Enlarge the triangle by scale factor 0.5 using 3,1 as the centre of enlargement

Mathematics
1 answer:
BARSIC [14]2 years ago
5 0

Answer:(0,0) (-1,0) (-1,3)

Step-by-step explanation:

scf 0.5 is shrinking the shape by a 1/2

The coordinates of a point of enlargment is (3,1)

so you work out the vectors of each corner than times it by 0.5

The vector of one cooridnate is (-6 -2)

-6x0.5=-3

-2x0.5=-1

so the vector is -3 -1 from the point of enlargment is the shape .

(-8 -2 ) is the coodinates of the next vector so

(-4 -1)

Then the last

(-8, 4)

(-4,2) vector for the last coodinate

sorry i couldn't write out the vector properly in the right notation .

Answer:

You'll likely need assets worth 10 to 16 times your salary by the time you leave your job. A 45-year-old making $120,000 who hopes to retire at age 60, say, should already have nearly $700,000 set aside. (See the Retire Early calculator.) You can get by with less if you'll have other sources of income.

What is the average rate of change for this quadratic function for the interval
stealth61 [152]
<h3>Answer:   -4  (choice B)</h3>

==========================================================

Explanation:

The table says that when x = 1, the output is y = -2.

So the point (1, -2) is on the parabola.

The table also says that point (3, -10) is on the parabola. We're focusing on this because x = 3 is the other endpoint.

Find the slope of the line through those two points. The slope here is the same as the average rate of change.

m = (y2 - y1)/(x2 - x1)

m = (-10 - (-2))/(3 - 1)

m = (-10 + 2)/(3 - 1)

m = -8/2

m = -4 is the slope, and therefore, the average rate of change from x = 1 to x = 3.

According to the same report, the 28.5 million passengers in 2018 represented a 6.7% increase in cruise passengers since 2017. h
Alisiya [41]

The number of cruise passengers must there have been in 2017 is  26.7 million.

<h3>What is percentage?</h3>

The term "percentage" comes from the Latin phrase "per centum," meaning "by the hundred." Percentages represent fractions with a denominator of 100. In other terms, it is the relationship between portion and whole in which the value of the whole is always assumed to be 100.

Now according to the question;

Let x represent the total number for cruise passengers during 2017.

In 2018, a 6.7% rise in x results in 28.5 million cruise passengers.

So, 106.7 % of x = 28.5

\begin{aligned}&\frac{106.7}{100} * x=28.5 \\&\frac{106.7 x}{100}=28.5\end{aligned}

Multiplying both sides by 100;

\begin{aligned}&\frac{106.7 x}{100} * 100=28.5 * 100 \\&106.7 x=2850\end{aligned}

Dividing both sides by 106.7;

\frac{106.7 x}{106.7}=\frac{2850}{106.7}

x = 26.7

Therefore, the number of cruise passengers in 2017 must have ranged from 26.7 million.
