Answer:

g(3a – 6) = a - 4

Step-by-step explanation:

g(x) = 1/3x - 2

g(3a – 6) = 1/3(3a – 6) - 2

= a - 2 - 2

= a - 4

Answer:

g(3a - 6) = a - 4

Step-by-step explanation:

If you start with g(x) = 1/3 x - 2

Then whatever x = on the left, must take on the value on the right.

g(3a - 6) = 1/3 (3a - 6) - 2     Notice the x is gone and 3a - 6 has taken it's place.

Now you must distribute the 1/3 for both 2a and 6

g(3a - 6) = 1/3 * 3a - 1/3 * 6 - 2

g(3a - 6) = a - 2 - 2

g(3a - 6) = a - 4

Answer: B

Fourth diagram represent the 14x²+21x in factored form is 7x(2x + 3)

A number system is defined as a system of writing to express numbers.

The given expression is 14x²+21x

Fourteen x square plus twenty one times of x.

x is the variable and plus is the operator.

14x²+21x

We need to take 7x as common from two terms.

When the quadratic expression is a product of two factors where each one is a linear expression, this is called the factored form.

Seven x is product of two times of x plus three.

7x(2x+3)

The fourth diagram represent the 14x²+21x in factored form is 7x(2x + 3)

Step-by-step explanation:

To find the improper fraction change the whole number into a fraction:

3 *5/5 = 15/5 which is the same as 3

then add the remaining 3/5 to the fraction

15/5 + 3/5

Answer:

Claire has 16 stamps

Step-by-step explanation:

Proportions

If two variables are proportional, their ratio is constant. For example, the distance traveled by car is proportional to the time it travels at a constant speed. We write it as d:t=constant.

It's known the number of Claire's stamps to the number of John's stamps is 2:3 and John has 24 stamps.

This means the following relation must stand:

[tex]\displaystyle \frac{C}{J}=\frac{2}{3}[/tex]

Where C is the number of stamps of Claire and J is the number of stamps of John. We know J=24, thus:

[tex]\displaystyle \frac{C}{24}=\frac{2}{3}[/tex]

Solving for C:

[tex]\displaystyle C=24\cdot\frac{2}{3}[/tex]

C = 16

Let the amount of water at beginning be x

x-1.5-0.750-2.250=1

x=5.5 litre

Step-by-step explanation:

Therefore there was 5 litre 5 mililters of water in the pail.

Answer:5500 ml or 5.5 liters

Step-by-step explanation:

First, we should note that there are 1000 milliliters in 1 liter of liquid.

So, in milliliters, Peter filled three containers with 1500 ml, 750ml, and 2250 ml with 1000ml left over.

To find the total amount, we find the sum of all the milliliters:

1500 + 750 + 2250 + 1000 = 5500 ml

Again, we know that there are 1000 milliliters in 1 liter of liquid, so:

= 5.5 liters

Answer:

1250 m²

Step-by-step explanation:

Let x and y denote the sides of the rectangular research plot.

Thus, area is;

A = xy

Now, we are told that end of the plot already has an erected wall. This means we are left with 3 sides to work with.

Thus, if y is the erected wall, and we are using 100m wire for the remaining sides, it means;

2x + y = 100

Thus, y = 100 - 2x

Since A = xy

We have; A = x(100 - 2x)

A = 100x - 2x²

At maximum area, dA/dx = 0.thus;

dA/dx = 100 - 4x

-4x + 100 = 0

4x = 100

x = 100/4

x = 25

Let's confirm if it is maximum from d²A/dx²

d²A/dx² = -4. This is less than 0 and thus it's maximum.

Let's plug in 25 for x in the area equation;

A_max = 25(100 - 2(25))

A_max = 1250 m²

-2x + 6 + 6x = 6 (2x - 3) this is the equation

-2x + 6 + 6x = 12x - 18 distributive property has been applied

4x + 6 = 12x - 18 like terms have been added

6 = 8x -18 4x has been subtracted from both sides

24 = 8x -18 has been added to both sides

3 = x 8 has been divided from both sides

Answer:

[tex]\frac{dr}{dh} =-\frac{r}{2h}[/tex]

Step-by-step explanation:

The volume of a cylinder is given by the formula:

V = πr²h,

Where V is the volume, r is the radius of the cylinder and h is the height of the cylinder.

We are to express the rate of change of the radius of the clay with respect to the height of the clay in terms of height h and radius r.

That means we express dr / dh in terms of height h and radius r. To do this, we have to first differentiate the volume with respect to the height, i.e. find dV / dh:

V = πr²h

[tex]\frac{dV}{dh}= \frac{d}{dh} (\pi r^2h)\\\\\frac{dV}{dh}= \pi r^2 + 2\pi rh \frac{dr}{dh} \\\\The\ volume\ is\ constant\ hence\ \frac{dV}{dh}=0.\ We\ get\ that:\\\\0= \pi r^2 + 2\pi rh \frac{dr}{dh}\\\\- \pi r^2 =2\pi rh \frac{dr}{dh}\\\\ \frac{dr}{dh}=-\frac{\pi r^2}{2\pi rh}\\\\ \frac{dr}{dh}=-\frac{r}{2h}[/tex]:

Answer:

a. 76 cm

b. 16 in.

c. 225 cm

Step-by-step explanation:

a. Converting 30 inches to centimetres:

When y(inches) = 30, x (centimetres) = 76

So, 30 in. = 76 cm

b. When x (cm) = 40, y (in.) = 16

So, 40 cm = 16 in.

c. Given that a fence is 7 ft 6 in. high, and 1 ft = 12 in., to find the height of the fence in cm, first convert the height to in.

Convert 7ft to inches:

If 1 ft = 12 in., then,

7 ft = 7*12 = 84 inches

The height of the fence in inches = 84 + 6 = 90 inches

Using the graph, find the unit rate using any point on the line, say (100, 40):

Unit rate = y/x = inches/centimeters =

Unit rate (m) = 40/100 = ⅖

Write an equation for the line:

To do this, substitute m = ⅖ into y = mx

Equation: y = ⅖x

Let's convert the height of the fence, 90 inches, to centimetres:

To convert to cm, substitute y = 90 into y = ⅖x

Thus:

90 = ⅖*x

5*90 = 2x

450 = 2x

Divide both sides by 2

450/2 = x

225 = x

Height of the fence in cm = 225 cm

Answer:

Radius, r = 26.57 cm and diameter = 53.14 cm

Step-by-step explanation:

Given that,

The circumference of a coin, C = 167 cm

We need to find the radius and the diameter of the coin.

The formula for the circumference of a circle is given by :

[tex]C=2\pi r[/tex]

Where

r is radius of coin

[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{167}{2\pi}\\\\r=26.57\ cm[/tex]

Diameter, d = 2r

d = 2(26.57) cm

= 53.14 cm

Hence, this is the required solution.

Answer:

x = 5.943

Step-by-step explanation:

Reference angle = 23°

Side opposite to reference angle = x

Adjacent side = 14

Therefore, we would apply TOA to find x.

Thus:

tan (23) = x/14

Multiply both sides by 14

14 × tan(23) = x

5.94264742 = x

x = 5.943 (to 3 decimal places)

Answer:

3i

Step-by-step explanation:

3i x 3i = -9

-3i x -3i = -9

Therefore the square root of -9 is 3i or -3i

The simplified radical expression ±√(-9) is ±3i

The expression ±√(-9) involves finding the square root of a negative number. In the real number system, this is not possible, as no real number multiplied by itself will result in a negative value. To overcome this limitation, mathematicians introduced the concept of imaginary numbers. The imaginary unit, denoted by 'i,' is defined as √(-1).

Now, let's simplify the expression ±√(-9) step by step:

Step 1: Begin by recognizing that √(-9) is the square root of -9.

Step 2: Since √(-1) is 'i,' we can rewrite √(-9) as √(9) * √(-1).

Step 3: The square root of 9 (√9) is 3.

Step 4: Replace √(-1) with 'i.'

Step 5: The final result is 3i.

Therefore, the simplified form of ±√(-9) is ±3i.
