No, your friend is not correct. A rhombus can have congruent diagonals. A rhombus is a parallelogram with four congruent sides.

The diagonals of a rhombus bisect each other at right angles. Thus, the diagonals of a rhombus can be congruent if they are equal to each other and intersect at right angles.A rectangle is also a parallelogram with four right angles. It has two pairs of congruent sides and its diagonals are equal to each other. So, a rhombus does not need to be a rectangle to have congruent diagonals. They are distinct shapes in Euclidean geometry. Thus, a rhombus may have congruent diagonals while being a rhombus and not a rectangle.More than 250

Answer:

y = 1/2 x - 6

Step-by-step explanation:

y = mx + b

y = (1/2)x + b

-4 = (1/2) × 4 + b

-4 = 2 + b

b = -6

y = 1/2 x - 6

The answer is:

\(\rm{y=\dfrac{1}{2} x-6}\)

Work/explanation:

Given the slope and a point on the line, we can write the equation in point slope form, which is:

\(\rm{y-y_1=m(x-x_1)}\)

Where m is the slope and (x₁, y₁).

Plug the data in the formula:

\(\rm{y-(-4)=\dfrac{1}{2}(x-4)}\)

Simplify:

\(\rm{y+4=\dfrac{1}{2} (x-4)}\)

Now focus on the right side & simplify it :

\(\rm{y+4=\dfrac{1}{2}x-2}\)

Finally, subtract 4 on each side:

\(\rm{y=\dfrac{1}{2} x-2-4}\)

Simplify:

\(\rm{y=\dfrac{1}{2} x-6}\)

This is our equation in slope intercept form.

The set A' UC is the set of all elements that are in A or C but not in both. In this case, the set A' UC is {5}.

To find the set A' UC, we can use the following steps:

Find the intersection of A and C. This is the set of all elements that are in both A and C. In this case, the intersection is {1, 2, 3}.

Subtract the intersection from U. This gives us the set of all elements that are in U but not in A or C. In this case, the set is {4, 5, 6, 7}.

Add the elements of A that are not in the intersection to the set from step 2. This gives us the set of all elements that are in A or C but not in both. In this case, the set is {5}.

It is important to note that the set A' UC is not the same as the union of A and C. The union of A and C is the set of all elements that are in A or C or both. In this case, the union of A and C is {1, 2, 3, 4, 5, 6, 7}.

If his beard  was 8 millimeter long and each passing week it grew 2 additional millimeters, the graph that represents the relationship between the length of his beard in millimeter and time in week has been plotted

The initial length of the beard = 8 millimeter

The length of beard grow in each week = 2 millimeter

Consider the number of week as x

Therefore the linear relationship will be

The length of the beard y = 2x + 8

Plot the graph using the equation

Hence, If his beard  was 8 millimeter long and each passing week it grew 2 additional millimeters, the graph that represents the relationship between the length of his beard in millimeter and time in week has been plotted

The equation of a line y=2x+8.

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in the value of y on the vertical axis/change in the value of x on the horizontal axis

Looking at the given line,

y = 2x + 7

Compared with the slope-intercept equation,

Slope, m = 2

If a line is parallel to another line, it means that both lines have equal or the same slope. This means that the slope of the line passing through the point (-2, 4) is 2

Substituting m= 2, y = 4 and x = -2 into the equation, y = mx + c , it becomes

4 = 2 × - 2 + c

4 = - 4 + c

c = 4 + 4 = 8

The equation becomes y=2x+8.

The simplified form of the trigonometric expression cscθ - cosθ cotθ is cscθ - 1.

To simplify the given expression, let's start by expressing each trigonometric function in terms of sine and cosine. The reciprocal of the sine function is the cosecant function (csc), and the reciprocal of the tangent function is the cotangent function (cot).

cscθ - cosθ cotθ can be written as cscθ - cosθ (cosθ/sinθ).

To simplify further, we can combine the terms with a common denominator. The common denominator is sinθ, so we need to multiply cscθ by sinθ to get a common denominator.

This gives us (1/sinθ)(sinθ) - cosθ (cosθ/sinθ).

Now, simplifying the expression, we have 1 - \(cos^2(Θ)/sinΘ.\)

Using the trigonometric identity sin^2θ + cos^2θ = 1, we can replace cos^2θ with 1 - sin^2θ.

Substituting, we get \(1 - (1 - sin^2θ)/sinθ.\)

Simplifying further, we have \(1 - 1/sinθ + sin^2θ/sinθ.\)

Finally, combining the terms, we get 1 - cscθ + sinθ.

Therefore, the simplified form of cscθ - cosθ cotθ is cscθ - 1.

triangle STU and WEK are CONGRUENT

ST=WK SIDE OF A CONGRUENT TRAINGLE ARE EQUAL

2M=N.....1

SU=WE

3M+5=N+8

NOW

TU=WK=N=6CM.

Since 24.8 minutes is less than 36.4 minutes, you would still meet your goal because your total running time added to your swimming and biking times is less than 100 minutes.

The inequality that represents how many minutes x you can take to finish the running event and still meet your goal is: 18.2 + 45.4 + x < 100. To solve for x, we need to isolate it on one side of the inequality:

18.2 + 45.4 + x < 100
x < 100 - 18.2 - 45.4
x < 36.4

Therefore, you can take no more than 36.4 minutes to finish the running event and still meet your goal of finishing with an overall time of less than 100 minutes.

For question 3, if it takes 8 minutes to run a mile and the running event is 3.1 miles long, it would take you 24.8 minutes to complete the running event. This time is less than the maximum time of 36.4 minutes that you can take to still meet your goal, so yes, this time would allow you to reach your goal.

For question 4, the statement is just reiterating the goal mentioned in the first sentence, that your overall time for all three events must be less than 100 minutes. It confirms that you have met your goal by stating that your total running time added to your swimming and biking times is less than 100 minutes.

There are 69300 possible ways of selecting six bottles randomly with two bottles of each variety.

Probability is a branch of mathematics concerned with numerical descriptions of how likely an event is to occur or how likely a statement is to be true. In the given question, we have to select 6 bottles randomly with two bottles of each variety,

= ¹⁰C₂× ⁸C₂ × ¹¹C₂

¹⁰C₂= [1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 × 9 × 10] / [(1 × 2)(1 × 2 × 3 × 4 × 5 × 6 × 7 × 8)]

= 90/2

= 45

Similarly,  ⁸C₂  = 28

In the same way ¹¹C₂= 55

= ¹⁰C₂× ⁸C₂× ¹¹C₂

= 45 × 28 × 55

= 69300

Therefore, there are 69300 possible ways of selecting 6 bottles with two bottles of each variety.

The maximum height of the function is 9

The equation of the function is given as:

n=-1t^2 + 2t + 8

Differentiate the function

n' = -2t + 2

Set to 0

-2t + 2 = 0

Subtract 2 from both sides

-2t = -2

Divide both sides by -2

t = 1

Substitute t = 1 in n=-1t^2 + 2t + 8

n=-1(1)^2 + 2(1) + 8

Evaluate

n=9

Answer:

5 hours

Step-by-step explanation:

the graph shows that the amount of snow on the ground did not change from the 6th hour to the 11th, 11-6=5

In the given situation snow stopped for 5 hours when the graph is constant.

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

If we observe the given graph where the y-axis represents the height of snow in inches and the x-axis represents the time in hours it snowed for.

The graphs stop increasing from x = 6 to x = 11 or remain constant.

∴ The snow stopped for (11 - 6) = 5 hours.
