Answer:

Step-by-step explanation:

Given the sequence :

23, 19, 13, 5, -5.......

From the sequence, the common difference is unequal, as their is a constant Increment in the difference after successive numbers.

19 - 23 = -4

13 - 19 = -6

5 - 13 = -8

-5 - 5= -10

Hence an constant difference of - 2 after each successive difference.

Hence, this is a quadratic sequence

With the formula

an² + bn + c

Answer:

Well, at least you improved. But maybe you should use another source besides brainly for your tests. Sometimes people put the wrong answers just to get points.

I hope you do better next time! Good luck!!

Answer:

Step-by-step explanation:

First do, 30% + 45% = 75%. Then do, 100-75=25.

Lastly,

proportions:

x/60 = 25/100

So your answer is, 15.

Look at the picture of a scaffold used to support construction workers. The height of the scaffold can be changed by adjusting t

Step-by-step explanation:

<u>Using Pythagorus theorem</u> :

(A)

$PR = \sqrt{ {PQ}^{2} + {QR}^{2} }$

$PR = \sqrt{196 + 81} = \sqrt{277} = 16.64 \: cm$

(B)

$QR = \sqrt{ {PQ}^{2} + {PR}^{2} } = \sqrt{196 +324 } = 22.8 \: cm$

A movie theater is 10 blocks north and 5 blocks east of a post office. A mall is 7 blocks north and 9 blocks east of the post of

MAXImum [283]

The complete question required that we determine how far is the movie theater to the mall.

<h3>Distance between the movie theatre and the mall </h3>

According to the question;

Upon representation of the movie theatre and mall position on the coordinate plane relative to the post office; we have;

Movie theater, T = (5, 10)
Mall, M = (9, 7).

The distance between the two points can therefore be evaluated by Pythagoras theorem as follows;

Distance, D² = (9-5)² + (7-10)²

D² = 4² + (-3)²

D² = 16 + 9

D² = 25

D = √25 = 5 blocks.

Ultimately, the movie theater is 5 blocks away from the mall.
