Before calculators were around, why was it's advantageous to use logarithms to calculate roots

1 answer:

4 0

Because logarithms were a lot less time-consuming than other methods of finding roots. They were also more accurate in the sense that it was harder to make a mistake.

Answer:

X= (300 s + 200 b + 42 d )mg

Step-by-step explanation:

Amount of spinach=300 ml

Amount of berries =200 ml

amount of dressing = 42 ml

Vitamin C in one ml of spinach = s mg

Vitamin C in 300 ml of spinach = 300 s mg

Vitamin C in one ml of berries=b mg

Vitamin C in 200 ml of berries = 200 b mg

Vitamin C in one ml of dressing = d mg

Vitamin C in 42 ml of dressing = 42 d mg

Let total vitamin C be = x

Then

X= (300 s + 200 b + 42 d )mg

is the required expression

Answer:

2. The y-intercept is 33 ft. The ball is 33 feet away from the wall.

3. It will take the ball 11 seconds to touch the wall.

4. The slope is -3 ft. The ball is rolling toward the wall at 3 ft per second

Step-by-step explanation:

Let x be the number of seconds.

We are told that a ball is rolling at a rate of 3 ft per second toward a wall that is 33 feet away.

Since the ball is rolling towards wall at a rate of 3 ft per second. This means that remaining distance between wall and ball is decreasing 3 ft with each passing second. Hence, the slope of our line will be negative 3 ft.

As initially ball was 33 feet away from wall, so our y-intercept will be 33.

Upon substituting our values in slope-intercept form of equation we will get equation of our line representing remaining distance between ball and wall after x seconds as:

$y=-3x+33$

Let us find the number of seconds that ball will take to touch the wall by finding the x-intercept of our line. Since x-intercept is the point when line crosses x-axis and at this point y equals 0. The x-Intercept of a line is obtained by putting the value of y as zero in the equation of a line.

$0=-3x+33$
