Answer:
All real numbers greater than -3
Step-by-step explanation:
The domain of a log is the baseline is greater than 0.
Set x + 3 greater than zero and solve
x + 3 > 0
x > -3
The only option that fits is E, because:
f(10)=4×10+10=50
A=1/2x Base x Height
= 1/2 (10)(24)
=120
A=90
B=53
The reason I am saying this is because you can see the 90 degree angle in A
Answer:
∠a=40°
Step-by-step explanation:
complement of angle a=90-a
supplement of angle a=180-a
90-a=1/2(180-a)-20
multiply by 2
180-2a=180-a-40
180-180+40=-a+2a
a=40
