Answer: What is the question?
Step-by-step explanation:
Answer:
75.06239187
Step-by-step explanation:
1/2bh= Area of a Triangle
6^2+b^2=8.5^2 because we are missing a side we need to use the pythagorean theorem.
36+b^2=72.25
b^2=36.25
b=6.02
6.02+19= base
25.02
Now area
1/2bh
1/2 (25.02*6)
25.02*6= 150.1247
150.1247/2= 75.06239187 is Area
The above decimals before area are rounded.
Answer:
A
Step-by-step explanation:
A function have the inverse only if it passes the horizontal line test ,
For the given options we need to look for the function which passes the horizontal line test
Option A is g(x)= 2x-3 which is a straight line with slope not equal to 0 so it passes the horizontal line test and hence it will have an inverse which is also a function.
Option B: we need to restrict the domain to get the inverse so the option B is not correct .
Option C : It also fails the horizontal line test .
Option D : Horizontal line so it also fails the horizontal line test .
<span>2(1+4n)+10(n-7)=2n-n
distribute
2+8n+10n-70=2n-n
combine like terms
18n-68=n
move n to other side
17n=68
divide
n=4</span>
