Butoxors [25]

42.86% error was in the scientist's estimation.

Step-by-step explanation:

Given data;

Approx amount = 4 ml

Exact amount needed = 7 ml

Percentage error = \frac{|Approx-Exact|}{Exact}*100

Percentage\ error=\frac{|4-7|}{7}*100\\Percentage\ error=\frac{|-3|}{7}*100\\Percentage\ error=\frac{3}{7}*100\\\\Percentage\ error=\frac{300}{7}\\Percentage\ error= 42.86\%

42.86% error was in the scientist's estimation.

Which of the following rules could represent the function shown in the table?
MariettaO [177]

Answer:

f(x) = 2x+1​

Step-by-step explanation:

Equation in slope intercept form y = mx + b where m = slope b = y-intercept

To find slope ,

m = (y2-y1)/(x2 - x1)

m = (3 - 1) / (1 - 0)

m = 32/1

m = 2

y-intercept b = 1

In this case y = 2x + 1 or f(x) = 2x+1​

A circle in the xy-plane has its center at (-2/3,-3/4)
Cloud [144]

Answer:

(x + 2/3)^2 + (y + 3/4)^2 = 5^2 (or 25).

Step-by-step explanation:

Start with the general equation of a circle with center at (h, k) and radius r:

(x - h)^2 + (y - k)^2 = r^2

Substitute -2/3 for h and -3/4 for k, and also 5 for r:

(x - [-2/3])^2 + (y - [-3/4])^2 = 5^2, or

(x + 2/3)^2 + (y + 3/4)^2 = 5^2 (or 25).
