Answers

Answer 1

Answer:

-1-2-4-8-16

Step-by-step explanation

Answer 2

The solution is, 1-2 + 4-8 + 16, is the correct expanded form for the series Σ-2^n, n = 0 to 4.

What is an exponent in math?

An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.

here, we have,

given that,

the  series Σ-2^n, n = 0 to 4.

now, we have to find,

the correct expanded form for the series ,

as , we get,

the value of n = 0 to 4

so, putting the value of n = 0,1,2,3,4

we get the series as,

Σ-2^n

= -2^0 + (-2)^1 + (-2)^2 + (-2)^3 + (-2)^4

= 1 -2 + 4 - 8 +16

Hence, The solution is, 1-2 + 4-8 + 16, is the correct expanded form for the series Σ-2^n, n = 0 to 4.

Two Forest Ranger stations are located 9.8 miles apart. They both receive the same distress call. They determine that from Ranger Station 1 the distress call is at an angle of 46° and from Ranger Station 2 it is at angle of 52°. Which ranger station is closer to the distress call and by how much?

Answers

Answer:

Ranger station 2 is closer by 3.47 miles

Step-by-step explanation:

tan(46)=O/9.8

O (ranger station 2 to distress call)=10.15 miles

sin(46)=9.8/H

H (ranger station 1 to distress call)=13.62 miles

13.62-10.15=3.47 miles

So, ranger station 2 is closer by 3.47 miles

On Tuesday, Marissa was $45 short of her fundraising goal. The next day, she was $5 over her goal write an equation to show how much she raised in one day.

Answers

Answer: Hello daema, let's let x be the goal and c be the collection per day.

x - 45 + c = x + 5 is the answer so now let's talk about how we did that.

So she wants to get to x which is the goal. But right now she has 45 less than what her goal is. So that would look like this x - 45 now she has to get c or the collection per day to get to her goal. So now it looks like this x - 45 + c. Now that c has to be at least x which is her goal, it now will look like this x - 45 + c = x. But we're not done, the question said that now she 5$ over her goal, or x. So we have to add the + 5 onto the end so now it looks like this x - 45 + c = x + 5. To solve the equation "if you have to" it would be x = 50$ per day.

Answers

Answer:

1:47:92:34:31:7

Step-by-step explanation:

Reduced ratios are found by removing (dividing out) the greatest common factor (GCF). For several of these, that factor is the smallest number or the difference between the numbers. Knowledge of multiplication tables is helpful.

  9 : 36 = 1 : 4 . . . . common factor of 9

  21 : 27  = 7 : 9 . . . . common factor of 3

  48 : 72 = 2 : 3 . . . . common factor of 24

  60 : 45 = 4 : 3 . . . . common factor of 15

  10 : 70 = 1 : 7 . . . . common factor of 10

_____

Comment on GCF

The greatest common factor can be found from your knowledge of multiplication tables and/or divisibility rules. It can also be found using Euclid's algorithm. For that, you ...

  Divide the larger number by the smaller and keep the remainder.

  If the remainder is 0, the smaller is the GCF.

  If the remainder is not zero, replace the larger number with the remainder and repeat from the first step.

Example:

  27/21 = 1 r 6

  21/6 = 3 r 3

  6/3 = 2 r 0 . . . . 3 is the GCF of 21 and 27

sarah started the school year with 14 drawings in her notebook and draws 5 more each day. whats the linear equation?

Answers

Answer:

y = 5x + 14

Step-by-step explanation:

Let x = number of day and y = number of drawings.

She draws 5 drawings per day, so in x days, she draws 5x drawings.

She started with 14 drawings, so the total number of drawings in any day, x, is

5x + 14.

The equation is

y = 5x + 14
