It's easy my friend the answer is 224.7 Tada! Your answer
Answer:
C
Step-by-step explanation:
40 minutes every day for a week is 40 multiplied by 7, which is 280. Dividing that by 60 is 4 remainder 40, so 4 hours and 40 minutes.
The piecewise function is basically the result of two different functions combined together. If x is 0 or larger, then h(x) = x+4. Otherwise, if x < 0, then h(x) = -x-4
No matter what number you pick for x, the h(x) function will be used in some way. So the domain is the set of all real numbers. To write this in interval notation, we write which means we start off at negative infinity and go to positive infinity. This is basically saying "the entire real number line". Since we can't actually reach either infinity, we always use parenthesis with them. <u>Never</u> use square brackets with either infinity
From the graph (see attached image below), we see that (0,-4) is the lowest point. This means y = -4 is the smallest y output possible, though we can't actually reach it because of the open circle at (0,-4). We can get any other larger y value. So the range is therefore: meaning we start at -4 and head off to positive infinity. The curve parenthesis next to -4 the reader "exclude -4 as part of the range". There is an open hole or gap here. Another way to state the range is to write y > -4
Answer:
angle a = 20 degrees
angle b = 160 degrees
angle c = 15 degrees
angle d = 75 degrees
Step-by-step explanation:
Every straight angle equals 180 degrees, and every right angle is half of that (90 degrees). This is helpful to remember during geometry- every unknown angle is part of either a right or a straight angle. Honestly, if you look carefully enough, most of the answers are supplied in opposite angles.
Hope this helps! If not, let me know! :)
Answer:
6x = 3/8x + 4
Step-by-step explanation:
The product of a number (x) and 6 ... 6x
is ... =
four more than ... ___ +4
the product of the number and 3/8 ... 3/8x . . . . (goes in the blank that is added to 4).
Thus, this statement is directly translated to ...
... 6x = 3/8x + 4
