The volume of the dilated prism is calculated to be considering scale factor for the area as well as the height is 7558272 cm³.

The scale factor in the dilation of a mathematical object determines how much larger or smaller the image will be (compared to the original object).

Given that

The base area of prism = 8 cm²

Height of the prism = 6

Scale factor = 54

So enlarged area =( scale factor )² * previous area = 54²* 8 = 23328 cm²

Enlarged height = 54*6= 324 cm

Enlarged volume = enlarged area* enlarged height = 7558272 cm³

Thus, the volume of the dilated prism is 7558272 cm³.

total 2 days = $181

Step-by-step explanation:

Answer:

Total cost for two days for the n members of the club = 155 + 27 n

Step-by-step explanation:

Total number of persons = n

The first day the members paid $60 for transportation plus $15 per ticket to the planetarium.

Day 1 cost = 60 + 15 x n = 60 + 15 n

The second day they paid $95 for transportation plus $12 per ticket to the geology museum.

Day 2 cost = 95 + 12 x n = 95 + 12 n

Total cost = Day 1 cost + Day 2 cost

Total cost = 60 + 15 n + 95 + 12 n = 155 + 27 n

Total cost for two days for the n members of the club = 155 + 27 n

The true condition about the dependent events, P(B|A) is not equal to P(B).

Dependent events in probability mean events whose occurrence of one affect the probability of occurrence of the other.

Two events are said to be dependent if the outcome or occurrence of the first affects the outcome or occurrence of the second so that the probability is changed.

Also, Two events are said to be independent if the outcome or occurrence of the first does not affect the outcome or occurrence of the second so that the probability is not changed.

For independent events: P(A and B) = P(A) x P(B).

Recall that P(B|A) = P(A and B) / P(A) = P(A) x P(B) / P(A) = P(B).

Therefore, for dependent events, P(B|A) is not equal to P(B).

Answer:

(4k^2+7)(7k+6)

Step-by-step explanation:

1. group the first two terms (28k^3-24k^2). The greatest common factor is 4k^2. If you factor that out you get 4k^2(7k-6)

2.When you group the last two terms (49k-42). you can factor out a 7.

7(7k-6).

3. There is a (7k-6) in both sections so you can combine all the terms.

4k^2(7k-6) 7(7k-6) becomes (4k^2)(7k-6)

Step-by-step explanation:

For the 7x8, I'm not including x1/2 also because if we do it once without the x1/2, then it will take it for 2 triangles, and that's what we have here.

So hence, the area of the trapezoid is 80sq.units

Answer:

Step-by-step explanation:

The slope of a line on a graph is found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

Ernest used (x1, y1) = (15, 450) and (x2, y2) = (60, 900) to fill values into this formula. In doing so, he got ...

  m = (900 -450)/(60 -15) = 450/45 = 10

This is an appropriate use of the formula, so gave Ernest the correct answer.

Answer:

the 30th term of the given linear sequence is -63.

Step-by-step explanation:

The given sequence is in arithmetic progression whose difference is given by:

-7 - (-5) = d

d = -2

The nth term in the arithmetic progression is given by the formula:

where 'n' is the number of terms, 'a' is the first term,  is the nth term, and 'd' is the difference.

Now, substitute the known terms in the above formula.

So, the 30th term of the given linear sequence is -63.

The percentage reduction is 20% if the cost of a garment was determined to be $12. 50.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

The cost of a garment was determined to be $12. 50. You have been instructed to lower the cost to $10 per garment.

The difference in cost = 12.50 - 10

The difference in cost = $2.50

The percentage reduction = (2.50/12.50)100

The percentage reduce = 20%

Thus, the percentage reduction is 20% if the cost of a garment was determined to be $12. 50.

We are provided that [tex]{\sf \sin (64^{\circ})=p}[/tex] and we have to find the value of [tex]{\sf 8\sin (16^{\circ})\cdot \cos (16^{\circ})\cdot \cos (32^{\circ})}[/tex] . But let's recall a identity which is gonna be very helpful to do this question i.e

Now , coming back on the question ;

[tex]{:\implies \quad \sf 8\sin (16^{\circ})\cdot \cos (16^{\circ})\cdot \cos (32^{\circ})}[/tex]

[tex]{:\implies \quad \sf 4\{ 2\sin (16^{\circ})\cos (16^{\circ})\}\cos (32^{\circ})}[/tex]

Using the above identity ;

[tex]{:\implies \quad \sf 4\sin (32^{\circ})\cos (32^{\circ})}[/tex]

[tex]{:\implies \quad \sf 2\{2\sin (32^{\circ})\cos (32^{\circ})\}}[/tex]

Again using the same identity ;

[tex]{:\implies \quad \sf 2\sin (64^{\circ})}[/tex]

Putting the given value of [tex]{\sf \sin (64^{\circ})}[/tex]

[tex]{:\implies \quad \sf 2p}[/tex]

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{8\sin (16^{\circ})\cdot \cos (16^{\circ})\cdot \cos (32^{\circ})=2p}}}[/tex]

Proof of the above identity :-

We know that ;

[tex]{\quad \boxed{\sf \sin (A\pm B)=\sin (A)\cos (B)\pm \cos (A)\sin (B)}}[/tex]

So ;

[tex]{:\implies \quad \sf \sin (A+ B)=\sin (A)\cos (B)+\cos (A)\sin (B)}[/tex]

Putting [tex]{\sf A=B=\theta}[/tex] ,

[tex]{:\implies \quad \sf \sin (\theta+ \theta)=\sin (\theta)\cos (\theta)+\cos (\theta)\sin (\theta)}[/tex]

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{\sin (2\theta)=2\sin (\theta)\cos (\theta)}}}[/tex]

Hence , Proved :D
