Given a geometric sequence with a1 = 3 and r = 0.5, write the first three terms of the sequence

1 answer:

8 0

In a geometric sequence, the numbers are found by multiplying each number by a fixed amount called a common ratio(r).

a1....this is ur first number....so since a1 = 3, ur first number is 3...and to find ur next numbers, multiply each number by r, the common ratio (which equals 0.5)

first number = 3.......3 x 0.5 = 1.5
second number = 1.5......1.5 x 0.5 = 0.75
third number = 0.75

si the first 3 terms are : 3, 1.5, 0.75

Rus_ich [418]

Since we don't know how much Eric makes per dog, let's let x represent that value. Let's also let y represent our answer.

First, let's consider the two numbers we KNOW will be in the equation. The 56 that Eric made dog sitting and the 168 he made in total on Tuesday. Now, we're going to need to use subtraction and division in this equation.

(168 - 45) ÷ x = y

Hope this answer helped you out. :)

Use the side-splitter theorem to solve for x in the triangle below.

fiasKO [112]

Answer:

$x = 7$

Step-by-step explanation:

According to the side-splitter theorem, the two sides of the triangle is divided proportionally if the line that intersects both sides is parallel to the third side of the ∆.

Therefore, based on this theorem, we would have the following:

$\frac{x}{21} = \frac{8}{24}$

Solve for x

$\frac{x}{21} = \frac{1}{3}$

Multiply both sides by 21

$\frac{x}{21}*21 = \frac{1}{3}*21$

$x = \frac{21}{3}$

$x = 7$

Y=x2-4 what is the answer?

Brut [27]

Answer:

x=√y+4 or x=−√y+4

Step-by-step explanation:

Step 1: Add 4 to both sides.

x2−4+4=y+4

x2=y+4

Step 2: Take square root.

x=√y+4 or x=−√y+4
