Answer:

<h3>x = 4</h3>

Step-by-step explanation:

102 + 102 + 24x + 24x - 18 - 18 = 360

204 + 48x - 36 = 360

204 + 48x = 360 + 36

204 + 48x = 396

48x = 396 - 204

48x = 192

x = 192/48

x = 4

The diagram shows the curve with equation y = ( 1 + x ) cosx.
r-ruslan [8.4K]

Answer:

y = 1, 1.319, 1.024, 0

Step-by-step explanation:

Given equation:

y=(1+x)\cos x

\textsf{when}\:x=0:

\begin{aligned} \implies y & =(1+0)\cos 0\\\implies y & = 1\end{aligned}

\textsf{when}\:x=\dfrac{\pi}{6}:

\begin{aligned} \implies y & =\left(1+\frac{\pi}{6}\right)\cos \left(\frac{\pi}{6}\right)\\\implies y & = 1.319\: \sf (3\:dp)\end{aligned}

\textsf{when}\:x=\dfrac{\pi}{3}:

\begin{aligned} \implies y & =\left(1+\frac{\pi}{3}\right)\cos \left(\frac{\pi}{3}\right)\\\implies y & = 1.024\: \sf (3\:dp)\end{aligned}

\textsf{when}\:x=\dfrac{\pi}{2}:

\begin{aligned} \implies y & =\left(1+\frac{\pi}{2}\right)\cos \left(\frac{\pi}{2}\right)\\\implies y & = 0\end{aligned}

Find the anhle measure x in the figure​
Margarita [4]

Answer:

x=25°

Step-by-step explanation:

<u>Sum of angles of a triangle equals 180°</u>

  • x + 10° + 2x + 15° + 3x + 5° = 180°
  • 6x + 30° = 180°
  • 6x = 180° - 30°
  • 6x = 150°
  • x = 150°/6
  • x = 25°

Julia is allowed to watch no more than 5 hours of television a week. So far this week, she has watched 1.5 hours. Write and solv
Leona [35]

The inequality is used to solve how many hours of television Julia can still watch this week is x + 1.5 \leq 5

The remaining hours of TV Julia can watch this week can be expressed is 3.5 hours

<h3><u>Solution:</u></h3>

Given that Julia is allowed to watch no more than 5 hours of television a week

So far this week, she has watched 1.5 hours

To find: number of hours Julia can still watch this week

<em>Let "x" be the number of hours Julia can still watch television this week</em>

"no more than 5" means less than or equal to 5 ( ≤  5 )

Juila has already watched 1.5 hours. So we can add 1.5 hours and number of hours Julia can still watch television this week which is less than or equal to 5 hours

number of hours Julia can still watch television this week + already watched ≤ Total hours Juila can watch

x + 1.5 \leq5

Thus the above inequality is used to solve how many hours of television Julia can still watch this week.

Solving the inequality,

x + 1.5 \leq5\\\\x \leq 5 - 1.5\\\\x \leq 3.5

Thus Julia still can watch Television for 3.5 hours

Which place is the better but
lawyer [7]

Answer:

Stop and Save

Step-by-step explanation:

Find the cost of one apple in each place.

<u>Quick Market</u>:

Divide the total cost with the amount of apples:

1.08/3 = 0.36

The cost for one apple in <em>quick market </em>is $0.36

<u>Stop and Save</u>:

Divide the total cost with the amount of apples:

1.10/5 = 0.22

The cost for one apple in <em>Stop and Save</em> is $0.22

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

$0.22 < $0.36 ∴ <em>Stop and Save</em><em> </em>is cheaper than Quickmarket by $0.14, making Stop and Save your answer.
