Answer:

#11

<u>Complementary angles ad to 90°</u>

  • b = 90° - 65° = 25°

#12

<u>Alternate exterior angles are congruent</u>

  • b = 60°

#13

<u>Complete angle and angle addition postulate</u>

  • b = 360° - (244° + 23°) = 93°

#14

<u>Vertical angles are congruent</u>

  • b = 46°

#15

<u>Complementary angles add to 90°. Straight angle is 180°</u>

  • b = (180° - 90°) - 39° = 51°

#16

<u>Alternate interior angles are congruent</u>

  • b = 85°

Answer:

u=\frac{9}{t}-\frac{1}{2} a t

Step-by-step explanation:

Step 1: Given equation: 9=\frac{1}{2} a t^{2}+u t

To get u, by subtraction equality property subtract both sides of the equation by  \frac{1}{2} a t^{2}.

\Rightarrow 9-\frac{1}{2} a t^{2}=\frac{1}{2} a t^{2}+u t-\frac{1}{2} a t^{2}  

\Rightarrow 9-\frac{1}{2} a t^{2}=u t  

Step 2: By division equality property, divide both sides of the equation by t.

\Rightarrow \frac{9-\frac{1}{2} a t^{2}}{t}=\frac{u t}{t}

$\Rightarrow \frac{9}{t}-\frac{1}{2} a t=u$  

Therefore, $u=\frac{9}{t}-\frac{1}{2} a t$.

So, in Emily’s physics class, she got $u=\frac{9}{t}-\frac{1}{2} a t$.

What is represented by p v q?
Stella [2.4K]
\lor is the logical or/disjunction symbol. p\lor q means "p or q". Disjunction is commutative, which means p\lor q is equivalent to q\lor p.

So if p represents x and q represents x>3, then p\lor q\equiv q\lor p means x>3 or x.
