Step-by-step explanation:

826 1/25

Answer:1.5 and 24

Step-by-step explanation:

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Answer: (13 + y)/5

Step-by-step explanation:

13+y is used to determine the actual number of jewelry being split, and /5 is to divide the total jewelry among each sister.

Also, pls look at this https://brainly.com/question/11254684

Answer:

Hey there!

The correct answer would be \(\frac{13+y}{5}\) . The total amount of jewelry the grandmas gave was 13+y.  Dividing that evenly among five people would give you the answer.

Answer:

Yes, in order for zero to be the median, there must be 5 negatives, and 5 positives.

Step-by-step explanation:

Investment in Company A by investor = $6100

Investment in Company B by investor = $6480

The decrease in value of the stock of company A is 2%

The decrease in value of the stock of company B is 10%

Value of wealth that investor lost in company A = 6100× 2/100

= 61×2

= $122

The decline in the value of the stock of company B = 6480×10/100

= 648×1/1

= $648

The total decline in the wealth of the investor= 122+648

= $770

The combined wealth of investor in both companies= 6100+6480

= $12580

Percentage of decline in the stock account of investor= 770×100/12580

= 77000/12580

= 6.1%

The total percentage decline in investor's stock account is 6.1%

Answer:

\(a_{n}=45-3n\)

Step-by-step explanation:

Method 1:

Arithmetic sequence is in the form

\(a_{n} =a_{1} +(n-1)d\\\)

d is the common difference, can be found by:

\(d=a_{n}-a_{n-1}=-3\)

Subtituting the \(a_{1}\) and \(d\)

You get:

\(a_{n}=42+(-3)(n-1)=45-3n\)

Method 2 (Mathematical induction):

Assume it is in form \(a_{n}=45-3n\)

Base step: \(a_{1} =45-3(1)=42\)

Inducive hypophesis: \(a_{n}=45-3n\)

GIven: \(a_{n+1} =a_{n}-3\)

\(a_{n+1}=45-3n-3=45-3(n+1)\)

Proved by mathematical induction

\(a_{n}=45-3n\)

Answer:

-3/16 feet a year

Step-by-step explanation:

since we have a whole number 1 (5/16), we can turn this into an improper fraction 16(from the one) +5=21/16, since we know the number of years (7) we can divide 21 by the number of years. 21/7=3. So it went down 3 feet a year. Hope this helped!

Answer:

8.26

Step-by-step explanation:

you can solve this by putting x for blank

x-5.27=2.99

solve for x

x-5.27+5.27=2.99+5.27

x=8.26

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.

b) The correct expression is given as follows: -8.6b + 28.

The expression in the context of this problem is defined as follows:

(-3.78b + 12) - (4.82b - 16).

The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

-3.78b + 12 - 4.82b + 16.

This is the step where Maddie made the first error.

Then, to simplify the expression, we combine the like terms, as follows:

b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

Answer:

\( \boxed{ \bold{ \huge{ \boxed{ \sf{ - \frac{10}{27}}}}}} \)

Step-by-step explanation:

\( \sf{ - 3 \frac{1}{3} \div 9}\)

Convert the mixed number into improper fraction

\( \longrightarrow{ \sf{ - \frac{ 3 \times 3 + 1}{3} \div 9}}\)

\( \longrightarrow{ \sf{ - \frac{ 9 + 1}{3} \div 9}}\)

\( \longrightarrow{ \sf{ - \frac{ 10}{3} \div 9}}\)

Multiply the dividend by the reciprocal of the divisor. Reciprocal of any number or fraction can be obtained by interchanging the position of numerator and denominator

\( \longrightarrow{ \sf{ - \frac{ 10}{3} \times \frac{1}{9}}} \)

To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator

\( \longrightarrow{ \sf{ - \frac{10 \times 1}{3 \times 9}}} \)

\( \longrightarrow{ \sf{ - \frac{10}{27}}} \)

Answer:

Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.

Step-by-step explanation:

The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.

For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.

I've enclosed an attachment for that.

Answer:

$166.16

Step-by-step explanation:

The price of the triple play package without the discount is $150.

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

So the percentage actually means a part per 100.

Discount for the triple play package if you already subscribe to their cell phone service = 12%

Price of the triple play package with discount = $132

Let x be the price of the triple package without discount.

x - (x × 12%) is the discounted price of the package.

x - (12% × x) = 132

x - (12/100 × x) = 132

x - (0.12 x) = 132

0.88x = 132

x = 132 / 0.88

x = 150

Hence the price of the package without discount is $150.
