Integers are like -4,-3,-2,-1,0,1,2,3,4 etc

√49=7, integer

-3⁰=-(3⁰)=-(1)=-1, integer

1.2 times 10⁻²=1.2/100=0.012, not an integer

18/3=6, integer

answer is 3rd one

Find the exponential function that passes through the points (2,80) and (5,5120)

juin [17]

Answer:

y = 5·4^x

Step-by-step explanation:

If you have two points, (x1, y1) and (x2, y2), whose relationship can be described by the exponential function ...

y = a·b^x

you can find the values of 'a' and 'b' as follows.

Substitute the given points:

y1 = a·b^(x1)

y2 = a·b^(x1)

Divide the second equation by the first:

y2/y1 = ((ab^(x2))/(ab^(x1)) = b^(x2 -x1)

Take the inverse power (root):

(y2/y1)^(1/(x2 -x1) = b

Use this value of 'b' to find 'a'. Here, we have solved the first equation for 'a'.

a = y1/(b^(x1))

In summary:

b = (y2/y1)^(1/(x2 -x1))
a = y1·b^(-x1)

For the problem at hand, (x1, y1) = (2, 80) and (x2, y2) = (5, 5120).

b = (5120/80)^(1/(5-2)) = ∛64 = 4

a = 80·4^(-2) = 80/16 = 5

The exponential function is ...

y = 5·4^x

Ifx <5 and x > C, give a value of c such that there

professor190 [17]

Answer:

For c=5 there are not solutions for the compound inequality

Step-by-step explanation:

we know that

In the compound inequality

$x < 5$ -----> inequality A

$x > c$ -----> inequality B

The solution of the system of inequalities must satisfy inequality A and must satisfy inequality B

If c=5

then

There is no solution that satisfies both inequalities simultaneously.

therefore

For c=5 there are not solutions for the compound inequality
