Answer:

6.4 miles

Step-by-step explanation:

5^2 + 4^2 = d^2

25 + 16 = d^2 = 41

d = 6.40 miles

The nearest tenth of a mile from your starting point is 6.4.

The Pythagoras theorem states that if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides.

To round a number to the nearest tenth, we need to look to the right of the tenths place, which is the hundredths place. If the digit in the hundredths place is 5 or greater than 5, we need to add one to the digit in the tenths place. If it is 4 or less than 4, the tenths place digit remains the same. All the digits to the right of the tenths place should be changed to 0. That means, while rounding off a number to the nearest tenth, we will stop the rounding at the tenths place.

According to the question

If you drive 5 miles east and then 4 miles south

We have to find the nearest tenth of a mile from your starting point

From the diagram, we have to use Pythagoras theorem

D = [tex]\sqrt{4^{2} +5^{2} }[/tex]

D = [tex]\sqrt{16+25}[/tex]

D = [tex]\sqrt{41}[/tex]

D = 6.40312

Round 6.40312 to the required nearest tenth

D = 6.4

Hence, The nearest tenth of a mile from your starting point is 6.4.

Answer: B) No; the remainder is 234, so (x+3) is not a factor.

===============================================================

Explanation:

We'll use the remainder theorem. That theorem says if we divide p(x) over (x-k), then the remainder is p(k). A special case of this theorem says that if we get 0 as the remainder, then (x-k) is a factor of p(x).

We're dividing f(x) over (x+3) which means that k = -3. Think of x+3 as x-(-3) so you can match it up with the form x-k.

To find the remainder of f(x)/(x+3), we need to compute f(-3).

Plug x = -3 into the f(x) function to get...

f(x) = 4x^3 + 11x^2 - 75x + 18

f(-3) = 4(-3)^3 + 11(-3)^2 - 75(-3) + 18

f(-3) = 234

The remainder is 234, which is isn't zero, so (x+3) is not a factor of f(x).

Answer:

No; the remainder is 0 so (x + 3) is not a factor

In this case, it is:

[tex]sin(26) = \frac{17}{x}[/tex]

Make x the subject

Answer:

1) Function

2) Set Notation

3) Domains: {-4, -2, -1, 1, 3, 4}

4) Ranges: {-3, -2, 0, 2, 3}

Step-by-step explanation:

1) This is a function because the x-values are NOT repeated, and it passes the vertical line test.

2) This is a set notation because it has the symbol --> {    } and it is "help define the elements of a set." You can search up "set notation" and you would get the idea. However, this is not an inequality because in inequality you would have, ex: x < 4 ≤ x

3) Domains mean the x-intercept. Remember to list domains from least to greatest!

4) Range means y-intercept. Remember to list the ranges from least to greatest! If a range is repeated then you do NOT need to re-write that number again.

Answer: (2x - 1)(3x - 4)

(split -11x as -8x and -3x)

Step-by-step explanation:

I am assuming that it is actually 6x^2 - 11x + 4

To find out how to split the middle term: The two numbers should multiply to a*c (6*4 = 24) and add to b (-11)

-8, -3 works

(6x^2 - 8x) + (-3x + 4)

2x(3x - 4) + -1(3x - 4)

(2x - 1)(3x - 4)
