Ok so the total amount the mom paid is 50.50. It says she bought 10 journals at 2.50 each so subtract 25 which leaves 25.50. Then it says 2 markers at 5 each so subtract 10 which leaves 15.50. Then it states she paid 4.10 in annoying sales tax. So subtract 4.10 and you get 11.40 which is the remaining, which means thatbis how much she spent on a mouse.

I tried to figure it out but i can't. i need to show the work and i don't know how to do it.​
Andreas93 [3]

Integration Formula:

\int\limits {x}^{n} \, dx =\frac{x^{n+1}}{n+1} + C

Integrate each term:

\int\ {x^{2}} \, dx = \frac{x^{3}}{3}

\int\ {x} \, dx =\frac{x^2}{2}

\int\ {5} \, dx = 5x

\int\ {x} \, dx =\frac{x^2}{2}

\int\ {2} \, dx = 2x

Altogether this becomes:

\frac{\frac{x^3}{3} - \frac{x^2}{2}-5x }{ \frac{x^2}{2}+2x}

Your limits are 1 and 2. Substitute both numbers into the equation and minus them from each other.

x = 2:

\frac{\frac{2^3}{3} - \frac{2^2}{2}-5(2) }{ \frac{2^2}{2}+2(2)}

-

x = 1:

[tex]\frac{\frac{1}{3} - \frac{1}{2}-5 }{ \frac{1}{2}+2}[/tex]

x = 2:

\frac{\frac{8}{3} - \frac{4}{2}-10 }{ \frac{4}{2}+4}

-

x = 1: \frac{\frac{8}{3} - 2-10 }{ 2+4}

=

-1.212317928

Now convert all the answers to integers and see which one matches -1.212317928:

Because it's a negative number, we know it can only be A or B.

(A) = -1.212317928

(B) = -1.19047619

The answer is A: -\frac{3}{2} +In\frac{4}{3}

<h2>(A) - 3/2 = ln 4/3</h2>

ONLY GIVING BRAINLYEST IF YOU ANSWER QUICKLY AND CORRECTLY
k0ka [10]

Answer:

B and D

Step-by-step explanation:

First, you have to solve the first equation. (Hint: you use the distributive property.)

2(5x + 2 + x)

10x + 4 + 2x

12x + 4

We can already see that B is correct and A is incorrect.

Now to solve C and D.

C = 2(5x + 3)

10x + 6

This is incorrect.

D = 2(6x + 2)

12x + 4

This is correct.

Use the data set below to determine measurements of central tendency. (45, 65, 30, 50, 20, 30)
USPshnik [31]
Mean: [45+65+30+50+20+30]/6 = 40.2

Median

First order the number {20, 30, 30,45, 50, 50}

The median is the average of the two values in the middle of the list: (30+45)/2 = 37.5

Mode: 30 and 50 (they are repeated the same number of times)

How does the order of the numbers affect the product in multiplication problems
GalinKa [24]

Answer:

Uneffected.

Step-by-step explanation:

The order of the numbers doesn't affect the product in multiplication problems.

For example, we need to multiply 2 × 10.

We can write it as : 2×5×2

2×(5×2) = 2×10 = 20

Also,

(2×5)×2 = 10×2 = 20

Hence, it will remain unaffected when we multiply numbers.
