Correct question is;
Tanya walked for 17 minutes from her home to a friend that lives 1.5 kilometers away. D(t) models Tanyas remaining distance to walk in kilometers, t minutes since she left home. What number type is more appropriate for the domain of d?
Answer:
0 ≤ t ≤ 17 ; (0, 17)
Step-by-step explanation:
We are told that she has walked for 17 minutes from her home to a friend that lives 1.5 kilometers away.
Now, we want to find the domain of numbers that shows her remaining distance.
Since she spent 17 minutes, then it means in modeling remaining distance it could be from 0 to 17 minutes as the case may be. Thus, the domain can be written as;
0 ≤ t ≤ 17 ; (0, 17)
Expression: 84 + 40
Here, Greatest Common Factor (GCF) of 84 & 40 is 4, so take it as a common factor:
= 4(21 + 10)
In short, Your Final Expression would be: 4(21 + 10)
Hope this helps!
Answer:
Yes, \sqrt{2}(\sqrt{3.5} + 2\sqrt{5} )
Step-by-step explanation:
By roots property, the roots can be re-write as multiplications or division, like this:
![\sqrt[n]{a} . \sqrt[n]{b} =\sqrt[n]{ab}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%20.%20%5Csqrt%5Bn%5D%7Bb%7D%20%3D%5Csqrt%5Bn%5D%7Bab%7D)
Here, we can re-write both roots:
and 
Now we have:
And we can take out the common expression:
⇒ Answer
Answer:
9) e=-40 10) k=9
Step-by-step explanation:
9) e/4-10=-20 add 10 on both sides
e/4=-10 Multiply everything by 4
e=-40
10) 0.4k-4+1.6k=14 combine like terms
2k-4=14 Add 4 on both sides
2k=18 divide both sides by 2
k=9
