The speed of sound (shockwave) in an explosion is 100mph. How many seconds does the shockwave reach 2km away?​

Mathematics

4 0

Answer:

t = 44.73 s

Step-by-step explanation:

Given that,

The speed of a sound wave, v = 100 mph = 44.704 m/s

We need to find the time taken by the shockwave to reach 2 km i.e. 2000 m

We know that,

Speed = distance/time

So,

t=\dfrac{d}{v}\\\\t=\dfrac{2000}{44.704}\\\\t=44.73\ s

So, it will take 44.73 seconds to reach 2 km.

the graph of f(x) is shown below. what are the values of a, b, c, and d in the definition of f(x) below? (graph and definition o
Otrada [13]

Answer:

Step-by-step explanation:

For the given piecewise function,

Let the equation of the segment AB is,

y = ax + 7 where x < -2

Since a point (-2, 3) lies on the given line,

3 = a(-2) + 7

3 - 7 = -2a

a = 2

Therefore, f(x) = 2x + 7 when x < -2

For the segment BC,

f(x) = 3 where -2 ≤ x ≤ 2

For the segment CD,

f(x) = bx + 9

Since a point (2, 3) lies on this segment,

f(2) = 2b + 9 = 3

2b = 3 - 9

b = -3

Therefore, equation of segment CD will be,

f(x) = (-3)x + 9   where x > 2

Miki has 104 nickels and 88 dimes. She wants to divide her coins into groups where each group has the same number of nickels and
Cerrena [4.2K]

Answer:

8

Step-by-step explanation:

To find the largest number of groups she can have, find the largest number that can divide 104 and 88 evenly.

This number is 8, since 8 divides 104 to 13 and it divides 88 to 11.

This means each group will have 13 nickels and 11 dimes.

So, the answer is 8 groups.
