Answer: Heavily false. False by a long shot.
Step-by-step explanation: 1,000 kilometers is equivalent to 1e+9 millimeters. This is nine zeros after 1. So, this can be simplified as 1,000,000,000 milimeters, or rather, 1 billion millimeters. You can calculate this yourself by multiplying 1000 by 1,000,000 (1km = 1,000,000 mm.)

Answer:
x = 104°
Step-by-step explanation:
The 142° and <DCE form a straight line, and a straight line measures 180°, do the two angles add up to it:
180° = 142° + m<DCE
m<DCE = 38°
The red symbol in <DCE and <CDE mean they are congruent, so m<CDE is the same as m<DCE, which is 38°.
The 142° angle is an exterior angle to triangle, DCE, an exterior angles are the sum of the remote interior angles, which are <CDE and <DEC. Therefore, we can write:
142° = m<CDE + m<DEC
And we can substitute the values we have:
142° = 38° + x
x = 104°

A. To tailor to their training program.
B. To monitor development.
C. To send to college recruiters.
D. To analyze technique.
Answer:
C.) To send to college recruiters

The correct answer is C.) because this answer choice has nothing to do with assessing an athlete's performance. All of the other options involve assessing performance in some manner. An athelete's performance is directly tied to their training program, development, and technique.
A square has an area of 121 square centimetres.
What is its perimeter?
Answer:
44 cm
Step-by-step explanation:
The area of a square is the square of the side length. This means the side length is the square root of the area.
s = √A = √(121 cm²) = 11 cm
The perimeter of a square is the sum of its side lengths. There are 4 equal-length sides, so the perimeter is 4 times the length of one side:
P = 4s = 4(11 cm)
P = 44 cm
The perimeter of the square is 44 cm.
Answer:
44 cm
Step-by-step explanation:
Finding Side Length
Area = (Side length)²Take the square root on each sideSide length = √121Side length = 11 cmPerimeter
A square has 4 sidesTherefore, the perimeter is 4 times the side length4 × 1144 cmWrite 7.03 x 10-3 as an ordinary number
Answer: 0.00703
Step-by-step explanation: The ordinary number, or standard form, of this expression would be 0.00703 because here, we are multiplying 7.03 in scientific notation by a power of ten that is negative. If any exponential power of 10 is being multiplied and is negative, the digits move that same number of places to the right of the decimal point to render a smaller number than it was in the expression. Hope this helps!
2. Find the cosine function that is represented in the graph.
Answer:
[tex]f(x) = cos(x - \frac{\pi }{4} ) -1[/tex]
Step-by-step explanation:
In this graph, we have the coordinate point ([tex]\frac{\pi }{4} , 0[/tex]). Without translations, cos(0) = 0, which means that the graph is shifted to the right by [tex]\frac{\pi }{4}[/tex]. We also know that the graph is shifted down by 1 because we have the point
([tex]\frac{5\pi }{4} , -2[/tex]), but accounting for the right shift, this point should really by ([tex]\pi , -2[/tex]). cos([tex]\pi[/tex]) = -1, but on the graph it is -2, meaning that it is shifted down by 1.
Therefore, accounting for the right shift by [tex]\frac{\pi }{4}[/tex] and the shift down by 1, our equation is [tex]f(x) = cos(x - \frac{pi}{4} ) - 1[/tex].

How can you use the conversion rates of fluid ounces to cups, and cups to pints, to find the number of fluid ounces in a pint?
Answer:
multiply them
Step-by-step explanation:
Units work in algebraic equations the same way that variables do. They can be multiplied and divided as though they were variables.
For units conversion, we want to change the units without changing the value of the quantity. We do that by multiplying by a unit conversion factor that has a numerator equal to its denominator.
__
We know ...
1 cup = 8 fl oz
2 cups = 1 pint
These relations can be written as the conversion factors ...
(8 floz)/(1 cup) and (2 cups)/(1 pint)
Multiplying these together, the units of cups cancel, leaving fluid ounces per pint.
[tex]\dfrac{8\text{ fl oz}}{1\text{ cup}}\times\dfrac{2\text{ cup}}{1\text{ pint}}=\dfrac{8\cdot2\text{ fl oz$\cdot$cup}}{1\cdot1\text{ pint$\cdot$cup}}=\boxed{\dfrac{16\text{ fl oz}}{1\text{ pint}}}[/tex]

What is vertical stretch?In mathematics, a vertical stretch is a transformation of a function that changes the distance between the function's graph and the x-axis without changing its shape.
A vertical stretch multiplies all the y-coordinates of a function's graph by a constant factor greater than 1. This causes the graph to be stretched vertically and move further away from the x-axis.
For example, if we have a function f(x) = x^2, a vertical stretch by a factor of 3 would result in the function g(x) = 3x^2.
The graph of g(x) would be the same as that of f(x), but stretched vertically by a factor of 3.

Which statement is true for the equation 2x - 2x - 7 = -7?
O It has infinitely many solutions.
O It has two solutions.
O It has one solution.
It has no solution.
Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
2x-2x-7=-7
We need to solve it first as follows:
[tex]2x-2x-7=-7[/tex]
[tex]2x-2x=-7+7[/tex]
[tex]0=0[/tex]
Since L.H.S. = R.H.S.
So, it satisfies the equation for all x.
So, there will be infinitely many solutions.
Hence, Option 'a' is correct.

y = 2x − 5
y = -6x + 3
Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution.
Part B: Check your work. Verify your solution and show your work.
Part C: If the two equations are graphed, what does your solution mean?
Answer:
Part A
Solve by substitution.
Given equations:
y = 2x − 5y = -6x + 3⇒ 2x - 5 = -6x + 3
⇒ 2x - 5 + 5 = -6x + 3 + 5
⇒ 2x = -6x + 8
⇒ 2x + 6x = -6x + 8 + 6x
⇒ 8x = 8
⇒ 8x ÷ 8 = 8 ÷ 8
⇒ x = 1
To find y, substitute the found value of x into one of the equations:
⇒ y = 2(1) - 5
⇒ y = 2 - 5
⇒ y = -3
Therefore, the solution is (1, -3)
Part B
Substituting x = 1 into the equations:
y = 2x − 5
⇒ y = 2(1) − 5
⇒ y = 2 − 5
⇒ y = -3
y = -6x + 3
⇒ y = -6(1) + 3
⇒ y = -6 + 3
⇒ y = -3
When x = 1, both equations return a y-value of -3. Therefore, the solution is verified.
Part C
If the two equations are graphed, the solution will be the point of intersection.

Answer:
A) u=<9, 7>; v=<8, -2>
B) u+v = <17, 5>
C) 5u-2v = <29, 39>
Step-by-step explanation:
The component form of a 2-dimensional vector is usually written as an ordered pair with the horizontal component listed first. When vectors are added or subtracted, or multiplied by a scalar, the components are treated individually. Angle brackets may be used to signify the ordered pair represents a vector.
__
A.The horizontal and vertical dimensions of each of the vectors can be found by subtracting their coordinates, or by counting grid squares. Up or right is positive. The tail coordinates are subtracted from the head coordinates.
u = <11 -2, 1 -(-6)>
u = <9, 7>
v = <13 -5, 6 -8>
v = <8, -2>
__
B.The sum is the sum of the individual coordinates:
u +v = <9, 7> +<8, -2> = <9 +8, 7 -2>
u +v = <17, 5>
__
C.The weighted sum is the weighted sum of the individual coordinates:
5u -2v = 5<9, 7> -2<8, -2> = <5(9) -2(8), 5(7) -2(-2)>

Tell whether the angles are adjacent or vertical. Then find the value of x.
Answer:
The angles are vertical, and the value of x is 128 degrees
Step-by-step explanation:
You can tell vertical angles apart from adjacent by looking at their position. Adjacent angles are side by side, right next to each other. Vertical angles are directly across from each other, with their points touching.
Since the angle measures of vertical angles are equal, the value of x is 128
