Answer:

Vertex is (-5, -1)

(-3, 3) is a point on the parabola.

Step-by-step explanation:

f(x) = x² + 10x + 24

Let (h, k) be the vertex

h = -b/2a = -10/2(1) = -5

k = f(-5) = (-5)^2 + 10(-5) + 24

  = 25 - 50 + 24 = -1

Vertex is (-5, -1)

Now, let x be some value different than -5, say -3

f(-3) = (-3)^2 + 10(-3) + 24

      = 9 - 30 + 24 = 3

So, (-3, 3) is a point on the parabola.

What formula do i use when it tells me to find the area with a given circumference? If you know please give an example as well,
liberstina [14]

Answer:

Step-by-step explanation:

A = C^2 / 4 x pi

so if the circumfernce was 10 you would square it to make it 100 and then you would do 4 x pi to get 12.57 ( rounded).

you would then just divide 100 by 12.57 = 7.96 ( rounded)

hope it helped

How many solutions exist for the system of equations graphed below?
Anestetic [448]

Answer:

One

General Formulas and Concepts:

<u>Algebra I</u>

  • Reading a coordinate plane
  • Solving systems of equations by graphing

Step-by-step explanation:

If 2 lines are parallel, they will have no solution.

If 2 lines are the same, they will have infinite amount of solutions.

We see from the graph that the 2 lines intersect at one point, near x = 1.5.

∴ our systems has 1 solution.

Sum of all natural numbers from100to300 which are divisible by 4and 5 is​
My name is Ann [436]

If x is a number that is both divisible by 4 and 5, then

\begin{cases}x\equiv0\pmod4\\x\equiv0\pmod5\end{cases}

4 and 5 are coprime, so we can use the Chinese remainder theorem to solve this system and find that x=20n is a solution to the system, where n is any integer. Simply put, any multiple of 20 fits the bill.

Now, there are 11 numbers between 100 and 300 that are divisible by 20 (100, 120, 140, and so on). We have 20n=100 when n=5, so the sum we want to compute is

\displaystyle\sum_{n=5}^{15}20n=\boxed{2200}
