Answer:

Mass of pilot whale is 1.2 X 10 ^4 times massive than Mass of clownfish.

Step-by-step explanation:

Mass of clown fish = 2.5 X 10 ^-1 kg

Mass of pilot whale = 3 X 10 ^ 3 kg

Find the ratio of Mass of pilot whale to the ratio of Mass of clown fish

Mass of pilot whale : Mass of clown fish

3 X 10 ^ 3 : 2.5 X 10 ^-1

It can be written as

3 X 10 ^ 3 / 2.5 X 10 ^-1

1.2 x 10^4

So, Mass of pilot whale is 1.2 X 10 ^4 times massive than Mass of clownfish.

Step 1: Set the two equations equal to each other and solve for x.

3x -5 = 6x - 8

3x + (-5+5) = 6x -8 + 5

(3x - 6x) = (6x - 6x) - 3

-3x/-3  = -3/-3

x = 1

Step 2: To solve for y take one of the given equation of your choice (for the purpose of this explanation I will only do y = 3x - 5) and replace x with 1, then solve for y

y = 3(1) - 5

y = 3 - 5

y = -2

(1,-2)

Check:

-2 = 3(1) - 5 ---> - 2 = -2

-2 = 6(1) - 8 ---> -2 = -2

Hope this helped!

Answer:

x=1

and y= -2

Step-by-step explanation:

y=3x-5 y=6x-8

On equating the two equations:

3x-5= 6x-8

Taking terms of x on one side and constant terms on the other

6x-3x= 8-5

3x= 3

Dividing both sides by 3, we get

x=1

Now, putting value of x in y=3x-5, we get

y=3-5

 = -2

Hence, Solution is:

x=1 and y= -2

Answer:

The equation is:

[tex]S=\frac{a_n*r-a_1}{r-1}[/tex]

[tex]S=\frac{\frac{16}{243}*\frac{2}{3}-\frac{1}{3}}{\frac{2}{3}-1}[/tex]

The sum is:

[tex]S=\frac{211}{243}[/tex]

--------------------------------------------------------------------

If the sequence is infinite, the formula is:

[tex]S = \frac{a_1}{1-r}[/tex]

-------------------------------------------------------------------

Step-by-step explanation:

We must calculate the radius of the geometric series

[tex]r =\frac{a_{n+1}}{a_n}\\\\r=\frac{\frac{2}{9}}{\frac{1}{3}}\\\\r=\frac{2}{3}[/tex]

The first term of the series is: [tex]a_1=\frac{1}{3}[/tex]

The last term of the series is: [tex]a_n=\frac{16}{243}[/tex]

If the sequence is finite then the formula is:

[tex]S=\frac{a_n*r-a_1}{r-1}[/tex]

[tex]S=\frac{\frac{16}{243}*\frac{2}{3}-\frac{1}{3}}{\frac{2}{3}-1}[/tex]

[tex]S=\frac{211}{243}[/tex]

If the sequence is infinite then by definition as the radius  are [tex]0 <| r | <1[/tex] then the formula for the sum of the geometric sequence is:

[tex]S = \frac{a_1}{1-r}\\\\S = \frac{\frac{1}{3}}{1-\frac{2}{3}}\\\\S =1[/tex]

The slope is 4

EXPLANATION

We want to find the slope of the line goin through (3,9) and (1,1)

We use the slope formula:

[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]

We substitute the points into the slope formula to get;

[tex]m = \frac{1 - 9}{1 - 3} [/tex]

This simplifies to:

[tex]m = \frac{ - 8}{ - 2} [/tex]

[tex]m = 4[/tex]

Hence the slope of the line is 4.

Answer:

4

Step-by-step explanation:

Final answer:

The expression equivalent to (X^3)^4 is X^12. You calculate this by multiplying the exponents, resulting in X raised to the power of 3 times 4, which equals 12.

Explanation:

The expression (X^3)^4 is equivalent to X^(3*4), which is X^12. This follows the rule that when you raise a power to a power, you multiply the exponents. A number raised to the fourth power, like in this case, means that number is multiplied by itself four times. Generalizing this, for any base 'n' and exponents 'a' and 'b', the expression (n^a)^b is equal to n^(a*b).

For example, similar to (5^3)^4 being 5^(3*4) or 5^12, which is twelve fives multiplied together. Therefore, our given expression simplifies to X multiplied by itself a total of twelve times.

Answer:

x-6

Let the number be x

Then the algebraic expression  “six less than a number” can be represented as:

x - 6

So, "six less than a number” can be represented as: x - 6

The answer is:

The domain for the function is all the real numbers,

Domain:(-∞,∞)

Since we are working with fractions, the only restriction that we will have for the function is when the denominator of the function tends to 0.

We are given the function:

[tex]f(x)=\frac{1}{x^{2}-5x+25 }[/tex]

Where, the denominator is given by the expression:

[tex]x^{2}-5x+25[/tex]

For the given expression (quadratic equation), we have that:

[tex]a=1\\b=-5\\c=25[/tex]

Calculating the discriminat of the quadratic function, in order to know if the denominator of the function has roots (zeroes) at the real numbers, we have:

[tex]Discriminant=b^{2} -4ac[/tex]

[tex]Discriminant=-5^{2} -4(1)(25)[/tex]

[tex]Discriminant=25 -100=-75[/tex]

Now, as we know, if the discriminant of a quadratic function is less than 0, the quadratic function has no roots in the real numbers.

Therefore, since the denominator (quadratic function) has no roots in the real numbers, the domain for the function will be equal to all the real numbers.

Domain:(-∞,∞)

Hence, the answer is the third option, the domain for the function is all the real numbers,

Domain:(-∞,∞)

Answer:

Blank 1 ⇒ supplementary

Blank 2 ⇒ complementary

Step-by-step explanation:

* Lets revise some facts to solve the problem

- The tangent to a circle is a line touch the circle at one point

- The tangent and the radius of a circle are perpendicular to each

 other at the point of contact

- If the two angles are supplementary, then the sum of their measure

 is 180°

- If the two angles are complementary, then the sum of their measure

 is 90°

* Now lets solve the question

∵ CB and CA are two tangents to the circle O at B and A

∵ OB and OA are radii

∴ OB ⊥ BC at point B and OA ⊥ AC at point A

∴ m∠OBC = 90° and m∠OAC = 90°

- In figure CBOA is a quadrilateral

∴ The sum of the measures of its interior angles is 360°

∵ m∠CBO + m∠BOA + m∠OAC + m∠BCA = 360°

∵ m∠CBO = 90° , m∠OAC = 90°

∴ 90° + m∠BOA + 90° + m∠BCA = 360°

∴ 180° + m∠BOA + m∠BCA = 360° ⇒ subtract 180 from both sides

∴ m∠BOA + m∠BCA = 180°

∴ ∠BOA and ∠BCA are supplementary

- In Δ CBO

∵ The sum of the measures of the interior angles of any triangle is 180°

∴ m∠BOC + m∠BCO + m∠CBO = 180°

∵ m∠CBO = 90°

∴ m∠BOC + m∠BCO + 90° = 180° ⇒ subtract 90° from both sides

∴ m∠BOC + m∠BCO = 90°

∴ ∠BOC and ∠BCO are complementary

Hope this helps!

So, 1 cube equals 1/4 unit.

4 cubes will equal 1 whole unit.

If the volume of the rectangular prism is 3 cubic units, all you have to do is multiply.

Answer: C

Step-by-step explanation: i got 100% on test

The probability of drawing 3 oranges from a basket of 6 oranges and 4 tangerines is 1/6 or approximately 0.167.

This problem is a probability question in the field of mathematics. It is asking us to find the probability that all three fruits drawn from the basket are oranges. This can be solved using the concept of combinations from probability theory.

The total number of fruits in the basket is 10 (6 oranges and 4 tangerines). We want to draw a sample of 3 fruits. The number of ways to draw 3 fruits from a total of 10 (regardless of type) is given by the combination formula C(n, r), where n is the total number of items and r is the number of items to choose. So we have C(10, 3) = 120 possible ways.

Next, consider the scenario we're interested in--drawing 3 oranges. The total number of ways to draw 3 oranges from a total of 6 oranges is C(6, 3) = 20 possible ways.

So, the probability of drawing 3 oranges is the number of ways to draw 3 oranges divided by the total number of ways to draw 3 fruits. So, the probability is 20/120 = 1/6 or approximately 0.167.

Final answer:

The probability of drawing 3 oranges from a basket containing 6 oranges and 4 tangerines is found using combinations. The calculation shows that the probability of selecting all oranges in a draw of 3 fruits is 1/6.

Explanation:

The question asks to find the probability that when three fruits are drawn from a basket containing 6 oranges and 4 tangerines, all three are oranges. This is a problem of probability without replacement, which can be solved using combinations.

To find the probability of drawing 3 oranges out of 3 fruits, we calculate the combinations of choosing 3 oranges from 6 and then divide it by the combinations of choosing 3 fruits from the total 10 fruits in the basket.

The number of ways to select 3 oranges out of 6 is given by the combination formula C(n, k) = n! / (k!(n - k)!), where n is the total number of items, and k is the number of items to choose. So, we have:

Ways to pick 3 oranges: C(6, 3)

Total ways to pick 3 fruits: C(10, 3)

Then the probability is calculated by:

P(all oranges) = C(6, 3) / C(10, 3)

Calculating the combinations, we have:

Thus, the probability that all three fruits are oranges is 1/6.

Step-by-step explanation:

By the Angles of Intersecting Chords Theorem, When two chords intersect inside a circle, then the measure of the angle formed is one half the sum of chord's intercepted arcs.

In the diagram : -

⇒ ∠ 1 = 38°

Now, again by the diagram,

∠1 and ∠2 are linear pairs,

⇒ ∠1 + ∠2 = 180°

⇒ 38° + ∠2 = 180°

⇒ ∠2 = 142°

Answer:

38,142.

Step-by-step explanation:

The measure of angle 1 = the sum of the measure of the 2 arcs / 2

= (36 + 40) / 2

= 38 degrees.

Answer:

D

Step-by-step explanation:

Supplementary angles sum to 180°

Subtract the given angle from 180 for the supplement, that is

180° - 89° = 91° ← the supplementary angle

Final answer:

The supplement of an 89° angle is found by subtracting it from 180°, giving us 91°. Therefore, the correct answer is 91°, which is option D.

Explanation:

To find the supplement of an angle, we need to know that supplementary angles add up to 180 degrees. Given an angle that measures 89°, we can find its supplement by subtracting the given angle from 180°.

So, 180° - 89° = 91°.

The supplement of an angle that measures 89° is 91°, which corresponds to option D.

9x²+18x+9 = 144

9x²+18x = 135

x²+2x = 15

x(x+2) = 15

x = 3

x= -5

Answer: [tex]x_1=3\\x_2=-5[/tex]

Step-by-step explanation:

Divide boht sides of the eqeuation by 9:

[tex]\frac{9(x+1)^2}{9}=\frac{144}{9}\\\\(x+1)^2=16[/tex]

Remembert that:

[tex](a+b)^2=a^2+2ab+b^2[/tex]

Then, applying this, you get:

[tex]x^2+2(x)(1)+1^2=16\\x^2+2x+1=16[/tex]

Subtract 16 from both sides:

[tex]x^2+2x+1-16=16-16\\x^2+2x-15=0[/tex]

3 a (3 - a) = 9 a - 3 a^2:

9 a - 3 a^2 + 3 (a^2 - 3) + 3 a

3 (a^2 - 3) = 3 a^2 - 9:

3 a^2 - 9 - 3 a^2 + 9 a + 3 a

Grouping like terms, 3 a^2 - 3 a^2 + 9 a + 3 a - 9 = (9 a + 3 a) - 9 + (-3 a^2 + 3 a^2):

(9 a + 3 a) - 9 + (-3 a^2 + 3 a^2)

9 a + 3 a = 12 a:
