Answer:

x=\frac{5(+/-)\sqrt{25-8a}} {2a}

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

ax^{2} -5x+2=0

so

a=a\\b=-5\\c=2

substitute in the formula

x=\frac{5(+/-)\sqrt{-5^{2}-4(a)(2)}}{2a}

x=\frac{5(+/-)\sqrt{25-8a}} {2a}

Find the x- and y-intercepts of the function f(x) = log(2x + 1) − 1.
sleet_krkn [62]
<span>Alright, here's your answer.

y-intercept is computed (not found) by assigning x = 0 and computing y: here that is f(0) = Log(2*0 + 1) – 1 = Log(1) – 1 = 0 – 1 = -1 
y-intercept is (0, -1) 

x-intercept is computed by solving f(x) = 0 for x: here that is 
0 = Log(2x + 1) – 1 → 1 = Log(2x + 1) 

Assuming the Log cited is base 10, then 10^1 = 10^Log(2x + 1) = 2x + 1 

That’s 10 = 2x + 1 

Therefore 9 = 2x 
x = 9/2 = 4.5 
Check this result in the original equation, I did! 

Your answer is - x-intercept is (4.5, 0)

I hope I helped! :)

swat32

The information given about the probability shows that the cardinality of D is 18.

<h3>How to calculate the probability?</h3>

From the complete information, the number of red-colored cards is 26.

Also, the number of red-colored number cards will be 18.

The cardinality of a set is a measure of a set's size, meaning the number of elements in the set.

Here, the cardinality of set D is 18.

Here is the complete question:

Take a deck of playing cards. Form following sets out of those:

A = Set of Face Cards

B = Set of Red Coloured Face cards

C = Set of Black Coloured Face Cards

D = Set of Red Coloured Number Cards
