Writethecoordinatesoftheverticesafteradilationwithascalefactorof 1 5 ,centeredattheorigin. y x -10 10 -10 10 0 S T U S(5, -10) →
densk [106]

Answer:

The answer is below

Step-by-step explanation:

Write the coordinates of the vertices after a dilation with a scale factor of 1/5 , centered at the origin.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.

Dilation is the reduction or enlargement in the size of an object by a scale factor (k). If k > 1, it is an enlargement and if k < 1, it is a reduction. If a point A(x, y) is dilated by a factor k, the new point is A'(kx, ky).

Therefore, if the vertices are dilated with a scale factor of 1/5 , centered at the origin. The new point is:

S(5, -10) → S′(1 , -2) T(10, -10) → T′(2 , -2) U(5, 10) → U′(1 , 2)

What is the range of the function y=cot(x)?
dimulka [17.4K]

Answer:

(−∞,+∞)

Step-by-step explanation:

The cotangent function can take up any values depending on the value of

x

, the independent variable.

And thus, the range

(

−

∞

,

+

∞

)

is justified.

The domain is all real numbers other than integral multiples of

π

where, the function is not defined.

Becky purchased a home entertainment center for $2,254 using an 18-month deferred payment plan with an interest rate of 22.48%.
Anna [14]

Answer:

$76.69

Step-by-step explanation:

Purchase price = $2254

Interest rate on purchase = 22.48% = 0.2248

Payment time-line = 3 years = (3 * 12) = 36 months

To calculate the Monthly payment :

Total amount to be paid = (Purchase price + interest on the purchase price)

Total amount to be paid :

2254 + (0.2248*2254) = 2760.6992

Monthly payment :

Total amount / number of months

2760.6992 / 36

= 76.686088

= $76.69

A shipping company claims that 90% of its packages are delivered on time. Jenny noticed that out of the last 10 packages shipped
Gnoma [55]

Answer:

The probability is;

0.0000003645

Step-by-step explanation:

The probability of packages being early p is 90% = 0.9

The probability of packages being late q will be 1-p = 1-0.9 = 0.1

So the probability of 2 out of 10 random late will be subject to Bernoulli approximation of the Binomial theorem

That will be;

P(X = 2) = 10 C 2 0.9^2 0.1^8

= 0.0000003645
