Answer:
The image of the point is (-27, 6)
Step-by-step explanation:
<em>Let us talk about the dilation</em>
- Dilation is a transformation that changes the size of a figure. It can become larger or smaller, but the shape of the figure does not change.
- The scale factor of dilation measures how much larger or smaller the image will be. If the scale factor greater than 1, then the image will be larger. If the scale factor between 0 and 1, then the image will be smaller
- If the point (x, y) is dilated by scale factor k and the center of dilation is the origin, then its image will be (kx, ky)
∵ Point (-9, 2) is dilated by a scale factor 3
∴ k = 3
∵ The center of dilation is the origin
→ Multiply the coordinates of the point by 3 to find the image
∴ The image = (3 × -9, 3 × 2)
∴ The image = (-27, 6)
The image of the point is (-27, 6)
Answer:
1
Step-by-step explanation:
The function with the given zeros will factor as ...
f(x) = a(x +15)(x^2 +9) . . . . with leading coefficient 'a'
You have ...
f(2) = 221 = a(2+15)(2^2+9) = a(17)(13) = 221a
Then a = 221/221 = 1
The leading coefficient is 1.

<em>Additional comment</em>
As you know, a function with zero x=p has a factor of (x -p). The given zeros mean the function has factors (x -(-15)), (x -3i). and (x -(-3i)). The product of the last two factors is the difference of squares: (x^2 -(3i)^2) = (x^2 -(-9)) = (x^2 +9). This is how we arrived at the factorization shown above.
70 ounces or 4.375 Pounds. (They weigh the same)
Explanation:
First off all, lets convert everything to improper fractions. Two pounds converted into a fraction would be 2/1. 1 3/4 would be 7/4. After converting the fractions of pounds, we add them. 2/1 + 7/4. Since they have different denominators, we have to find the Lowest Common Multiple which would be 4. Leave the right side alone and multiply 4 to your left denominator and numerator. That would leave you with 8/4 + 7/4. Adding them up, you would get 15/4. Divide that, and you should get 3 3/4 Pounds. Convert that into ounces. (16 ounces = 1 Pound) and you should get 60 ounces. Add the 10 ounces from the sentence and you should get 70 ounces
