Answer:
Dog: 3 meters per second
Cat: 4 meters per second
Step-by-step explanation:
It is given that they are running from a corner around a rectangular garden, the dog runs west and the cat runs north, after 2 seconds the distance between them is 10 meters.
This forms a right triangle, the hypotenuse being 10.
So using the Pythagorean theorem we know that:
a^2 (dog's distance traveled after 2 seconds) + b^2 (cat's distance traveled after 2 seconds) = c^2 (10^2=100)
So now we can use trial and error, therefore figuring out the measurements of the two sides of the right triangle are 6 and 8. We know that this is the distance traveled after 2 seconds so we divide both integers by 2 and get 3 and 4.
So, the dog travels 3 meters per second and the cat travels 4 meters per second.
Their speed in m/s is 3 m/s for dog and 4 m/s for cat.
What is Speed?This is defined as the magnitude of the rate of change of its position with time.
We were told that they ran ran from a corner around a rectangular garden, the dog runs west and the cat runs north and after 2 seconds the distance between them is 10 meters.
This depicts a right triangle where the hypotenuse being 10.
Pythagorean theorem = a² + b² = c²
= a² + b² = 100
We can deduce that the measurements of the two sides of the right triangle are 6 and 8. Since it is the distance traveled after 2 seconds, we divide both integers by 2 and get 3 and 4.
Therefore, the dog travels 3 m/s and the cat travels 4m/s.

Answer:
11. 78
12. 4x² - 3x - 1
Step-by-step explanation:
11. Sum of n whole numbers = ½(n² + n)
Multiply
½*n² + ½*n
= n²/2 + n/2
To find the sum of the first 12 whole number, substitute 12 for n into the equation.
= 12²/2 + 12/2
= 144/2 + 12/2
= 72 + 6
= 78
12. Area of trapezoid = ½(a + b)*h
Where,
a = 5x - 4
b = 3x + 2
h = x + 1
Area = ½(5x - 4 + 3x + 2)*(x + 1)
Area = ½(8x - 2)*(x + 1)
Area = ½[8x(x + 1) -2(x + 1)]
= ½[8x² + 8x - 2x - 2]
Add like terms
= ½(8x² - 6x - 2)
= ½(8x²) - ½(6x) - ½(2)
= 4x² - 3x - 1

This circle is centered at the origin, and the length of its radius is 2. What iS
the circle's equation?
Answer:
Step-by-step explanation:
If the center of the circle is at the origin, the general formula for the circle is
x^2 + y^2 = r^2.
Since r = 2 units in this particular problem, the equation of the circle is:
x^2 + y^2 = 2^2, or x^2 + y^2 = 4

FIND THE ERROR: Chun and Traci are determining the value of x in the figure. Chun says to find the value of x, solve the proportion = 1, but
Treci says to find the value of 1, the proportion is should be solved. Is either of them correct? Explain your reasoning
9514 1404 393
Answer:
Chun is correct
Step-by-step explanation:
The angle bisector divides the sides of the triangle proportionally. Any proportion that is written should equate ratios of corresponding sides.
Chun's proportion correctly relates the top-side measures to their corresponding bottom-side measures:
top short : bottom short = top long : bottom long
5 / 8 = 15 / x
__
Traci's error is that she mixes top-side and bottom-side measures. Her incorrect relation is ...
top short : bottom long = bottom short : top long
She has used top:bottom for short measures and bottom:top for long measures. This mixing will give Traci an incorrect solution.
__
Chun's proportion correctly gives x=24.
Answer:
Step-by-step explanation:
Chun; by the Triangle Angle Bisector Theorem, the correct proportion is 58=15x.
