Answer:
8feet
Step-by-step explanation:
Given the height of the cabin modeled by the equation;
H(t)= -16cos(3.14t/45)+24
at the maximum height dH/dt = 0
dH/dt = 3.14/45(16)sin(3.14t/45)
dH/dt = 1.116sin(3.14t/45)
0 = 1.16sin(3.14t/45)
sin3.14t/45 = 0/1.16
sin3.14t/45 =0
3.14t/45 = arcsin0
3.14t/45 = 0
3.14t = 0
t = 0seccs
Substitute t = 0 into the expression
H(t)= -16cos(3.14t/45)+24
H(0) = -16cos(3.14(0)/45)+24
H(0) = -16cos0 + 24
H(0) = -16+24
H(0) = 8feet
Hence the maximum height of the cabin is 8feet
There are 20 marbles in a jar, 5 are purple, 6 are green, 4 are pink and 5 are blue. You randomly select one marble.
What is the probability that you will randomly select either a blue or purple marble?
Answer: 5/20 for blue and purple: Step-by-step explanation: it's a total of 20 marbles and 4 colors for each marbal so if i had to guess 5 for blue and purple is 10/20 when added but it says either that why i put 5 instead. If it's wrong answer I am very sorry i did not get it right.
Have a good day and i hope this help you with the question given above.

Find the 17th term of the arithmetic sequence –5, 1, 7, 13, …
A. 97
B. 107
C. 91
D. 87
Answer:
91
Step-by-step explanation:
the common diference is : d = ( 13)-(7)=(7)-(1)=(1)-(-5)=6
the first term is A1 = -5
the n-ieme term is : An = A1 +(n-1)d
An = -5+6(n-1)
An = 6n-11
the 17th term in the arithmetic sequence is : A17 = 6(17)-11 =91

C. 1/2
Step-by-step explanation:
(-9, 6) (-3, 9)
you need to subtract the x's and y's of both coordinates.
-9 - - 3 or -9 + + 3
x = 6
then, do y.
6 - 9 = 3
y = 3
then, divide the y by the x.
3/6 = 0.5
0.5 = 1/2
your answer is C. 1/2

A boat travels 8 miles upstream in the same amount of time it can travel 12 miles downstream. In still water the speed of the boat is 5 mi/h. What is the speed of the current?
Answer:
1 mi/hr
Step-by-step explanation:
Given that:
Speed in still water, s = 5 mi/hr
Let speed of current = x
Time = distance /speed
Upstream (subtract speed of current) = 5 - x
Upstream time = 8 / 5 - x - - - (1)
Downstream (add speed of current) = 5 + x
Downstream time = 12 / 5 + x - - - (2)
Equate (1) and (2)
8 / (5 - x) = 12/ (5 + x)
8(5 + x) = 12(5-x)
40 + 8x = 60 - 12x
40 - 60 = - 12x - 8x
-20 = - 20x
x = 1
Spwed of current = 1 mi/hr
An older person is 4 years older than 7 times the age of a younger person. The sum of their ages is 44. Find their ages
Answer:
5 yr and 39 yr
Step-by-step explanation:
Let x = the age of the younger
then 7x + 4 = the age of the older
Now x + 7x + 4 = 44
8x + 4 = 44
8x = 40
x = 5
7x + 4 = 7(5) + 4 = 35 + 4 = 39
Check: 5 + 39 = 44

y= 4
Jenna wants to build 8 birdhouses. She needs 2 3/5 square feet of plywood for each birdhouse. If the plywood costs $0.56 per square foot, how much will it cost Jenna to make her birdhouses?
Answer:
$11.76
Step-by-step explanation:
We first need to find the amount of plywood for all birdhouses.
2 3/5 * 8 = 104/5 or 20.8 or 20 4/5
Now we can solve the cost for all the birdhouses by multiplying the total amount of plywood needed by the price per square foot.
20.8 * 0.56 = $11.648 or estimated $11.65
Remember, the question might be different, so don't submit anything yet. If the people who sell the plywood only sell in integer numbers (meaning you can't buy 4/5 of a square foot of wood but can only by amounts with no fractions), then Jenna must buy 21 square feet of plywood and will have a little bit of wood left over. Now solve just like before.
21 * 0.56 = $11.76
Therefore the answer is $11.76 if she can only buy an integer amount of plywood or estimated $11.65. I think the best answer is 11.76.

What is the degree of the polynomial?
A. 0
B. 1
C. 3
D. 5
Answer:
D
Step-by-step explanation:
The degree of a polynomial is determined by the largest exponent of a term within the polynomial.
Given
7x³ + 4x - 5 + 8[tex]x^{5}[/tex]
The term with the largest exponent is 8[tex]x^{5}[/tex] with exponent 5
Thus the polynomial is of degree 5 → D

A tree 16 feet tall casts a shadow which forms an angle of 40° with the ground. How long is the shadow to the nearest hundredth of a foot?
Answer:
x = 19.06 feet
Step-by-step explanation:
Given that,
The length of a tree, h = 16 feet
It casts a shadow which forms an angle of 40° with the ground.
We need to find the length of the shadow. We can find it using trigonometry such that x be the length of the shadow. So,
[tex]\tan\theta=\dfrac{h}{x}\\\\x=\dfrac{h}{\tan\theta}\\\\x=\dfrac{16}{\tan(40)}\\\\x=19.06\ \text{feet}[/tex]
So, the length of the shadow is 19.06 feet.

Answer:
x = 17
Step-by-step explanation:
Assuming you require to find x
4x - 3 and 115 are same- side interior angles and supplementary, sum to 180°
4x - 3 + 115 = 180
4x + 112 = 180 ( subtract 112 from both sides )
4x = 68 ( divide both sides by 4 )
x = 17
