OK.

Let g(x) = ax²

We have the point (3, 1).

Substitute x = 3 and g(x) = 1:

1 = a(3²)

9a = 1    |divide both sides by 9

a = 1/9

Therefore your answer is

g(x)=\dfrac{1}{9}x^2=\left(\dfrac{1}{3}x\right)^2

The box-and-whisker shows the average monthly temperatures in Mathville.
Andrei [34K]

Answer:

50

Step-by-step explanation:

The range is 50 because the maximum number is 90 and you subtract that from 40 which gives you 50.

90= maximum

40= minimum

90-40=50

What is the measure of arc KL?<br><br> 20°<br> 40° <br> 48° <br> 96°
mash [69]

The question is incomplete. The complete question is here

Angle KJL measures (7x - 8)° and angle KML measures (3x + 8)°. What is the measure of arc KL, if M and J lie on the circle ?

Answer:

The measure of arc KL is 40° ⇒ 2nd answer

Step-by-step explanation:

In any circle:

  • Inscribed angles subtended by the same arc are equal
  • If the vertex of an angle lies on the circles and its two sides are chords in the circle, then it called inscribed angle
  • The measure of an inscribed angle is equal to half the measure of its subtended arc

In a Circle

∵ M lies on the circle

∵ KL is an arc in the circle

∴ MK and ML are chords in the circle

∴ ∠KML is an inscribed angle subtended by arc KL

∵ J lies on the circle

∵ KL is an arc in the circle

∴ JK and JL are chords in the circle

∴ ∠KJL is an inscribed angle subtended by arc KL

∵ Inscribed angle subtended by the same arc are equal

∴ m∠KML = m∠KJL

∵ m∠KML = (3x + 8)°

∵ m∠KJL = (7x - 8)°

- Equate them to find x

∴ 7x - 8 = 3x + 8

- Subtract 3x from both sides

∴ 4x - 8 = 8

- Add 8 to both sides

∴ 4x = 16

- Divide both sides by 4

∴ x = 4

- Substitute the value of x in the m∠KML OR KJL to find its measure

∵ m∠KML = 3(4) + 8 = 12 + 8

∴ m∠KML = 20°

∴ m∠KJL = 20°

∵ The measure of an inscribed angle is equal to half the measure

   of its subtended arc

∴ m∠KML = \frac{1}{2} (m of arc KL)

∵ m∠KML = 20°

∴ 20 = \frac{1}{2} (m of arc KL)

- Multiply both sides by 2

∴ 40° = m of arc KL

The measure of arc KL is 40°

Each box holds 6 shirts
there are 45 shirts

45/6 = 7.5

Since you need a full box to fit the shirts, you will need 8 boxes

8 boxes is the least amount the clerk can use to store the shirts
