Answer:

The first one (the one with the months)

Step-by-step explanation:

A function is when an x value doesn't have more that one y value (y can have more than one x value, though). On the teachers and pets one, Ms. Valverde has two pets, so that doesn't count. On the shapes one, the orange square is pointing to another orange square and a triangle, so that doesn't count. The last one has 7 equaling to 12 and 13, so that doesn't count. The one with the months doesn't have any x values with more than one y value, so it is a function.

mrs smith baked 40 turnovers. Her son ate 1/8 of the turnovers and her husband ate 1/7 of what was left. How many were left afte

snow_tiger [21]

The answer is 30 because 1/8 of 40 is 5 so 40-5 = 35 and 1/7 of 35 is 5 so 35-5 = 30

A playground is being designed where children can interact with their friends in certain combinations. If there is 1 child, ther

<h2>Answer:</h2>

Recursive equation for the pattern followed is given by,

$a_{n}=a_{n-1}+(n-1)^{2}$

<h2>Step-by-step explanation:</h2>

In the question,

The number of interaction for 1 child = 0

Number of interactions for 2 children = 1

Number of interactions for 3 children = 5

Number of interaction for 4 children = 14

So,

We need to find out the pattern for the recursive equation for the given conditions.

So,

We see that,

$a_{1}=0\\a_{2}=1\\a_{3}=5\\a_{4}=14\\$

Therefore, on checking, we observe that,

$a_{n}=a_{n-1}+(n-1)^{2}$

On checking the equation at the given values of 'n' of, 1, 2, 3 and 4.

At,

n = 1

$a_{n}=a_{n-1}+(n-1)^{2}\\a_{1}=a_{1-1}+(1-1)^{2}\\a_{1}=0+0=0\\a_{1}=0$

which is true.

At,

n = 2

$a_{n}=a_{n-1}+(n-1)^{2}\\a_{2}=a_{2-1}+(2-1)^{2}\\a_{2}=a_{1}+1\\a_{2}=1$

Which is also true.

At,

n = 3

$a_{n}=a_{n-1}+(n-1)^{2}\\a_{3}=a_{3-1}+(3-1)^{2}\\a_{3}=a_{2}+4\\a_{3}=5$

Which is true.

At,

n = 4

$a_{n}=a_{n-1}+(n-1)^{2}\\a_{4}=a_{4-1}+(4-1)^{2}\\a_{4}=a_{3}+9\\a_{4}=14$

This is also true at the given value of 'n'.

Therefore, the recursive equation for the pattern followed is given by,

$a_{n}=a_{n-1}+(n-1)^{2}$

Can someone just explain to me how to do this please

Dmitrij [34]

Answer: -7.5

Step-by-step explanation:

area = 1/2bh.

area = 1/2(x+6)(5)

area = x/2 + 15

area = x/2 = -15

area = x = -7.5

area = -7.5

Answer:

89°

Step-By-Step Explanation:

<WYT is the angle 4

<UYW is the angle 5

since angle 4 and 5 are on the same line and

anngle 4 is 91°,

180° - 91° = 89°

This shows that <UYW is 89°

If this helped, please consider picking this answer as the Brainliest Answer. Thank you!
