Answer:
H(t) = 15 -6sin(2.5π(t -0.5))
Step-by-step explanation:
For midline M, amplitude A, period T and time t0 at which the function is decreasing from the midline, the function can be written as ...
H(t) = M -Asin(2π/T(t -t0))
Using the given values of M=15, A=6, T=0.8 and t0 = 0.5, the equation is ...
H(t) = 15 -6sin(2.5π(t -0.5))
1 kilometer =5/3 week
Step-by-step explanation:
Given that the crew paves 3/5 kilometer of a road in 1 week then this can be written as;
3/5 k = 1 week
For 1 kilometer of a road,
3/5k = 1 week
1k=?
perform cross product as;/multiplication equation
1*1 / 3/5
1*5/3
5/3, 1 2/3 weeks
A division equation will be'
3/5 kilometers = 1 week
Divide both sides by 3/5
1 kilometer =5/3 week

Answer: 12.32
Step-by-step explanation:
7.04 divided by 4 = 1.76. 1.76 x 7 = 12.32.
Elsa's answer is incorrect since there is a solution of the given equation. In the given logarithmic problem, we need to simplify the problem by transposing log2(3x+5) in the opposite side. The equation will now be log2x-log2(3x+5)=4. Using properties of logarithm, we further simplify the problem into a new form log (2x/6x+10)=4. Then transform the equation into base form 10^4=(2x/6x+10) and proceed in solving for x value which is equal to 1.667.
