Answer:

-1

Step-by-step explanation:

make it equal to zero

-9y - 9 = 0

add 9 to both sides

-9y = 9

divide both sides by -9 to get y alone

y = 9/-9

The value of g(h(10)) is 2√2. the correct option is A.

Given that the functions are g(x)=√x-4 and h(x)=2x-8.

A function is defined as the relationship between a set of inputs where each input has an output.

Firstly, we will find the value of h(10) by substituting x=10 in the function h(x)=2x-8.

h(10)=2(10)-8

h(10)=20-8

h(10)=12

Now, we will find g(h(10)) where h(10)=12.

By substituting h(10)=12 in g(h(10)), we get

g(h(10))=g(12).

Further, we will find g(12) by substituting x=12 in the function g(x)=√x-4, we get

g(12)=√(12-4)

g(12)=√8

g(12)=2√2

Hence, the value of function g(h(10)) when g(x)=√x-4 and h(x)=2x-8 is 2√2.

The equivalent expression is,

''Negative two over fifteen times x plus two''

What is Mathematical expression?

The combination of numbers and variables by using operations addition, subtraction, multiplication and division is called Mathematical expression.

We have to given the expression as;

''One fifth times the quantity 3 times x plus 10 end quantity minus 11 over 15 times x''

Now, Write in mathematical expression as,

⇒ [tex]\frac{1}{5} (3x + 10 ) - \frac{11}{15} x[/tex]

We can solve it as,

⇒ [tex]\frac{1}{5} (3x + 10 ) - \frac{11}{15} x[/tex]

⇒ [tex]\frac{3}{5} x + \frac{10}{5} - \frac{11}{15} x[/tex]

⇒ [tex]\frac{3}{5} x - \frac{11}{15} x+ 2[/tex]

⇒ [tex]\frac{-2}{15} x + 2[/tex]

Hence, It can be written as;

⇒ Negative two over fifteen times x plus two.

Therefore, The equivalent expression is,

The intersection of Sets :

The intersection of sets for two given sets is the set that contains all the elements that are common to both sets. The symbol for the intersection of sets is "∩''. For any two sets A and B, the intersection, A ∩ B (read as A intersection B) lists all the elements that are present in both sets, and are the common elements of A and B.

Intersections of sets have properties similar to the properties of numbers. The properties of the intersection of sets include the commutative law, associative law, the law of null set and universal set, and the idempotent law. The following table lists the properties of the intersection of sets.

Name of Property/Law Rule

Commutative Law A ∩ B = B ∩ A

Associative Law (A ∩ B) ∩ C = A ∩ (B ∩ C)

Law of ϕ and U ϕ ∩ A = ϕ , U ∩ A= A

Idempotent Law (A ∩ (B ∪ C) = (A ∩ B) ∪ (A ∩ C)

(A ∪ (B ∩ C) = (A ∪ B) ∩ (A ∪ C)

Important Notes:

(A ∩ B) is the set of all the elements that are common to both sets A and B.

If A ∩ B = ϕ, then A and B are called disjoint sets.

n(A ∩ B) = n(A) + n(B) - n(A ∪ B)

Given :

A = {1, 2, 3, 4, 5, 6, 7, 8, 9}

B = {2, 4, 6, 8, 10, 12}

Answer:

Step-by-step explanation: Let x be the smaller and y be the largest number.

Since x+y=13, we deduce y=13-x

Now, for the translation: "two more than the larger number" is y+2 , while "twice the smaller" is 2x

Their sum is y+2+2x

And since we know that y=13-x, we have y+2+2x=13-x+2+2=15+x

Step-by-step explanation:

Here,

angle B = 3 x angle A

angle C = 6 x angle A - 16

now, for a triangle,

angle A + angle B + angle C = 180

or, angle A + 3 x angle A + 6 x angle A - 16 = 180

or, 10 x angle A = 196

so, angle A = 19.6 degrees

angle B = 3 x 19.6 = 58.8 degrees

angle C = 6 x 19.6 - 16 = 101.6 degrees

The vertical distance of helicopter from the ground is equal to 2000 / 3 m.

Let the distance between the two planes A and B be x.

In △ ADC, we get that:

tan 60° = 2000 / y

√3 = 2000 / y  ...(1)

Now, in △ BCD, we get that:

tan 30° = 2000 - x / y

1 / √3 = (2000 - x) / y    ... (2)

Divide (1) from (2):

3 = 2000 / (2000 - x)

6000 - 3 x = 2000

3 x = 6000 - 2000

3 x = 4000

x = 4000 / 3

(2000 - x) = 2000 - 4000/3 = 2000 / 3

Therefore, the vertical distance of helicopter from the ground is equal to 2000 / 3 m.

The values of x, y, and z. The diagram is not to scale.

This is further explained below.

Generally, Angle in a triangle is 180^{\circ}

Therefore

45+68+x=180

x=180-(45+68)

x=67

The angle on a line is also 180^{\circ}

x+z =180

67+z =180

The number of vehicle administered by department A only = 18

The number of vehicle administered by department B only = 8

The number of vehicle administered by department C only = 1

Given data

50 vehicles belong to an enterprise that has three departments, A, B and C

6 vehicles are available for the use of all three departments

2 vehicles give service to neither of the departments

24 vehicles are administrated by department B

16 of the 24 used by B are also used by the others departments

There are twice as many vehicles in department A as there are in department C.

equal numbers of vehicles are allocated when used by any two departments

number of vehicles on department A = 2 * number of vehicles in department C.

say A = 2C

B = 24

let x represent the number of vehicles used by any two departments

16 of the 24 used by B are also used by the others departments and equal numbers of vehicles are allocated when used by any two departments hence

16 = 2x + 6

2x = 16 - 6

2x = 10

x = 5

B only = 24 - 2x - 6 = 18 - 2x = 18 - 10 = 8

A only = A - 2x - 6 = 2C - 10 - 6 = 2C - 16

C only = C - 2x - 6 = C - 10 - 6 = C - 16

adding up all the vehicles as allocated to get to the sum of 50

24 - 2x - 6 + A - 2x - 6 + C - 2x - 6 + x + x + x + 6 + 2 = 50

24 - 6 - 6 - 6 + 6 + 2 - 2x - 2x - 2x + x + x + x + A + C = 50

24 - 10 - 6x + 3x + 2C + C = 50

14 - 3x + 3C = 50

3C - 3X = 50 - 14

3C - 3(5) = 36

3C - 15 = 36

3C = 36 + 15 = 51

= x⁸.

PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction and is the main rule for simplifying expressions.

Simplification seems to be the process of substituting a mathematical expression with a simpler, usually shorter counterpart.

Designers employ simplification to make designs more memorable and instantly recognizable in logos, emblems, posters, computer icons, as well as other design applications.

Given :[tex]\frac{1}{\left(x^4\right)^{-2}}[/tex]

On simplifying we get:

Use  (aⁿ)ˣ  = aⁿˣ

so we get:

[tex]\frac{1}{X^{(4)(-2)}}[/tex]

=[tex]\frac{1}{x^{-8}}[/tex]

Use a⁻ⁿ = 1/aⁿ

Now:

= [tex]\frac{1}{\frac{1}{x^8}}\\=x^8[/tex]
