PART B write an equation to model the temperature in Baltimore on this day
Answer:
See below for answers and explanations
Step-by-step explanation:
A) The midline would be the average of the high and low temperatures, therefore d=(44+26)/2=70/2=35. The amplitude would be the distance from the high and low temperatures to the midline. Since 44-35=9 and 35-26=9, then the amplitude is a=9.
B) The equation would be [tex]T=9sin(\frac{\pi}{12}x)+35[/tex]

A garden measuring 8 feet by 12 feet will have a walkway around it. The walkway has
a uniform width, and the area covered by the garden and walkway is 192 square feet.
What is the width of the walkway?
O 3.5 feet
O 6 feet
O 2 feet
O 4 feet
Answer:
2 feet
Step-by-step explanation:
By solving a quadratic equation, we will see that the width of the walkway must be 2 ft.
How to get the width of the walkway?
Remember that the area of a rectangle of length L and width W is:
A = L*W
In this case, we know that the dimensions are:
Length = 8ftWidth = 12ftNow, if we add a walkway of width x all around the garden, the new dimensions of the garden are:
Length = 8ft + 2xWidth = 12ft + 2xNow with these dimensions, the area is 192 ft^2, then we can write:
192 ft^2 = (8ft + 2x)*(12ft + 2x)
Now we need to solve that for x:
192 ft^2 = 96ft^2 + 4x^2 + 40ft*x
0 = 96ft^2 - 192ft^2 + 4x^2 + 40ft*x
0 = 4x^2 + 40ft*x - 96ft^2
This is a quadratic equation, the solutions are given by Bhaskara's formula:
[tex]x = \frac{-(40ft) \pm \sqrt{(40ft)^2 - 4*4*(-96ft^2)} }{2*4} \\\\x = \frac{-(40ft) \pm 56ft }{8}[/tex]
Notice that we have two solutions, but we only care for the positive one, so we take:
x = (-40ft + 56ft)/8 = 2ft
So the width of the walkway must be 2ft.

Jaxon built a treehouse with a base of 12 square yards. The volume of his treehouse was 108 cubic yards, how tall is the prism? Explain your answer.
Answer:
h = 9 yds, assuming his treehouse is a rectangular shape. 9 yds seems pretty high.
Step-by-step explanation:
area = bh
108 yd³ = 12 yd² x h
h = 108/12 = 9 yds
The prism is 9 yards tall
What is the Volume of Rectangular Prism?
The area occupied inside a rectangular prism is referred to as the volume of the prism. A polyhedron with two pairs of congruent and parallel bases is referred to as a rectangular prism. It has 12 sides, 6 faces (all of which are rectangles), and 8 vertices. Given that the rectangular prism is a three-dimensional (3D) shape, the units cm3, m3, and so forth are employed to express the volume of the rectangle prism. Any polyhedron that possesses all of these qualities is referred to as a cuboid in mathematics.
Given: base of the treehouse= 12 yards²
volume of the treehouse = 108 yards³
To find : how tall is the prism ( height of the treehouse) = ?
Formula Used : The volume of a rectangular prism is calculated using the formula volume of a rectangular prism (V) = l w h,
where "l" stands for base length
"w" for base width.
"h" refers to the prism's height.
Steps for calculating the height
Step 1: The foundation area of 12 square yards has previously been specified.
Step 2: The prism's volume is 108 cubic yards
Step 3: The given rectangular prism's volume = base area x height
=> 108 cubic yards = 12 x h
=> 108/ 12 = h
=> h = 9 yards
Since , the prism is 9 yards tall

there should always be even number of 0 if it wants to be a perfect square.
3 * 3 =9
30 * 30 =900. .......(2 0's)
300 * 300 = 9000...(4 0's and so on)
9000 does not meet this criteria so it isn't a perfect square.

Find the length of a rectangular prism if the volume is 70 m3, the width is 2 m, and the height is 7 m.
5 m
8 m
7 m
6 m
Answer:
5 m
Step-by-step explanation:
Use the volume formula, V = lwh
Plug in the volume, width, and height, then solve for l (the length)
V = lwh
70 = (l)(2)(7)
70 = 14l
5 = l
So, the length of the rectangular prism is 5 m
Answer:
Solution :-We have
Volume = 70 m³
Width = 2 m
Height = 7 m
Length = Volume/Width × Height
Length = 70/2 × 7
Length = 70/14
Length = 5 m
