Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule.

lubasha [3.4K]

Answer:

The answer is option C.

Step-by-step explanation:

The arithmetic sequence is given by

$A(n) = - 6 + (n - 1)( \frac{1}{5} )$

where n is the number of terms

For the first term

n = 1

So we have

$A(1) = - 6 + (1 - 1)( \frac{1}{5} )$

$= - 6 + (0)( \frac{1}{5} )$

$= - 6$

For the fourth term

n = 4

$A(4) = - 6 + (4 - 1)( \frac{1}{5} )$

$= - 6 + (3)( \frac{1}{5} )$

$= - 5 \frac{2}{5}$

For the tenth term

n = 10

$A(10) = - 6 + (10 - 1)( \frac{1}{5} )$

$= - 6 + (9)( \frac{1}{5} )$

$= - 4 \frac{1}{5}$

Hope this helps you

What are the solutions to the system of equations {-x+y=4 {y+12=x^2+x

Gnoma [55]

Answer:

Step-by-step explanation:

$y=4+x$ ............................................ (1)

$y=x^2+x-12$ ............................................ (2)

now equate both (1) and (2)

$4+x=x^2+x-12$

$=>x^2=16$

$x=-4,4$

now substitute the values of x ,

when $x=-4$ , y becomes 0

when $x=4$ , y becomes 8

so, solution set:

$(-4,0)$ and $(4,8)$

The answer would be 400$. This is because 40 x 10 = 400.

Explain please and tell me how to do it ?

SCORPION-xisa [38]

The trick to calculating the area here is to subdivide the diagram into smaller parts. For example, there's a 3 cm-by-3cm square. The rectangle is 4 cm by 8 cm.. The triangle has a base of 5 cm and a height of 3 cm.

Total area = area of square + area of rectangle + area of triangle

= 9 cm^2 + 32 cm^2 + (1/2)(5 cm)(3 cm)

= (9 + 32 + 7.5) cm^2

= 48.5 cm^2 (total area of figure)
