Answer:To graph y = 4, we make a horizontal line at 4 on the y axis. See image 1

Since it is a horizontal line on the y axis, no matter the input you have for x, the y value is going to be 4. So the points  (4, ) (5, )  =  (4, 4) (5,4 ) 

For your point ( , 2.59), this is saying y = 2.59 The missing value would be 0. our points are below assuming the information given is complete:

(4, ) (5, ) ( ,2.59)  =  (4, 4) (5,4 ) (0,2.59)

What is a simplified form of the expression (5^2)-^2Divided by 5^3
laila [671]

Answer:

5^ -7  =1 / 5^7

Step-by-step explanation:

(5^2)-^2/ 5^3

We know that a^b^c = a^(b*c)

(5^2)-^2 = 5^(2*-2) = 5^-4

5^-4/  5^3

We know that a^b /a^c = a^ (b-c)

5 ^ (-4-3)

5^ -7

If we don't want to use negative exponents

We know that a^ -b = 1/ a^b

1 / 5^7

One hundred rats are being trained to run through a maze and are rewarded when they run through it correctly. Once a rat success
Assoli18 [71]

Answer:

6 trials

Step-by-step explanation:

The number of rats that run the maze incorrectly after t trials ;

N(t) = 100e^-0.14t

Initial number of rats = 100

45% of rats to run the maze incorrectly ; 45% * 100 = 45 rats

N(t) = 45

N(t) = 100e^-0.14t

45 = 100e^-0.14t

45/100 = e^-0.14t

0.45 = e^-0.14t

Take the In of both sides :

In(0.45) = In(e^-0.14t)

- 0.798507 = - 0.14t

Divide both sides by -0.14

- 0.798507 / - 0.14 = - 0.14t / - 0.14

5.7036 = t

To the nearest whole number :

Number of trials, t = 6 trials

1.<br>1. The factors of 64a3 + 343b3 are​
laiz [17]

Answer:

(4a + 7b)(16a² - 28ab + 49b²)

Step-by-step explanation:

Use the sum of two cubes to factor

In addition

a³ + b³ = (a + b)(a² - ab + b²)

In subtraction

a³ - b³ = (a - b)(a² + ab + b²)

64a³ + 343b³ = (4a + 7b)(16a² - 28ab + 49b²)

P varies directly with T and p=10 when T=500. When T=509, find T
Zepler [3.9K]

Answer:

Let,

P= kT

P = 10, when T = 500

So, 10=k500

or, k=10/500

or, k=1/50

When T=509

P=kT

or, P=(1/50)×509

or, P=508/50

or, P = 10.18

And when P = 509 (since the question isn't clear)

509=(1/50)×T

or, T=509×50

or, T=25450
