Answer:
f(3) = -11
Step-by-step explanation:
f(3) means you sub the value that is inside into x
f(3) = -3(3) - 2
= -9 - 2
= -11
Answer:
1. A=42
L=14
42=W(14)
divide both sides by 14
3=W
2. A=96
L=12
96=W(12)
divide both sides by 12
8=W
3. A=90
L=18
90=W(18)
divide both sides by 18
5=W
4. A=1.50
L=15
1.50=W(15)
divide both sides by 15
0.1=W

Answer:
The number of cubes are needed to fill the rectangular prism = 448 cubes
Step-by-step explanation:
It is given that,
A rectangular prism has a length of 7 cm, a width of 4 cm, and a height of 2
cm. The prism is filled with cubes that have edge lengths of 1/2 cm
<u>To find the volume of rectangular prism</u>
Volume of rectangular prism = Length x Width X Height
Length = 7 cm, Width = 4 cm and height = 2cm
Volume = 7 x 4 x 2 = 56 cm³
<u>To find the volume of small cubes</u>
Volume of cube = a³
a = 1/2 cm = 0.5³ = 0.125
<u>To find the number of cubes needed to fill prism</u>
Number of cubes = Volume of prism/ volume of cube
= 56/0.125 = 448 cubes
Therefore the correct answer is 448 cubes
The answer is the first diagram (light blue color in the choices) where 2.9m is the hypotenuse or the longest length. The height of the altitude is 1.5 meter and it is perpendicular from the ground level. The angle opposite to 2.9m is 90°.
