Answer:

The 2nd term in the sequence is -9.

Step-by-step explanation:

We have that:

$a(1) = -13$

$a(n) = a(n-1) + 4$

Find the 2nd term in the sequence.

This is a(2). So

$a(2) = a(2-1) + 4$

$a(2) = a(1) + 4$

Since a(1) = -13.

$a(2) = -13 + 4 = -9$

The 2nd term in the sequence is -9.

Answer:

The 2nd term in the sequence is -9.

Step-by-step explanation:

fa(1) = -13

a(n) = a(n-1)+4

Find the 2nd term in the sequence.

The sequence is an Arithmetic sequence.

Here the 1st term = -13

An = A(n-1) + 4

Therefore, the common difference (d) = 4

2nd term = first term + common difference

2nd term = -13 + 4 = -9

The answer is -9.

THEREFORE, The 2nd term in the sequence is -9.

What is the probability that a point chosen at random in the given figure will be inside the larger square and outside the small

liraira [26]

Answer:

51/100

Step-by-step explanation:

The probability that a point chosen at random in the given figure will be inside the larger square and outside the smaller square is equal to the ratio of the area of interest to the total area:

P(inside larger square and outside smaller square) = area of interest / total area

P(inside larger square and outside smaller square) = area inside the larger square and outside the smaller square / area of the larger square

Calculations:

1. Area inside the larger square: side² = (10 cm)² = 100 cm²

2. Area inside the smaller square = side² = (7cm)² = 49 cm²

3. Area inside the larger square and outside the smaller square

100 cm² - 49 cm² = 51 cm²

4. P (inside larger square and outside smaller squere)

51 cm² / 100 cm² = 51/100

If the difference of two numbers is 43 and the sum of the numbers is 13, what are the numbers?

meriva

Answer:

Numbers are 28 and -15

Step-by-step explanation:

Mark first number X, and second number Y, then:

x-y=43

and

x+y=13

We get system of two equations. Solve it by add both them together:

x-y+x+y=43+13

2x=56

x=28 we get first number

x+y=13

28+y=13

y=13-28

y=-15

On a number line, point S has coordinate 4.8 and point T has coordinate –2.3.

Ilya [14]

Answer:

The only answer that would work would be D) | 4.8 - ( -2.3) |

Step-by-step explanation:

This is because the distance is the absolute value of the difference of the two numbers. B and C would also work, but the 2.3 is not negative. A does not work because it is addition.
