Answer:

#3: 81

Step-by-step explanation:

I haven't done this type of math in a while so I'm unsure about #1 and #2, but #3 is 81.

3^4 = 3 × 3 × 3 × 3

3^4 = 9 × 3 × 3

3^4 = 27 × 3

3^4 = 81

PLLSSS REALLY URGENT <br> If g(x)=3x+4, determine n that g(-3)=g^-1(n).

grigory [225]

Answer:

we have:

g(-3) = 3.(-3) + 4 = -5

$g {}^{ - 1} (n) = \frac{1}{3n + 4}$

because

$g( - 3) = g {}^{ - 1} (n)$

$- 5 = \frac{1}{3n + 4} \\ \\ < = > - 5(3n + 4) = 1 \\ \\ < = > - 15n - 20 = 1 \\ \\ < = > n = \frac{ - 21}{15} \\ \\ < = > n = \frac{ - 7}{5}$

A thermometer gives a reading of 26 degrees Celsius. Use the formula c =5/9(f-32). Write the inverse function and use it to find

guajiro [1.7K]

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
