This is a SOH-CAH-TOA problem, or trigonometry! Take a look at the attached image for a sketch of this problem.
(a) To find the distance up the wall, we'll need to use the sine function. This is because we know the angle is opposite the wall and we also know the hypotenuse.
sin(58.5) = x/4
x = (4)(sin(58.5)) ---> Plug this into your calculator to get the answer! And make sure your calculator is in degrees if that is an option.
x = 3.4 meters
(b) To find the distance between the foot of the ladder and the wall, we'll need to use the cosine function. This is because we know the angle is adjacent to the wall and we also know the hypotenuse.
cos(58.5) = x/4
x = (4)(cos(58.5))
x = 2.1 meters
Hope this helps!! :)
Hi there
Amount financed
21349-3000=18349
Total paid
5years=60months (12×5)352×60 =21,120
Total interest
21,120−18,349=2,771
APR is(2,771×2×12)÷(18,349×61)=0.059×100=5.9%...answer
Hope it helps!
Divide 33 by three because there are 3 feet in a yard
There are 11
Answer:
y=2.5x
Step-by-step explanation:
To get the equation in y = mx + b format, we need to find m and b, the slope and y-intercept.
To find the slope, we need two points on a graph, which we have.
First, the slope
The formula for slope is
Our points, (6, 15) and (2, 5)
Plugging into our equation:
, which is 10 divided by 4, which is 2.5
Our equation now:
To find our b, we need to plug in one x value.
(6, 15) are our pair of points.
6 = x
15 = y
=>
=>
If b is 0, then we don't need to include b.
Our equation is
