Answer:

The numbers are 7, (-6)

Step-by-step explanation:

Let one number be x

So, other number = 1 - x  

x*(1 -x) = -42

x - x²   = -42

0 = -42 -x +x²

x² - x - 42 = 0

x² + 6x - 7x - 7*6 = 0

x(x + 6) -7 (x + 6) = 0

(x + 6)(x - 7) = 0

x + 6 = 0    ; x - 7 =0

x = -6         ; x = 7

The numbers are 7, (-6)

Compare a dilation to the other transformations: translation, reflection, rotation.
inysia [295]

Answer:

We know that there are four types of rigid transformations namely Dilation, Translation, Reflection and Rotation.

Now, Dilation is the transformation that changes the size of the figure by some scale factor i.e. it is the transformation that increases or decreases the size of the given figure.

We can see in the first figure that the triangle ABC is dilated ( increased by some scale factor ) to form A'B'C'.

Further, Translation is the transformation that slides the figure horizontally or vertically to a fixed distance.

The second figure shows the change of position of the solid ABCD to the position of A'B'C'D'.

Now, Reflection is the transformation that flips the image about a straight line.

During reflection, the size of the figure remains same but the it goes to the opposite side of the line.

We can see from the third figure the reflection of ABC about the y-axis to form A'B'C'.

Finally, Rotation is the transformation that turns the image about a fixed point called the center of rotation to a certain degree.

So, in the last figure, we see that the image A is rotated about the center of rotation by 120° to form A'.

Hence, we see that Dilation is different from the other transformations.

A credit card had an APR of 14.86% all of last year, and compounded interest
hoa [83]

We have been given that a credit card had an APR of 14.86% all of last year, and compounded interest  daily. We are asked to find the effective interest rate of the credit card.

We will use effective interest rate formula to solve our given problem.\text{Effective rate}=(1+\frac{r}{m})^n-1, where

r = Annual interest rate in decimal form,

m = Number of times interest is compounded per year,

n = Number of compounding periods the rate is required for.

14.86\%=\frac{14.86}{100}=0.1486

We need rate for 1 year, so n will be 365 times 1.

\text{Effective rate}=(1+\frac{0.1486}{365})^{365\cdot 1}-1

\text{Effective rate}=(1+0.0004071232876712)^{365}-1

\text{Effective rate}=(1.0004071232876712)^{365}-1

\text{Effective rate}=(1.1601737274495528201)-1

\text{Effective rate}=0.1601737274495528201

Let us convert effective rate in percent.

0.1601737274495528201\times 100\%=16.01737274495528201\%\approx 16.02\%

Therefore, the effective interest rate would be 16.02\%.
