If you would like to know what is your average speed, you can calculate this using the following steps:

1 3/4 miles = 7/4 miles ...half an hour
7/4 miles * 2 = 7/2 miles = 3 1/2 miles ... one hour

Result: Your average speed is 3 1/2 miles per hour.

Two construction workers, Tyrone and Diego, are standing 15 yards apart, looking up at a piano hanging between the two men from

Yanka [14]

Answer:

The distance between Tyrone and the piano is 23.7 yards

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of angle P

Remember that the sum of the internal angles of a triangle must be equal to 180 degrees

∠T+∠D+∠P=180°

substitute the given values

65°+77°+∠P=180°

142°+∠P=180°

∠P=180°-142°=38°

step 2

applying the law of sines

$\frac{TD}{sin(P)}=\frac{TP}{sin(D)}$

substitute the given values

$\frac{15}{sin(38\°)}=\frac{TP}{sin(77\°)}$

$TP=\frac{15}{sin(38\°)}(sin(77\°))\\\\TP=23.7\ yd$

therefore

The distance between Tyrone and the piano is 23.7 yards

1 point) Use Stoke's Theorem to evaluate ∫CF⋅dr∫CF⋅dr where F(x,y,z)=xi+yj+1(x2+y2)kF(x,y,z)=xi+yj+1(x2+y2)k and CC is the bound

Drupady [299]

Answer:

Step-by-step explanation:

Thinking process:

$\int\limits^a_b {cF} \, .dr$

= $\int\limits^a_b {x} \, dx \int\limits^a_b {x} \, dx curlFdS$ by Stoke's Theorem

= $\int\limits^a_b {} \, \int\limits^a_b {} \, < 12y, -12x, 0 > .< z_x,-z_y, 1 > dA\\= \int\limits^a_b {} \, \int\limits^a_b {} \, < 12y, -12x, 0 > .< 2x, 2y, 1 > dA$ since z = $25-x^{2} -y^{2} \\= 0$
