Answer:
23.59 - 14.89 = x
x = 8.7
Step-by-step explanation:
To find x, you need to add all of the other sides and subtract it from the perimeter. 5.62 + 5.62 + 3.65 = 14.89.
23.59 - 14.89 = x, so x = 8.7
Answer:
8.7
Step-by-step explanation:
Add all the numbers together (5.62, 5.62, and 3.65) then take away from the result (23.59) to get answer.

Step-by-step explanation:
A. -101 +37i
B.-11-107/
C. -11 +37/
D. -101-107/
To find the product of two complex numbers, you can use the distributive property. First, multiply the real parts and then multiply the imaginary parts. The correct answer is A. -101 + 37i.
To find the product of two complex numbers, you can use the distributive property. First, multiply the real parts of the complex numbers together, and then multiply the imaginary parts together. For the given complex numbers (8 + 5) and (-7 + 9):
Real part: (8 * -7) + (8 * 9) = -56 + 72 = 16
Imaginary part: (5 * -7) + (5 * 9) = -35 + 45 = 10
So, the product is 16 + 10i. Therefore, the correct answer is A. -101 + 37i.
Answer:
Therefore the radius of the can is 1.71 cm and height of the can is 2.72 cm.
Step-by-step explanation:
Given that, the volume of cylindrical can with out top is 25 cm³.
Consider the height of the can be h and radius be r.
The volume of the can is V=
According to the problem,
The surface area of the base of the can is =
The metal for the bottom will cost $2.00 per cm²
The metal cost for the base is =$(2.00× )
The lateral surface area of the can is =
The metal for the side will cost $1.25 per cm²
The metal cost for the base is =$(1.25× )
Total cost of metal is C= 2.00 +
Putting
Differentiating with respect to r
Again differentiating with respect to r
To find the minimize cost, we set C'=0
⇒r=1.71
Now,
When r=1.71 cm, the metal cost will be minimum.
Therefore,
⇒h=2.72 cm
Therefore the radius of the can is 1.71 cm and height of the can is 2.72 cm.
C. Let D= -3. Create a sign chart to solve ()≥0 with this value for D. Write your solution in interval notation. Solutions without sign charts will receive a score of zero.
