What is the rate of change for the sequence shown below. (1,2) (2,2.5) (3,3) (4,3.5) (5,4)
Nataly [62]

Answer:

0.5

Step-by-step explanation:

The given ordered pairs are: (1,2) (2,2.5) (3,3) (4,3.5) (5,4)

The corresponding sequence is :

2,2.5,3,3.5, 4,....

We can see that there is a common difference of d=0.5.

Better still we could use the slope formula:

m =  \frac{y_2-y_1}{x_2-x_1}

We substitute the point (1,2) and (2,2.5).

The rate of change of this sequence is:

m =  \frac{2.5 - 2}{2 - 1}  =  \frac{0.5}{1}  = 0.5

2 fractions have the same denominator. Which is the greater fraction: the fraction with the greater numerator or thr lesser nume
irinina [24]
If two fractions have the same denominator, that means the total number of parts is the same.  For example, you have two batches of cookies, which each have 8 cookies.

But the numerator tells you the number of parts you are dealing with.  Going back to our cookie example, say you ate 3 cookies and your little brother only had 1.  If you ate 3 cookies, you ate 3/8 of the cookies.  Your little brother ate 1/8 of the cookies.

So, which one is the greatest fraction?  In this case, who had more cookies?  That would be you.  So, the greater numerator means a greater fraction.

Answer: the fraction with the greater numerator

A conical paper cup has a radius of 2 inches. Approximate, to the nearest degree, the angle β (see the figure) so that the cone
Aneli [31]
I don't know where the angle β is, so I will make the assumption that tanβ = h/r
V = \frac{1}{3} \pi r^{2} h

V volume = 60
r radius = 2
h = r tanβ

tan \beta = \frac{3V }{ \pi  r^{3} } = \frac{ 180}{25,1} = 7,17 \\  \\  \beta = 82

If g(x)=2x-5 and f(x)=-x+3, which of the following represents f(g(x))?
Slav-nsk [51]

Answer: f(g(x))=-2x+8

*Note: you did not provide answer choices, but this should be the answer.

Step-by-step explanation:

f(g(x)) means you plug in g(x) into f(x).

f(g(x))=-(2x-5)+3

f(g(x))=-2x+5+3

f(g(x))=-2x+8
