an architect is designing a commemorative steel arch in the shape of a parabola. its axis is vertical and its feet are 300 yd. apart. If the focus of the parabolic arch is to be 80 yd. above the ground, how high must the arch be?
Answers
Answer:
125yd
option b is correct
The height of the arch from the ground will be 125 yards.
Given information:
An architect is designing a commemorative steel arch in the shape of a parabola.
Parabola is vertically placed and its legs are 300 yards apart.
The focus of the parabola is 80 yards above the ground.
Let a be the distance of focus from the vertex of the parabolic arch.
So, the equation of parabola will be,
[tex]x^2=-4ay[/tex]
Assume the origin is placed on the vertex of the parabola.
So, the coordinates of the legs will be,
(-150, -(80+a)) and (150, -(80+a))
Satisfy the above point with the equation of parabola as,
[tex]x^2=-4ay\\150^2=4a(80+a)\\a^2+80a-5625=0[/tex]
Solve the above quadratic equation as,
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\a=\dfrac{-80\pm\sqrt{80^2+4\times 1\times5625}}{2}\\a=\dfrac{-80\pm170}{2}\\a=-125, 45[/tex]
The value of a can't be negative. So, [tex]a=45[/tex].
So, the height of arch will be,
[tex]80+a=80+45\\=125\rm\;yd[/tex]
Therefore, the height of the arch from the ground will be 125 yards.

What number must be placed in the box in the equation below to produce an equation that has more than one solution: 5u+3(4u-6)=-3u-27+20u+ ▢
Answers
Answer: the number must be placed in the box is 9
suppose: the number must be placed in the box is x
have:
5u + 3(4u - 6) = -3u -27 + 20u + x
⇔ 5u + 12u - 18 = -3u - 27 + 20u +x
⇔ 17u + 3u - 20u = -27 + 18 + x
⇔ 0 = x - 9
⇔ x = 9
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
Simplifying both sides gives
17u - 18 = 17u - 27 + ▢.
Subtracting 17u from both sides gives
-18 = -27 + ▢.
If the number in the box is anything but 9, then the equation cannot be true, and the original equation has no solutions. If the number in the box is 9, then the two sides of the original equation are equivalent, and all values of u are solutions to the equation.

Brady went on a field trip to the water park. The cost of the trip was $19.99 to get into the park. He bought a hot dog for $3.50 and spent $2.10 on gas money. How much money did Brady spend?
Answers
Given:
Cost of the trip to get into the park = $19.99
Brady bought a hot dog for $3.50 and spent $2.10 on gas money.
To find:
The total money Brady spend.
Solution:
It is clear that,
Total money he spend = Cost of the trip to get into the park + Cost of a hot dog + Amount he spent on gas money
On substituting the values, we get
Total money he spend = $19.99 + $3.50 + $2.10
= $25.59
Therefore, the total money Brady spend is $25.59.

Mia has $50 on a gift card to her favorite coffee shop. Each time she visits the coffee shops she spends $3.75 on her favorite drink. Choose the equation that represents the relationship between x, the number of times she visits the coffee shop, and y, the total amount on her gift card.
Answers
Given:
Value of Gift card = $50
Each time she visits the coffee shops she spends $3.75 on her favorite drink.
To find:
The equation for the given situation.
Solution:
Let x be the number of times she visits the coffee shop, and y be the total amount on her gift card.
Cost of her favorite drink for one time = $3.75
Cost of her favorite drink for x times = $3.75x
Value of gift card is $50. So,
Amount on her gift card = 50 - Cost of her favorite drink for x times
[tex]y=50-3.75x[/tex]
Therefore, the required equation is [tex]y=50-3.75x[/tex].

Expression (C) [7 + 4(n - 1)] represents the nth number in the given arithmetic sequence.
What is an arithmetic sequence?A series of numbers called an arithmetic progression or arithmetic sequence has a constant difference between the terms. An arithmetic progression with a common difference of 2 is found, for instance, in the numbers 5, 7, 9, 11, 13, and 15. Starting with a number and repeatedly adding a fixed constant (d) to it is an easy technique to create a series.So, in the arithmetic sequence, there is a formula to find the nth term in the series.
Formula for aₙ term is: aₙ = a₁ + d(n - 1)Where d is the common difference and n is the number of terms.Here, d is 4 and a₁ is 7.Then, For aₙ term:
aₙ = a₁ + d(n - 1)aₙ = 7 + 4(n - 1)Therefore, expression (C) [7 + 4(n - 1)] represents the nth number in the given arithmetic sequence.

Shean has a piece of string 7/8 meter long. He uses 1/5 of he piece of string to tie a package and cuts the rest into 5 equal parts. What is the length of the pieces.
Answers
Answer:
7/50 meter
Step-by-step explanation:
Total piece of string = 7/8 meter
Used string = 1/5 of the piece of string
Used string =
1/5 of 7/8 meter
= 1/5 × 7/8
= 7/40 meter
Balance = Total string - used string
= 7/8 - 7/40
= 35-7/40
= 28/40
Balance = 28/40 meter
cuts the rest into 5 equal parts. What is the length of the pieces.
28/40 ÷ 5
= 28/40 × 1/5
= 28 / 200
= 7/50 meter
Length of each piece = 7/50 meter

What is the density of an object that has a mass of 20 grams and has a length of 8cm and a width of 2cm and a height of 5cm????
Answers
Answer:
Volume is the amount of space an object occupies. To determine the volume of any rectangular object, multiply the measurements of length, width, and height.
Volume = Length × Width × Height
Calculate the volume of this rectangular object.
Length = 3 cm
Width = 3 cm
Height = 12 cm
Volume = l × w × h
Volume = 3 cm × 3 cm × 12 cm
Volume = 108 cm3
Notice that the units for volume are cubic centimeters (cm3).
So 8 ÷ 25 = 0.32 and the units would be g/ cm3 . Other units of density could be g/L or g/ml or mg/ cm3 or kg/ m3 and the list could go on and on. Any unit of mass divided by any unit of volume.
