The area of a square is 214 square yards. Which best represents the length of a side? ​
irinina [24]

Answer:

The length and width of square is same .Therefore the sides of square can be found by taking the square root of area.

Step-by-step explanation:

• Area of square is = 214 square yards.

• To find the side ,we have to take the square root of area therefore

& s=\sqrt{214} \\  & s=14.6 \\

 • Hence, side of square is 14.6 yards.

Gwen, Tristan and Keith like to work out at the gym . They each have an app on their phone that estimates the calories they burn
Anarel [89]

Based on the above scenario, an equation that shows how much Gwen paid. The equation for Gwen is y = 100 + 10x

  • The equation for Tristan is y = 12.5x
  • The equation for Keith is y = 10x.

<h3>What is the  equation  about?</h3>

Since Gwen burns  about 10 cal/min. THen she had used up 100 calories if Tristan and Keith began ar (Y g=100 if  x=0)

Then Y(g)= 10x + 100

Since Tristan is known to burns 125 cal in 10 minutes always, then one can write her own as 12.5 cal every minute.

Therefore Y (t) = 12.5x

Since Keith burns 300 calories in 30 min always, or 10 calories in every minute.

Then Y (k) = 10x

The   general function of y:

y=10x +100 + 12.5x + 10x

y = 32.5x + 100

Therefore, Based on the above scenario, an equation that shows how much Gwen paid. The equation for Gwen is y = 100 + 10x

  • The equation for Tristan is y = 12.5x
  • The equation for Keith is y = 10x.

Use truth tables to show that the following statements are logically equivalent. ∼ P ⇔ Q = (P ⇒∼ Q)∧(∼ Q ⇒ P)
Alina [70]

Answer:  The given logical equivalence is proved below.

Step-by-step explanation:  We are given to use truth tables to show the following logical equivalence :

∼ P ⇔ Q ≡ (P ⇒∼ Q)∧(∼ Q ⇒ P)

We know that

two compound propositions are said to be logically equivalent if they have same corresponding truth values in the truth table.

The truth table is as follows :

P     Q     ∼ P     ∼Q   ∼ P⇔ Q    P ⇒∼ Q    ∼ Q ⇒ P     (P ⇒∼ Q)∧(∼ Q ⇒ P)

T     T         F        F             F            F                   T                       F

T     F         F        T             T             T                   T                       T

F     T         T        F             T            T                   T                       T

F     F         T        T             F            T                   F                       F

Since the corresponding truth vales for ∼ P ⇔ Q and (P ⇒∼ Q)∧(∼ Q ⇒ P) are same, so the given propositions are logically equivalent.

Thus, ∼ P ⇔ Q ≡ (P ⇒∼ Q)∧(∼ Q ⇒ P).
