Hi there!
The answer to this question is: D
Step-by-step explanation:
The pattern is; up (red), down (blue), up (red)
so therefore the next pattern is down (blue) which is D
To find the next figure in the geometric pattern, analyze the given information and identify the pattern in the dot placements. Based on the description, each figure is obtained by adding dots in specific positions. The next figure can be determined by continuing this pattern.
Explanation:The next figure in the geometric pattern can be determined by analyzing the given information. Based on the description, we can infer that each figure is obtained by adding dots in a specific pattern. The third dot is located one and two-thirds perpendicular hash marks to the right of the center top perpendicular hash mark, while the fourth dot is in the same position as the Car X figure (one perpendicular hash mark above the center right perpendicular hash mark). To find the next figure, we need to continue this pattern by adding dots in the specified positions.

Reflexive property and transitive property.
The answer is option D.
What is Reflexive property?In algebra, the reflexive assets of equality state that a number is continually the same as itself. Reflexive belongings of equality. If a is various, then. a = a.
What is transitive property?In math, if A=B and B=C, then A=C. So, if A=5 for instance, then B and C should both also be five with the aid of the transitive property. That is actually—a foundational property of—math because numbers are constant and both facets of the equals signal need to be equal, by definition.

which number is prime ?
A : 8
B : 6
C : 13
D : 10
Answers
C : 13
8 is not a prime number since it's dividable by multiple numbers. For example 2(4), 1(8)
6 is not a prime number since it's dividable by 3(2), 1(6)
13 is a prime number because it's only dividable by itself.
10 is not a prime number because it can be divided by 5(2), 1(10)
So only 13 matches as a prime number.
Malcolm can run a race at a speed of 6 minutes per mile, while Joshua runs at 8 minutes per mile. In a 10-mile race, how many minutes after Malcolm crosses the finish line will Joshua cross the finish line if they start the race together?
Answers
Answer:
20 minExplanation:
The time to cross the finish line may be found using the speed vs. time equation:
speed = distance / timeFrom which you can solve for time:
time = distance / speed.Using the last equation, you can find the difference in the times for Malcolm and Joshua, but, since the speed must be expressed in miles per minutes, and the given data are minutes per mile, first you must convert the data.
Miles per minute is the inverse of minutes per mile, so the corresponding speeds are:
Malcolm's speed: 1 / (6 min/mile) = (1/6) miles/minJoshua's speed: 1 / (8 min/mile) = (1/8) miles/minTime for Malcom: 10 miles / [ 1/ (6 miles/min) ] = 10/(1/6) min = 60 minTime for Joshua: 10 miles / [ 1/ ( 8 miles/min) ] = 10/(1/8) min = 80 minDifference in times: 80 min - 60 min = 20 minHence, Joshua will cross the finish line 20 minutes after Malcolm crosses the finish line.

The perfect square of 3*4 is 9*16
Step-by-step explanation:
A perfect square is a number that can be expressed as the product of two equal integers.
For example 64 is a perfect square because if we multiply 8 two times we will get 64.
Thus the given expression is 3 * 4.
To find perfect square we square the numbers:
3² = 3*3 = 9
4² = 4*4 = 16
Thus the perfect square of 3*4 is 9*16 ....

Julio is visiting Bridal Veil Falls in Telluride Colorado. From the top of the 365 foot waterfall he looks down at an angle of depression of 27° and spots a bear fishing in the stream. To the nearest foot, how far is the bear from the base of the waterfall?
Answers
To find the distance from the bear to the base of the waterfall, we can use the tangent function, which relates the angle of depression to the distance. Using the given angle of depression of 27° and height of 365 feet, we can calculate that the bear is approximately 632 feet from the base of the waterfall.
Explanation:To find the distance from the bear to the base of the waterfall, we can use the tangent function, which relates the angle of depression to the distance.
In this case, we have an angle of depression of 27° and a height of 365 feet.
Let's denote the distance we're trying to find as x.
The tangent of the angle of depression is equal to the opposite side (365 feet) divided by the adjacent side (x).
So we can set up the equation tan(27°) = 365/x and solve for x.
Rearranging the equation, we have x = 365/tan(27°). Plugging in the values and using a calculator, we find that x is approximately 632 feet.
The bear is approximately 717 feet away from the base of the waterfall.
To find out how far the bear is from the base of the waterfall, use trigonometry, specifically the tangent of the angle of depression. Tangent relates the opposite side and the adjacent side in a right triangle.
1. Given Information:
- Height of the waterfall (opposite side), h = 365 feet.
- Angle of depression, [tex]\( \theta = 27\textdegree[/tex].
2. Formulate the Tangent Function:
The tangent of an angle in a right triangle is given by [tex]\( \tan(\theta) = \frac{\text{opposite}}{\text{adjacent}} \)[/tex].
So in our case, [tex]\( \tan(27\textdegree) = \frac{365}{d} \)[/tex].
3. Solving for d (the distance from the base of the waterfall to the bear):
Rearranging for d:
[tex]\[ d = \frac{365}{\tan(27\textdegree)} \][/tex]
4. Calculate the Value:
Using a calculator to find [tex]tan(27\textdegree)[/tex] which is approximately 0.5095.
[tex]\[ d = \frac{365}{0.5095} \approx 716.5 \text{ feet} \][/tex]
5. Round to the Nearest Foot:
[tex]\[ d \approx 717 \text{ feet} \][/tex]
So, the distance between the bear and base of the waterfall is approximately 717 feet.
Solve the equation. 9+ m/5 =19
Answers
Answer:
m = 50
Step-by-step explanation:
Simplify:
9 + m/5 = 19
9 + 1/5m = 19
1/5m + 9 = 19
Subtract 9 from both sides:
1/5m + 9 - 9 = 19 - 9
1/5m = 10
Multiply both sides by 5:
5 ⋅ ( 1/5m ) = ( 5 ) ⋅ (10)

Replace y with f(x).
f(x)=-3x+4
Answer:
[tex]f(x)=-3x+4[/tex]
Step-by-step explanation:
the function represented by [tex]9x + 3y = 12[/tex]
To write the given equation in f(x), we need to solve for y
Lets solve the given equation for y
[tex]9x + 3y = 12[/tex]
Subtract 9x from both sides
[tex]3y =-9x+12[/tex]
Now divide whole equation by 3, divide each term by 3
[tex]y =-3x+4[/tex]
To write it as a function , finally we replace y with f(x)
[tex]f(x)=-3x+4[/tex]

what is the y intercept of the line given by the equation below? y=4x-3
Answers
Answer:
y-intercept of y=4x-3 is -3
Step-by-step explanation:
The given equation is:
y = 4x -3
The equation is in slope-intercept form.
The standard equation of slope-intercept form is:
y = mx + b
where m is the slope and b is the y-intercept
So, comparing the given equation with the standard equation the y-intercept is -3
y-intercept of y=4x-3 is -3
Answer:
Step-by-step explanation:
The y intercept of any equation that is a function is the y value taken on when x = 0
So in this case it is y = - 3 because 4*0 = 0. All that is left for y is y = -3.
The point of interception is (0.-3). The way to confirm many answers is to graph the point.

The diagram below shows a square inside a regular octagon. The apothem is of the octagon is 13.28 units. To the nearest square unit, what is the area of the shaded region?
Answers
Answer:
I found the image of this problem. Its side measure is 13. The octagon can form 8 triangles. Its apothem can serve as the height of the triangle. We need to get the area of the triangle and multiply it by 8. We then deduct the area of the square from the total area.
Area of a triangle = (height * base) / 2
A = (15.69 * 13) / 2
A = 203.97 / 2
A = 101.985 sq. units
101.985 x 8 = 815.88 sq. units
Area of the square = s²
A = 13²
A = 169 sq. unit
Area of the shaded region: 815.88 sq. unit - 169 sq. unit = 646.88 sq. unit
