Answer:
Total surface area is 630cm
Step-by-step explanation:
Surface area = (Perimeter of the base × Length) + (2 × Base Area) = (S1 +S2 + S3)L + bh
Answer:5
Step-by-step explanation:
If she ran around six times for one mile then if she ran around 1 time then that would be 1/6 of a mile so 5/6 of a mile would be 5 laps around
Answer
X=2+7/4y
Y=-8/7+4/7x
Answer:
A: (2,5)
B: (-4,-16)
C: (-2.5,-8.25)
Step-by-step explanation:
A. y = x²- 4x + 9
y = x² - 2(x)(2) + 2² - 2² + 9
y = (x - 2)² - 4 + 9
y = (x - 2)² + 5
Vertex: (2,5)
b. f(x) = x² + 8x
f(x) = x² + 2(x)(4) + 4² - 4²
f(x) = (x + 4)² - 16
Vertex: (-4,-16)
c. y = x² + 5x - 2
y = x² + 2(x)(2.5) + 2.5² - 2.5² - 2
y = (x + 2.5)² - 6.25 - 2
y = (x + 2.5)² - 8.25
