The function y=-2(x-3)2 + 4 shows the daily profit (in hundreds of dollars)

B. The zeros are the hot dog prices at which they sell o hot dogs.
C. Zeros at x = 2 and x = 3
D. The zeros are the hot dog prices that give $0.00 profit (no profit).
Answers
Answer:
D. The zeros are the hot dog prices that give $0.00 profit (no profit).
Step-by-step explanation:
Given the function y=-2(x-3)² + 4
The zeros of the function are the points at which the graph of the function crosses the x axis if plotted. y is the daily profit (in hundreds of dollars) and x is the price of the hot dog. To find the zeros, we substitute x = 0 and solve.
Therefore: y=2(x-3)² + 4
0 = 2(x-3)² + 4
-2(x² - 6x + 9) + 4 = 0
-2x² + 12x - 18 + 4 = 0
2x² - 12x + 18 - 4 = 0
2x² - 12x + 14 = 0
2(x² - 6x + 7) = 0
x² - 6x + 7 = 0
Solving the quadratic equation gives:
x = 3 + √2 and x = 3 - √2
This means that the graph crosses x at 3 + √2 and 3 - √2.
The zeros of the function are 3 + √2 and 3 - √2. The zeros of the function is the point where y = 0, that is the point that the hot dog prices that give $0.00 profit (no profit).

I help! solve 12x^2+54x=-42
Answers
Answer: Hi!
Let's solve your equation step-by-step.
12x^2 + 54x = −42
Step 1: Subtract -42 from both sides.
12x^2 + 54x − (−42) = − 42 − (−42)
12x^2 + 54x + 42 = 0
Step 2: Factor left side of equation.

In ratio

__________________________________________
Given
IS PAID 473.88 FOR 38 1/4 HOURS OF WORK
38 1/4 hour = 38.25 hours
if we get ratio for payment per hour
we have
473.88 / 38.25 or 473.88 : 38.25
___________________________________
now we have to find payment for 40 hours
let that payment be x
thus, ratio for payment per hour in this case will be
x/40 or x:40
since
x:40 and 473.88 : 38.25 is representative of same program enhancement unit both ratio will be equal
thus
x:40 = 473.88 : 38.25
x/40 = 473.88 / 38.25
=> x = 40*(473.88 / 38.25 ) = 495.56
Thus, 495.56 should be p[aid for 40 hours.

Charlie is watching hot air balloons. Balloon A has risen at a 56° angle. Balloon B has risen at an 81° angle. If the distance from balloon A to the ground is 1,200 feet, how far is balloon B from balloon A? Round your answer to the nearest whole number. Two points labeled Balloon A and Balloon B are connected to a point labeled Charlie, which is on a straight line labeled ground. A dashed line connects point Balloon A to line Ground; another dashed line connects point Balloon B to line ground; both dashed lines form a right angle with line Ground; the angle formed from point Balloon A, point Charlie, and line ground measures x degrees; and the angle formed by point Balloon B, point Charlie, and line Ground measures y degrees.
A) 999 feet
B) 1,005 feet
C) 1,052 feet
D) 1,102 feet
Answers
The distance between Balloon B and Balloon A is 999 feet (correct to the nearest whole number); that is, Balloon B is 999 feet from balloon A
The diagram for the question is shown as described in the question in the attachment below.
From the diagram,
Let the height from balloon A to the ground be /AG/ and the height from balloon B to the ground be /BD/ and the point where Charlie is be C
/AG/ = 1200 feet
/AG/ = /BD/ = 1200 feet ( as shown in the diagram)
The distance between the two balloons is equal to /GD/
Also, from the diagram, /GD/ = /GC/ + /CD/
To find /GC/,
Consider ΔAGC
/AG/ = 1200 feet
/GC/ = ?
From the question, "Balloon A has risen at a 56° angle"
∴ x° = 56°
Using the formula
[tex]tan(x^{o} ) = \frac{/AG/}{/GC/}[/tex]
[tex]tan(56^{o}) = \frac{1200}{/GC/}[/tex]
[tex]/GC/ = \frac{1200}{tan(56^{o}) }[/tex]
/GC/ = 809.41 feet
To find /CD/
Consider ΔBCD
/BD/ = 1200 feet
/CD/ = ?
From the question, "Balloon B has risen at a 81° angle"
∴ y° = 81°
Using the formula
[tex]tan(y^{o} ) = \frac{/BD/}{/CD/}[/tex]
[tex]tan(81^{o}) = \frac{1200}{/CD/}[/tex]
[tex]/CD/ = \frac{1200}{tan(81^{o}) }[/tex]
/CD/ = 190.06 feet
Now, recall that /GD/ = /GC/ + /CD/
∴ /GD/ = 809.41 feet + 190.06 feet
/GD/ = 999.47 feet
/GD/ ≅ 999 feet (to the nearest whole number)
Hence, the distance between the two balloons is 999 feet
Balloon B is 999 feet from balloon A.

Answers
Answer: You will need 8 cup scales
Step-by-step explanation:
kg=1000 grams
2000/250=8
It is possible to measure 2 kilograms or 2000 grams in 8 cups, it is not possible to measure in three weighs.
What is Ratio?Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.
What is percentage?The percentage is defined as the ratio expressed as a fraction of 100.The percentage is denoted by sign of %.For example, if XYZ scored 46% marks in his test, it means that he scored 46 marks out of 100. It is written as 46/100 in the fraction form and 46:100 in terms of ratio.
Given data as :
9kg of oats and cup scales that gears of 50g and 200g.
Total oats need to measure = 9kg
Since, 1 kg contains 1000 grams.
1 kg = 1000 grams
2kg = 2000 grams
9kg = 9000 grams
Cup scales that gears as 50g and 200g
The number of one cup contains in gram = 200 + 50 = 250
The number of cups, considering that each cup weighs 250 grams.
The number of cups = 2000/250
The number of cups = 8
Hence, while it is possible to measure 2 kilograms or 2000 grams in 8 cups, it is not possible to measure in three weighs.
