Answer:
Step-by-step explanation:
Formula for area of a triangle:
Height x Base /2
Base (b) = h +4
Height = h
h + 4 x h /2 = 30cm
=> h +4 x h = 60
=> h+4h =60
=> 5h = 60
=> h = 12
Height = 12
Base = 12 +4 = 16
Answer:
No.
Step-by-step explanation:
According to the law of exponent:-

Therefore:-

Answer:
choose x ≥ 0 or x ≤ 0
Step-by-step explanation:
The vertex of the parabola is at x=0. If values of x are included from both sides of the vertex, the function will not pass the horizontal line test. So, the domain must be limited so that it does not include both positive and negative values of x.
The domain could be x ≥ 0, or x ≤ 0, or some subset of either of these intervals.
Answer:
g(x) approaches negative infinity
Step-by-step explanation:
g(x) = -x² + 2x + 4
limit at g(x) approaches infinity = -(∞)² + 2(∞) + 4 = -∞
I can't solve for f(x) because you didnt give me f(x)
Answer:
11/8 or, 1 and 3/8
Step-by-step explanation:
First, we have to make both the denominators the same. In this case, we can multiply 3/4 by 2, to make 4, the denominator, into 8. What we do to the denominator, we must do to the numerator! So, we multiply 3 by 2, and get 6!
Now we have, 5/8 + 6/8, which equals 11/8! Which can also be simplified to 1 and 3/8 (because the numerator is larger than the denominator)
Hope this helps! :)
