The answer is {4, 6, 8, 10, 12} - or B
Answer: 1) A
2) yes
Step-by-step explanation:
Expression A = (18500)(0.96)^3t, implying that at t = 1/3 years = 4 months, the exponent will be 1, meaning that the value will be multiplied by 0.96 (which is a decrease of 4%). This fits the third choice.
Expression B has a factor of (1.18)^t/3, implying that at t = 3 years, the exponent will be 1, meaning that the value is multiplied by 1.18, which is a growth of 18%. This also fits the third choice.
Answer: The ladder should be at least 34 feet long (approximately)
Step-by-step explanation: Please refer to the diagram attached for details.
The chimney is depicted as line AB (33 ft). The distance from the base of the chimney to the ladder is depicted as line BC (3 ft). The ladder is placed such that it forms an angle of 75.5 degrees with the floor. Hence the required length of the ladder needed is shown in the diagram as line AC (line b). The resulting diagram now has an opposite (33 ft) and an hypotenuse (b) which is yet unknown.
To calculate line b, we shall apply the trigonometric ratio as follows;
SinC = opposite/hypotenuse
Sin 75.5 = 33/b
By cross multiplication we now have
b = 33/Sin 75.5
b = 33/0.9681
b = 34.087
Therefore the required length of the ladder is approximately 34 feet.
Answer:
90- 54w
Step-by-step explanation:
First, distribute multiply 18×5 which is 90.
Then, 18×3w which is 54 and bring the w with it.
Hope this helps :)
