Answer:

2 times

Step-by-step explanation:

Well let's first graph the quadratic equation,

Look at the image below ↓

By looking at the image below we can tell that the graph touches the x axis 2 times at,

(-1,0)

(1 1/3,0)

Thus,

the parabola touches the x axis twice.

Hope this helps :)

E3: Amab sells an article to Vivek at a profit of 15% and Vivek sells it to

Bogdan [553]

Answer:

the cost price is 27,715

Step-by-step explanation:

Let the cost price be x

As Amab sells to Vivek at 15% profit

So the selling price be

= 115 ÷ 100 × x = 1.15x

And Vivek sells to sagar at a profit of 10%

= 1.15x × 110 ÷ 100

= 1.265x

Now sagar pays it for 35,060

So , the cost price be

1.265x = 35,060

x = 27,715

Hence, the cost price is 27,715

Find the distance between each pair of points.

BigorU [14]

Answer:

Distance between the points (-3,1) and (1, -2),

$\sqrt{ {(1 + 3)}^{2} + {( - 2 - 1)}^{2} }$

$= \sqrt{ {(4)}^{2} + {( - 3)}^{2} }$

$= \sqrt{16 + 9} = \sqrt{25} = 5$

The data set below gives the number of points Micah scored during each basketball game this season. (5, 12, 27, 44, 30, 9, 18, 2

Julli [10]

Answer:

Yes there is an outlier and it is 44

Step-by-step explanation:

Outliers are values that seems to be far greater and lower than the rest of the data

From the given data we can see that 44 is much greater than the rest of the data making it an outlier in the data set

The removal or addition of the value when calculating the mean will make a huge difference in the resulting mean of the data. That's why they are called an outlier

What is the y-intercept of the quadratic function f(x)=(x-8)(x+3)

Semmy [17]

The curve passes through y-axis at $x=0$

Substituting $x=0$ into $f(x) = (x-8)(x+3)$ we have:

$f(0) = (0-8)(0+3)$
$f(0)=(-8)(3)$
$f(0)=-24$

The y-intercept is -24
