Step-by-step explanation:
By Pythagoras Theorem:
Answer:
B. Only (-3,5)
Step-by-step explanation:
1. Plug in the x values from the answer choices and see if it gives you the y-value in the answer choices.
A. y=-3(-2) - 4
= 6 - 4
y = 2
The ordered pair for answer A is (-2,4) where the y-value is 4. Well, when you plugged in -2 for x you got 2, not 4. So A can't be the right answer.
B. y=-3(-3) - 4
= 9- 4
y = 5
The y-value in this ordered pair (-3,5) is indeed 5, so this answer holds true.
Therefore, the answer is B because it is the only ordered pair that has the correct solution.
Answer:
It would be 1,080,000,000.
Step-by-step explanation:
When you round China's population, it would be 1,400,000,000. If you rounded USA's, it would be 320,000,000. Subtract them, and you get 1,080,000,000. Hope this helps.
Answer:
B. 20 sq. cm
Step-by-step explanation:
Given:
The legs of a right triangle measure:
and
To find the area of the triangle.
Solution:
The legs of the right triangle means the base and height of the triangle and thus, we can apply the formula to find the area of the triangle.
Plugging in base and height of the triangle in the formula.
Thus, area of triangle = 20 sq. cm.
The domain is the set of allowed x inputs, or x coordinates of a function. In this case, any point on the curve has an x coordinate that is 4 or smaller.
Therefore, the domain is the set of numbers x such that
To write this in interval notation, we would write This interval starts at negative infinity and stops at 4. We exclude infinity with the curved parenthesis and include 4 with the square bracket.
-----------------------------------------------------------------------
The range is the set of possible y outputs. Every point on this curve has a y coordinate that is either 0 or it is larger than 0.
The range is the set of y values such that
In interval notation, it would be written as This time we start at 0 (including this endpoint) and "stop" at infinity
note: we always use curved parenthesis at positive or negative infinity because we cannot reach either infinity
