Answer:
Hundreds
Step-by-step explanation:
Refer to the underlined numbers:
3427<u>7</u> - 7 is in the ones place
342<u>7</u>7 - The second 7 is in the tens place
34<u>2</u>77 - 2 is in the hundreds place
3<u>4</u>277 - 4 is in the thousands place
<u>3</u>4277 - 3 is in the ten thousands place
Bx + Cy = D
Solve for y . . .
*subtract Bx from both sides
Bx - Bx + Cy = D - Bx
Cy = D - Bx
*now divide both sides by C
Cy/C = (D - Bx)/C
Cy/C = D/C - Bx/C
y = D/C - (B/C)x
<u><em>y = -(B/C)x + D/C</em></u>
25/3 ft/s is speed of the tip of his shadow moving when a man is 40 ft from the pole given that a street light is mounted at the top of a 15-ft-tall pole and the man is 6 ft tall who is walking away from the pole with a speed of 5 ft/s along a straight path. This can be obtained by considering this as a right angled triangle.
<h3>How fast is the tip of his shadow moving?</h3>
Let x be the length between man and the pole, y be the distance between the tip of the shadow and the pole.
Then y - x will be the length between the man and the tip of the shadow.
Since two triangles are similar, we can write
⇒15(y-x) = 6y
15 y - 15 x = 6y
9y = 15x
y = 15/9 x
y = 5/3 x
Differentiate both sides
dy/dt = 5/3 dx/dt
dy/dt is the speed of the tip of the shadow, dx/dt is the speed of the man.
Given that dx/dt = 5 ft/s
Thus dy/dt = (5/3)×5 ft/s
dy/dt = 25/3 ft/s
Hence 25/3 ft/s is speed of the tip of his shadow moving when a man is 40 ft from the pole given that a street light is mounted at the top of a 15-ft-tall pole and the man is 6 ft tall who is walking away from the pole with a speed of 5 ft/s along a straight path.
