Which of the following correctly shows the quadratic formula for the given equation? 3x2 - 6x + 8 = 0

1 answer:

7 0

The quadratic formula is expressed as:

x = (-b +/- √(b^2 - 4ac) ) / 2a

where a, b and c are the coefficients of the quadratic equation with the form ax^2 + bx + c=0

Therefore, the quadratic equation would be:

a = 3
b = -6
c = 8

x = (-(-6) +/- √((-6)^2 - 4(3)(8) ) / 2(3)

Hope this helps.

One year, Mr James travels 8 x 10^3 miles for his job. The next year he traveled 1 x 10^4 miles. How many more miles did he trav

nignag [31]

Answer:

2 000 miles

Step-by-step explanation:

In the first year, Mr James travels 8 x $10^{3}$ miles = 8 000 miles.

The second year, he traveled 1 x $10^{4}$ miles = 10 000 miles.

Comparing the distance covered in the two years,

10 000 miles - 8 000 miles = 2 000 miles

Therefore, Mr James travels 2 000 more miles in the second year than he did the first year.

Let's assume that Mr James conveys himself to his place of work all through the first year in his private car. But in the second year, there were some days in which the car was not available. So he had to go for his job by public transportation. This itch during those days, could cause an increase in the distance covered from his home to his place of work for the second year.

50. If angles are complementary, what’s value of x?

maks197457 [2]

Answer:

x = 14

Step-by-step explanation:

For complementary angles, the sum of two angles is equal to 90 degrees.

We have,

$m\angle ABC = 4x-10\\\\m\angle DBC = x+30$

ATQ,

$4x-10+x+30=90$

Taking like terms together,

4x+x =90-30+10

5x = 70

x = 14

So, the value of x is 14.
