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: 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

Answer:

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.

Answer:  

-2x^3 + 2x^(1/2)

Step-by-step explanation:

step one- plug in the values of each in f(x) - g(x)

x^(1/2)-x - (2x^3-×^(1/2)-x) ; g(x) is in parentheses bc we need to distribute the negative

x^(1/2)-x-2x^3 + x^(1/2) + x ; combine like terms (letters with the same exponents) ; the x's cancel, and the x^(1/2) + x^(1/2) combine to form 2x^(1/2); the -2x^3 remains

you should get

-2x^3 + 2x^(1/2)

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]

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]

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]

Answer:

( 3 × 2 ) × 7

Step-by-step explanation:

To find the volume of a rectangular prism you have to do

Length × Width × Height

3 × 2 × 7 = 42 yd³

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.

Those would be all the factors of [tex]m^2[/tex] when m is a prime number.

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 )

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)

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:

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.

As it is given in the question that the person is charged based on the extra miles over the speed limit. If the speed limit was 50 mph and the driver was driving at 61 mph, then the number of miles over the speed limit

=> 61-50

=> 11 miles

So, we have to look for 11 on x-axis and then we look for the y-axis's intercept that intersects with 11.

So, in the given graph, the value 11 of x-axis intercepts with the $150 on y-axis.

So the fine will be $150 ..
