 people

Step-by-step explanation:

The survey showed that 40 out of 75 people would vote for Mr. Best.

Convert this figure to a percentage so that you can use it to find out the number of people that would vote for him if numbers were larger:

= 40 / 75

= 53.33%

If 3,000 people voted, 53.33% would vote for Mr. Best which is:

= 3,000 * 53.33%

= 1,599.9

= 1,600 people

The slope of a line is the ratio of the change of y to the change of X. Name the trigonometric ratio of theta that equals the sl

Elanso [62]

Answer:

The trigonometric ratio of theta is tangent ⇒ answer (c)

Step-by-step explanation:

* Lets revise the trigonometry functions

- sinФ = the side opposite to angle Ф ÷ the hypotenuse

- cosФ = the side adjacent to angle Ф ÷ the hypotenuse

- tanФ = the side opposite to angle Ф ÷ the side adjacent to angle Ф

* Now read the definition of the slope and look to the figure

- The slope of a line is the ratio of the change of y to the change of x

∵ The change of y is opposite to angle Ф

∵ The change of x is adjacent to angle Ф

∴ The slope = the side opposite to Ф ÷ the side adjacent to Ф

* The slope of the line = tanФ

∴ The trigonometric ratio of theta is tangent
