Answer:

14.04

Step-by-step explanation:

[tex]19^{2}[/tex] - [tex]17^{2}[/tex] = 72

Write an equation for the line that passes through (-8.5, 11) and (5, -2.5).

Answers

9514 1404 393

Answer:

  y = -x + 5/2

Step-by-step explanation:

The 2-point form of the equation of a line can be useful.

  y = (y2 -y1)/(x2 -x1)/(x -x1) +y1

  y = (-2.5 -11)/(5 -(-8.5))/(x -(-8.5)) + 11

  y = -13.5/13.5(x +8.5) +11 . . . . . . simplify a bit

  y = -x +2.5 . . . . . write in slope-intercept form

How are geometric sequences similar to arithmetic sequences? How are they different?

Answers

The differences between arithmetic and geometric sequences is that arithmetic sequences follow terms by adding, while geometric sequences follow terms by multiplying. The similarities between arithmetic and geometric sequences is that they both follow a certain term pattern that can't be broken. There you go

Answers

9514 1404 393

Answer:

  B.  The area of P is 9 times the area of Q.

Step-by-step explanation:

The areas of similar figures are related by the square of the scale factor of their linear dimensions. The ratio of side lengths is ...

  side of P : side of Q = 6 : 2 = 3 : 1

So, the ratio of areas is ...

  area of P : area of Q = 3² : 1² = 9 : 1

The area of P is 9 times that of Q.

PLEASE YELP IM ON A TEST!!!

Answers

Percents to a decimal is easier to understand just take the percent so say it is 35% the decimal form would be .35 or 5% .05, and for the percent to a fraction just take the percent such as 30/100 and make sure it is in the simplest form to solve so that would be 3/10.

The expression (3x^7)^4 is equivalent to cx^n.What is the value of c?

Answers

Answer: It’s 81

Step-by-step explanation:

I think it’s 81 because u use the distributive property (xy)^a=x^a y^a

and in the situation you change it into 3^4(x^7)^4 and u simplify 3^4 and get 81 and then just multiply 7 and 4 and your answer is 81x^28. 81 is c in the equation

We want to find an equivalent expression to  (3x^7)^4 of the form cx^n, and we want to find the value of c.

The equivalent expression is:

[tex]81*x^{28}[/tex]

So the value of c is:

c = 81.

First, we need to remember two properties of exponents.

The exponents are distributive under multiplications.

And we know that:

[tex](a^n)^m = a^{n*m}[/tex]

Using these two properties, we can rewrite:

[tex](3x^7)^4 = (3^4)*(x^{7*4}) = 81*x^{28}[/tex]

So the equivalent expression is:

[tex]81*x^{28}[/tex]

Then we have c = 81.
