Answer: D) 10 sin (πx) - 5

Step-by-step explanation:

The range (maximum - minimum) is 5 - (-15) = 20

The amplitude (A) is range (20) ÷ 2 = 10

The vertical shift (D) is maximum (5) - amplitude (10) = -5

Of the given options, only A & D are candidates. Now we need to decide if it is a cos graph (A) or a sin graph (D). If we shift the graph up 5 units (to eliminate the vertical shift) , the graph would pass through the origin. Thus it is a sin graph and the answer must be option D.

True or false : 20÷4x5= 1 10+10÷2=15 6+4×5=50 12_3×2=6 81÷9+2=11

ELEN [110]

To solve, you must use order of operations. The acronym used is BEDMAS (brackets, exponents, division/multiplication, addition/subtraction), which is the order you solve in.

F 20÷4x5
 =5x5
 =25

T 10+10÷2
=10+5
=15

F 6+4×5
=6+20
 =26

T 81÷9+2
=9+2
=11

A line segment has endpoints at (2,10) and (10,2). What are the coordinates of the midpoint of the line segment?

IrinaVladis [17]

Answer:

(6,6)

Step-by-step explanation:

The midpoint formula is $(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )$ . Substitute (2,10) and (10,2) into this formula and simplify.

$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} ) \\(\frac{2+10}{2},\frac{10+2}{2} ) \\(\frac{12}{2},\frac{12}{2} ) \\(6,6)$
