Answer:

So the answer is the 3rd one or 1/16

Step-by-step explanation:

You can't have a negative exponent. To get rid of the negative exponent, you change it to 1/16

Answer:

1/16

Step-by-step explanation:

because 4^-2 equals 0.0625 in simplest form is 1/16

The proof here would be based on the use of the Pythagoras theorem in trigonometry.

In a triangle getting the altitude or height will result to producing a right angled triangle. In trigonometry, a right angled triangle have the sides as the hypotenuse, the adjacent and the opposite. in this case the altitude is either the opposite or adjacent.

From Pythagoras Theorem, the hypotenuse. equals the square root of the sum of squares of the other two sides. hence is the longer side. Each leg of this triangle would be shorter than the hypotenuse. The two sides that meet at the vertex are the adjacent or the opposite and the hypotenuse.

The table that represents a function is 1:2, 2:4, 3:6, 4:2.

Option 2 is the correct answer.

Given,

Function table:

1. 1 → 4,  2 → 2, 3 → 4,  2 → 6

2. 1 → 2, 2 → 4, 3 → 6, 4 → 2

3. 2 → 6, 0 → 4, 1 → 6, 2 → 2

4. 2 → 2, 3 → 2, 4 → 6, 3 → 6

We need to find which one is a function.

A function has an input and an output.

We can have different inputs and the same output.

Example:

f(x) = x²

x = 1, -1 are the inputs

f(1) = 1

f(-1) = 1

- We see that we have the same output 1 with different inputs 1 and -1.

i.e Many to one

- But we can not have the same inputs and different outputs.

i.e One to many

- We can have one-to-one in a given function.

We have,

1. 1 → 4,  2 → 2, 3 → 4,  2 → 6

Here,

2 → 2 and  2 → 6 = one to many.

We have the same inputs but different outputs which is not possible.

It is not a function.

2. 1 → 2, 2 → 4, 3 → 6, 4 → 2

Here,

1 → 2 and 4 → 2 =  many to one

2 → 4 and 3 → 6 = one to one

It is a function.

3. 2 → 6, 0 → 4, 1 → 6, 2 → 2

2 → 6 and 2 → 2 = one to many

This is not possible.

It is not a function.

4. 2 → 2, 3 → 2, 4 → 6, 3 → 6

3 → 2 and  3 → 6 = one to many

This is not possible.

It is not a function.

Thus the table that represents a function is 1:2, 2:4, 3:6, 4:2.

Option 2 is the correct answer.

Step-by-step explanation:

Answer:

y - 4= -2(x - 2)

Step-by-step explanation:

(This answer is in point slope form, if you need the answer in a different form like slope intercept, you would have to distribute the negative 2 and bring the negative 4 to the right side.)

So, you know the line is parallel to the equation y= -2x + 10. We know that parallel lines must have the same slope, so the answer will have a slope of negative 2. Because they have given you a point that the line passes through, we are going to put the answer in point slope form. we know a point and we know the slope, hence it is called point-slope.

Point slope form is y - y₁ = m(x - x₁). The m stands for the slope, and the x₁ and y₁ is where you will plug in the x and y coordinates (2,4) .

So to plug in the numbers into point slope form it would be y - 4 = -2 (x - 2). hope this helped :)

Answer:

12

Step-by-step explanation:

The Transitive Property states that if one quantity equals a second quantity, and the second quantity equals a third quantity, then the first quantity equals the third quantity.

Using Transitive Property, it is found that b + 3 is equal to 12.

The Transitive Property states that if one quantity equals a second quantity, and the second quantity equals a third quantity, then the first quantity equals the third quantity.

Given;

If a +5 = b + 3 and a + 5 = 12, then we need to find b +3=

So, a + 5 = 12

and a +5 = b + 3

Then b + 3 is also equal to 12. (Transitive Property )

Therefore, Using Transitive Property, it is found that b + 3 is equal to 12.

Given :

Devon purchased a new car valued at $16,000 that depreciated continuously at a rate of 35%.

Its current value is $2,000.

To Find :

Age of car.

Solution :

Price of car after 1 year :

[tex]P_1=P_o(1-0.35)[/tex]

Price of car after 2 year :

[tex]P_2=P_1(1-0.35)\\\\P_2=[P_o(1-0.35)](1-0.35)\\\\P_2=P_o(1-0.35)^2[/tex]

So, price of car after n years.

[tex]P_n=P_o(1-0.35)^n[/tex]

[tex]2000=16000(1-0.35)^n\\\\0.65^n=0.125\\\\n\times log(0.56)=log(0.125)\\\\n=\dfrac{log(0.125)}{log(0.56)}\\\\n=3.58[/tex]

Therefore, age of car in nearest whole number is 4 years.

Hence, this is the required solution.

Answer:

Cost of ride ticket = $5

Cost of game ticket = $4

Step-by-step explanation:

Given that:

Let ;

game ticket = g

Ride ticket = r

Jacob :

6g + 3r = 39 - - - (1)

Emily :

2g + 2r = 18 - - - - (2)

Divide (2) b y 2

g + r = 9 - - - - (3)

From (3)

g = 9 - r

Substitute ; g = 9 - r into (1)

6(9 - r) + 3r = 39

54 - 6r + 3r = 39

54 - 3r = 39

-3r = 39 - 54

-3r = - 15

r = 5

Put r = 5 in (g = 9 - r)

g = 9 - 5

g = 4

Hence,

Cost of ride ticket = $5

Cost of game ticket = $4
