Answer:
x = 8 and y=9 or y = 8 and x = 9
Step-by-step explanation:
8 x 9 = 72
8+9 = 17
9 x 8 = 72
9+8 = 17
Answer:
The average rate of change in that interval is 1.99
Step-by-step explanation:
Here we have that the difference quotient for g(x) is:
Remember that for a general function f(x), the difference quotient is:
So if we look at the difference quotient for g(x), we can conclude that:
Also remember that the average rate of change in an interval (a, b) is just:
So here we want the average rate of change of g(x) in the interval from x = -2 to x = 1, this is:
The average rate of change in that interval is 1.99
Answer:
True
Step-by-step explanation:
We actually can use Sine, Cos, or Tangent to solve for the angles, which would give the angle, but graphing it came up with an Obtuse Scalene triangle.
Answer:
In this maths tutorial, we introduce exponents / powers and roots using formulas, solved examples and practice questions.
Powers and Roots | Formulas, Solved Examples, Practice Problems
Exponents, also called powers, are a way of expressing a number multiplied by itself by a certain number of times.
When we write a number a, it is actually a1, said as a to the power 1.
a2 = a*a
a3 = a*a*a
:
:
an = a*a*a*a* . . . n times.
Basic formulas in Powers and Roots
Some basic formulas used to solve questions on exponents are:
(am)n = (an)m = amn
am.an = am+n
a-m = 1/am
am/an = am-n = 1/an-m
(ab)n = anbn
(a/b)n = an/bn
a0 = 1
