True or FalseIn order for a function to be one-to-one, no two independent variable values may yield the same value of the dependent variable

Answers

Answer 1
Answer: dependent variables are dependent on the independent variable ie
f(x)=8x
f(x)=demendent variable
x=independent

Answers

To find cirfumfrence we use the formula C = 2 \pi r
Soooo
\pi = 3.14
r = 40 inches
So now we plug it in :P
C = 2 x 3.14 x 40 = 251.2 
answer = B.) 251.2 inches

Answer: 151/20 < 7.611 < 7 5/8 < 8.66

Step-by-step explanation:

First convert the fractions to decimals.

151/20= 7.55

7 5/8 = 7.625  

The other two numbers are  7.611   and  8.66

In all the numbers the least is 7.55, then comes , 7.611, 7.625 and 8.66 .

The Probability of junior boys will be  (1)/(6) .

What is Probability ?

Probability is the ratio of the number of possible outcomes to the total number of outcomes.

We have,

Total number of boys = 12

Total Junior boys = 2

So,

Probability =(number\ of\ possible\ outcomes )/(total\ number\ of\ outcomes)

So,

P (Junior Boy) =(number\ of\ junior\ boys)/(total\ number\ of\ boys)

So,

P (Junior Boy) =(2)/(12)

i.e.

P (Junior Boy) =(1)/(6)

So,

The Probability of junior boys is (1)/(6) .

Hence, we can say that the Probability of junior boys will be  (1)/(6) .

all you have to do is find a number that both of them is divisible by and divide it by them. for example, when you divide it by 3, you will get 11/12
11/12 Divide both by 3.

A polynomial function has a root of -5 with multiplicity 3, a root of 1 with multiplicity of 2, and a root of 3 with multiplicity 7. If the function has a negative leading coefficient and is of even degree which statement about the graph is true?

a) function is positive on (-∞,-5)
b) fuction is negative on (-5,3)
c) function is positive on (-∞,1)
d) function is negative on (3,∞)​

Answers

Answer:

  d)  function is negative on (3,∞)​

Step-by-step explanation:

The even degree and negative leading coefficient tell you that the function is negative as x ⇒ ±∞. (Selections A and C cannot be correct.)

The odd multiplicity tells you the function crosses the x-axis at x=-5 and x=3, so will be non-negative between those values. (Selection B cannot be correct.)

The function is negative on (3, ∞).

Answer:

The graph of the function is positive on (-co, -5).

The graph of the function is negative on (3,co).

Step-by-step explanation:

We know that the roots are in: -5, 1 and 3.

and after 3, the graph is in the negative side, so between 1 and 3 the graph must be in the positive side, between -5 and 1 the graph must be in the negative side, and  between -inifinity and -5 the graph must be in the positive side:

So the statements that are true are:

The graph of the function is positive on (-co, -5).

The graph of the function is negative on (3,co).
