Which point is the image of P​

Mathematics
1 answer:

3 0

Answer:

A

Step-by-step explanation:

we know that xoy is 90° on every quadrant

also the origine where p start is a little bit down from x axis so A is the right answer as it is the most logical point

D and C cant be P because are a very large angle of rotation than 105.B is smaller then 105 rotation of p so A is the right one.

Find the exact length of the curve. y2 = 4(x + 1)3, 0 ≤ x ≤ 1, y > 0
mylen [45]
We can find this using the formula: L= ∫√1+ (y')² dx

First we want to solve for y by taking the 1/2 power of both sides:

y=(4(x+1)³)^1/2
y=2(x+1)^3/2

Now, we can take the derivative using the chain rule:

y'=3(x+1)^1/2

We can then square this, so it can be plugged directly into the formula:

(y')²=(3√x+1)²
<span>(y')²=9(x+1)
</span>(y')²=9x+9

We can then plug this into the formula:

L= ∫√1+9x+9 dx *I can't type in the bounds directly on the integral, but the upper bound is 1 and the lower bound is 0
L= ∫(9x+10)^1/2 dx *use u-substitution to solve
L= ∫u^1/2 (du/9)
L= 1/9 ∫u^1/2 du
L= 1/9[(2/3)u^3/2]
L= 2/27 [(9x+10)^3/2] *upper bound is 1 and lower bound is 0
L= 2/27 [19^3/2-10^3/2]
L= 2/27 [√6859 - √1000]
L=3.792318765

The length of the curve is 2/27 [√6859 - √1000] or <span>3.792318765 </span>units.

On a number line the directed line segment from Q to S has endpoints Q at -14 and S at 2. Point R partitions the directed line s
liq [111]

Answer:

Step-by-step explanation:

The distance from Q to S is 2 - (-14), or 16.

We start at point Q.  Note how 3 and 5 add  up to 8, which allows us to write:

R = Q + (3/8)(16), or R = -14 + 6, or R = -8.

From R to S it is (5/8)(16), or 10 units.

The directed line segment is partitioned into segments of lengths 6 and 10, whose combined length is 16, as expected.

At what point do the lines y=x-4 and 2x+y=2 intersect?
earnstyle [38]

Answer:

  • (2, -2)

Step-by-step explanation:

<u>Given</u>

  • y = x - 4
  • 2x + y = 2

<u>Solving by substitution</u>

  • 2x + (x - 4) = 2
  • 3x - 4 = 2
  • 3x = 6
  • x = 2

<u>Then finding y</u>

  • y = x - 4
  • y = 2 - 4
  • y = -2

Intersection point is (2, -2)
