Sinhx = 8/15 what are the other hyperbolic functions?

Answers

cosh^2x - sinh^2x = 1

coshx = sqrt( 1 + sinh^2x)
 
= sqrt(1 + (8/15)^2) = 17/15

for tanh

just divide

sinhx/coshx = tanhx = 8/17

The perimeter of a rectangle is 34 units. Its width is 6.5 units. What is its length?

Answers

If the width is 6.5 then double that to work out the two widths which would be 13. Take that from the perimeter so you're left with 21. Half 21 to work out one length which is 10.5. Length = 10.5

Which are correct statements regarding proofs? Check all that apply. In a paragraph proof, statements and their justifications are written in sentences in a logical order. A two-column proof consists of a list statements and the reasons the statements are true. A flowchart proof gives a visual representation of the sequence of steps without justifications. A paragraph proof is a two-column proof in sentence form. A two-column proof lists only the given information and what is to be proven. A flowchart proof includes a logical series of statements in boxes with connecting arrows.

Answers

Answer:

  1. In a paragraph proof, statements and their justifications are written in sentences in a logical order.
  2. A two-column proof consists of a list statements and the reasons the statements are true.
  3. A paragraph proof is a two-column proof in sentence form.
  4. A flowchart proof includes a logical series of statements in boxes with connecting arrows.

Step-by-step explanation:

The correct statements regarding proofs are :

  1. In a paragraph proof, statements and their justifications are written in sentences in a logical order.
  2. A two-column proof consists of a list statements and the reasons the statements are true.
  3. A paragraph proof is a two-column proof in sentence form.
  4. A flowchart proof includes a logical series of statements in boxes with connecting arrows.

And these two sentences are wrong statements:

  1. A flowchart proof gives a visual representation of the sequence of steps without justifications.
  2. A two-column proof lists only the given information and what is to be proven

The correct statements regarding proofs are;

  • A paragraph proof is a kind of written argument in which claims and their supporting evidence are presented in a series of paragraphs.
  • Statements and their supporting evidence are listed in separate columns in a two-column proof. This is further explained below.
  • A paragraph proof is a two-column proof in sentence form.
  • A flowchart proof includes a logical series of statements in boxes with connecting arrows.

What is proof?

Generally, proofs are simply defined as A piece of proof that proves a claim or assertion to be true.

In conclusion, Proofs are based on communicable facts on a subject.

One angle of an isosceles triangle measures 120°. Which other angles could be in that isosceles triangle? Choose all that apply.20° 70° 80° 30°

Answers

Since an isosceles triangle has two angles that are the same, and one different, the 120 degrees would be the different one. 180-120= 60 degrees 60/2=30 degrees
