Warren’s tape measure is marked in increments of 1/16 inch, not in decimal numbers. To measure the tiles, he needs to know the s

ide lengths to the nearest 1/16 inch. In this activity, you will convert decimal values to fractional values and then calculate the area of the tiles. The length of tile A is about 2.23607 inches. Which mark on the tape measure is closest to 2.23607 inches? Remember, the tape measure is marked in sixteenths of an inch.

How does solving a linear system in two variables compare to solving an equation in one variable?
yan [13]

In this case, we must analyze the question to find the solution.

Step 01:

equation one variable vs system of equations two variables = ?

Step 02:

In an equation with one variable, we must only apply the algebraic rules to find its value.

For systems of equations, we have different methods to solve them.

And it is possible to write the equations as a function of one variable, and then substitute in the other equation and thus find the solution.

Therefore, it is comparable to solving one variable equation.

That is the answer.

Can someone help me with this and show me how to do it?

9514 1404 393

Answer:

  5i) f(x) = 3·13^x +5

  5ii) f(x) = -6·(1/2)^x +5

  6) f(x) = 3·8^x -1

  9a) (1, 0), (0, -3)

  9b) (2, 0), (0, 8)

Step-by-step explanation:

5. The horizontal asymptote is y = c. To meet the requirements of the problem, you must choose c=5 and any other (non-zero) numbers for 'a' and 'b'. (You probably want 'b' to be positive, so as to avoid complex numbers.)

i) f(x) = 3·13^x +5

ii) f(x) = -6·(1/2)^x +5

__

6. You already know c=-1, so put x=0 in the equation and solve for 'a'. As in problem 5, 'b' can be any positive value.

  f(0) = 2 = a·b^0 -1

  3 = a

One possible function is ...

  f(x) = 3·8^x -1

__

9. The x-intercept is the value of x that makes y=0. We can solve for the general case:

  0 = a·b^x +c

  -c = a·b^x

  -c/a = b^x

Taking logarithms, we have ...

  log(-c/a) = x·log(b)

  \displaystyle x=\frac{\log\left(-\dfrac{c}{a}\right)}{\log(b)}=\log_b\left(-\dfrac{c}{a}\right)

Of course, the y-intercept is (a+c), since the b-factor is 1 when x=0.

a) x-intercept: log2(6/3) = log2(2) = 1, or point (1, 0)

   y-intercept: 3-6 = -3, or point (0, -3)

b) x-intercept: log3(9/1) = log3(3^2) = 2, or point (2, 0)

  y-intercept: -1 +9 = 8, or point (0, 8)

_____

<em>Additional comment</em>

It is nice to be comfortable with logarithms. It can be helpful to remember that a logarithm is an exponent. Even so, you can solve the x-intercepts of problem 9 using the expression we had just before taking logarithms.

  a) 6/3 = 2^x   ⇒   2^1 = 2^x   ⇒   x=1

  b) -9/-1 = 3^x   ⇒   3^2 = 3^x   ⇒   x=2

Write 63 as a product of prime factors in ascending order. I don't need the answer but the explanation as to my friends one was
seropon [69]

Answer:

Step-by-step explanation:

63=  3 * 3 * 7

63 will come in 7th table. 7*9. here 7 is a prime and 9 is composite number. 3*3 = 9. So 63 = 3*3*7
