Answer:

88%.

Step-by-step explanation:

Multiply the fraction by 100:

(22/25) * 100

= 22 * 4

= 88%.

Answer:

Step-by-step explanation:

3x²=15-4x

divide by 3 on both sides

x²=5-\(\frac{4}{3}\)x ​ ​

move everything to one side

x²+\(\frac{4}{3}\)x ​-5 = 0

add the square of 1/2 the middle term of \(\frac{4}{3}\)  but also subtract it too

x²+\(\frac{4}{3}\)x +\(( \frac{2}{3} )^{2}\)​-5-\(( \frac{2}{3} )^{2}\)​ = 0

now use the property of a perfect square to rewrite

\((x+\frac{2}{3}) ^{2}\) -5 -\(\frac{4}{9}\) = 0

rewrite 5 as a fraction

\((x+\frac{2}{3}) ^{2}\) - \(\frac{45}{9}\)- \(\frac{4}{9}\) = 0

add up the fractions

\((x+\frac{2}{3}) ^{2}\) - \(\frac{49}{9}\) = 0

move to the other side

\((x+\frac{2}{3}) ^{2}\) = \(\frac{49}{9}\)

take the square root of both sides :P

\(\sqrt{((x+\frac{2}{3}) ^{2} }\)  = \(\sqrt{\frac{49}{9} }\)

much easier looking now, just use algebra to solve for x

x + \(\frac{2}{3}\) = \(\frac{7}{3}\)

subtract  \(\frac{2}{3}\)  from both sides

x + \(\frac{2}{3}\) -  \(\frac{2}{3}\) = \(\frac{7}{3}\) - \(\frac{2}{3}\)

x = \(\frac{5}{3}\)

:)

Answer:

x = - 3, x = \(\frac{5}{3}\)

Step-by-step explanation:

Given

3x² =15 - 4x ( add 4x to both sides )

3x² + 4x = 15 ← factor out 3 from each term on the left side

3(x² + \(\frac{4}{3}\) x) = 15

To complete the square

add/subtract ( half the coefficient of the x- term)² to x² + \(\frac{4}{3}\) x

3(x² + 2(\(\frac{2}{3}\) )x + \(\frac{4}{9}\) - \(\frac{4}{9}\) ) = 15

3(x + \(\frac{2}{3}\) )² - \(\frac{4}{3}\) = 15 ( add \(\frac{4}{3}\) to both sides )

3(x + \(\frac{2}{3}\) )² = 15 + \(\frac{4}{3}\) = \(\frac{49}{3}\) ( divide both sides by 3 )

(x + \(\frac{2}{3}\) )² = \(\frac{49}{9}\) ( take the square root of both sides )

x + \(\frac{2}{3}\) = ± \(\sqrt{\frac{49}{9} }\) = ± \(\frac{7}{3}\) ( subtract \(\frac{2}{3}\) from both sides )

x = - \(\frac{2}{3}\) ± \(\frac{7}{3}\), then

x = - \(\frac{2}{3}\) - \(\frac{7}{3}\) = - 3

x = - \(\frac{2}{3}\) + \(\frac{7}{3}\) = \(\frac{5}{3}\)

Answer:

Second term of this sequence: \(10\).

Third term of this sequence: \(20\).

Step-by-step explanation:

The first step is to find the common ratio of this sequence.

In a geometric sequence, multiply one term by the common ratio to find an expression for the next term. Let \(r\) denote the common ratio of this sequence. For this sequence:

However, the question states that the value of the fourth term is \(40\). In other words, \(5\, r^{3} = 40\).

Solve this equation for \(r\):

\(r^{3} = 8\).

\(r = 2\).

(Since the power of \(r\) is non-even in the equation, there's no need to consider the sign of \(r\!\) when taking the cube root.)

Substitute \(r = 2\) into the expression for the second term and the third term to find their values:

The limit of the difference quotients for f(x) = x^2 + 2x + 1 as x approaches -1 is indeterminate.

To find the limit of the difference quotients for the function f(x) = x^2 + 2x + 1 as x approaches -1, we need to evaluate the following expression:

lim(x→-1) [f(x) - f(-1)] / (x - (-1))

First, let's substitute the values into the expression:

lim(x→-1) \([(x^2 + 2x + 1) - (-1^2 + 2(-1) + 1)] / (x + 1)\)

Simplifying further:

lim(x→-1) \([(x^2 + 2x + 1) - (1 - 2 + 1)] / (x + 1)\)

lim(x→-1)\([x^2 + 2x + 1 - 0] / (x + 1)\)

lim(x→-1) \((x^2 + 2x + 1) / (x + 1)\)

Now, we can directly substitute x = -1 into the expression:

\((-1^2 + 2(-1) + 1) / (-1 + 1)\)

(1 - 2 + 1) / (0)

0 / 0

We have obtained an indeterminate form of 0/0. This indicates that we need to further simplify the expression or use other techniques, such as L'Hôpital's rule, to evaluate the limit. However, without additional information or simplification, we cannot determine the precise value of the limit at x = -1.

By using the concept of circle, it can be concluded that-

Center = (1, 0) lies on x axis

The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

What is a circle?

Circle is a two dimensional round figure in which every point on the circle maintains a fixed distance from a point known as the center of the circle and the fixed distance is called radius of the circle

The equation of circle is

\(x^2 + y^2 - 2x - 8 = 0.\)

\(x^2 - 2x + 1 - 1-8+y^2 =0\\(x -1)^2 + y^2 = 9\\(x - 1)^2 + y^2 = 3^2\)

Center = (1, 0) lies on x axis

Radius of the given circle is 3 units

Radius of x² + y² = 9 is 3

Answer:

The two pages that face each other that have a sum of 97 are 48 and 49.

Step-by-step explanation:

Formula for consecutive integers

Page 1 = (n + 1), Page 2 = (n + 2)

(n + 1) + (n + 2) = 97

            2n + 3 = 97

                    2n = 97 - 3

                    2n/2 = 94/2

                        n = 47

(n + 1) = 47 + 1 = 48

(n + 2) = 47 +2 = 49

48 + 49 = 97

Given:

Arithmetic sequence    -5, 13, 31, 49..........

We are to find the explicit formula of the sequence above. An explicit formula provides a binding formula for finding nth term.

To find the formula, we need to know the  first term and the common difference.

The common difference is the difference between each successive terms of the sequence.

In the given sequence, the common difference is 18;

      13-(-5) = 18

      31 - 13 = 18

      49 - 31 = 18

n    calculation of the nth term

1              -5                          -5  +  18(0)  = -5

2             13                          -5   + 18(1)  = 13

3             31                          -5   +  18(2)  = 31

4             49                         -5   +  18(3)  = 49

Since the common difference is 18, we can now derive the formula;

          b(n) = -5 + 18(n-1)

n is the position of the term

Any number in the sequence can be derived using the explicit formula

-5 + 18(n-1)

The given expression \(g^2/3h\) is equivalent to the option (c) \(8g^2/24h\)as we have multiplied 8 in both numerator and denominator.

The given expression is \(g^2/3h\).

Now, to further simplify the expression, we can multiply both numerator and denominator by 8. This gives us:

\((g^2/3h) * (8/8)\)

Simplifying further, we get:

\((8g^2)/(24h)\)

Therefore, the expression equivalent to \(g^2/3h\) is \((8g^2)/(24h)\).

Thus, the given expression \(g^2/3h\) is equivalent to the option (c) \(8g^2/24h\) as we have multiplied 8 in both numerator and denominator.

The numerator is the top part of a fraction, which represents the number of equal parts being considered. It is the value that is above the fraction bar and represents the quantity being divided into equal parts.

The formula of the graph of f(x) = 8x⁴-5x³-2x²+6x+5 is reflected across the y-axis as g(x) = 8x⁴ + 5x³- 2x²-6x + 5 .

A graph can be defined as a pictorial representation or a diagram that represents data or values.

Reflection across the y-axis is defined as reflecting a point across they = x,  the x-coordinate, and y-coordinate places, the line y = -x is the coordinates (-x, y).

So reflected across the y-axis: f(x) → f(-x),

⇒ (x,y) → (-x , y)

We have to determine the equation of the graph of f(x) = 8x⁴-5x³-2x²+6x+5 is reflected across the y-axis.

Since reflected across the y-axis: f(x) → f(-x), So substitute the value x = -x

⇒ f(-x) = 8(-x)⁴-5(-x)³-2(-x)²+6(-x)+5

⇒ f(-x) = 8x⁴ + 5x³- 2x²-6x + 5 = g(x)

Hence, the equation of the graph of f(x) = 8x⁴-5x³-2x²+6x+5 is reflected across the y-axis as g(x) = 8x⁴ + 5x³- 2x²-6x + 5 .

Answer:

The mercury will not freeze because the freezer is warmer than the freezing point of mercury.

Step-by-step explanation:

A "freezing point" is a point that allows a liquid to solidify. This is lower than the melting point (of course). However, specific liquids freeze at varying freezing points.

For example, the freezing point of water is 0°C while the freezing point of Mercury is -39°C. This means that water will only freeze once it reaches a temperature of 0°C or lower than this. Same goes for Mercury–it needs to reach the temperature of -39°C or lower in order to freeze.

In mathematics, the common difference is a term used in arithmetic sequences to refer to the fixed difference between any two consecutive terms in the sequence.

An arithmetic sequence is a sequence of numbers in which each term is obtained by adding a fixed value, called the common difference, to the preceding term.

-34 -21 -8 5 ...

f(1) = -34

f(n) = f(n-1) + [n-2]*13 for n = 2, 3, 4, ...

The common difference between consecutive terms of the sequence is 13.

The first term of the sequence is -34, which is f(1).

To get the nth term of the sequence, we add (n-2)*13 to the (n-1)th term of the sequence.

For example, to get the 2nd term of the sequence, we add (2-2)*13 = 0 to the 1st term, -34, which gives us -34.

To get the 3rd term, we add (3-2)*13 = 13 to the 2nd term, which gives us -21+13 = -8.

Answer: 46.26

Step-by-step explanation:

Since it is a square the sides are all the same, and since it’s a half circle, the dashed line is the diameter of the circle. To find the circumference on a circle, the equation is diameter times pi. 3.14 is commonly used for pi which is what I’m using 3.14, but of you are told to use a different number use that. 9*3.14 is 28.26. Since ther are exactly two half circles in the diameter, here’s no point in dividing by 2. The rest of the perimeter are just 2 sides of the square. So 9+9+28.26 is 46.26.

Step-by-step explanation:

The intersection point of the medians of a triangle is defined to be the centroid.

The solution is Option A.

The centroid of the triangle UVW is the intersection of the medians of the triangles

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as UVW

Now , the median of the triangle from U is given by

The measure of WY = The measure of YV

The median of the triangle from W is given by

The measure of UX = The measure of XV

And , the point in which the three medians of the triangle intersect is known as the centroid of a triangle. It is also defined as the point of intersection of all the three medians

So , median is a line that joins the midpoint of a side and the opposite vertex of the triangle

Hence , the point Z is the intersection of the triangle's medians
