Last trig question!! Please explain how to do this!! Thank youuu !!!!!!
Shalnov [3]

Answer:

See the verification below.

Step-by-step explanation:

Starting expression: sin^3(x)+sin(x)\,cos^2(x)=sin(x)

Extract from the expression on the left of the equal sign the common factor "sin(x)":

sin^3(x)+sin(x)\,cos^2(x)=sin(x)\\sin(x)[sin^2(x)+cos^2(x)]=sin(x)

Now use the Pythagorean trigonometric identity: sin^2(x)+cos^2(x)=1 to replace the expression in between square brackets with "1":

sin(x)[sin^2(x)+cos^2(x)]=sin(x)\\sin(x) \,[1]=sin(x)\\sin(x)=sin(x)

Therefore we have verified the identity

Solve the equation for x. 25x = 275 <br><br>x =​
Sliva [168]

Answer:

x = 11

Step-by-step explanation:

So the equation is  25x = 275. In order for us to find out what x is we need to get rid of 25 that is next to x, so we are going to have to divide 25x by 25. What you do to one side you do to the other so the equation will look like this:

25x/ 25 = 275/ 25

25x/25 = x

275/25 = 11

so x = 11

AlekseyPX

Answer:

20 ounces

Step-by-step explanation:

The line plot is attached below.

From the line plot, we can see that there is a total of 7 snack mix. Two of the snack mix weigh 1 and half (1.5) ounces each, one snack measure 2 and three quarter (2.75) ounce, three snack mix measure three and half (3.5) ounce each and one snack measure 3 and three quarter (3.75) ounce. Therefore the total weight of the snack mix is:

Total weight = (2 * 1.5) + (1 * 2.75) + (3 * 3.5) + (1 * 3.75)

Total weight = 20 ounces
