Option A

The simple interest earned over 6 years is $ 4050

<em><u>Solution:</u></em>

Martha invested a principal amount of $15,000 into a savings account that earns simple interest at a rate of 4.5% per year

<em><u>The formula for simple interest is given as:</u></em>

Simple\ Interest = \frac{p \times n \times r}{100}

Where, "p" is the principal and "n" is the number of years and "r" is the rate of interest

From given,

p = 15000

r = 4.5 %

n = 6 years

<em><u>Substituting the values we get,</u></em>

Simple\ Interest = \frac{15000 \times 4.5 \times 6}{100}\\\\Simple\ Interest = 150 \times 4.5 \times 6\\\\Simple\ Interest = 4050

Thus simple interest earned over 6 years is $ 4050

Sistemas de ecuaciones

Answer:

El Dr. Potter aplicó 32 vacunas de polio y 28 de sarampión.

Step-by-step explanation:

- First, the data must be taken into account to create the equations:

  •  X + Y = 60;    (Equation 1)

- Where:

 X = Number of polio vaccines and Y = Number of measles vaccines.

  •  4X + 2Y = 184;     (Equation 2)

Where for each polio vaccine there are 4 doses and for each measles vaccine there are 2 doses.

- We clear the variable that we want to find in each equation:

  • Y = 60 - X;     (And we call it equation 3)
  • Y = (184-4X) / 2;     (And we call it equation 4)

- Now both equations are equalized in terms of the same variable:

  • 60 - X = (184 - 4X) / 2

- Then X is cleared to find its value:

  • 120 - 2X = 184 - 4X
  • 4X - 2X = 184 - 120
  • 2X = 64
  • X = 32

- Now we demonstrate the value of X obtained in equation 1 or 2 to give the values ​​of Y

  • (32) + Y = 60
  • Y = 60 - 32
  • Y = 28

- Finally, both values ​​are used to see if equation 2 gives us the correct data:

  • 4 (32) + 2 (28) = 184
  • 128 + 56 = 184

- The answer is given:

Dr. Potter gave 32 polio and 28 measles vaccines.

Integration: How would I get to this answer?
Scrat [10]
Given that y attains a maximum at x=1, it follows that y'=0 at that same point. So integrating once gives

\displaystyle\int\frac{\mathrm d^2y}{\mathrm dx^2}\,\mathrm dx=\int-8x\,\mathrm dx
\dfrac{\mathrm dy}{\mathrm dx}=-4x^2+C_1
\implies -4(1)^2+C_1=0\implies C_1=4

and so the first derivative is y'=-4x^2+4.

Integrating again, you get

\displaystyle\int\frac{\mathrm dy}{\mathrm dx}\,\mathrm dx=\int(-4x^2+4)\,\mathrm dx
y=-\dfrac43x^3+4x+C_2

You know that this curve passes through the point (2, -1), which means when x=2, you have y=-1:

-1=-\dfrac43(2)^3+4(2)+C_2
\implies C_2=\dfrac53

and so

y=-\dfrac43x^3+4x+\dfrac53

-40-2(3m+1/2)=7m-2 what does m equal
kherson [118]

Answer: m = −3

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

<u>Step 1:</u> <em>Expand.</em>

−40 − 6m − 1 = 7m − 2

<u>Step 2:</u> <em>Simplify −40 − 6</em>m<em> − 1 to −6</em>m<em> − 41.</em>

−6m − 41 = 7m − 2

<u>Step 3:</u> <em>Add 6</em>m<em> to both sides.</em>

−41 = 7m − 2 + 6m

<u>Step 4:</u> <em>Simplify 7</em>m<em> − 2 + 6</em>m<em> to 13</em>m<em> − 2.</em>

−41 = 13m − 2

<u>Step 5:</u><em> </em><em>Add 2 to both sides</em>

−41 + 2 = 13m

<u />

<u>Step 6:</u> <em>Simplify −41 + 2 to −39.</em>

−39 = 13m

<u>Step 7:</u><em> </em><em>Divide both sides by 13.</em>

−\frac{39}{13} = m

<u>Step 8:</u> <em>Simplify </em>\frac{39}{13}<em> to 3.</em>

−3 = m

<u />

<u>Step 9:</u> <em>Switch sides.</em>

m = −3
