Check the picture below.

notice the tickmarks, thus TP = PU and TQ = QS, so the PQ segment is then a midsegment of the larger triangle, and thus the angles it makes on the small one, are exactly the same.

Find the roots of the function f(x) = 3x4 - 48.
Andrew [12]

Answer:

x=\pm 2\text{ or } x = \pm 2i

Step-by-step explanation:

We are given:

0=3x^4-48

Factor:

0=3(x^4-16)

Difference of Two Squares:

0=3(x^2-4)(x^2+4)

Zero Product Property:

(x^2-4)=0\text{ or } x^2+4=0

Solve:

x^2=4\text{ or } x^2=-4

Take the square root. Since we are taking an even-root, it requires plus/minus:

x=\pm 2\text{ or } x = \pm 2i

Which equation is the inverse of 5 y + 4 = (x + 3) squared + one-half?
8_murik_8 [283]

The inverse of the given function is y = √5x + 7/2 - 3

<h3>Inverse of a function</h3>

Given the function expressed below;

5y + 4 = (x+3)² +1/2

5y = (x+3)² - 7/2

y = 1/5(x+3)² - 7/10

Replace y as x

x = 1/5(y+3)² - 7/10

Make y the subject of the formula

5x = (y+3)²- 7/2

(y+3)² = 5x + 7/2

y+3 = √5x + 7/2

y = √5x + 7/2 - 3

Hence the inverse of the given function is y = √5x + 7/2 - 3

When a number is added to 1/5 of itself, the result is 24. The equation that models this problem is n +1/5 n = 24. What is the v
Lady_Fox [76]

For this case we must find the value of n of the following equation:

n + \frac {1} {5} n = 24

Taking common factor "n" from the left side of the equation we have:

n (1+ \frac {1} {5}) = 24\\n \frac {6} {5} = 24

Multiplying by 5 on both sides of the equation:

6n = 120

Dividing between 6 on both sides of the equation:

n = 20

Thus, the value of n is 20.

Answer:

n = 20
