Write a quadratic equation with roots of 3/4 and -4

Vaselesa [24]

A quadratic equation given roots is solved by using the relation

${x}^{2} - (sum \: of \: roots)x + product \: of \: roots$

from the question,

sum of the root will be

$\frac{3}{4} + ( - 4) = \frac{3}{4} - 4$

$= \frac{3 - 16}{4}$

$= \frac{ - 13}{4}$

and also, product of the roots will

be

$\frac{3}{4} \times ( - 4) = - 3$

now substituting the sum of roots and product of roots into the equation

${x}^{2} - ( - \frac{13}{4} )x - 3$

$= {x}^{2} + \frac{13}{4} x - 3$

as the quadratic equation for the root 3/4 and -4

Two cards are drawn without replacement from a standard deck of 52 cards. What is the probability that one of the cards is red a

alukav5142 [94]

Total cards = 52
Total red cards = 26
Total black cards = 26

P(one red and one black) = P(red and then black)+ P(black and then red)
P(one red and one black) =(26/52)(26/51) + (26/52)(26/51)
P(one red and one black) = 26/51 (Answer A)

ladessa [460]

Answer:

Pedro spent 9 weeks with his uncle and his friend.

Step-by-step explanation:

First, you need to find the amount of weeks Pedro spent with his friend. The statement indicates that he spent two weeks more with his friend than with his uncle which means that you have to add the number of weeks he spent with his uncle plus 2, which you can show in a number line:

$3\frac{1}{2}$ 2
