What is the slope of the tangent line through (3,2) and (x,y) for x=-2 and y=x3

1 answer:

3 0

First you must derive the equation to find the slope:
y = x ^ 3
y '= 3x ^ 2
Then, for x = -2 we have the slope is:
y '(- 2) = 3 (-2) ^ 2 = 12
Then the equation of the line with slope equal to 12 and passing through point (3,2) is:
y = 12 (x-3) +2

What 1,045 to the nearest thousands

1,045 to the nearest thousands would be 1,000 because you must round down since there are no numbers close enough to round up.

svetlana [45]

Answer:

Starting from the left, top to bottom. first answer is 8, second is 21.3, third is 64, 204.8. Right side is essentially y=x to a power, the answers are from top to bottom, 8,27,64,125

Step-by-step explanation:

Essentially, its just asking you to divide the given y values by the x values.

Solve the equation 3x-4=8-x

solmaris [256]

Answer:

x=3

Step-by-step explanation:

3x-4=8-x(Group like terms)

3x+x=8+4(Add both sides)

4x=12(After adding you will proceed to divide both sides by 4)

x=3(x is 3 because 4 can divide 12 3 times that's why we have x as equal to 3)

x = 13

Arc RQ = 180°

Step-by-step explanation:

PEQ is an inscribed angle and the measure of an inscribed angle in a circle is equal to half of the arc it sees.

The perimeter of a circle is always 360° therefore

2 × (5x + 15) + 9x + 17 + 6x - 12 = 25x + 35 = 360°

25x = 360 - 35

25x = 325

x = 13

Since arc RQ is equal to 10x + 30 we replace x with the value we just got

10×13 + 30 = 160°

Need hep teaching my daughter. Janet went to Resturant and left 20% tip. If tip was $3.20 how much was meal? Solve with equation

Stels [109]

Answer:

The meal was $16.00.

Step-by-step explanation:

since the equation for finding the tip is: decimal of percent times total bill, what you want to do is isolate the bill. you do this by dividing both sides by percent and your equation is total cost = tip/percent

let's say our total equation is x.

x=3.20/0.2

x=16

Now check your work.
