Answer:

So the translation would be 2 units right and 2 units down.

Step-by-step explanation:

First look at how each value for each x and y value changed. The x value 2 went to 4 and the y value 7 went to 5. The x-value changed by 2 and the y value changed by -2. So the translation would be 2 units right (right because it is positive) and 2 units down (down since the -2 is negative).

The given region is bounded by the x-axis (y = 0), the curve y = ln(bx), and the vertical line x = e/b. To calculate the area of this region, we can integrate the difference between the upper and lower curves with respect to x within the given bounds.

First, we find the intersection point of the curves y = ln(bx) and y = 0. Since y = 0 represents the x-axis, we set ln(bx) = 0 and solve for x. This yields bx = 1, and consequently, x = 1/b.

x = 0 to x = 1/b.

The upper curve is y = ln(bx) and the lower curve is y = 0.

Thus, the area can be calculated as the definite integral from 0 to 1/b of ln(bx) dx.

Answer:b

Step-by-step explanation:

In this case, we'll have to carry out several steps to find the solution.

Step 01:

data:

2[p - (4p + 11) + 1] = 2(p + 10)

Step 02:

solve the equation:

2[p - (4p + 11) + 1] = 2(p + 10)

2[p - 4p - 11 + 1] = 2p + 20

2[- 3p - 10] = 2p + 20

-6p - 20 = 2p + 20

-6p - 2p = 20 + 20

-8p = 40

p = 40 / (-8)

p = - 5

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here, the given equation is :

x + y = 8

which passes through point (8,-5)

Let us first find the slope of line m which is parallel to the line x + y = 8 using point-intercept equation of line that is given by :

y = mx + c....(1)

x + y = 8

y = -x + 8

comparing above equation with equation (1) we get

m = -1

Now, the slope of line parallel to line x + y = 8 will have same slope that is m = -1

Now, Let us find the equation of the line using point-slope equation of line :

(y-y₁) = m(x-x₁)

Substituting all the values in above equation to get the equation of line :

(y-(-5)) = -1(x-8)

(y+5) = -x+8

y + 5 = -x +8

y = -x +3

Therefore, the equation of line which passes through point (8,-3) is y = -x +3.

When the wheel weighs 19.5 pounds, this implies that each hub cover weighs approximately 11.08 pounds.

A mathematical equation is a statement that expresses the connection between two or more quantities using symbols like elements, numbers, and mathematical operations. It may also signify a requirement that must be met or an issue that must be resolved. There are numerous ways to express equations in writing, including the algebraic, geometric, logarithmic, and exponential formats. The expression y = mx + b, for instance, depicts a linear connection between variables x and y, with m denoting the line's slope and b its y-intercept. The sine function and the variable x are related in a trigonometric way by the solution sin(x) = 0.5, where sin(x) is the ratio of a right triangle's opposing side's length to its hypotenuse's length.

given

Let's suppose that each hubcap weighs x pounds.

Since there are 6 of the same hubcaps, their combined weight is 6.

The hubcaps and the tire together weigh 86 pounds, according to the issue. Thus, the following solution can be written:

6x + 19.5 = 86

We can begin by removing 19.5 from both sides to find x:

6x = 86 - 19.5

6x = 66.5

Finally, we can identify x by dividing both sides by 6:

x = 11.08

When the wheel weighs 19.5 pounds, this implies that each hub cover weighs approximately 11.08 pounds.

The limit of the given sequence `9n³ + 1` as n approaches infinity is `10`. The given sequence is = 9n³ + 1. We need to determine whether the given sequence converges or diverges. If it converges, then we need to find the limit.

To find whether the sequence converges or diverges, let's take the limit of the given sequence as n approaches infinity, i.e., lim n→∞ an.  lim n→∞ an = lim n→∞ (9n³ + 1) = lim n→∞ 9n³ + lim n→∞ 1.

Since `lim n→∞ 9n³` is of the form `∞•∞•∞` (infinity times infinity), we cannot directly find its limit.

To evaluate this limit, we need to divide the numerator and denominator by the highest power of n that occurs in the denominator, which is n³.

lim n→∞ 9n³` `= lim n→∞ 9` (dividing numerator and denominator by n³).

Thus, `lim n→∞ an` `= lim n→∞ 9n³ + lim n→∞ 1` `= lim n→∞ 9 + lim n→∞ 1` (applying limit laws)`= 9 + 1` (since `lim n→∞ 1 = 1`)`= 10`.

Therefore, the given sequence converges to `10`. Hence, the limit of the given sequence `9n³ + 1` as n approaches infinity is `10`.

Answer:

x = 3 and y = 5

Step-by-step explanation:

Given equations are :

y=5x−10 ..(1)

y=−3x+14 ...(2)

Subtract equation (2) from (1).

y-y = 5x−10-(−3x+14)

0 = 5x-10+3x-14

0= 8x-24

8x = 24

x = 3

Put the value of x in equation (1).

y=5(3)−10

= 15-10

y = 5

So, the values of x and y are 3 and 5 respectively.

The pieces of cloth are beyond the standard at 0.05 level of significance.

We can use a one-sample t-test to determine if the mean length of the 35 pieces of cloth is significantly different from the standard length of 3.25 meters.

The null hypothesis is that the mean length of the cloth pieces is equal to the standard length:

H0: μ = 3.25

The alternative hypothesis is that the mean length of the cloth pieces is greater than the standard length:

Ha: μ > 3.25

We can calculate the test statistic as:

t = (x - μ) / (s / √n)

where x is the sample mean length, μ is the population mean length (3.25 meters), s is the sample standard deviation (0.52 meters), and n is the sample size (35).

Plugging in the values, we get:

t = (3.52 - 3.25) / (0.52 / √35) = 3.81

Using a t-table with 34 degrees of freedom (n-1), and a significance level of 0.05 (one-tailed test), the critical t-value is 1.690.

Since our calculated t-value (3.81) is greater than the critical t-value (1.690), we reject the null hypothesis and conclude that the mean length of the 35 pieces of cloth is significantly greater than the standard length at the 0.05 level of significance.

\(\sqrt[8]{\cfrac{21}{16}}=1 + \cfrac{r}{100}\implies \sqrt[8]{\cfrac{21}{16}}=\cfrac{100+r}{100} \\\\\\ 100\sqrt[8]{\cfrac{21}{16}}=100+r\implies 100\sqrt[8]{\cfrac{21}{16}}-100=r\implies \stackrel{\%}{3.46}\approx r\)

now, with an initial amount of $4800, up to 2007, namely 17 years later, how much will that be with a 3.46% rate?
