The answer is:

The correct answer is:

d. [tex]f(m)=10+0.25*m[/tex]

From the statement we know that he begins at 10 miles away from his house riding at a speed of 0.25 miles per hour (h)

We have that:

[tex]x_{f}=x_{o}+v*t[/tex]

Where,

[tex]x=FinalPosition\\x_{o}=InitialPosition\\v=speed\\t=time[/tex]

Now, using the given information we have that=

[tex]x_{f}=x_{o}+v*t[/tex]

[tex]x_{f}=10miles+0.25mph*m[/tex]

We have that:

[tex]x_{f}=f(m)[/tex]

So,

[tex]f(m)=10miles+0.25mph*m[/tex]

Hence, we have that the correct answer is:

d. [tex]f(m)=10+0.25*m[/tex]

Final answer:

The function that represents Joe's distance from his house after riding for m minutes is f(m) = 10 - 0.25m. Hence, the answer is B.

Explanation:

The correct function to represent the distance Joe is from his house after riding for m minutes is f(m) = 10 - 0.25m. This is because Joe starts 10 miles away from his house and rides towards it, reducing the distance by 0.25 miles every minute.

To form the function, you need to start with the initial distance, which is 10 miles. Since Joe is moving closer to his house, the distance decreases over time. Therefore, for every minute m that Joe rides, he covers 0.25 miles. Thus, the distance from home after m minutes is the initial distance minus the product of the speed and time, which gives us f(m) = 10 - 0.25m.

18 and 35. The numbers whose sum 53 are 18 and 35.

The key to solve this problem is using a system of equations.

There are two numbers whose sum is 53. This number can be represented as x and y. So:

x + y = 53

Three times the smaller number is equal to 19 more than the larger. Let's set x as the smaller number and y the larger number. So:

3x = 19 + y

Clear y in both equations and let's use the equalization method to solve for x:

y = 53 - x and y = 3x - 19

Then,

53 - x = 3x - 19

53 + 19 = 3x + x ---------> 3x + x = 53 + 19 -------> 4x = 72

x = 72/4 = 18

To find y, let's substitute x = 18 in the equation x + y = 53

18 + y = 53 --------> y = 53 - 18

y = 35

Answer:

Area of equilateral triangle = 43.3 units^2

Step-by-step explanation:

An equilateral triangle is a triangle in which all three sides of triangle are equal.

So,Length = 10 units

Area of triangle = [tex]\frac{\sqrt{3} }{4}*(side)^2[/tex]

                           = [tex]\frac{\sqrt{3} }{4}*(10)^2[/tex]

                           = [tex]\frac{\sqrt{3} }{4}*(100)[/tex]

                          = [tex]43.3units^2[/tex]

So, Area of equilateral triangle = 43.3 units^2.

The answer is:

The area of the triangle is equal to  [tex]A=43.30units^{2}[/tex]

To calculate the area of an equilateral triangle, we need to use the following formula:

[tex]A=\frac{s^{2} *\sqrt{3}}{4}[/tex]

Now, we are given an equilateral triangle, so we know that all of its sides are equal to 10 units.

So, calculating the area we have:

[tex]A=\frac{s^{2} *\sqrt{3} }{4}\\\\A=\frac{(10units)^{2} *\sqrt{3} }{4}\\\\A=\frac{100units^{2} *\sqrt{3} }{4}=43.30units^{2}[/tex]

You can see from the graph that the function increases for [tex]x\in (-2,0)\cup (2,\infty)[/tex]

Final answer:

To determine the intervals where the function y = x⁴ - 8x² + 16 is increasing, calculate the first derivative, find its critical points, and analyze the sign changes. The function is increasing on the intervals (-∞, -2), (0, 2), and (2, ∞).

Explanation:

Intervals Where the Function is Increasing

To determine on which intervals the function y = x⁴ - 8x² + 16 is increasing, we need to analyze the function's first derivative. The first derivative, y', indicates the slope of the tangent to the function at any point. When y' > 0, the function is increasing. Let's find the first derivative of the given function:

Take the derivative of the function y with respect to x: y' = 4x³ - 16x.

Set the derivative equal to zero to find critical points: 4x³ - 16x = 0.

Factor out the common term (4x): 4x(x² - 4) = 4x(x + 2)(x - 2) = 0.

Solve for x to find critical points: x = 0, x = -2, and x = 2.

Analyze the sign of y' around these points to determine where the function is increasing and decreasing.

Through analyzing the signs, you will find that the function is increasing on the intervals (-∞, -2), (0, 2), and (2, ∞).

Note that these intervals are determined by looking at the sign changes of the first derivative around the critical points and selecting the intervals where the derivative is positive.

The surface area of the rectangular prism is 376 square inches.

Explanation:

To find the surface area of an object, we need to calculate the sum of the areas of all its faces. Given the dimensions 10 in., 6 in., 8 in., and 7 in., we can assume that these are the lengths of the sides of a rectangular prism. The formula to find the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l, w, and h represent the length, width, and height of the prism, respectively.

Using the given values, we can substitute 10 in. for l, 6 in. for w, and 8 in. for h to find the surface area:

Surface Area = 2(10 in.)(6 in.) + 2(10 in.)(8 in.) + 2(6 in.)(8 in.)

Surface Area = 120 in² + 160 in² + 96 in²

Surface Area = 376 in²

Answer:

$1,123

Step-by-step explanation:

Remember that the profit  or loses of a business is given by the subtraction between the revenue and the expenses. In our case the revenue is sales, so:

[tex]profit=sales-expenses[/tex]

[tex]profit=1222-2345[/tex]

[tex]profit=-1123[/tex]

Since the profit is negatives, the business is losing money.

We can conclude that the store lose $1,123 that month

The store lost $1,123 in the given month, which is calculated by subtracting their total expenses of $2,345 from their total sales of $1,222.

To calculate the amount of money the store lost in a month, we need to subtract the expenses from the sales. The formula to find the loss or profit is Profit (or Loss) = Sales - Expenses.

In this scenario:

When you perform the subtraction: $1,222 - $2,345 = - $1,123.

The store therefore experienced a loss of $1,123 for that month.

The length of side QR is 16 units.

Option C is correct.

Step-by-step explanation:

Given a right angled triangle QPR in which length of sides are

[tex]PQ=8\sqrt3 units[/tex]

[tex]PR=8 units[/tex]

we have to find the length of side QR

As QPR is right angled triangle therefore we apply Pythagoras theorem

[tex](hypotenuse)^2=(Base)^2+(Perpendicular)^2[/tex]

[tex]QR^2=PQ^2+PR^2[/tex]

[tex]QR^2=(8\sqrt3)^2+8^2[/tex]

[tex]QR^2=192+64=256[/tex]

Take square root on both sides

[tex]QR=16 units[/tex]

Hence, the length of side QR is 16 units.

Option C is correct.

Answer:

20 miles with an error margin of  ± 8 miles

Step-by-step explanation:

The margin of error of a result is the range in which an error can vary. To find the margin of error between both distances we have to

28-12 = 16, that is, the variation of the result has a range of 16 miles. So we will look for the midpoint of both distances

(X2-X1)/2+X1=(28-12)/2+12=16/2+12=8+12=20

So from this midpoint the value can vary between 8 points below and 8 points above that would cover the difference of 16 miles that we observed at the beginning

In this way, the correct answer is 20 miles with an error margin of  ± 8 miles
