y-3=4(x-10)

Step-by-step explanation:

Point Slope Form: y-y1=m(x-x1)

Where m=slope and (x1, y1) is a point on the line.

m=(y2-y1)/(x2-x1)=(11-3)/(12-10)=8/2=4

So the slope is 4,

Answer:

In the Pascal Expansion of [tex](x+3)^4[/tex] the third term is [tex]54x^2[/tex].

Step-by-step explanation:

Here, the given expression is given as [tex](x+3)^4[/tex]

Now, by the PASCAL'S TRIANGLE EXPANSION:

[tex](a + b)^4 = 1(a)^4 + 4(a)^3b + 6(a)^2b^2 + 4(a)b^3 + 1b^4\\= 1 + 4b + 6a^2 + 4b^3 + b^4.[/tex]

Substituting a  = x and b = 3, we get:

[tex](x + 3)^4 = 1(x)^4 + 4(x)^3(3) + 6(x)^2(3)^2 + 4(x)(3)^3 + 1(3)^4\\= x^4 + 12x^3 + 54x^2  + 108x+ 81[/tex]

In the given expansion, the third term is [tex]54x^2[/tex].

Hence, in the Pascal Expansion of [tex](x+3)^4[/tex] the third term is [tex]54x^2[/tex].

Final answer:

The third term is 6 times x squared times 3 squared, which simplifies to 54x².

Explanation:

To use Pascal's Triangle to determine the third term of the expansion of (x + 3)⁴, we first need to look at the row of Pascal's Triangle that corresponds to the exponent 4. This is the fifth row if we start counting from 0 and it reads 1, 4, 6, 4, 1. We use these coefficients for each term of the expansion, which follows the pattern (a + b)ⁿ = C(n,0)*aⁿ + C(n,1)*a⁽ⁿ⁻¹⁾b + C(n,2)*a⁽ⁿ⁻²⁾b² + ... + C(n,n)*bⁿ, where C(n,k) is the binomial coefficient from Pascal's Triangle.

So, the third term in the expansion is given by the third coefficient (counting from 0) from the row, which is 6, multiplied by x raised to power 4 - 2 times 3 squared. Therefore, the third term is 6x²·3², which simplifies to 54x².

Answer:

57

Step-by-step explanation:

The bottom line of the triangle is 180 degrees. Therefore, 2y + 4y - 36 has to equal 180. So, once you solve this linear equation, you will find that y equals 36. A triangle's angles always equal a total of 180 degrees. So, x + 51 + 2y has to equal 180, as well. Since we know y, substitute in 36 for 2y. Now the equation is 51 + 72 + x = 180. Solve for x. X is 57.

Answer:

57°

Step-by-step explanation:

The angles that are at the bottom middle are on a straight line, so they must add up to 180°. In order to determine y, use the equation 180 = 2y + 4y -36. After solving for y, you should be left with 36 = y. Now, we can fill in the bottom right angle in the left triangle. This would be 36 times 2, or 72. In triangles, all angles always add up to 180°, so, we can use the equation 180 = x + 51 + 72. Once solved for x, this will leave you with 57 = x, our final answer.

Step-by-step explanation:

Answer:

4.8

12 x 40

100

= 4.8

Step-by-step explanation:

The percentage of beings that preferred hab juice, is 30% of beings preferring hab juice.

The question is asking to find the percentage of beings that preferred hab juice out of a total of 40 surveyed on planet Tott. To do this, we use the basic formula for percentage:

Percentage = (Part / Whole) * 100

In this case, 12 beings out of 40 preferred hab juice. So we have:

Percentage = (12 / 40) * 100 = 0.3 * 100 = 30%

Therefore, 30% of the beings surveyed preferred hab juice.

Answer:

Distance from point A(0,5) to y = -3 x  - 5 is √10 units units.

Step-by-step explanation:

Here, the given line equation is  y = -3x -5

Also, the point A (0,5) is the given point.

Now, a distance of a point (m,n)  from a line Ax + By + c = 0 is given as:

[tex]d = \frac{\mid Am +bn+c \mid}{\sqrt{A^2 + B^2} }[/tex]

Here, the equation is  y = -3 x -5

⇒ 3 x + y + 5 = 0  , here A  = 3, B = 1

Now, the value of line equation at (0,5) is  3(0) + 5 + 5 = 10

So, from the given distance formula,  we get:

[tex]d = \frac{\mid Am +bn+c \mid}{\sqrt{A^2 + B^2} }  = d = \frac{10}{\sqrt{(3)^2 + (1)^2} } = \frac{10}{\sqrt{(10)}}   = \sqrt{(10)}[/tex]

⇒ d  = √10 units

Hence, distance from point A(0,5) to y = -3 x  - 5 is √10 units units.

To find the distance from point A(0,5) to the line y=-3x-5, we can use the distance formula.

To find the distance from point A(0,5) to the line y=-3x-5, we can use the distance formula.

The distance formula is given by:

d = √((x2 - x1)² + (y2 - y1)²)

In this case, point A is (0,5) and the line is y = -3x - 5.

So, we can substitute the values into the formula:

d = √((x - 0)² + (y - 5)²)

d = √(x² + (y - 5)²)

To find the distance, we need to substitute the x and y values of a point on the line into the formula and solve for d.

Let's take the point (1, -8) as an example:

d = √((1)² + (-8 - 5)²)

d = √(1 + 169)

d = √170

So, the distance from point A(0,5) to the line y=-3x-5 is √170.

Answer:

The diameter of the circle is B) 24 inches.

Step-by-step explanation:

The value given (12 inches) is the radius of the circle. The diameter of a circle is equal to 2 * radius. 2 * 12 = 24.

The diameter of the circle is 24 inches.

Option B is the correct answer.

We have,

The diameter of a circle is a line segment that passes through the center of the circle and connects two points on its circumference.

It is the longest chord of the circle and divides the circle into two equal halves.

The diameter is commonly denoted by the symbol "d" and is related to the radius of the circle (denoted by "r") by the equation:

d = 2r

Now,

r = 12 inches

So,

d = 2r = 2 x 12 inches

d = 24 inches

d = 24 inches

Thus,

The diameter of the circle is 24 inches.

The explicit rule is Ak = 1 + 2 * (k - 1)

Step-by-step explanation:

1. Let's review the information provided to us for finding the explicit rule for the sequence.

The arithmetic sequence 1, 3, 5, 7, 9, . . . represents the set of odd natural numbers.

2. Let's find the solution:

Ak = 1 + 2 * (k - 1)

For k = 1 ⇒ Ak = 1 + 2 * (1 - 1) = 1 + 2 * 0 = 1 + 0 = 1

For k = 2 ⇒ Ak = 1 + 2 * (2 - 1) = 1 + 2 * 1 = 1 + 2 = 3

For k = 3 ⇒ Ak = 1 + 2 * (3 - 1) = 1 + 2 * 2 = 1 + 4 = 5

For k = 4 ⇒ Ak = 1 + 2 * (4 - 1) = 1 + 2 * 3 = 1 + 6 = 7

For k = 5 ⇒ Ak = 1 + 2 * (5 - 1) = 1 + 2 * 4 = 1 + 8 = 9

For k = 6 ⇒ Ak = 1 + 2 * (6 - 1) = 1 + 2 * 5 = 1 + 10 = 11

For k = 7 ⇒ Ak = 1 + 2 * (7 - 1) = 1 + 2 * 6 = 1 + 12 = 13

Answer:

x=27°

Step-by-step explanation:

we know that

The Triangle Exterior Angle Theorem, states that: An exterior angle of a triangle is equal to the sum of the opposite interior angles

step 1

Find the measure of angle PLM

we know that

m∠PLM+m∠LPM=m∠PMN ----> by Triangle Exterior Angle Theorem

we have

m∠LPM=x°

m∠PMN=2x+72°

substitute

m∠PLM+x=2x+72°

m∠PLM=2x-x+72°

m∠PLM=x+72°

step 2

Find the measure of angle x

we know that

3x+m∠PLM=180° ----> by supplementary angles (form a linear pair)

we have

m∠PLM=x+72°  (see step 1)

substitute

3x+x+72°=180°

4x=180°-72°

4x=108°

x=27°

Answer:

By the given diagram,

PLM is a triangle,

K and N are points on line MN,

m∠KLP = 3x, m∠P = x, m∠PMN = 2x + 72°

We need to give the reasons in the steps of finding the value of x.

For this we have to know the following properties :

Linear pairs: Adjacent angles which are supplementary.

Subtraction property of equality : We can subtract a number or expression in both sides of an equation.

i.e. a = b ⇒ a + c = b + c

Exterior angle theorem : exterior angle formed by extending the side of a triangle is equal to the sum of its non-adjacent angles.

Thus, the steps of finding value of x are as follow,

1. m∠KLP+m∠PLM = 180°       ( linear pairs )

2. 3x +m∠PLM = 180°              ( Substitution)

3. m∠PLM = 180° - 3x              ( Subtraction property of equality)

4. m∠PMN=m∠P+m∠PLM      ( Exterior angle theorem )

5. 2x + 72° = x + 180° - 3x        ( Substitution)

6. 2x + 72° = 180° - 2x              ( Solving )

   2x = 180° - 2x - 72°  

   2x + 2x = 108°

   4x = 108°

   x   = 27°

Step-by-step explanation:

Answer: Here we will tell you what 630 is rounded to the nearest hundred and also show you what rules we used to get to the answer.

Remember, we did not necessarily round up or down, but to the hundred that is nearest to 630.

First, 630 rounded to the nearest hundred is: 600

When rounding to the nearest hundred, like we did with 630 above, we use the following rules:

A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

Step-by-step explanation:

Rounding 630 to the nearest hundred results in 600.

To round the number 630 to the nearest hundred, consider the tens digit of the number.

In this case, the tens digit is 3.

If the tens digit is 5 or greater, you round up to the next hundred.

If the tens digit is 4 or less, you round down to the current hundred.

Since the tens digit in 630 is 3, which is less than 5, you round down.

Therefore, rounding 630 to the nearest hundred results in 600.
