D) The domain of the function is all real numbers
Step-by-step explanation:
Answer:
g=3
Step-by-step explanation:
f(g)=g²+3g
Personally, I would do a guess and check to figure this out.
Let's try a number like 3. Insert it -
f(3)=3²+3(3) =9+9=18
Therefore, the answer is 3.
Answer:
m∠B =
.
Step-by-step explanation:
Since the three sides of the triangle are given, then we apply cosine rule.
=
+
- 2ac Cos B
But, a = 660 cm, b = 680 cm, and c = 100 cm.
So that;
=
+
-2(660 x 100) Cos B
462400 = 435600 + 10000 - 132000 Cos B
462400 = 445600 - 132000 Cos B
132000 Cos B = 445600 - 462400
= -16800
Cos B = 
= -0.1273
B =
-0.1273
= 
Thus, measure of ∠B is
.
Answer:
perimeter: 4x+2 area: x^2+x
Step-by-step explanation:
for perimeter, you add x+x+x+x+1+1, which is 4x+2
for area, you multiply x*x+1, which would be x^2+x
