Question: During which section was the person moving at the highest speed? What was their speed? Defend your answer
Answers
Answer:
C
Step-by-step explanation:
Speed is distance/time. We can solve for the highest speed by looking at each spot on the graph.
In a, the highest speed is 7/1, or 7. In b, it's 30/4, or 7.5. In c, it's 60/7, or about 8.57. In D, it's about the same, but since it's decreasing drastically, it will go to C.
Answer:
the person was moving the highest at C
since speed=gradient in distance time graphs so if you find each gradient c will be the highest being 30m/h while point A was 7.5m/h, b was stationery and point d was -20m/h, negative means it's decelerating. you could also guess that C has the highest speed since its the steepest line out of them all.

Triangle ABC with vertices A(–4, –4), B(–1, –2), C(3, –1) is rotated 180° about the origin. What are the coordinates of triangle A′B′C′?
Answers
Answer:
A(4, 4), B(1, 2), C(-3, 1)
Step-by-step explanation:
Because the triangle is rotated 180° about the origin you are just rotating it 2 quadrants, the size stays the same.
The rule for rotating 180° is if (x, y) is rotating 180° then the new position is (-x, -y).
So:
A(-4, -4), which then becomes B(-(-4), -(-4) ) = B(4, 4)
B(–1, –2) which becomes B(-(–1), –(-2) ) = B(1, 2)
C(3, –1) which becomes C(-3, –(-1) ) = C(-3, 1)
Solve for x to the nearest tenth.
Answers
Applying the Pythagorean Theorem, the value of x to the nearest tenth is: 4.5 units.
What is the Pythagorean Theorem?If c represents the length of the longest side (hypotenuse) of a right triangle, and a and b are the lengths of the other smaller legs of the right triangle, the Pythagorean Theorem states that:
c = √(a² + b²).
In the diagram given, we have a right triangle that is a part of the given shape. Where:
Hypotenuse = c = x
a = 4 units
b = 5 - 3 = 2 units
Plug in the values
x = √(4² + 2²)
x = √(16 + 4)
x = √20
x ≈ 4.5 units (nearest tenth)
Thus, applying the Pythagorean Theorem, the value of x to the nearest tenth is: 4.5 units.

What is surface area?It should be noted that the surface area of a solid object is a measure of the total area that the surface of the object occupies.
Length (l) = 5 in
Width (w) = 5 in

Write each equation in logarithmic form. 64=4³

The equation in logarithmic form is log₄(64) = 3

Convert the exponential equation to a logarithmic equation using the logarithm base (10)of the right side (0.01) equals the exponent (−2).

Answers
By using the principles of translation, the following equation can be derived for the graph of the translated text:
g(x) = |x + 2| + 1.
What is a translation?According to operations like multiplication or sum/subtraction either in its range (including values of y) or in its domain, a translation is represented by a change in the function graph (involving values of x).
Examples include shifts to the left, right, or bottom; compression or stretching along the vertical or horizontal axis; reflections across the x or y axes; and rotations of a degree measured around the origin.
From the graph, we have that the parent function was:
Shifted left 2 units, hence x -> x + 2.
Shifted up 1 unit, hence y -> y + 1.
Hence, considering the parent function f(x) = |x|, the equation for the translated graph is given by:
g(x) = |x + 2| + 1.

Micah is 7 years older than treasure. in 6 years the sum of their ages will be 51. how old is micah now?
Answers
The age of Micah is 23 years.
Let the age of treasure be x years. So, the present age of Micah will be (x + 7) years.
Now, age of treasure after 6 years = (x + 6) years
Age of Micah after 6 years = (x + 7 + 6) years
Age of Micah = (x + 13) years
As the question mentions, the sum of their ages is 51. So, relating the given information -
(x + 6) + (x + 13) = 51
Performing addition on Left Hand Side of the equation
2x + 19 = 51
Shifting 19 to Right Hand Side of the equation
2x = 51 - 19
Performing subtraction on Right Hand Side of the equation
2x = 32
Shifting 2 to Right Hand Side of the equation and performing division
x = 32 ÷ 2
x = 16 years
So, the present age of Micah = x + 7
Present age of Micah = 16 + 7
Present age of Micah = 23 years
Hence, the present age of Micah is 23 years.
