Answer:

y = 2(m + 1/2)^ -25/2

Step-by-step explanation:

vertex form is:

y = 2m^2 + 2m - 12

y + 12 + ( )___ =( ) 2m^2 + 2m + ___

Because a is not one, you must divide the entire right side by the a value, which is 2. Then place the 2 in the parenthesis.

y + 12 + (2)__ = (2) m^2 + m + __

Take half of b, b being one.

Half of be is 1/2. Now square it to get 1/4. Place that value in the blanks.

y + 12 + (2)1/4 = (2) m^2 + m + 1/4

Now simplify the left side and factor the right side.

y+ 12 + 1/2 = 2(m + 1/2)^2

y + 25/2 = 2(m + 1/2)^2

Subtract 25/2 from both sides.

y = 2(m + 1/2)^ -25/2

Answer:

1/12

Step-by-step explanation:

Since the pizza was cut into 6, each of the slices = 1/6.

But because the pizza was then cut into half, it makes each slice = 1/12

6 x 2 = 12

Therefore the answer is 1/12.

The correct answer is:

7/10

Explanation:

Finding the totals of each column and row, we find:

There are 3+2+1 = 6 children in the baseball league.

There are 7+2+1 = 10 children in the softball league.

There are 3+7 = 10 children in the 7-9 division.

There are 2+2 = 4 children in the 10-12 division.

There are 1+1 = 2 children in the 13-15 division.

There are a total of 10+6 = 16 children.

We start with the information that the team is a member of the softball league.  There are 10 children in this league; this is the denominator of the probability.

There are 7 children in the 7-9 division that are in the softball league.  This gives us the probability 7/10.

Bank of Peace= 15000(1+0.025)³=£16153.36

Bank of Trust=15000(1+0.038)=£15570

£15570(1+0.01)=£15882.95

Bank of Peace is the best choice.

I would choose the  Bank of Peace to get the most of my savings.

Formula for calculating the compound value of the savings at the Bank of Peace = FV = P (1 + r)^n

FV = Future value  

P = amount deposited  

R = interest rate  

N = number of years

£15,000 x (1.025)^3 = £16,153.36

Interest earned at the Bank of Trust in the first year = £15,000 x 0.038 = $570

Total amount at the end of the first year = $570 + £15,000 = £15,570.

Value for the two extra years = $15,570 x (1.01)^2 =$15,882.96

Answer:

The letter "n" can be considered a term, a variable, and an expression. It cannot be considered a "constant", therefore the answer is "a constant".

Our first step is the find the lcm of 4 and 12 so we can add the two fractions without having a problem.

The lcm of 4 and 12 is clearly 12 because 12 is a multiple of 4. 12 divided by 4 is 3, so you must multiply by 3/3 to be able to add the two fractions.

1/4*(3/3)=3/12.

So, 3/12+5/12=7/12.

We need a common denominator to add the fractions

The common denominator is 12

1/4*3/3 + 5/12

3/12 + 5/12

The length of KM is [tex]\sqrt{109}[/tex] units.

Step-by-step explanation:

Given the statement:  KLMN is a trapezoid, ∠N= ∠KML, FD=8, [tex]\frac{LM}{KN}=\frac{3}{5}[/tex], F∈ KL, D∈ MN , ME ⊥ KN KF=FL, MD=DN, [tex]ME=3\sqrt{5}[/tex].

From the given information it is noticed that the point F and D are midpoints of KL and MN respectively.

The height of the trapezoid is [tex]3\sqrt{5}[/tex].

Midsegment is a line segment which connects the midpoints of not parallel sides. The length of midsegment of average of parallel lines.

Since [tex]\frac{LM}{KN}=\frac{3}{5}[/tex], therefore LM is 3x and KN is 5x.

[tex]\frac{3x+5x}{2}=8[/tex]

[tex]\frac{8x}{2}=8[/tex]

[tex]x=2[/tex]

Therefore the length of LM is 6 and length of KN is 10.

Draw perpendicular on KN form L and M.

[tex]KN=KA+AE+EN[/tex]

[tex]10=6+2(EN)[/tex]                (KA=EN, isosceles trapezoid)  [tex]EN=2[/tex]

[tex]KE=KN-EN=10-2=8[/tex]

Therefore the length of KE is 8.

Use Pythagoras theorem is triangle EKM.

[tex]Hypotenuse^2=base^2+perpendicular^2[/tex]

[tex](KM)^2=(KE)^2+(ME)^2[/tex]

[tex](KM)^2=(8)^2+(3\sqrt{5})^2[/tex]

[tex]KM^2=64+9(5)[/tex]

[tex]KM=\sqrt{109}[/tex]

Therefore the length of KM is [tex]\sqrt{109}[/tex] units.

The factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. 8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 equals 40,320.

In Mathematics, the factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. For instance, 8! means multiplying together 8, 7, 6, 5, 4, 3, 2 and 1. So, the calculation would look like this: 8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 40,320. Therefore, the value of 8! is 40,320.

Step-by-step explanation:you have to turn all the mixed numbers into improper fraction so 1 1/3 is 16/12 1 1/4 is 15/12 and if you add them you get 2 7/12 and that minus 3 6/12 is 11/12

There are 11/12 ounces of black pepper in Catalina's seasoning packet.

Catalina uses a 3 1/2 ounce packet of seasoning for her steaks.

This packet contains 1 1/3 ounces of garlic powder and 1 1/4 ounces of onion powder.

To find out how many ounces of black pepper are in the packet, we need to subtract the combined weight of the garlic and onion powders from the total weight of the seasoning packet.

Garlic powder: 1 1/3 ounces = 4/3 ounces

Onion powder: 1 1/4 ounces = 5/4 ounces

Total seasoning packet: 3 1/2 ounces = 7/2 ounces

We then add the amounts of garlic and onion powders to get their combined weight:

4/3 + 5/4 = (16 + 15) / 12 = 31/12 ounces

The next step is to subtract the combined weight of the garlic and onion powder from the total weight of the seasoning packet:

7/2 ounces - 31/12 ounces = (7\*6 - 31) / 12 = (42 - 31) / 12 = 11/12 ounces.

Answer:

The correct answer is $2,50.

Step-by-step explanation:

The unit rate is what we use to determine the price of a single unit, when something is sold in a group, as in this case 5 ounces.

We have been told that $ 12.50 is the price for 5 ounces, but what we want to know is how much 1 ounce costs.

To determine this, what we must do is divide the total price by the quantity of ounces, in order to determine the unit price:

12.50 / 5 = 2.50

In this way we can verify that the unit price of 5 ounces is $ 2.50

The correct answer is $2,50,  is the unit rate for $12.50 for 5 ounces.

Here, we have,

Answer:

21.33 to nearest hundredth

Step-by-step explanation:

Inverse Variation is y = k / x where k is a constant.

Plug in the given values to find k:-

16 = k/4

k = 4*16 = 64 so the equation  of variation is y = 64/x.

So when x = 3,   y = 64/3 = = 21.33 to nearest hundredth.

The value of y when x = 3 is 21.33

The value of y = 21.33

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be A

The value of x = 4

The value of y = 16

Now , the value of y is inversely proportional to x

So ,

y ∝ 1/x

y = k/x

where k is the constant of proportionality

So , k = yx

Now , substituting the value of x and y in the equation , we get

k = 16 x 4

k = 64

So , when the value of x = 3 ,

y = k / x

y = 64 / 3

y = 21.33

Hence , The value of y when x = 3 is 21.33
