Answer:
173.9
Step-by-step explanation:
9.40 × 18.5 = 173.9.
The average ladybug is about 1 cm long, but it is more accurate to measure in millimeters.
Correct question is;
Tanya walked for 17 minutes from her home to a friend that lives 1.5 kilometers away. D(t) models Tanyas remaining distance to walk in kilometers, t minutes since she left home. What number type is more appropriate for the domain of d?
Answer:
0 ≤ t ≤ 17 ; (0, 17)
Step-by-step explanation:
We are told that she has walked for 17 minutes from her home to a friend that lives 1.5 kilometers away.
Now, we want to find the domain of numbers that shows her remaining distance.
Since she spent 17 minutes, then it means in modeling remaining distance it could be from 0 to 17 minutes as the case may be. Thus, the domain can be written as;
0 ≤ t ≤ 17 ; (0, 17)
Answer:
a) factors of polynomial are: (x+1)(x-2)(x-5)
b) the required polynomial in standard form is: ![\mathbf{x^3-6x^2+3x+10}](https://tex.z-dn.net/?f=%5Cmathbf%7Bx%5E3-6x%5E2%2B3x%2B10%7D)
Step-by-step explanation:
The polynomial has zeros at -1,2,5
Part A) Write the three factors of the polynomial
we have x=-1, x=2 and x=5 as zeros of polynomial
so factors will be:
(x+1)=0, (x-2)=0, (x-5)=0
So, factors of polynomial are: (x+1)(x-2)(x-5)
Part B) Write the polynomial in standard form
For finding polynomial, we will multiply all the factors i.e
(x+1)(x-2)(x-5)
![(x+1)(x-2)(x-5)\\=(x(x-2)+1(x-2))(x-5)\\=(x^2-2x+x-2)(x-5)\\=(x^2-x-2)(x-5)\\=x(x^2-x-2)-5(x^2-x-2)\\=x^3-x^2-2x-5x^2+5x+10\\=x^3-x^2-5x^2+5x-2x+10\\=x^3-6x^2+3x+10](https://tex.z-dn.net/?f=%28x%2B1%29%28x-2%29%28x-5%29%5C%5C%3D%28x%28x-2%29%2B1%28x-2%29%29%28x-5%29%5C%5C%3D%28x%5E2-2x%2Bx-2%29%28x-5%29%5C%5C%3D%28x%5E2-x-2%29%28x-5%29%5C%5C%3Dx%28x%5E2-x-2%29-5%28x%5E2-x-2%29%5C%5C%3Dx%5E3-x%5E2-2x-5x%5E2%2B5x%2B10%5C%5C%3Dx%5E3-x%5E2-5x%5E2%2B5x-2x%2B10%5C%5C%3Dx%5E3-6x%5E2%2B3x%2B10)
So, the required polynomial in standard form is: ![x^3-6x^2+3x+10](https://tex.z-dn.net/?f=x%5E3-6x%5E2%2B3x%2B10)
With no much there it is hard to answer this.
But I am pretty sure I was able to do it
It’s call :
Simplify the matrix.
you have to write it out in the same [ ] [ ] large boxes as the picture you added
Top roll [ -5 -4 ]
Bottom roll. [ -5 -10] + a = b =
