Find the zeros of the polynomial p(x) 5-10x

Charra [1.4K]

Answer:

Step-by-step explanation:

The given polynomial is :

p(x) = 5-10x

We need to find the zeros of the above polynomial. To find it, put p(x) = 0

5-10x = 0

Subtract 5 from both sides

5-10x-5=0-5

-10x=-5

10x=5

Divide both sides by 10.

x = 0.5 = 1/2

Hence, the zeros of the polynomial is 1/2.

Answer:

The answer to your question is below

Step-by-step explanation:

Formula

Triangle's Area = 1/2 bh/2

Trapezoid's area = 1/2 (b1 + b2)h

Parallelogram's area = bh

Rectangle's area = bh

Considering the formulas, we can conclude that:

a) The first choice is true, both formulas have 1/2 in.

b) The second choice is also true, both equations are the same

c) The third choice is incorrect

d) This choice is correct, the bases are added,

e) This choice is incorrect, the sides are not added.

If two cards are drawn without replacement from a 52 card deck, find the probability that the second card drawn is red, given th

snow_lady [41]

Answer:

The probability that the second card drawn is red, given that the first card was a heart is 0.1225

Step-by-step explanation:

Total cards in a deck = 52

Total red cards = 26

Heart cards = 13

Probability of getting red card = $\frac{13}{52}$

Total remaining card = 51

Remaining red cards = 25

Probability of getting red card in second draw without replacement = $\frac{25}{51}$

So, the probability that the second card drawn is red, given that the first card was a heart = $\frac{13}{52} \times \frac{25}{51} =0.1225$

Hence the probability that the second card drawn is red, given that the first card was a heart is 0.1225
