Una pelota sale disparada desde el nivel del suelo, con una velocidad de 40 m/s y un ángulo de elevación de 50°. a) Calcule la altura máxima que alcanza la pelota

Answers

Respuesta:

Los 47.85m

Explicación paso a paso:

Altura máxima = u²sin²Ф / 2g

Dado

velocidad u = 40 m / s

Ф = 50 °

g = 9,81 m / s²

Sustituir'

H = 40²sin²50 / 2 (9,81)

H = 1600 (0,7660) ² / 19,62

H = 1600 (0,5868) /19,62

H = 938,8096 / 19,62

H = 47,85 m

Por lo tanto, la altura máxima es de 47,85 m.

Use the distributive property to expand the following expression. Then combine the like terms.
-3(-2b + 5a + 7n - 10a + 6n +4a)
(please help me!!)

Answers

Answer:

Multiply all values in the bracket by - 3

6b -15a - 21n + 30a - 18n - 12a

Collect like terms

6b - 15a + 30a - 12a - 21n - 18n

6b + 3a - 39n

After the community clean up, the ecology club collected all the empty drink containers. There were 40 more 5 cent deposit containers than 10 cent deposit containers. If the club received $24.80 from the recycling center, how many 5 cent deposit containers did they have?

Answers

they had 288! 24.8/10 is 248, +40 is 288!

The number of 5-cent deposit containers the ecology club collected is 192.

What are the linear equations that represent the question?

a - b = 40 equation 1

0.05a + 0.1b = $24.80 equation 2

Where:

a = number of 5-cent deposit containers b = number of  10- cent deposit containers.

How many  5-cent deposit containers were collected?

The first step is to multiply equation 1 by 0.1

0.1a - 0.1b = 4 equation 3

Add equation 3 and equation 1

$28.80 = 0.15a

a = $28.80 / 0.15

a = 192

Zane needs 20 yards of fencing to go around his rectangular yard. What are possible dimensions for Zane's yard? Select all that apply .

Answers

Answer:

1 yard by 9 yards

2 yards by 8 yards

3 yards by 7 yards

4 yards by 6 yards

Step-by-step explanation:

the perimeter of the rectangular yard needs to be 20 yards

Perimeter of a rectangle = 2 x ( length + width)

20 = 2 x ( length + width)

( length + width) = 20 /2

( length + width) = 10

The sum of the length and width should equal 10

Possible dimensions that would equal 10 are :

1 yard by 9 yards

2 yards by 8 yards

3 yards by 7 yards

4 yards by 6 yards

Answer:

Step-by-step explanation:

To find the area of the square we multiply length and height.

15x12 = 180

For the triangular part of the trapezoid we multiply height by width and divide by 2.

12x7 = 84 / 2 = 42

Add the two sums and we get 222 cm.

180 + 42 = 222

Brice had a number of ethical issues come up in law school involving alleged cheating but managed to graduate because nothing was ever proven. Upon obtaining his law license, Brice enjoyed living "on the edge" and engaged in tactics that were at least questionable. One of his clients was an older gentleman, Sam, with significant assets and significant legal issues involving a messy divorce stemming from his involvement with a local dog groomer, Susie. Brice told Sam that he felt certain that he could arrange matters so that Sam could live happily in the Caribbean with Susie but that, in addition to paying a hefty legal fee, Sam would need to name Brice as a significant beneficiary in his will and give Brice power of attorney over his assets. Sam agreed to do so. He gave Brice power of attorney and changed his will to reflect that upon his death, Brice would receive half his estate. The other half went to Susie. Sam also paid the hefty legal fee Brice demanded. At that point, Brice agreed to proceed with negotiations in the divorce. Shortly after the divorce, Sam had an unexpected heart attack and died immediately. Susie, the executor of the will, told Brice that she was reporting him to the state bar association and that he was not entitled to any assets from the estate. Brice told Susie that he knew that Susie had failed to pay income tax for all her dog grooming and that he was reporting her unless she kept her mouth shut and consented to the terms of the contract. Brice also said that in return for keeping his mouth shut, he wanted additional sums purportedly for his work on Sam's divorce. Assuming that Sam had paid all amounts validly due from the divorce proceeding, which of the following is true regarding Brice's attempt to obtain additional fees? A. Brice has caused Susie to experience duress. B. Brice has unduly influenced Susie. C. Brice has caused Susie to experience duress and unduly influenced Susie. D. Brice has committed intentional wrongful disclosure. E. Brice is not guilty of anything, so long as he used no physical force to obtain Susie's agreement. What is the area of the triangle??
