A bag contains white,blue and red balls in the ratio 8:3:2.There are 10 red balls if 10 white balls and 10 blue balls are removed from the bag the new ratio is

Answers

Answer:

If you have 10 red balls, you have blue balls in proportion 3:2, so you have 15 blue balls. Moreover, you have white balls in proportion 8:2=4:1, so you have 40 white balls.

Removing 10 white and blue balls causes you to have 30 white, 10 red and 5 blue balls.

Since 30=5*6 and 10=5*2, the new proportion of white, red and blue balls is 6:2:1.

Mara found the length of time of an investment. The principal of the investment was $4,300, the interest rate was 6.2 percent, and the interest was $2,666. Mara made an error in her work.

I = p r t. 2666 = (4300) (0.062) t. 2666 = (266.6) t. StartFraction 266.6 over 2666 EndFraction = t. 0.1 = t.

Answers

well, 6.2% of 4,300 can't be over half. she has made a calculation error, and the real answer is (this is where the mistake was made) 4,300 * 0.062 (not 6.2, because percents are always divided by 100 to make them into a usable number), which is equal to $266.60.

Answers

Answer:

y-int = (0,-6/5)

x-int = (-3,0)

Step-by-step explanation:

to find the ints you have to replace the values by zero

y-int :

2(0) + 5y = -6

0 + 5y = -6

5y = -6

y = -6/5

y-int = (0,-6/5)

x-int:

2x + 5(0) = -6

2x + 0 = -6

2x = -6

x = -6/2

x = -3

x-int: (-3,0)

Given F(h)=9h+8 , find : f(3)

Answers

Answer: f(x) = x9h(x)

h(-1) = 2

h'(-1) = 5

We need to find h(x) first. Once we have h(x), we can find the derivative of f(x). Then evaluate the derivate when x = -1.

We know that derivative is the slope of the tangent line. In this case, the slope of the line tangent to h(x) at x=-1 is 5.

h(-1) = 2 has a coordinate point of (-1, 2).

2 = 5(-1) + b

2 = -5 + b

7 = b

h(x) = 5x + 7 -----> equation of the tangent line

f(x) = x9(5x + 7)

f(x) = 5x10 + 7x9

Take the derivative of f(x).

f'(x) = 50x9 + 63x8

f'(-1) = 50(-1)9 + 63(-1)8

f'(-1) = -50 + 63

f'(-1) = 13

Step-by-step explanation:

Answer:

f(3) = 35

Step-by-step explanation:

Since we are given f(3), that means h = 3

f(3) = 9(3) + 8

f(3) = 27 + 8

f(3) = 35

Step-by-step explanation:

The numbers in the other functions are less than one which means that they are decreasing.  

Six less then a number is equal to ten

Answers

The number is represented by n
n-6=10

To solve, add 6 to each side, giving you n=16

According to the information we can infer that the number is 16. So, 6 - 16 is 10.

What number does complete the operation correctly?

Let's assume the number is represented by 'x'.

According to the given information, six less than a number is equal to ten. This can be expressed as:

x - 6 = 10

To find the value of 'x', we can add 6 to both sides of the equation:

x - 6 + 6 = 10 + 6

This simplifies to:

x = 16

According to the information we can conclude that the number is 16. So, 6 - 16 is 10.

Step-by-step explanation:

f (n) = 5 (n + 2)

Let n=1

f (1) = 5 (1 + 2)

     = 5(3) = 15

Let n=2

f (2) = 5 (2 + 2)

     = 5(4) = 20

Let  n=3

f (3) = 5 (3 + 2)
