Answer:

x^3 - 13x^2.

Step-by-step explanation:

–(5x3 + x2) + 4(x3 – 3x2)  Removing the brackets:-

= -5x^3 - x^2 + 4x^3 - 12x^2

= -5x^3 + 4x^3 - x^2 - 12x^2

= x^3 - 13x^2.

Answer:

Step-by-step explanation:

-(5x³+x²)+4(x³-3x²)

=-5x³-x²+4x³-12x²

=-x³-13x²

Answer:

\(x<12\)

Step-by-step explanation:

\(5(x+5)<85\\\\5x+25<85\\\\5x<60\\\\x<12\)

Option A is correct, x<12 represents the solution set of 5(x+5) <85

a relationship between two expressions or values that are not equal to each other is called 'inequality.

The given inequality is 5(x+5) <85

We have to find the solution set of the given inequality

Five times of x plus five less than eight five.

Apply distributive property

5x+25<85

Subtract 25 from both sides

5x<85-25

5x<60

Divide both sides by 5

x<12

Hence, option A is correct, x<12 represents the solution set of 5(x+5) <85

The amount paid in cash is R2250 and the total amount he paid for the scooter is R17550.

Cost price = R15000

Amount paid = 15% × R15000 = R2250

Therefore, the interest on the remaining amount will be:

= (12750 × 10 × 2)/100

= 2550

The total cost will be:

= 15000 + 2550

= 17550

Step-by-step explanation:

\( \frac{1}{a + b} \times ( \frac{a + b}{ab}) = \frac{1}{ab} \)

Answer with step-by-step explanation:

\((a+b)^-^1*(a^-^1+b^-^1)=(ab)^-^1\)

First, convert these into positive indices.

\(\frac{1}{(a+b)} *(\frac{1}{a} +\frac{1}{b})=\frac{1}{ab}\)

And now, let us solve the left side.

\(\frac{1}{(a+b)} *(\frac{1}{a} +\frac{1}{b})\\\\\)

First, solve the brackets. That is add the fractions inside the brackets.

\(\frac{1}{(a+b)} *(\frac{1}{a} +\frac{1}{b})\\\\\frac{1}{(a+b)}*(\frac{1*b}{a*b} +\frac{1*a}{b*a})\\\\\frac{1}{(a+b)}*(\frac{b}{ab} +\frac{a}{ab})\\\\\frac{1}{(a+b)}*\frac{(a+b)}{ab}\)

Now multiply the fractions.

\(\frac{1}{ab}\)

So, it's clear that the left side equals the right side.

Left side = Right side

\(\frac{1}{ab}=\frac{1}{ab}\)

∴ \((a+b)^-^1*(a^-^1+b^-^1)=(ab)^-^1\)

The Kutta-Joukowski theorem, which is represented by equation (3.140), was originally derived for the case of a lifting cylinder. However, it can also be applied to a two-dimensional body of arbitrary shape, as stated in section 3.16.

A more detailed explanation of the answer.
To make a physical argument for this generalization, we can draw a closed curve around the body.

The key is to draw the curve far enough away from the body such that the body appears as a very small speck in the middle of the domain enclosed by the closed curve.

By doing this, we are essentially treating the body as a point object at the center of the curve. Since the body is now a very small speck in comparison to the large domain, its specific shape becomes insignificant to the overall flow around it.

Therefore, the lifting force calculations derived from the Kutta-Joukowski theorem for the lifting cylinder should also apply to the two-dimensional body of arbitrary shape, as long as the body is small in comparison to the domain enclosed by the closed curve.

This physical argument allows us to accept that equation (3.140) can be applied in general to a two-dimensional body of arbitrary shape without requiring a mathematical proof.

Answer:

x = 10

Step-by-step explanation:

Hey there!

To solve this question we will use PEMDAS (order of operations)

4x−7=8x+33

Subtract 8x from both sides.

4x−7−8x=33

Combine 4x and −8x to get −4x.

−4x−7=33

Add 7 to both sides.

−4x=33+7

Add 33 and 7 to get 40.

−4x=40

Divide both sides by −4.

x= 40/-4

Divide 40 by −4 to get −10.

Answer:

Salary of state A's governor = $170,465

Salary of state B's governor = $118,145

Step-by-step explanation:

We will need a system of equations to find the salaries of each governor.

Let A represent the salary of state A's governor and B represent the salary of state B's governor.

Step 1:  Write an equation showing that state A's governor's salary is $52320 higher than state B's governor:

Since the governor of state A earns $52320 more than the governor of state B, we can model this with the equation:

A  = B + 52320

Step 2:  Write an equations showing that the sum of the two governor's salaries is $288610:

The equation modeling the sum of the governor's salaries is given by:

A + B = 288610

Step 3:  Plug in A = B + 52320 for A in A + B = 288610 to solve for B:

Now, we can plug in A = B + 52320 for A in A + B = 288610 to solve for B:

B + 52320 + B = 288610

Combining like terms gives us:

2B + 52320 = 288610

Subtracting 52320 from both sides gives us:

2B = 236290

Dividing both sides by 2 gives us:

B = 118145

Step 4:  Find A, the salary of state A's governor:

We can plug in 118145 for B in A + B = 288610 to find A, the salary of state A's governor:

A + 118145 = 288610

Subtracting 118145 from both sides gives us:

A = 170465

Thus, the salary of state A's governor is $170,465 and the salary of state B's governor is $118,145.

Answer:

w= -2

Step-by-step explanation:

3w + 2 = 8 + 6w

Subtract 3w from each side

3w-3w + 2 = 8 + 6w-3w

2 = 8+3w

Subtract 8 from each side

2-8 = 8-8+3w

-6 = 3w

Divide each side by 3

-6/3 = 3w/3

-2 =w

Answer:

option 4

Step-by-step explanation:

Given

f(x) = x² - 5x - 6

To find the zeros let f(x) = 0 , that is

x² - 5x - 6 = 0

Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (- 5)

The factors are - 6 and+ 1, since

- 6 × 1 = - 6 and - 6 + 1 = - 5 , then

(x - 6)(x + 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x - 6 = 0 ⇒ x = 6

Answer:

the radius of the water bottle is approximately 2.49 cm.

Step-by-step explanation:

We can use the formula for the volume of a cylinder to find the radius of the water bottle:

V = πr²h

where V is the volume, r is the radius, and h is the height.

Substituting the given values, we get:

165 cm³ = πr²(8.3 cm)

Simplifying, we get:

r² = 165 cm³ / (π × 8.3 cm)

r² = 6.211 cm

Taking the square root of both sides, we get:

r ≈ 2.49 cm

The evaluated probabilities for the given question are 0.20 for the men who asked for promotion, 0.59 for the men who received the promotion when asked, and  0.118 for men who asked for promotion and received.under the condition that from the men interviewed  20% had asked for a promotion and 59% of the men who had asked for a promotion and  received.
Then,
P(man asked for a promotion)
= 20/100
= 0.20

P(man received promotion, given he asked for one)
= 59/100
= 0.59

P(man asked for promotion and received )
= P(man asked for a promotion) x P(man received promotion, given he asked for one)

The formula which shows how to calculate the number of tires, t, needed if they produce c cars per day is t = 5c. option D

Total tires needed by each car = 4 + 1

Total number of tires, t needed for c cars.

Number of tires needed, t = Total tires needed by each car × Number of cars produced per day

t = 5 × c

t = 5c

For instance,

if 5 cars are produced per day

Number of tires needed, t = Total tires needed by each car × Number of cars produced per day

t = 5c

= 5 × 5

In this case, Christopher divides the athletes into groups of varsity and junior varsity, which creates the strata. The type of sampling used in this scenario is stratified sampling.

Stratified sampling is a sampling method where the population is divided into homogeneous subgroups or strata, and individuals are randomly selected from each stratum in proportion to their representation in the population. In this case, Christopher divides the athletes into groups of varsity and junior varsity, which creates the strata.

By randomly selecting a proportionate number of individuals from each group, Christopher ensures that both varsity and junior varsity athletes are represented in the sample, maintaining the proportional representation of each group in the population. This method allows for more accurate and representative results by capturing the characteristics of both groups separately.
