if 8^y = 16^x + 2 what is the value of Y
Answers
Answer:
y= -8
Step-by-step explanation:
8^y = 16^(y+2)
//to solve make the base equal, both 8 and 16 are powers of (2
(2^3)^y = (2^4)^(y+2)
//simplify, remember when doing this multiply the powers
2^3y = 2^(4y+8)
// now we can just make the 2 powers equal
3y = 4y+8
0=y+8
y= -8
check:
8^(-8) = 16^(-6)
2^(-24) = 2^(-24)

X = 3.
Step-by-step explanation:
1) Subtract 6 from both sides.
[tex]3x = 15 - 6[/tex]
2) Simplify 15 - 6 to 9.
[tex]3x = 9[/tex]
3) Divide both sides by 3.
[tex]x = \frac{9}{3} [/tex]
4) Simplify 9/3 to 3.
[tex]x = 3[/tex]

The first round of a racquetball tournament begins with 148 players. Every round, half of the players lose and are eliminated from the tournament leaving 74 players in the second round. The tournament continues in the same fashion until one player finally wins the tournament. Determine if the scenario describes an arithmetic or a geometric sequence then write the formula for the sequence described.
Answers
Answer:
Notice that 99 players need to be eliminated for there to be declared a winner. Notice also that every match eliminates exactly one person. Therefore, 99 matches are needed to eliminate 99 people and therefore declare a winner. The rest of the information is irrelevant. Therefore, the total number of matches is text divisible by 11.

A sample of 600 g of radioactive lead-210 decays to polonium-210 according to the function A(t) = 600e ^-0.032t, where t is time in years. Find the amount of radioactive lead remaining after
(a) 3 yr
(b) 8 yr
(c) 15 yr
(d) find the half-tie
round to the nearest integer as needed.
Answers
The amount of radioactive lead remaining after 3 years is 545gm.
The amount of radioactive lead remaining after 8 years is 464gm.
The amount of radioactive lead remaining after 15 years is 371gm.
The half-tie for radio active lead is 21.66 years.
Given that,
A sample of 600 g of radioactive lead-210 decays to polonium-210,
According to the function A(t) = 600e ^-0.032t,
Where, t is time in years.
We have to find,
Find the amount of radioactive lead remaining after.
According to the question,
Function [tex]A(t) = 600e^{(-0.032t)}[/tex]
After 3 years the amount of radioactive lead,[tex]A(3) = 600\times e^{(-0.032t)} \\\\A (3) = 600 \times \dfrac{1}{e^{0.032\times 3} } \\\\e^{0.096} = 1.10075\\\\A (3) = 600 \times \dfrac{1}{e^{0.096} } \\\\A (3) = 600 \times \dfrac{1}{1.10075} } \\\\A(3) = \dfrac{600}{1.10075}\\\\A(3) = 545gm[/tex]
The amount of radioactive lead remaining after 3 years is 545gm.
After 8 years the amount of radioactive lead,[tex]A(8) = 600\times e^{(-0.032t)} \\\\A (8) = 600 \times \dfrac{1}{e^{0.032\times 8} } \\\\e^{0.0256} = 1.129175\\\\A (8) = 600 \times \dfrac{1}{e^{0.0256} } \\\\A (8) = 600 \times \dfrac{1}{1.129175} } \\\\A(8) = \dfrac{600}{1.129175}\\\\A(8) = 464gm[/tex]
The amount of radioactive lead remaining after 8 years is 464gm.
After 15 years the amount of radioactive lead,
[tex]A(15) = 600\times e^{(-0.032t)} \\\\A (15) = 600 \times \dfrac{1}{e^{0.032\times 15} } \\\\e^{0.48} = 1.61607\\\\A (8) = 600 \times \dfrac{1}{e^{0.48} } \\\\A (8) = 600 \times \dfrac{1}{1.61607} } \\\\A(8) = \dfrac{600}{1.61607}\\\\A(8) = 371gm[/tex]
The amount of radioactive lead remaining after 15 years is 371gm.
The half-tie for radioactive lead,[tex]A(15) = 600\times \dfrac{1}{2} = 600e^{-0.032t} \\\\= e^{(-0.032t)} = \dfrac{1}{2}\\\\Taking \ log \ on \ both \ sides\\\\= -0.032t = ln2\\\\= t = \dfrac{ln2}{-0.032}\\\\= t = 21.660\\\\= t = 21.66 years[/tex]
The half-tie for radio active lead is 21.66 years.

A random sample of n = 16 scores is obtained from a parent population with σ = 12. If the sample mean is 6 points greater than the population mean, what is the z-score for the sample mean?
Answers
Answer:
0.5
Step-by-step explanation:
Sample mean, x = 6 points greater than population mean ;
Population mean, m = 16
Standard deviation, s = 12
Zscore = (sample mean - population mean) / standard deviation
Zscore = (x - m) / s
x = 16 + 6 = 22
Zscore = (22 - 16) / 12
Zscore = 6 /12
Zscore = 0.5

help AB and CD are straight lines find z
Answers
Answer: z=16
Step-by-step explanation:
Angles on a straight line add up to 180.
As AB is a straight line we can use that to help us find z.
So you would do 68+85+11=164 (I got the 11 from the angle trapped between like C and F as opposite angles are the same).
Then you would do 180-164=16
So z=16

Step-by-step explanation:
Answer:
If the flea is to the left of zero and its absolute value is 3.6, it means that the flea is located at a negative value on the number line. Since the absolute value of its location is 3.6, we can deduce that the flea is located at -3.6 on the number line.
