pantera1 [17]3 years ago

Answer:

The possible function is f(x)=(\frac{1}{4})^{x+2}

A is correct.

Step-by-step explanation:

The graph begins in the II quadrant and decreases quickly while crossing the ordered pair (-2,1).

When the graph enters the I quadrant, it begins to decrease slowly as it approaches the x-axis.

It is exponential decay function.

f(x)=ab^x

If 0<b<1 then decay.

According to option, possible function:

f(x)=(\frac{1}{4})^{x+2}

1/4 <1 , Decay function

We are given a passing point (-2,1)

If we put (-2,1) into f(x). It will satisfy.

Hence, The possible function is f(x)=(\frac{1}{4})^{x+2}

<span>f(x) = 1/4 to the power of x + 2= 627
f(x) = 1/4 to the power of x + 2= same thing as the one above
f(x) = 1/4 to the power of x - 2= 623
f(x) = 1/4 to the power of x − 2= same thing as the one above

I need help please!!!
kherson [118]

Answer:

Step-by-step explanation:

1. p║ q

50+130 = 180

If the same side interior angles are supplementary angles then the lines are parallel.

2. p║ q

70 = 70

If the corresponding angles are congruent the lines are parallels.

4. p║ q

x = x

If alternating exterior angles are congruent then the lines are parallel.

5. we do not know if p is parallel with q

We have given that 2 vertical angles are congruent yet that is not enough to tell us about the relation between the 2 lines.

7. For the lines p and q to be parallel we need the corresponding angles 3x and 45 to be congruent so therefore equal in measure.

3x= 45 , divide both sides by 3

x= 15

For x = 15 the p║ q

8. For the lines p and q to be parallel we need the corresponding angles 120 and (2x+10) to be congruent so therefore equal in measure.

2x+10 = 120, subtract 10 from both sides

2x = 110, divide both sides by 2

x = 55

For x = 55 the p║ q

Help me please ASAP
Mashutka [201]

Answer: \frac{5}{35}

Step-by-step explanation:

Since, the total number of contestant = 7,

Thus, the probability that out of 3 contestant, me and my friend is chosen

= \frac{2_C_2\times 5_C_1}{7_C_3}

= \frac{\frac{2!}{2!0!}\times \frac{5!}{1!\times 4!}}{\frac{7!}{4!\times 3!}}

= \frac{1\times 5}{\frac{7\times 6\times 5\times 4!}{4!\times 6}}

=  \frac{5}{35}

⇒ Third Option is correct.

Is 1/4 greater than or less than 3/9
den301095 [7]

Answer: Less

Step-by-step explanation: Ok lets make them both have a common denominator. This is 36. So 1/4 is going to be 9/36 and 3/9 is going to be 12/36

Find the error and explain why:
Sloan [31]

1)  9x + 2 = x + 5  ---> 9x + 2 = 6

subtracted X from one side but not the other

2) 3(x-4) + 5 = 12  ---> 3x + 4 + 5 = 12

didn't distribute correctly: 3(x-4)

multiplied the X by 3 but not the -4
