(x-h)^2 + (y-k)^2 = r^2
(h, k) = (-5, -1)
r = 5
(x+5)^2 + (y+1)^2 = 5^2
(x+5)^2 + (y+1)^2 = 25

On the rectangular coordinate system, what is the shortest distance between points (−4, 3) and (−2, −1)?

pogonyaev

Shortest Distance = $\sqrt{ (-4+2)^{2} + (3+1)^{2} }$
Shortest Distance = $\sqrt{ (-2)^{2} + (4)^{2} }$
Shortest Distance = $\sqrt{20}$
Shortest Distance = $4.47 units$

Use the following expression to

IgorLugansk [536]

Answer:

part A :BODMAS ( Bracket of Division Multiplication Addition Subtraction )

part b; Bracket (2+3.2) = - 2- 3.2

= 16- 2-3.2 +30-5

ADDITION:-3.2+30 = - 33.2

16-2(-33.2)30-5

14-33.2 +30-5

14-33.2 +25

-19.2+25

-44.2

Step-by-step explanation:

THE FOLLOWING EQUATION CAN ONLY BE SOLVED USING BODMAS

Please help! Select all that apply. Write the letter of your answer. V = Iwh

Delicious77 [7]

Answer:

Step-by-step explanation:

Formula for volume of a cuboid $= lwh$ . where l is the length, w is the width and h is the height.

Using this equation we can answer the question by using the values given.

$V = (2y+4)(2y-4)(3y) = (4y^2-16)(3y) = 12y^3-48y$

From the list of answers, we can compare each one to the answer we got and see if they match up.

The answers that match up are:

C. $12y^3-48y$ - it is exactly like the answer we got.

D. $3y(4y^2-16) = 12y^3-48y$ - if we simplify the brackets, it is exactly like the answer we got.

E. $(2y+4)(6y^2-12y)=12y^3-24y^2+24y^2-48y=12y^3-48y$ - once again, if we simplify the brackets it is like the answer we got.

None of the other answers are correct as they do not match up with the answer we got.

Suppose that y varies directly with x, and y=3 when x=8

spayn [35]

we are given

y varies directly with x

so, we can write equation as

$y=kx$

where

k is a constant

now, we need to find k

we are given

y=3 when x=8

so, we can plug it and find k

$3=k*8$

$k=\frac{3}{8}$

now, we can plug it back

$y=\frac{3}{8}x$

(A)

we have got equation as

$y=\frac{3}{8}x$

for finding inverse , we can switch x and y

$x=\frac{3}{8}y$

now, we can solve for y

$8*x=8*\frac{3}{8}y$

$8*x=3y$

$f^{-1}(x)=\frac{8x}{3}$ ............Answer

(B)

we have

$y=\frac{3}{8}x$

we can plug x=4 and find y

$y=\frac{3}{8}*4$

$y=\frac{3}{2}$ ................Answer
