If a sum invested gains 10% each year how long will it be before it has doubled its
value?

Answers

Answer 1

Using an exponential equation, it is found that it will be 7.3 years before the value is doubled.

The equation for an increasing exponential function is given by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

A(0) is the initial amount.r is the growth rate, as a decimal.

In this problem:

Gains 10% each year, thus [tex]r = 0.1[/tex].

The doubling time is t for which [tex]A(t) = 2A(0)[/tex], then:

[tex]A(t) = A(0)(1.1)^t[/tex]

[tex]2A(0) = A(0)(1.1)^t[/tex]

[tex](1.1)^t = 2[/tex]

[tex]\log{(1.1)^t} = \log{2}[/tex]

[tex]t\log{1.1} = \log{2}[/tex]

[tex]t = \frac{\log{2}}{\log{1.1}}[/tex]

[tex]t = 7.3[/tex]

It will be 7.3 years before the value is doubled.

Balto” is a 6 year old 35 kg intact husky mix. He presents through the ER after likely being HBC (hit by car) with anisocoria and nystagmus, both signs of head trauma. The doctor instructs you to give 1 g/kg mannitol IV to decrease intracranial pressure. Mannitol is a 20 % solution. How many grams will “Balto” receive? How many mgs? How many mls?

Answers

If we give 1 g/kg  of mannitol, it then follows that Balto needs to receive 35g  of  mannitol.

What is percent concentration?

Percent is one of the ways of expression the concentration of a solute in a solvent. In this case, the concentration of the mannitol is 20%. This implies that there are 20 g of mannitol in 100 g of solution.

Thus, If we give 1 g/kg  of mannitol, it then follows that Balto needs to receive 35g  of  mannitol.

Simplify the left side:

(2 + √3)/(2 - √3) = (2 + √3)(2 + √3)/(2 + √3)(2 - √3) =(4 + 4√3 + 3)/(4 - 3) =7 + 4√3

or security​ reasons, a company will enclose a rectangular area of 11,200 m2 in the rear of its plant. One side will be bounded by the building and the other three sides by fencing. If the bounding side of the building is 150 m long and 300 m of fencing will be​ used, what will be the dimensions of the rectangular​ area?

Answers

The dimensions of the rectangle are 150 m and 75 m respectively.

Let x be the length of the rectangular area and y be the width of the rectangular area.

Its area A = xy

Given that its area is 11,000 m², xy = 11000 m² (1)

Also, since the bounding side of the building is 150 m long and the fencing is 300 m, the perimeter of the rectangular area is P = 150 m + 300 m = 450 m.

Also, the perimeter of the rectangular area is P = 2(x + y)

Since P = 450 m

2(x + y) = 450 m

x + y = 225 m (2)

Since the bounding side of the building represents one dimension of the rectangle, x = 150 m.

Substituting x into (2), we get the other dimension

x + y = 225

150 + y = 225

y = 225 m - 150 m

y = 75 m

So, the dimensions of the rectangle are 150 m and 75 m respectively.

A student in a foreign language program learns 15 new words each week. Which graph best represents the relationship between x, the number of weeks the student has been in the program and y, the total number of new words the student has learned

Linear equations are represented by straight line.

The required graph is graph (a).

The given parameters are:

[tex]\mathbf{Rate =15}[/tex]

Let x represents the number of weeks, and y represents the number of words in week x.

So, we have:

[tex]\mathbf{y = Rate \times x}[/tex]

Substitute 15 for Rate

[tex]\mathbf{y = 15\times x}[/tex]

[tex]\mathbf{y = 15x}[/tex]

The above equation means that:

1. given w(x)=4x
a. graph r(x)=4 x w(x). then complete the table of corresponding points on r (x). How do you graph this?

Answers

Answer:

Step-by-step explanation:

a). When graph w(x) is transformed to r(x) = 4 × w(x), graph of w(x) is vertically  stretched by a scale factor of 4.

Table for the corresponding points will be,

x               w(x)                  r(x)

0                0                  0×4 = 0

15              60               60×4 = 240

30             120             120×4 = 480

45             180             180×4 = 720

b). As discussed in part (a), graph of w(x) will be vertically stretched by a scale factor of 4 to produce the graph of r(x).

c). Since, w(x) = 4x

  and r(x) = 4[w(x)]

  r(x) = 4(4x) = 16x

 r(x) = 16x
