Meters are 100 times as large as centimeters. So, if we have 800 centimeters, that is the equivalent of 8 meters.
In this scenario, we want to know how many meters is equivalent to 7
centimeters. Since 1 centimeter is 1/100 of 1 meter, we can multiply the
amount of centimeters by 1/100 to get the measurement in meters.
7(1/100) will yield 7/100 or .07 meters.
To write this in scientific notation, we take 7 and multiply it by 1/100 or 10^(-2). This is written "7x10^(-2) m".
7 centimeters in scientific notation is just 7x10^0 because it is a
single unit. Scientific notation allows us to compare the size of
numbers more easily.
For instance 7.12x10^3 is much larger
than 7.12x10^(-3) due to the exponents and how many "10s" we are
mulitplying our number by.
Ok, a fun hack
if f⁻¹(a)=b then f(b)=a
so if f⁻¹(7)=b then f(b)=7
to find b, find x such that f(x)=7
7=0.5(3)^x
times both sides by 2 (or divide both sides by 0.5)
14=3^x
take log₃ of both sides
Answer:
Step-by-step explanation:
Put the values of x and y in the equations and solve the resulting system.
A(2) +(-3) = 5
A(2) +B(-3) = 20
__
The first equation tells the value of A:
2A = 8 . . . . add 3
A = 4 . . . . . .divide by 2
This and the second equation tells the value of B:
(4)(2) -3B = 20
-3B = 12 . . . . . subtract 8
B = -4 . . . . . . . divide by -3
The values of A and B are 4 and -4, respectively.
Answer:
x=-8
Step-by-step explanation:
16x+35 = -93
subtract 35 from each side
16x = -93 -35
16x = -128
divide each side by 16
x = -128/16
x=-8
Answer:
The second term is 3
Step-by-step explanation:
C(n)=-6(-1/3) n-1
The first term of the sequence
C(1) = -6(-1/3)1-1
C(1) = (2)-1
C(1) = 1
C(n)=-6(-1/3) n-1
The second term of the sequence
C(2) = -6(-1/3)2-1
C(2) = -6(-2/3)-1
C(2) = 4-1
C(2) = 3
