Answer:

M' (-2 , -5),  A'(1 , -1),  P'(-7 , -1)

Step-by-step explanation:

Rotation clockwise 90° = rotation CCW 270°

Formula for rotation CCW 270° around a point (x',y') for original (x,y)

x'' = (x-x') cos 270° - (y-y') sin 270° + x'

y'' = (x-x') sin 270° + (y-y') cos 270° + y'

cos 270° = 0 and sin 270° = -1

x'' = - (y-y') sin 270° + x' = (y-y') + x'

y'' = (x-x') sin 270°  + y' = (x'-x) + y'

M': x = (4 - -1) + (-7) = -2

     y = (-7 - -3) + (-1) = -5

A': x = (7 - -1) + (-7) = 1

    y = (-7 - -7) + (-1) = -1

check

P': x = (-1 - -1) + (-7) = -7

    y = (-7 - -7) + (-1) = -1

-------------------------------------------------

Another way of thinking is to suppose P is (0,0) and locate other points' coordinate relative to P. Such as M(4,5), A(0,8)..

when it rotate CW 90° (x,y) -> (y , -x) will becomes (5 , -4) and (8 , 0). while (5 , -4) relative to p(-7 , -1) is (-7+5 , -1-4) i.e. ( -2 , -5) at original plane and (1 , -1) for point A'

Answer:

its teaspoons

Step-by-step explanation:

Answer:

a) 22,500  b) 2250 seconds (or 37.5 minutes)

Step-by-step explanation:

a) There are 1000 ml in a liter.

Therefore, the rate of water flowing in can be 3000 ml per minute. To convert this into per second, we divide 3000 by 60.

This becomes 50 ml per second. If the tank fills in completely in 450 seconds,  we multiply 50 by 450 to get how much water in ml was used to fill the tank completely. 50 times 450 = 22,500. Therefore, the capacity of the tank is 22,500.

b) Since water keeps flowing into the tank at a rate of 50 ml per second, and water flows out at a rate of 60 ml per second, we can define the rate flowing out of the tank as 10 ml per second.

Because the maximum capacity of the tank is 22,500 ml, we divide this by 10 ml (the rate flowing out) to get how many seconds it will take for the tank to drain out completely. 22,500 divided by 10 is 2250.

So, it will take 2250 seconds for the tank to drain completely. In minutes, this becomes 37.5 minutes.

The percentage increase in the value of y due to the increase in x by 21% is 10%

Inverse relationship :

y = k/√x - - - - - - (1)

Increase in x by 21% = 0.21

y = k/√1+0.21x

y = k/√1.21x

y = k/ 1.1√x - - - (2)

Comparing the (1) and (2)

y has changed from 1 to 1.1

Increase in y = (1.1 - 1) = 0.1

Expressing the increase as a percentage :

0.1 × 100% = 10%

Hence, the percentage increase in y is 10%

Answer:

5 units

Step-by-step explanation:

Answer:

I think the answer is 7 units

Step-by-step explanation:

you would expect it to be 5 units, but because of the diagonal angle it adds a percentage off each unit

Let x equal the number

 Tip: Go step-by-step

4 times a number is translated to... 4x

Is equal to means =

to the number increased by 21 is... x+21

Your equation is: 4x=x+21

Subtract x from both sides

3x=21

Divide three from both sides

x=7

Check!

Answer:

3x + y = - 9

Step-by-step explanation:

y - 6 = -3 (x + 5)

Distribute the -3

y - 6 = -3x - 15

Add 3x to both sides

3x + y - 6 = -15

Add 6 to both sides

3x + y = - 9

Answer:

  a) Pluto, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, Jupiter

  b) 62

Step-by-step explanation:

When all the numbers are in scientific notation, as these are, the numbers with the smallest exponent are smaller. If numbers have the same exponent, the number with the smaller mantissa is smaller.

a) least-to-greatest diameter, the order is ...

  Pluto, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, Jupiter

__

b) The ratio of diameters of Jupiter and Pluto is ...

  (1.43×10^8)/(2.3×10^6) = 6.2×10^1 = 62

Jupiter's diameter is about 62 times that of Pluto.

Answer:

The negative sign outside the absolute value function causes a few different things when multiplied. When a negative is multiplied outside of the function, the transformation that exists will be a vertical reflection.  A horizontal shift to the left 1 unit will happen because of g(x)=f(x+1). The graph will make a vertical shift down 2 units because of g(x)=f(x)−2. The value of (a) would be -1 and since it is less than 1, and it causes the graph to be wider because of vertical compression. Placing a minus sign outside absolute value bars gives you a negative result.

Answer:

Step-by-step explanation:

There are two ways you can divide 2/3 by 1/6.

1) Division by a number is the same as multiplication by its reciprocal. The reciprocal of a fraction is the fraction obtained by swapping the numerator and denominator. So, division by 1/6 is the same as multiplication by 6/1.

  2/3 ÷ 1/6 = 2/3 × 6/1

The result of this multiplication is the product of the numerators divided by the product of the denominators:

  2/3 × 6/1 = (2×6)/(3×1) = 12/3 = 4

__

2) The fractions can be expressed with the same denominator. Then their quotient is the quotient of their numerators.

  2/3 = 4/6

  2/3 ÷ 1/6 = 4/6 ÷ 1/6 = 4 ÷ 1 = 4

Step-by-step explanation:

The number of yards of material remains sewing blanket is 2.5 yards.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Given that, Keith buys 3 yards of materials to make a blanket.

He trims off a total of 1/6 yards before sewing.

So, 1/6 ×3

= 3/6

= 0.5 yards

Remaining material =3-0.5

= 2.5 yards

Therefore, 2.5 yards of material remain for sewing blanket.

Answer: Middle integer = -24

Step-by-step explanation: First understand the formula for finding three consecutive even numbers.

Formula used: -4(n+n+4)=192

Let's solve your equation step-by-step.

−4(n+n+4)=192

Step 1: Simplify both sides of the equation.

−4(n+n+4)=192

(−4)(n)+(−4)(n)+(−4)(4)=192(Distribute)

−4n+−4n+−16=192

(−4n+−4n)+(−16)=192(Combine Like Terms)

−8n+−16=192

−8n−16=192

Step 2: Add 16 to both sides.

−8n−16+16=192+16

−8n=208

Step 3: Divide both sides by -8.

−8n

−8

=

208

−8

n=−26

Now find the middle integer.

Formula used: n+n+2+n+4

-26+(-26)+2+(-26)+4

-26+(-24)+(-22)

Middle integer=-24
