Answer 1

The diagonals of a rectangle are congruent, so RT = SU, that is

3x + 8 = 6x - 4 (subtract 4x from both sides)

3x + 8 = 6x - 4

Subtract 8 from both sides 3x + 8 - 8 = 6x - 4 - 8

Simplifying the above equation, we get

3x = 6x-12

Subtract 6x from both sides 3x - 6x = 6x - 12 - 6x

Simplifying the above equation, we get

-3x = -12

Divide both sides by -3

[tex]$\frac{-3 x}{-3}=\frac{-12}{-3}[/tex]

x = 4

Then, R T= 3x + 8 = 3(4) + 8 = 20

The diagonals bisect each other, then

RV = 0.5 × 20 = 10

∠ RVU = ∠ SVT = 54° ( vertical angles)

RV = UV ( diagonals are congruent and bisect each other)

Then Δ RVU is isosceles with base angles congruent, then

∠ VUR =[tex]$\frac{180-48}{2}[/tex] = 66°.

Answer 2

In the rectangle, RV = 3x+8, SV = 6x-4, and ∠ VRS = 54° then the value of x is 4 and ∠ VUR is 66°.

How to estimate the value of x?

The diagonals of a rectangle are congruent, so RT = SU, that is

3x + 8 = 6x - 4 (subtract 4x from both sides)

3x + 8 = 6x - 4

Subtract 8 from both sides 3x + 8 - 8 = 6x - 4 - 8

Simplifying the above equation, we get

3x = 6x-12

Subtract 6x from both sides 3x - 6x = 6x - 12 - 6x

Simplifying the above equation, we get

-3x = -12

Divide both sides by -3

[tex]$\frac{-3 x}{-3}=\frac{-12}{-3}[/tex]

x = 4

Then, R T= 3x + 8 = 3(4) + 8 = 20

The diagonals bisect each other, then

RV = 0.5 × 20 = 10

∠ RVU = ∠ SVT = 54° ( vertical angles)

RV = UV ( diagonals are congruent and bisect each other)

Then Δ RVU is isosceles with base angles congruent, then

A Ford F-150 truck is considered a half-ton truck because that is how much it can haul. How many pounds can the truck haul?

Answers

The truck can haul 1102 pounds.

According to the question,

We have the following information:

A Ford F-150 truck is considered a half-ton truck because that is how much it can haul.

(We will not directly convert ton into pounds. We will follow the following steps.)

Now, we know that 1 ton is equal to 1000 kilograms.

So, half ton makes 500 kg.

Now, to convert this into pounds, we will multiply 500 kg by 2.205 because we know that 1 kg is equal to 2.205 pounds.

1 kg = 2.205 pounds

500 kg = (500*2.205) pounds

500 kg = 1102.5 pounds

Hence, the truck can haul 1102.5 pounds.

D. It has a range of 22.

Answers

The correct option is option D) it has range of 22

What is the range of a dataset?

It the difference between the minimum and maximum value of the dataset.

We are given a dataset with a histogram and we are asked to find out which of the given options does not describe the data

We find the answer by eliminating the correct option

Our given dataset contains 10 points

Hence the median will be the average of 5th and 6th element

Here the 5th and 6th elements are 17

Hence the median of the dataset is 17

Similarly 17 is repeated 4 times in the dataset. i.e highest number of times

Hence 17 is the mode of the dataset

If you look clearly at the histogram from median it is symmetrical that is left side equal to the right side

But if you look at the range the minimum value is 13 and maximum value is 21

Hence the range of the function is 21-13=8

And not 22

Hence the correct option is option D)

Answer:

m = -5

n = -2

Step-by-step explanation:

5m + 6n = -37

10m + 4n = -58 multiply first equation by -2

-2 × 5m + 6n = -37

-10m + (-12n) = 74 now add two equations up

10m - 10m + 4n - 12n = 74 - 58 add/ subtract like terms

-8n = 16 divide both sides by -8

n = -2

to find the value of m, replace n with -2 in the first equation

5m + 6*(-2) = -37

5m - 12 = -37 add 12 to both sides

5m = -25 divide both sides by 5

[tex]2^{100}[/tex]  = 1,267,650,600,228,229,401,496,703,205,376

Then dividing 2 to the 100th power by 5:

1,267,650,600,228,229,401,496,703,205,376 / 5 = 253,530,120,045,645,880,299,340,641,075  (without considering the decimal value)

This tells us how many times 5 can divide 2 to the 100th power.

Find g(a) + h(a)

Answers

The value of g(a) + h(a) is a²-3a-2 or (a-2)(a-1) using addition of functions.

What is the Function?

Given a collection of inputs X (domain) and a set of potential outputs Y (codomain), a function is more technically defined as a set of ordered pairings (x,y) where x belongs to X  and y belongs to Y, with the caveat that there can only be one ordered pair with the same value of x. The function notation f:XY can be used to express that f is a function from X to Y

Adding two functions-

g(a) = a²- 2

h(a) = -3a

Let h(a) be g(a) + h(a)

So h(a) = a² - 2 - 3a.

We can factorize the function into (a-2)(a-1).

So we get h(a) = (a-2)(a-1).

How to find the perimeter of a triangle?

A triangle is a a polygon with three sides. The sum of angles in a triangle is 180 degrees.

The perimeter of a triangle is the sum of the whole three sides.

Therefore, the simplified expression that represents the perimeter of the triangle is as follows:

Hence, the three sides of the triangle are as follows;

1.5x - 31.5x - 30.75x - 1

Hence,

perimeter of the triangle = 1.5x - 3 + 1.5x - 3 + 0.75x - 1

perimeter of the triangle = 1.5x + 1.5x + 0.75x - 3 - 3 - 1

perimeter of the triangle = 3.0x + 0.75x - 7

perimeter of the triangle = 3.75x - 7

Answers

The largest prime factor that always divides the sum of the terms in the sequence is 37.

The sequence is finite and consists of three-digit integers.

The tens and units digits of each term are, respectively, the hundreds and tens digits of the next term, and the tens and units digits of the last term are, respectively, the hundreds and tens digits of the first term.

From the above property of the sequence, we can see that each digit at the units, tens as well as hundreds place will appear the same number of times in the sequence.

Let "x" be the sum of the digits at unit place in all the terms.

The sum of all the terms is "S".

S = 111*x

S = 3*37*x

We can clearly see that the sum "S" is divisible by 37.

Hence, the largest prime factor that always divides the sum of the terms in the sequence is 37.

B.The range will be all real numbers.
C.The range will change from y ≥ 0 to y ≥ -3.
D.The range will change from x ≥ 0 to x ≥ -3.

Answers

1) A translation of 3 units down, option D.

2) The vertex moves 3 units down.

3) The new range is y ≥ -3, correct option is C.

Which transformation is applied?

For a function f(x) a vertical shift of N units is written as:

g(x) = f(x) + N

In this case, we have:

f(x) = |x|

h(x) = |x| - 3

Then h(x) = f(x) - 3

This is a shift of 3 units down, the correct option is D.

How is the vertex affected?

The vertex is translated 3 units down, like the whole graph of the function.

How is the range affected?

The vertex defines the minimum of the range, so if the vertex goes 3 units down, then the range also does, the new range will be:

y ≥ -3.

So the correct option is C.

A force is a vector quantity since it has both magnitude and direction. It is calculated using the newton SI unit (N). Force is denoted by the letter F.Thrust, which increases an object's velocity; drag, which decreases an object's velocity; and torque, which causes changes in an object's rotational speed, are all concepts connected to force. Each part of an extended body often exerts stresses on the sections that are nearby; the distribution of these forces throughout the body is what is known as the internal mechanical stress. Due to the balance of the forces, such internal mechanical stresses do not generate acceleration of that body. Pressure is a straightforward form of stress that, if unbalanced, can cause the body to accelerate. Pressure is the distribution of several small forces applied over an area of a body. Stress typically results in the flow of fluids or the deformation of solid materials.

1. The mathematical expression for the length is C. 2x + 5.

2. The quadratic equation is A. 2x² + 5x - 18 = 0.

3. The width of the tarpaulin is A. 2 ft.

4. The length of the tarpaulin is D. 9 ft.

5. The perimeter of the tarpaulin is C. 22 feet.

How to calculate the value?

From the information, the following can be deduced:

Width = x

Length = (2 × x) + 5 = 2x + 5

Area = 18 ft²

The equation will be:

Length × Width =Area

(2x + 5)x = 18

2x² + 5x = 18

2x² + 5x - 18 = 0

2x² - 4x + 9x - 18 = 0

2x(x - 2) + 9(x - 2)

Therefore, x - 2 = 0

x = 0 + 2 = 2

Width = 2

Length = 2x + 5 = 2(2) + 5 = 9ft

Perimeter = 2( Length + Width)

= 2(2 + 9)

= 22 feet.

This illustrates the concept of addition to calculate the perimeter.
