Step-by-step explanation:

B becuase it keeps the same orientation and have the same distance from each point and they both produce rigid motion.

A is a reflection.

C is a dilation.

D is a rotation.

Larissa invested $19,000 in an eleven-year CD giving 7.5% interest, but needed to withdraw $2,500 after four years. If the CD’s penalty for earlywithdrawal was one year’s worth of interest on the amount withdrawn, how much money did Larissa have when the CD reached maturity, not including the amount she withdrew

Find the area of the region between two concentric circular paths. If the radii of the circular paths are 210 m. and 490 m. resp

taurus [48]

Given :

The radii of the circular paths are 210 m. and 490 m.

To Find :

The area of the region between two concentric circular paths.

Solution :

Area of the outer circle :

$\: \qquad \dashrightarrow \sf{{ \pi \: \times {(490)}^{2} {m}^{2}}}$

$\: \qquad \dashrightarrow \sf{{ \ \dfrac{22}{7} \times \:490 \times 490 \: {m}^{2}}}$

$\: \qquad \dashrightarrow \sf{{ \ \dfrac{22}{ \cancel{7}} \times \cancel{490} \times 490 \: {m}^{2}}}$

$\: \qquad \dashrightarrow \sf{{ \ {22} \times 70 \times 490 \: {m}^{2}}}$

$\: \qquad \dashrightarrow \bf{{ \ 754600 \: {m}^{2}}}$

⠀

Area of the inner circle :

$\: \qquad \dashrightarrow \sf{{ \pi \: \times {(210)}^{2} {m}^{2}}}$

$\: \qquad \dashrightarrow \sf{{ \ \dfrac{22}{7} \times \:210 \times 210 \: {m}^{2}}}$

$\: \qquad \dashrightarrow \sf{{ \ \dfrac{22}{ \cancel{7}} \times \cancel{210} \times 210 \: {m}^{2}}}$

$\: \qquad \dashrightarrow \sf{{ \ {22} \times 30 \times 210 \: {m}^{2}}}$

$\: \qquad \dashrightarrow \bf{{ \ 138600 \: {m}^{2}}}$

⠀

Therefore,

Area of the region inside the circular paths :

$\: \qquad \dashrightarrow \sf{{ \ (754600 - 138600 ) \: {m}^{2}}}$

$\: \qquad \dashrightarrow \bf{{ \ 616000 \: {m}^{2}}}$

Compare the quantities in Column A and Column B.

GaryK [48]

The y-intercept of $2y = 3x - 4$ and the y-intercept of $4x - 2y=4$ are equal

The equations are given as:

$2y = 3x - 4$

$4x - 2y=4$

Make y the subject in both equations

<u>First equation</u>

$2y = 3x - 4$

$y = \frac 32x - 2$

<u>Second equation</u>

$4x - 2y=4$

$y = 2x - 2$

A linear equation is represented as:

$y = mx + b$

Where b represents the y-intercept

So: By comparison,

$b_1 = 2$ --- the y-intercept of the first equation

$b_2 = 2$ --- the y-intercept of the second equation

2 = 2.

Hence, the y-intercept of $2y = 3x - 4$ and the y-intercept of $4x - 2y=4$ are equal

3(x+14)=42 plz need help now

lina2011 [118]

Answer:

0

Step-by-step explanation:

So we have the equation:

$3(x+14)=42$

Divide both sides by 3:

$x+14=14$

Subtract 14:

$x=0$

The value of x is 0
