find the perimeter of J(-4,2), K(1,2), L(2,-2) and M(-3,-2)

Answers

Answer 1

Answer:

Perimeter = 31.12

Step-by-step explanation:

The perimeter of the shape JKLM will be expressed as;

Perimeter = JK + JL + JM + KL + KM + LM

Using the formula for calculating the distance between two points;

D = √(x2-x1)²+(y2-y1)²

For JK where  J(-4,2) and K(1,2)

JK = √(1+4)²+(2-2)²

JK = √5²

JK =√25

JK = 5

For JK where  J(-4,2) and L(2,-2)

JL = √(2+4)²+(-2-2)²

JL = √6²+(-4)²

JL =√36+16

JL = √52

For JM where  J(-4,2) and M(-3,-2)

JM = √(-3+4)²+(-2-2)²

JM = √1²+(-4)²

JM =√1+16

JM = √17

For KL where  K(1,2), L(2,-2)

KL = √(2-1)²+(-2-2)²

KL = √1²+(-4)²

KL =√1+16

KL = √17

For KL where  K(1,2), M(-3,-2)

KM = √(-3-1)²+(-2-2)²

KM = √4²+(-4)²

KM = √16+16

KM = √32

KM = 4√2

For KL where  L(2,-2) and M(-3,-2)

LM = √(-3-2)²+(-2+2)²

LM = √(-5)²+(0)²

LM = √25

LM = 5

Perimeter = 5 + 4√2 + √17  + √17 + 5 + √52

Perimeter = 10 + 4√2 + 2√17 + √52

Perimeter = 10+5.66+8.25+7.21

Perimeter = 31.12

Find the balance of the account.

This is simple interest btw. I also need a explanation too​

Answers

Answer:

$1680

Step-by-step explanation:

I = 5%

P = $1600

period = 1 year

$1600 + 15% = $1680

Answer:

$1680.

Step-by-step explanation:

The interest for 1 year = 1600 * 5%

= 1600 * 0.05

= $80.

So the new balance = old balance + interest

= 1600 + 80

= $1680.

What is HL? Trapezoid

Answers

Answer:

HL = 21

Step-by-step explanation:

HL is the midsegment of the trapezoid shown above. Thus, it follows that:

HL = (JK + GF)/2

JK = 12

GF = 2.5(JK) = 2.5(12) = 30

Plug in the values:

HL = (12 + 30)/2

HL = 42/2

HL = 21

To avoid confusion in using the word "particle," one must state that a particle is an identifiable part of dust, a molecule, an atom, or an electron.  This means that particles form these elements.

Step-by-step explanation:

write a quadratic function in standard form whose graph passes through (-5 0) (0,-8) and (4,0).

Answers

The required quadratic function in the standard form is f(x) = -1.25 x² + 5x.

What is a quadratic equation ?

A quadratic equation is an equation which contains a single variable of degree 2 and its general form is ax² + bx + c = 0.

The x - intercepts of the quadratic equation are (-5, 0) and (0 , -8). That meant (x + 5) and (x -0) are two factors of quadratic equation.

f(x) = a (x + 5) (x - 0)

f(x) = ax² + 5x

The graph of quadratic equation passes through (4 , 0). So we need to substitute x = 4 , f(x) = 0 in equation 1.

0 = a × 4² + (5 × 4)

0 = a × 16 +20

a = -20/16

We know that quadratic equation is in form ax² + bx + c = 0.

f(x) = [tex]\frac{-20}{16}[/tex] × x² + 5x

f(x) = [tex]\frac{-5}{4}[/tex]x² + 5x

f(x) = -1.25 x² + 5x  

Therefore , the required quadratic function in the standard form is f(x) = -1.25 x² + 5x.

7) What is the equation of a circle with the center (-8, 9) and the radius of 10?​

Answers

Answer:

(x+8)² + (y - 9)² = 100

Step-by-step explanation:

The general equation of a circle is expressed as;

(x-a)² + (y - b)² = r² where;

(a, b) is the centre of the circle

r is the radius

Given

Centre (-8, 9) where a = -8, b = 9

radius r = 10

Substitute into the formula to get the required equation;

(x-(-8))² + (y - 9)² = 10²

(x+8))² + (y - 9)² = 10²

(x+8)² + (y - 9)² = 100

Hence the required equation is (x+8)² + (y - 9)² = 100

No. of remaining days = [tex]\frac{7}{8}[/tex] - [tex]\frac{1}{8}[/tex]

If the denominators are the same, you can directly do the working for the numerators while leaving the denominator alone.

[tex]\frac{7}{8}[/tex] - [tex]\frac{1}{8}[/tex] = [tex]\frac{6}{8}[/tex]

6 and 8 both have a common factor of 2, so we can further simplify this fraction.

Step-by-step explanation:

just did it on plato

The numerical expression [tex]\rm (x - 2)^{1/4} = 1[/tex], √x² + 7 = 4, and ∛(1 - x) = -1 are correctly matched with 18, -3, and 2.

What is simplification?

Simplification is to make something easier to do or understand and to make something less complicated.

The expressions are given below.

[tex]\rm (x - 2)^{1/4} = 1[/tex], √x² + 7 = 4, and ∛(1 - x) = -1

Then By simplification, we have

x - 2 = 2⁴

    x = 16 + 2

    x = 18

√x² + 7 = 4

x + 7 = 4

x = -3

∛(1 - x) = -1

    1 - x = -1³

        x = 2

The numerical expression [tex]\rm (x - 2)^{1/4} = 1[/tex], √x² + 7 = 4, and ∛(1 - x) = -1 are correctly matched with 18, -3, and 2.
