<span>number of strikes hour,  f(x) = 2x + 5,

Domain, nonnegative values; range, values greater than −2.5 --> FALSE . The minimum value of f(x) is when x = 0, which drives to f(x) = 5 => -2.5 is no in the range.

Domain, nonnegative values; range, values greater than or equal to 5 --> TRUE. f(x) is defined for zero and all positive x, hours, and the set of images is  equal or greater than 5.


x = 0, f(x) = 5

x =1, f(x) = 2 + 5 =7

x = 2, f(x) = 2(2) + 5 = 9

x = 3, f(x) = 11

Komok [63]

Answer: Amber use 30 feet of basic tiles and 6 feet of decorative tiles.


Step-by-step explanation:

Let x be the foot  of basic tiles and y be the foot of decorative tiles.

Now, according to the question, we have the following equations

x+y=36\\y=36-x\ .......(1)\\\\8x+20y=36\times10\\2x+5y=90.......(2)\ \ \ [\text{divide equation by 4}]

Put y=36-x in (2), we get

2x+5(36-x)=90\\\Rightarrow2x+180-5x=90\\\Rightarrow-3x=-90\\\Rightarrow\ x=30\\\\\Rightarrow\ y=36-30=6

Hence, Amber use 30 feet of basic tiles and 6 feet of decorative tiles.

Answer:

Let's imagine the image of the zoo.

The diameter is basically the length of the circle.

The penguin swam the radius.

To find the radius, we need to divide the diameter by 2.

The diameter is 20 meters.

20 \div 2 = 10 meters.

2 x pi x 10 = 62.83185307

62.83185307/2 = 31.41592654

Answer = 31.41592654
