Well you could factor out the 2 in the equation

6=3*2
10=5*2
4=2*2
so
6x^2-10x+4=2(3x^2-5x+2) so
factor 3x^2-5x+2 and get
(x-1)(3x-2)=0
so xy=0 then x and/or y=0 so
x-1=0
x=1

3x-2=0
3x=2
x=2/3

x=1 or 2/3

Which expressions are equivalent to −tan⁡ θ?
zzz [600]

Answer:

−1/cotθ

1/cot(−θ)

tan(−θ)

Step-by-step explanation:

The tangent function is a the ratio for an angle defined as opposite / adjacent.  A negative applied to −tan⁡ θ will give the opposite value. This is also true for the function when taken on a negative angle. tan(−θ) = −tan⁡ θ. This identity is also true for sin, sec, and cot. Recall that cotangent is the reciprocal of tangent and is defined as the ratio adjacent / opposite. Taking the reciprocal of cotangent will be the same as tangent. Using this information the following are equivalent:

1/cotθ

−1/cotθ  ----> The reciprocal of Cot is Tan

1/cot(−θ) ----> The reciprocal of Cot is Tan and cot(−θ) = −cot⁡ θ.

−1/cot(−θ)

tan θ

tan(−θ)----> tan(−θ) = −tan⁡ θ

PLEAASE HELP & EXPLAIN!!
belka [17]

Answer:

38.18%

Step-by-step explanation:

Experimental probability is probability that is determined on the basis of the results of repeated experiments.

Experimental Probability = The number of times a result happens / The number of times the experiment is carried out *100%

In this problem, The number of times a result happens is the number of times Pedro sees heads, which is 21. The number of time the experiment is carried out is 55.

So the result is 55/21 *100% = 38.181818... * 100%= 38.18%

Hope you learn with joy and high grades !
