Find the following integrals

The answer is one in seven or (1/7)!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer:

x = -9 and 16

Step-by-step explanation:

1. Separate in two cases:

(a) -2x + 7 = 25          and          (b) -2x + 7 = -25

(a) -2x + 7 = 25  ⇒ subtract 7 from both sides

     -2x = 18 ⇒ divide both sides by -2

      x = -9

(b) -2x + 7 = -25 ⇒ subtract 7 to both sides

    -2x = -32 ⇒ divide both sides by -2

     x = 16

Solutions: x = -9, 16

Using the quotient rule, it is found that the derivative of the function is given as follows:

[tex]f^{\prime}(x) = -\frac{1}{2\sqrt{s}(\sqrt{s}+2)^2}[/tex]

Suppose a quotient function defined as follows:

[tex]f(x) = \frac{g(x)}{h(x)}[/tex]

Then, the derivative is given by:

[tex]f^{\prime}(x) = \frac{g^{\prime}(x)h(x) - h^{\prime}(x)g(x)}{h(x)^2}[/tex]

In this problem, we have that:

Then, since g'(x) = 0, the derivative is given by:

[tex]f^{\prime}(x) = -\frac{1}{2\sqrt{s}(\sqrt{s}+2)^2}[/tex]

A¹=7.7×6.6=50.82(area of rectangle inside)

16.1-7.7=8.4/2=4.2

A²=6.6×4.2=27.72(area of triangles)

A=50.82+27.72=78.54

The values that could represent this data set include 5, 6, 9, 10, 12, 10, 4, 6, and 19.

It should be noted that a mean simply means the average of a set of numbers.

In this case, the values that could represent this data set include 5, 6, 9, 10, 12, 10, 4, 6, and 19. Therefore, the mean will be:

= (5 + 6 + 9 + 10 + 12 + 4 + 6 + 19)/9

= 81/9

= 9

When a 10th basketball player on this team scored 12 points in the last game, the new mean will be:

= (81 + 12)/10

= 93/10

= 9.3

Therefore, there's an increase in mean.

Volume is a three-dimensional scalar quantity. The volume of the right-triangular pyramid is 1.008 m³.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of a right-triangle pyramid is one-third of the product of its base area and its height. Therefore, the volume is,

Volume = (1/3) × 0.5 × 1.4 × 1.8 × 2.4

             = 1.008 m³

Hence, the volume of the right-triangular pyramid is 1.008 m³.

Answer:

144

Step-by-step explanation:

540 degrees is the sum of angles in a pentagon

Divide 540 by 5(number of sides) =108(interior angle)

Since there are two pentagons you do 108 X 2 = 216 degrees

Do 360 - 216 = 144

The set of parallel lines in a quadrilateral leads to the parallelogram.

Any closed figure made by 4 line segments joined end to end in series is called a quadrilateral.

Line M

x - y + 3 = 0,

y = x + 3

m = 1

Line L

y = x - 2,

m = 1

Line N

y = -1/2x + 5,

m = -0.5

Line P

x+2y+12=0

y = -x/2 - 6

m = -0.5

Here we can see that the slope of line M and L are equal and slope of line N and P are equal.

That quadrilateral in which opposite sides are parallel is called a parallelogram.

Hence, the set of parallel lines in a quadrilateral leads to the parallelogram.

Answer:

C

Step-by-step explanation:

since ∠ m ≅ ∠ p , then

9x - 2 = 4x + 18 ( subtract 4x from both sides )

5x - 2 = 18 ( add 2 to both sides )

5x = 20 ( divide both sides by 5 )

x = 4

Add 24 to both sides.

4x = 1024

Divide both sides by 4.

x = 256

2) 7x = 343

Divide both sides by 7.

x = 49

3) x⁴ = 4096

Find 4th root of both sides.

x = 8

Answer:

x > 8

Step-by-step explanation:

14 - 2(x + 1) < - 4 ← distribute parenthesis and simplify left side

14 - 2x - 2 < - 4

12 - 2x < - 4 ( subtract 12 from both sides )

The inequality which is used to find the number of minutes taken by the solution to begin caramelising is 310 < 250 + 5x <338. The correct answer is option A.

The complete question is given below:-

A sugar solution currently measures 250 degrees Fahrenheit. The temperature of the solution increases 5 degrees per minute. The sugar solution will caramelize at temperatures greater than 310 and less than 338 degrees Fahrenheit. Which inequality can be used to find x, the number of minutes it will take for the solution to begin caramelizing? 310 < 250 + 5x < 338 310 < 250 + 5x < 338 310 < 5(x + 250) < 338 310 < 5(x + 250) < 338

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions is called an inequality.

According to the given question.

The current temperature of a sugar solution is 250 degrees Fahrenheit. Per minute the temperature of the solution increases by 5 degrees. Also, x is the number of minutes taken by the sugar to caramelize.

⇒ The total increase in the temperature in x minutes = 25 + 5x

Since the sugar solution caramelizes at a temperature greater than 310 and less than 338.

Inequality will be given as:-

310 < 250 + 5x < 338

Therefore, the inequality which is used to find the number of minutes taken by the solution to begin to caramelize is given by 310 < 250 + 5x < 338.

Answer: 2

Step-by-step explanation:

DE * CE = AE * BE (Two Secants Segment Theorem)

▪︎ DE = 1 + x + 4

▪︎ CE = x + 4

▪︎ AE = 11 + x + 1

▪︎ BE = x + 1

=> (1 + x + 4)(x + 4) = (11 + x + 1)(x + 1)

=> (x + 5)(x+4) = (x + 12)(x + 1)

=> x^2 + 9x + 20 = x^2 + 13x + 12

=> 9x + 20 = 13x + 12

20 - 12 = 13x - 9x

8 = 4x

The 95% confidence interval for the true proportion of first-year students who intend on majoring in liberal arts is option B. 0.62 plus-or-minus 1.96 start root start fraction 0.62 (1 minus 0.62) over 100 end fraction end root .

Confidence interval in statistics is defined as the certain range of values that you estimate for the unknown parameter lies within.

Confidence interval for the population proportion can be calculated as,

p ± z × [tex]\sqrt{\frac{p(1-p)}{n} }[/tex]

Here, p is the sample proportion and n is the sample size.

z value for 95% confidence interval is 1.96.

Here, n = 100,

p = [tex]\frac{62}{100}[/tex] = 0.62

Substituting the values, confidence interval of true proportion is,

0.62 ± 1.96 × [tex]\sqrt{\frac{0.62(1-0.62)}{100} }[/tex]

Hence the 95% confidence interval for the true proportion of first-year students who intend on majoring in liberal arts is 0.62 ± 1.96 × [tex]\sqrt{\frac{0.62(1-0.62)}{100} }[/tex].
