<h2>Answer:</h2>

A contradiction is always false.

<h2>Step-by-step explanation:</h2>

In mathematics a contradiction means that the assumptions that we have started with to prove with something leads to a negation of the given statement.

In logic a contradiction  is a statement which is opposite to one which is already formed i.e. it is the act of contradicting.

       Hence, contradiction is always false.

What is the general equation of a sine function with an amplitude of 6, a period of StartFraction pi Over 4 EndFraction, and a h
Katen [24]

Answer:

C: y = 6 \sin (8(x-\frac{\pi}{2} ))

Step-by-step explanation:

Amplitude is changed by multiplying the entire trig function by a number, by default the amplitude is 1, so multiplying by 6 is necessary; eliminate A and B

Horizontal shift is going through the x axis, so it must be subtracted from the x value. This is only seen in choice C of the remaining answers.

Calculating the period isn't necessary because we already found the right answer but in case you need it in the future; the period is by default 2pi, to get to pi/4, it had to be 8 times smaller, so multiplying x and translations on x by 8 will get you the correct period.

The hypotenuse of a 45 degrees -45 degrees -90 degrees triangle measures 10 root of 5 in.
juin [17]

Answer:

5\sqrt{10}\ in

Step-by-step explanation:

<u><em>The question is </em></u>

Find the measure of the legs

we know that

In a 45 degrees -45 degrees -90 degrees triangle, the measure of the legs are equal

Let

a ----> the measure of one leg

Applying the Pythagorean Theorem

(10\sqrt{5})^2=a^2+a^2

solve for a

500=2a^2

Divide by 2 both sides

a^2=250

a=\sqrt{250}\ in

Simplify

a=5\sqrt{10}\ in

Ms. Smith and Mr. Roberts are running a race. Ms. Smith runs 8, 305 feet. Mr. Roberts runs 2 miles. How many feet further does M
Tcecarenko [31]

Answer:

Mr. Roberts runs 2,255 more feet then Ms. Smith.

Step-by-step explanation:

So I took 5,280 + 5,280 = 10,560 so now I can just take Ms. Smith's 8,305 and subtract it from 10,560 which gave me 2,255 so Mr. Roberts runs 2,255 more feet then Ms. Smith.

Which expression has a value that is less than the base of that experience?
Rom4ik [11]

Answer:

(B) (\frac{5}{6})^{2}

Step-by-step explanation:

(A) The given expression is: 2^{3}

=8

The value of this expression is 8 which is greater than the base of the expression that is 2.

(B) The given expression is: (\frac{5}{6})^{2}

=\frac{25}{36}

=0.09

The value of this expression is 0.09 which is smaller than the base of the given expression that is 0.83.

(C) The given expression is: 3^{2}

=9

The value of this expression is 9 which is greater than the base of the given expression that is 3.

(D) The given expression is: 4^{4}

=256

The value of this expression is 256 which is greater than the base of the given expression that is 4.

Hence, Option B is correct.
