What is the difference between (Picture 1) and (picture 2)? A. 0 B. 2 C. 5 D. 6

Vesnalui [34]

Answer:

The difference between the picture is 0 , option A .

Step-by-step explanation:

Given two figures as :

In figure A

The expression is 1 + 3 n , where n lies from 0 to 4

So , let f (n) = 1 + 3 n

Or,f ( n ) = 1 + 3 ×0 = 1 + 0 = 1

f ( 1 ) = 1 + 3 ×1 = 1+ 3 = 4

f ( 2 ) = 1 + 3 ×2 = 1+ 6 = 7

f ( 3 ) = 1 + 3 ×3 = 1+ 9 = 10

f ( 4 ) = 1 + 3 ×4 = 1+ 12 = 13

so, summation of ( 1 + 3 n ) from n = 0 to 4 = 1 + 4 + 7 + 10 + 13 = 35

In figure B

The expression is 3 i - 5 , where i lies from 2 to 6

So , let g (i) = 3 i - 5

Or,g ( 2 ) = 3 ×2 - 5 = 6 - 5 = 1

g ( 3 ) = 3 ×3 - 5 = 9 - 5 = 4

g ( 4 ) = 3 ×4 - 5 = 12 - 5 = 7

f ( 5 ) = 3 ×5 - 5 = 15 - 5 = 10

f ( 6 ) = 3 ×6 - 5 = 18 - 5 = 13

so, summation of ( 3 i - 5 ) from i = 2 to 6 = 1 + 4 + 7 + 10 + 13 = 35

So, The difference between the summation of functions f(n) - g(i) is

f(n) - g(i) = 35 - 35

I.e f(n) - g(i) = 0

Hence The difference between the picture is 0 , option A . Answer

Solve the equation. Round to the nearest thousandth. -12e-x + 8 = 7

Marysya12 [62]

Answer:

-12e-x + 8 = 7

-12e-x = 7-8

-12e-x = -1

12e-x = 1

e-x = 1/12

ln(e-x) = ln(1/12)

x = -ln(1/12)

x = -2.485

John is making trail mix he mixed 10.33 cups of raisins 12.25 cups of pretzels and 7.50 cups of chocolate to make 4 servings est

Mariulka [41]

Answer: 30.1

Step-by-step explanation:

Cups of raisins mixed= 10.33

Cups of pretzels mixed= 12.25

Cups of chocolate mixed= 7.50

When each ingredients is rounded to the nearest tenths, it will be:

Cups of raisins mixed= 10.3

Cups of pretzels mixed= 12.3

Cups of chocolate mixed= 7.5

Total trail mixed by John= 10.3 + 12.3 + 7.5 = 30.1

30.1 cups was mixed together by John.

Jackie follow the steps to elevate the expression 15 - (37 + 8) divide 3 37 + 8 = 45 45-15= 30 30 divided by 3 = 10 Mark looks a

damaskus [11]

Answer:

So, we conclude that Mark is right.

Step-by-step explanation:

If we have the following expression: 15 - (37 + 8) : 3.

We will first divide the value we get in parentheses and then subtract it.

Because sharing is an older mathematical operation than subtraction. Therefore, we get:

$15-(37+8):3=15-45:3=15-15=0$

So, we conclude that Mark is right.
