If x = –3 is the only x-intercept of the graph of a quadratic equation, which statement best describes the discriminant of the e

kompoz [17]

$\text{ if } \Delta=0\text{ then there is one x-intercept : }x=-\dfrac{b}{2a}\\\\
\text{ if } \Delta\ \textless \ 0\text{ then there are no x-intercept : } x=\varnothing\\\\
\text{ if } \Delta>0\text{ then there are two x-intercept : }x_1,x_2=\dfrac{-b\pm\sqrt{\Delta}}{2a}\\\\$

<u>Answer </u>: <span>The discriminant is 0</span>

I suck at math can someone help please??

Zielflug [23.3K]

6/7 × 4 would be the correct answer. This is because 6/7 × 4= 3 3/7 which is equal to 4/7 × 6= 3 3/7. No other expression would equal 4/7 × 6

Acapulco, Mexico and Hyderabad, India both lie at 17° north latitude, and lie very nearly halfway around the world from each oth

Nataly_w [17]

In solving this problem we can consider Earth to be a sphere. When we have a circle, then we can use this formula to find arc length:
$L=2 \pi R \frac{C}{360}$
Where:
L= arc length (in this problem it is disance we need to travel)
R = radius of circle (in this problem it is equal to a radius of Earth)
C = angle we need to pass

We are told that two cities lie halfway around the world. If we fly to west this means angle is 180°.
This gives an arc length of:
$L=2* \pi *3960* \frac{180}{360} \\ \\ L=12440.71 miles$

If we want to fly to north we need to go to 90° northern latidtude and then back to 17° latitude. This means angle is:
C=2*(90-17)=2*73°=146°
This gives an arc length of:
$L=2* \pi *3960* \frac{146}{360} \\ \\ L=10090.8 miles$

We can see that flying north is shorter. It is shorter by:
12440.71 miles - 10090.8 miles = 2349.91 miles

The shop declare a discount of 20% and later a discount of 15% after

Oksi-84 [34.3K]

In order to calculate the equivalent discount, consider the principle number is 100,
Then, 100 - 100 * 0.20 = 100 - 20 = 80
Now, 80 - 80 * 0.15 = 80 - 12 = 68

So, Total discount would be: 100 - 68 = 32%

Hope this helps!
