What is the net displacement from the starting point?​

Answer: x=-16/11

6+11x+10=0

We add all the numbers together, and all the variables

11x+16=0

We move all terms containing x to the left, all other terms to the right

11x=-16

x=-16/11

Answer:

Vertex:

Roots: [tex]x=\frac{5}{3}[/tex] or [tex]x=2[/tex]

Step-by-step explanation:

The given quadratic equation is:

Let [tex]f(x)=3x^2-11x+10[/tex]

We obtain the vertex form by completing the square;

[tex]f(x)=3(x^2-\frac{11}{3}x)+10[/tex]

Add and subtract the square of half the coefficient of x.

[tex]f(x)=3(x^2-\frac{11}{3}x+(-\frac{11}{6})^2+10-3(-\frac{11}{6})^2)[/tex]

This simplifies to

[tex]f(x)=3(x-\frac{11}{6})^2-\frac{1}{12}[/tex]

Hence the vertex is [tex](\frac{11}{6},-\frac{1}{12})[/tex]

We now solve to obtain:

[tex]3(x-\frac{11}{6})^2-\frac{1}{12}=0[/tex]

[tex]3(x-\frac{11}{6})^2=\frac{1}{12})[/tex]

[tex](x-\frac{11}{6})^2=\frac{1}{36})[/tex]

[tex](x-\frac{11}{6})=\pm \sqrt{\frac{1}{36}}[/tex]

[tex]x=\frac{11}{6}\pm \frac{1}{6}[/tex]

[tex]x=\frac{5}{3}[/tex] or [tex]x=2[/tex]

Answer:

90-73=17

the correct answer is 17

For this case we must find the angle "x" of the figure shown.

If we look at the figure, we have to:

AC equals 90 degrees.

So we have to:

[tex]73 + x = 90[/tex]

We clear the value of "x":

[tex]x = 90-73\\x = 17[/tex]

Thus, the value of "x" is 17 degrees.

Answer:

17 degrees

Option A

Answer:

Step-by-step explanation:

[tex]f(x)=3\sqrt{x+3}-6\\\\\text{Domain:}\ x+3\geq0\to x\geq-3\\\\\text{The zero}\to f(x)=0\\\\3\sqrt{x+3}-6=0\qquad\text{add 6 to both sides}\\\\3\sqrt{x+3}=6\qquad\text{divide both sides by 3}\\\\\sqrt{x+3}=2\iff x+3=2^2\\\\x+3=4\qquad\text{subtract 3 from both sides}\\\\x=1[/tex]

Answer:

x=1

Step-by-step explanation:

Given function,

[tex]f(x)=3\sqrt{x+3}-6[/tex]

Since, the zeroes of a function are those input values for which the function gives the output zero,

So, for the zeroes of f(x),

f(x) = 0

[tex]\implies 3\sqrt{x+3}-6=0[/tex]

[tex]3\sqrt{x+3}=6[/tex]      ( Adding 6 on both sides )

[tex]\sqrt{x+3}=2[/tex]        ( Dividing both sides by 3 )

[tex]x+3=4[/tex]                ( Taking square of both sides )

[tex]x = 1[/tex]                   ( Subtracting 3 from both sides )

Hence, the zero of the given function is, x = 1.

First option is correct.

If there is a single variable with no number in front you can assume that there is a 1. How I think of it is that all singular variables have an invisible one in front

so...

4x - 1x

Since these are like terms you may subtract them like normal numbers. The only difference is that you'll have to add an x at the end of your answer

considering the diagram,the top part is a triangle with the base of 3.2m and height of 2.2m. since the triangle 8s is a right angle triangle. we use Pythagoras theorem to solve for the hypotenus

Final answer:

The length of the wire connecting the tops of two poles of heights 3.8m and 6m, and spaced 3.2m apart is approximately 3.9 meters when calculated using the Pythagorean theorem.

Explanation:

To calculate the length of the wire connecting the tops of two poles of different heights, we can use the Pythagorean theorem.

This theorem states that in a right angle triangle, the square of the length of the hypotenuse (the wire) is equal to the sum of the squares of the lengths of the other two sides (the distances between the tops of the poles and the ground).

Let's denote:

Pole A as the shorter pole with a height of 3.8m

Pole B as the taller pole with a height of 6m

The distance between the two poles as 3.2m

The difference in height between the two poles is 6m - 3.8m, which is 2.2m. Thus, we have a right triangle where one leg is 3.2m (distance between poles) and the other leg is 2.2m (height difference between poles).

Applying Pythagorean theorem:

c² = a² + b²

c² = 3.2² + 2.2²

c² = 10.24 + 4.84

c² = 15.08

c = √15.08

c ≈ 3.9m

Therefore, the length of the wire is approximately 3.9 meters.

Answer: Lucie is 8 and her brother is 13

Step-by-step explanation: the only possible way for Lucie to be half her brother's age while being 5 years younger at the same time, is if she's 5 and he's 10. that's how old they were 3 years ago. now you just add 3 to 5 and 10 to find their current ages; 5+3=8 so Lucie is 8, and 10+3=13 so her brother is 13.

                                                             :)

Answer:

 Lucie is 8 and her brother is 13

Step-by-step explanation:

Lucie is 5 years younger than her brother. Three years ago, Lucie was twice younger than her brother.

Let L be the Lucie age

and B be the brothers age

Lucie is 5 years younger than her brother

L= B-5

Three years ago, Lucie age is L-3

brother is B-3

Lucie was twice younger than her brother.

2(L-3)= B-3

Plug in B-5 for L

2(B-5-3)= B-3

2B - 16= B-3

Subtract B from both sides

B - 16 = -3

Add 16 on both sides

B= 13

Age of brother = 13

Age of Lucie = brother -5 = 13-5 = 8

For a prime number m, the only factors of m x m would be 1, m, and [tex]m^2[/tex]

If m is a prime number, the factors of m would be 1 and m itself since prime numbers have no divisors other than 1 and themselves. When you calculate m x m which is [tex]m^2[/tex], the factors list expands slightly but remains quite simple due to the nature of prime numbers.

Answer:

y = -5x + 21

Step-by-step explanation:

The perpendicular slope is opposite of the inverse.  The inverse of 1/5 is 5/1, and the opposite of that is -5/1.

So m = -5.

Then use point-slope form:

y + 4 = -5 (x - 5)

If you wish, convert to slope-intercept form:

y + 4 = -5x + 25

y = -5x + 21

Answer:

C

Step-by-step explanation:

Given that the 2 triangles are similar then the ratios of corresponding sides are equal.

This enables RT to be found, that is

[tex]\frac{4}6}[/tex] = [tex]\frac{10}{RT}[/tex] ( cross- multiply )

4RT = 60 ( divide both sides by 4 )

RT = 15

Hence

perimeter of ΔRST = 6 + 12 + 15 = 33 units

The perimeter of triangle RST which is similar to triangle MNO is: C. 33 units.

The perimeter of a triangle = sum of all its 3 sides.

Since triangles MNO and RST are similar triangles, then their corresponding side lengths are proportional to each other.

This means that:

MN/RS = MO/RT = NO/ST

Find RT using MN/RS = MO/RT:

4/6 = 10/RT

RT = (10×6)/4

RT = 15 units.

Perimeter of triangle RST = RS + ST + RT = 6 + 12 + 15 = 33 units.

Step-by-step explanation:

A valid FICO credit score ranges from 300 to 850. A score outside this range is not valid. Key components of a FICO score include credit mix and the impact of new credit, both accounting for 10% of the score respectively.

When it comes to determining what is not a valid FICO credit score, it's important to understand that FICO scores range from 300 to 850. Any score that is not within this range would be considered invalid. Components that make up a FICO score include payment history, amounts owed, length of credit history, new credit, and credit mix. Credit mix refers to the variety of credit types you have, such as credit cards, retail accounts, installment loans, finance company accounts, and mortgage loans, and makes up 10% of your FICO score. Regarding new credit, opening a new account can temporarily lower your score because it reduces the average age of your accounts, which also accounts for 10% of your FICO score.

Two common myths are that opening a new retail credit card is always good for your credit score and that it hurts your score to comparison shop for loans. In reality, opening a retail credit card can lower your score initially, though responsibly managing your new credit can eventually have a positive effect. When it comes to loan comparison shopping, FICO provides a grace period for hard inquiries that are related, bundling them into a single inquiry if they occur within a 14 to 45-day span, depending on the type of credit. This is designed to not penalize consumers who are responsibly shopping for the best rates.

Answer:

The ratio of flour to sugar is 2:1

Step-by-step explanation:

Let f = weight of a bag of flour

Let s = weight of a bag of sugar

3f+2s = 32

4f = 32

We have 2 equations and 2 unknowns, we can solve

4f=32

Divide by 4

4f/4 = 32/4

f = 8

Each bag of flour weights 8 pounds

Substitute this back into the first equation

3(8) +2s = 32

24+2s = 32

Subtract 24 from each side

24-24 +2s =32-24

2s = 8

Divide by 2

2s/2 = 8/2

s = 4 pounds

Flours weighs 8 pounds and sugar weights 4 pounds

We want the ratio of flour to sugar

Flour: sugar

8:4

We can divide each side by 4

Answer:

[tex]r= 2(cos(\theta) + 3sin(\theta))[/tex]

Step-by-step explanation:

To convert an equation of rectangular shape to polar form use the following equivalences

[tex]x=rcos(\theta)[/tex]

[tex]y=rsin(\theta)[/tex]

[tex]x^2 + y^2=r^2[/tex]

In this case we have the following equation.

[tex](x-1)^2 + (y-3)^2=10[/tex]

First we expanded the expression

[tex](x-1)^2 + (y-3)^2=10\\\\(x^2 -2x +1) +(y^2 -6y + 9) = 10\\\\\\x^2 +y^2 -2x -6y = 10-9-1\\\\x^2 +y^2 -2x -6y = 0[/tex]

Now we know that [tex]x^2 + y^2=r^2[/tex], [tex]x=rcos(\theta)[/tex] and [tex]y=rsin(\theta)[/tex]

So

[tex]r^2 -2rcos(\theta) -6rsin(\theta) = 0\\\\r^2 - 2r(cos(\theta) + 3sin(\theta))=0\\\\r^2 = 2r(cos(\theta) + 3sin(\theta))\\\\r= 2(cos(\theta) + 3sin(\theta))[/tex]

Answer:

3 gallons = 12 quarts

$98.52/12 quarts = $8.21/quart

To find the price per quart of a 3-gallon bucket of paint costing $98.52, divide the total cost by the number of quarts in 3 gallons, which is 12. The price per quart comes out to be approximately $8.21.

To find the price per quart for a bucket of paint that costs $98.52 per 3 gallons, we first need to know the number of quarts in 3 gallons. Since 1 gallon equals 4 quarts, 3 gallons will be equal to 3 × 4 quarts, which is 12 quarts.

Therefore, if a 3-gallon bucket costs $98.52, to find the cost per quart, we need to divide the total cost by the total number of quarts.

So, the equation to find the price per quart would be:

Price per quart = Total cost / Number of quarts

Substituting the given values:

Price per quart = $98.52 / 12

Calculating the above, we find:

Price per quart = $8.21 (rounded to two decimal places)

Thus, the price per quart of the paint is approximately $8.21.

Answer:

[tex]f(x) - g(x) = 2(\sqrt{x}-x^3)[/tex]

Step-by-step explanation:

We have the functions

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

The operation [tex]f (x) -g (x)[/tex] is the subtraction of the function f(x) minus the function g(x). Thus

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

Simplifying the expression we have left that:

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

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

[tex]f(x) - g(x) = 2(\sqrt{x}-x^3)[/tex]  Because [tex]x^{\frac{a}{n}} = \sqrt[n]{x^a}[/tex]
