what is the equation of the following graph in vertex form? HELP PLS
Answer:
y = (x - 2)^2 + 1
Step-by-step explanation:
The general equation of a parabola in vertex form is y-k = (x-h)^2. Here, we can see immediately from the graph that the vertex is at (2, 1). Thus, the equation of this particular parabola takes the form y - 1 = a(x - 2)^2. We must still determine the value of a. Note that the graph goes through (0, 5). Thus, 5 - 1 = a(0 - 2)^2, or
4 = 4a. Thus, a = 1, and the equation of this parabola is y - 1 = (x - 2)^2, or, after simplification, y = (x - 2)^2 + 1.
if (5)=-3, then the point ???? is on the graph of f
f(x) = y
f(5) = -3 therefore the point is (5, -3).

find the exact value of cos 5pi/3
Answer:
1/2
Step-by-step explanation:
The angle 5pi/3 shows up in the 3rd quadrant and is equivalent to the angle 300 degrees. The "reference angle" of 300 degrees is 60 degrees; the reference angle in this case has the same trig function values as does 300 degrees. Thus, the cosine of 5pi/3 is the same as the cosine of 60 degrees, which is 1/2.
Using equivalent angles, it is found that:
[tex]\cos{\left(\frac{5\pi}{3}\right)} = \frac{1}{2}[/tex]
[tex]\frac{5\pi}{3}[/tex] is an angle in the fourth quadrant, as [tex]\frac{2\pi}{3} \leq \frac{5\pi}{3} \leq 2\pi[/tex].
To find the equivalent in the first quadrant to an angle in the fourth quadrant, we subtract [tex]2\pi[/tex] from the angle, then:
[tex]2\pi - \frac{5\pi}{3} = \frac{6\pi}{3} - \frac{5\pi}{3} = \frac{\pi}{3}[/tex]
Just as in the first quadrant, the cosine is positive in the fourth quadrant, thus, applying the equivalent angle:
[tex]\cos{\left(\frac{5\pi}{3}\right)} = \cos{\left(\frac{\pi}{3}\right)} = \frac{1}{2}[/tex]

calculate the volume of each rectangular prism. include the unit in your number sentence ??
A cement walk 3 ft wide is placed around the outside of a rectangular garden plot that is 20ft by 30ft. Find the cost of the walk at $12.25 a square yard
Let us calculate the area of the walk.
Since the width of the walk is 3 feet, and the walk will be placed all the 4 sides,
Length of the plot including walk = 20 + (2 × 3) = 20 + 6 = 26 feet.
Breadth of the plot including walk = 30 + (2 × 3) = 36 feet.
Area of the plot including walk = 26 × 36 square feet.
Area of the plot = 20 × 30 square feet.
Area of the walk = (26 × 36) - (20 × 30)
= 936 - 600
= 336 square feet.
= [tex]\frac{336}{3(3)}[/tex] square yards
= 37.3 square yards
Cost of the walk per square yard = $12.25.
Therefore, total cost of the walk = 12.25 × 37.3 = $456.92.

Which is the graph of y = 1/x?
answer: the first graph
explanation:
it would not be the second one because it is a slope (y = mx + b) and so would be the third choice.
i don't think it would be the last one because it's going only up to 40. which the equation say only y = 1/x and it's not a big number equation.

Jack mixes yellow and blue paint to make green paint that he will use to paint his basement. He uses a ratio of 3 pints of yellow paint for every 2 pints of blue paint. Jack pours 18 pints of yellow paint into a bucket. How many pints
of blue paint should jack add to the bucket?
To maintain the ratio of 3:2 for yellow to blue paint, if Jack uses 18 pints of yellow paint, he needs to use 12 pints of blue paint.
Explanation:In this problem, Jack is using a ratio of 3 pints of yellow paint for every 2 pints of blue paint. This ratio simplifies to 3:2. If he uses 18 pints of yellow paint, we can set up a simple proportion to find out how much blue paint he should use.
Yellow : Blue = 3 : 2 = 18 : x. To solve for x, we cross-multiply: 3*x = 2*18. Which leads us to 3x = 36, and dividing both sides by 3 gives x = 12. Therefore, Jack should use 12 pints of blue paint.

y= 2+4.3x when x= -6
Answer:
y= -23.8
Step-by-step explanation:
I don't know if this is the right answer but you can try
When x is -6, y is approximately -23.8.
The given equation is y = 2 + 4.3x, and you want to find the value of y when x = -6.
Substitute x = -6 into the equation:
y = 2 + 4.3 * (-6)
Now, calculate the value:
y = 2 - 25.8
Simplify:
y = -23.8
When x = -6, the value of y is -23.8.
This means that if you plug in x = -6 into the equation, you will get y = -23.8 as the corresponding y-coordinate on the graph.
This represents a point on the line described by the equation y = 2 + 4.3x when x is -6, y is -23.8.

Are -3.9 and -0.99 on the same side or the opposite side of zero ?
Same side. Locate -3.9 on the number line. Then -0.99 is to the right of -3.9, with both numbers being on the same side (that is, on the left side) of zero.
Same side, think of it as a number line. there is a left side for negitives, and a right for positives. Every negitive number is on the same side, while the positives have their own side too. Only if it was a positive with a negitive it would be on opposite sides.

the sunflower is the only single flower that grows as high as 3 meters. it can grow 30 cm each week. in which week does the sunflower reach a height of 3 meters ?
To determine when a sunflower reaches a height of 3 meters, given it grows at a rate of 30 cm per week, we divide 300 cm by 30 cm per week to find that the sunflower will reach the height in the 10th week.
The question asks us to determine in which week a sunflower, which can grow 30 cm each week, reaches a height of 3 meters.
Calculation of Weeks Required for Sunflower to Reach 3 Meters:
Firstly, we need to convert the final desired height from meters to centimeters, since the growth rate is given in centimeters per week:
3 meters = 300 centimeters
Next, we divide the final desired height by the weekly growth rate to find the number of weeks:
300 cm / 30 cm/week = 10 weeks
Therefore, the sunflower reaches a height of 3 meters in the 10th week.

A) not enough information
B)90
C)98
D)82
Answer: B) 90
Since c is perpendicular to b (given) and line 'a' is parallel to line c (also given), this means line 'a' is perpendicular to line b.
Put another way, angles 5, 6, 7, 8 are all 90 degrees (since c is perpendicular to b). If a || c, then angles 2 and 6 are corresponding angles that are congruent.
So this is why angle 2 is also 90 degrees.

Hi,
Here is the solution.
3 years = 36 months
Leased amount for 3 years = $3000 + 36*350
= $3000 + $12600
Leased amount for 3 years = $15600
Residual value = $12000
Assume you didn't buy the car, you took it for lease, so your expense = $15600.
Now Assume you bought the car for $21,000.
After using 3 years, you can sell it for $12000.
Your expense = $21,000 - $12,000 = $9000.
Conclusion:
It is less expensive to buy the car.
The cost for buying the car and selling it after 3 years = $9000.
Hope you will understand the steps. Thank you :)

Write the expression in standard form. three divided by quantity three minus twelve i.
3/(3 - 12i)
To simplify this, multiply both sides by (3 + 12i)
(3 - 12i)(3 + 12i)
Distributive property.
3(3 + 12i) - 12i(3 + 12i)
9 + 36i - 36i - 144i^2
Simplify.
9 - 144i^2
i^2 can be interpreted as -1.
9 + 144
Combine like terms.
153 is the simplified version of the bottom half of the expression.
Now for the top half.
3(3 + 12i)
Distributive property.
9 + 36i
We can simplify this further by factoring.
3(3 + 12i)/153
1 + 4i/17
1/17 + 4i/17 is the simplified version of the expression. (This is your answer.)
Let me know if you have any other questions.
To write the expression in standard form, divide 3 by the quantity 3 - 12i and rationalize the denominator by multiplying by the conjugate of the denominator to simplify to (3 + 12i)/51.
To write the expression in standard form, 3 divided by (3 - 12i), you need to rationalize the denominator by multiplying both the numerator and denominator by the conjugate of the denominator to eliminate the imaginary part. The conjugate of 3 - 12i is 3 + 12i.
Therefore, multiplying by the conjugate gives you: (3/(3 - 12i)) x ((3 + 12i)/(3 + 12i)).
This simplifies to the standard form: (3(3 + 12i))/(3^2 - (12i)^2) = (3(3 + 12i))/(9 + 144) = (3 + 12i)/51.
What value should going to the empty boxes to complete the calculation for finding the product of 0.98×0.73? both numbersare the same however only input the answer at one time and your answer.
Answer:
Missing same value is 0.02
Step-by-step explanation:
Instead of multiplying big decimal numbers we put short cut by making 0.98 as a difference of near integer and one decimal.
i.e 0.98 =1-0.02
Since 0.02 is the same for other also other term
0.73 = 0.75-0.02
Now product can be done very easily.
Steps are shown below:
0.98x0.73
= (1-0.02) (0.75-0.02)
= 0.75 -0.02(1+0.75)+0.0004
= 0.7504-(0.035)
= 0.7154
=0.44

What is an expression for the total cost of feeding h horses?
Let's say the cost to feed each horse is $5.00.
The expression would be written as:
(5.00)h or simplified as 5h
This is because you are multiplying the cost for feeding each horse by the amount of horses, represented as h.
If you are feeding 6 horses you would substitute the h for 6 giving you the expression:
5(6)
which equals $30 total.

Roberto has a sample of an unknown liquid. The label in the bottle of the sample indicates that the liquid has a mass of 117 grams and a volume of 15 cubic centimeters. What is the liquid in the bottle? gasoline milk water mercury
Answer:
It is Milk
Step-by-step explanation:
The liquid in the bottle has mass given in grams and the mass of that substance is 117 grams.
The volume of the substance is 15 cubic centimeters.
Now, using the formula of density we can estimate which substance could it be.
[tex]d=\frac{m}{v}[/tex], where 'd', is the density, 'm' is the mass, and 'v' is the volume of the substance.
Plugging the value of mass and volume we get:
[tex]d=\frac{117}{15} =7.8g/cm^3[/tex]
So the density of the substance is 7.8 grams per cubic centimeter.
It cannot be water since the density of water is 1 grams per cubic centimeter.
It cannot be gasoline because its density is 0.77 grams per cubic centimeter.
It cannot be mercury because the density of mercury is 13.56 grams per cubic centimeter.
Since, the density in this case matches the density of thick milk and hence,therefore, the liquid in the bottle is milk.
