Hey there! I'm happy to help!

Standard form is just writing this without the multiplication sign. If you multiply a number by 10 to a negative number, \you take the number in the negative exponent and move the decimal to the left that many times. In our case, we move it to the left 8 times.

If we move the decimal to the left 8 times, we have 0.00000007.

I hope that this helps! :D

Question 6 (Essay Worth 2 points)<br> Find all polar coordinates of point P = (2, 14°).

andrey2020 [161]

Answer:

(2,14°+360n) and (-2,14°+(2n+1)180°)

Step-by-step explanation:

You start out with (2, 14°)

The polar coordinate can be written as (r, 0) = (r, 0+2nπ) or

(r,0)=(-r,0+2(n=1)π), where n is any integer.

The polar coordinates point : p=(r,0) = (2,14°)

For the positive value of r, the polar coordinate can be written as

p=(2,14°) = (2,14°+360n°), where n is any integer.

For the negative value of r , the polar coordinate can be written as

p=(2,14°) = (-2,14°+(2n+1)180°), where n is any integer.

All the polar coordinates of point P are(2,14°+360n) and (-2,14°+(2n+1)180°).

In circle M shown, diameter SW intersects chord VT at R such that m arc VS = 146 degrees and m arc ST = 64 degrees. Which of the

Mandarinka [93]

Answer:

(3) 49

Step-by-step explanation:

The circle diagram is attached below. angle mVS = 146°

and angle mST = 64°.

mWT = 360 -64 - 146 = 150 (angle at a point)

∠ VWS = 73° = mVS / 2

MVW = 180 - 146 = 34 (angle in a straight line)

MVW = 180 -73 - 34 = 73° (angle in a triangle)

∠TMR = 180 - 64 = 116° (angle on a straight line)

∠VMT = 116 + 34 = 150°

∠ MVT = ∠ MTV (base angles of an isosceles triangle)

150 +2∠ mTV = 180

∠ MTV = 15°

∠RVW = 73 - 15 = 58°

∠RVW + ∠ VWS + ∠VRW = 180

∠VRW = 180 - 58 - 73 = 49

How to solve this for x

timama [110]

the answer is x= 10.

the steps would go like this.

4 + 3/5 × (15 + 2x) = 25

4 + 9 + 6/5x = 25

13 + 6/5x = 25

65 + 6x = 125

6x = 125 -65

6x = 60

x = 10

hope this helps
