B. Determine the values of a and b so that f is continuous.<br><br> Please help!

Answer:

following are the solution to this question:

Step-by-step explanation:

Please find the complete question in the attached file.

$\lim_{x\to 2}+f(x) = \lim_{x\to 2}+ (ax^2-bx+3) = 4a-2b+3\\\\ \to 4a-2b+3 = 4\\\\ \therefore \ \ 4a-2b = 1\\\\$

The one-sided limits of F(x) at x = 3 must be equivalent for f(x) to be continuous at x = 3.

$\to \lim_{x\to 3}- f(x) = \lim_{x\to 3}- (ax^2-bx+3) = 9a-3b+3\\\\ \to \lim_{x\to 3}+ f(x) = \lim_{x\to 3}+ (2x-a+b) = 6-a+b\\\\$

So,

$\to 9a-3b+3 = 6-a+b\\\\\therefore\\ \to 10a -4b = 3$

$\to 4a - 2b = 1......(a)\\\to 10a - 4b = 3.......(b)\\$

In equation a multiply the by -2 and then add in the equation b:

$\to -8a + 4b = -2\\\to 10a - 4b = 3\\ \to 2a = 1\\\\ \to a = \frac{1}{2}\\\\ \to \ 4(\frac{1}{2}) - 2b = 1\\\\ \to 2 - 2b = 1\\\\ \to -2b = -1\\\\ \to b = \frac{1}{2}$

So, the value of $a \ and \ b= \frac{1}{2}$

telo118 [61]

According to the given values, the numbers from least to greatest is ∛64, 4.222.. √19

<h3>Descending and ascending order</h3>

Ordering a sequence of number from least to greatest is known as the ascending order of magnitude

Given the following parameters

∛64, √19 and 4.222...

The cube root of 64 is 4

The square root of 19 is 4.36

While the repeating decimal 4.2. can be 4.2222...

Simplify the following expression : 2 (2x-3)+5 (6x+1)

vivado [14]

To simplify begin by distributing the multiplication outside the parenthesis:
$2(2x-3)+5(6x+1) =4x-6+30x+6 \\ 4x+30x=34x$

Ms. Ashley planned to stay at a hotel that charges $88 per night for a room and $20 per night in fees and taxes. She used this e

Fudgin [204]

Step-by-step explanation:

Since 88 is for one night and 20 per night in fees and taxes.

Step 1 : Calculate for $88

$\frac{88n}{88} \\$ make N the subject of formula

$n = \frac{88}{88} \\$

N= 1

Step 2: Calculate for $20

$\frac{20n}{20} \\$

make N the subject of formula

$n = \frac{20}{20}$

N = 1
