What are the roots of the polynomial f(x)=x^2+9x-70?

Answers

Answer 1
Answer: Roots of the polynomial are values of x when f(x)=0,so
to find the roots of the polynomial we need to solve the equation
x²+9x-70=0    , a=1, b=9,c=-70     

x= \frac{-b+/- \sqrt{ b^(2)-4ac } }{2a}

x= (-9+/- √(81+4*1*70) )/(2) = (-9+/- √(361) )/(2)= (-9+/-19)/(2)  x_(1)=5, x_(2)=-14

A bag contains 10 red marbles, 15 yellow marbles and 5 green marbles. What is the probability of drawing a red or green marble from the bag?

Answers

Probability = 

             (number of ways it can come out the way you want)
divided by
             (total number of ways it can come out).

Total number of ways to draw a marble = 30 (marbles in the bag).

Number of ways it can succeed = 15 (number of red or green ones)

Probability = 15/30 = 1/2 = 50% .
10(red) plus 5(green) equals 15. red plus green plus yellow equals 30 15/30 - 50%

What is -3/5 x 5/16 x 7/12 ➗-3/16 x -5/7?

Answers

Answer:

-49/60.

Step-by-step explanation:

To simplify the expression -3/5 x 5/16 x 7/12 ÷ -3/16 x -5/7, we can follow these steps:

1. Multiply the numerators and denominators of all the fractions together:

(-3 x 5 x 7) / (5 x 16 x 12) ÷ (-3 x -5) / (16 x 7)

2. Simplify the multiplication of the numerators and denominators separately:

-105 / 960 ÷ 15 / 112

3. When dividing fractions, we can multiply by the reciprocal of the second fraction:

-105 / 960 x 112 / 15

4. Multiply the numerators and denominators together:

(-105 x 112) / (960 x 15)

5. Simplify the multiplication:

-11760 / 14400

6. Reduce the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 240:

-49 / 60

How do I solve this?The Sugar Sweet Company is going to transport its sugar to market. It will cost $4900
to rent trucks, and it will cost an additional $175 for each ton of sugar transported. Let
C represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported. Write an equation relating C to S, and then graph your equation using the axes below.

Answers

C = 4900 + 175S

The graph will cross the y-axis at 4900 and show a slope of 175/1 . Good luck graphing. If you choose the right scale, the graph will be easier. Increment by  by 500 on the yaxis and 25 on the x-axis.
