The maximum height the will rocket achieve is 21.76 feet and the time taken to return to the earth is 8/5 seconds.
What is velocity?Velocity is the rate of distance covered per time. Velocity could be average or instantaneous.
Average velocity can be given as;
Average velocity = total distance / total time taken
As per the given,
Velocity v = 40 feet/second
Height at time t as,
h = 40t - 16t²
Since, velocity = distance /time
dh/dt = velocity
dh/dt = 40 - 2 x 16 = 40 - 32t
v = 40 - 32t
At maximum height velocity will be zero,
40 - 32t = 0
32t = 40
t = 32/40 = 4/5 seconds
Maximum height = 40(4/5) - 16(4/5)²
Maximum height = 32 - 10.24 = 21.76 feet per second
Time taken = 2 x 4/5 = 8/5 seconds
Hence "The maximum height will rocket achieve is 21.76 feet and the time taken to return to the earth is 8/5 seconds".

Answer:
40 degrees
Step-by-step explanation:
90 degrees-50 degrees is equal to 90 degrees.
Answer:
a = 40°
Step-by-step explanation:
Since the total angle measurement is 90°, you can tell by the square indicator in the bottom right, you need to subtract 90 by 50. Doing to gives you 40. You can check by reversing this process. 50 + 40 = 90

A rain barrel has a diameter of 18 inches and a height of 3 feet. Find the total surface area to the nearest hundredth
Answer:
8.25 feet approx
Step-by-step explanation:
Given data
Diameter= 18inches to feet= 1.5 feet
radius= 1.5/2= 0.75 feet
Height= 3 feet
The expression for the total surface area of the barrel(cylinder) is given as
TSA= 2πrh+2πr^2
substitute
TSA= 2*3.142*0.75+ 2*3.142*(0.75)^2
TSA= 4.713+ 6.284*0.5625
TSA= 4.713+ 3.53475
TSA= 8.25 feet
Hence the TSA is 8.25 feet approx

Mrs. Warren has b boxes of Girl Scout cookies that
she wants to distribute to the members of her troop. If
she gives each girl 4 boxes, she will have 11 boxes left
over. If she wanted to give each student 5 boxes, she
would need an additional 12 boxes. How many girls
are in Mrs. Warren's Girl Scout troop?
A) 12
B) 23
C) 27
D) 32
Answer:
B) 23
Step-by-step explanation:
23 girls x 4 boxes each = 92 boxes
92 + 11 extra = 103
23 girls x 5 boxes each = 115 boxes
115 - 12 = 103
Mrs. Warren has 103 boxes and 23 girls in her Girl Scout troop.
Mrs. Warren has 103 boxes and 23 girls in her Girl Scout troop. so option B is correct.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given; Mrs. Warren has b boxes of Girl Scout cookies that she wants to distribute to the members of her troop.
If she gives each girl 4 boxes, she will have 11 boxes left over then,
23 girls x 4 boxes each = 92 boxes
92 + 11 extra = 103
If she wanted to give each student 5 boxes, she would need an additional 12 boxes then,
23 girls x 5 boxes each = 115 boxes
115 - 12 = 103
Hence, Mrs. Warren has 103 boxes and 23 girls in her Girl Scout troop. so option B is correct.

What is Dilation?Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.
When the triangle undergoes dilation, the length of its sides gets multiplied by 1/2 (dilation factor) but the angles remain the same ( since, the shape has to remain same).

Answer: [tex]15\times\frac{1}{2}[/tex]
Explanation:
Multiplying by 1/2 is the same as dividing by 2.
For example, if you have 10 slices of cake and 2 friends, then each friend gets 10/2 = 5 slices. We could also say [tex]10\times \frac{1}{2} = 5[/tex]
The fraction 1/2 converts to the decimal form 0.5, which means [tex]10 \times \frac{1}{2} = 10*0.5[/tex]

Answer:
24 cm
Step-by-step explanation:
The altitude from the centre to the chord is 5 cm and bisects the chord.
The radius of the circle is 26 cm ÷ 2 = 13 cm
There is a right triangle formed with legs 5 and x ( x is half the chord )
The hypotenuse is the radius, then using Pythagoras' identity
x² + 5² = 13²
x² + 25 = 169 ( subtract 25 from both sides )
x² = 144 ( take the square root of both sides )
x = [tex]\sqrt{144}[/tex] = 12
Then
length of chord = 2x = 2 × 12 = 24 cm
Answer:
24 cmStep-by-step explanation:
The chord, if the ends connected with the center, form an isosceles triangle with two sides being a radius of the circle.
We have:
Length of chord = xHeight of triangle = h = 5 cmRadius = r = 26/2 = 13 cmFrom the triangle we get:
(x/2)² + h² = r²x²/4 + 5² = 13²x²/4 = 144x/2 = 12x = 24The length of the chord is 24 cm
