The plot has an area of 78,125 square meters and is 125 meters wide. What is the length of the plot?

Answers

Answer 1
Answer: 625 meters long is the correct answer
Answer 2
Answer: Area formula: A = l * w or Area = length * width
Area: 78,125
Width: 125
Length: ?
78,125 = 125l
78,125/125 = 125l/125
625 = l

Which of the following graphs represent functions Circle your answers. If it is a function, state the domainand range. If the graph is not included, make a table and graph the function by hand.

Answers

Answer:

Step-by-step explanation:

A). y = |2x - 3| + 1

  Domain of function is defined by the x-values (Input values) and Range by the y-values(Output values).

  From the graph,

  Domain : (-∞, ∞)

  Range : [1, ∞)

B). Table of the input-output values of the function,

  y = x² - 2x + 1

  x         -2         -1           0         1          2

  y          9          4           1         0          1

 By graphing the function as attached,

 Domain of the function : (-∞, ∞)

 Range of the function : [0, ∞)

C). x² + y² = 3²

 Domain of the function : [-3, 3]

 Range of the function : [-3, 3]

D). x = 5

 Domain of the line : [5, 5]

 Range of the line : (-∞, ∞)

Answer B

If two 6-sided number cubes are rolled, what is the probability that a 2 is rolled on the first cube and a 5 is rolled on the second cube?

Answers

There are 6 sides on the number cubes, numbered 1-6.


The odds of rolling a 2 are 1 in 6, or 1/6

P(2)=1/6

The odds of rolling a 5 are 1 in 6, or 1/6

P(5)=1/6

P(2)*P(5)=1/6*1/6=1/36

The odds of rolling a 2 and a 5 are 1/36

Answer=1/36
the answer is going to be 1/36

At the local pet store, zebra fish cost $1.85 each and neon tetras cost $2.10 each. If Yumi bought 11 fish for a total cost of $21.60, not including tax, how many of each type of fish did she buy?A 7 zebra fish, 4 neon tetras
B 4 zebra fish, 7 neon tetras
C 6 zebra fish, 5 neon tetras
D 5 zebra fish, 6 neon tetras

Answers

Answer: C. 6 zebra fish, 5 neon tetras. Is $21.60

Step-by-step explanation:

1.85 • 6 = 11.10

2.10 • 5 = 10.50

11.10 + 10.50 = 21.60

$21.60

Is this an even or odd function? f(x)=5-3x

Answers

f(x)=5-3x \nx \in \mathbb{R}

A function is even if f(x)=f(-x) for every x in the domain.
f(x) \stackrel{?}{=} f(-x) \n5-3x \stackrel{?}{=} 5-3 * (-x) \n5-3x \stackrel{?}{=} 5+3x \n-3x-3x \stackrel{?}{=} 5-5 \n-6x \stackrel{?}{=} 0 \nx \stackrel{?}{=} 0 \nf(x)=f(-x) \Leftrightarrow x=0
f(x) is equal to f(-x) if and only if x=0, so the function isn't even.

A function is odd if -f(x)=f(-x) for every x in the domain.
-f(x) \stackrel{?}{=} f(-x) \n-(5-3x) \stackrel{?}{=} 5-3 * (-x) \n-5+3x \stackrel{?}{=} 5+3x \n3x-3x \stackrel{?}{=} 5+5 \n0 \stackrel{?}{=} 10 \n0 \not= 10 \n-f(x) \not= f(-x)
-f(x) is never equal to f(-x), so the function isn't odd.

The function is neither even nor odd.
