Write the expression as the sine, cosine, or tangent of an angle.

erma4kov [3.2K]

Answer:

tan56°

Step-by-step explanation:

The Addition identity for tangent ratio is

tan(x + y) = $\frac{tanx+tany}{1-tanxtany}$ , thus

$\frac{tan24+tan32}{1-tan24tan32}$ = tan(24 + 32)° = tan56°

The temperature in degrees Celsius can be determined using the expression 5 9 (F – 32) where F is the temperature in degrees Fah

Norma-Jean [14]

Answer:

The temperature on Celsius scale for 86 ºF is 30 ºC.

Step-by-step explanation:

Both degrees Celsius and Fahrenheit are relative scales of temperature. The relationship between degrees Fahrenheit and degrees Celsius is summarized by the equation below:

$T_{C} = \frac{5}{9}\cdot (T_{F}-32)$ (1)

Where:

$T_{F}$ - Temperature, measured in degrees Fahrenheit.

$T_{C}$ - Temperature, measured in degrees Celsius.

If we know that $T_{F} = 86\,^{\circ}F$ , then its equivalent temperature on Celsius scale is:

$T_{C} = \frac{5}{9}\cdot (86-32)$

$T_{C} = 30\,^{\circ}C$

The temperature on Celsius scale for 86 ºF is 30 ºC.

12n^2+48n = -n^3-64 factoring polynomial equations

xxTIMURxx [149]

Answer:

Step-by-step explanation:

12n2+48n=−n3−64

Step 1: Subtract -n^3-64 from both sides.

12n2+48n−(−n3−64)=−n3−64−(−n3−64)

n3+12n2+48n+64=0

Step 2: Factor left side of equation.

(n+4)(n+4)(n+4)=0

Step 3: Set factors equal to 0.

n+4=0

n=−4
