Answer:

5√2 is as simple as it gets

5√2 ≈ 7.071068

Step-by-step explanation:

One simplifies radical expressions by removing from under the radical any squares that might be there. 2 is a prime number, so has no square factors. The simplest form of this radical expression is the one given:

5√2

Your calculator can tell you the value of this irrational number is about ...

PLEASE HELP it should be easy for someone but I can’t do it

-Dominant- [34]

Answer:

Total crackers on the plate are 12

Step-by-step explanation:

Manuel ate crackers = $\frac{1}{3}$

His brother ate crackers = $\frac{1}{4}$

Crackers left on the plate = 5

We need to find how many crackers were there on the plate.

Let x be the total crackers on the plate

So, we can write the equation

$x-\frac{1}{3}x-\frac{1}{4}x=5$

Because 1/3 and 1/4 crackers are eaten and 5 are left so, we subtract 1/3x and 1/4x from x and equal it to 5

$\frac{12x-4x-3x}{12}=5\\\frac{12x-7x}{12}=5\\\frac{5x}{12}=5\\x=\frac{5*12}{5}\\x=12$

So, we get x = 12

Therefore, total crackers on the plate are 12

Solve the exponential equation for x. 625 = 5 (7x-3)

posledela

Answer:

<h2>A. x = 1</h2>

Step-by-step explanation:

$5^{7x-3}=625\\\\5^{7x-3}=5^4\iff7x-3=4\qquad\text{add 3 to both sides}\\\\7x=7\qquad\text{divide both sides by 7}\\\\x=1$

Find the inverse function of <br><img src="https://tex.z-dn.net/?f=f%28x%29%20%3D%209%20%2B%20%20%5Csqrt%7B4x%20-%204%7D%20" id=

Vedmedyk [2.9K]

Answer:

$\displaystyle {f}^{ - 1}(x) = \frac{1}{4} (x - 18x + 85)$

Step-by-step explanation:

we would like to find the inverse of the following function:

$\displaystyle f(x) = 9 + \sqrt{4x - 4}$

to do so substitute y for f(x):

$\displaystyle y= 9 + \sqrt{4x - 4}$

interchange variables:

$\displaystyle x= 9 + \sqrt{4y - 4}$

cancel 9 from both sides:

$\displaystyle \sqrt{4y - 4} = x - 9$

square both sides:

$\displaystyle 4y - 4= x - 18x + 81$

add 4 in both sides:

$\displaystyle 4y = x - 18x + 85$

divide both sides by 4:

$\displaystyle y = \frac{1}{4} (x - 18x + 85)$

substitute back:

$\displaystyle {f}^{ - 1}(x) = \frac{1}{4} (x - 18x + 85)$

and we're done!
