Answer:
The answer is (D) ⇒ AE ≅ CE
Step-by-step explanation:
∵ <em>ABCD is a parallelogram</em>
∴ AB = DC , AB // DC
∴ BC = AD , BC // AD
∴ m∠A = m∠C , m∠B = m∠D
∴ AC and BD bisect each other at E
∴ AE = CE
∴ The right statement is D ⇒ AE ≅ CE
Answer:A
Step-by-step explanation: due to the all being divisible by 4
Answer:
y = 2x +1
Step-by-step explanation:
y=kx+1
Substitute the point into the equation
3 = k(1) + 1
3 = k+1
Subtract 1 from each side
3-1 = k
2 = k
y = 2x +1
The slope is 2 and the y intercept is 1
Answer:
Range [-2,2]
Cosine value varies from -1 to 1, hence -2cos 3x can vary from +2 to -2. The range of the given function , in interval notation, would thus be [-2,2]. In set builder notation it can be expressed as
{y∈R∣−2≤y≤2 }
It most likely might be wrong though so sorry for that.
