i believe D because he's paying that money so he will have to add it.

also i had this question

Answer:

yay

Step-by-step explanation:

Answer:

1.50 is what percent of 32

what percent of 32 is 1.50 ?

Solution: 1.50 is what percent of 32 is equal to (1.50 / 32) x 100 = 4.69%. So if you buy an item at $32 with $1.50 discounts, you will pay $30.5 and get 4.69% discount cashback rewards so 4.69 is your answer

Answer:

Step-by-step explanation:

You can solve this by applying the fact that when an exponent is applied on top of a base raised to another exponent, those exponents can be multiplied:

Let's solve it:

[tex](4^3)^6 = 4^n\\4^{18} = 4^n\\n = 18[/tex]

Step-by-step explanation: r= 2 km c= 12.56 so 12.56

ALL LINES CAN BE REPRESENTED IN THE FORM [tex]f(x) = ax+b[/tex].

We know that:

[tex]f(1) = -5 \implies a\cdot(1)+b = -5 \implies a+b = -5[/tex]

and

[tex]f(3) = -17 \implies a\cdot(3) +b = -17 \implies 3a+b = 17[/tex]

Observe that:

[tex]3a+b = 2a+a+b = 2a+(a+b)[/tex]

So:

[tex]2a+(a+b) =-17[/tex]

But we know that [tex]a+b = -5[/tex], so:

[tex]2a+(a+b) =-17[/tex]

[tex]2a+(-5) = -17[/tex]

[tex]2a = -12[/tex]

[tex]a = -6[/tex]

Since:

[tex]a+b = -5[/tex]

[tex](-6)+b = -5[/tex]

[tex]b = 1[/tex]

So the line is:

[tex]f(x) = 1-6x[/tex]

Step-by-step explanation:

I'll just give you 2 examples if you need a better understanding tell me

1) 2 * 2/4

a. First make 2 --> 2/1 so it's a fraction

b. Multiply 2 by 2 giving you 4

c. Multiply 1 by 4 giving you 4

d. You'll get 4/4

e. Simplify to 1 by dividing by the numerator and denominator 4

Answer : 1

2) 3 * 4/6

a. First make 3 --> 3/1 so it's a fraction

b. Multiply 3 by 4 giving you 12

c. Multiple 1 by 6 giving you 6

d. You'll get 12/6

e. Simiply to 2 by dividing the numerator and denominator by 6

Answer : 2

Answer:

a. Yes it's a proportional relationship. It is because Distance is travelled uniformly.

b. Unit is m/min^2.

c. It means he is travelling in meters with minutes counting how far he have travelled.

Answer:

Part A)

5th and 6th Choices

Part B)

[tex]\displaystyle y=\frac{1}{4}x^2-x-4[/tex]

Step-by-step explanation:

We are given a parabola with focus at (2, -4) and the directrix given by y = -6.

Part A)

Since our directrix is an equation of y, the distance from any point (x, y) on the parabola to the directrix will simply be the absolute value of the difference of the y-values. Hence:

[tex]d_1=|y-(-6)|=|y+6|[/tex]

Again, we will use the distance formula. Let the point (x, y) be (x₂, y₂) and our focus (2, -4) be (x₁, y₁). Then by the distance formula:

[tex]d_2=\sqrt{(x-2)^2+(y-(-4))^2}=\sqrt{(x-2)^2+(y+4)^2[/tex]

Hence, our answers are the 5th and 6th choices.

Part B)

By definition, any point (x, y) on the parabola is equidistant to the focus and the directrix. Hence:

[tex]\sqrt{(x-2)^2+(y+4)^2}=|y+6|[/tex]

Square both sides. We may remove the absolute value as anything squared yields a positive. Hence:

[tex](x-2)^2+(y+4)^2=(y+6)^2[/tex]

Square:

[tex](x^2-4x+4)+(y^2+8y+16)=(y^2+12y+36)[/tex]

Rearrange:

[tex](x^2-4x+20)-(36)=(y^2-y^2)+(12y-8y)[/tex]

Combine like terms:

[tex]x^2-4x-16=4y[/tex]

Divide both sides by 4. Hence, our equation is:

[tex]\displaystyle y=\frac{1}{4}x^2-x-4[/tex]

no you are actually doing really good keep it up

Answer:

124 miles.

Step-by-step explanation:

From the question given above, the following data were obtained:

1 in = 20 miles

6 1/5 in =?

Next, we shall express 6 1/5 in decimal for easy calculation . This can be obtained as follow:

6 1/5 = 31 / 5

6 1/5 = 6.2 in

Finally, we shall convert 6.2 in to miles. This can be obtained as follow:

1 in = 20 miles

Therefore,

6.2 in = 6.2 in × 20 miles / 1 in

6.2 in = 124 miles

Thus, 6 1/5 in is equivalent to 124 miles.

Therefore, there are 124 miles between the two towns.

Answer: I think the first similar to KLM

Step-by-step explanation:

Answer:

2. The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6. It is that simple!

The domain is

✔ all real numbers

The range is

✔ all real numbers greater than or equal to –2
