Answer:

The correct answer is option D.  -126  

Step-by-step explanation:

<u>Points to remember</u>

<u>Composite functions</u>

f(x) and g(x) be the functions then,

(f - g)(x) = f(x) - g(x)

<u>To find the value of (m - n)(-5)</u>

Let  m(x) = x³ and n(x) = √ (6 + x)

(m - n)(x) = m(x) - n(x)

 =  x³ - √( 6 + x)

(m - n)(-5) = m(-5) - n(-5)

 =  x³ - √( 6 + x)

 =  (-5)³ - √( 6 + -5)

 = -125 -  √1

 = -125 -1

 = -126

The correct answer is option D.  -126

A lot with a depth of 80 feet and an area of 4,800 square feet was sold for $350 per front foot. What was the total sales price?
stepladder [879]

Answer:

total sales price =  $21,000

Step-by-step explanation:

given data

depth = 80 feet

area = 4,800 square feet

sold = $350 per front foot

to find out

total sales price

solution

first we get here front feet that is the front length of a parcel

front feet  = \frac{area}{depth}   ...................1

front feet  = \frac{4800}{80}

front feet  = 60

so total sales price will be

total sales price = 60 × $350 per front foot

total sales price =  $21,000

PLEASE HELP!! <br> I need help on problems #5, #6, #9, #10<br> Picture attached <br> Thank you!
Romashka-Z-Leto [24]

Answer:

5. TS ≅ ML

6. ∠N≅∠U

9. m∠P = 80°

10. QR = 3

Step-by-step explanation:

The congruent symbol ≅ indicates that the two shapes have the same angle and side lengths.

5. TS are the third and second letter in RSTUV. The third and second letters in KLMNO are ML. TS ≅ ML

6. N is the fourth letter in KLMNO. The fourth letter is RSTUV is U. ∠N≅∠U

9. ∠P is congruent to ∠W. Notice they are both on the longer side and the wider angle. Since m∠P ≅ m∠W, and  m∠W = 80°, then m∠P = 80°

10. QR is congruent to XY. They are both the shortest sides of the shape. QR ≅ XY and XY = 3, then QR = 3

Does a trend line always pass through every point on a scatter plot?
forsale [732]
No, it does not and it's not supposed to.  A trend line is drawn to go through in the best way possible, to go through the "center" of the points as best as it can.  It may hit some of the points, but not all of them.  Generally, the idea is to try to get the trend line to have as many points "above" it as it does "below" it to say you've gone through them evenly.
