Answer:  y = 1.125x  

Step-by-step explanation:

Divide the amount in dollars by the number of euros.

9/8 = 1.125

45/40 = 1.125

Since the constant change is 1.125, the input the  1.125 into the formula y=kx for k  to get the equation   y = 1.125x

The first term of an arithmetic sequence is 5. if the25th term is 101 find the common difference?
d1i1m1o1n [39]
An arithmetic sequence is one where each term is a constant difference, called the common difference, from the preceding term.  The arithmetic sequence can always be expressed as:

a(n)=a+d(n-1), a=first term, d=common difference, n=term number.

We are given two terms and term numbers, so we can solve for the common difference...

101=5+d(25-1)

101=5+25d-d

101=5+24d

96=24d

d=4

So the common difference is 4.

The function f(x) = x^3 is transformed to f(x) = 4x^3. Which statement describes the graph of the transformed function?
Natalka [10]

Answer: Option D.

Step-by-step explanation:

The translation is defined as

g(x)=kf(x)

Where, k is stretch factor.

If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.

It is given that,

f(x)=x^3

After transformation the function becomes

f(x)=4x^3

here, k=4>1, so the graph was stretched vertically by a factor of 4.

Therefore, the correct option is D.
