Answer:
The domain is the interval [5,∞)
Step-by-step explanation:
we have
we know that
The radicand (number under a radical) must be greater than or equal to zero
so
solve for x
Adds 5 both sides
therefore
The domain is the interval [5,∞)
All real numbers greater than or equal to 5
<u><em>Answer:</em></u>
The bird is approximately 9 ft high up in the tree
<u><em>Explanation:</em></u>
The required diagram is shown in the attached image
Note that the tree, the cat and the ground form a right-angled triangle
<u>Therefore, we can apply special trigonometric functions</u>
<u>These functions are as follows:</u>
<u>Now, taking a look at our diagram, we can note the following:</u>
α = 25°
The opposite side is the required height (x)
The adjacent side is the distance between the cat and the tree = 20 ft
Therefore, we can use the <u>tan function</u>
<u>This is done as follows:</u>
which is 9 ft approximated to the nearest ft
Hope this helps :)
Answer:
Rose will have 2.32$ leftover. She is able to get 3 more bouncy balls.
Step-by-step explanation:
To get the cost of 12 bouncy balls - 12*0.64 = 7.68$
To get the leftover amount - 10.00-7.68 = 2.32$
To find how many more bouncy balls she could get - 2.32/0.64 = 3.625 which is then 3 bouncy balls because you cannot buy .625 of a bouncy ball.
Answer:
1.6
Step-by-step explanation:
So, first, write down the number of jokers in each deck of cards.
That would be: 0, 1, 2, 2, 3
Then, add up all those numbers.
0+1+2+2+3=8
Now, divide that sum by the number of decks or cards shown in the data set, which would be 5.
8/5=1.6
So, the mean of the data in the dot plot shown is 1.6.
