Which equation, when graphed, has x-intercepts at (-1,0) and (-5,0) and a y-intercept at (0, -30)?

Vladimir [108]

If a function has roots -1 and -5, it must be in the form

$f(x)=a(x+1)(x+5)$

We can fix the coefficient a by imposing the passing through (0,-30):

$f(0)=-30=a(1)(5)\iff a=-6$

So, the function is

$f(x)=-6(x+1)(x+5)$

F(x) 2 square root -x^2+10 x what’s the domain

SSSSS [86.1K]

The domain of the function are all real numbers greater than 10

<h3>Domain of a function</h3>

Domain are values of the independent variables for which the function exist.

Given the function below;

$f(x)=2\sqrt{-x^2+10x}$

For the function to exist, then;

-x^2+10x = 0

-x^2 = -10x

x = 10

Hence the domain of the function are all real numbers greater than 10

A trader buys 200 oranges for 60 kobo and sells them at 8 for 12 kobo.what is his gain

astraxan [27]

$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's solve ~

Cost price for each Orange :

$\qquad \tt \dashrightarrow \: \dfrac{60}{200}$

$\qquad \tt \dashrightarrow \:0.3 \: \: kobo$

Now, Cost price for 8 oranges :

$\qquad \tt \dashrightarrow \:0.3 \times 8$

$\qquad \tt \dashrightarrow \:2.4 \: \: kobo$

And we have been given that selling price for 8 oranges is 12 kobo.

Therefore, the gain is :

$\qquad \tt \dashrightarrow \:12 - 2.4$

$\qquad \tt \dashrightarrow \:9.6 \: \: kobo$

Percentage gain is ~

$\qquad \tt \dashrightarrow \: \dfrac{9.6}{2.4} \times 100$

$\qquad \tt \dashrightarrow \:4 \times 100$

$\qquad \tt \dashrightarrow \:400 \: \%$
