For this chaos we must solve the following equation:

2p ^ 2-1 = 7

Adding 1 to both sides of the equation we have:

2p ^ 2 = 7 + 1\\2p ^ 2 = 8

Dividing by 2 to both sides of the equation:

p ^ 2 = \frac {8} {2}\\p ^ 2 = 4

Applying root to both sides:

p = \pm \sqrt {4}

Thus, we have two solutions:

x_ {1} = + 2\\x_ {2} = - 2

Answer:

x_ {1} = + 2\\x_ {2} = - 2

Answer: p = 2

Step-by-step explanation:

To solve this problem, you first have to add 1 to each side of the equation, leaving you with 2p^2 = 8. Then you divide by 2 on both sides leaving you with p^2 = 4. After that, you take the square root of both sides, and because 4 is a perfect square, you get p = 2 as your final answer.

Consider the graph of the function f(x)=2x.
77julia77 [94]

Given:

The parent function is:

f(x)=2^x

The other function is:

g(x)=2f(x)

To find:

The statement that describes a key feature of function g.

Solution:

We have,

f(x)=2^x

g(x)=2f(x)

Using these two functions, we get

g(x)=2(2)^x

Putting x=0, we get

g(x)=2(2)^{(0)}

g(x)=2(1)

g(x)=2

The y-intercept of the function g at (0,2). So, option A is correct and option B is incorrect.

We know that g(x)\to 0 as x\to -\infty and it will never intersect the line y=0. It means the horizontal asymptote of the function g is

Therefore, the correct option is A.

Can anyone help me please? it’s urgent.
katrin [286]
It said "no association between this dude winning and loss in harsh condition"

now look at harsh condition, total is 20, since there is no association that means they are the same, which is 10 and 10

WIN column total is 168, 158 for normal condition, 10 for harsh condition, adds up to 168.

LOSS column total is 72, 62 for normal condition and 10 for harsh condition, adds up to 72.

if u wana check if it adds up with Normal Condition, 62 plus 158 is 220.

checked, complete, this is david signing off
