Answer:

$\boxed{ 15}$

Step-by-step explanation:

→ We know that on the right side the length of the 2 sides is 18 and one of them is 10 so,

18 - 10 = 8cm is the length of the line above 10cm

→ Now we use scale factor enlargement, we can see that opposite 12 is 8 so the multiplier that was used to get from 12 to 8 is,

12 ÷ 8 = 1.5

→ Now we know the multiplier is 1.5 and we need to find the side opposite 10 so we multiply 1.5 by 10 to get,

1.5 × 10 = 15

Answer: 15

<u>Step-by-step explanation:</u>

Set up the proportion as follows:

$\dfrac{18}{10}=\dfrac{12+x}{x}\\\\\\18x=10(12+x)\\\\\\18x=120+10x\\\\\\8x=120\\\\\\x=\dfrac{120}{8}\\\\\\x=\large\boxed{15}$

Based on the graphs of f (x) and g(x), in which interval(s) are both functions increasing? Polynomial function f of x, which increases from the left and passes through the point negative 5 comma negative 4 and goes to a local maximum at negative 4 comma 0 and then goes back down through the point negative 3 comma negative 2 to a local minimum at the point negative 2 comma negative 4 and then goes back up through the point negative 1 comma 0 to the right, and a rational function g of x with one piece that increases from the left in quadrant 2 asymptotic to the line y equals 1 passing through the points negative 6 comma 2 and negative 3 comma 5 that is asymptotic to the line x equals negative 2 and then another piece that is asymptotic to the line x equals negative 2 and increases from the left in quadrant 3 passing through the point negative 1 comma negative 3 and 2 comma 0 that is asymptotic to the line y equals 1 (–°, °) (–°, –4) (–°, –4) ∪ (–2, °) (–°, –4) ∪ (2, °)

What would be the equation for #23???

Rufina [12.5K]

Hi there!

Let r be the number of matches that Rebecca's team won.

We know that Katheryn's team won 9 more matches than Rebecca's team, and we know that Katheryn's team won 52 matches.

Using this given information, we can create the following equation.

$r+9=52$

If you wish to solve this, we can subtract both sides by 9 to get the following value for r.

$r=43$

Have an awesome day! :)

What is the sum of a geometric series Sn=a+ar+ar2+ar3+…+arn-2+arn-1?

algol13

Answer:

$Sn= \frac{a(1-r^n)}{1-r}$

Step-by-step explanation:

A geometric sequence is a sequence such that any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r. The common ratio (r) is obtained by dividing any term by the preceding term.

from the given expression

the given data are

first term a1= $a$
