Answer:

Step-by-step explanation:

-3 + 4i

value = square( (-3)^2 + (4i)^2 ) = sqr(9 + 16) = sqr(25) = 5

The absolute value is like the Pythagoras theorem

Answer:

The answer to your question is F = 78.8

Step-by-step explanation:

Equation

$C = \frac{5}{9} (F - 32)$

Multiply both sides by 9

$9C = \frac{5(9)}{9} (F - 32)$

Simplify

$9C = 5(F - 32)$

Divide both sides by 5

$\frac{9}{5} C = \frac{5}{5} (F - 32)$

Simplify

$\frac{9}{5} C = F -32$

Add 32 in both sides

$\frac{9}{5} C + 32 = F - 32 + 32$

Simplify (Inverse)

$\frac{9}{5} C + 32 = F$

Substitute to find F

$\frac{9}{5} (26) + 32 = F$

Simplify

F = 46.8 + 32

Result

F = 78.8

Write an explicit formula for then th an. term of the sequence 45, 15,5. ....

7nadin3 [17]

Answer:

The sequence above is a geometric sequence

For an nth in a geometric sequence

$u(n) = a {r}^{n - 1}$

where n is the number of terms

a is the first term

r is the common ratio

From the question

a = 45

r = 15 / 45

The explicit formula for the sequence is

U(n) = 45(1/3)^n-1

Hope this helps you
