Answer:
The equation of the given circle is X²+y²+4x- 12y+15=0
Answer:
Measurement error.
Step-by-step explanation:
Measurement Error are the error when there is difference found in true value of data and measured quantity of data. This difference could be found if we are missing some data in the sample.
The error could be reduced by carefully designing the process of data collection and it´s measurement.
Measurement error are classified into two type of error:
- Random error.
- Systematic error.
Answer:
x = 6 cm
Step-by-step explanation:
Given ratio of sides of similar figures = a : b , then
ratio of areas = a² : b²
Here ratio of areas = 5 : 45 = 1 : 9 , so
ratio of sides = 
: 
= 1 : 3
Thus side of B is 3 times side of A
x = 3 × 2 = 6 cm
Answer:
y=2x +3
Step-by-step explanation:
The slope hits the points (-1,2) and (0,2). If you count how many units are right and up, then that's your slope. In this case, the distance between those two points are 1 right and 2 up which is the same thing as 2. The y-intercept is 3 since the slope crosses the y-axis there.
Answer:
80
Step-by-step explanation:
(20 x 2) + (10 x 4) = 40 + 40 = 80
brainliest please ;)
