Equivalent 1/4 is equals to 4/16 in fractions.

Equivalent fractions in mathematics are ones that have the same denominator but different numerators. For instance, 2/4 and 3/6 are equivalent fractions since they both equal 1. A fraction is a piece of the total. Equivalent fractions are used to indicate identical parts of the whole.

The equivalent fraction of each fraction can be calculated by multiplying the numerator and denominator by the same integer. Equivalent fractions are ones that denote the same value despite visual disparities. You will have devoured half of a cake, for example, if you take a piece, cut it into two equal pieces, and then eat one of them.

= 1/4 is equivalent to:

= 1/4 * 4/4

= 4/16

The value of x in the equation is 9/7.

To solve the equation 5x + 15 - 2x = 24 - 4x, we need to perform certain steps to isolate the variable x on one side of the equation. Here is the step-by-step process to solve the equation:

Combine like terms on both sides of the equation:

5x - 2x + 15 = 24 - 4x

Simplify the expressions:

3x + 15 = 24 - 4x

Add 4x to both sides of the equation to eliminate the variable from the right side:

3x + 4x + 15 = 24 - 4x + 4x

Simplify the expressions:

7x + 15 = 24

Subtract 15 from both sides of the equation:

7x + 15 - 15 = 24 - 15

Simplify the expressions:

7x = 9

Divide both sides of the equation by 7 to solve for x:

(7x)/7 = 9/7

Simplify the expressions:

x = 9/7

Answer:

Option B

Step-by-step explanation:

Case 1:

When 1 - 4x is positive,

1 - 4x > 7

Subtract 1 from both sides,

  -4x   > 7 -1

    -4x > 6

Divide both sides by (-4), when we divide the inequality by a negative sign , the inequality changes.

       \(\sf x < \dfrac{-6}{4}\\\\\\x < -1.5\)

Case2:

When 1 - 4x is negative,

            -(1-4x) > 7

           -1 + 4x > 7

                  4x > 7 +1

                  4x > 8

                    x > 8÷ 4

                    x > 2

From both the case combined, we get

        x < -1.5 U x > 2

When an object receives an applied net force, the velocity versus time graph will show a change in velocity over time. Therefore, the velocity versus time graph is a useful tool for analyzing the effects of net force on an object's motion.

When an object receives an applied net force, its velocity versus time graph will show the following characteristics:

1. A non-zero slope: The slope of the velocity vs. time graph represents the acceleration of the object. Since a net force is applied, the object will experience acceleration, and the graph will have a non-zero slope.

2. Linear relationship: If the net force applied is constant, the acceleration will also be constant. This results in a linear relationship between velocity and time on the graph. The slope of the graph will indicate the acceleration of the object, which is directly proportional to the net force applied. As the net force increases, the acceleration and slope of the graph will also increase.

3. Positive or negative slope: The direction of the slope depends on the direction of the applied force. If the net force is in the same direction as the object's initial velocity, the slope will be positive, indicating an increase in velocity. If the force is in the opposite direction, the slope will be negative, indicating a decrease in velocity.

In summary, the velocity vs. time graph of an object receiving an applied net force will have a linear relationship with a non-zero slope, which can be either positive or negative depending on the direction of the force.

Answer:

X=7 Y=5

Step-by-step explanation:

The graph of the equation r = 3 + cos(θ) does not represent a traditional conic section and therefore does not have an eccentricity, directrix, or semi-latus rectum.

The conic equation in polar form, r = 3 + cos(θ), represents a graph in polar coordinates. To determine the eccentricity and the type of graph (parabola, hyperbola, or ellipse), we can examine the equation.

The eccentricity (e) of a conic section is defined as the ratio of the distance between the focus and the directrix to the distance from the pole to the focus. However, in the case of the equation r = 3 + cos(θ), the constant term (3) indicates that there is no focus or directrix. Therefore, we cannot determine the eccentricity, and the graph does not represent a traditional conic section such as a parabola, hyperbola, or ellipse.

The distance from the pole to the directrix is not applicable in this case since there is no directrix.

Similarly, the semi-latus rectum (s) is a characteristic of conic sections that represents half the length of the chord passing through the focus and perpendicular to the major axis. Since there is no focus in the equation r = 3 + cos(θ), the concept of a semi-latus rectum is not applicable.

Step-by-step explanation:

sum of angles of triangle is 180:

2k + k + 45 + 180   then 3k = 135

all triangles have 180 degrees, so

k = (180 - 45)/3

The pH of the solution of the base is given as follows:

8.23.

To find the pH of a weak base solution, we need to first find the pKb value, which is the negative logarithm of the base dissociation constant Kb. The relationship between Kb and Ka (acid dissociation constant) is:

Kw = Ka x Kb

where Kw is the ion product constant of water, which is 1.0 x 10^-14 at 25°C.

Taking the negative logarithm of both sides, we get:

-pKw = -pKa - pKb

Since pKw is 14.00 at 25°C, we can substitute this value and solve for pKb:

14.00 = -log(1.0 x 10^-14) = -log(Ka x Kb) = -log(Ka) - log(Kb)

log(Kb) = 14.00 + log(Ka)

pKb = -log(Kb) = -14.00 - log(Ka)

We're given that the base is weak, so we can assume that its dissociation constant Kb is small compared to 1.0, meaning that its pKb is large. Thus, we can approximate -log(Kb) as just -log(5.5 x 10^-6) = 5.26.

Now we can use the expression for the pH of a weak base solution:

pH = pKb + log([conjugate acid]/[weak base])

In this case, the weak base is the only species present in solution, so [conjugate acid] is zero, and we can simplify the expression to:

pH = pKb + log([OH-])

in which [OH-] is the concentration of hydroxide ions produced by the weak base in solution. We can find [OH-] using the expression for the base dissociation constant:

Kb = [OH-]^2 / [weak base]

Isolating [OH-]:

[OH-] = sqrt(Kb x [weak base])

[weak base] is given as 0.38 M, hence:

[OH-] = sqrt(5.5 x 10^-6 x 0.38) = 1.40 x 10^-3 M

Finally, we can calculate the pH:

pH = pKb + log([OH-]) = 5.26 + log(1.40 x 10^-3) = 8.23

Therefore, the pH of a 0.38 M solution of this weak base is approximately 8.23.

The analysis of variance is a valuable tool for examining potential differences among three or more groups, helping to make informed decisions based on data. It enables researchers to determine if there is a significant factor affecting the outcome or if the observed variations are simply due to chance.

The analysis of variance (ANOVA) procedure is a statistical technique used to test hypotheses about the means of three or more groups. ANOVA compares the variance within each group to the variance between the groups to determine if there is a significant difference in means. This test is commonly used in research studies to determine if a particular treatment or intervention has an effect on the outcome of interest.

In an ANOVA, the null hypothesis assumes that all group means are equal, while the alternative hypothesis suggests that at least one group mean is different from the others. By calculating the F-statistic and comparing it to a critical value, we can determine whether to reject or fail to reject the null hypothesis.

The distance between successive fourth roots of the complex number √3/2 - 1/2i on the unit circle is 5π/24 units.

To find the distance between successive fourth roots of a complex number on the unit circle, we can use the concept of the angle between the roots. Let's proceed step by step:

The given complex number is √3/2 - 1/2i. This complex number lies on the unit circle because its magnitude is equal to 1.

1. Convert the given complex number to trigonometric form:

  √3/2 - 1/2i = cos(θ) + i*sin(θ)

  By comparing the real and imaginary parts, we can determine the angle θ:

  cos(θ) = √3/2

  sin(θ) = -1/2

  Using the unit circle, we can find that θ = 5π/6 (or 150 degrees). This angle represents the position of the given complex number on the unit circle.

2. Find the angle between successive fourth roots:

  Since we are interested in the fourth roots, we divide the angle θ by 4:

  θ/4 = (5π/6) / 4 = 5π/24

  This angle represents the angular distance between two successive fourth roots on the unit circle.

3. Calculate the distance between the two points:

  To find the distance, we multiply the angular distance by the radius of the unit circle (which is 1):

  Distance = (5π/24) * 1 = 5π/24

  Therefore, the distance between successive fourth roots of the complex number √3/2 - 1/2i on the unit circle is 5π/24 units.
