Answer:

33.3%

Step-by-step explanation:

Step one:

given data

Initial population (1980)= 12000

Final population(1990)= 16000

change in population= 16000-12000= 4000

Step two:

% increase= change in population/initail population *100

%increase= 4000/12000*100

%increase= 0.333*100

% increase= 33.3%

Answer:

Shifting down.

Vertically compressed

Step-by-step explanation:

Given

[tex]f(x) = 2^x[/tex]

[tex]g(x) = \frac{1}{3}(2^x - 7)[/tex]

Required

Determine the translation from f(x) to g(x)

The first translation from f(x) towards g(x) is:

[tex]f(x) = 2^x[/tex]

[tex]f'(x) = 2^x - 7[/tex]

This is derived by:

[tex]f'(x) = f(x) - b[/tex]

Where

[tex]b = 7[/tex]

Notice that, in the above, b (i.e. 7) was subtracted from f(x), this implies that the function shifted down

The next translation that resulted in g(x) is:

[tex]g(x) = \frac{1}{3}(2^x - 7)[/tex]

This is derived by:

[tex]g(x) = a.f'(x)[/tex]

By comparison:

[tex]a = \frac{1}{3}[/tex]

Since the value of a is less than 1, then f'(x) is vertically compressed to give g(x).

Hence, the transformations that apply from f(x) to g(x) are:

Step-by-step explanation:

Aops Question

The value if you subtract the numerator from the denominator will be -67.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that expressing the reciprocal of $1.67$ as a simplified fraction. The number when you subtract the numerator from the denominator will be calculated as below:-

Fraction form of the number 1.67 = 167 / 100.

The subtraction of numerator from denominator = 10  - 167 = -67

Therefore, the value of subtraction of the numerator from the denominator will be -67.

Answer:

1100

Step-by-step explanation:

price = 1500

discount= 15%

15% of 1500 = (15/100)*1500= 15*15= 225

so selling price = 1275

profit is selling price - cost price

1275 - CP = 175

CP = 1275-175= 1100

Answer:

y = 4x

Step-by-step explanation:

To start, we need to find the slope:

m = y₁ - y₂ / x₁ - x₂

Substitute the numbers and solve for the slope:

m = -4 - (-8) / -1 - (-2)

m = -4 + 8 / -1 + 2

m = 4 / 1

m = 4

Now we know that the slope is 4.

Next, we need to use point-slope form:

y - y₁ = m(x - x₁)

Once more, substitute the numbers:

y - (-4) = 4(x - (-1))

y + 4 = 4(x + 1)

y + 4 = 4x + 4

y = 4x

Therefore, the equation of the line is y = 4x.

Answer:

The slope of the line is [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

The Slope of a Line

Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

It's given the points (1,3) and (-2,2). Let's calculate the slope:

[tex]\displaystyle m=\frac{2-3}{-2-1}[/tex]

Calculating:

[tex]\displaystyle m=\frac{-1}{-3}[/tex]

[tex]\displaystyle m=\frac{1}{3}[/tex]

The slope of the line is [tex]\frac{1}{3}[/tex]

Answer:

(2, - 3.5)

Step-by-step explanation:

K(3, - 3)

L(2, 1)

[tex]m_{KL}[/tex] = [tex]\frac{-3-1}{3-2}[/tex] = - 4

Slope of perpendicular line is [tex]\frac{1}{4}[/tex]

y - 1 = - 4(x - 2) ⇔ y = - 4x + 9

Equation of the perpendicular to KL from point M(4, - 3) is

y - (- 3) = [tex]\frac{1}{4}[/tex] (x - 4) ⇔ y = [tex]\frac{1}{4}[/tex] x - 4 ....... (1)

L(2, 1)

M(4, - 3)

[tex]m_{LM}[/tex] = [tex]\frac{-3-1}{4-2}[/tex] = - 2

Slope of perpendicular line is [tex]\frac{1}{2}[/tex]  

y - 1 = - 2(x - 2) ⇔ y = - 2x + 5

Equation of the perpendicular to LM from point K(3, - 3) is

y + 3 = [tex]\frac{1}{2}[/tex] (x - 3) ⇔ y = [tex]\frac{1}{2}[/tex] x - 4.5 ....... (2)

The coordinates of the intersect of lines (1) and (2)

[tex]\frac{1}{2}[/tex] x - 4.5 = [tex]\frac{1}{4}[/tex] x - 4 ⇒ [tex]\frac{1}{4}[/tex] x = 0.5 ⇒ x = 2

y = [tex]\frac{1}{2}[/tex] (2) - 4.5 ⇒ y = - 3.5

Option C is correct

Answer:

[tex] \frac{x}{x - 1} + \frac{2}{x + 2} = \frac{ - 6}{ {x}^{2} + x - 2 } \\ \frac{x(x + 2) + 2(x - 1)}{(x - 1)(x + 2)} = \frac{ - 6}{ {x}^{2} + x - 2} \\ \frac{ {x}^{2} + 2x + 2x - 2 }{ {x}^{2} + 2x - x - 2} = \frac{ - 6}{ {x}^{2} + x - 2} \\ \frac{ {x}^{2} + 4x - 2 }{ {x}^{2} + x - 2} = \frac{ - 6}{ {x}^{2} + x - 2 } \\ {x}^{2} + 4x - 2 = - 6 \\ {x}^{2} + 4x + 4 = 0 \\ {x}^{2} + 2 \times 2 \times x + {2}^{2} = 0 \\ {(x + 2)}^{2} = 0 \\ x + 2 = 0 \\ \boxed{x = - 2 }[/tex]

C. the equation has one extraneous solution.

Answer:

x>-9

Step-by-step explanation:

The given inequality is :

-3x - 7 < 20

We need to find the solution of the inequality using graph.

-3x - 7 < 20

Add 7 to both sides

-3x-7+7 < 20+7

-3x <27

x>-9

Hence, the attatched graph shows the solution of the given inequality.

Answer:

[tex]a d = bc[/tex]

[tex]da = cb[/tex]

[tex]bc = ad[/tex]

Step-by-step explanation:

Given

[tex]\frac{a}{b} = \frac{c}{d}[/tex]

Required

Choose equivalent expressions

First, cross multiply

[tex]a * d = b * c[/tex]

[tex]a d = bc[/tex]

The product: [tex]a * d = b * c[/tex] can also be rewritten as:

[tex]da = cb[/tex]

Apply symmetric property of inequality

[tex]a d = bc[/tex] becomes [tex]bc = ad[/tex]

and

[tex]da = cb[/tex] becomes [tex]cb = da[/tex]

Answer:

17

Step-by-step explanation:

First, we notice that the triangle is isosceles . (In case you didn't know, the two tick marks on the sides of the triangle signify that they are congruent and have the same length.) Since the triangle is isosceles, we can apply the Base Angles Theorem.

The Base Angle Theorem states that the two angles opposite of the two congruent sides are also congruent. In this case, we can say that, because the angle measuring 29° and the third(top) angle are opposite to the two congruent sides, those two angles are congruent. Therefore, the third angle measures 29° as well.

Now that we know this, we can write the following equation:

29°+29°+(11x-65)° = 180.

Solving this equation, we have x = 17.

Answer: C

Step-by-step explanation: Since we know both the slope and the y-intercept we can plug them into Slope-Intercept form. Slope-Intercept form is y=mx+b

Since m = 2 and b = -3/4 all we have to do is replace both m and b in the form and that would be the answer. y = 2x-3/4

Answer: (A) 22.5 mins

Step-by-step explanation:

Given data:

Duration of the match = 90mins.

Number of substitutes = 4.

Solution:

Since Each of the four (4) substitute players alternated equally, simply means each of the 4 players spent an equal amount of time on the football pitch.

= 90mins/4

= 22.5mins.

Each player spent 22.5minutes on the football pitch.

The division of total time distribute the same time for each substitutes player.

The duration for which each substitute player plays the game of football is 22.5 minutes.

Division of total time by the units of division provides the equal time for each unit.

Given information-

A game of football with 11 players lasts for exactly 90 minutes.

Total number of substitutes is 4.

All the players plays for the same length of time.

As there is total number of substitute players are 4 and the total time duration is 4.

Thus for each player to play same length of time, the time should be divided by the number of players. Therefore,

[tex]t=\dfrac{90}{4} \\t=22.5[/tex]

Hence the duration for which each substitute player plays the game of football is 22.5 minutes.
