Plug in x-values and see which one has an incorrect y value.

(x, y)

x=0; y=0+7=7; CORRECT
x=2; y=2+7=9; INCORRECT
x=9; y=9+7=16; CORRECT
x=12; y=12+7=19; CORRECT

The point that is not on the online is (9, 16).

What is the distance between (8, -3) and (4, -7)?

lesantik [10]

Answer:

d=4√2

Step-by-step explanation:

distance formula = √(x2-x1)²+(y2-y1)²

d=√(4-8)²+(-7-(-3))²

d=√4²+(-4)²

d=√16+16 = √32=√2²*2²*2

d=4√2

Evaluate the sum from n equals five to nine of quantity three n plus two

goldfiish [28.3K]

Answer:

The given expanded sum of the series is $\sum\limits_{n=5}^{9}3n+2=115$

Step-by-step explanation:

Given problem can be written as

$\sum\limits_{n=5}^{9}3n+2$

To find their sums:

Now expanding the series

That is put n=5,6,7,8,9 in the given summation

$\sum\limits_{n=5}^{9}3n+2=[3(5)+2]+[3(6)+2]+[3(7)+2]+[3(8)+2]+[3(9)+2]$

$=[15+2]+[18+2]+[21+2]+[24+2]+[27+2]$

$=17+20+23+26+29$ (adding the terms)

$=115$

Therefore $\sum\limits_{n=5}^{9}3n+2=115$

Therefore the given sum of the series is $\sum\limits_{n=5}^{9}3n+2=115$

The given expanded sum of the series is $\sum\limits_{n=5}^{9}3n+2=115$

The formula for the area of a circle is A = πr2, where A = area and r = radius.

BaLLatris [955]

The area of a circle with radius of 5 feet is 25π square feet

Step-by-step explanation:

The area of a circle is found out using the formula

$A = \pi r^2$

Here A is the area

r is the radius of the circle and

pi is a constant

given

Radius = r = 5

We have to find the area in terms of pi

So,

$A = \pi r^2\\Putting\ r=5\\A = \pi *(5)^2\\A = 25\pi\ square\ feet$

Hence,

The area of a circle with radius of 5 feet is 25π square feet
