The announcer said, ingrid won the 100 metre race in 13.9 seconds. Her time was originally measured to 2 decimal places. What was the slowest time she could have run?
Answers
Answer:
13.94 seconds
Step-by-step explanation:
The greatest number with 2 decimal places that can be rounded to 13.9 is 13.94.
Answer: 13.94 seconds
The announcer said that Ingrid has won the race in 13.9 seconds, then the slowest time she could have run is 13.94 seconds.
What is approximation?Something similar to something else but not precisely the same is called an approximation. By rounding, a number can be roughly estimated.
By rounding the values in a computation before carrying out the procedures, an estimated result can be obtained.
13.94 is the largest number that can be rounded to the nearest two decimal places and be equal to 13.9.
Because after the second decimal, that is 4 the number has to increase as per the rules of approximation. That's why the number 13.94 up to two decimal places is correct.

The transformation that map line RS to line R"S" is " rotation of 180° about the origin, followed by a translation (x, y) → (x + 1, y + 1)" ⇒ B
Step-by-step explanation:
Let us revise some transformationIf the point (x, y) rotated about the origin by angle 180° counterclockwise, then its image is (-x, -y) ⇒ R(180, O) (x, y) → (-x, -y) If the point (x, y) translated horizontally to the right by h units then its image is (x + h, y) ⇒ T (x, y) → (x + h, y)If the point (x, y) translated vertically up by k units then its image is (x, y + k) ⇒ T (x, y) → (x, y + k)∵ The coordinates of the point R = (-2, 4)∵ The coordinates of point R" = (3, -3)→ Both coordinates in R" have opposite signs then R∴ R rotated 180° about the origin ⇒ using the 1st rule above∴ R' = (2, -4)→ Find the difference between the x-coordinate of R" and x-coordinate of R'∵ xR" - xR' = 3 - 2 = 1→ By using the 2nd rule above∴ R' translated 1 unit to the right → Find the difference between the y-coordinate of R" and y-coordinate of R'∵ yR" - yR' = -3 - (-4) = -3 + 4 = 1→ By using the 3rd rule above∴ R' translated 1 unit up∴ The rule of translation is T(x, y) ⇒ (x + 1, y + 1)Let us use these 2 rules on S to find S"∵ The coordinates of the point S = (-4, -1)∵ S is rotated 180° around the origin→ By using the 1st rule above, opposite the signs of its coordinates∴ S' = (4, 1)∵ S' translated 1 unit right→ By using the 2nd rule above, add its x-coordinate by 1∵ S' translated 1 unit up→ By using the 3rd rule above, add its y-coordinate by 1∴ S" = (4 + 1, 1 + 1)∴ S" = (5,2)→ That means the rules of transformation of point R is rightThe transformation that map line RS to line R"S" is " rotation of 180° about the origin, followed by a translation (x, y) → (x + 1, y + 1)"

Prove: The segment joining the midpoints of the diagonals of a trapezoid is parallel to the bases. Slopes are equal; therefore, segments are parallel
Answers
The segment joining the midpoints of the diagonals of a trapezoid is parallel to the bases
How to prove: The segment joining the midpoints of the diagonals of a trapezoid is parallel to the bases?From the figure, we have the following coordinates
B = (a, 0)
D = (d, c)
The midpoint of line segment BD is calculated as
BD = 1/2 * (x1 + x2, y1 + y2)
So, we have
BD = 1/2 * (a + d, 0 + c)
This gives
BD = ((a + d)/2, c/2)
Also, we have:
Lines MN and AB are horizontal lines
This means that they have a slope of 0
i.e.
Slope of AB = Slope of MN = 0
Parallel lines have equal slope
Hence, the segment joining the midpoints of the diagonals of a trapezoid is parallel to the bases

Can someone provide an example and counter example of a function ?
Answers
Answer:
A weekly salary is a function of the hourly pay rate and the number of hours worked
Step-by-step explanation:
a function is a map assigning values of a result or solution set to values of a set of initial or starting values.
we typically name these starting values x and the solution values f(x) or y (the results "created" out of x).
we often say
y = f(x)
and provide an expression or table to explain the logic of the mapping between x and f(x).
the only rule to be a function and not just a general relationship between these 2 sets :
every value in the set of starting values must have exactly one assigned solution value. not 0, not 2 (or more). one and only one.
but yes, different values of x can have the same assigned solution value. that is not a problem for a function. it just cannot be the other way around. there cannot be different solution values assigned to the same value of x.
so, a typical example of a function is a line.
e.g.
y = f(x) = 5x + 12
for every value of x you could think of (and everything else) there is exactly one result value calculated.
or the score board in a sports event :
athlete 1 : 12 points
athlete 2 : 24 points
athlete 3 : 20 points
athlete 4 : 22 points
...
the athletes are the "x". and their associated points the "f(x)" or "y".
no athlete is listed multiple times with different scores.
a typical example of not being a function is a circle. for almost every value of x inside the circle (that means for almost every point of the horizontal diameter of the circle) there are 2 values of y (that means points on the arc of the circle) : one above and one below the diameter.
or a strange score board like
athlete 1 : 12 points
athlete 2 : 24 points
athlete 3 : 20 points
athlete 2 : 22 points
athlete 4 : 22 points
...
athlete 2 is listed twice with 2 different scores.
so, this is therefore not a function.

Three bags of beads have masses of 10.3 grams 5.23 grams and 3.74 grams complete the bar diagram to find the total mass of all the beads
Answers
Therefore, the total mass of all bags of beads is 19.27 grams
Given masses of three bags of beads as
Mass of beads in bag1 = 10.3 grams
Mass of beads in bag2 = 5.23 grams
Mass of beads in bag3 = 3.74 grams
We have to calculate the total mass of all the beads as below
The total mass of all bags of beads = mass of bag1 + mass of bag2 + mass of bag3
= 10.3 + 5.23 + 3.74
= 19.27 grams

ind the equation of the line tangent to the graph of the given function at the point with the indicated x-coordinate.
f(x) = (x0.5 + 5)(x2 + x); x = 1
Answers
The equation of the line tangent to the curve is y = 19 · x - 7.
How to determine the equation of the line tangent to a curveIn this problem we need to find the equation of a line tangent to the function f(x) = (√x + 5) · (x² + x) for x = 1, that is, a line that only passes through one point of the entire curve. The equation of the line is introduced below:
y = m · x + b
Where:
m - Slopeb - InterceptThe slope of the line can be found by evaluating the first derivative of f(x) for x = 1:
f'(x) = (1 / 2√x) · (x² + x) + (√x + 5) · (2 · x + 1)
f'(1) = (1 / 2) · 2 + 6 · 3
f'(1) = 1 + 18
f'(1) = 19
The y-coordinate of the curve is:
f(1) = (√1 + 5) · (1² + 1)
f(1) = 6 · 2
f(1) = 12
Lastly, we determine the intercept of the tangent line:
b = y - m · x
b = 12 - 19 · 1
b = - 7
The equation of the line tangent to the curve is y = 19 · x - 7.

Answers
Answer:
The following are the correct choices
First : The equation c + d represents the sum of the two numbers
Third: The equation c = (1/2)d - 8 represents the relationship
and the last choice : The number c is 14
Step-by-step explanation:
Translate the word problem into equations and solve for c and d where c is the first number and d the second
Sum is 58 translates to
c + d = 58 (1) ===> First choice
First number is 8 less than half the second number translates to
c = (1/2)d - 8 (2) ==> Third choice
Multiply equation (2) by 2 on both sides giving
2c = d - 16 ==> 2c - d = -16 (3)
Add equations (1) and (3) giving
c + d + 2c - d = 58-16
3c = 42
c = 42/3 = 14 ===> Last choice
Substituting for c in equation (1) gives
14 + d = 58
d = 44

The area of the trapezoid is 42 square units
How to determine the areaThe formula for area of a trapezoid is expressed as;
Area = a + b/ 2 h
Where;
a is the length of the side = 6 unitsb is the length of its base = 8 unitsh is the height of the trapezoid = 6 unitsNow, to determine the area of the trapezoid, we need to substitute the values of the length of the side and its base with the height of the trapezoid.
Substitute the value into the equation
From the above information, we have that;
Area = 6 + 8/ 2 (6)
Find the quotient
Area = 14/ 2(6)
Area = 7(6)
Multiply through
Area = 42 square units
We have that the area of the trapezoid takes the value 42 square units

A ratio shows us the number of times a number contains another number. The area of the TV will be 729 inches².
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that the aspect ratio of the 36-inch tv is 16:9. Therefore, the width of the TV will be,
Length of the TV / Width of the TV = 16 : 9
36 inches / Width of the TV = 16 : 9
Width of the TV = 20.25 inches
Now, the area of the TV will be,
Area = Length of the TV × Width of the TV
