Answer:

The length of side PQ is 2 units.

The length of side QR is 2.24 units.

The perimeter of the parallelogram PQRS is about 8.48 units.

Step-by-step explanation:

The given figure is as follows :

To find - The length of side PQ is ....... units.

              The length of side QR is about ......... units.

               The perimeter of the parallelogram PQRS is ........

Solution -

From the figure , we can see that

P = (-5, 3)

Q = (-3, 3)

R = (-4, 1)

S = (-6, 1)

Now,

By distance formula, we get

PQ = √(3 - 3)² + (-3 + 5)²

     = √0 + 2²

     = √4

     = 2

∴ we get

The length of side PQ is 2 units.

Now,

QR = √(1 - 3)² + (-4 + 3)²

     = √(-2)² + (-1)²

     = √4 + 1

     = √5

     = 2.236

∴ we get

The length of side QR is 2.24 units.

Now,

We know that,

Perimeter of Parallelogram = 2(a + b) where a is the base and b is the side

Here Given that,

a = 2

b = 2.24

So,

Perimeter of parallelogram PQRS = 2(2 + 2.24)

                                                         = 2(4.24)

                                                         = 8.48

∴ we get

The perimeter of the parallelogram PQRS is about 8.48 units.

Answer:

PQ 2 units

QR 2.24 units.

Answer:

The components of the vector are [tex]x = 2[/tex] and [tex]y = 6[/tex], respectively.

Step-by-step explanation:

The components of the vector is equal to the vector position of the terminal point relative to the initial point ([tex]\vec v[/tex]), that is:

[tex]\vec v = B(x,y) - A(x,y)[/tex] (1)

Where:

[tex]A(x,y)[/tex] - Initial point.

[tex]B(x,y)[/tex] - Terminal point.

If we know that [tex]A(x,y) = (-5,-5)[/tex] and [tex]B(x,y) = (-3,1)[/tex], then the vector is:

[tex]\vec v = (-3,1) -(-5-5)[/tex]

[tex]\vec v = (2, 6)[/tex]

The components of the vector are [tex]x = 2[/tex] and [tex]y = 6[/tex], respectively.

that’s what’s right on khan

Answer:

Step-by-step explanation:

If we subtract 7 from both sides, we get -2 on the right.  This is not possible, since absolute values are always 0 or greater.

Answer:

− 1.5 f  −19

that's the correct answer.

Answer:

Option D.

Step-by-step explanation:

We have the inequality:

3 + (5/2)*x ≥ 2*x - 13/2

First, let's  try to isolate x in one side of the inequality:

3 + (5/2)*x ≥ 2*x - 13/2

(5/2)*x ≥ 2*x - 13/2 - 3

(5/2)*x - 2*x ≥  - 13/2 - 3

Now all the terms with an x are in the left, and the terms without are in the right.

We can rewrite this inequality as:

(5/2)*x - (4/2)*x ≥  - 13/2 - 6/2

(1/2)*x ≥ -19/2

Now, multiplying both sides by 2 we get:

2*(1/2)*x ≥ (-19/2)*2

x ≥ - 19

So the graph will be a solid point in x = -19, and a ray that extends to the right (the values that are larger than -19)

The correct option is the last graph, option D.

Answer:

It will fit

Step-by-step explanation:

165 / 15 = 11

So b = 11

12.5 can fit in 15

and 5.3 can fit in 11 so it will fit.

4 Packs of water and 7 Packs of candy bars.

So, we wanna know the smallest number that both 35 and 20 will go into.

Find the Least Common Multiple (LCM), but to find the LCM we need to find the prime factorization of each of the following number :-

[tex] \sf {35 = 5(7)}[/tex]

[tex] \sf \red {20 = 5(4)}[/tex]

[tex] \sf {4 = 2(2)}[/tex]

[tex] \sf \red {20 = 5(2)(2)[/tex]

~Now multiply all the numbers by 5 :-

[tex] \sf \pink{5(7)(2)(2) = 35(2)(2) = 70(2) = 140}[/tex]

This means she needs 140 bottles of water and 140 candybars.

Water is sold in packs of 35, this means that she needs :

[tex] \sf \orange{ \frac{140}{35} = 4\: packs \: of \: water}[/tex]

Candy bars are sold in packs of 20, this means she needs :

[tex] \sf \green{ \frac{140}{20} = 7 \: packs \: of \: candy \: bars}[/tex]

Answer:

Option a: m ≠ 0

Step-by-step explanation:

After a small online search, I've found that the complete question is:

If the function f(x) = m*x + b has an inverse function, which statement must be true?

a) m ≠ 0

b) m = 0

c) b ≠ 0

d) b = 0

Ok, if g(x) is an inverse of the function f(x), then:

g( f(x)) = x

f( g(x)) = x

Let's assume that f(x) = m*x + b  has an inverse, and this inverse function is g(x).

Because f(x) is linear, g(x) is also linear, then:

g(x) = n*x + c

Let's find the values of A and B.

We know that:

f( g(x)) = x =  m*(n*x + c) + b

then

x = m*n*x + m*c + b

Then we must have:

m*n = 1

(m*c + b)  = 0

From the first equation m*n = 1

We get:

n = 1/m

The slope of the inverse function is one over the slope of the original function.

Because m is on the denominator, m can not be equal to zero (because a division by zero is not defined)

Then the correct option is the option a, m ≠ 0.

Answer:

angle 1 is 90

angles 2 and 3 are 65

angle 4 is 25

Answer:

Step-by-step explanation:

Given function in the question is,

[tex]f(x)=\frac{-2x^2-4x}{4x+8}[/tex]

       [tex]=\frac{-2x(x+2)}{4(x+2)}[/tex]

       [tex]=-\frac{1}{2}x[/tex] If [tex]x\neq -2[/tex]

Given function is not defined at x = -2

At x = -2,

[tex]f(-2)=\frac{1}{2}(2)[/tex]

          [tex]=1[/tex]

Therefore, there is a hole in the graph at (-2, 1).

Graph of the function 'f' will be a straight line with a hole at (-2, 1).

Horizontal asymptote → None

Vertical asymptote → None

x-intercept → No x-intercept [Line passes through origin (0,0)]

y-intercept → No y-intercept [Line passes through origin (0,0)]

Hole → (-2, 1)
