List the first 4 terms of a geometric sequence with a first term of 2 and a common ratio of 5? I'm really struggling... there is

one similar for the next question too. It's the same, but the first term is 4 and the common ratio is 4. Thanks for the help

In general, a geometric sequence with first term a and common ratio r has terms a, ar, ar², ar³, etc.

First geometric sequence: 2, 10, 50, 250

Second geometric sequence: 4, 16, 64, 256

i hope this helped! :D

2.85 rounded to the nearest hundredth <br> A. 2.861<br> B. 2.849<br> C. 2.842<br> D. 2.805

blagie [28]

Answer:

B) 2.849

Step-by-step explanation:

Given: 2.85 which is rounded to the nearest hundredth place.

To find the number, the thousandth place must be greater than or equal to 5.

Here 2.849 has the thousandth place greater than 5

When we round off 2.849 to the nearest hundredth place, we get

2.85

Therefore, answer is B) 2.849

Hope this will helpful.

Thank you.

Solve the system of equations (1 point)<br> y = 2x(squared) – 3<br> y = 3x - 1

════════════════════

1.

$y = {2x}^{2} - 3$

${2x}^{2} - 3 = y$

${2x}^{2} = y + 3$

$\frac{2x^{2}} {2} = \frac{y + 3}{2}$

${x}^{2} = \frac{y + 3}{2}$

$x = \sqrt \frac{2y + 6}{2}$

───────────────────

2.

$y = 3x - 1$

$3x - 1 = y$

$3x = y + 1$

$\frac{3x}{3} = \frac{y+1}{3}$

$x = \frac{y + 1}{3}$

The sum of two numbers is 30. The larger number is 6 more than the smaller number. Find the two numbers

Sati [7]

Let b>a

We are told that b=a+6 and that a+b=30

Using the value of b=a+6 in a+b=30 gives you:

a+(a+6)=30 combining like terms on left side

2a+6=30 subtract 6 from both sides

2a=24 divide both sides by 2

a=12, and since b=a+6

b=18

So the two numbers are 12 and 18.

Jason started with d dollars in his piggy bank. One week late, Jason doubled the amount in his piggy bank. Another week later, j

elena55 [62]

Given, Jason had an amount of $d in the piggy bank.

After one week, Jason doubled the amount in the piggy bank.

So, after one week the amount in the piggy bank = $ $(2)(d)$ = $(2d)

Another week later, Jason added $20 in the piggy bank.

So after another week, the total amount in the piggy bank = $ $(2d+20)$

Given, that time the piggy bank had $50 in it.

So we can write the equation as,

$2d+20 = 50$

To find the value of d, we will move 20 to the right side by subtracting it from both sides. We will get,

$2d+20-20 = 50 - 20$

$2d = 50 -20$

$2d = 30$

Now to find d, we will move 2 to the right side by dividing it to both sides. We will get,

$\frac{2d}{2}=\frac{30}{2}$

$d = 15$

We have got the required answer.

The value of d = $15.
