10+-23=-13

Answer:

the answer is -13

Step-by-step explanation:

The inverse of the function is f(x) = 8x – 3 and g ( x ) = x + 3/8. The correct option is B.

A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.

The inverse function of a function f in mathematics is a function that reverses the operation of f. If and only if f is bijective, then the inverse of f exists, and if it exists.

The inverse of the function is given by,

f(x) = 8x – 3 and g ( x ) = x + 3/8

The inverse of the function is calculated by dividing the function by the coefficient of x and reversing the sign of the function.

f(x) = 8x – 3

Divide the function by 8.

f(x) = ( 8x - 3 ) / 8

Reverse the sign of the function.

f(x) = ( 8x + 3 ) / 8

Simplify the function.

f(x) = ( x + 3 / 8 ).

Therefore,  the inverse of the function is f(x) = 8x – 3 and g ( x ) = x + 3/8. The correct option is B.

Answer:

51

Step-by-step explanation:

Plug in 3 as x into the function:

g(x) = 9x + 24

g(3) = 9(3) + 24

g(3) = 27 + 24

g(3) = 51

g(x) = 9x + 24

g(3) = 9(3) + 24

g(3) = 27 + 24 = 51

g(3) = 51

Answer:

El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.

Step-by-step explanation:

Sabes que el número N(t) de animales vivos después de t años se predice mediante N(t) = 100*[tex]0.9^{t}[/tex]

Para estimar el número de animales vivos después de, por ejemplo, 1 año debes simplemente reemplazar el tiempo t por el tiempo correspondiente, en este caso 1 año:

N(1) = 100*[tex]0.9^{1}[/tex]

Resolviendo:

N(1) = 100*[tex]0.9^{1}[/tex]= 100*0.9= 90

De manera similar, podes estimar el número de animales vivos después de 5 y 10 años. Esto es, reemplazas t por 5 años:

N(5) = 100*[tex]0.9^{5}[/tex]= 100*0.59049= 59.049≅ 60

y t por 10 años:

N(10) = 100*[tex]0.9^{10}[/tex]= 100*0.3487= 34.86 ≅ 35

El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.

Answer:

26 5/32 in. or 2 ft

Step-by-step explanation:

Since we are taking into account 1/8in for each saw cut the total length of the 4 pieces of wood will be 3/8in less than the single long piece (3 cuts * 1/8).

Let's first convert the piece of wood to inches:

8 3/4ft = 8.75ft

8.75 ft *(12in./1ft) => 8.75 *12= 105 inches

Now we can subtract the 3/8in that will be lost from making 3 cuts:

105in. - 3/8in. = 104 5/8in.

So the total length of the 4 pieces of wood will be 104 5/8in.

Therefore, each piece will be (104 5/8in)/4 in length.

First let's convert 104 5/8in. to an improper fraction to make it easier to work with:

104 5/8in. = (104*8 + 5)/8in.

=837/8in.

Now we can divide this by 4 to get the length of each piece of wood:

(837/8in.)/4 is the same as (837/8in.)*(1/4)

Multiply numerators together, and multiply the denominators together:

(837/8in.)*(1/4) = 837/32in.

Convert back to a mixed number if needed:

837/32in.= 26 5/32in. or 2ft, 2 5/32in.

Answer:

See Explanation

Step-by-step explanation:

This question requires options.

Since, there are none, I'll answer on a general term.

For a coordinate point to be on the graph, the x and y value when substituted in the given equation must make the equation true.

Take for instance

(x,y) = (1,2)

This implies that

x = 1

y = 2

Substitute values of x and y in

y = 3x - 1

We have:

2 = 3 * 1 - 1

2 = 3 - 1

2 = 2

Notice that both sides of the equation are equal.

Hence

(1,2) lies on the xy coordinate plane.

However,

Take for instance (x,y) = (2,4)

This means

x = 2 and y = 4

Substitute values of x and y in

y = 3x - 1

4 = 3 * 2 - 1

4 = 6 - 1

4 ≠ 5

The above does not represent an equation because 4 is not equal to 5.

Hence, (2,4) does not lie on the coordinate plane

So, to answer your question, you need to substitute values of x and y in the given equation.

Which ever of the options that does not show equality answers your question.

Answer:

x = 2

Given :

∆GHI is an isosceles triangle with a vertex angle H.

m∠H=80°

To Find :

The m∠I.

Solution :

Since, H is the vertex angle.

So, m∠I = m∠G = x

We know, by angle sum property of triangle :

m∠I + m∠G + m∠H = 180°

2x + 80° = 180°

x = 50°

Therefore, m∠I = 50° .

The number of sheets of stickers is 12.25, and the number of bags of candy is 5.25 she will use.

It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign: between the numbers.

Allison uses 7 sheets of stickers and 3 bags of candy for every 8 friends.

It means the ratio of the sticker to candy bags:

7:3   for 8 friends

[tex]\frac{7}{8} :\frac{3}{8}[/tex]  for 1 friend or

0.875:0.375

If she makes 14 treat bags then:

The number of sheets of stickers she will use = 0.875×14 ⇒ 12.25

The number of bags of candy she will use = 0.375×14 ⇒ 5.25

Thus, the number of sheets of stickers is 12.25, and the number of bags of candy is 5.25 she will use.

Answer:

Option (3)

Step-by-step explanation:

w = [tex]\frac{\sqrt{2}}{2}[\text{cos}(225) + i\text{sin}(225)][/tex]

Since, cos(225) = cos(180 + 45)

                          = -cos(45) [Since, cos(180 + θ) = -cosθ]

                          = -[tex]\frac{\sqrt{2}}{2}[/tex]

sin(225) = sin(180 + 45)

             = -sin(45)

             = -[tex]\frac{\sqrt{2}}{2}[/tex]

Therefore, w = [tex]\frac{\sqrt{2}}{2}[-\frac{\sqrt{2}}{2}+i(-\frac{\sqrt{2}}{2})][/tex]

                      = [tex]-\frac{2}{4}(1+i)[/tex]

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

z = 1[cos(60) + i(sin(60)]

  = [tex][\frac{1}{2}+i(\frac{\sqrt{3}}{2})[/tex]

  = [tex]\frac{1}{2}(1+i\sqrt{3})[/tex]

Now (w + z) = [tex]-\frac{1}{2}(1+i)+\frac{1}{2}(1+i\sqrt{3})[/tex]

                   = [tex]-\frac{1}{2}-\frac{i}{2}+\frac{1}{2}+i\frac{\sqrt{3}}{2}[/tex]

                   = [tex]\frac{(i\sqrt{3}-i)}{2}[/tex]

                   = [tex]\frac{(\sqrt{3}-1)i}{2}[/tex]

Therefore, Option (3) will be the correct option.

Answer:

The 18th term of the arithmetic sequence will be:

[tex]a_{18}=37[/tex]

Step-by-step explanation:

We know that the arithmetic sequence with a common difference 'd' and the first term 'a₁' is defined as

[tex]a_n=a_1+\left(n-1\right)d[/tex]

Given the values

d = 2

a₁ = 3

As we have to determine the 18th term of the arithmetic sequence.

so putting n = 18 in the nth term to determine the 18th term.

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_{18}=3+\left(18-1\right)2[/tex]

     [tex]=3+17\cdot \:2[/tex]

     [tex]=3+34[/tex]

     [tex]=37[/tex]

Therefore, the 18th term of the arithmetic sequence will be:

[tex]a_{18}=37[/tex]
