Answer:
0.121 centimeters per second.
Step-by-step explanation:
We are told that in a recent snail race,the winning snail traveled 5.85 cm 3/4 of a minute.
To find the speed at which snail was traveling in centimeters per second, we will divide 5.85 by number of seconds in 3/4 of a minute.
First of all we will find how many seconds are equal to 3/4 of a minute.
Now we will divide 5.85 by 45 to find the speed of snail in centimeters per second.
Therefore, the snail was traveling at a speed of 0.121 centimeters per second.
Answer:
y- intercept = 
Step-by-step explanation:
Given
f(x) = 
To find the y- intercept let x = 0 , then
f(0) = 
[ 
= 1 ]
= × 1 = ← y- intercept
We can think of this as an equality
5 Lawns = 8 Hours
If she needs 40 hours, you can multiply 8 hours by 5 to get 40, but now it's not balanced. So, you need to multiply 5 to the other side too so:
5 x (5) = 8 x (5)
Therefore she mows 25 Lawns in 40 Hours
Answer:
30
Step-by-step explanation:
A triangle has a total degree of 180. We already have 150(from the 60 and the right angle) 180-150 is 30
For a radical with an
even root, like 2 in this case, if the radicand turns to a negative value, the result is just an imaginary value, which is another way to say, there's no such a root, no solution per se.
for that, let's first check when the radicand turns to 0 first.
so, that happens when x = 1, -8(1) +8, is just -8+8 or 0, ok.
so.. if "x" goes a bit higher, like say 2, -8(2) + 8 --> -16 + 8 --> -16
you'd get a negative value, and the radical doesn't have a root for that.
so... the domain, or values "x" can safely take without making the square root expression a negative value, are 1 or below, for example, if we use say -5
-8(-5) + 8 --> 40+8 --> 48 <------ a positive value
thus, (-∞, 1]
