Answer:

the center is (0,0) and the radius is 3

Step-by-step explanation:

Let's look at the graph... its center will be at (0,0), and the radius = 3

Imagine any line drawn through the center will "split" the circle in half, and can be called a line of symmetry.

How many significant figures in 0.003010

Tamiku [17]

4 significant figures.
we can start counting the numbers after all the zeros in front. the zeros in front doesn't count in. but the zeros after the first number that is 1 or larger counts.
therefore we only need to look at 3010

Aleonysh [2.5K]

Answer:

Juan got 18.50 miles per gallon.

Step-by-step explanation:

We are given the following in the question:

Odometer in the beginning of trip = 1460.3 miles

Odometer at the end of trip = 1830.2

Gallons of gas used for trip = 20 gallons

Distance of trip =

= Odometer at the end of trip - Odometer in the beginning of trip

$=1830.2-1460.3\\=369.9\text{ miles}$

Thus, the trip was of 369.9 miles.

Miles per gallon =

$=\dfrac{\text{Distance cover in trip}}{\text{Gallons of gas used}}\\\\=\dfrac{369.9}{20}\\\\=18.495\approx 18.50\text{ miles per gallon}$

Thus, Juan got 18.50 miles per gallon.

Help with this pleaseee

Answer:

Sum of 100 terms of the sequence = 15050

Step-by-step explanation:

Given expression which represents a sequence is,

$\sum_{r=1}^{100}(3r-1)$

So the sequence will be,

2, 5, 8, 11, 14..........

So, the given sequence is an arithmetic sequence with,

First term of the sequence 'a' = 2

Common difference 'd' = 5 - 2 = 3

Sum of 'n' terms of an arithmetic sequence is given by,

$S_n=\frac{n}{2}[2a+(n-1)d]$

Here, n = number of terms

a = first term

d = common difference

$S_{100}$ = $\frac{100}{2}[2(2)+(100-1)(3)]$

= 50[4 + 297]

= 15050

Therefore, sum of 100 terms of the sequence = 15050
