Answer:

y = (1/4)x^2 -x -4

Step-by-step explanation:

When you are given a focus and a vertex, the equation of a parabola can be written as ...

y = (1/(4p))(x -h)² +k . . . . . . vertex (h, k); focus-vertex distance p

Here, the vertex is (h, k) = (2, -5) and the focus-vertex distance is 1. That means the equation of the parabola in vertex form* is ...

y = (1/4)(x -2)² -5

Expanding this equation, we get ...

y = (1/4)(x² -4x +4) -5 = (1/4)x² -x +1 -5

Then the standard form equation is ...

y = (1/4)x² -x -4

_____

* In the UK, and perhaps other places, the vertex form is referred to as "standard form." You need to be aware of the form that is being requested here. I have answered using the US version of "standard form." YMMV

A quantity with an initial value of 6200 decays continuously at a rate of 5.5% per month. What is the value of the quantity after 4 years, to the nearest hundredth?

Answers

Answer:

410.32

Step-by-step explanation:

Given that the initial quantity, Q= 6200

Decay rate, r = 5.5% per month

So, the value of quantity after 1 month, [tex]q_1 = Q- r \times Q[/tex]

[tex]q_1 = Q(1-r)\cdots(i)[/tex]

The value of quantity after 2 months, [tex]q_2 = q_1- r \times q_1[/tex]

[tex]q_2 = q_1(1-r)[/tex]

From equation (i)

[tex]q_2=Q(1-r)(1-r) \\\\q_2=Q(1-r)^2\cdots(ii)[/tex]

The value of quantity after 3 months, [tex]q_3 = q_2- r \times q_2[/tex]

[tex]q_3 = q_2(1-r)[/tex]

From equation (ii)

[tex]q_3=Q(1-r)^2(1-r)[/tex]

[tex]q_3=Q(1-r)^3[/tex]

Similarly, the value of quantity after n months,

[tex]q_n= Q(1- r)^n[/tex]

As 4 years = 48 months, so puttion n=48 to get the value of quantity after 4 years, we have,

[tex]q_{48}=Q(1-r)^{48}[/tex]

Putting Q=6200 and r=5.5%=0.055, we have

[tex]q_{48}=6200(1-0.055)^{48} \\\\q_{48}=410.32[/tex]

Hence, the value of quantity after 4 years is 410.32.

The ratio of the measure of the sides of the triangle is 1/6: 1/3: 1/4 if the perimeter of the triangle is 13.5 inches. find the shortest side

Answers

Answer:

BRAINLIEST PLZZZZZ

Step-by-step explanation:

The shortest side of the triangle is 3 inches.

Given:

The ratio of the measure of the sides of the triangle is 1/6: 1/3: 1/4.

The perimeter = 13.5 inches.

Now, to find the shortest side.

Let the one side be = 1/6x

And the second side be = 1/3x

And the third side be = 1/4x

According to question:

1/6x + 1/3x + 1/4x = 13.5

x/6 = x/3 = x/4 = 13.5

Adding all the variables by taking common denominator we get:

⇒ 9x/12 = 13.5

Multiplying both sides by 12 we get:

⇒ 9x = 162

Dividing both sides by 9 we get:

⇒ x = 18

Thus, the sides of the triangle are:

1/6×18=3 inches.

1/3×18=6 inches.

1/4×18=9/2=4.5 inches.

Therefore, the shortest side of the triangle is 3 inches.

What is 365 divide by 3

Answers

Answer:

121.666667

Step-by-step explanation:

When 365 is divided by 3 the result or quotient is 121.66.

To calculate 365 divided by 3, we can perform long division:

Set up the division problem.

Determine how many times 3 can fit into the first digit of the dividend (3). The answer is 1.

Bring down the next digit (6) to the right of 3.

Determine how many times 3 can fit into the new number (36). The answer is 12.

Now, bring down the next digit (5) to the right of 12.

Determine how many times 3 can fit into the new number (53). The answer is 17.

Since there are no more digits to bring down, the division is complete.

The final result is: 365 ÷ 3

= 121.666...

Hence, 365 is divided by 3 to get 121.66.
