Can someone help me and explain this Algebra 2?

Tju [1.3M]

Nth term of gp = a(1 - r^n)/(1 - r), where n∞ = 10, n = ∞, a = 2, r < 1
10 = 2(1 - r^∞)/(1 - r)
10 = 2/(1 - r)
1 - r = 2/10 = 1/5
r = 1 - 1/5 = 4/5
An infinite deometric series with a beginning value of 2 that converges to 10 has common ratio of 4/5.

The first four terms are: 2, 1.6, 1.28, 1.024

4. BAKE SALE Ashley has $15 in the Pep

Mekhanik [1.2K]

Answer:

a) 187.5 b) Domain c ∈ [0,187.5] c) Range ∈ [0,15]

Step-by-step explanation:

a) In this function, d stands for dollars and c stands for cookies. Ashley left $15 to pay supplies for making new cookies. The more cookies they made the less money it is left. For instance, If someone bakes 1 cookie using that money:

d=15-0.08c d=15-0.08(1) d=14.92 Then $14.92 is left after baking 1 cookie. And so on.

To find the zero of this function, let's turn this into an equation.

$d=15-0.08c\\0=15-0.08c\\-15=-0.08c\\\ \frac{0.08}{0.08}c=\frac{15}{0.08}\\c=187.5$

So according to this function, with 15 dollars at least 187 cookies can be made.

b) The function d=15-0.08c if it was defined for the Real Set, any value would be valid within the Real Set. But c, is for cookies. Then the set is

$Z_{+}$

$d=15-0.08c\\0=15-0.08c\\-15=-0.08c\\\ \frac{0.08}{0.08}c=\frac{15}{0.08}\\c=187.5$

Domain c ∈ [0,187.5]

c) The Range

The Range is the subset of all values between $15 and 0$, since after the money is over they can no longer bake cookies. And there's $-1 dollar note.

So the Range is d ∈ [0,15]

The map below shows the path that Jin walked this morning. According to his pedometer, the total distance of this path was 2.3 k

max2010maxim [7]

Answer:

5 centimetres = 1 kilometre

Step-by-step explanation:

First add up the distances measured on the map.

1.1+4.8+2.2+3.4=11.5 cm

Based on this, since the number of cm is greater than the number of km, we can figure out that each cm should not be multiplied to get the km, so we can eliminate the first two answers.

Next write an equation to represent finding the scale

x=scale

11.5=2.3x

Now solve for the scale

11.5/2.3=2.3x/2.3

5=x

Therefore the scale is 5 centimetres = 1 kilometre
