Answer:

The correct answer is D. The simplified form of the expression 7^4 is 2,401.

Step-by-step explanation:

7 ^ 4, that is, the exponentiation of 7 to the fourth power, implies the continuous multiplication of the number 7 for 4 times. Therefore, this number will appear 4 times in a multiplication, whose result will be said number exposed to the fourth power.

Simplified, this operation translates into 7x7x7x7, whose result is 2,401.

Write and graph the inverse variation in which y = 8 when x = –4.

sweet-ann [11.9K]

For this case we have that an inverse variation in a function is given by:
$y = k / x
$
For this case, we must find the value of the constant k.
To do this, we substitute the values of x = -4, y = 8.
We have then:
$8 = k / -4
$
Clearing k we have:
$k = (8) * (- 4)

k = -32$
Substituting the value of k we have that the inverse variation is:
$y = -32 / x
$
Note: see attached image.
Answer:
$y = -32 / x
$
See attached image.

Prove that √2 + √3 is irrational

Vika [28.1K]

Step-by-step explanation:

Let √2 + √3 be a / b.

a and b are co - primes.

a and b have 1 as a common factor.

√2 + √3 = a / b

( √2 + √3 )^2 = ( a / b )^2

(√2)^2 + (√3)^2 + 2.√2.√3 = a^2 / b^2

2 + 3 + 2.√2.√3 = a^2 / b^2

5 + 2.√2.√3 = a^2 / b^2

2.√2.√3 = ( a^2 / b^2 ) - 5

2.√2.√3 = ( a^2 - 5b^2 ) / b^2

√2.√3 = ( a^2 - 5b^2 ) / 2b^2

a and b are not co - primes, as they more than 1 as a common factor.

So,

√2 + √3 is irrational.

Hence, proved.
