Answer:

The HCF of [tex]a=2^1 \cdot 3^4 \cdot 5^1[/tex] and [tex]b = 2^3 \cdot 3^2 \cdot 5^2[/tex] is [tex]90[/tex].

Step-by-step explanation:

To calculate the HCF of two numbers given their prime factorization, we take the lowest exponent of every prime when comparing the two numbers.

So the HCF of [tex]a=2^1 \cdot 3^4 \cdot 5^1[/tex] and [tex]b = 2^3 \cdot 3^2 \cdot 5^2[/tex] is [tex]2^1 \cdot 3^2 \cdot 5^1 = 90[/tex].

Simplify and write the trigonometric expression in terms of sine and cosine:
tan u + cot u = 1/f(u)

Answers

Answer:

we have the expression as;

1/sin u cos u

Step-by-step explanation:

tan u = sin u/cos u

cot u = cos u/sin u

Thus;

sin u/cos u + cos u/sin u

The lcm is sin u cos u

Thus, we have that;

(sin^2 u + cos^2 u)/sin u cos u

But ; sin^2 u + cos^2 u = 1

so we have ;

1/sin u cos u

The requested trigonometric expression in terms of sine and cosine is;

[tex]f(u) = \frac{1}{ \frac{sinu}{cosu} + \frac{cosu}{sinu} } [/tex]

Trigonometric expressions:

We must remember,

tan u = sin(u)/cos(u)

and cot u = cos(u)/sin(u).

Therefore we have;

sin(u)/cos(u) + cos(u)/sin(u) = 1/f(u)

By Cross-product; we have;

[tex]f(u) = \frac{1}{ \frac{sinu}{cosu} + \frac{cosu}{sinu} } [/tex]

Therefore, the required function, f(u) in terms of sin u and cos u is as represented above.

Answer:

x = 18.7

Step-by-step explanation:

Gerald's answer is almost correct.

He just needs to switch the 14 and the x.

it should be

24/x = 18/14

solve for x by cross multiplication

18x = (24)(14)

18x = 336

x = 18.7

a farmer has enough food to feed 50 animals in his cattle for 15 days . how long will the food last if there are 25 more animals in his cattle?

Answers

Answer:

The food will last for 10 days

Step-by-step explanation:

Proportions

The amount of food the farmer needs to feed his animals is proportional to the number of animals and to the number of days they are fed.

This can be written as:

Food=k*N*D

Where k is a constant, N is the number of animals and D is the number of days.

We know that the farmer has enough food to feed N=50 animals for D=15 days, thus:

Food=k*50*15=750k

If the same amount of food is used for 50+25=75 animals, then:

750k=k*75*D

Simplifying:

750=75*D

Dividing by 75:

D=10

The food will last for 10 days

Select the factors of the equation

[tex]x^2 - x - 56 = 0[/tex]

Expand the equation

Parallelogram R S T U is shown. Diagonals are drawn from point R to point T and from point U to point S and intersect at point V. The length of line segment U V is (x + 3) meters and the length of line segment V S is (2 x minus 7) meters. In parallelogram RSTU, what is SU? 10 m 13 m 23 m 26 m

Answers

Answer:

26m

Step-by-step explanation:

The diagonals of a parallelogram bisects each other. Hence the length of UV is equal to the length of VS

UV = VS

x+3 = 2x-7

x-2x = -7-3

-x = -10

x = 10

Get SU

SU = UV+VS

SU = x+3+2x-7

SU = 3x-4

Substitute x=10 into the expression

SU = 3(10)-4

SU = 30-4

SU = 26m

Length of SU is 26m

26m i just did it on edg

Step-by-step explanation:

Emir flew home from vacation with a heavy bag. With the first airline he flew, Emir had to pay $20 to check his bag, plus $10 for every pound that his bag was over the weight limit. The next flight was with another airline that had the same weight limit. Emir had to pay $5 per pound that his bag was over the weight limit, in addition to the checked bag fee of $30. By coincidence, the fees ended up being the same with both airlines. How large was each airline's fee?

Answers

Answer:

$27.5

Step-by-step explanation:

Let

x = pound over weight limit

Airline 1 = 20 + 10x

Airline 2 = 5 + 30x

Equate the fees

20 + 10x = 5 + 30x

20 - 5 = 30x - 10x

15 = 20x

x = 15/20

x = 0.75 pounds

How large was each airline's fee?

Airline 1 = 20 + 10x

= 20 + 10(0.75)

= 20 + 7.5

= $27.5

Airline 2 = 5 + 30x

= 5 + 30(0.75)

= 5 + 22.5

= $27.5

Proofreading Task #2: "Native Americans & Horses"Identify and correct 11 total grammar, spelling, and/or punctuation errors in the passage,The first horses lived 4 million years ago in North America. From there, they crossed aLand bridge into Asia and Europe. The horses in Europe and Asia continued to thrive,but the horses in North America went extinct. No one is quiet sure why they died outbut scientists think it might be because of climate change or overhunting by earlyhumans.Because horses had been extinct for so long, Native Americans did not know whathorses were until they were bringed over by the Spanish. When the conquistadorsfirst came to South America, people thought that the horses were giant dogs. Later,in 1680, Pueblo Native Americans fought the Spanish and pushed him out of newMexico. Afterwards, the Pueblo were able to use and trade horses. These horsesspread up the western part of what is now the United States, changing the lives ofthe people there.The Native Americans on the western Great Plains captured and trained the Spanishhorses that were running through the Great Plains in wild herds. On horseback,Native Americans were able to move quick over long distances. This made it easier tohunt bison, trading, and expand their territory. Not only were the bison a source offood, and they could also be used to create buffalo robes. Native Americans couldtrade these robes with the white settlers for goods, like blankets and guns, Horsesalso made life easyer for women. Before, women had to carry their familiespossessions from camp to camp. Now, horses could take that load. By mastering theart of horse riding, tribes were able to gain great power and wealth.
