Mark recorded the growth of a plant over 8 weeks. The equation y=0.2 x+2

Mathematics
1 answer:
Leto [7]3 years ago

Answer:

A. The height of the plant after week 3 was about 2.6 inches.

C. The height of the plant after week 9 was about 3.8 inches.

Step-by-step explanation:

The equation given:

Y = 0.2x + 2

x represents the number of weeks

substituting x = 3 into the equation , we will have

y = 0.2(3) + 2

y = 0.6 + 2

y = 2.6

This means that  the height of the plant after week 3 was about 2.6 inches.

Also , substituting x = 9 into the equation will give

y = 0.2 (9) + 2

y = 1.8 + 2

y = 3.8

This means that the height of the plant after week 9 was about 3.8 inches.

Jet001 [13]

Answer:

A is f ", B is f, C is f '.

Step-by-step explanation:

Your answer is correct.  B is the original function f.  It has a local maximum at x=0, and local minimums at approximately x=-3/2 and x=3/2.

C is the first derivative.  It crosses the x-axis at each place where B is a min or max.  C itself has a local maximum at approximately x=-3/4 and a local minimum at approximately x=3/4.

Finally, A is the second derivative.  It crosses the x-axis at each place where C is a min or max.

One angle of an isosceles triangle measures 26°. Which other angles could be in that isosceles triangle?
Julli [10]

Answer:

There are two answers, either of which would work

  • 26°, 26° and 128°
  • 26°, 77° and 77°

Method:

An isosceles triangle has 2 of the same sides so there are two possible answers:

1) 26° is one of the angles which is the same as another. 26° × 2 = 52° and since there are 180° in a triangle the other angle is 180° - 52° which is 128°. This would make the angles 26°, 26° and 128°

2) 26° is not one of the angles which is the same as another. Since there are 180° in a triangle, the other angles would both be 2 ÷ (180° - 26°) which is 77°. This would make the angless 26°, 77° and 77°

The diagram shows a circle with center C, a diameter RS, and an inscribed triangle RST.
snow_tiger [21]

Answer:

x = 26

Step-by-step explanation:

m<RTS = 4x - 14 (given)

Based on the inscribed angle theorem, the measure of the inscribed angle in a semicircle = right angle (90°)

Therefore,

4x - 14 = 90

4x - 14 + 14 = 90 + 14 (addition property of equality)

4x = 104

4x/4 = 104/4

x = 26
