Answer:

603 miles in 3 days

Step-by-step explanation:

Let's find out how many miles in 1 day:

  1. 1,005 ÷ 5 = 201
  2. So, Sarah drives 201 miles in 1 day

Let's find out how many miles in 3 days:

  1. 3 days = 1 day × 3
  2. 3 days = 201 × 3
  3. 3 days = 603 miles

I hope this helps!

Use the dot product to determine which of the following vector pairs are orthogonal.
Vika [28.1K]

ANSWER

a) Orthogonal

b) Not orthogonal.

EXPLANATION

The given vectors are:

a)

v1 = \:   <  \:  - 5,5 \:  >

and

v2= \:   <  \:  1,1 \:  >

If the dot product of two vectors is zero, then the two vectors are orthogonal.

v1  \bullet \: v2=  - 5 \times 1 + 5 \times 1

v1  \bullet \: v2=  - 5 \times 1 + 5 \times 1  =  - 5 + 5

v1  \bullet \: v2=  0

These two vectors are orthogonal.

b)

The second pair of vectors are:

v1 = \:   <  \:  154, -169.4 \:  >

and

v2 = \:   <  \:  88,64 \:  >

v1  \bullet \: v2=  154\times 88 +  - 169.4\times 64

v1  \bullet \: v2=  13552 - 10841.6

v1  \bullet \: v2=  2712.4

This pair is not orthogonal.

Select all factors of the following polynomial: 5p3 + 45p2 + 40p<br><br>​
madam [21]

Answer:

\huge\boxed{5p;\ (p+1)}

Step-by-step explanation:

5p^3+45p^2+40p=5p(p^2+9p+8)=5p(p^2+p+8p+8)\\\\=5p\bigg[p(p+1)+8(p+1)\bigg]=5p(p+1)(p+8)\\\Downarrow\\\boxed{5p};\ \boxed{(p+1)};\ \boxed{(p+8)}
