Answer:
-2×h
Step-by-step explanation:
because it drops-2 by hour so multiply-2 by the difference of hours
When applying indirect proofs, we assume the negation of the conclusion is true, and show that this assumption would lead to nonsense, or contradiction.
In our case we assume a is not smaller than 7, that is we assume a≥7.
a≥7 then, multiplying both sides by 3:
3a≥21, then, adding both sides 7:
3a+7≥28,
which is a contradiction because 3a+7 is smaller than 28.
So our assumption is wrong, which means the opposite of it is correct.
Answer: assume a≥7
Answer:
A. Domain=an area of territory owned or controlled by a ruler or government.
B. Range=the area of variation between upper and lower limits on a particular scale.
C. Relation=the way in which two or more concepts, objects, or people are connected; a thing's effect on or relevance to another.
D. Function=an activity or purpose natural to or intended for a person or thing.
never mind sorry didn't know this was math just delete the answer
The cube with 1 face with area 36 ft^2 has an edge of 6 ft.
The other cube has edges 2 * 6 = 12 ft long and its volume is 12^3
= 1728 ft^3 (answer).
Based on the circles shown in the diagram attached above, the line segments that must have the same length as segment AB are:
- Segment BC.
- Segment CD.
<h3>What is a circle?</h3>
A circle can be defined as a closed, two-dimensional curved geometric shape with no edges or corners. Also, a circle refers to the set of all points in a plane that are located at a fixed distance (radius) from a fixed point (central axis).
<h3>The equation of a circle.</h3>
Mathematically, the standard form of the equation of a circle is given by;
(x - h)² + (y - k)² = r²
Where:
- h and k represents the coordinates at the center.
- r represents the radius of a circle.
<h3>What is a line segment?</h3>
A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.
Based on the circles shown in the diagram attached above, the line segments that must have the same length as segment AB are:
- Segment BC.
- Segment CD.
