For the function f(x) = −(x + 1)2 + 4, identify the vertex, domain, and range. The vertex is (−1, 4), the domain is all real numbers, and the range is y ≥ 4. The vertex is (−1, 4), the domain is all real numbers, and the range is y ≤ 4. The vertex is (1, 4), the domain is all real numbers, and the range is y ≥ 4. The vertex is (1, 4), the domain is all real numbers, and the range is y ≤ 4.

step-by-step explanation:

what? that isnt a question

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
