What’s the following sum?

Step-by-step explanation:

i)

Consider the exponential equation

[tex]y = a {e}^{bt} [/tex]

Now Substitute these points to get a and b value

(0,37000) , (1,20350)

[tex]37000 = a \times {e}^{b \times 0} [/tex]

[tex]37000 = a \times 1[/tex]

Hence a=37000

Now Substitute t=1

[tex]20350 = 37000 \times {e}^{b \times 1} [/tex]

[tex] \frac{20350}{37000} = {e}^{b} [/tex]

[tex]0.55 = {e}^{b} [/tex]

[tex]b = log_{e}(0.55) = - 0.5978[/tex]

b≈(-0.6)

[tex]y = 37000 {e}^{ - 0.6t} [/tex]

is the required equation

ii)

[tex]y = 37000 {e}^{ - 0.6 \times 0.4} [/tex]

[tex]y = 37000 {e}^{ - 0.24} [/tex]

iii) it decreases by a factor of

[tex] {e}^{0.6} [/tex]

every decade

So the factor by which the price of car decreases every year is

[tex] {e}^{ \frac{0.6}{10} } [/tex]

as 1year =1/10 decade

Hence the required factor

[tex] {e}^{0.06} [/tex]

Resolviendo un par de ecuaciones lineales veremos que pedro tiene 400 pesos.

Sabemos que:

María tiene 900 pesos.

Juan tiene el doble de la tercera parte de María, entonces:

J = (2/3)*$900 = $600

Juan tiene 600 pesos.

Finalmente, sabemos que la suma del dinero de Pedro y Juan es de $1,000 pesos, entonces tenemos que resolver la ecuación lineal:

P + J = $1,000

P + $600 = $1,000

P = $1,000 - $600 = $400

Pedro tiene 400 pesos.

Answer:

171 Square Feet

Step-by-step explanation:

We first cut the figure up into smaller parts...

we then use the formula (L x W = A) to find the area

L = Lenth

W = Width

the first rectangle (1)...

15 x 5 = 75

the second figure (2)...

8 x 9 = 72

the third figure (3)...

6 x 4 = 24

now we have to add up all the values to find the area of the entire figure...

75 + 72 + 24 = 171

Once the apartment complex have been turned to a parking area, the total parking area will be 1620 square units

From the complete question, the parking area consists of the following shapes and dimensions

The area of a rectangle is the product of its dimensions.

So, the area of the parking area is:

Area = 28x40 + 20x25

Evaluate the products

Area = 1120 + 500

Evaluate the sum

Area = 1620

Answer:

pattern P: 8,13,23,43,83

pattern Q: 6,10,18,34,66

The tables that contain the first 5 elements of both patterns are:

For pattern P we start at 8, and to get the next element we multiply by 2, and then subtract 3.

So the first 5 elements are:

[tex]a_1 = 8\\\\a_2 = 2*8 - 3 = 13\\\\a_3 = 2*13 - 3 = 23\\\\a_4 = 2*23 - 3 = 43\\\\a_5 = 2*43 - 3 = 83[/tex]

For pattern Q we start at 6, and then we subtract 2 and multiply by 2 to get the next element.

[tex]b_1 = 6\\\\b_2 = (6 - 2)*2 = 8\\\\b_3 = (8 - 2)*2 = 12\\\\b_4 = (12 - 2)*2 = 20\\\\b_5 = (20 - 2)*2 = 36\\\\[/tex]

Answer: 10 Inches

Step-by-step explanation:

The solution of the equation is approximately x = 4 and there are no other solutions

The equation is given as

0.1(2^x) = 4/x

Also, we have the table of values as one of the given parameters

Next, we check the table of values

From the table of values, we can see that:

The value of x is between x = 3 and x = 4

This is so because the values of the expressions 0.1(2^x) and 4/x are closest at these values

However, the value of x is closer to 4 than 3

This means that

x = 4 (approximately)

Hence, the solution of the equation is approximately x = 4 and there are no other solutions
