Answer:
C. 24.27 cm
Step-by-step explanation:
sin 65° = opposite ÷ hypotenuse
sin 65° = 22/x
multiply both sides of the equation by x
(sin 65°)x = 22
divide both sides of the equation by sin 65°
x = 22 ÷ sin 65°
punch in 65 sin into your calculator
x = 22 ÷ 0.90631
x = 24.27 cm

Which expression is equivalent to 3^4 ⋅ 3−^9?
Answer:
3^-5 = 1/3^5
Step-by-step explanation:
3^4 ⋅ 3−^9
When multiplying exponents and the bases are the same, we can add the exponents
a^b * a^c = a^ ( b+c)
3^4 ⋅ 3−^9
3^( 4-9)
3^-5
We know that a^ -b = 1/a^b
3^-5 = 1/3^5
Answer:
3^4 times 3^9 = 3^4 times 1/3^9
Step-by-step explanation:
I dont know if this is right there were no answer choices.
