Answer:
About 53.13 degrees.
Step-by-step explanation:
If we draw the path of the hiker, or rather, all three vectors with vector B having its starting point at the end point of vector A, a right triangle is formed. We will most likely be using trigonometric functions to solve this.
vector A is parallel to the x axis (West - East), and vector B is perpendicular, so we'll be using the inverse tangent function to get the angle based on the ratio of the lengths of vector B to vector A, which is 
atan
degrees.
If one would be pedantic, they'd say that the direction we have to go to get from vector C to vector A is clockwise, which is anti-mathematical, the true answer would be -53.13 degrees. Alternatively, whatever 360-53.13 is.
Answer:
Yes and SSS
Step-by-step explanation:
Let’s write down the ratios to figure out the first question:
RP:MN=5:3
NP:ML=10:6
RN:LN=15:9
Notice that we can simplify all of those ratios to 5:3. That means that the sides are all similar, so yes, the triangles are similar.
For the second question: They are similar by because all sides are similar in the same ratio. That means that they are similar by the SSS similarity.
Hope that helps
Answer:
4
+x
Step-by-step explanation:
That is the correct answer if you want to multiply x by 4x+1
x(4x+1)
(x · 4x) + (x·1) By using the distributrive property
(4) + (x)
= 4 + x
I hope this helps :)
Good luck!
Answer:
c. 8.25
Step-by-step explanation:
The given scenario corresponds to binomial experiment because
1. There are two possible outcomes i.e. each number can be working or not working.
2. On each dialing the probability of getting working cell number is p=0.55.
3. Cell phone numbers are randomly dialed so these are independent.
4. A pollster dialed 15 cell numbers i.e. n=15.
The mean number of calls that reach a working cell number can be calculated by computing mean of binomial distribution using the given information.
Mean of binomial distribution=E(x)=np
The mean number of calls that reach a working cell number=15*0.55=8.25
Thus, the mean number of calls that reach a working cell number=8.25
