The molecular diagram indicates a synthesis reaction.

A system in which one or more objects interacts and are converted to another different object or form. The resulting object is called product and the primary object are reactants.

The molecular diagram as shown in figure represent the chemical reaction between hydrogen gas and oxygen gas. Here reactants are 2-unit hydrogen gas and one-unit oxygen gas and resulting product is 2-unit water.

2H₂O (g) + O₂(g) ⇒ 2H₂O (g)

In this case, from 2 reactants we get a single product water as a gas, so the above chemical reaction is synthesis reaction.

According to the definition of synthesis reaction multiple reactants interacts for creating a single product.

generally, synthesis reaction is exothermic that means energy is released to the environment.

Step-by-step explanation:

To find the y-coordinate of point Q, we first need to find the coordinates of point Q. Since points P, Q, and R are collinear and the ratio of PQ to PR is 3/4, we know that the ratio of their x-coordinates and y-coordinates must also be 3/4.

Let's call the coordinates of point Q (x, y). We know that the x-coordinate of point Q is 3/4 of the way between the x-coordinates of points P and R. This means that the x-coordinate of point Q is (3/4) * (-4 - 3) + 3 = -1.

Similarly, the y-coordinate of point Q is (3/4) of the way between the y-coordinates of points P and R. This means that the y-coordinate of point Q is (3/4) * (5 - (-5)) - 5 = 0.

Therefore, the coordinates of point Q are (-1, 0). The y-coordinate of point Q is 0.

The coordinates of point Q are (3, -5), and the y-coordinate of point Q is -5.

Collinear points are points that lie on the same straight line. In other words, if you can draw a straight line through two or more points, then those points are said to be collinear.

Given that the ratio of PQ to PR is 3/4.

Let's assume the coordinates of point Q are (x, y).

Using the midpoint formula, we can find the coordinates of the midpoint M of line segment PR:

M = ((x1 + x2)/2, (y1 + y2)/2)

Substituting the coordinates of points P (3, -5) and R (-4, 5), we have:

M = ((3 - 4)/2, (-5 + 5)/2) = (-1/2, 0)

and, M = ((x + (-4))/2, (y + 5)/2)

Equating the x-coordinates and y-coordinates, we get:

-1/2 = (x - 4)/2 => x - 4 = -1 => x = 3

0 = (y + 5)/2 => y + 5 = 0 => y = -5

Therefore, the coordinates of point Q are (3, -5), and the y-coordinate of point Q is -5.

Given that organism A's population doubles every day for the first 5 days:

Therefore, an exponential expression to express organism A's population growth in the first 5 days is:

[tex]\boxed{y=a \cdot 2^5}[/tex]

Combine the increase and decrease in organism A's population after 8 days by multiplying the rates.  So the exponential expression for the total change in organism A's population after 8 days is:

Step-by-step explanation:

It is stared that the triangles are similar triangles.

Since they are similar triangles, we can find the length of the missing side using the ratio of similar sides.

DE/AB = EC/BC

[tex] \frac{6}{21} = \frac{2x + 3}{13x - 1.5} [/tex]

78x - 9 = 42x + 63

78x - 42x = 63 + 9

37x = 72

x = 2

now, replace x with 2 in the given expression for the length of BC:

13x - 1.5 = 13×2 - 1.5

|BC| = 24.5

Using mathematical operations, the recipe that consumes more sugar is the one for 3¹/₂ dozen cookies, which uses 3 cups.

The basic mathematical operations include addition, subtraction, division, and multiplication.

In this situation, we apply the division and multiplication operations to determine the number of cups of sugar required by the dozen cookies' recipe.

Rita's recipe for 3¹/₂ dozen cookies:

1 dozen = 12 units

The number of cookies = 42 (3¹/₂ x 12)

The number of cups of sugar = 3

Recipe for a dozen cookies:

The number of cookies = 12

The cups of sugar required = 0.86 cups (3/42 x 12)

Answer:

4

Step-by-step explanation:

For a triangle to exist:

A + B > C

B + C > A

A + C > B

We know already...

A = 13

B = 16

C = ?

Using the rules,

B + C > A

16 + C > 13

^ This won't tell us what C is because C would be 0 and obviously that wouldn't work for a triangle.

We'll try a different rule...

A + C > B

13 + C > 16

So, C would be 4. Because that's the smallest whole number that makes the equation true.

(Let's double check with all our rules to make sure it works for all of them)

A + B > C

13 + 16 > 4 <--True

B + C > A

16 + 4 > 13 <-- True

And we already did the last one, so we don't need to check that one.

So, C is equal to 4.

The required area of the lune is (D) √3/4 - π/24.

The measurement that expresses the size of a region on a flat or curved surface is termed area.

Surface refers to the area of a surface or the boundary of a tri structure, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

So,

The lune's area is equal to the smaller semicircle's area minus the segment's area.

The area of the segment is equal to the sum of the areas of the sector and the triangle formed by the intersection points and the larger semicircle's center.

Additionally, because all of the sides are one unit, the triangle thus constructed is an equilateral triangle.

Area of the lune = π * 1/8 (60/360 * π * 1² - √3/4 * 1²)

Area of the lune = π/8 - π/6 + √3/4

Answer:

The answer is 14.

Step-by-step explanation:

To solve this equation, we need to isolate the variable k on one side of the equation.

First, we can add 8k to both sides of the equation to get rid of the 8k term on the left side:

10 - 8k + 8k = -102 + 8k

This simplifies to:

10 = -102 + 8k

Then, we can add 102 to both sides of the equation to get rid of the -102 term on the right side:

10 + 102 = -102 + 8k + 102

This simplifies to:

112 = 8k

Finally, we can divide both sides of the equation by 8 to solve for k:

112/8 = 8k/8

This simplifies to:

14 = k

Therefore, the value of k that satisfies the equation is 14.

Answer:

f(x)=|x+4|-1 with a vertical stretch by a factor of 5, so the translation function becomes: 5|x + 4| - 5.

According to operations like multiplication or sum/subtraction either in its definition or in its domain, a translation is represented by a change in the function graph. Examples include shifting to the left or right or up or down, compressing or extending vertically or horizontally, and reflecting across the x- or y-axis.

For this problem, the function is given by:

f(x) = |x + 4| - 1.

For a vertical stretch by a factor of 5, the function is multiplied by 5, hence the translated function is given by:

Answer:

To solve this problem, you can set up an equation using the given information. Let "x" be the number in question.

We are told that 10 more than 32% of x is equal to 26. This can be written as:

10 + 0.32x = 26

To solve for x, you can start by subtracting 10 from both sides of the equation:

10 + 0.32x - 10 = 26 - 10

This simplifies to:

0.32x = 16

To isolate the x term, you can divide both sides of the equation by 0.32:

(0.32x)/0.32 = 16/0.32

This simplifies to:

x = 50

Therefore, the number we are trying to find is 50.

A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.

From the data set:

0, 4, 6, 11, 9, 8, 9, 1, 5, 9, 7

Mean = ( 0+ 4+ 6+11+ 9+ 8+ 9+ 1+ 5+ 9+7)/11 = 6.2

The mean is the middle number(s) in a data set. Hence
