A biologist is tracking the path of a bird. The bird flies from point A to point B on the map. What vector can be used to expres
lawyer [7]

Answer:

c = -5

d = -10

Step-by-step explanation:

A biologist is tracking a bird when it was at A.

Coordinates of point A are (2, 4).

This bird moves from point A to point B.

Coordinates of the point B are (-3, -6).

Vector form of vector represented by \overrightarrow{AB}=

By substituting the coordinates of points A and B,

\overrightarrow{AB}=

      = < -5, -10 >

\overrightarrow{AB}=\binom{-5}{-10}

By comparing it with the vector form of [cd]

c = -5

d = -10

Bob and Mark talk about their families. Bob says he has 3 kids, the product of their ages is 72. He gives another clue: the sum
DaniilM [7]
I have answered this question before. 

Given:
Bob has three kids whose ages has the product of 72. I will only be able to give you a set of 3 numbers to represent the ages. Had the sum of the ages been given, the specific ages would be provided.

I just did a prime factorization of 72.

72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 =   9
  9 ÷ 3 =   3
  3 ÷ 3 =   1

1 x 2 x 2 x 2 x 3 x 3 = 72   ⇒ 2³ x 3²

There are a lot of possible combinations, here are a few.

1 x 8 x   9 = 72      ⇒ 1 + 8 + 9 = 18
1 x 4 x 18 = 72      ⇒ 1 + 4 + 18 = 23
<span>2 x 4 x   9 = 72      ⇒ 2 + 4 + 9 = 15</span>

Jeremy completes eight extra credit problems on the first day and then for problems each day until the work is complete their 28
Novay_Z [31]

I THINK there is a typo. Instead of "for problems each day", i think it's "four problems each day."

Anyway, we need to find how many days it takes Jeremy to complete the paper.

If he completes 8 problems on the first day and 4 on the rest of the days, after the first day he'll have 28 - 8 = 20 more problems.

And since he does 4 every day with 20 problems: 20 / 4 = 5 days.

A consultant built an Einstein Analytics dashboard for a shipping company. The dashboard displays data from several data sources
anzhelika [568]

Answer: A (30)

Step-by-step explanation:

By defaults, data will be enabled in tens. And it increases by replicating the initial value.

There is no way the maximum number of dataflow definitions available in this situation will be 45, 25 or 35

The only possible replicant that can be available is 30
