Answer:

13.9

Step-by-step explanation:

Use the distance formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\\\d = \sqrt{(7 - (-5))^2 + (-4-3)^2}\\d = \sqrt{(12)^2 + (-7)^2}\\d = \sqrt{144 + 49}\\d = \sqrt{193}\\[/tex]

The square root of 193 rounded to the nearest tenth is 13.9.

Answer:

2.478x10^7

Step-by-step explanation:

They give you each radius, so you just add them together.

15,300,000+9,480,000=24,780,000 = 2.478x10^7

(or)

1.53x10^7+0.948x10^7= 2.478x10^7

Answer:

Step-by-step explanation:

i). [tex]\frac{48a^3}{6a}=\frac{6\times 8\times a\times a^2}{6a}[/tex]

          [tex]=\frac{6a}{6a}\times 8a^2[/tex]

          = 8a²

ii). [tex]\frac{72a^3b^4c^5}{8ab^2c^3}[/tex] = [tex]\frac{8\times 9\times a\times a^2\times b^2\times b^2\times c^2\times c^3}{8ab^2c^3}[/tex]

                = [tex]\frac{8ab^2c^3}{8ab^2c^3}\times 9a^2b^2c^2[/tex]

                = 9a²b²c²

Answer:

197

Step-by-step explanation:

So, if you catch 100 fish on both days, that means that you have caught 200 fish. 100 on one day and 100 on the next. But, since you've caught 3 fish twice, that means that three out of 200 fish are the same and cannot be counted as new fish. So 3 from 200 is 197 fish. Hope this helped!

Day 1: 100 (3 tagged)

Day 2: 97 (3 tagged)

100+97=197

or

Day 1: 100 (3 tagged)

Day 2: 100 (3 tagged)

100+100= 200

200-3=197

Answer, 197 fish.

2x - 15 ≥ 4y

Step-by-step explanation:

Answer:

"A translation of 7 units to the left followed by a translation of 1 unit down".

Step-by-step explanation:

There are multiple transformations that map one point into another, here is one example that works particularly for translations, which are the simplest (and usually the most used) transformations.

Suppose that we have the point (a, b) which is transformed into (a', b')

Then we have a horizontal translation of (a' - a) units followed by a vertical translation of (b' - b) units.

(the order of the translations does not matter, is the same having first the vertical translation and then the horizontal one).

Here we have the point A (3, 4) transformed into (-4, 3)

Then we have a horizontal translation of ((-4) - 3) = -7 units followed by a vertical translation of (3 - 4) = -1 units.

Where a horizontal translation of -7 units is a translation of 7 units to the left, and a vertical translation of -1 unit is a translation of 1 unit down.

Then we can write this transformation as:

"A translation of 7 units to the left followed by a translation of 1 unit down".

Answer:

[tex]P(White\ and\ Purple) = 2.52\%[/tex]

Step-by-step explanation:

Given

[tex]Purple = 18[/tex]       [tex]Green = 34[/tex]         [tex]White = 14[/tex]

[tex]Blue = 26[/tex]          [tex]Black = 8[/tex]

Required

Probability of first selecting white and then selecting purple

The total boxes is:

[tex]Total = 18+34+14+26+8[/tex]

[tex]Total = 100[/tex]

The probability is represented as:

[tex]P(White\ and\ Purple)[/tex]

And the solution is:

[tex]P(White\ and\ Purple) = P(White) * P(Purple)[/tex]

[tex]P(White\ and\ Purple) = \frac{n(White)}{Total} * \frac{n(Purple)}{Total}[/tex]

[tex]P(White\ and\ Purple) = \frac{14}{100} * \frac{18}{100}[/tex]

[tex]P(White\ and\ Purple) = \frac{14*18}{100*100}[/tex]

[tex]P(White\ and\ Purple) = \frac{252}{10000}[/tex]

[tex]P(White\ and\ Purple) = 0.0252[/tex]

or

[tex]P(White\ and\ Purple) = 2.52\%[/tex]

Step-by-step explanation:

Answer:

cos 2x = (√7) / 4

Step-by-step explanation:

sin x - cos x = 1/2

(sin x - cos x)² = (1/2)²

sin²x - 2 sin x cos x + cos² x = 1/4

1 - 2 sinx cosx = 1/4

2 sinx cosx = 3/4

sin 2x = 2 sinx cosx = 3/4

sin² 2x = 9/16

cos² 2x = 1 - sin² 2x = 1 - 9/16 = 7/16

cos 2x = (√7) / 4

Answer:

x= -8

Step-by-step explanation:

Move the terms

Calculate: -x=12-4 = -x=8

Change the signs

Answer:

a) -2 < 3

b) |-12| < |15| (the absolute value of -12 is 12 so that's comparing 12 to 15)

c) 3 > -4

d) |15| > |-12|

e) 7 > -11

Answer:

number of term is 21

Step-by-step explanation:

Please mark as brainliest

Answer:

21

Step-by-step explanation:

The first numbers we ever learn to count with are the ones on our fingers - 1, 2, 3, 4, and on and on and on. Wouldn't it be nice, then, if we could somehow transform this sequence into that one that's so familiar to us? If we could do that, we could find the number of terms just by looking at the last one.

Arithmetic sequences evolve predictably - we start with a specific number and continue adding another number (called the common difference) to one term to get the next.

Here, our common difference is 3, since 8 + 3 = 11, 14 + 3 = 17... you get the picture. If we ultimately want to get our sequence down to the counting numbers (1, 2, 3...) we should start by getting them down to the multiples of 3 (3, 6, 9...). To do that, we'll subtract 5 from each term in the sequence. This gets us from

8, 11, 14, 17, ... 68

to

3, 6, 9, 12, ... 63

From here, we'll divide each term by 3, finally giving us back a sequence of counting numbers:

1, 2, 3, 4, ... 21

Now, we can look at the last term sequence to find that there are 21 terms in it.

Answer:‍♀️

Step-by-step explanation:

Answer:

The other factor is (x - 2)

Step-by-step explanation:

One quick way to solve this is to factor the polynomial and see what you get:

3x² – 10x + 8

= 3x² - 6x - 4x + 8

= 3x(x - 2) - 4(x - 2)

= (3x - 4)(x - 2)

You can also solve this using long division:

[tex]\ \ \ \ \ \ \ \ \ \ \underline{x - 2\ \ \ \ \ \ \ \ \ \ \ \ \ \ } \\3x - 4\ )3x^{2} - 10x + 8\\.\ \ \ \ \ \ \ \ \ \ \underline{3x^2 - 4x}\\.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ -6x + 8\\.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \underline{-6x + 8}\\.\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0R[/tex]
