4 lb. 14 oz.

__________

7 lbs. 29 oz.

Since there are 16 oz in one pound, subtract 16 from 29 to get 13 oz and don’t forget to add that pound to the 7, so your final answer should be 8 lbs. 13oz.

Step-by-step explanation:

The percent error of the house of the pizza would be 2.

The difference between the estimated and actual values in comparison to the actual value is expressed as a percentage. In other words, the relative error multiplied by 100 equals the percent error.

Percent errors indicate the magnitude of our errors when measuring something in an analysis process. Lower percentage errors indicate that we are getting close to the accepted or original value.

Suppose the actual value and the estimated values after the measurement are obtained. Then we have:

Error = Actual value - Estimated value

To determine the percent error, we will measure how much percent of the actual value, the error is, in the estimated value.

We have been given that House of Pizza says that their pizzas are 14 inches wide, but when measured, the pizza was 12 inches.

WE know that Error = Actual value - Estimated value

Then Error = 14 - 12 = 2

Therefore, the percent error would be 2.

The population of impalas at t = 3 months is decreasing at a rate of \(-(\frac{\pi}{3})\)  thousand per month, or approximately -1.05 thousand per month.

The derivative is a mathematical concept that represents the rate of change of a function with respect to its input.

To find the population of impalas after 3 months, we can substitute t = 3 into the given function;

\(R(t)=10+2Cos(\pi t/6)\)

\(R(3)=10+2Cos(\pi *3/6)\)

        \(= 10 + 2cos(\pi/2)\)    = 10

Therefore, the population of impalas after 3 months is 10,000 (since R(t) is measured in thousands).

To find the rate of change of the population at t = 3 months, we can take the derivative of the function R(t) with respect to t:

\(R(t)=10+2Cos(\frac{\pi t}{6} )\)

\(R'(t)=-\frac{\pi}{3} Sin (\frac{\pi t}{6} )\)

Substituting t = 3 into the derivative, we get:

\(R'(3)=-\frac{\pi}{3} Sin (\frac{\pi}{2} )\\\)

         \(= -\frac{\pi}{3}\)

Therefore, the population of impalas at t = 3 months is changing at a rate of \(-(\frac{\pi}{3})\)  thousand per month, or approximately -1.05 thousand per month (rounded to 2 decimal places).

Answer:

$131250

Step-by-step explanation:

Talia's earnings during one year are equal to her base yearly salary ($65000) added to her commission. Now, to know the commission it is necessary to find the 2.65% of her total sales ($2.5 million)

Step 1. Divide the total sales or 2,500,000 by 100 considering this represents the total or 100%

2,500,000 ÷ 100 = 25000

Step 2. Multiply this number by the specific percentage (2.65)

25000 x 2.65 = 66250

Now add the commission and the yearly salary

65000 + 66250 = 131250

Hence, total earnings of Talia were $131250

Answer:

the area of the curve y= f(x) = x between x = 5 and x = 10

\(A=\frac{75}{2}\)

Step-by-step explanation:

Using the Area formula

\(A=\int _a^b\:f\left(x\right)dx\)

As the area of curve lies between x = 5 and x = 10

so

so the integral expression becomes

\(A=\int _5^{10}xdx\)

\(\mathrm{Apply\:the\:Power\:Rule}:\quad \int x^adx=\frac{x^{a+1}}{a+1},\:\quad \:a\ne -1\)

\(A=\left[\frac{x^{1+1}}{1+1}\right]^{10}_5\)

    \(=\left[\frac{x^2}{2}\right]^{10}_5\)

     \(=\frac{1}{2}\left[10^2-5^2\right]\)

     \(=\frac{1}{2}\cdot \:75\)

Therefore, area of the curve y= f(x) = x between x = 5 and x = 10

where r = 19 feet, h = 40 feet, and θ varies from 0 to 8π (4 complete revolutions) as t varies from 0 to 4.

An equation is a mathematical statement that shows the equality of two expressions, which are separated by an equals sign (=). An equation can have variables, constants, coefficients, and operators. The variables are represented by letters, and their values can change depending on the context of the problem. The constants are fixed values, and the coefficients are the numbers that multiply the variables. The operators are mathematical symbols that indicate the operation to be performed, such as addition (+), subtraction (-), multiplication (*), division (/), and exponentiation (^). Solving an equation means finding the value(s) of the variable(s) that satisfy the equation.

Given by the question.

Let's start by defining the necessary parameters. The radius of the staircase is given as 19 feet, and the height is given as 40 feet. The staircase makes 4 complete revolutions, so the total height of the staircase is 4 times the height of one revolution, which is 40 feet.

To find a vector parametric equation for the helical path, we need to consider the circular motion around the center axis, as well as the motion along the axis. Let's define the following parameters:

r: radius of the staircase (19 feet)

h: height of one revolution (40 feet)

θ: angle of rotation around the center axis (in radians)

z: height along the center axis

The circular motion around the center axis can be described by the following parametric equation:

x = r cos(θ)

y = r sin(θ)

z =???

To find the equation for z, we need to consider the motion along the center axis. Since it takes one hour to stroll up one revolution, and there are 4 revolutions in total, the time it takes to stroll up the entire staircase is 4 hours. Therefore, we can use t as a parameter that varies from 0 to 4, and define z as:

z = (h/4) t

Note that we divide h by 4 to scale the parameter t to the interval [0,4].

Putting it all together, the vector parametric equation for the helical path is:

r(t) = <r cos(θ), r sin(θ), (h/4) t>

2 raised to the third power is equal to 2^3 = 8.The value of 2 to the 4th power i.e., 2^4 is 16.

What is exponent?

The exponent of a number shows how many times the number is multiplied by itself.

2 to the 3rd power can be written as 2^3 = 2 × 2 × 2, as 2 is multiplied by itself 3 times.

Here, 2 is called the "base" and 3 is called the "exponent" or "power."

In general, xn means that x is multiplied by itself n times.

2^3 = 2 × 2 × 2 = 8

Thus, 2 raised to the third power = 2^3 = 8.

According to the Power Rule of Exponents,

am = a × a × a... m times

Answer:

Step-by-step explanation:

This is a bit of a tricky equation, and it's what we call an exponential equation since it involves some exponents. The way we begin to solve these kinds of problems is make the base on each side of the equals sign the same. On one side, we have 9 as our base, and on the other side, we have 3 as our base. 9 = 3², so we can rewrite our equation as shown below:

(3²)⁴ˣ⁻¹⁰ = 3⁵ˣ⁻²

From there, we can use the exponent rule (xᵃ)ᵇ = xᵃᵇ to simplify the left side of the equation.

3²⁽⁴ˣ⁻¹⁰⁾ = 3⁵ˣ⁻²

3⁸ˣ⁻²⁰ = 3⁵ˣ⁻²

Since our bases are now the same, we can take just the exponents and turn it into a new equation as shown below:

8x - 20 = 5x - 2

Hopefully at this point, this problem becomes easy for you, but I'll show how I solved this new equation below in case it doesn't make sense.

8x - 20 = 5x - 2

8x - 20 - 5x = 5x - 2 - 5x

3x - 20 = -2

3x - 20 + 20 = -2 + 20

3x = 18

3x/3 = 18/3

x = 6
