What are the coordinates of the vertex of the function f(x)=x^2+10x−3? (–5, –28) (–5, 28) (5, –28) (5, 28)

polet [3.4K]

Answer:

(-5,-28)

Step-by-step explanation:

Given

$f(x)=x^2+10x - 3$

Required

Find the coordinates of the vertex

Given that the function is a quadratic function;

The general form of a quadratic function is

$f(x)= ax^2+bx +c$

By comparison;

$a = 1\ b = 10\ and\ c = -10$

To calculate the coordinates of the vertex;

we start by calculating the x-coordinate;

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

Substitute 10 for b and 1 for a

$x = \frac{-10}{2*1}$

$x = \frac{-10}{2}$

$x = -5$

Substitute $x = -5$ in the given function;

$y=x^2+10x - 3$

$y=(-5)^2+10*-5 - 3$

$y=25-50 - 3$

$y=-28$

<em>Hence, the coordinates of the vertex is (-5,-28)</em>

How do I write this fraction as a decimal 14 3/5

Softa [21]

we have

$14 \frac{3}{5}$

This is a mixed number

we know that

A mixed number is a combination of a whole number and a fraction.

$14 \frac{3}{5}$ is equal to

$14 +\frac{3}{5}$

where

$14$ is the whole number

$\frac{3}{5}$ is the fraction

$\frac{3}{5}=0.60$

$14 +\frac{3}{5} =14+0.60\\ \\ =14.60$

therefore

the answer is

$14.60$

Books: Josephine has seven chemistry books, three history books, and six statistics books. She wants to choose one book of each

Jobisdone [24]

Answer:

Step-by-step explanation:

we have totally 7+3+6=16 books.

let us choose one book from the all these books;

by using permutation formula we will get the answer

$P(n,r)=\frac{(n)!}{(n-r)!} \\$

$P(7,1)=\frac{(7)!}{(7-1)!} = 7\\\\\ P(3,1)=\frac{(3)!}{(3-1)!} = 3\\\\ P(6,1)=\frac{(6)!}{(6-1)!} = 6\\\\$

all these process are related to each other so we should multiply them

7*3*6=126
