Clevon forms a triangle with three straws measuring 20, 25, and 18 inches. To the nearest whole

Ne4ueva [31]

Answer:

Step-by-step explanation:

Let's label this triangle as triangle ABC. Side AB is 18, side BC is 20 and side CA is 25 and the angle we are looking for is angle C. Use the Law of Cosines to find the missing angle. You have to use the Law of Cosines because in order to use the Law of Sines you have to have an angle given and we don't so we have no other options. In our case,

$c^2=a^2+b^2-2abcosC$ which for us looks like this:

$18^2=20^2+25^2-2(20)(25)cosC$ and

$324=400+625-1000cosC$ and

$324=1025-1000cosC$ and

$-701=-1000cosC$ and

$.701=cosC$

Use the 2nd button and the cos button to find the missing angle.

Angle C = 45.4 which is, rounded to the nearest degree, 45°

5p - 14 = 8 p + 4 No solution, Infinitely many solutions, 6 ,-6

DedPeter [7]

Answer:

-6

Step-by-step explanation:

5p - 14 = 8p + 4

Subtract 8p from both sides.

-3p - 14 = 4

Add 14 to both sides.

-3p = 18

Divide both sides by -3.

p = -6

Answer: -6

Use the rules of negative numbers to calculate -6 + -6 - -2

yaroslaw [1]

-6+ -6- -2
Adding a negative is the same as subtracting a positive.
-6 - 6 - -2
Subtracting a negative is the same as adding a positive.
-6 - 6 + 2
Subtracting a number from a negative number is like adding the positive numbers, just remember to put the negative sign in front of the number.
-12 + 2
Adding a positive number to a negative number is like subtracting a positive from another positive, but don't forget the negative sign when you're done.
-12 +2 = -10

The graph shows the relationship between time

jekas [21]

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

$(\stackrel{x_1}{4}~,~\stackrel{y_1}{64})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{96}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{96}-\stackrel{y1}{64}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{4}}}\implies \cfrac{\stackrel{bottles}{32}}{\underset{mins}{2}}\implies \cfrac{\stackrel{bottles}{16}}{\underset{mins}{1}}$
