HELP PLEASE WILL GIVE BRAINIEST ANSWER!!

1 answer:

7 0

Sorry but I can only help with the first 2.
1. Wherever you see 'a' just replace it with 2 and wherever you see 'b' just replace it with 5. That will give us $(2*2)^{(5-1)}=4^4=4*4*4*4=256$
2. Doing the same thing as what you did in question 1, you will have
$(7*3)^{(-2)}=21^{-2}= \frac{1}{21^2}= \frac{1}{441}$
Please mark as brainliest.

Fill in the given values and simplify.

$\dfrac{g(x+h)-g(x)}{h}=\dfrac{\dfrac{1}{x+h}-\dfrac{1}{x}}{h}\\\\=\dfrac{x-(x+h)}{h\cdot x(x+h)}\\\\=\dfrac{-1}{x(x+h)}$

Determine whether the value is from a discrete or continuous data set. Number of coins in a jar is 78 number of coins in a jar i

Phoenix [80]

Determine whether the value is from a discrete or continuous data set. Number of coins in a jar is 78 number of coins in a jar is 78

Answer: Number of coins in a jar is from a discrete data set. Because the given variable is countable in a finite amount of time.

If a variable can take on any value between two specified values, it is called a continuous variable; otherwise, it is called a discrete variable.

A particular circle in the standard (x,y) coordinate

matrenka [14]

For any circle with Cartesian equation
$(x-a)^2 + (y-b)^2 = r^2$ ,
we have that the centre of the circle is $(a,b)$ , and the radius of the circle is $r$ .

So in the case that
$(x-5)^2 + y^2 = 38$ ,
we essentially have that
$a = 5, b = 0, r^2 = 38$ .

So the centre of the circle is $(5,0)$ , and the radius is $\sqrt{38}$ .
