The height of the tree is 4.15m
We are given that
Height of Joshua, h=1.85 m
Length of tree's shadow, L=39.55 m
Distance between the tree and Joshua=35.4 m
We have to find the height of the tree.
BC=35.4 m
BD=39.55m
What is the height?CD=BD-BC
CD=-35.4 m=4.15 m
EC=1.45 m
All right triangles are similar. When two triangles are similar then the ratio of their corresponding sides is equal.
\(\triangle ABD=\triangle ECD\)
\(\frac{AB}{EC}=\frac{BD}{CD}\)
Substitute the values
\(\frac{AB}{1.45}=\frac{39.55\times 1.45}{4.15} \\\\AB=20.39\)
Hence, the height of the tree=20.39 m

A pizza chain offers cheese pizzas with a choice of these toppings:
pepperoni, onion, sausage, mushrooms, and anchovies.
a) Explain why the pizza chain can claim to offer 32 different pizzas.
b) Another pizza chain claims that with its choice of toppings, it can
create just over 1000 pizzas. What is the minimum number of
toppings it must offer?
Step-by-step explanation:
The pizza chain has 5 different topings.
Number of different pizzas = 2⁵ = 32.
We have 2^n >= 1000.
Since 2⁹ = 512 and 2¹⁰ = 1024,
the minimum number of toppings is 10.

The volume of the solid obtained by rotating the region bounded by the curve y = 1 - (x - 5)² in the first quadrant about the y-axis is 51π cubic units.
What is the volume of the solid obtained by rotating the region in the first quadrant bounded by the given curve about the y - axis?To find the volume of the solid obtained by rotating the region bounded by the curve y = 1 - (x - 5)² in the first quadrant about the y-axis, we can use the method of cylindrical shells.
The formula for the volume using cylindrical shells is:
V = 2π ∫ [a, b] x * h(x) dx
Where:
- V is the volume of the solid
- π represents the mathematical constant pi
- [a, b] is the interval over which we are integrating
- x is the variable representing the x-axis
- h(x) is the height of the cylindrical shell at a given x-value
In this case, we need to solve for x in terms of y to express the equation in terms of y.
Rearranging the given equation:
x = 5 ± √(1 - y)
Since we are only interested in the region in the first quadrant, we take the positive square root:
x = 5 + √(1 - y)
Now we can rewrite the volume formula with respect to y:
V = 2π ∫ [c, d] x * h(y) dy
Where:
- [c, d] is the interval of y-values that correspond to the region in the first quadrant
To determine the interval [c, d], we set the equation equal to zero and solve for y:
1 - (x - 5)² = 0
Expanding and rearranging the equation:
(x - 5)² = 1
x - 5 = ±√1
x = 5 ± 1
Since we are only interested in the region in the first quadrant, we take the value x = 6:
x = 6
Now we can evaluate the integral to find the volume:
V = 2π ∫ [0, 1] x * h(y) dy
Where h(y) represents the height of the cylindrical shell at a given y-value.
Integrating the expression:
V = 2π ∫ [0, 1] (5 + √(1 - y)) * h(y) dy
To find h(y), we need to determine the distance between the y-axis and the curve at a given y-value. Since the curve is symmetric, h(y) is simply the x-coordinate at that point:
h(y) = 5 + √(1 - y)
Substituting this expression back into the integral:
V = 2π ∫ [0, 1] (5 + √(1 - y)) * (5 + √(1 - y)) dy
Now, we can evaluate this integral to find the volume
V = 2π ∫ [0, 1] (5 + √(1 - y)) * (5 + √(1 - y)) dy
To simplify the integral, let's expand the expression:
V = 2π ∫ [0, 1] (25 + 10√(1 - y) + 1 - y) dy
V = 2π ∫ [0, 1] (26 + 10√(1 - y) - y) dy
Now, let's integrate term by term:
\(V = 2\pi [26y + 10/3 * (1 - y)^\frac{3}{2} - 1/2 * y^2]\)] evaluated from 0 to 1
V = \(2\pi [(26 + 10/3 * (1 - 1)^\frac{3}{2} - 1/2 * 1^2) - (26 * 0 + 10/3 * (1 - 0)^\frac{3}{2} - 1/2 * 0^2)]\)
V = 2π [(26 + 0 - 1/2) - (0 + 10/3 - 0)]
V = 2π (25.5)
V = 51π cubic units

segment?
Write the coordinates as decimals or integers.
M =
Answer:
The midpoint (x,y)=(6,9)
Step-by-step explanation:
We need to find midpoints(x,y) of the line segment having endpoints S(8, 8) and T(4, 10)
The formula to find midpoint is:
\(Midpoint(x,y)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\\)
We are given: \(x_1=8, y_1=8, x_2=4 , y_2=10\)
Putting values and finding midpoint
\(Midpoint(x,y)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\Midpoint(x,y)=(\frac{8+4}{2},\frac{8+10}{2})\\Midpoint(x,y)=(\frac{12}{2},\frac{18}{2})\\Midpoint(x,y)=(6,9)\)
So, the midpoint (x,y)=(6,9)

"From Martina's World"
Martina, a 3-year-old with flaming red hair and bright blue eyes, is admitted to the pediatric unit w
bronchitis. In addition to her medical condition, Martina has autistic disorder. Martina does not seem
nurse's presence in the room but is intensely occupied with a blue stuffed dog. The nurse is prepar
ister scheduled oral medications to the child. Martina's mother is present in the room.
What approach would help the nurse to establish a trusting relationship with Martina
To establish trust with Martina, the nurse should show respect, use non-verbal communication, incorporate play, involve the parent, and individualize the approach.
To establish a trusting relationship with Martina, the nurse can employ several approaches:
Respect and empathy: The nurse should approach Martina with genuine respect and empathy, recognizing her unique needs and individuality. This can be conveyed through a calm and patient demeanor.
Non-verbal communication: Since Martina may not be responsive to verbal cues, the nurse can utilize non-verbal communication to establish connection and trust. This can include maintaining eye contact, using gentle touch, and respecting Martina's personal space.
Play and familiar objects: Given Martina's engagement with the blue stuffed dog, the nurse can incorporate play into their interactions. Bringing familiar objects or toys that Martina finds comforting can help create a sense of familiarity and security.
Parental involvement: Involving Martina's mother in the care process can be beneficial. The nurse can communicate with the mother, seek her input, and involve her in the administration of medications. This helps build trust not only with Martina but also with her caregiver.
Individualized approach: Recognizing Martina's autistic disorder, the nurse should tailor their approach to her specific needs. Understanding her sensory sensitivities and preferences can help create a safe and comfortable environment.
By implementing these strategies, the nurse can foster trust and a positive therapeutic relationship with Martina, promoting her overall well-being and care.

It would take Al

Answer:
It would take Al 7.5 days to build the grill alone.
Step-by-step explanation:
Since Tim and Al are bricklayers, and Tim can construct an outdoor grill in 5 days, and if Al helps Tim, they can build it in only 3 days, to determine how long would it take Al to build the grill alone should be done the following calculation:
1/5 + X = 1/3
0.20 + X = 0.333
X = 0.333 - 0.20
X = 0.1333333
X = 1 / 7.5
Therefore it would take Al 7.5 days to build the grill alone.

Step-by-step explanation:
According to the combinations: Number of ways to choose r things out of n things = C(n,r)
Given word: "georgianna"
It is a sequence of 10 letters with 2 a's , 2 g's , 2 n's , and one of each e, o,r, i.
If we think 10 blank spaces, then in a sequence we need 2 spaces for each of g.
Number of ways = C(10,2)
Similarly,
1 space for 'e' → C(8,1)
1 space for 'o' → C(7,1)
1 space for 'r' → C(6,1)
1 space for 'i' → C(5,1)
1 space for 'a' → C(4,2)
1 space for 'n' → C(2,2)
Required number of different sequences = C(10,2) ×C(8,1)× C(7,1)× C(6,1)×C(5,1)×C(2,2).
Hence, the correct option is E) C(10, 2)C(8, 1)C(7, 1)C(6, 1)C(5, 1)C(4, 2)C(2, 2)
