Answer:
smallest to biggest divide by 100%
Step-by-step explanation:
Function:
f(x) = 2 cos x +1
Note: The values of x should be given in radians.
Therefore;
Substituting for x = 1.5 radians
f(1.5) = 2 Cos 1.5 + 1 ≈ 1.1415
The number of infected people will reach 568 in approximately 4 weeks
<h3>Linear equation and function</h3>
Exponential equations are inverse of logarithmic equation and are represented by the equation below:
y = ab^x
where
a is the base value and x is the exponent
Given the equation that shows the number of infected people from an outbreak of the measles as:
y = 4(6)^t
If the number of infected people reach 568, hence;
568 = 4(6)^t
568/4 = 4(6)^t/4
6^t = 568/4
6^t = 142
Take the natural logarithm of both sides
ln(6^t) = ln142
t = ln142/ln6
t = 4.37
Hence the number of infected people will reach 568 in approximately 4 weeks

Answer:
I simply separated the number into two numbers that I know are directly related to 9. 90 and 45 gives me around 135 ignoring the 22 cents since this is an estimation. 9*10 is equal to 90 and 9 times 5 is equal to 45. So I can estimate that the answer is around 15.
