All the segments that are parallel to GH in the given shape are, BC, AD and FI. Option A
How to identify all segments parallel to GH
To identify all segments parallel to GH, understand the basic structure of a cuboid and its faces.
A cuboid is a three-dimensional shape with six rectangular faces. Each face of the cuboid is parallel to the opposite face. This property allows us to identify segments that are parallel to each other within the cuboid.
To identify segments parallel to a specific segment in a cuboid, follow these steps:
Understand the orientation of the cuboid:
Visualize the cuboid and identify its three pairs of opposite faces. These faces are parallel to each other.
Identify the given segment:
Determine the specific segment in the cuboid to which you want to find parallel segments.
In this case GH
Locate the faces that contain the given segment:
Identify the faces that contain the given segment. These faces will be parallel to each other.
Based on the highlighted steps above, by visualization,
Segment BC is parallel to GH
Segment AD is parallel to GH
Segment FI is parallel to GH
Therefore, all the segments that are parallel to GH are, BC, AD and FI. Option A

What is the length of AC on the number line
Answers
According to the given question, the length of AC on the number line is 5 units
The length of AC on the number line can be determined by subtracting the coordinate of point A from the coordinate of point C. Let's say point A is located at coordinate 2 and point C is located at coordinate 7. To find the length of AC, we subtract the coordinate of A from the coordinate of C: 7 - 2 = 5
Therefore, the length of AC on the number line is 5 units. Another way to think about this is by considering the distance between the two points. In this case, the distance between point A and point C is the same as the length of AC. If you have any further questions, please, let me know.

O B. False
Answers
The statement about the range of the logarithmic function F(x) = log_bx being positive real numbers is false; the range includes all real numbers.
The statement that the range of F(x) = logbx is the set of all positive real numbers is False. The range of a logarithmic function like F(x) = logbx, where b is the base and x is the argument, is actually all real numbers, not just the positive ones. This is because you can take the log of any positive number, but the result can be any real number, negative, positive, or zero (when x=1).
For example, if the base b is greater than 1, as x approaches zero from the positive side, logbx will approach negative infinity, illustrating how the range includes negative numbers.

Suponiendo que el movimiento de un cuerpo se interpreta según la ecuación:
Y=3t²-2 determina la velocidad media considerando los 5 primeros segundos de caida
Answers
Answer:
Average speed = 15
Step-by-step explanation:
To find the speed of the body, we can take the position equation and take the derivative in relation to time:
Speed = dY/dt = 2*3*t = 6t
Then, we need to find the speed at t=0 and the speed at t=5:
Speed(t=0) = 6*0 = 0
Speed(t=5) = 6*5 = 30
Now, we just need to make the average of both speeds:
Average = (0 + 30) / 2 = 15

[PLEASE HELP] The area of Bethany's garden will be 48 square feet once she expands it. She is not going to change the measurement on one side, but the other side will be 8 feet longer than before. The equation that models this situation and can be used to determine the possible dimensions of Bethany's garden is x^2 +8x -48. Factor to determine the possible dimensions of Bethany's new garden.
Answers
Final answer:
To find Bethany's expanded garden dimensions, we factored the quadratic equation x² + 8x - 48 = 0 to find that the original dimension is 4 feet, resulting in the new dimensions of 4 feet by 12 feet.
Explanation:
The student is tasked with finding the possible dimensions of Bethany's expanded garden, which will have an area of 48 square feet. The side lengths of the new garden are related by the fact that one side will be 8 feet longer than the other. We can use the given quadratic equation x² + 8x - 48 = 0 to model this situation.
Step-by-Step Factoring
First, we identify the coefficients in the equation, which are A=1 (coefficient of x²), B=8 (coefficient of x), and C=-48 (constant term).
To factor the quadratic equation, we look for two numbers whose product is A*C (-48) and whose sum is B (8). These numbers are 12 and -4.
Rewrite the middle term (8x) using the numbers found: x² + 12x - 4x - 48 = 0.
Factor by grouping: (x² + 12x) - (4x + 48) = 0 becomes x(x + 12) - 4(x + 12) = 0.
Factor out the common factor: (x - 4)(x + 12) = 0.
Solve for x: x = 4 or x = -12. Since a garden's dimensions must be positive, we disregard the negative solution. This leaves us with x = 4 feet as the original dimension and x + 8 = 12 feet as the expanded dimension.
Thus, the dimensions of Bethany's new garden are 4 feet by 12 feet.

a. Surya is competing in a triathlon that includes swimming, bicycling and running. For the first two segments of the race, Surya swam at an average rate of 4 kilometers per hour and bicycled at an average rate of 40 kilometers per hour. It took 81.75 minutes for Surya to swim and cycle a combined total of 43.29 kilometers, completing the first two segments of the race. How long, in minutes, did it take him to complete the swimming portion of the race? Express your answer to the nearest hundredth.
b. If an athlete who completes this triathlon swims, bicycles and runs a combined total of 52.95 kilometers, the distance the athlete swam is what percent of the total race distance? Express your answer as a percent to the nearest hundredth.
c. At what average rate, in kilometers per hour, must Surya run the third, and final, portion of the race if he wishes to complete the entire race in no more than 140 minutes? Express your answer to the nearest hundredth.
Answers
a) 18.68 minutes
b) 2.34%
c) 9.96 km/h
Step-by-step explanation:
a)
The velocity of Surya in the 1st segment (swimming part) is
[tex]v_1=4 km/h[/tex]
So, the distance covered by Surya in the swimming part is
[tex]d_1=4t_1[/tex]
where [tex]t_1[/tex] is the time taken to cover this part.
The velocity of Surya in the 2nd segment (biking part) is
[tex]v_2=40 km/h[/tex]
So the distance covered in the biking part is
[tex]d_2=40t_2[/tex]
where [tex]t_2[/tex] is the time taken to cover this part.
We know that the total distance covered in these 2 segments is
[tex]d=d_1+d_2=43.29[/tex]
So it can be rewritten as
[tex]4t1+40t_2=43.29[/tex] (1)
The total time taken to cover these two parts is
[tex]t=t_1+t_2=81.75 min =1.36 h[/tex]
So we have
[tex]t_2=1.36-t_1[/tex]
And substituting in (1) we can find t1:
[tex]4t_1 + 40(1.36-t_1)=43.29\\36t_1=11.21\\t_1=\frac{11.21}{36}=0.31 h = 18.68 min[/tex]
b)
The total distance covered in all 3 segments is
[tex]d=d_1+d_2+d_3=52.95 km[/tex]
where
where
d1 is the length of the swimming part
d2 is the length of the biking part
d3 is the length of the running part
We know that the distance covered in part 1 (swimming part) is
[tex]d_1=v_1 t_1 = (4)(0.31)=1.24 km[/tex]
Therefore we can find the percent that the swimming part correspond to the total race as:
[tex]\frac{d_1}{d}=\frac{1.24}{52.95}=0.0234 = 2.34\%[/tex]
c)
Here the total time taken by Surya for the race must be
[tex]t=140 min = 2.33 h[/tex]
And this is the sum of the times of the 3 segments:
[tex]t=t_1+t_2+t_3[/tex]
where
t1 is the time taken to complete the swimming part
t2 is the time taken to complete the biking part
t3 is the time taken to complete the running part
We know already that
[tex]t_1=0.31 h[/tex]
and
[tex]t_2=1.36-t_1=1.36-0.31=1.05 h[/tex]
So the time for the 3rd section must be
[tex]t_3=t-t_1-t_2=2.33-0.31-1.05=0.97h[/tex]
The distance to cover in the last part is
[tex]d_3=d-d_1-d_2=52.95-43.29=9.66 km[/tex]
So the average velocity of the last segment must be:
[tex]v_3=\frac{d_3}{t_3}=\frac{9.66}{0.97}=9.96 km/h[/tex]

Answers
10 blue marbles/25 total marbles
10/25=2/5 probability
The probability of choosing a blue marble is 2/5 or 0.4.
It is given that the jar contains 3 red marbles, 10 blue marbles, 8 green marbles, and 4 yellow marbles.
It is required to find the probability of choosing a blue marble.
What is probability?
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We have:
Number of total marbles = 3+10+8+4 ⇒25
Number of blue marble = 10
From the definition of the probability:
[tex]\rm Probability = \frac{Favourable \ outcomes}{Total \ outcomes}[/tex]
[tex]\rm Probability = \frac{10}{25}[/tex]
[tex]\rm Probability = \frac{2}{5 } \Rightarrow 0.4[/tex]
Thus, the probability of choosing a blue marble is 2/5 or 0.4.

Find the unit vector e which is collinear to vector a = (6,8) , and has the same direction.
Answers
the unit vector e which is collinear to vector a = (6,8) , and has the same direction is [tex]e=(\frac{3}{5} ,\frac{4}{5})[/tex] .
Step-by-step explanation:
Here we have , vector a = (6,8) . We need to find the unit vector e which is collinear to vector a = (6,8) , and has the same direction. Let's find out:
We know that for a vector [tex]a = (x,y)[/tex] the unit vector is given by :
⇒ [tex](\frac{x}{|a|} ,\frac{y}{|a|} )[/tex] , where |a| is modulus of vector a . So , Modulus of vector a is :
⇒ [tex]|a| = \sqrt{x^2+y^2}[/tex]
⇒ [tex]|a| = \sqrt{6^2+8^2}[/tex]
⇒ [tex]|a| = \sqrt{36+64}[/tex]
⇒ [tex]|a| = \sqrt{100}[/tex]
⇒ [tex]|a| =10[/tex]
Hence , unit vector is given by [tex](\frac{6}{10} ,\frac{8}{10})[/tex] or , [tex](\frac{3}{5} ,\frac{4}{5})[/tex] . Vector is already collinear as it's in same direction of original vector as :
⇒ [tex]e=(\frac{3}{5} ,\frac{4}{5})[/tex]
Therefore , the unit vector e which is collinear to vector a = (6,8) , and has the same direction is [tex]e=(\frac{3}{5} ,\frac{4}{5})[/tex] .

What is the Triangle Sum Theorem?According to the triangle sum theory, all the interior angles of a triangle will add up to 180 degrees.
Given:
m∠A = 65°
m∠B = (3x - 10)°
m∠C = (2x)°
Therefore:
65 + 3x - 10 + 2x = 180

The area of a trapezium is 31.3cm if the parallel sides are of length 7.3cm and 5.3cm, calculate the perpendicular distance between them
Answers
Answer:
4.968 cm
Step-by-step explanation:
Given area of prism = 31.3 cm
This problem can be solved by using formula to calculate area of trapezium which is given below
Formula to calculate area of prism =( sum of parallel sides * perpendicular distance between parallel side )/2
let the perpendicular distance between parallel side = X
sum of parallel sides = 7.3+5.3 = 12.6 cm
Therefore by using formula
31.3 = (7.3+5.3)*X/2
=> 31.3 * 2 = 12.6*X
=> X = 62.6/12.6 = 4.968
Hence perpendicular distance between parallel side is 4.968 cm
