The significant digits include all non-zero numbers (8 and 9) and the zeros between them (the five zeros).

Hence it has 8 significant digits.

There are nine significant digits in 80,000,089.

In the number 80,000,089, there are nine significant digits. Significant digits are the digits in a number that carry meaning or contribute to its precision. They do not include leading or trailing zeros that serve as placeholders.

In this case, the significant digits are "8," "0," "0," "0," "0," "0," "8," and "9." Each of these digits contributes to the value and precision of the number. The leading "8" is significant as it represents the tens of millions place, while the trailing "9" represents the units place.

Zeros that appear between nonzero digits, as in "80,000,089," are considered significant because they indicate the magnitude of the number.

However, zeros that appear before the first nonzero digit, such as in "000,000,089," are not considered significant since they only serve as placeholders and do not affect the value or precision of the number.

Therefore, in the number 80,000,089, there are nine significant digits.

Answer:

Each equation should be matched to its number of solutions as follows;

–2(3x – 1) = –6x – 1  ⇒ no solution.

2(3x – 1) = 6x – 2      ⇒ infinitely many solutions.

2(3x – 1) = –6x – 2    ⇒ one solution.

In Mathematics, an equation is said to have an infinitely many solution when the left hand side and right hand side of the equation are the same or equal.

This ultimately implies that, an equation would have infinitely many solutions when both sides of the equal sign are the same, and both the slope and intercept for the two lines are the same.

In Mathematics, no solution is also referred to as zero solution, and an equation is said to have no solution when the left hand side and right hand side of the equation are not the same or equal.

Next, we would evaluate each of the given equations as follows;

-2(3x - 1) = -6x - 1

-6x + 2 = -6x - 1

-6x + 6x = -1 - 2

0x = -3 (no solution)

2(3x - 1) = 6x - 2

6x - 2 = 6x - 2 (infinitely many solutions)

2(3x - 1) = -6x - 2

6x - 2 = -6x - 2

6x + 6x = -2 + 2

12x = 0 (one solution).

Step-by-step explanation:

The formula that expresses the number of teachers in the school, ne, in terms of the number of students in the school, T, is:

ne = T / 11

Based on the given information that for each teacher there are 11 students, we can write a formula to express the number of teachers in the school, ne, in terms of the number of students in the school, T.

Since the ratio of teachers to students is 1:11, we can set up the following equation:

ne / T = 1 / 11

To find the number of teachers, ne, we can rearrange the equation:

ne = (1 / 11) T

Therefore, the formula that expresses the number of teachers in the school, ne, in terms of the number of students in the school, T, is:

ne = T / 11

You subtract the retail price from the original and you divide the number you get by the original price and then times the number by a hundred.

We can simplify the expression as follows:

p/(p² - 7) ÷ p²/(p² - 49)

= p/(p² - 7) * (p² - 49)/p² (by flipping the second fraction and multiplying)

= p(p + 7)(p - 7)/(p² - 7)(p²)

= (p + 7)(p - 7)/(p²)

Now, we can write this expression in the form of a + b/p as follows:

(p + 7)(p - 7)/(p²) = (p² - 49 + 2 * 49p)/(p²)

= 1 - 49/p² + 98/p³

Therefore, we can write the expression as:

p/(p² - 7) ÷ p²/(p² - 49) = (p + 7)(p - 7)/(p²) = 1 - 49/p² + 98/p³

So, we have expressed the given expression in the desired form of a + b/p where a = 1 and b = 0 and they are both integers.

Amount of interest on loan at Rimrock Bank, using ordinary interest at a rate of 15%, is $48,750 and at rate of 14.5%, is $47,125. In Southside National Bank , interest at a rate of 15%, is $49,500.

To compete with Rimrock Bank's offer, Southside National Bank would need to quote a rate of 14.38% using exact interest.                                    (a) To calculate the amount of interest on the loan at Rimrock Bank, we use the formula I = PRT, where I is the interest, P is the principal amount, R is the interest rate, and T is the time in years. Plugging in the values, we have I = $1,300,000 * 0.15 * (90/365) = $48,750.

(b) The amount of interest on the loan at Southside National Bank using exact interest is calculated the same way as in part (a), resulting in I = $1,300,000 * 0.15 * (90/360) = $49,500.                                                        (c) Similarly, using the same formula, we find the interest on the loan at Rimrock Bank with a rate of 14.5% to be I = $1,300,000 * 0.145 * (90/365) = $47,125.

(d) To determine the rate at which Southside National Bank should quote to compete with Rimrock Bank's last offer, we subtract the given interest difference of $1,125 from the interest calculated in part (b). Solving for R, we have $48,750 - $1,125 = $1,300,000 * R * (90/360). Solving this equation results in R ≈ 0.1438, which is 14.38% rounded to the nearest hundredth of a percent.

Step-by-step explanation:

Got this right on edge.

We have shown that for every whole number n, there exists a value of x in the interval (2n−1)π/2 < x < (2n+1)π/2 such that tan(x) = x.

To prove that there exists a value of x such that tan(x) = x for each whole number n, we can use the Intermediate Value Theorem.

The Intermediate Value Theorem states that if a continuous function takes on two different values at two different points in an interval, then it must also take on every value between those two points at some point within the interval.

In this case, we consider the function f(x) = tan(x) - x. We want to show that there exists a value of x in the [(2n-1)π/2, (2n+1)π/2] where f(x) = 0, which means tan(x) = x.

First, we note that f(x) is continuous within the given interval since both tan(x) and x are continuous functions.

Next, we evaluate f((2n-1)π/2) and f((2n+1)π/2):
f((2n-1)π/2) = tan((2n-1)π/2) - (2n-1)π/2 = -∞ - (2n-1)π/2 < 0
f((2n+1)π/2) = tan((2n+1)π/2) - (2n+1)π/2 = ∞ - (2n+1)π/2 > 0

Since f((2n-1)π/2) < 0 and f((2n+1)π/2) > 0, by the Intermediate Value Theorem, there must exist a value of x in the integral  [(2n-1)π/2, (2n+1)π/2] such that f(x) = 0. This means there exists an x such that tan(x) = x for each whole number n.

Therefore, we have shown that for every whole number n, there exists a value of x in the interval (2n−1)π/2 < x < (2n+1)π/2 such that tan(x) = x.

Answer:

\(m=\frac{-5}{3}\)

Step-by-step explanation:

We want to find the slope between the points (-2,5) and (1,0).

The slope (m) can be found using the formula \(\frac{y_2-y_1}{x_2-x_1}\), where \((x_1,y_1)\) and \((x_2,y_2)\) are points.

We are already given the values of the points, but let's label their values to avoid any confusion and mistakes.

\(x_1=-2\\y_1=5\\x_2=1\\y_2=0\)

Now, substitute into the formula.

\(m=\frac{y_2-y_1}{x_2-x_1}\)

\(m=\frac{0-5}{1--2}\)

Simplify this to:

\(m=\frac{0-5}{1+2}\)

\(m=\frac{-5}{3}\)

The slope is -5/3.
