Which relation is a function?
o {(4,0),(4,1),(4,2), (4,3)}
o {(7,4), (8,8), (10,8), (10,10)}
o {(-1,3), (-2,6),(0,0),(-2,-2)}
o {(2,2), (1,1),(0,0), (-2,-2)}
Given:
Different relations in the options.
To find:
The relation which is a function.
Solution:
A relation is a function if there exist unique output for each input value. In other words, there exist only one y-value for each x value.
In option A, [tex]y=0,1, 2, 3[/tex] for [tex]x=4[/tex]. So, this relation is not a function.
In option B, [tex]y=8, 10[/tex] for [tex]x=10[/tex]. So, this relation is not a function.
In option C, [tex]y=6, -2[/tex] for [tex]x=-2[/tex]. So, this relation is not a function.
In option D, all x-values are different. So, their exist unique output for each input value. It means this relation is a function.
Therefore, the correct option is D.

Answer:
It's [tex]3x^4+22x^3+31x^2-6[/tex]
Step-by-step explanation:
Area is L times width
LW=H
and the length is [tex]3x^2+4x-1[/tex] times the width [tex]x^2+6x+3[/tex]
basically you multiply yhem togetheer and combine like terms and voila
The answer is 3x^4 + 24x^2 - 6
explanation:
A = l × w
= (3x^2+4x-2)(x^2+6x+3)
=(3x × x) + (4x×6x) + (-2×3)
= 3x^2 + 24x^2 - 6

Answer:
x=10
Step-by-step explanation:
To solve for x, you need to draw an imaginary line connecting the right end of side x to the left side with length 15. This forms a triangle with side lengths 6 and 8, and hypotenuse x. Using the Pythagorean Theorem to solve for x, we get 6^2 + 8^2 = x^2, 36 + 64 = 100, [tex]\sqrt{100}[/tex] = 10.
Answer:
It's 10
Step-by-step explanation:
C^2=A^2+B^2blank
C=√(A^2+B^2)
If c is x and a and b are the side lengths the we can use Pythagoras's theorem to calculate the length of the line. A=6 B=8 and in the end when you calculate all that doohickey stuff you get x=10
Divide: 5 + 2i by 3 + 4i.
Answer:
1-2i
Step-by-step explanation:
Divide: 5 + 2i by 3 + 4i.
Given data
5 + 2i by 3 + 4i.
We have the expression as
(5 + 2i)/(3 + 4i)
Rationalize the denominator
(5 + 2i)/(3 + 4i)* (3 -4i)/(3 -4i)
=(5*3-20i+6i-8i^2)/9-12i-12i+16i^2
=15-14i+8/9-16
=7-14i/-7
=1-2i

Answer:
x = √17 exact answer
x ≈ 4.12 decimal approximation
Step-by-step explanation:
a² + b² = c²
x² + 8² = 9²
x² + 64 = 81
x² = 17
Take the square root of both sides
x = √17 exact answer
x ≈ 4.12 decimal approximation
SOMEONE HELP, I HAVENT BEEN PAYING ATTENTION TO CLASS
Answer:
A=4cm
ok to do this we do the formula
A=PiR^2
A=3.14*4^2
A=3.14*16
A=50.24
and the area of circle B is 4 times the area of a so
50.24*4=200.96
200.96=3.14*X^2
Since r is on the right side of the equation, switch the sides so it is on the left side of the equation. 3.14 ⋅ r 2 = 200.96 Divide each term by 3.14 and simplify.
r 2 = 64
r=8
CIRLCE A=50.24
CIRLCE B=8

Round off 2/3 correct to 2 significane figures
=====================================================
Explanation:
Use of a calculator will show that
2/3 = 0.6666...
where the 6's go on forever. Your teacher only wants 2 significant figures though. That means you'll round to the nearest hundredth to get 0.67
The 0 to the left of the decimal point is not a significant figure. The reason being is because we can rewrite 0.67 into 6.7*10^(-1); we can see the coefficient 6.7 having two sig figs.
Un hombre compra un caballo por 50 dolares. Vende el caballo por 70 dolares. Despues vuelve a compar el caballo por 80 dolares. Y vuelve a venderlo de nuevo por 90 dolares. Al final, ¿cuanto obtuvo de ganancia?

Step-by-step explanation:
En la primera transacción, el hombre está perdiendo 50 dólares:
1. -50 dólares
En la segunda transacción, el hombre gana 70 dólares:
2. -50 + 70 = +20 dólares
En la tercera transacción pierde 80 dólares:
3. 20 - 80 dólares = -60 dólares
Y en la última transacción, la ganancia es de 90 dólares. Así, la ganancia neta es:

Answer:
9/7 =a
Step-by-step explanation:
9 / -a + 15 = 8
Subtract 15 from each side
9 / -a + 15 -15 = 8-15
9 / -a = -7
Multiply each side by -a
9/-a * -a = -7 * -a
9 =7a
Divide each side by 7
9/7 = 7a/7
9/7 =a
Answer:
9 / 7 = a
Step-by-step explanation:
9 / - a + 15 = 8
Determined the defined range
9 / ( - a ) + 15 = 8 , a ≠ 0
subtract 15 from each side
9 / - a + 15 - 15 = 8 - 15
calculate the difference
9 / - a = - 7
multiply both side of equation by - a
9 / - a × - a = - 7 × - a
9 = 7 a
divide each side by of equation by 7
9 / 7 = 7 a / 7
9 / 7 = a

What is the area❓ No links or troll answers you’ll be reported
Answer:
103
Step-by-step explanation:
Find the area of the rectangle on the top
A = 7*13 = 91
Now find the area of the rectangle on the bottom
13 - (5+5) = 3
11-7 = 4
The dimensions of the bottom rectangle are 3 by 4
A = 3*4 = 12
The total area is 91+12 = 103
