Step-by-step explanation:

The two coordinates after the rotation are (2,-3) and (-8,5)

The points are given as:

(-2,3) and (8,-5)

The rule of 180 degrees clockwise rotation is:

(x,y) = (-x,-y)

This means that:

(2,-3) => (-2,3)

(-8,5) => (8,-5)

Hence, the two coordinates after the rotation are (2,-3) and (-8,5)

Answer:

(2, -3) and (-8, 5)

Step-by-step explanation:

If a point is rotated 180° clockwise about the origin (0, 0) then:

(x, y) → (-x, -y)

Therefore,

(-2, 3) → (-(-2),-3) = (2, -3)

(8, -5) → (-8, -(-5)) = (-8, 5)

So the two coordinates after rotation would be (2, -3) and (-8, 5).

Answer:

= y/2

Step-by-step explanation:

(x+3)/3 = (y+2)/2

x/3 + 1 = (y+2)/2

x/3 = (y+2)/2 - 1

= (y+2-2)/2

= y/2

Step-by-step explanation:

[tex]y = 3x \\ \frac{y}{3} = x \\ \\ \frac{3y}{3} + 2y = 45 \\ y + 2y = 45 \\ 3y = 45 \\ y = \frac{45}{3} \\ y = 15 \\ \\ x = \frac{y}{3} \\ = \frac{15}{3} \\ = 5[/tex]

Answer:

Step-by-step explanation:

Because changing from centimeters to meters does not affect the value of the correlation, the correlation will remain 0.964.

The effect does have on the correlation of the two variables should be that it remain the same i.e. 0.964.

Since there is the changing from centimeters to meters so this does not impact the correlation value due to which it remain the constant i.e. 0.964.

Also, the correlation coefficient should be unit -less and the value should always ranged between -1 to 1.

Therefore, it remains the constant.

Answer:

1 year

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

t = 25 / ( 500 × 0.05 ) = 1

t = 1 years

The time required to

accumulate simple interest of $ 25.00

from a principal of $ 500.00

at an interest rate of 5% per year

is 1 year.

Answer:

Step-by-step explanation:

Let the number of cleaners be x

Let the time taken be y

This relationship is inverse

x = k/y

If x = 3 and y = 4

3 = k/4

k = 3*4

k = 12

To get the time it will take 4 people, we will substitute k = 12 and x = 4 into the expression x = k/y

x = 12/4

x = 3

Hence it will take 4 people 3 hours at the same rate

Answer:

B A B B

Step-by-step explanation:

A good trick for fractions is to take the top number and divide it by the bottom number. This gives you the number version of the fraction. For example in question 4. 5/4 is 1.25. And 10/8 is 1.25. therefore they have the same value. Also another good trick. If the top number is more than the bottom number we know it will be 1 something because their is more than the bottom number. So if we have for example question 3 we know that 4 thirds will be at least 1 something if we divide it. And if we look at 8 ninths we know it will be less than 1 something since I is less than nine. Therefore if divided they will have different numbers

Answer: 445

Step-by-step explanation:

Lincoln’s Final Amount:

Compounded Continuously: A=Pe^rt

P= 2800

r= 0.05375

t=15

A=2800e^0.05375(15)

A=2800e^0.80625

A=6270.5833

Lily’s final amount:

Compounded quarterly:

A=P(1+r/n)^nt

P=2800

r=0.05875

t=15

n=4

A=2800(1+ 0.05875/4)^4(15)

A=2800(1.0146875)^60

A=6715.7829

How much more money does Lily have?

6715.7829-6270.5835

=445.1994

The money would Lily have in her account than Lincoln, to the nearest dollar 445.

We have to determine the compound interest Lincoln’s final amount

Compounded Continuously

A=Pe^rt

P= 2800
