Use the general slicing method to find the volume of the solid whose base is the triangle with vertices (0,0), (7,0), and (0,7) and whose cross sections perpendicular to the base and parallel to the y-axis are semicircles.
(need exact answer in terms of pi).

Answers

Answer 1

Answer:

The answer is "[tex]\bold{\frac{343 \ \pi}{24} \ \text{cubic units}}[/tex]"

Step-by-step explanation:

The volume of the mass whose cross-sectional area has been perpendicular is usually sliced by the method The cross-section, which is based to parallel to y-axis;  

[tex]V = \int_{a}^{b} A (x)dx[/tex]

The semi-circular segment of the strong and seems to be perpendicular to foundation and  

Y-axis parallel.  

Its cross-section does have a diameter of: [tex](7-x)[/tex].  

It also transverse radius is: [tex]\frac{1}{2}(7-x)[/tex].  

The semi-circular segment area is,

[tex]Formula: \\\\ A(x)=\frac{1}{2} \times \pi \times r^2[/tex]

        [tex]=\frac{1}{2} \times \pi \times (\frac{(7-x)}{2})^2\\\\=\frac{1}{2} \times \pi \times (\frac{(7-x)^2}{4})\\\\=\frac{1}{8}\pi(7-x)^2\\[/tex]

when

[tex]0 \leq \ x \ \leq 7[/tex]

Calculating the volume from the solid accordingly:

[tex]V= \int_{0}^{7}\frac{1}{8} \times\pi \times (7-x)^2 dx[/tex]

   [tex]= \frac{1}{8} \pi \int_{0}^{7}(7-x)^2 dx \\\\= \frac{1}{8} \pi [\frac{(7-3)^3}{-3}]_{0}^{7}\\\\= \frac{\pi}{24} \times [7^3-0]\\\\= \frac{\pi}{24} \times 343\\\\= \frac{343 \pi}{24} \\[/tex]

an investment of $5000 earned $1050 for 1 year. How much will an investment of $9000 earn at the same rate for 1 year?​

Answers

Answer:

Amount earned (New investment) = $1,890

Step-by-step explanation:

Given:

Amount invested = $5,000

Earned = $1,050

New investment = $9,000

Find:

Amount earned (New investment)

Computation:

Amount earned (New investment) = [Earned / Amount invested]New investment

Amount earned (New investment) = [1,050 / 5,000]9,000

Amount earned (New investment) = $1,890

Assume the heights in a male population are normally distributed with mean 70.3 inches and standard deviation 4.1 inches. If a randomly selected male’s height is at the 75th percentile, how tall is he (to the nearest tenth of an inch)?

Answers

Answer:

73.1 inches

Step-by-step explanation:

We solve for this using z score formula.

z-score is z = (x-μ)/σ,

where x is the raw score,

μ is the population mean

σ is the population standard deviation.

x = unknown = randomly selected male's height

μ = 70.3 inches

σ = 4.1 inches

z = is not given but we are given its percentile which is 75

The z score for a 75th percentile = 0.674

Hence,

0.674 = x - 70.3/4.1

Cross Multiply

0.674 × 4.1 = x - 70.3

2.7634 = x - 70.3

x = 70.3 + 2.7634

x = 73.0634 inches

The height of the randomly selected male = 73.0634

Therefore, the height of the randomly selected male to the nearest tenth of an inch is 73.1 inches

Find:
f(x) + g(x)
f(x) *g(x)
f(g(x))
f(x) - g(x)

Answers

Step-by-step explanation:

f(x) = 4x - 1

g(x) = 3x - 2

1) f(x) + g(x) = (4x - 1) + (3x - 2)

= 4x - 1 + 3x - 2

= 4x + 3x -1 - 2 = 7x - 3

2) f(x) * g(x) = (4x - 1) * (3x - 2)

= 12x^2 - 8x - 3x + 2

= 12x^2 -11x + 2

3) f(g(x)) = 4(3x - 2) - 1

= 12x - 8 - 1

= 12x - 9

4) f(x) - g(x) = (4x - 1) - (3x - 2)

= 4x - 1 - 3x + 2

= 4x - 3x - 1 +2

= x + 1

Yolanda will be travelling out of town for business. During her travel, she is scheduled to have 4 dinners, 5 lunches, and 3 breakfasts. Her employer will pay her
for these meals at the following rate:
$21.50 for dinner, $12.15 for lunch, and $5.73 for breakfast.
What is the total amount Yolanda will be paid for these meals?

Answers

Answer:

$163.94

Step-by-step explanation:

4 dinners at $21.50 each

5 lunches at $12.15 each

3 breakfasts at $5.73 each

4 • 21.50 = $86

5 • 12.15 = $60.75

3 • 5.73 = $17.19

86 + 60.75 + 17.19 = 163.94

Answer:

$163.94

Step-by-step explanation:

Dinners

Yolanda will have 4 dinners and each dinner costs $21.50

Multiply 4 and 21.50  

⇒ 4 * 21.50  

⇒ 86 = $86  

Lunches

She will have 5 lunches that each cost $12.15

Multiply 5 and 12.15

⇒ 5*12.15

⇒ 60.75 = $60.75

Breakfasts

Yolanda is going to have 3 breakfasts at $5.73 for each breakfast.

Multiply 3 and 5.73

⇒ 3*5.73

⇒ 17.19 = $17.19

Find the total. Add the cost for dinners, lunches and breakfasts together.

$86 + $60.75 + $17.19

$163.94

Yolanda will be paid $163.94 for the meals.

Given:

m∠1 = (2x + 3) m∠3  =  (6x - 17) x? m∠1?

Solution:

∠1 and ∠3 are vertical angles.

We know the property that vertical angles are equal:

2x + 3 = 6x - 176x - 2x = 3 + 174x = 20x = 5m∠1 = 2*5 + 3 = 13°13 ..................................

Given

m ∠ 2 =  (15a + 8) m ∠ 3 =  (5a - 8)a = ?

Solution

∠2 and ∠3 are supplementary angles.

We know the property that supplementary angles add up to 180°:

15a + 8 + 5a - 8 = 180°20a = 180°a = 180°/20a = 9°

Answer:

11.4

Step-by-step explanation:

So we know that Triangle ACB is similar to Triangle EFD.

This means that their sides are proportional to each other.

We want to find x or side AB. To do so, we can set up a proportion.

The proportional side to AB is ED. Let's also use BC since we know its value. The proportional side to BC is DF. Thus:

[tex]\frac{AB}{ED}=\frac{BC}{DF}[/tex]

Substitute x for AB, 3.8 for Ed, 15 for BC, and 5 for DF. Thus:

[tex]\frac{x}{3.8}=\frac{15}{5}[/tex]

Reduce the right:

[tex]\frac{x}{3.8}=\frac{3}{1}[/tex]

Cross multiply:

So, the value of x is 11.4
