Rhe sum of three consecutive ofd numbers is 87. What is the smallest of these numbers?
neonofarm [45]

Answer:

The smallest of the said odd numbers is 27

Step-by-step explanation:

Since it is 3 odd numbers that sums up to 87, the first thing to do is to divide 87 by 3

That is 87/3 = 29, which is an odd number

The nearest odd  numbers to 29 are 27 and 31, and the total of all these three odd numbers is 87

That is 27+29+31 = 87, which are consecutive odd numbers.

The smallest odd number here is therefore 27

Identify the​ vertex, the axis of​ symmetry, the maximum or minimum​ value, and the range of the parabola for y=x^2+6x+13
charle [14.2K]

Answer:


Step-by-step explanation:

First we can determine the x value of our vertex via the equation:

x=\frac{-b}{2a}

Note that in general a quadratic equation is such that:

ax^2+bx+c

In this case a,b and c are the coefficients and so a=1, b=6 and c=13.

Therefore we can determine the x component of the vertex by plugging in the values known and so:

x=\frac{-b}{2a}=\frac{-6}{2(1)}=\frac{-6}{2}=-3

Now we can determine the y-component of our vertex by plugging in the x-component to the equation and so:

f(x)=x^2+6x+13\\\\f(-3)=(-3)^2+6(-3)+13\\\\f(-3)=4

Therefore our vertex is (-3,4).  Now in vertex our x component determines is the axis of symmetry so the equation for axis of symmetry is:

x=-3

Similarly, the y-component of our vertex is the minimum or maximum.  In this case it is the minimum you can determine this because a is positive meaning that the parabola will point up, and so the equation for the  minimum is:

y=4

The range of the formula is the smallest y-value meaning the minimum y=4 and all real numbers that are more than 4, mathematically:

Range = All real numbers greater than or equal to 4.

Someone help please :(
Hunter-Best [27]

Answer:

Answers in step-by-step.

Step-by-step explanation:

We are going to make Sarah the variable "s."

Using the given information, the following equation is derived to calculate Sarah's distance.

  • S=2n-5

And the following equation will be used to calculate what Sarah collected using "p" for pledged money.

  • P=18S

If Sarah collected $450 in pledges, we can use the preceding formula to calculate her distance.

  • P=18S
  • 450=18S
  • 450/18=S
  • 25 miles = S

Using Sarah's distance, we can calculate Semir's either the first equation.

  • S=2n-5
  • 25=2n-5
  • 30=2n
  • 15=n
  • Semir walked 15 miles.

We already found Sarah's distance to be 25 miles.

Now SungSo is making the same amount as Sarah. He collects $450 total, but he got $72 from his grandmother initially, so subtract 72 from 450 to get the amount he collected from walking.

  • 450-72=$378

His formula is the same as Sarah's, but we'll use SS for his variable.

  • P=18SS
  • 378 = 18SS
  • 378/18=SS
  • 21= SS
  • SungSo walked 21 miles.
