He is wrong. we are only looking at the last number which is 4
if we tripple 4 or 4*3 we get 12 which ends in 2, not 9

Answer:

P' = (3, -5)

Step-by-step explanation:

Rotation 180° about the origin is the same as reflection across the origin. The transformation is given by ...

(x, y) ⇒ (-x, -y) . . . . . . the signs of the coordinates are both changed

P(-3, 5) ⇒ P'(3, -5)

While evan and sam are fishing 12kms from shore, their boat springs a leak, and water comes in at a constant rate of 3 gallons p

aev [14]

Based on the calculations, the slowest rate is equal to 4 gallons per minute.

<u>Given the following data:</u>

Distance from shore = 12 km.

In-rate = 3 gallons per minute.

Rowing rate = 24 km per hour.

<h3>How to calculate the slowest rate.</h3>

Let's assume the boat would sink if it takes in more than 20 gallons of water.

<u>Conversion:</u>

24 km/h to km/min = $\frac{24 }{60}$ = 0.4 km/min.

Translating the word problem into an algebraic expression, we have;

$\frac{12}{0.4} \times 3 - \frac{12}{0.4} \times x\geq 30\\\\\frac{36}{0.4}-\frac{12x}{0.4} \geq 30\\\\90-\frac{12x}{0.4} \geq 30\\\\\frac{12x}{0.4} \geq90+30\\\\\frac{12x}{0.4} \geq120\\\\12x \geq120 \times 0.4\\\\12x \geq 48\\\\x\geq 4$

Therefore, the slowest rate is equal to 4 gallons per minute.

Answer:

Hey! Ok so the answer is B. Geometric

Step-by-step explanation:

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 5 gives the next term.

Hope you have a great day! I'm Eve btw Hoped this helped and consider marking this brainiest thanks so much if you do!
