Answer:
2 real roots
Step-by-step explanation:
If the discriminant is any positive number, that means the quadratic will have 2 real roots, or solutions.
Since the discriminant, 36, is a positive number, this will apply.
So, if the discriminant is 36, there will be 2 real roots.
4x = 14y
y = 4/14(x)
y = 2/7(x) slope = 2/7
<span>-2x+7y=14
7y = 2x + 14
y = 2/7(x) + 2 slope = 2/7
parallel lines, slope is the same
both lines have slopes equal 2/7

Answer: C
Step-by-step explanation:
450 is her initial value
225 is her rate of change or constant rate
Its 1/5,
35/100 - 15/100 = 20/100
for 20, 40, 60, 80, 100
1, 2, 3, 4, 5
so 20/100 = 1/5
Answer:
33.4933 ≈ 33.5 mm³
Step-by-step explanation:
Given that,
→ Radius (r) = 2 mm
Formula we use,
→ 4/3 πr³
Let's solve for the volume of sphere,
→ 4/3 πr³
→ 4/3 × 3.14 × 2 × 2 × 2
→ 4/3 × 3.14 × 8
→ 4/3 × 25.12
→ 100.48/3
→ 33.4933
→ [ ≈ 33.5 mm³ ]
Hence, volume of sphere is 33.5 mm³.
