Answers

The correct answer is 4g. Spaghetti is a great source of fiber, with 4g per serving.

What is fiber?

Fiber is a type of carbohydrate found in plant-based foods. It is not digested or absorbed by the body, but instead passes through the digestive system and out of the body. Fiber helps promote healthy digestion by adding bulk to the stool, helping it to pass through the intestines more quickly.

Fiber is an essential part of a healthy diet. It helps to keep your digestive system functioning properly, reduce cholesterol levels, and aid in weight management. It can be found in many plant-based foods, as well as some animal-based products. Spaghetti is a great source of fiber, with 4g per serving. This is a good amount for a meal, and it can help you meet your daily fiber needs. Eating a variety of foods that are high in fiber can help you stay healthy and reach your dietary goals. Getting enough fiber in your diet can also help reduce your risk of diabetes, heart disease, and stroke. So, the correct answer is 4g of fiber per serving of spaghetti.

How much do we need to invest at 12% simple interest in order to have a total of $12,400 in 2 years?

Answers

Answer:

$10,000

Step-by-step explanation:

Let

Principal= x

Rate = 12%

Time = 2 years

Interest = (Final amount with interest placed on it) - Principal

Therefore,

Interest = 12,400 - x

Using

I = (P·r·t) / 100

Making P, subject of formula,

P = (100·I) / (R·T)

x = [100·(12,400 - x)] / (12.2)

x = (1,240,000 - 100x) / 24

Cross multiply,

24x = 1,240,000 -100x

24x + 100x = 1,240,000

124x = 1,240,000

x = 1,240,000 / 124

x = 10,000

The dimensions of the triangle have been doubled in this case so, the perimeter will also be doubled, and the area will be four times.

How do you calculate a triangle's area and perimeter?

The entire area filled by a triangle's three sides on a two-dimensional plane is known as the triangle's area. A = 1/2 b h is the basic equation for a triangle's area, where b and h represent the base and height of the triangle, respectively.

The triangle's perimeter is equal to the product of its three sides.

This formula can be used to determine any triangle shape, including scalene, isosceles, and equilateral triangles. Remember that the base and height of a triangle are perpendicular to one another.

In the given question the original dimensions of the equal sides = 2.5 units.

[tex]P(x) = x^4 - x^3 - 11x^2 + 9x + 18[/tex]. Describe to the CEO what the graph looks like and, in general, how to sketch the graph without using technology. Use complete sentences, and focus on the end behaviours of the graph and where the company will break even (where P(x) = 0)

Answers

The graph of the function P(x) = x^4 - x^3 - 11x^2 + 9x + 18 rises on both ends and intersects the x-axis at x = -2, x = -1, and x = 3. The graph intersects the y-axis at the point (0, 18). The company will break even at the points where P(x) = 0, which are x = -2, x = -1, and x = 3.

How did we arrive at this assertion?

The function P(x) = x^4 - x^3 - 11x^2 + 9x + 18 is a polynomial function of degree 4.

To sketch the graph of this function without using technology, we can start by analyzing the end behaviors of the function. As x approaches negative infinity, the leading term of the function, x^4, dominates and the function approaches positive infinity. As x approaches positive infinity, the leading term also dominates and the function again approaches positive infinity. This means that the graph will have a shape that rises on both ends.

Next, we can find the x-intercepts of the function, which are the values of x where P(x) = 0. We can use synthetic division or factorization to find that the function has three real roots: x = -2, x = -1, and x = 3. These values represent the points where the graph intersects the x-axis.

Finally, we can find the y-intercept of the function, which is the value of P(0). We can plug in x = 0 into the function to find that P(0) = 18. This means that the graph intersects the y-axis at the point (0, 18).

Putting all of this information together, we can sketch a rough graph of the function. The graph rises on both ends and intersects the x-axis at x = -2, x = -1, and x = 3. The graph intersects the y-axis at the point (0, 18). The function is positive between x = -2 and x = -1, and between x = 3 and positive infinity. The function is negative between x = -1 and x = 3.

To summarize, the graph of the function P(x) = x^4 - x^3 - 11x^2 + 9x + 18 rises on both ends and intersects the x-axis at x = -2, x = -1, and x = 3. The graph intersects the y-axis at the point (0, 18). The company will break even at the points where P(x) = 0, which are x = -2, x = -1, and x = 3.

Need to find the angle for each letter . Will be great if I can get the answer tonight

Answers

The measure of the angle for each letter found by finding the variables representing the angles simultaneously using circle theorems are;

a = 90°, b = 12°, c = 64°, d = 52°, e = 52°, f = 48°, g = 66°, h = 32°, i = 36°, j = 20°

What is a simultaneous equation?

A simultaneous equation consists of two or more equations that consists of the same variables.

The evaluation of the angles in the circle are presented as follows;

a + a = 180° (linear pair angles)

2·a = 180°

a = 180°/2 = 90°

a = 90°

The 32° angle indicates that the base angle of the large isosceles triangle is 2 × 32° = 64°

Angle c is a base angle of the isosceles triangle, therefore, we get;

c = 64°

Angle b + 90° + 78° = 180° (Angle sum property of a triangle)

b = 180° - (90° + 78°) = 12°

b = 12°

In the isosceles triangle with angle 2·b, and the isosceles triangle formed by the radii to the vertices, we get;

2·b + 2·b = f, therefore;

f = 2·b + 2·b = 4·b

f = 4·b

f = 4 × 12° = 48°

f = 48°

The measure of angle g is equivalent to the measure of a base angle of the isosceles triangle with the angle 2·b, with angle f = 48° being a vertex of the triangle, therefore;

g = (180° - 48°)/2 = 66°

g = 66°

Vertex angle of the cyclic quadrilateral with 5·b can be found as follows;

2·f + The vertex angle = 180°

Vertex angle = 180° - 2 × 48° = 84°

Vertex angle = 84°

5·b + 2·h + i + j = 180°

5 × 12 + 2·h + i + j = 180°

60° + 2·h + i + j = 180°

2·h + i + j = 180° - 60° = 120°

2·h + i + j = 120°...(1)

2 × 2·h + 2 × j = 2 × 84°

2·h + j = 84°...(2)

2·f + 5·b + i + 168° = 360°

i = 360° - 2·f + 5·b + 168°

i = 360 - (96 + 60 + 168) = 36

2·h + i + j - (2·h + j) = 120° - 84° = 36°

i = 36°

5·b + 2·h + 2·f + i + j + 84° = 360°

60° + 2·h + 96° + 36° + j + 84° = 360°

2·h + j = 360° - 84° - 36° - 60° - 96°  = 84°

2·h + j = 84°

The two tangent theorem indicates that we get;

90° - 64° = 26°

180° - 2 × 26° = 128°

h = (180° - 128°/2)/2 - 26° = 32°

h = 32°

2·h + j = 84°

j = 84° - 2·h

j = 84° - 2 × 32° = 20°

j = 20°

d = e (Angles subtended by the same chord)

2·c + d = 180°

2 × 64° + d = 180°

d = 180° - 2 × 64° = 52°

$230. After four months, he has $329 saved.

Answers

According to the given information, Jeremy is saving approximately $20.56 per week for his new tires.

What is basic arithmetic?

Basic arithmetic refers to the fundamental operations of arithmetic, which include addition, subtraction, multiplication, and division. These operations are used to perform calculations with numbers, such as counting, computing sums, finding differences, calculating products, and determining quotients.

We can use this information to find Jeremy's weekly savings rate.

To find the weekly savings rate, we need to first find out how much Jeremy saves in a week.

For the next three months, which is 12 weeks, he saves an additional $329 - $230 = $99.

Therefore, in total, Jeremy saves $230 + $99 = $329 in 16 weeks.

His weekly savings rate is then:

$329 / 16 weeks = $20.56 per week (rounded to the nearest cent)

So, Jeremy is saving approximately $20.56 per week for his new tires.

A line passes through the point (2, - 3) and has a slope of - 4.
Write an equation in slope-intercept form for this line.

Answers

Answer:

y = -4x + 5.

Step-by-step explanation:

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Given that the line passes through the point (2, -3) and has a slope of -4, we can use the point-slope form of a linear equation to find the y-intercept:

y - y1 = m(x - x1)

where x1 and y1 are the coordinates of the given point, and m is the slope.

Substituting the given values, we get:

y - (-3) = -4(x - 2)

Simplifying and rearranging, we get:

y + 3 = -4x + 8

Subtracting 3 from both sides, we get:

y = -4x + 5

Therefore, the equation in slope-intercept form for the given line is y = -4x + 5.

Answers

The values of the limits of g(x) as x approaches 33 minus and 33 plus can be determined by examining the table of values and looking for the values of g(x) as x gets closer and closer to 33 from the left and the right sides.

As x approaches 33 from the left (i.e., values of x slightly less than 33), we can see from the table that the values of g(x) decrease from -7 to -16. Therefore, the limit of g(x) as x approaches 33 from the left is -16.

As x approaches 33 from the right (i.e., values of x slightly greater than 33), we can see from the table that the values of g(x) increase from -6.1 to -7. Therefore, the limit of g(x) as x approaches 33 from the right is -7.

Therefore, the correct answer is:

Limit of g(x) = negative 16 as x approaches 33 minus and limit of g(x) = negative 7 as x approaches 33 plus.

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the total cost of the deal be represented as A

Let the initial price of the router be = $ 39.99

Now , the percentage of discount for the router = 15 %

So , the final cost of the router = ( 85/100 ) x 39.99

On simplifying , we get

The final cost of the router = $ 33.9915

Now , the number of months = 18 months

The contract rate = $ 56.99 per month

So , the total contract rate for 18 months = 18 x 56.99

The total contract rate for 18 months = $ 1,025.82

Now , total cost of the deal A = final cost of the router + total contract rate for 18 months

On simplifying the equation , we get

The total cost of the deal A = $ 1,025.82 + $ 33.9915

The total cost of the deal A = $ 1059.8115

The total cost of the deal A = $ 1059.81

Hence , the total cost of the deal is $ 1059.81

a. Use the appropriate formula to find the value of the annuity.
b. Find the interest.
Periodic Deposit
$2000 at the end of each year
Rate
3.5% compounded annually
Time
10 years

Answers

The annuity is $2800 and interest is $800.

What is the compound interest?

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex].

Given that, P= $2000 at the end of each year, R= 3.5% compounded annually and time = 10 years

Amount = 2000(1+3.5/100)¹⁰

= 2000(1+0.035)¹⁰

= 2000(1.035)¹⁰

= 2000×1.4

= $2800

Interest = 2800-2000

= $800

Therefore, the annuity is $2800 and interest is $800.

What are congruent triangles and their property?

Two  harmonious triangles have identical areas and  peripheries. Each of a triangle's sides and angles is an exact match to its  harmonious triangle's corresponding sides and angles. We can  use five different  parcels to show that any two triangles are  harmonious SSS, SAS, AAS, ASA, and RHS.  

The SAS criterion stands for the Side- Angle- Side criterion. This standard  countries that two triangles are  harmonious if they've matching sides and included angles on  contrary sides of each other.

Side- Side- Side criterion is appertained to as the SSS criterion. According to this standard, two triangles are  harmonious if their  separate triangles' three sides are equal to one another.

triangles. Find BC.

Answers

The length of BC  in the triangle is 24 units.

How to find the similar triangle?

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

Therefore, using proportion,

BC / x = 12 / x - 4 = x + 7 / 5

12 / x - 4 = x + 7 / 5

cross multiply

12 × 5 = (x - 4)(x + 7)

60 = x² + 7x - 4x - 28

x² + 3x - 28 - 60 = 0

x² + 3x - 88 = 0

x² - 8x + 11x - 88 = 0

x(x - 8) + 11(x - 8) = 0

(x + 11)(x - 8) = 0

Therefore,

x = - 11 and x = 8

Hence,

BC / x = 12 / x - 4

BC / 8 = 12 / 8 - 4

BC / 8 = 12 / 4

4BC = 96

BC = 96 / 4

BC = 24 units
