Answers

Answer 1

Answer

a) The plotted graph is shown in the Explanation below.

b) a = 12, b = 2

Explanation

n = a(b^m)

Taking the logarithm of both sides

log n = log [a(b^m)]

log n = log a + log (b^m)

log n = log a + m log b

So, to first plot the graph, we know we need to rewrite this equation to match the equation of a straight line. Equation of a straight line is

y = mx + b

where

y = y-coordinate of a point on the line.

m = slope of the line.

x = x-coordinate of the point on the line whose y-coordinate is y.

b = y-intercept of the line.

log n = (log b) m + log a

y = mx + b

y-axis = log n

slope = log b

x-axis = m

intercept = log a

So, we need to plot log n (on the y-axis) against m (on the x-axis)

m | n | log n

1 | 24 | 1.38

2 | 48 | 1.68

3 | 96 | 1.98

4 | 192 | 2.28

5 | 384 | 2.58

The values for log n are then plotted against the corresponding value of m

The image is presented below.

From the graph, we can easily see that

Intercept = 1

To obtain the slope, for a straight line, the slope of the line can be obtained when the coordinates of two points on the line are known. If the coordinates are (x₁, y₁) and (x₂, y₂), the slope is given as

Using the two farthest points,

(x₁, y₁) and (x₂, y₂) = (1, 1.38) and (5, 2.58)

[tex]\begin{gathered} Slope=m=\frac{Change\text{ in y}}{Change\text{ in x}}=\frac{y_2-y_1}{x_2-x_1} \\ \text{Slope = }\frac{2.58-1.38}{5-1}=\frac{1.2}{4}=0.3 \end{gathered}[/tex]

b) Intercept = log a = 1.08

a = log⁻¹ (1.08) = 12

Slope = log b = 0.3

b = log⁻¹ (0.3) = 1.995 = 2

n = 12 (2^m)

We can test this by putting values of m in the expression looking to get n

when m = 1,

n = 12 (2^1)

n = 12 (2) = 24

when m = 5

n = 12 (2^5)

n = 12 (32) = 384

So, our model works!!!

Hope this Helps!!!

Adrian's favorite hobby is to take underwater pictures of his favorite sea creatures. Adrian decides to dive 48 feet below sea level so he can take pictures of seahorses that are 55 feet below sea level. What is the total distance
between him and the seahorses?

Answers

The total distance between Adrian and the seahorses is 7 feet.

How to calculate distance between two planes below sea level?
Since, the values of distances of the planes from the sea level are given as reference, mere linear subtraction of the smaller value from the larger value will bring in the distance between the seahorses and Adrian constructively; if the value turns out to be negative for unforeseen reasons, the modulus of the value obtained will serve the purpose.

Given, the distance from sea level where seahorses dwell = d₁ = 55 feet
The distance from sea level Adrian would dive = d₂ = 48 feet
Distance between seahorses and Adrian = d₁ - d₂ = (55 - 48) feet = 7 feet
Thus, the total distance between Adrian and the seahorses is 7 feet.

Study Surface Area and Volume of Pyramid and Cone. How to find lateral area and total surface area of pyramid? please include one(1) problem per question with solutions.

Answers

Let's apply the formula for the lateral area and total surface area of a pyramid.

• Lateral Surface Area:

To find the lateral area of a pyramid, apply the formula:

[tex]A_l=\frac{1}{2}ps[/tex]

Where:

p is the perimeter of the base

s is the slant height.

Example:

From the above square base pyramid, we have:

length of base, b = 4 cm

Slant height, s = 3 cm

Let's find the lateral area.

Since the base is a square, the perimeter will be:

p = 4 x 4 = 16 cm

Hence, to find the lateral area, we have:

[tex]\begin{gathered} A_l=\frac{1}{2}ps \\ \\ A_l=\frac{1}{2}\times16\times3 \\ \\ A_l=24\operatorname{cm}^2 \end{gathered}[/tex]

Therefore, the lateral area of the square base pyramid above is 24 cm².

• Total surface area of a pyramid.

To find the total surface area of a pyramid, apply the formula:

[tex]A_s=\frac{1}{2}Ps+A[/tex]

Where:

A is the area of the base

p is the perimeter of the base

s is the slant height.

Or we can simply say, the formula for total surface area is:

Total surface area = Lateral area + Area of base

Example:

Using the squarea base pyramid above, we have:

Area of base = 4 x 4 = 16 cm²

Lateral area = 24 cm²

Total surface area = 24 cm² + 16 cm² = 40 cm².

The linear equation y = 1.25x + 9.5 can be used to determine the cost for anyone who only pays for ride tickets and fair admission.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Spencer bought 17 tickets for the rides and spent a total of $30.75 at a county fair.

Let x be the number of tickets and y be the total cost:

Total ticket cost = 17×1.25 = $21.25

Admission fari = 30.75 - 21.25 = $9.5

The linear equation is:

y = 1.25x + 9.5

[tex]\begin{gathered} 3x=8y-3 \\ x=\frac{8y-3}{3} \end{gathered}[/tex]

Then,

[tex]\begin{gathered} 4y+2x=5 \\ 4y+2(\frac{8y-3}{3})=5 \\ 4y+\frac{16y-6}{3}=5 \\ 4y+\frac{16}{3}y-2=5 \\ \frac{12y+16y}{3}=5+2 \\ \frac{28y}{3}=7 \\ 28y=7\cdot3 \\ y=\frac{21}{28} \\ y=\frac{3}{4} \end{gathered}[/tex]

So, y = 21/28.

Now, we use the y-value to find x.

[tex]\begin{gathered} x=\frac{8\cdot\frac{21}{28}-3}{3}=\frac{\frac{168}{28}-3}{3}=\frac{\frac{84}{14}-3}{3}=\frac{\frac{42}{7}-3}{3} \\ x=\frac{\frac{42-21}{7}}{3}=\frac{\frac{21}{7}}{3}=\frac{3}{3}=1 \end{gathered}[/tex]Hence, the value of each variable is x = 1 and y = 3/4.

The Morgans bought a $333,000 condominium. They made a down payment of $47,000 and took out a mortgage for the rest. Over the course of 30 years theymade monthly payments of $1714.72 on their mortgage until it was paid off.(a)(b)What was the total amount they ended up paying for the condominium(including the down payment and monthly payments)?$1]How much interest did they pay on the mortgage?I need help with this math problem.

Answers

Given: The following on the purchase of a Condominium

[tex]\begin{gathered} Price(Condominium)=333000 \\ Down-payment=47000 \\ Monthly-payment=1714.72 \\ Time=30years \end{gathered}[/tex]

To Determine: The total amount they ended up paying for the condominium

Solution

Please note that we have 12 months in a year. The total number of months in 30 years would be

[tex]\begin{gathered} 1year=12months \\ 30years=30\times12months \\ 3oyears=360months \end{gathered}[/tex]

Total monthly payments would be

[tex]\begin{gathered} 1month=1714.72 \\ 360months=360\times1714.72=617299.20 \end{gathered}[/tex]

Therefore, the total amount they ended up paying for the condominium would be the addition of the down payment and the monthly payments

[tex]Total-amount(Paid)=47000+617299.20=664299.20[/tex]

Hence, the total amount they ended paying for the condominium is $664,299.20

The interest paid on the mortgage would be the difference between the total amount paid and the cost

[tex]\begin{gathered} Interest=(Total-amount-paid)-Cost(condominium) \\ =664299.2-333000 \\ =331299.20 \end{gathered}[/tex]

Hence, the interest paid on the Mortgage is $331,299.20

Solve the equation:2.5t=20

Answers

In order to solve this equation for t, we just need to divide both sides of the equation by 2.5.

So we have that:

[tex]\begin{gathered} 2.5t=20 \\ \frac{2.5t}{2.5}=\frac{20}{2.5} \\ t=\frac{20}{2.5} \\ t=8 \end{gathered}[/tex]

So the solution for this equation is t = 8.
