Reflection across the y-axis

bc it's in the 3rd and it goes into the 4th. this is over the y-axis. in 3rd you coordinates would be (-,-) and in the 4th they would be (+,-) in which case they are in the final triangle

arlik [135]

Answer: For $m\geq15$

$\\\Rightarrow\ y=4+0.75(m-5)\geq4+0.75(15-5)\\\Rightarrow\ y\geq4+0.75(10)\\\Rightarrow\ y\geq4+7.5\\\Rightarrow\ y\geq11.5$

Nick does not has enough money to follow this recommendation.

Step-by-step explanation:

Given: A self-service car wash charges $4 for the initial 5 minutes plus an additional $0.75 for each minute after that.

Let y be the cost for car wash for m minutes then

$y=4+0.75(m-5)$ such that at m= 5 , y=4 which is the cost for car wash (dollars) for first 5 minutes.

Also, A car enthusiast magazine recommends spending at least 15 minutes to properly wash a car.

For $m\geq15$

$\\\Rightarrow\ y=4+0.75(m-5)\geq4+0.75(15-5)\\\Rightarrow\ y\geq4+0.75(10)\\\Rightarrow\ y\geq4+7.5\\\Rightarrow\ y\geq11.5$

But Nick has $10 which is less than $11.5, so he does not has enough money to follow this recommendation.

Use the compound interest formulas A=P1+

Bingel [31]

The accumulated value of an investment if the money is a. compounded semiannually; b. compounded quarterly; c. compounded monthly; d. compounded continuously is $30731.4 $ , $30785.98 $30823.14 , 30841.95

<h3>What is Interest ?</h3>

Interest is the amount received by a person as a result of investing certain amount of money for a certain period of time.

It is given that

Principal = $ 25000

Time = 3 years

Interest Rate = 7 %

The amount is given by

$\rm A = P( 1+ \dfrac{r}{n}) ^{nt}$

Compounded semiannually

n = 2

Compounded Quarterly

n = 4

Compounded Monthly

n =12

Compounded Continuously

P = P₀ $\rm e ^{rt}$

Therefore the accumulated value for

compounded Semiannually is

$\rm A = 25000( 1+ \dfrac{7}{200}) ^{2*3}$

A = $30731.4

Compounded Quarterly

$\rm A = 25000( 1+ \dfrac{7}{400}) ^{4*3}$

A = $30785.98

Compounded Monthly

$\rm A = 25000( 1+ \dfrac{7}{1200}) ^{12*3}$

A = $30823.14

Compounded Continuously

$\rm P = 25000 e ^{ 7 * 3 }$

P = $30841.95

Therefore the accumulated value of an investment if the money is

a. compounded semiannually; b. compounded quarterly; c. compounded monthly; d. compounded continuously is

$30731.4 $ , $30785.98 $30823.14 , 30841.95

NEED HELP ASAP!!! thank you.

Alex17521 [72]

Answer:

See explanation

Step-by-step explanation:

Consider triangles ACM and BCM. In these triangles,

$m\angle 3=m\angle 4$ - given;
$m\angle 1=m\angle 2=90^{\circ}$ - definition of perpendicular lines CM and AB;
$\overline{CM}\cong \overline{CM}$ - reflexive property.

So,

$\triangle ACM\cong \triangle BCM$ by ASA postulate (if one side and two angles adjacent to this side of one triangle are congruent to one side and two angles adjacent to this side of another triangle, then two triangles are congruent).

Two-column proof:

Statement Reason

1. $m\angle 3=m\angle 4$ Given

2. $CM\perp AB$ Given

3. $m\angle 1=m\angle 2=90^{\circ}$ Definition of perpendicular lines CM and AB

4. $\overline{CM}\cong \overline{CM}$ Reflexive property

5. $\triangle ACM\cong \triangle BCM$ ASA postulate

Sloan [31]

Using the equation of the proportional relationship:

Average rate of speed = 60

Time taken to go 300 miles = 5 hrs

Distance travelled in 2.5 hrs = 150 miles

<h3>What is a Equation of a Proportional Relationship?</h3>

A equation of a proportional relationship models the relationship between two variables, x and y, that has a constant of k. It is expressed as y = kx.

Given the following:

Equation: d = 60t

d = distance in miles

t = time in hours

Average rate of speed for the bus = k = 60

Time (t) it would take to go 300 miles (d):

300 = 60(t)

300/60 = t

t = 5 hours

Distance (d) it would travel in 2.5 hours (t):

d = 60(2.5)

d = 150 miles
