Answer:

49.02 > 49.019

Step-by-step explanation:

It's true :)

Think of 49.02 as 49.020.

Don't you think that 49.020 > 49.019? It makes sense! :)

Let A = { x ∈ R : x 2 − 5 x + 4 ≤ 0 } , B = (3 , 5), and C = (3 , 4]. Show that A ∩ B = C . (Recall, you must show two separate

Answer:

You can proceed as follows:

Step-by-step explanation:

First solve the quadratic inequality $x^{2}-5x+4\leq 0$ . To do that, factorize, then we have that $(x-4)(x-1)\leq 0$ . This implies that

$x-1\leq 0\, \text{and}\, x-4\geq 0$

$x-1 \geq 0\, \text{and}\, x-4\leq 0$

In the first case the solution is the empty set $\emptyset$ . In the second case the solution is the interval $1\leq x \leq 4$ . Now we have that

$A=[1,4]$

$B=(3,5)$

$C=(3,4]$ .

To show that $A\cap B\subseteq C$ consider $x\in A\cap B$ . Then $1\leq x \leq 4\, \text{and}\, 1$ , this implies that $3$ , then $x\in C$ . Now, to show that $C\subseteq A\cap B$ consider $x\in C$ , then $3$ , then $1\leq x \leq 4\, \text{and}\, 3$ , then $x\in [1,4] \, \text{and}\, x\in (3,5)$ , this implies that $x\in A\cap B$ .

Terry has an investment account which compounds interest continuously at an annual interest rate of 1. 4%. After 3 years, he has

Serggg [28]

Answer:

$1,630.08

Step-by-step explanation:

The value of an amount earning interest continuously compounded is given by the formula ...

A = Pe^(rt)

The value of P can be found by dividing by its coefficient:

P = A/(e^(rt)) = Ae^(-rt)

P = $1700·e^(-0.014·3) ≈ 1630.0786

Terry placed $1,630.08 in the account.

The black graph is the graph of y= f(x). Choose the equation for the red graph

antiseptic1488 [7]

Answer:

$D$

Step-by-step explanation:

Notice that the red graph does not globally differ from the black graph: it would have been approximately the same one unless it had been displaced by 3 units up. Therefore, it was only the ordinate axis that underwent our change: $y - 3 = f(x) \Leftrightarrow y = f(x) + 3$ .
