Answer:
<h2>-2</h2>
Step-by-step explanation:
hello :
f(x)=-2x and g(x)=(1/2)^x
f(-2)=-2(-2) =4
g(-2)=(1/2)^-2 = 1/2^-2 = 2²=4
Answer:
x=Y/2−9/2
Step-by-step explanation:
please mark brainliest :)
Time taken by Michelle to complete the work alone = 6 hours
Time taken by Nancy to complete the work alone = 3 hours
Now, when they both are working on the same job for 1 hour,
Amount of job completed = (1/6) + (1/3)
= (1 + 2)/6
= 3/6
= 1/2
So in 1 hours time they both will complete half of the job. Then in 2 hours Michelle and Nancy will complete the total job. I hope the answer has come to your help.
Answer:
In our case the least precise is the one with no decimal units, in our case 231 cm
Step-by-step explanation:
Perimeter=2(L+w)
where;
L=length=81.47 cm
W=width=34.2 cm
Replacing;
Perimeter=2(81.47+34.2)=231.34 cm
The most precise is the one with the highest decimal units, for example 231.34 in our case the least precise is the one with no decimal units, in our case 231
