R'S' is equal in length to RS.
length doesnt change, it was just rotated.
Answer:
-(x + 5)(3x + 1)
Step-by-step explanation:
Step 1: Factor out negative
-1(3x² + 16x + 5)
Step 2: Factor quadratic
-(x + 5)(3x + 1)
Answer:
Both are rational.
Step-by-step explanation:
As a rational number can be written in the form p/q where p,q are co-prime integers, let a=p1/q1 b=p2/q2.
And we know the product of two integers is an integer
p1q2, p2q1 are integers. And the sum or difference of two integers is rational, rather being specific, it is an integer.
Thus a+b and a-b is rational.
Answer:
C. 6,000 km
Step-by-step explanation:
v = speed at S-wave travel through the earth = 8 km/sec
t = time of travel for the S-wave through the earth = 13 minutes = 13 x 60 seconds = 780 seconds (Since 1 minute = 60 seconds)
d = distance traveled by S-wave in the given time interval
Distance traveled by S-wave in the given time interval is given as
d = v t
inserting the above values in the formula
d = (8 km/sec) (780 sec)
d = 6240 km
the closest choice is 6000 km at option C
So Option C
Answer:
The correct option is;
The function will intersect at x = -2 and x = 1
Step-by-step explanation:
The question parameters are
The functions in the question are f(x) and g(x)
The solution to the equation f(x) = g(x) are -2, and 1
Given that the equations, f(x) and g(x), are both given in values of x, their solution will be the x values that satisfies both functions
Therefore, the functions will intersect (have the same values of f(x) and g(x)) at the points of the solutions, which are given as x = -2, and x = 1
