How did newton know that 1%of 80 is 0.8

1 answer:

8 0

So,

Newton knows that 1% of anything really just means moving the decimal point two places to the left.

Examples:
1% of 10 = 0.1

1% of 389,092,192 = 3,890,921.92

1% of 3.1415926 = 0.031415926

Knowing this, Newton figures that all he has to do is move the decimal place two places to the left.

1% of 80 = 0.8

The graph shows a function.<br> Find the value of b and d.

True [87]

Answer:

<em>The required values are b=-6 and d=4</em>

Step-by-step explanation:

The graph corresponds to the function

$r(x) =x^2+bx^2+8x+d$

We are required to find the values of b and d.

They can be found by using two points that are clearly visible on the graph. For example, the points (0,4) and (2,0) belong to the function. Substituting their values in the function:

$4 =0^2+b*0^2+8*0+d$
