| 5x - 6 | = -41....no solution because an absolute value cannot be negative
|7x + 13 | = 27
7x + 13 = 27 -(7x + 13) = 27
7x = 27 - 13 -7x - 13 = 27
7x = 14 -7x = 27 + 13
x = 14/7 -7x = 40
x = 2 x = -40/7
so basically, equation 1 has no solution and equation 2 has 2 solutions
Answer:
Option 2
Step-by-step explanation:
1/4 is equal to .25 or 25/100
Answer:
81.3 feet
Step-by-step explanation:
A shark is swimming 28 feet below sea level. If the angle of depression from a boat on the water is 19 degrees What is the distance between the boat and the shark?
We solve the above question using Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = Angle of depression = 19°
Distance between the boat and the shark = Adjacent = ? = x
Opposite = 28 feet
Hence:
tan 19 = 28/x
Cross Multiply
tan 19 × x = 28
x = 28/tan 19
x = 81.317904575 feet
Approximately = 81.3 feet
The distance between the boat and the shark is 81.3 feet
Answer:
x and y are just varibles
Step-by-step explanation:
It has to go through two steps,
first: works in the morning at 50%
second : overheats rest of the day at 15%
Probability that it will work in the morning and overheats rest of the day is the product of the two probabilities, namely
Probability=0.50*0.15=0.075, or 7.5%.
