What is the equation of the parabola with vertex (6,7) and focus (7,7)?
Delicious77 [7]

Answer:

Step-by-step explanation:

If you plot these points on a coordinate plane, you see that they are on the same horizontal line, y = 7, with the focus 1 unit to the right of the vertex.  This means that the parabola is a sideways opening parabola, to the right, to be more specific.  That means that it has the basic vertex form

4p(x-h)=(y-k)^2

where p is the distance in units from the vertex to the focus, h is the first coordinate in the vertex, and k is the second coordinate in the vertex.  For us, p = 1, h = 6, and k = 7.  Now we will just fill the vertex form of the equation in with our values:

4(x-6)=(y-7)^2

We will solve this for x now by dividing each side by 4 and adding over the 6:

x=\frac{1}{4}(y-7)^2+6

PLZ HELP FAST the bank at which shareko deposits his money pays 5 1/4 % simple interest annually . How much interest will he ear
NemiM [27]

Answer:

Step-by-step explanation:

Simple interest rate applies only to the principal amount deposited and not the compounded amount. The formula for simple interest is expressed as

I = PRT/100

Where

I is the interest.

P is the principal or initial amount deposited.

R is the interest rate.

T is the duration in years.

From the information given,

P = $300.00

R = 5 1/4% = 5.25%

T = 6 months = 0.5 years

Therefore,

I = (300×5.25× 0.5)/100 =787.5/100

I = 7.875

The balance in the account at the end of this time will be

300 + 7.875 = $307.875

Need help please someone
salantis [7]

The answer to 9 would be (-3,-4) and (2,6) because if you plug in -3 for x in either of the equations and plug in 4 for y in the equations, both sides of the equation are the same number. also, if you plug in 2 for x and 6 for y both sides of the equation equal each other. The answer to 10 is (-1,1) and (7,33). if you plug them in they are equal:)
