Which input value produces the same output value for the two functions on the graph
Mademuasel [1]

Answer:

The input value is x=1

Step-by-step explanation:

we know that

The intersection point both graphs is the point that  produces the same output value for the two functions

Observing the graph

The intersection point is (1,1)

therefore

For x=1 (input value)

The output value for the two functions is equal to 1

What postulate or theorem can be used to prove that these two triangles are congruent?
kati45 [8]

Answer:

AAS postulate can be used to prove that these two triangles are congruent

Step-by-step explanation:

Let us revise the cases of congruence  

  1. SSS ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ
  2. SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and including angle in the 2nd Δ
  3. ASA ⇒ 2 angles and the side whose joining them in the 1st Δ ≅ 2 angles and the side whose joining them in the 2nd Δ
  4. AAS ⇒ 2 angles and one side in the 1st Δ ≅ 2 angles and one side in the 2nd Δ
  5. HL ⇒ hypotenuse and leg of the 1st right Δ ≅ hypotenuse and leg of the 2nd right Δ  

In the given figure

∵ There is a pair of vertically opposite angles

∵ The vertically opposite angles are congruent ⇒ (1)

∵ There are two angles have the same mark

∴ These marked angles are congruent ⇒ (2)

∵ There are two sides have the same mark

∴ These two marked sides are congruent ⇒ (3)

→ From (1), (2), and (3)

∴ The two triangles have 2 angles and 1 side congruent

→ By using case 4 above

∴ The two triangles are congruent by the AAS postulate of congruency.

AAS postulate can be used to prove that these two triangles are congruent

Find the missing side lengths leave your answerss as radicals
Sunny_sXe [5.5K]

Answer:

x = 8, y = 4

Step-by-step explanation:

To find x use the sine ratio in the right triangle and the exact value

sin60° = \frac{\sqrt{3} }{2} , thus

sin60° = \frac{opposite}{hypotenuse} = \frac{4\sqrt{3} }{x} = \frac{\sqrt{3} }{2} ( cross- multiply )

x × \sqrt{3} = 8\sqrt{3} ( divide both sides by \sqrt{3} )

x = 8

--------------------------------------------------------------

To find y use the tangent ratio in the right triangle and the exact value

tan60° = \sqrt{3} , thus

tan60° = \frac{opposite}{adjacent} = \frac{4\sqrt{3} }{y} = \sqrt{3} ( multiply both sides by y )

4\sqrt{3} = y × \sqrt{3} ( divide both sides by \sqrt{3} )

y = 4

Which of the following is the best buy? a 16 oz bag of rice for $2.42 a 12 oz box of rice for $1.93 a 6 oz box of rice for 90¢ a
Marina CMI [18]
12 oz box o rice divided by 1.93 = 16 cents per oz
6 oz box o rice divided by .90 = 15 cents per oz
9 oz box o rice divided by 1.25 = 13 cents per oz.
The third option is the most cheapest.
Hope this helps!!!
