Answer:

Your heart rate is 1.1 beats per second. Your friend's heart rate is 1.2 beats per second. Yes, the rates have the same rate (bps).

Step-by-step explanation:

Your heartbeat = 22:20 (can  be reduced to 11:10) or 22/20 = 1.1 bps

Friend's heartbeat = 18:15 (can be reduced to 6:5) or 18/15= 1.2 bps

Which of the following expressions is equivalent to the radical expression?
qwelly [4]
The correct answer is B) m^{2/3}n^{5/3}. 

The denominator of the exponent is the root we are taking.  The numerator is the exponent of the radicand.  This means 3 will be the denominator, since it is a cubed root, and 2 will be the numerator of m while 5 will be the numerator of n.

The points (-18,15) and (-20,15) lie on a circle with a radius of 1. Find the coordinates of the center of the circle.
FromTheMoon [43]
.hello :
an equation of the circle <span>Center at the w(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : r = 1
</span><span>The points (-18,15) and (-20,15) lie on a circle with a radius of 1:
</span>(-18-a)²+(15-b)² = 1 ....(1)
(-20-a)² +(15-b)² = 1 ....(2)
solve this system :
(1) -(2) : (-18-a)² - (-20-a)² =0
(-18-a)² =(-20-a)² =0
( -18-a = -20-a) or (-18-a = - (-20-a))
1 )  ( -18-a = -20-a) no solution confused : -18=-20
2 ) -18-a =20+a
      -2a =38
      a = -19 
subst in (1) :(-18+19)²+(15-b)² =1
(15-b)² = 0.... 15-b = 0     .... b = 15
the center is :w(-19,15)

1. Input
wel

Answer:

The equilibrium point represents the raising or lowering the price in response to changes in the supply or demand.

If the price of a good is above equilibrium, this means that the quantity of the good supplied exceeds the quantity of the good demanded.

If the quantity is below the equilibrium point, it will create a shortage. because the quantity supplied is less than quantity demanded.

Hope this helps!

Solve the logarithmic equation. Be sure to reject any value of log (X + 8) = log x + log 8​
swat32

Answer:

x = 8/7

Step-by-step explanation:

log (X + 8) = log x + log 8​

We know that log a + log b = log ab

log (X + 8) = log 8x

Raise each side to base 10

10^log (X + 8) = 10^log 8x

x+8 = 8x

Subtract x from each side​

x+8-x = 8x-x

8 = 7x

Divide by 7

8/7 = 7x/7

8/7 =x
