Answer:
x=1
y=s
z=1
Step-by-step explanation:
(x, y, z)=(1, 0, 1)
Substitute 0 for y
Confirming if t=0 satisfy the other equation
x = e^−2t cos 4t = e^−2(0)cos(4*0)
= e^(0)cos(0) = 1
z = e^−2t = e^−2(0) = 0
Therefore t=0 satisfies the other equation
Finding the tangent vector at t=0
The vector equation of the tangent line is
(1, 0, 1) +s(0,1,0)= (1, s, 1)
The parametric equations are:
x=1
y=s
z=1
Step-by-step explanation:
You substitute the given values into the formula
E = (1+0.12)^ 15-1 / 15
Put this one your calculator and round the answer to 2 d.p.
The answer is 468............
Answer:
1. n(4.75+30+2.50)
2. 4.75n+30n+2.50n
Step-by-step explanation:
n is the number of shirts they buy. It says that each shirt costs $4.75, and for each shirt they add an extra $30 and $2.50 for the setup fee and to peint each shirt. The word each shows that you have to times. You have to times n by each number or to make it shorter put all three numbers in parenthesis put the n ouside of the parenthesis.
Hope that helps.
In order
1) given
2) multiplication property of equality
3) distribution property of equality
4) addition or subtraction property of equality
5) subtraction property
In the second one, they are multiplying both sides to get rid of the fraction
In the third one, they are showing the equation after distributing 2 through the parenthesis
In the fifth one, they are subtracting 4x from both sides to get x = 2
I hope this helps!
