Answer:

[tex]1-\cos \left(x\right)[/tex]

Step-by-step explanation:

[tex]\frac{\sec \left(x\right)\sin ^2\left(x\right)}{1+\sec \left(x\right)}[/tex]

Use the identity: [tex]\sec \left(x\right)=\frac{1}{\cos \left(x\right)}[/tex]

[tex]\frac{\frac{1}{\cos \left(x\right)}\sin ^2\left(x\right)}{1+\frac{1}{\cos \left(x\right)}}[/tex]

[tex]\frac{\frac{1}{\cos \left(x\right)}\sin ^2\left(x\right)}{\frac{\cos \left(x\right)+1}{\cos \left(x\right)}}[/tex]

[tex]\frac{\frac{\sin ^2\left(x\right)}{\cos \left(x\right)}}{\frac{\cos \left(x\right)+1}{\cos \left(x\right)}}[/tex]

Divide them using [tex]\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\times d}{b\times c}[/tex]

[tex]\frac{\sin ^2\left(x\right)\cos \left(x\right)}{\cos \left(x\right)\left(\cos \left(x\right)+1\right)}[/tex]

Cancel cos(x):

[tex]\frac{\sin ^2\left(x\right)}{\cos \left(x\right)+1}[/tex]

Use the identity: [tex]\sin ^2\left(x\right)=1-\cos ^2\left(x\right)[/tex]

[tex]\frac{1-\cos ^2\left(x\right)}{1+\cos \left(x\right)}[/tex]

[tex]\frac{-\left(\cos ^2\left(x\right)-1\right)}{1+cos(x)}[/tex]

Use the difference of squares formula:

[tex]-\frac{\left(\cos \left(x\right)+1\right)\left(\cos \left(x\right)-1\right)}{1+\cos \left(x\right)}[/tex]

Cancel out 1+cos(x):

[tex]-\left(\cos \left(x\right)-1\right)[/tex]

Remove outer bracket:

[tex]-\cos \left(x\right)+1[/tex]

[tex]1-cos(x)[/tex]

Step-by-step explanation:

Answer:

The Observation made about the distances between three pairs of corresponding vertices is that the distance between each translated pair must be equal to the distance between every translated pair . i.e distance between A and A' = distance between B and B' = distance between C and C'  

Step-by-step explanation:

The Observation made about the distances between three pairs of corresponding vertices is that the distance between each translated pair must be equal to the distance between every translated pair . i.e distance between A and A' = distance between B and B' = distance between C and C'  

from this observation Translation is the movement of all vertices of  shapes at a fixed distance along a given co-ordinate, The movement of the vertices of a shape at a fixed distance is just another way of defining the movement of the points of a shape at a fixed distance in relation  to translation

Answer:

Each distance between the three pairs of corresponding vertices is the same. Based on this observation, a translation is a transformation in a coordinate plane that moves the vertices of a shape a fixed distance. In fact, a translation moves all points on a shape a fixed distance.

"To understand the calculation, check below."

Midpoint

The middle point of the a line segment is called the midpoint.

It's really the centroid of both segment and the ends, and it is equidistant from both.

It cuts the portion in half.

[tex]B[/tex] is the midpoint of [tex]

AC[/tex] [tex]\boldsymbol{AB=BC}[/tex][tex]3x-1=x+7[/tex] [tex]2x

AC=8[/tex] [tex]\boldsymbol{x=4}[/tex]

So,[tex]BC=4+7[/tex] [tex]=\boldsymbol{11}[/tex]

Therefore,[tex]AC=2BC[/tex] [tex]=2 \times 11\\=\boldsymbol{22}[/tex]Length of [tex]\boldsymbol{AC}[/tex] is [tex]\boldsymbol{22}[/tex] units.

Answer:

the new end point is (-10,11).

Answer:

x²+1 is the second

Step-by-step explanation:

2x+24=40°

4x+43=75°

x²+1=65°

(2x+24) + (4x +43) + (x²+1)=180

x²+6x+68=180

x1=-14

x2=8

since there's no negative angle, we'll use x=8

Answer:

Step-by-step explanation:

√a^2 + b^2 =a+b

√ (a+b)^2 =a +b

The square root and the square cancel making

√a^2+b^2=a+b

Just subtract the sum of 1/4 and 1/3 on 1

.

1 - [(1/3) + (1/4)]

Get the least common denominator. LCD = 12

= 12/12 - [(4/12) + (3/12)]

= 12/12 - (7/12)

= 5/12

.

Therefore, 5/12 of the tank is empty.

Answer:

The absolute value of -10 is -10

Step-by-step explanation:

Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative.

...

Absolute Value  (For example)

|6| = 6 means the absolute value of 6 is 6.

Answer:

The absolute value of -10 is just 10.

Step-by-step explanation:

Anything that comes out of the absolute value brackets, which look like this |-10|, becomes positive.

For example the absolute value of  -|-10| is -10. Why? Well, because the absolute value of the -10 inside is 10, but then you have to add the negative that is outside that bracket so the answer is -10.

If the number inside the bracket is positive, is comes out the way it is, positive.

Answer: 20 mL

Step-by-step explanation:

According to Archimedes, the upward force exerted on a body immersed in a fluid is equal to the weight of the fluid the body displaces.

i.e. weight of the object = weight of the fluid displayed

Given: George put 25 mL of water into a graduated cylinder. After adding a solid object, the water level in the cylinder rose to 45 mL.

So, the volume of the object = New volume - Original volume

= 45 mL - 25 mL

= 20 mL

Hence, the volume of the object =20 mL

Answer:

1. x/4

2. 2/3+x

3. 9-n

Step-by-step explanation:

1. "A number" is an unknown value, so we set that as the variable. When a number is being divided, it's the divisor in a division problem (the first number)

2. The "sum" is the answer to an addition problem (like how the "quotient" is the answer to a division problem), which is why we know to add. Again, "a number" is the unknown value so we set that as the variable.

3. Because Drew is "n" years younger than Joe, Joe's age - n = Drew's age. The question tells us that Joe is 9 years old, so the expression would be 9-n.

I hope this helps! If it does, a brainliest would be much appreciated :)

Answer:

The answer would be C

Step-by-step explanation:

This is because you would use the distributive property, so you would distribute the 21 to the 13 and the 5. Then you would multiply those two, and then add them, and add the separate 9 to them. Hope this helps :)
