Answer:

x = 3

Step-by-step explanation:

Two secants drawn to a circle from an external point, then

The product of the measures of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant.

Thus

x × 12 = 4 × 9

12x = 36 ( divide both sides by 12 )

x = 3

Gerald graphs the function f(x) = (x – 3)2 – 1. Which statements are true about the graph? Select three options.
Phoenix [80]

Answer:

The answer is "Choice B, C, and F is correct".

Step-by-step explanation:

The following are choices, which is missing in the question, that can be defined as follows:

A) {x| x ≥ 3} is the domain.  

B) The set shall be {y| y ≥ –1}.  

C) over the interval  (–∞, 3), is the function, that decreases.  

D) it's over the duration the function increases its value, that is (–1, ∞).  

E) The symmetry axis will be x = – 1.  

F) vertex is (3, – 1).

  • In choice A, It is incorrect even though f is the domain, which is all true numbers because it has a quadrant function.  
  • In choice B, it is correct.  
  • In choice C, It is valid because it was a parable open with vertex so if we exploded view f (3, -1). Because as value opens up, its value with x from-∞ to 3 drops while it goes up from increasing from 3 to ∞.    
  • In choice D, It is wrong since we have just said f decreases from-∞ to 3. Therefore, f decreases from -1 to 3, too. Therefore, f doesn't grow from -1 to ∞.  
  • In choice E, It is incorrect because the symmetry axis is x = 3.  
  • In choice F, it is true.

4vir4ik [10]

Answer:

The experiment design used in this case is the between-subjected design.

Step-by-step explanation:

Between-subject design is a sort of experimental design where the individuals of an experiment are allocated to varied situations, with each individual being treated with only one of the experimental conditions.

In this case three similar ecosystems are designed containing a variety of insects and plants. Then each ecosystem to be exposed to rock music, country music, or a conventional city soundscape for two consecutive weeks.

Then after two weeks period they measured how successful the species were in each ecosystem.

The experiment design used in this case is the between-subjected design.

What is the variation constant for an inverse squared relationship where we know x = –4 and y = 3?
stich3 [128]
Let the constant be k.

For an inverse squared proportion the formula is y = k/x^2

Insert values of y and x into the formula.
3 = k/(-4)^2
3(-4)^2 = k
k = 3(16)
k = 48

Hope this helps. :)
