Answer
w=7.6
x=43.7
Step-by-step explanation:
To solve for w you can use Sin(x)=
which would basically be Sin(50)=
then solve. Multiply the ten on both sides so you have 10*Sin(50)=w and your final answer is 7.6
To solve for x you can also use Sin(x)=
then just use Inverse of Sin^-1
The answer is x=43.7
Answer:
B. 6 units
Step-by-step explanation:
I am joyous to assist you anytime.
Think of the 13-ft length of the ladder as the hypotenuse of a right triangle. Represent the horiz. distance from foot of ladder to base of tree by x, or 5 ft.
Represent the vert. dist. from base of tree to top of ladder by y, which is unknown.
Then (13 ft)^2 = (5 ft)^2 + y^2, or
169 ft^2 = 25 ft^2 + y^2. This simplifies to y^2 = 144. Thus y = + 12 feeet.
Note: Please pay attention to your spelling: "lader i up agenst a tree" should be "the top of a 13-ft ladder is placed against a tree."
Answer:
7
Step-by-step explanation:
Given the information from the question:
Next we can use the order of operations to find the value of the expression.
Performing laplace transform of the equation.
sY(s) - y(0) + 6Y(s) = 1/(s-4)
(s+6)Y(s) - 2 = 1/(s-4)
Y(s) = 2/(s+6) + 1/(s-4)(s+6), by partial fraction decomposition
Y(s) = 2/(s+6) + 1/10 * (1/(s-4) + 1/(s+6))
Y(s) = 0.1/(s-4) + 2.1/(s+6)
Performing inverse laplace transform,
y(t) = 0.1e^4t + 2.1e^(-6t)
