Answer:
2.85-6.2÷2^2= 1.3
Step-by-step explanation:
You have to follow PEMDAS.
P- parentheses ()
E- exponents ^x
M- multiplication ×
D- division ÷
A- addition +
S- subtraction -
(if it is not in the equation skip it and do the next step)
Exponents first.
2^2 is 4.
Equation looks like this
2.85-6.2÷4
Now division.
6.2÷4 is 1.55
Equation looks like this
2.85-1.55
Now subtraction.
2.85-1.55 is 1.3
You answer is 1.3
Hope this helped/helps you!!! :)
Answer:
The correct option is;
d(t) = 6·cos(π/3·t) + 28
Step-by-step explanation:
The general form of a cosine function is given as follows;
y = A·cos(B·x - C) + D
Where;
A = The amplitude = The distance from the peak to the midline = 1/2×(Maximum - minimum)
The amplitude = 1/2 × (34 - 22) = 6 inches
B = 2·π/P = 2·π/6 = π/3
P = The period = 6 seconds
C/B = The phase shift
D = The midline = Minimum + Amplitude = 22 + 6 = 28 inches
x = The independent variable
Therefore, to model the function of the wave can be given as follows;
d(t) = 6·cos(π/3·t) + 28
Answer:
Parallel
Step-by-step explanation:
The slopes are the same, they are both 0.
Answer:
3
Step-by-step explanation:
I can help you set up the equation, if you don't actually practice isolating you're never gonna learn,
it says the /sum of a number and seven/ which means n+7
is equal to /five less than the number/ so n-5
so your two parts are
n+7 = n-5
