The one for 0 is -3
Answer:
A) 151 in³ or 151 cubic inches
Step-by-step explanation:
Volume of rocket = Volume of Cylinder + Volume of Cone
Step 1
Find the volume of the cylinder
Volume of a cylinder = πr²h
r = Diameter/2
= 5/2 = 2.5 inches
h = 6 inches
Hence,
π × 2.5² × 6
= 117.81 cubic inches
Step 2
Find the volume of the cone
Volume of a cone =1/3 πr²h
h = 11 inches - 6 inches
= 5 inches
r = 2.5 inches
Hence,
1/3 × π × 2.5² × 5
= 32.72 cubic inches
Therefore:
Volume of rocket = Volume of Cylinder + Volume of Cone
= 117.81 cubic inches + 32.72 cubic inches
= 150.53 cubic inches
Approximately to the nearest inch = 151 in³ or 151 cubic inches
Option A is correct
Okay so John needs to buy 7.6 quarts of paint so he would spend 26.55 on paint.
Hope this helps:)
Answer: see below
<u>Step-by-step explanation:</u>
C(x) = 39 when 0 < x ≤ 1.0
C(x) = 63 when 1.0 < x ≤ 2.0
C(x) = 87 when 2.0 < x ≤ 3.0
C(x) = 111 when 3.0 < x ≤ 4.0
C(x) = 135 when 4.0 < x ≤ 5.0
C(x) = 159 when 5.0 < x ≤ 6.0
Based on the information I provided above, the answers are:
a) x= 0.6, C(x) = 1.0
x = 1.0, C(x) = 39
x = 1.1, C(x) = 63
x = 2.5, C(x) = 87
x = 3.0, C(x) = 87
x = 4.8, C(x) = 135
x = 5.0, C(x) = 135
x = 5.3, C(x) = 159
b) If C(x) = 87, then 2.0 < x ≤ 3.0
c) Domain (all possible x-values): 0 < x ≤ 6.0
d) Range (all possible y-values): {39, 63, 87, 111, 135, 159}
