9x1/10+6x1/100+4x1/1,000 how can this measurement be written as a decimal

omeli [17]

The above equation can be written as
$\frac{9}{10} + \frac{6}{100} + \frac{4}{1000}$
Then make all the denominators the same
$\frac{900}{1000} + \frac{60}{1000} + \frac{4}{1000} = \frac{964}{1000}$
964/1000 = 0.964

A quadratic equation has exactly one real number solution. Which is the value of its discriminant?

zhenek [66]

<h3>Answer: 0</h3>

The discriminant is the number under the square root of the quadratic formula

$x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}$

The discriminant formula is $D = b^2-4ac$

If D = 0, then the whole square root portion is 0 meaning we end up with the solution $x = -\frac{b}{2a}$

A father is now twice as old as his son. If the sum of their ages ten years ago was fifty two, how old are they today?

Oliga [24]

Answer:

24 and 48

Today, the son is 24 years old, and the father is 48 years old.

Step-by-step explanation:

(x - 10) + (2x - 10) = 52

3x + 20 = 52

3x = 72

x = 24

The father is 2 times his son's age.

= 2(24)

= 48

So, the son is 24 and the father is 48.

10 years ago, son was 14 and father was 38, if added, this adds up to 52, so we know our calculations are correct.

What is an equation of the line that passes through the point (-4,3) and is

zysi [14]

Answer:

The perpendicular line 4x − 5y = 20 has a slope of 4/5 and as such, the slope of the required line = -5/4

(y - 3)/(x + 4) = -5/4 simplify to get the required equation: 5x + 4y + 8 = 0
