Suppose you need to know an equation of the tangent plane to a surface S at the point P(4, 1, 4). You don't have an equation for
Alex777 [14]

Answer:

15x-8y+9z=88

Step-by-step explanation:

We are given that

Equation of curves

r_1(t)=

r_2(u)=

Both curves lie on S.

We have to find the equation of tangent plane at P(4,1,4).

r'_1(t)=,r'_2(u)=

r_1(0)=, r_2(1)=

Hence, t=0 and u then it satisfied the given point.

Substitute the values in the derivatives

r'_1(0)=,r'_2(1)=

r'_1(0)\times r'_2(1)=\times =

The equation of tangent at point P(4,1,4) is given by

30(x-4)-16(y-1)+18(z-4)=0

30x-120-16y+16+18z-72=0

30x-16y+18z=176

15x-8y+9z=88

7w + 6 + 2w = (w + 2)
Sindrei [870]

Hey there!

The correct answer is w = \frac{-1}{2}

7w + 6 + 2w = w + 2          ~ Write the equation

9w + 6 = w + 2                   ~ Simplify

8w + 6 = 2                          ~ Subtract w from both sides

8w = -4                             ~ Subtract 6 from both sides

w = \frac{-1}{2}                                ~ Divide both sides by 8

Hope it helps and have a great day!

Suppose that the local sales tax rate is 6.25% and you purchased a used car for $16,800. What is the car’s total cost?
Tanzania [10]
Total= Car Cost + (Car Cost * Tax %)

Total= $16,800 + ($16,800 * 6.25%)
convert % to decimal form; divide % by 100

Total= $16,800 + ($16,800 * 0.0625)
multiply inside parentheses

Total= $16,800 + $1,050

Total= $17,850


ANSWER: The total cost for the used car with tax is $17,850.

Hopd this helps! :)
