(-2÷3)^-3 ÷ x = (9÷8)^-2​

Answer:

Ammount of fencing required = perimeter of the rectangular storage.

Perimeter of a rectangle = 2(l+b), where l = length, b = breadth.

so perimeter = 2(40+20) = 2(60) = 120 feet

so fencing required = 120 feet

HOPE IT WAS HELPFUL!

Answer:

[tex]\Huge \boxed{\mathrm{120 \ feet}}[/tex]

Step-by-step explanation:

The length of the rectangular storage is 40 feet.

The width of the rectangular storage is 20 feet.

The length of fencing is needed to fence the entire rectangular storage.

The perimeter of the rectangle is required.

[tex]P=2l+2w \\ \\ \sf P=perimeter \\ l=length \\ w=width[/tex]

[tex]P=2(40)+2(20) \\ \\ P=80+40 \\ \\ P=120[/tex]

120 feet of fencing is needed to fence the rectangular storage.

Answer:

Minimum -1, maximum 1.

At points (3π/4. -1) and  (π/4 , 1)

Step-by-step explanation:

The maximum value for the sine of an angle is 1 and the minimum is -1.

The angle will have values of π/2 and 3π/2 at these points.

As the angle is 2x the angle values will be  π/4 and  3π/4.

Hey there! I'm happy to help!

First, let's multiply the numerators. We will put q+5 in parentheses so we can multiply it by 4q.

4q(q+5)

We use the distributive property to undo the parentheses.

First, we multiply 4q by q.

4q×q=4q²

And we multiply 4q and 5.

4q×5=20q

So, our numerator right now is 4q²+20q.

Now, for the denominators.

2(q+4)

We do 2 by q.

2×q=2q

And 2×4, which is 8.

So, our denominator is 2q+8.

Right now, our fraction is [tex]\frac{4q^2+20}{2q+8}[/tex], and this is your correct answer. However, we can simplify it a bit more. We can divide the 4 by 2, q² by q, and simplify the 20 and the 8.

4/2=2

q²/q=q

20/8=5/2

Now, our final product is (2q+5)/2

But, mark down your answer as [tex]\frac{4q^2+20}{2q+8}[/tex] because that is technically correct.

Step-by-step explanation:

-(7x² + 5x) / (x² + 1) − 5x / (x² − 6)

To add or subtract fractions, you need a common denominator.

The common denominator of these fractions is (x² + 1) (x² − 6).

Multiply the first fraction by (x² − 6) / (x² − 6).

-(7x² + 5x) (x² − 6) / ((x² + 1) (x² − 6))

-(7x⁴ + 5x³ − 42x² − 30x) / ((x² + 1) (x² − 6))

(-7x⁴ − 5x³ + 42x² + 30x) / ((x² + 1) (x² − 6))

Multiply the second fraction by (x² + 1) / (x² + 1).

5x (x² + 1) / ((x² − 6) (x² + 1))

(5x³ + 5x) / ((x² − 6) (x² + 1))

Subtract the fractions.

(-7x⁴ − 5x³ + 42x² + 30x − 5x³ − 5x) / ((x² + 1) (x² − 6))

(-7x⁴ − 10x³ + 42x² + 25x) / ((x² + 1) (x² − 6))

a) The perimeter of question a's shape is 18 units.

b) The answer to question b is 28 ft.

Answer:p= -18

Step-by-step explanation:Let's solve your equation step-by-step.

5/4 P= 4/3 P + 3/2

Step 1: Subtract 4/3p from both sides.

5/4 P - 4/3 P = 4/3 P + 3/2 - 4/3 P

-1/12 P = 3/2

Step 2: Multiply both sides by 12/(-1).

(12/-1) × (-1/12 P) = (12/-1) × (3/2)

P = -18

Answer:

p = - 18

Step-by-step explanation:

5        4          3

--- p =  --- p + ---

4         3         2

5        2²          3

--- p =  --- p + ---

2²         3         2

5p     2² * p       3

---  =  ---------  +  ---

2²          3          2

p = - 18

We need to determinate who doesn't use anything, so first we must know the real number of who are practising: a person can do more things.

For doing this, is better use a three-circles graphic, but we try to do without it.

So

now:

now we must now who do some facility: let's sum all

16 + 22 + 15 + 17 + 12 + 9 + 8 = 99

99/100 practise something

So only 1/100 doesn't use nothing

b. 11.85 plus or minus 0.0588

Step-by-step explanation:

Give the following :

Sample mean (m) = 11.85 oz

Sample standard deviation (s) = 0.18

Confidence interval = 95%

Number of observations (n) = 36

Using the formula:

Mean ± Z95% × (sd/√n)

Z score at 95% confidence interval = 1.96

11.85 ± [1.96 × (0.18/√36)]

11.85 ± [1.96 × (0.18 / 6)]

11.85 ± (1.96 × 0.03)

Step-by-step explanation:

34-11= women

women divided by 34

23/34 is the fraction of women in the class.

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

In another word, the fraction is the division of the two numbers but the division is not wholly complete.

In another word, if we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

Given that,

Total students in the class = 34 students.

Number of students men = 11

Number of students women = 34 - 11 = 23

Now a fraction of 23 from 34 = 23/34

Hence "23/34 is the fraction of women in the class".

Answer:

x = - 3, x = 0, x = 3

Step-by-step explanation:

Given

4x³ = 36x ( subtract 35x from both sides )

4x³ - 36x = 0 ← factor out 4x from each term

4x(x² - 9) = 0

Equate each factor to zero and solve for x

4x = 0 ⇒ x = 0

x² - 9 = 0 ⇒ x² = 9 ⇒ x = ± [tex]\sqrt{9}[/tex] = ± 3

Answer:

4x^3=36x.

4x^3-36x=0.

4x^3=36x.

4x(x^2-9)=0.

4x=0,x^2-9=0.

x=0,x^2=9.

Answer:  y = 7cos(0.4π x) - 3

Step-by-step explanation:

The equation of a cosine function is:    y = A cos(Bx - C) + D    where

Midline (D) = -3

(-1.25, -3) is given as a point on the midline.  We only need the y-value.

Horizontal stretch (B) = 0.4π

The max is located at (0,4) and also at (5, 4).  Thus the period (length of one wave) is 5 units.

[tex]P=\dfrac{2\pi}{B}\qquad \rightarrow \qquad 5=\dfrac{2\pi}{B}\qquad \rightarrow \qquad B=\dfrac{2}{5}\pi[/tex]          →     B = 0.4π

Phase Shift (C) = 0

The max is on the y-axis so there is no horizontal shift.

Amplitude (A) = 7

The distance from the midline to the max is: A = 4 - (-3) = 7

Equation

Input A = 7, B = 0.4π, C = 0, and D = -3 into the cosine equation.

            y = A cos(Bx - C) + D

            y = 7cos(0.4π x - 0) - 3

            y = 7cos(0.4π x) - 3

Adjacent angles are angles that come out of the same vertex.

Answer:

[tex]\Huge \boxed{x=0}[/tex]

Step-by-step explanation:

Angles on a straight line add up to 180 degrees.

y + 50 = 180

y = 180 - 50 = 130

We can use Angle formed by a chord and tangent theorem to solve for x.

The angle formed by a chord and tangent is half the measure of the intercepted arc.

130 = 1/2(2x+260)

Expand brackets.

130 = x+130

Subtract 130 from both sides.

x = 0

Answer:

(A) 0.0244

(B) 1 (not 1.47 as is calculated) since probability values are between 0 and 1; 0 and 1 inclusive

Step-by-step explanation:

The rare mutation only occurs in 1 generation, out of every 2048 generations. This implies that the next occurrence will fall in or within the next 2048 generations (2 generations in 4096 generations, will have the rare mutation).

(A) The probability of occurrence of this mutation at least once (at most infinity) in 50 generations of fruit flies will surely be less than, as 50 is less than 2048.

The accurate probability is gotten when 50 is divided by 2048

50÷2048 = 0.0244

(B) The probability of seeing this mutation at least once (at most infinity) in 3000 generations would have been 1.47 but for 3 reasons;

- The full question already tells that the mutation will occur once in every 2048 generations and 3000 is greater than 2048, hence there will be a sure occurrence within 3000 generations.

- Question (b) asks you to calculate the probability of seeing this mutation at least once in 3000 generations so, the probability is 1 (representing full probability).

- In probability theory or statistics, all probability values fall within 0 and 1; with 0 representing no occurrence at all and 1 representing full occurrence.

Answer:

Area = 13.15 square units

Step-by-step explanation:

Let the given vertices be represented as follows:

A(2, -1, 1) = 2i - j + k

B(5, 1, 4) = 5i + j + 4k

C(0, 1, 1) = 0i + j + k

D(3, 3, 4) = 3i + 3j + 4k

(i) Let's calculate the vectors of all the sides:

[tex]\\[/tex]AB = B - A =  (5i + j + 4k) - (2i - j + k)

AB = 5i + j + 4k - 2i + j - k                 [Collect like terms]

AB = 3i + 2j + 3k

BC = C - B =  (0i + j + k) - (5i + j + 4k)

BC = 0i + j + k - 5i - j - 4k                 [Collect like terms]

BC = -5i + 0j - 3k

CD = D - C =  (3i + 3j + 4k) - (0i + j + k)

CD = 3i + 3j + 4k - 0i - j - k                [Collect like terms]

CD = 3i + 2j + 3k

DA = A - D =  (2i - j + k) - (3i + 3j + 4k)

DA = 2i - j + k - 3i - 3j - 4k                [Collect like terms]

DA = -i - 4j - 3k

AC = C - A =  (0i + j + k) - (2i - j + k)

AC = 0i + j + k - 2i + j - k                [Collect like terms]

AC = -2i + 2j

BD = D - B = (3i + 3j + 4k) - (5i + j + 4k)

BD = 3i + 3j + 4k - 5i - j - 4k                [Collect like terms]

BD = -2i + 2j

(ii) From the results in (i) above, we can deduce that;

AB = CD This implies that AB || CD  [AB is parallel to CD]

AC = BD This implies that AC || BD  [AC is parallel to BD]

(iii) Therefore, ABDC is a parallelogram since opposite sides (AB and CD) are parallel. Hence, the points are vertices of a parallelogram

Now let's calculate the area

To find the area of the parallelogram, we find the magnitude of the cross product of any two adjacent sides.

In this case, we'll choose AB and AC

Area = |AB X AC|

Where;

[tex]AB X AC = \left[\begin{array}{ccc}i&j&k\\3&2&3\\-2&2&0\end{array}\right][/tex]

AB X AC = i(0 - 6) - j(0 + 6) + k(6 + 4)

AB X AC = - 6i - 6j + 10k

|AB X AC| = [tex]\sqrt{(-6)^2 + (-6)^2 + (10)^2}[/tex]

|AB X AC| = [tex]\sqrt{172}[/tex]

|AB X AC| = 13.15

Area = 13.15 square units.

PS: ACBD is also a parallelogram. The diagram has also been attached to this response.
