Answer: 2^5

Step-by-step explanation:

2^5= 2x2x2x2x2=32

5^2=5×5=25

Answer:

see the picture

Step-by-step explanation:

By the below figure (6) is the initial equation

(1) next added (b/2a)^2 on both sides to make it whole square on left side which gives (4) in (4) both terms are added on the right side to make it (5)

then square root on both sides gives (2) and now taking b/2a to the right side gives the final quadratic formula (3)

We can obtain the quadratic formula from completing the square method as shown.

The quadratic formula is derived from the completing the square method as follows;

Given the quadratic equation;

[tex]ax^{2} + bx + c =0[/tex]

Dividing through by a we have;

[tex]x^{2} + \frac{b}{a} + \frac{c}{a} = 0[/tex]

Adding half of b to both sides of the equation, we have;

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

Taking LCM of the right hand side;

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

Making x the subject of the formula;

[tex]x = \frac{-b + \sqrt{b^2 - 4ac} }{2a}[/tex]

Answer: y=-5/2x+9/2

Step-by-step explanation: We are using (-4,3) as our x and y and -5/2(reciprocal of 2/5) as our slope.

y-3=-5/2(x+4)

multiply x and 4 by -5/2

y-3=-5/2x+3/2

add 3 to both sides

y=-5/2x+9/2

Answer:

⇛-13/8 , -11/24, -7/16, -5/12 , -3/8

Step-by-step explanation:

Given numbers are -3/8 , 5/-12, -7/16, -13/18 , 11/-24

The can be written as -3/8, -5/12, -7/16, -13/18, -11/24

The denominators = 8,12,16,18,24

LCM of the denominators = 144

-3/8 = (-3/8)×(18/18) = -54/144

-5/12 = (-5/12)×(12/12) =-60/144

-7/16 = (-7/16)×(9/9) = -63/144

-13/18 = (-13/18)×(8/8) = -104/144

-11/24 = (-11/24)×(6/6) = -66/144

Ascending order of the numbers

= -104/144 , -66/144, -63/144, -60/144, -54/144

-13/8 , -11/24, -7/16, -5/12 , -3/8

Apply Trignometric ratio

[tex] \cos(x) = \frac{adj \: side}{hypotenuse} \\ \cos(x) = \frac{8}{21} \\ x = \cos { }^{ - 1} ( \frac{8}{21} ) \\ x = 67.6[/tex]

Answer:

  $94,473.31

Step-by-step explanation:

The multiplier in 25 years is ...

  e^(rt) = e^(0.03·25) = e^0.75 ≈ 2.117

To have an account value of $200,000 in 25 years, you need to deposit now ...

  $200,000/2.117 = $94,473.31

_____

When this amount is multiplied by 2.117, the result is 200,000.

[tex]x=\frac{9}{4}[/tex]

Step-by-step explanation:

Answer:

[tex]\boxed{\boxed{\sf x=\frac{9}{4} }\:\sf or \:\boxed{x=2.25}}[/tex]

Step-by-step explanation:

[tex]\sf \cfrac{1}{2}\:x+\cfrac{3}{4}=\:x\cfrac{5}{6}[/tex]

Subtract x (5/6) from both sides:

[tex]\longmapsto\sf \cfrac{1}{2}\: x+\cfrac{3}{4} -x\left(\cfrac{5}{6}\right)=0[/tex]

Subtract 3/4 from both sides:

** Anything subtracted from zero gives its negation.**

[tex]\longmapsto\sf -\cfrac{1}{3}\:x=-\cfrac{3}{4}[/tex]

Multiply both sides by -3, reciprocal of - 1/3

[tex]\longmapsto\sf x=-\cfrac{3}{4} (-3)[/tex]

Express - 3/4 (-3) as single fraction:

[tex]\longmapsto\sf x=\cfrac{-3(-3)}{4}[/tex]

Multiply -3 and -3 = 9

[tex]\longmapsto\sf x= \cfrac{9}{4}[/tex]

Answer:

Step-by-step explanation:

x^2 + y^2 = 9, or x^2 + y^2 = 3^2, is the equation of a circle with center at (0, 0) and radius 2.  It does not represent a line such as y = mx + b.

If you were given both x^2 + y^2 = 9 and y = mx + b, you could find zero, or one, or two points of intersection between circle and line.

x^2 + y^2 = 9 could be solved for either x or y as follows:

x^2 = 9 - y^2, so that x = ±√(9 - y^2).  This is valid for 0 ≤ y < infinity, but again we have not "solve in  y = mx + b" format.

Whats the question?

Step-by-step explanation:

Slope = 3/4

Point = (4,-2)

Using the point Slope form ,

=> x - 4 = 3/4 ( y -(-2))

=> x -4 = 3/4 ( y -2)

=> 4x -16 = 3y -6

=> 4x -3y -16+6=0

=> 4x -3y -10 = 0

Step-by-step explanation:

Step-by-step explanation:

Number 1

m = (y2 - y1)/(x2 - x1)

m = (3 - 1)/(5 - 2)

m = 2/3 POSITIVE

Number 2

m = (y2 - y1)/(x2 - x1)

m = (-3 - 1)/(1 + 2)

m = -4/3 NEGATIVE

Number 3

m = (y2 - y1)/(x2 - x1)

m = (1 - 1)/(5 - 4)

m = 0/1

m = 0 ZERO

Number 4

m = (y2 - y1)/(x2 - x1)

m = (5 - 1)/(7 - 7)

m = 4/0

m = UNDEFINED

Number 5

m = (y2 - y1)/(x2 - x1)
