Step-by-step explanation:

If Jack runs 34 miles, and Pranav runs 18 less, this signifies that we need to subtract 18 from Jack's total miles to get his miles ran.

34 - 18 = 16

Pranav ran 16 miles.

Answer:

y = -13x + 4

Step-by-step explanation:

You want to put it in the form y = mx + b where m is the slope and b is the y-intercept (For example, in the equation y = 2x + 3 the slope is 2 and the y-intercept is 3)

Since the slope is -13, m = -13.

Since the y-intercept is 4, b = 4.

This means the equation is y = -13x + 4

Answer:

A function is said to be an even function if its graph is symmetric with respect to the y-axis. For example, the function f graphed below is an even function. Verify this for yourself by dragging the point on the x-axis from right to left. Notice that the graph remains unchanged after a reflection across the y-axis!

The calculated value of p in terms of m is (c) p = ±√m

from the question, we have the following parameters that can be used in our computation:

m/p = r

Multiply through by p

So, we have

m = rp

Divide both sides by r

p = m/r

Also, we have

r = p

Substitute the known values in the above equation, so, we have the following representation

p = m/p

So, we have

m = p²

Take the square root of both sides

p = ±√m

This means that the value of p is p = ±√m

Therefore , the solution of the given problem of function comes out to be after 7 years, the friend's account has a higher amount.

Integers, their subtypes, and arithmetic are all studied in mathematics, along with the region's anatomy, formations, and both real and hypothetical places. A function describes how various variables, each with its own corresponding result, are related to one another. A function is composed of an array of parts that, when combined, result in a distinct output for each input.

Here,

\(\mathrm A = Pe^{(rt)} (rt)\)

where A represents the balance, P represents the original deposit, e represents the base of the natural logarithm, r represents the interest rate (in decimal form), and t represents the passing of time in years.

\(\mathrm A = 3000 * e^{(0.04*7)\)

A ≈ $4,186.06

Consequently, the account will have a sum of roughly $4,186.06 after seven years.

Now, we can apply the quarterly compounding algorithm to the friend's account:

\(= > A = P(1 + r/n)^{(nt)\)

P = $2800, r = 0.052, n = 4 (since interest is added quarterly), and t = 7 are the pertinent values for this issue. With these numbers entered into the formula, we obtain:

\(\Rightarrow A = 2800(1 + 0.052/4)^{(4*7)}\\ A = $4,380.52\)

So, after 7 years, the friend's account has an amount of about $4,380.52.

As a result, after 7 years, the friend's account has a higher amount.

Given:

x= Number of people who provided yes responses= 124

P= The point of estimate of the sample of the population portion taken=?

Now,

P=x/n

P=124/400

P= 124/4×100

P= 32/100

P= 0.32 or 32%

#SPJ4

0.31 or 31% is the point estimate of the proportion of the population that would provide yes responses

Estimate of Proportion: If we divide the random variable, the mean, and the standard deviation by n, we get a normal distribution of proportions with P′, called the estimated proportion, as the random variable. (Recall that a proportion as the number of successes divided by n.)

a simple random sample of 400 individuals provides 124 yes responses

The point estimate of individuals that would provide yes responses is the sample proportion.

n= Total number of random sample of people taken=400

x= Number of people who provided yes responses= 124

P= The point of estimate of the sample of the population portion taken

The sample proportion is calculated by dividing number of yes responses by sample size

p = x/n = 124/400= 0.31 or 31%

Answer:

A.

Step-by-step explanation:

C and D do not create any x² terms when doing the multiplications. so, they are out.

B stands for (a+b)×(a-b) = a² - b².

so, that would give us a "-4" at the end and is not fitting to the "+4" term at the end of the original expression.

that leaves us with A.

let's verify :

(4x+2i)(4x-2i)

it follows the same rule as B :

(a+b)(a-b) = a² - b²

a = 4x

b = 2i

you remember, i = sqrt(-1).

so, we get

(4x)² - (2i)² = 16x² - 4×(sqrt(-1))² = 16x² - 4×(-1) = 16x²+4

Step-by-step explanation:

To find the break-even point, we need to determine the point at which the total revenue equals the total cost. Let's call the number of shirts sold "x".

The total cost includes the initial costs of $1,500 and the cost per shirt of $3x, so the total cost is:

y = 1500 + 3x

The total revenue is the price per shirt of $10 multiplied by the number of shirts sold, so the total revenue is:

y = 10x

To find the break-even point, we need to set the total cost equal to the total revenue and solve for x:

1500 + 3x = 10x

Simplifying this equation, we get:

1500 = 7x

Dividing both sides by 7, we get:

x = 214.29

Therefore, Steve needs to sell 215 shirts to break even.So the correct system to find the break-even point is:

y = 1500 + 3x (total cost)

y = 10x (total revenue)



1. P-adic Numbers:

P-adic numbers are a specialized alternative not commonly used as a continuity strategy in mathematics. They are an extension of the real numbers that provide a different way of measuring and analyzing numbers. P-adic numbers are based on a different concept of distance, known as the p-adic metric. This metric assigns a measure of closeness or distance between numbers based on their divisibility by a prime number, p. P-adic numbers have unique properties and can be useful in number theory, algebraic geometry, and other branches of mathematics. However, they are not typically employed as a continuity strategy in practical applications.

2. Nonstandard Analysis:

Nonstandard analysis is a mathematical framework that provides an alternative approach to calculus and analysis. It introduces new types of numbers called "infinitesimals" and "infinite numbers" that lie between the standard real numbers but are infinitely smaller or larger than any real number. Nonstandard analysis allows for more rigorous treatment of infinitesimal quantities and provides a different perspective on limits, continuity, and differentiation. While nonstandard analysis has theoretical implications and can provide valuable insights in mathematical research, it is not commonly used as a continuity strategy in practical applications where standard analysis and calculus are more prevalent.

Marcus is accurate. Jeremy is wrong because he overlooked the negative sign in the equation's initial addend. Since -25 has a greater absolute value than 3, it is obvious that the sum should be negative.

Marcus is correct; the solution is -22.

The simplified expression is given as:

The right response is this. Marcus saw the bracket or parentheses symbol when he condensed his sentence. This has major significance.

Jeremy scored 28. He squared -5 without noting that it was in a bracket or parenthesis, therefore his response is incorrect.

We have expressed 3/5 + 2/3 as the ratio of two integers, 19 and 15. Since it can be expressed as a ratio of integers, we can conclude that it is rational.

To show that 3/5 + 2/3 is rational, we need to find a way to write it as a ratio of integers. To do this, we first need to find a common denominator for the two fractions. The least common multiple of 5 and 3 is 15, so we can rewrite the fractions as follows:

3/5 = 9/15

2/3 = 10/15

Now we can add the two fractions:

3/5 + 2/3 = 9/15 + 10/15

Combining the numerators, we get:

3/5 + 2/3 = 19/15

Therefore, we have expressed 3/5 + 2/3 as the ratio of two integers, 19 and 15.

The basic function equivalent to the piecewise-defined function f(x) = x if x ≥ 0 and -x if x < 0 is f(x) = |x|, which represents the absolute value of x.

The given piecewise-defined function f(x) has different expressions for different intervals. For x greater than or equal to zero, f(x) takes the value of x. For x less than zero, f(x) is equal to -x. We need to find a basic function that captures this behavior.

Among the options provided, f(x) = |x| is equivalent to the given piecewise function. The absolute value function, denoted by |x|, returns the positive value of x regardless of its sign. When x is non-negative, |x| equals x, and when x is negative, |x| is equal to -x, mirroring the conditions of the piecewise-defined function.

The function f(x) = |x| represents the absolute value of x and matches the behavior of the given piecewise-defined function, making it the equivalent basic function.
