Answer:
I am pretty sure it is the first one
Step-by-step explanation:
Because it is (1, 6) on the graph
Sooooooo. . . ye!
(I'm sorry I couldn't explain more detailed)
The volume of a rectangular prism or cube is: Length × Width × Height
In this case,
- the length of the prism is 2 feet
- the width of the prism is 1.5 feet
- the height of the prism is 1.5 feet
Multiply the above to find the volume: 2 × 1.5 × 1.5 = 4.5 ft³
Keep in mind that volume is represented in cubic units!
Answer:
D.
Step-by-step explanation:
Area=w*h
w*h=(2h)*(h)=2h^2
dA/dt=2(2h)=4h
dA/dt=4h dh/dt in^2/sec
Answer:
Step-by-step explanation:
Given
Required
Plot a graph
First, we need to determine the minimum and maximum values of x and y
For x:
Minimum = 0
For maximum; Let y = 0
Solve for x
For y:
Minimum = 0
For maximum; Let x = 0
Solve for y

Answer:
The length of BC = 28 units
Step-by-step explanation:
* In triangle ABC
∵ Angles B and C are congruent
∴ m∠B = m∠C
* In any triangle if two angles are equal in measure, then the triangle is isosceles means the two sides which opposite to the congruent angles are equal in length
∴ AB = AC
∵ AB = 4x - 7
∵ AC = 2x + 7
∴ 4x - 7 = 2x + 7 ⇒ collect like terms
∴ 4x - 2x = 7 + 7
∴ 2x = 14 ⇒ divide both sides by 2
∴ x = 14 ÷ 2 = 7
* Now we can find the length of BC
∵ The length of BC = 4x ⇒ substitute the value of x
∴ The length of BC = 4 × 7 = 28 units
