We can assign the value "2x" as the amount of money that Amelia which to achieve in twelve years.
So, his initial money is X.
We can try each percent to test if it could double the amount in 12 years.
x+0.06*12years*x=1.72X
x+0.12*12*x=1.44x
x+0.1*12*x=2.2x
x+0.166*12*x=2.992x

Therefore, the answer is 10 percent.

I need some help with this calculus 1 question.
Cerrena [4.2K]

Answer:

(a) f'(1)=-4

(b) y+4x-4=0

Step-by-step explanation:

<u>Tangent Line of a Function</u>

Given f(x) a real differentiable function in x=a, the slope of the tangent line of the function in x=a is given by f'(x=a). Where f' is the first derivative of f.

We are given

y=x-x^5

The derivative is

y'=1-5x^4

(a) The slope of the tangent line at (1,0) is

f'(1)=1-5\cdot 1^4=-4

f'(1)=-4

(b) The equation of the tangent line can be found with the general formula of the line:

y-y_o=m(x-x_o)

Where m is the slope and the point (xo,yo) belongs to the line. We have m=-4, xo=1, yo=0, thus

y-0=-4(x-1)

Or, equivalently

y+4x-4=0

Using desmos
VMariaS [17]

The attached graph represents the location of the pH values 0 and 1

<h3>How to plot the points?</h3>

The given parameters are:

pH value 0 = (1, 0)

pH value 1 = (0.1, 1)

This means that we plot a point at the coordinate (1, 0) and another point at the coordinate (0.1, 1).

See attachment for the graph

Convert 86.25 into hexadecimal. ​
Romashka-Z-Leto [24]

Answer:

56.4

Step-by-step explanation:

To convert decimal number 86.25, we convert its integer and fraction part individually and then add them to get the equivalent hexadecimal number, as below:

To convert integer 86 to hexadecimal, follow these steps:

Divide 86 by 16 keeping notice of the quotient and the remainder. Continue dividing the quotient by 2 until you get a quotient of zero.

Then just write out the remainders in the reverse order to get the equivalent hexadecimal number.

86 / 16 = 5 with remainder 6

5 / 16 = 0 with remainder 5

Here is the answer to 86 decimal to hexadecimal number:

56

For converting decimal fraction 0.25 to hexadecimal number, follow these steps:

Multiply 0.25 by 16 keeping notice of the resulting integer and fractional part. Continue multiplying by 16 until you get a resulting fractional part equal to zero (we calcuclate upto ten digits).

Then just write out the integer parts from the results of each multiplication to get equivalent hexadecimal number.

0.25 × 16 = 4 + 0

Here is the answer to 0.25 decimal to hexadecimal number:

0.4

Therefore, decimal number 86.25 converted to hexadecimal is equal: 56.4

A dietitian at a hospital wants a patient to have a meal that has 126 grams of protein, 82 grams of carbohydrates, and 101.5 mil
katovenus [111]
<h3>The dietitian provide 2.5 numbers of salmon steak, 1 baked egg and 2 acorn squash for the patient. </h3>

Step-by-step explanation:

Let

Number of salmon steak = x

Number of baked eggs =y

and Number of acorn squash =z

Total amount of protein that is provided to the patient =40 x +20 y+3 z

Total amount of carbohydrates that is provided to the patient = 20 x+2y +15z

Total amount of vitamin A that is provided to the patient = x+25 y+ 37z

According to the problem,

40x+20y+3z=126,     20x+2y+15z=82    and   x+25y+37z= 101.5

Solving the above equations

we get x= 2.5 ,y= 1 and z=2

So ,  The dietitian provide 2.5 numbers of salmon steak, 1 baked egg and 2 acorn squash for the patient.
