Answer:
v = 25.98
Step-by-step explanation:
You could do this a number of ways. Some are much longer than others. The shortest way is to use the tangent.
Formula
Tan(theta) = opposite / adjacent
Givens
Theta = 30o
Opposite = 15 km
Adjacent = x
Solution
tan(30) = 15 / v Multiply both sides by v
v*tan(30) = 15 Divide by tan(30)
v = 15/tan(30)
tan(30) = 0.5774
v = 15 / 0.5774
v = 25.98
Answer:
b and g
Step-by-step explanation:
a. is y = 0³ = 0
b. is y = ln(0), which is undefined because ln(x) is only defined for x > 0
c. is y = 1 / (1 + e^-0) = 1 / (1 + 1) = 1/2
d. is y = 0
e. is y = 0² = 0
f. is y = sin(0) = 0
g. is y = 1/0, which is undefined because division by 0 is undefined
h. is y = e^0 = 1
i. is y = |0| = 0
j. is y = √0 = 0
10+10 = 20
20 x 2= 40
The answer is 40
Answer:
45.5
Step-by-step explanation:
First you would find 1/3 third of 10.50 and it is 3.5, you would then do 10.50 x 4 since it said 10.50 per half a yard, so you would do times 4 and you would get 42, you would then add 42 + 3.5 which equals 45.5.
B is your awnser! sorry if im wrong my calc shows its without a - symbol
