Mark recorded the growth of a plant over 8 weeks. The equation y=0.2x+2 represents the height y, in inches, after x weeks.
klio [65]

Answer:

Step-by-step explanation:

The equation representing the growth of the plant after x weeks is expressed as

y = 0.2x+2

Where

x represents the number of weeks.

y represents the height of the plant after x weeks in inches.

A.

The height of the plant after week 3 was about 2.6 inches. We can check by substituting x = 3 into the equation. It becomes

y = 0.2 × 3 + 2 = 2 + 0.6 = 2.6 inches. It is correct.

B is incorrect.

C.

The height of the plant after week 9 was about 3.8 inches. We can check by substituting x = 9 into the equation. It becomes

y = 0.2 × 9 + 2 = 2 + 1.8 = 3.8 inches. It is correct.

D is incorrect

Island A is 150 miles from Island B. A ship captain travels 310 miles from Island A and then finds that he is off course and 200
wolverine [178]

Answer:

156.37°

Step-by-step explanation:

We solve this above question, using Cosine rule which is given as:

Cos C = a² + b² - c²/2ab

Let the Angle be represented as: x

Cos x = 310² + 200² - 150²/2 × 310 × 200

x = arc cos [ 310² + 200² - 150²/2 × 310 × 200]

x = 23.63°

The angle, in degrees, that he must turn through to head straight for Island B is given as:

180° - 23.63°

= 156.37°

there are 36 roses and 27 carnations. anna is making flower arrangements using both flowers, if she made the maximum number of a
solniwko [45]
This is a GCF problem,
find the GCF of 36 and 27. To do this, list out the factors for each number.
EX 36- 1×36, 2×18, so on and so on. Then do this for 27. The GCF will be the greatest factor. In this case, that is 9.
So there would be 9 groups because that is the greatest common factor.
there would be 4 roses in each group because 4×9= 36.
There are 3 carnations in each group because 9×3 =27.
So 9 groups with 4 roses and 3 carnations.
