Answer:

x = 48

Step-by-step explanation:

The sum of the angles of a triangle is 180

60+72+x = 180

132+x = 180

x = 180-132

x =48

Given the force field F, find the work required to move an object on the given oriented curve. F = (y, - x) on the path consisti

timofeeve [1]

Answer:

Step-by-step explanation:

We want to compute the curve integral (or line integral)

$\bf \int_{C}F$

where the force field F is defined by

F(x,y) = (y, -x)

and C is the path consisting of the line segment from (1, 5) to (0, 0) followed by the line segment from (0, 0) to (0, 9).

We can write

C = $\bf C_1+C_2$

where

$\bf C_1$ = line segment from (1, 5) to (0, 0)

$\bf C_2$ = line segment from (0, 0) to (0, 9)

so,

$\bf \int_{C}F=\int_{C_1}F+\int_{C_2}F$

Given 2 points P, Q in the plane, we can parameterize the line segment joining P and Q with

Hence $\bf C_1$ can be parameterized as

$\bf r_1(t) = (1-t, 5-5t)$ for 0 ≤ t ≤ 1

and $\bf C_2$ can be parameterized as

$\bf r_2(t) = (0, 9t)$ for 0 ≤ t ≤ 1

The derivatives are

$\bf r_1'(t) = (-1, -5)$

$\bf r_2'(t) = (0, 9)$

and

$\bf \int_{C_1}F=\int_{0}^{1}F(r_1(t))\circ r_1'(t)dt=\int_{0}^{1}(5-5t,t-1)\circ (-1,-5)dt=0$

$\bf \int_{C_2}F=\int_{0}^{1}F(r_2(t))\circ r_2'(t)dt=\int_{0}^{1}(9t,0)\circ (0,-9)dt=0$

In consequence,

$\bf \int_{C}F=0$

Due: Today Raven told Micah the perimeter of the swimming pool was 35 feet, the dimension of the pool were 5 ft by 7 ft. Micah s

pychu [463]

Answer: Micah

Step-by-step explanation:

Given

Raven told Perimeter of the swimming pool is $35\ ft$

Micah said Perimeter is $24\ ft$

The actual dimension of the swimming pool is $5\ ft\times 7\ ft$

Perimeter is given by $2(l+w)$

Using this, the perimeter is

$\Rightarrow P=2(5+7)\\\Rightarrow P=2\times 12=24\ ft$

$\therefore$ Micah statement is correct.

Tyrell says if you subtract 1 from a number you get an even number.he writes these two equations as examples. 3-1=2 11-1=10

Anna11 [10]

Answer:

No Tyrell is incorrect.

Step-by-step explanation:

Tyrell is incorrect because if you take any even number and subtract one from it you would get an odd number. For example take 20, if you do 20-1 then that would give you 19.
