factorise P(x)=2x*3-5.6x+1

The image polygon P'S'R'T' has vertices P'(-5, 1), S'(0, -1), R'(3, -2), and T'(-2, -4).

To determine the image vertices of P' when the preimage is rotated 90° counterclockwise, we can use the following formula:

(x', y') = (-y, x)

where (x, y) are the coordinates of the preimage vertex, and (x', y') are the coordinates of the image vertex after rotation.

Using this formula for each vertex of the polygon PSRT, we get:

For P(1, 5), rotating 90° counterclockwise gives us P'(-5, 1).

For S(1, 0), rotating 90° counterclockwise gives us S'(0, -1).

For R(-2, -3), rotating 90° counterclockwise gives us R'(3, -2).

For T(-4, 2), rotating 90° counterclockwise gives us T'(-2, -4).

Therefore, the image polygon P'S'R'T' has vertices P'(-5, 1), S'(0, -1), R'(3, -2), and T'(-2, -4).

Answer:

720 m^2

Step-by-step explanation:

Solution:

The formula for the surface area of a triangular prism is:

Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area)

= (S1 +S2 + S3)L + bh

where,

Given:

side 1 (S1) : 5 m

side 2(S2): x m

side 3(S3): 12 m

length (l)=22m

Here we need to find side 2, we can easily find it using Pythagoras' theorem.

a^2+b^2=c^2

5^2+12^2=x^2

x^2=169

x=[tex]\sqrt{169}=13 m[/tex]

therefore, side 2 is 13 m.

Substituting value in the formula

Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area)

= (S1 +S2 + S3)L + bh

Surface Area=(5+13+12)*22+5*12= 720 m^2

Answer:

720 m²

Step-by-step explanation:

The given diagram shows a triangular prism.

A triangular prism consists of two congruent triangular bases and three rectangular faces connecting these bases.

To calculate the surface area of the triangular prism, we first need to calculate the length of the hypotenuse of the right triangular base. To do this, we can use Pythagoras Theorem:

[tex]\begin{aligned}\sf Hypotenuse\;of\;triangular\;base&=\sqrt{5^2+12^2}\\&=\sqrt{25+144}\\&=\sqrt{169}\\&=13\; \sf m\end{aligned}[/tex]

The surface area of a triangular prism is the sum of the areas of all its faces. Therefore:

[tex]\begin{aligned}\sf Total\;surface\;area&=2\left(\dfrac{1}{2} \cdot 5 \cdot 12\right)+12\cdot 22+5 \cdot 22+13 \cdot 22\\\\&=60+264+110+286\\\\&=720\; \sf m^2\end{aligned}[/tex]

Therefore, the total surface area of the given triangular prism is 720 m².

The value of the y-intercept of the graph of the function h(x) = 12.3(4.9)^x is 12.3.

To determine the value of the y-intercept of the graph of the function[tex]h(x) = 12.3(4.9)^x,[/tex] we need to find the value of h(0) since the y-intercept corresponds to the point where the graph intersects the y-axis (x = 0).

Substituting x = 0 into the function, we have:

[tex]h(0) = 12.3(4.9)^0[/tex]

Since any number raised to the power of 0 is equal to 1, we have:

h(0) = 12.3(1)

Multiplying 12.3 by 1 gives us:

h(0) = 12.3

Therefore, the value of the y-intercept of the graph of [tex]h(x) = 12.3(4.9)^x[/tex] is 12.

The y-intercept represents the value of the function when x = 0, which in this case is 12.3.

It is the point where the graph crosses the y-axis.

This means that when there is no exponential growth or decay (x = 0), the value of the function is 12.3. As x increases or decreases, the function will grow or decay exponentially, but at x = 0, it starts with a value of 12.3.

The graph of this function would start at the point (0, 12.3) and then either increase or decrease exponentially depending on the value of the base (4.9 in this case).

Step-by-step explanation:

The large box weighs 18.75 kg, and the small box weighs 15.75 kg.

We have,

Let's assume the weight of a large box is L kg, and the weight of a small box is S kg.

According to the given information, we can create the following equations:

Equation 1: 3L + 5S = 135 (1st delivery)

Equation 2: 9L + 7S = 279 (2nd delivery)

To solve these equations, we can use a method called "elimination" or "substitution."

Multiply Equation 1 by 3 and Equation 2 by 1, so that the coefficients of L will be the same:

Equation 1: 9L + 15S = 405

Equation 2: 9L + 7S = 279

Now, we can subtract Equation 2 from Equation 1 to eliminate L:

(9L + 15S) - (9L + 7S) = 405 - 279

Simplifying:

8S = 126

Divide both sides of the equation by 8:

S = 126/8 = 15.75

So, the weight of a small box (S) is 15.75 kg.

Now,

substitute the value of S into Equation 1 to find the weight of a large box (L):

3L + 5(15.75) = 135

3L + 78.75 = 135

3L = 135 - 78.75

3L = 56.25

Divide both sides of the equation by 3:

L = 56.25/3 = 18.75

So,

The weight of a large box (L) is 18.75 kg.

Thus,

The large box weighs 18.75 kg, and the small box weighs 15.75 kg.

Once we have those values, we can plug them into the formula and calculate the area of trapezium PQRS. And that's it!

To start, let's quickly review what a trapezium is. A trapezium, also known as a trapezoid, is a four-sided geometric shape with two parallel sides (called the bases) and two non-parallel sides (called the legs). The distance between the two parallel sides is known as the height.
In order to find the area of a trapezium, we use the formula:
Area = (sum of bases x height) / 2
So for trapezium PQRS, we need to identify the length of its two bases and its height in order to use this formula.
Without any specific measurements given in your question, I'll assume we don't have any numerical values to work with. Instead, let's use variables to represent the length of each base and the height.
We can call the shorter base PQ, and the longer base SR. Let's say PQ has a length of 'a' units, and SR has a length of 'b' units. For the height, let's call it h.
So, the formula for the area of trapezium PQRS becomes:
Area = ((a + b) x h) / 2
This means that to find the area of the trapezium, we simply need to know the lengths of the two bases (a and b) and the height (h).
Once we have those values, we can plug them into the formula and calculate the area of trapezium PQRS. And that's it!

Answer:

Step-by-step explanation:

Since the given figure is a right triangle, we can use Pythagorean Theorem

where c² = a² + b²

c = 15

15² = a² + b²

Since 15 is the hypotenuse, we can then say that the possible legs of the triangle are less than 15.

225 - a² = b²

we will do trial and error

let a be 14

225 - 14² = b²

b = √29

a = 14cm, b = √29cm, c = 15cm

let a be 13

225 - 13² = b²

b = 2√14

a = 13cm, b = 2√14cm, c = 15cm

let a be 12

225 - 12² = b²

b = 9

a = 12cm, b = 9cm, c = 15cm

You can solve for other possible values using the same process as above. Since there are no conditions whether the lengths of the legs should be a whole number or not then the above dimensions can be considered. If you're looking for an answer that consists of whole numbers then the answer would be a = 12cm, b = 9cm and c = 15cm

Rounding 473,615 to the nearest hundred gives us 473,600.

In the case of 473,615, the digit in the tens place is 1, which is less than 5. So we keep the digit in the hundreds place (3) the same and round the remaining digits to zero.

The total cost of the items is x + (2/3)x + (1/6)x = (11/6)x.

If we replace specific values for F or C, we will locate the corresponding price for the opposite variable. Here are some examples:

Let's expect C = 20. Substituting this fee into the second equation:

F = (9/five) * 20 + 32

F = 36 + 32

F = 68

C = (five/9) * (100 - 32)

C = (5/9) * 68

C = 340/9

Daisy would be paid $155 if she works 13 hours in a day.

If Daisy works for up to 8 hours in a day, she is paid a flat rate of $10 per hour, so her earnings for the day would be:

Earnings = 10 × 8 = $8

If Daisy works for more than 8 hours in a day, then her earnings for the extra hours are calculated at a rate of 1.5 times her hourly wage, which is $15 per hour.

So, if Daisy works x hours in a day, where x is greater than 8, then her net earnings for the day can be expressed as:

Earnings = 80 + (x - 8) × 15

This expression takes into account the first 8 hours of work, which are paid at a flat rate of $10 per hour, and the extra hours, which are paid at a rate of $15 per hour

If Daisy works 13 hours in a day, then her net earnings for the day would be:
