Answer:
B. 6 < n < 25
Step-by-step explanation:
We are given the triangles WXY and WZY with sides XY and ZY congruent and equal to 8.
As the sides WX = 11 > WZ = 9.
Then, the angles opposite to WX will be greater than the angle opposite to WZ.
i.e. ∠WYX > ∠WYZ
i.e. (7n+5)° > 47°
i.e. 7n° > 42°
i.e. n > °
i.e. n > 6°
Since in ΔWXY, the sum of all three angles is 180°.
This means that (7n+5)° < 180°
i.e. 7n < 175°
i.e. n < °
i.e. n < 25°
Hence, we get that the range of n is 6 < n < 25.
Answer:
Step-by-step explanation:
If we are given the quadratic model, we know that the height of anything on the ground is 0 meters, so that model becomes
I changed your x's to t's since t is for time.
Now we need to factor that quadratic and solve for time:
Since -2 definitely does not equal 0, then
Factor that and find t values of 4 and -2. Again, we know that time will never be negative, so
t = 4 seconds.
Answer:
Of(7) = f(1) + 24
Step-by-step explanation:
Since this Arithmetic Sequence can be written recursively as a function, then we can write the whole sequence, by adding the common difference to the previous function. So writing it as an Arithmetic formula is (placing an example, with a common difference of 4 units):
