Okay, So Y equals 0,
And C equals 1,
And D equals 2, 

If you Input the numbers into the equation it is proved true, meaning my answers are correct. Hoped I Helped :)

The answers are 2 and 3. After multiplying together cy^3 and 9y^d, you'll get 9c*y^d+3. From there, set it equal to 18y^6. You can split apart 18y^6 into 18 and y^6, so you can solve for the different variables. Split apart 9c*y^d+3 into 9c and y^d+3, and set 9c=18. C will equal 2. Solve the other to get 3.

Can anyone help me out? thanks

Answer:

450 cm

Step-by-step explanation:

12 degrees is 1/30 of the circumference because there are 360 degrees in a circle.

The minor arc length of 15 is in the same ratio to the circumference as  the 2 angles , so the circumference = 30 * 15 - 450 cm.

Please answer, the best answer gets brainliest

Answer:

Median is 18.

Mean is 22.

Step-by-step explanation:

Median has to be ordered from least to greatest:

1, 9, 17, 18, 25, 41, 43

then the median is the number in the middle, which is 18.

Mean is the sum of all the numbers, divided by 7 (because there are 7 numbers given)

25+18+9+1+43+17+41= 154

154/7 = 22

Use the discriminant to determine the number of solutions to the quadratic equation 3x^2+5x=-1
kari74 [83]

Answer:

Two real distinct solutions

Step-by-step explanation:

Hi there!

<u>Background of the Discriminant</u>

The discriminant b^2-4ac applies to quadratic equations when they are organised in standard form: ax^2+bx+c=0.

All quadratic equations can be solved with the quadratic formula: x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}}.

When b^2-4ac is positive, it is possible to take its square root and end up with two real, distinct values of x.

When it is zero, we won't be taking the square root at all and we will end up with two real solutions that are equal, or just one solution.

When it is negative, it is impossible to take the square root and we will end up with two non-real solutions.

<u>Solving the Problem</u>

<u />3x^2+5x=-1<u />

We're given the above equation. It hasn't been organised completely in ax^2+bx+c=0, but we can change that by adding 1 to both sides to make the right side equal to 0:

3x^2+5x+1=0<u />

Now that we can identify the values of a, b and c, we can plug them into the discriminant:

D=b^2-4ac\\D=(5)^2-4(3)(1)\\D=25-4(3)(1)\\D=25-12\\D=13

Therefore, because the discriminant is positive, the equation has two real, distinct solutions.

I hope this helps!

serg [7]

Answer:

\frac{9}{11}

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

We have:

3 red cards

6 blue cards

2 green cards.

What is the probability that the card is not green?

3 + 6 + 2 = 11 cards, of which 3 + 6 = 9 are not green. So

\frac{9}{11} probability that the card is not green
