1 - 2.25x^8 Factor this

Mathematics
1 answer:
Yuliya22 [10]3 years ago
7 0

Answer:

(1+3/2x^4)(1-3/2x^4) = (1+1.5x^4)(1-1.5x^4)

Step-by-step explanation:

2.25 = 9/4

putting decimals into fractions will make this easier

9/4 = 3/2 * 3/2

a²-b² = (a+b)(a-b)

1 - 2.25x^8 = 1²-(3/2x^4)² = (1+3/2x^4)(1-3/2x^4) = (1+1.5x^4)(1-1.5x^4)

Zanzabum

Answer:

a.V=5/6T

b. 350 ml

Step-by-step explanation:

a.

V∝T

or V=kT

where k is a constant.

V=250 ml

T=300° K

250=300 k

k=250/300=5/6

so V=5/6 T

b.

V=5/6 T

=5/6×420

=5×70

Find the value of x.<br> If necessary, you may learn what the markings on a figure indicate.<br> 74°
marissa [1.9K]

Answer:

x = 61

Step-by-step explanation:

Left hand triangle containing 1 angle of 74

Label the other angle opposite the marked side also as 74

Find the third angle. Call it y.

y + 74 + 74 = 180           Combine like terms

y + 148 = 180                 Subtract 148 from both sides.

y = 180 - 148

y = 32

=============

Now work with the triangle on the right.

label the angle making up the right angle = z

32 + z = 90                             These two angles are complementary = 90

32 - 32 + z = 90 - 32              Subtract 32 from both sides

z = 58                                      Use 58 wherever you see z

x + x + z = 180                         Substitute

2x + 58 = 180                          Subtract 58 from both sides

2x = 122                                  Divide by 2

x = 61

Ross chose a card at random from a deck of 52 cards. Ross replaced the card and then chose a second card. What is the probabilit
DaniilM [7]

Answer:

\frac{1}{208}

Step-by-step explanation:

We have been given that Ross chose a card at random from a deck of 52 cards. Ross replaced the card and then chose a second card.

Let us find probability of getting a club.

\text{ Probability of getting a club}=\frac{13}{52} =\frac{1}{4}

Now let us find probability of getting the ace of spades.

\text{ Probability of getting ace of spades}=\frac{1}{52}

Now let us multiply these to find probability of getting a club and ace of spades.      

\text{ Probability of getting a club and then ace of spades}=\frac{1}{4}*\frac{1}{52}=\frac{1}{208}

Therefore, probability of getting a club and then the ace of spades \frac{1}{208}.
