Answer:
C
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here (h, k) = (5, 2), thus
y = a(x - 5)² + 2
To find a substitute (4, - 3) into the equation
- 3 = a + 2 ⇒ a = - 3 - 2 = - 5
y = - 5(x - 5)² + 2 ← in vertex form
Expand (x - 5)² and distribute by - 5
y = - 5(x² - 10x + 25) + 2
= - 5x² + 50x - 125 + 2
= - 5x² + 50x - 123 ← in standard form
I'm assuming you're meaning 116.37 inches. 116.37 in = 9.6975 feet
Answer = 10 feet
100% + 3% = 103%
103% ÷ 100% = 1.03%
2000 x 1.03% squared = 2121.8

Answer:
750ft^3
Step-by-step explanation:
Given:
Volume of cone a=48ft^3
Radius of a=12 inches
Radius of b=30 inches
Volume of cone b=?
The linear state factor=ratio of the radio
=30/12
=2.5
Volume scale factors=linear state factor^3
=2.5^3
=15.625
Volume of Cone B= volume of Cone A × volume scale factor
=48 × 15.625
= 750 ft^3
