The lengths of two sides of a triangle are 4 cm 4 cm and 20 cm . 20 cm. Identify the correct pair of measures between which the
Gennadij [26K]

Answer:

I think what you meant to say is "If a triangle has 2 sides that are 4 cm and 20 cm, what are the possible lengths of the third side?"

Basically, when given 2 sides of a triangle, the third side must be GREATER  than the DIFFERENCE of the other 2 sides and LESS than the SUM of the other 2 sides.

difference = 16 cm

sum = 24 cm

So, the third side must be greater than 16 cm and less than 24 cm

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.

Find the x-intercept and the y-intercept of the graph of the equation 7x + 25y = 12. Then graph the equation.
Vikki [24]

Answer: sorry, i couldn't graph it

but the equation was done.

7x+25y =12

                    rearrange it into y=mx+c

it becomes:

25y = -7x + 12

y= -0.28x+12

to find y intercept: x=0

so

y= -0.28*0+12

y=12

to find x intercept, y=0

so

0= -0.28x+12

0.28x = 12

x= 12/0.28

x= 42.857142857142857142857142857143‬

approximately = 43(whole number) or 42.9(one decimal place) or 42.86( 2 decimal places)
