VLD [36.1K]

Answer:

3:30PM

Step-by-step explanation:

Martina starting playing video games as soon as she got home from school. She played video games for 15 minutes. Then Martina helped clean the kitchen for 45 minutes. After the kitchen was clean, it took Martina 15 minutes to finish her homework. When Martina finished her homework, it was 4:45 P.M. What time did Martina get home from school?

Step 1

We add up the minutes it took her to do things

= Minutes for video games + Minutes for cleaning the kitchen + Minutes for doing homework

= 15 minutes + 45 minutes + 15 minutes

= 75 minutes

= 1 hour 15 minutes

Step 2

When Martina finished her homework, it was 4:45 P.M. What time did Martina get home from school?

This is calculated be subtracting 1 hour 15 minutes from 4:45 PM

= 4:45 PM - 1 : 15

= 3:30PM

Therefore, Martha got home from school by 3:30 PM

Solve the equation on the interval [0,2π). cos^4x=cos^4xcscx
Alisiya [41]
\bf cos^4(x)=cos^4(x)csc(x)\\\\&#10;-----------------------------\\\\&#10;cos^4(x)=cos^4(x)\cfrac{1}{sin(x)}\implies cos^4(x)=\cfrac{cos^4(x)}{sin(x)}&#10;\\\\\\&#10;cos^4(x)sin(x)=cos^4(x)\implies cos^4(x)sin(x)-cos^4(x)=0&#10;\\\\\\&#10;cos^4(x)[sin(x)-1]=0\to &#10;\begin{cases}&#10;cos^4(x)=0\to x=cos^{-1}(0)\\&#10;----------\\&#10;sin(x)-1=0\\&#10;sin(x)=1\to x=sin^{-1}(1)&#10;\end{cases}

\bf \measuredangle x = cos^{-1}(0)\implies \measuredangle x = &#10;\begin{cases}&#10;\frac{\pi }{2}\\\\&#10;\frac{3\pi }{2}&#10;\end{cases}&#10;\\\\\\&#10;\measuredangle x=sin^{-1}(1)\implies \measuredangle x=\frac{\pi }{2}
