A pitcher's arm rotates at a speed of 7 degrees per millisecond (degrees/ms)

2 answers:

8 0

To solve this problem, all we have to do is to use a conversion factor to convert millisecond into seconds. We know that there are 1000 milliseconds in a second, therefore:

pitcher’s arm rotation = 7 degrees / millisecond * (1000 milliseconds / second)

<span>pitcher’s arm rotation = 7,000 degrees / second</span>

If an airplane descends 15 feet every 1.45 seconds, how far would the airplane travel in three and a half minutes? The equation

NemiM [27]

$\qquad\qquad\huge\underline{{\sf Answer}}$

Here we go ~

The air plane descends 15 feels every 1.45 seconds, so it's unit rate is :

$\qquad \sf \dashrightarrow \: \dfrac{15}{1.45} \: \: ft / sec$

Now we have to calculate the descent in 3.5 minutes ~

$\qquad \sf \dashrightarrow \: \dfrac{15}{1.45} \: \: \times 3.5 \times 60$

$\qquad \sf \dashrightarrow \: 2172.41 \: \: ft$

So, the airplane descends 2172.41 feels in three and a half minutes ~

Determine whether or not F is a conservative vector field. If it is, find a function f such that F = ∇f. (If the vector field is

gavmur [86]

$\nabla f=(ye^x+\sin y)\,\vec\imath+(e^x+x\cos y)\,\vec\jmath$

then

$\dfrac{\partial f}{\partial x}=ye^x+\sin y\implies f(x,y)=ye^x+x\sin y+g(y)$

Differentiating with respec to $y$ gives

$\dfrac{\partial f}{\partial y}=e^x+x\cos y=e^x+x\cos y+g'(y)$

$\implies g'(y)=0\implies g(y)=C$

So $F$ is indeed conservative, and

$f(x,y)=ye^x+x\sin y+C$

Attendance at a museum more than tripled from Monday to Saturday. On Monday, 186 people went to the museum. How many people went

ira [324]

Answer:

The number of people who visited museum on Saturday is 558.

Step-by-step explanation:

Number of people went to museum on Monday = 186

Also, the number of people triples on Saturday.

So, Number of people visited on Saturday

= 3 x Number of people who visited museum on Monday

= 3 x 186 = 558

Hence, the number of people who visited on Saturday is 558.
