2. Jenny is trying to work out a problem and showed her friend, Laila, her work. Laila found there was a mistake in one of the s

teps.
Which step did Jenny make a mistake on? Identify the mistake and explain why it is a mistake.

4^(2x+8)= (1/256)^(3x+5)
4^(2x+8)= (4^4 )^(3x+5)
4^(2x+8)= 4^(12x+20)

Next, correct the mistake and solve for x and justify each step.

Find an equation of the tangent line to the graph of
lakkis [162]

Answer:

y + 4 = -3 (x - 5)

In other words,

y = -3 x + 11

Step-by-step explanation:

The slope of the tangent line to y = g(x) at x = 5 is the same as the value of g'(x). g'(5) = 3. Therefore, 3 will be the slope of the tangent line.

The tangent line goes through the point of tangency (5, g(5)). g(5) = -4. Therefore, the tangent line passes through the point (5, -4).

Apply the slope-point form of the line. The equation for a line with slope <em>m</em> that goes through point (a, b) will be y - b = m(x - a). For the tangent line in this question,

  • m = 3,
  • a = 5, and
  • b = -4.

What will be the equation of this line?

Gala2k [10]

Answer:

37.8

Step-by-step explanation:

Set up a proportion using the values given in the diagram of similar triangles.

31.5/15 = x/18

Cross-multiply.

31.5(18) = 15x

Multiply.

567 = 15x

Divide both sides by 15.

37.8 = x

Let A = R−{0}, the set of all nonzero real numbers, and consider the following relations on A × A. Decide in each case whether R
andre [41]

Answer:

Step-by-step explanation:

Let A = R−{0}, the set of all nonzero real numbers, and consider the following relations on A × A.

Given that (a,b) R (c,d) if ad=bc

Or (a,b) R (c,d) if determinant

\left[\begin{array}{ccc}a&b\\c&d\end{array}\right] =0

a) Reflexive:

We have (a,b) R (a,b) because ab-ab =0 Hence reflexive

b) Symmetric

(a,b) R (c,d) gives ad-bc =0

Or da-cb =0 or cb-da =0 Hence (c,d) R(a,b). Hence symmetric
