Question 2 of 7 A hospital has a large fish - 1

Answers

Answer 1
Answer:

Answer:

332 ft²

Step-by-step explanation:

The total area of the fish tank is the sum of the areas of the base and the walls.

The area of a rectangle is A = side 1 × side 2

Base

A = 12 ft × 5 ft = 60 ft²

2 8×12-walls

A = 8 ft × 12 ft = 96 ft²

2 walls: 2 × 96 ft² = 192 ft²

2 5×8-walls

A = 5 ft × 8 ft = 40 ft²

2 walls: 2 × 40 ft² = 80 ft²

Total area: 60 ft² + 192 ft² + 80 ft² = 332 ft²
Answer 2
Answer: 2 times 8 x 12

192

2 times 5 x 8

80

2 times 12 x 5

60

192+80+60=332 ft^2

Find f(–2) for the function f(x) = 3x2 – 2x + 7. −13 −1 1 23

Answers

Answer:

The correct option is 4. The value of f(-2) is 23.

Step-by-step explanation:

The given function is

f(x)=3x^2-2x+7

We have to find the value of f(-2). It means we need to find the value of function f(x) at x=-2.

Substitute x=-2 in the given function to find the value of f(-2).

f(-2)=3(-2)^2-2(-2)+7

On simplification we get

f(-2)=3(4)-(-4)+7

f(-2)=12+4+7

f(-2)=23

The value of f(-2) is 23. Therefore the correct option is 4.

Answer:

f(-2) = 23

Step-by-step explanation:

f(x)=3x^2-2x+7\n\nf(-2)\to\text{put x = -2 to the equation of a function:}\n\nf(-2)=3(-2)^2-2(-2)+7=3(4)+4+7=12+4+7=23

Can someone help me on B and C

Answers

B. If you look at the graph and go over 5cm and up 3m, you can see that that point is not near the others, so it can't be accurate according to the data on your graph.C. If you go over 3.2 cm on your graph, go up to where the other points are, and you will see that the most likely height would be about 4.7m. Try to imagine a line going through your graph around where the points are, that might help you see where other points would be. I hope that makes sense let me know if you need anything else I'm always happy to help :)
