Answer:

It is the second choice.

Step-by-step explanation:

This is a linear relationship because for every increase of 3 in x there is an increase of 3 in y.

But it is not a proportional relationship because it does not pass through the origin.

Answer: Mika has not described a proportional relationship. Although it is a linear function, it does not pass through the origin.

Step-by-step explanation: if you place those points on a graph, they do create a linear function; the line just doesn't pass through the origin.

Find the sum of the series given in sigma notation.

Kryger [21]

Answer:

Option b is correct 175

Step-by-step explanation:

n = 7

k = 6

3k -2 ------1

put k = 6 in above eq. for finding first term

a1 = 3(6) - 2 = 18 - 2 = 16

put k = 7 in above eq. for finding first term

a2 = 3(7) - 2 = 21 - 2 = 19

a3 = 3 (8) - 2 = 24 - 2 = 22

16, 19 , 22, ... //Arithmetic series formation

a1 = 16 , a2 = 19

d = a2 - a1 = 19 - 16 = 3 //Difference of first two terms

Using sum forumula for arithmetic series

sum = $\frac{n}{2}(2a1 + (n-1)d)$

= $\frac{7}{2}(2a1 + (7-1)d)$

= $\frac{7}{2}(2(16) + (6)3)$

= $\frac{7}{2}(32 + 18)$

= $\frac{7}{2}(50)$

= 7 * 25

= 175

Brainliest if it its right

Anika [276]

Answer:

A = <u>40</u> $mm^{2}$

Step-by-step explanation:

The equation for finding the area of a trapezoid is $A= \frac{a + b}{2}h$ .

In this equation, a=4, b=6, h=8.

$A = \frac{4 + 6}{2}8$ .

4+6=10
10/2=5
5x8=40

Hope this helps!
