The correct answer is false.

Step-by-step explanation:

Answer:

6.25 m²

Step-by-step explanation:

The area of the small mural is 1.5 times greater than that of the small mural.

That means the area of the large mural is 2.5 times the area of the small mural.

Area = 2.5 × 2.5 m² = 6.25 m²

The area of the large mural is 6.25 m².

Answer:

A) A sequence is an ordered list of numbers; B) The terms an approach 8 as n becomes large; C) The terms an become large as n becomes large.

Step-by-step explanation:

A) A sequence is an ordered list of numbers, letters, colors, or other objects.  It is essentially a pattern.

B) [tex]n \to \infty (a_n) = 8[/tex] shows n approaching infinity.  This means n, the term numbers of [tex]a_n[/tex], get large.  The fact that it equals 8 means that the terms of the sequence approach 8 as n gets large.

C) [tex]n \to \infty (a_n) = \infty[/tex] shows n approaching infinity.  This means n, the term numbers of [tex]a_n[/tex], get large.  The fact that it equals infinity means that the terms of the sequence become large as n becomes large.

Answer:

  A.  2

Step-by-step explanation:

There is a vertical asymptote where the denominator is zero. (x-2) is zero when x=2.

Answer:

option A

{1, 2, 4, 7, 9}

Step-by-step explanation:

The domain of a function is the complete set of possible values of the independent variable. Mostly it is 'x' values.

In the figure the tail of arrow represent values of domain and head of arrow represent values of range.

So,

{1, 2, 4, 7, 9} is the domain of G(x) and {3, 5, 8} is the range

the original price would have been $36

Final answer:

The original price of a pair of shoes on sale for $27 after a 25% discount is calculated by dividing the sale price by 0.75, which gives us $36 as the original price.

Explanation:

To find the original price of a pair of shoes if the sale price is $27 after a 25% discount, we need to reverse the discount process. A 25% discount means that the sale price is 75% of the original price, since 100% - 25% = 75%. We can represent the original price with the variable 'P', and the equation we use is 0.75P = $27.

To find P, we divide both sides of the equation by 0.75:

P = $27 / 0.75

P = $36

Therefore, the original price of the pair of shoes was $36.

Answer:

Option A. [tex]65\ ft^{2}[/tex]

Step-by-step explanation:

we know that

In a right triangle the legs are perpendicular

so

the area is equal to multiply the two legs and  divide by two

[tex]A=\frac{1}{2}(10)(13)=65\ ft^{2}[/tex]

Final answer:

To find the area of a right triangle with legs of length 10 feet and 13 feet, you multiply the lengths and divide by 2. The calculated area is 65 square feet, making option A the correct answer.

Explanation:

The question is asking about the area of a right triangle. To find the area of any triangle, you use the formula A = (base × height) / 2. Since a right triangle has two legs that are perpendicular to each other, these legs can be considered as the base and the height of the triangle. In our case, we have legs of lengths 10 feet and 13 feet, so applying the formula:

A = (10 ft × 13 ft) / 2
= (130 ft²)/2
= 65 ft²

So, the area of the right triangle is 65 square feet, which corresponds to option A.

Answer:

[tex]\large\boxed{A\subseteq B}[/tex]

Answer:

[tex]\large\boxed{D)\ \dfrac{8}{7}}[/tex]

Step-by-step explanation:

[tex]8\left(-\dfrac{2}{7}\right)\left(-\dfrac{1}{2}\right)\\\\\text{the product of two negative numbers is positive}\\\\8\cdot\dfrac{2\!\!\!\!\diagup^1}{7}\cdot\dfrac{1}{2\!\!\!\!\diagup_1}=8\cdot\dfrac{1}{7}\cdot\dfrac{1}{1}=\dfrac{8}{7}[/tex]

The product of (3x - 7y)^2 is found by squaring the binomial using the FOIL method, which leads to 9x^2 - 42xy + 49y^2.

To find the product of (3x \\- 7y)^2, you must square the binomial. This means you will multiply the binomial by itself. When you square a binomial, you use the FOIL method (First, Outer, Inner, Last) to multiply the terms.

First: (3x)(3x) = 9x^2
Outer: (3x)(-7y) = -21xy
Inner: (-7y)(3x) = -21xy
Last: (-7y)(-7y) = 49y^2

Combine like terms (the Outer and Inner terms in this case).

9x^2 - 21xy - 21xy + 49y^2 = 9x^2 - 42xy + 49y^2

Thus, the product of (3x - 7y)^2 is 9x^2 - 42xy + 49y^2.

∠LMN is a right angle

If we want to prove that two right triangles are congruent by knowing that the corresponding hypotenuses and one leg are congruent, we begin as follows:

leg MN of both triangle is equal.

HL stands for "Hypotenuse, Leg" (the longest side of a right-angled triangle is called the "hypotenuse", the other two sides are called 'legs', or 'base' and 'height'.

It means we have two right-angled triangles with

Since ∠ LMN and ∠KMN are right angle , the hypotenuse LN and and one leg LN of one right-angled triangle LMN are equal to the corresponding hypotenuse KN and leg MN of another right-angled triangle MKN, hence the two triangles are congruent.

Answer:

yes, distance travel in first 8 minute is 1.75 time higher than second 8 minutes

Step-by-step explanation:

Given data:

speed in first 8 minute is 1.75 faster than 2nd 8 minutes.

from the above information we can say that time remain same in both situation and we know that speed is given as

speed = distance / time

since time remain same in both case. Therefore speed is directly proportional distance having time as constant

As speed is 1.75 times higher in first 8 minutes than second 8 minutes therefore distance also behave in the same way i.e distance travel in first 8 minute is 1.75 time higher than second 8 minutes

[tex]\large\boxed{C=22\pi y\ ft}[/tex]

Step-by-step explanation:

The formula of an area of a circle:

[tex]A=\pi r^2[/tex]

r - radius

The formula of a circumference of a circle:

[tex]C=2\pi r[/tex]

We have the area of a circle

[tex]A=121y^2\pi ft^2[/tex]

Substitute to the formula and solve for r:

[tex]\pi r^2=121y^2\pi[/tex]            divide both sides by π

[tex]r^2=121y^2\to r=\sqrt{121y^2}\\\\r=11y\ ft[/tex]

Put the value of r to the formula of a circumference:

[tex]C=2\pi(11y)=22y\pi ft[/tex]

Answer:

  the limit is 1/16

Step-by-step explanation:

At x=4, the function is indeterminate: 0/0, so l'Hopital's rule can be used to find the limit. Differentiating numerator and denominator, you get ...

  lim = (1/√x) / (2x)

Evaluating this at x=4 gives (1/2)/8 = 1/16.

The limit as x approaches 4 is 1/16.

Answer:

1. [tex]\cot B=\frac{5}{12}[/tex]

2. [tex]\sin2A=\frac{24}{25}[/tex]

3. [tex]\cos(\frac{5\pi}{6}+B )=-\frac{5}{26}(\sqrt{3}+1)[/tex]

4. [tex]\tan(A-\frac{\pi}{4} )=-\frac{1}{7}}[/tex]

Step-by-step explanation:

If  [tex]\sin A=\frac{3}{5}[/tex] and [tex]\cos B=\frac{5}{13}[/tex], then we can use the Pythagorean identity to find [tex]\cos A[/tex] and [tex]\sin B[/tex].

[tex]\sin^2A+\cos^2A=1[/tex]

[tex](\frac{3}{5} )^2+\cos^2 A=1[/tex]

[tex]\frac{9}{25}+\cos ^2A=1[/tex]

[tex]\cos^2 A=1-\frac{9}{25}[/tex]

[tex]\cos^2 A=\frac{16}{25}[/tex]

[tex]\cos A=\pm \sqrt{\frac{16}{25}}[/tex]

Since A is in quadrant I,

[tex]\cos A=\sqrt{\frac{16}{25}}[/tex]

[tex]\cos A=\frac{4}{5}[/tex]

Also;

[tex]\sin^2B+\cos^2B=1[/tex]

[tex](\frac{5}{13} )^2+\sin^2 B=1[/tex]

[tex]\frac{25}{169}+\sin ^2B=1[/tex]

[tex]\sin^2 B=1-\frac{25}{169}[/tex]

[tex]\sin^2 B=\frac{144}{169}[/tex]

[tex]\sin B=\pm \sqrt{\frac{144}{169}}[/tex]

Since A is in quadrant I,

[tex]\sin B=\sqrt{\frac{144}{169}}[/tex]

[tex]\sin B=\frac{12}{13}[/tex]

This implies that;

[tex]\cot B=\frac{\cos B}{\sin B}[/tex]

[tex]\cot B=\frac{\frac{5}{13} }{\frac{12}{13} }[/tex]

[tex]\cot B=\frac{5}{12}[/tex]

[tex]\sin2A=2\sin A \cos A[/tex]

[tex]\sin2A=2\times \frac{3}{5} \times \frac{4}{5}[/tex]

[tex]\sin2A=\frac{24}{25}[/tex]

[tex]\cos(\frac{5\pi}{6}+B )=\cos(\frac{5\pi}{6})\cos(B )-\sin(\frac{5\pi}{6})\sin(B)[/tex]

This implies that;

[tex]\cos(\frac{5\pi}{6}+B )=\cos(\frac{5\pi}{6})\times \frac{5}{13}-\sin(\frac{5\pi}{6})\times \frac{5}{13}[/tex]

[tex]\cos(\frac{5\pi}{6}+B )=-\frac{\sqrt{3}}{2}\times \frac{5}{13}-\frac{1}{2})\times \frac{5}{13}[/tex]

[tex]\cos(\frac{5\pi}{6}+B )=-\frac{5}{26}(\sqrt{3}+1)[/tex]

[tex]\tan(A-\frac{\pi}{4} )=\frac{\tan A-\tan \frac{\pi}{4} }{1+\tan A \tan \frac{\pi}{4}}[/tex]

But; [tex]\tan A=\frac{\sin A}{\cos A}[/tex]

[tex]\tan A=\frac{\frac{3}{5} }{\frac{4}{5} }=\frac{3}{4}[/tex]

[tex]\tan(A-\frac{\pi}{4} )=\frac{\frac{3}{4}-\tan \frac{\pi}{4} }{1+\frac{3}{4} \tan \frac{\pi}{4}}[/tex]

Simplify;

[tex]\tan(A-\frac{\pi}{4} )=\frac{\frac{3}{4}-1 }{1+\frac{3}{4}}[/tex]

[tex]\tan(A-\frac{\pi}{4} )=-\frac{1}{7}}[/tex]

Answer:

A

Step-by-step explanation:

The first "circle" is the "domain", which is the set of x values of the function.

The second "circle" is the "range", which is the set of y values of the function.

The range is 4, 7, 9. There are a few x values that match to same y-values but the range is basically the three numbers, 4, 7, and 9.

Option A, {4,7,9} is the correct answer.
