Help me Brainly ASAP

Answer and Step-by-step explanation:

Simply solve for x (very easy to do).

4x + 9 = 41

Subtract 9 from both sides of the equation.

4x = 32

Divide both sides of the equation by 4.

x = 8

x is equal to 8.

1. The given series is

 4 ⋅ 6 + 5 ⋅ 7 + 6 ⋅ 8 + ... + 4n( 4n + 2) =  

For n=1

L.H.S=4.6=24

R.H.S=[4×5×15]÷6

      =300÷6

      =50

So, for n=1,

L.H.S≠ R.H.S

Since the given expression is true for n=1 ,

So , the given series is untrue.

we should replace R.H.S by=4(n+1)(n+2)(4n-3)²

2.

12+42+72+.......+(3 n -2)2=

For n=1,

L.H.S=12

R.H.S=1×(6-3-1)/2

       =2/2

      =1

As L.H.S≠ R.H.S

We should Replace R.H.S by [(3 n-1)(3 n-2)]2

3.The given sequence is

2+4+6+....+2n=n(n+1)

L.H.S

P(1)=2

R.H.S

1×(1+1)

=1×2

=2

( b)  L.H.S

P(n)=2+4+6+.....2 k

This is an A.P having n terms.

tex]S_{n}=

              = n(n+ 1)

R.H.S=n(n+1)

So, P(k)=k(k+1)

(c) P(k+1)=2+4+6+.......+2(k+1)

This is an A.P having (k+1) terms.

              =(k+1)(k+2)

So, P(k+1)= (k+1)(k+2)

Answer:

(2x + 35)/3

Step-by-step explanation:

f(2x + 3) = 3x - 8

= 3(2x)/2 - 8

= 3(2x + 3 - 3)/2 - 8

= 3(2x + 3)/2 - 3(3)/2 - 8

= ( 3(2x + 3) - 25)/2

Therefore, f(x) = (3x - 25)/2

Let f(x) = (3x - 25)/2 = y

Therefore,

x = (2y + 35)/3 = f(y)

Hence,

f-¹(x) = f(y) = (2y + 35)/3

Just by merely replacing y,

f-¹(x) = (2x + 35)/3

Answer:

Step-by-step explanation:

[tex]let~g(x)=2x+3,~ then~f\circ g(x)=f(g(x)=3x-8\\\\[/tex]

lets assume that f(x) is a line, so f(x)=mx+b

[tex]f(g(x))=m(2x+3)+b=2mx+3m+b=3x-8[/tex]

the follow equation system results:

[tex]2m=3 \\ 3m+b=-8[/tex]

[tex]m=\frac{3}{2}\\\\b=-\frac{25}{2}[/tex]

finally:

[tex]y=f(x)=\frac{3}{2}x-\frac{25}{2}[/tex]

now is time to calculate the inverse function:

[tex]y=\frac{3}{2}x-\frac{25}{2}=>2y+25=3x=>x=\frac{2}{3}y+\frac{25}{3}[/tex]

so

[tex]f^{-1}(x)=\frac{2}{3}x+\frac{25}{3}[/tex]

==========================================================

Explanation:

For now, focus on the triangle with angles 'a', 71 and 40 degrees.

Recall that for any triangle, the inside angles always add to 180

a+71+40 = 180

a+111 = 180

a = 180-111

a = 69

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

Notice how angles b and 133 are adjacent and form a straight angle. This makes them supplementary. Meaning they add to 180

b+133 = 180

b = 180-133

b = 47

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

Let angle f be adjacent to angle c, and part of the triangle with angles 'a' and b.

Use the rule mentioned in the first section

a+b+f = 180

69+47+f = 180

116+f = 180

f = 180-116

f = 64

Now we can find angle c, because angles f and c are supplementary

c+f = 180

c+64 = 180

c = 180-64

c = 116

We could also use the remote interior angle theorem to say that a+b = c, so c = a+b = 69+47 = 116

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

Next, focus your attention on the 140 degree angle. The missing adjacent angle to this is 180-140 = 40 degrees

Now focus on the triangle that has angles d, 40, and 47. The "40" being what we just calculated in the previous paragraph.

We'll do the same thing as before

d+40+47 = 180

d+87 = 180

d = 180-87

d = 93

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

The angle just above angle d is also the same (vertical angles). This upper triangle has angles 40, d and g, where g is unknown. Let's find it.

40+d+g = 180

40+93+g = 180

133+g = 180

g = 180-133

g = 47

The vertical angle across from this is also 47 degrees.

Similarly, we can move that angle b over to its vertical pairing counterpart.

The smallest triangle at the very top has angles e, b, and g

e+b+g = 180

e+47+47 = 180

e+94 = 180

e = 180-94

e = 86

Answer:

[tex]P=16ft[/tex]

Step-by-step explanation:

From the question we are told that:

Diameter [tex]d=16ft[/tex]

Depth [tex]dp=1ft[/tex]

Generally the equation for a Parabola is mathematically given by

 [tex]y=ax^2[/tex]

Since of the parabola has

Diameter [tex]d=16ft[/tex]

Depth [tex]dp=1ft[/tex]

Therefore it passes through

 [tex]x=(8,1)[/tex]

Therefore

 [tex]1=a(8)^2[/tex]

 [tex]a=\frac{1}{64}[/tex]

Since P(distance from focus to the vertex)

 [tex]a=\frac{1}{4p}[/tex]

Substituting

 [tex]\frac{1}{64}=\frac{1}{4p}[/tex]

 [tex]P=16ft[/tex]

Answer:

  5x +2y = 20

Step-by-step explanation:

Suppose 'a' is the x-intercept of the line.

Then the slope is given by the slope formula ...

  m = (y2 -y1)/(x2 -x1)

  m = (0 -5)/(a -2)

And the y-intercept is ...

  b = y -mx = 5 -(-5/(a-2))(2) = 5 +10/(a -2)

The area of the triangle is half the product of 'a' and 'b', so is ...

  A = 1/2ab

  A = 1/2(a)(5 +10/(a -2)) = 2.5a +5a/(a-2)

The area is minimized when the derivative of this is zero.

  A' = 2.5 -10/(a -2)^2 = 0

Solving for 'a' gives ...

  (a -2)^2 = 10/2.5 = 4

  a = 2 + 2 = 4 . . . . . . . . . . . x-intercept

  b = 5 +10/(4 -2) = 10 . . . . . y-intercept

  m = -5/(4 -2) = -5/2 . . . . . . slope

An equation of the line is ...

  y = -5/2x +10 . . . . . slope-intercept form

  5x +2y = 20 . . . . . standard form

You may have noticed that the x-and y-intercepts are double the x- and y-values of the given point. That is, the given point is the midpoint of the hypotenuse of the triangle with minimum area. That is the general solution of this sort of problem.

Answer:

1/12

Step-by-step explanation:

The first time the person picks a magazine, they have a 5/10 chance of drawing an architecture magazine.

The second time, they have a 4/9 chance because they have already removed one magazine from the bookshelf

The third time, they have a 3/8 chance because they have already removed 2 magazines.

Multiply all of the probabilities together

5/10 * 4/9 * 3/8 = 60/720

Simplify:

60/60 / 720/60 = 1 / 12

Hope this helps!

Answer:

m<D = 120°

Step-by-step explanation:

Adjacent angles are supplementary in a parallelogram.

Thus:

2x + 12 + 5x = 180°

Collect like terms

7x + 12 = 180

7x = 180 - 12

7x = 168

x = 168/7

x = 24

✔️m<D = 5x° (opposite angles in a parallelogram are equal)

Plug in the value of x

m<D = 5(24)

m<D = 120°

Answer:

y = 3/5x - 1

Step-by-step explanation:

y = mx + b

m = slope

m = 3/5

to find the y - intercept we have to make x = 0 by adding or subtracting

in this case it is +5

add five to both x and y

[tex](-5, -6) + (5, 5) = (0, -1)[/tex]

the y intercept focuses on what y is when x is 0

the y intercept in this case is -1
