Answer:

14.  27

16.  170

Step-by-step explanation:

We must follow Order of Operations rules here.  Work inside parentheses must be done first, then exponentiation, then multiplication and division, and finally addition and subtraction.

((5·7) - (8·4))³ becomes (35 - 32)³, or 3³, or 27.

16.  7² + ((46 - 7·2) + 2³)² becomes 7² + ((46 - 49) + 8)²

Again, do the work inside parentheses first:

7² + (3 + 8)² becomes 49 + 11², or 49 + 121, or, finally, 170

Do the functions have the same concavity?
Vesna [10]

Answer:

Step-by-step explanation:

Function f is graphed. The positive x-axis contains point c. The graph consists of an N-shaped curve. The curve starts in quadrant 3, moves upward concave down to a point in quadrant 1, moves downward concave down to point c in quadrant 1, continues downward concave up to a point in quadrant 4, moves upward concave up and ends in quadrant 1. The curve is purple to the left of point c, where it is concave down, and is green to the right of point c, where it is concave up.

Notice how fff is \purpleC{\text{concave down}}concave downstart color #aa87ff, start text, c, o, n, c, a, v, e, space, d, o, w, n, end text, end color #aa87ff to the left of x=cx=cx, equals, c and \greenD{\text{concave up}}concave upstart color #1fab54, start text, c, o, n, c, a, v, e, space, u, p, end text, end color #1fab54 to the right of x=cx=cx, equals, c.

PROBLEM 1

Let fff be a twice differentiable function. This is the graph of its second derivative, f''f  

′′

f, start superscript, prime, prime, end superscript.

Function f double prime is graphed. The x-axis goes from negative 8 to 8. The graph consists of a wave-shaped curve. The curve starts at (negative 8, 0), moves downward concave up to (negative 5, negative 5), moves upward concave up to (negative 2, 0), continues upward concave down t

I need to know how to do this ASAP

Note how angle GFE forms a right angle, which is 90 degrees.
Since the line cuts that angle into two smaller angles, intuitively, these angles add up to 90 degrees.

So, we can say that 2x + 3x = 90 (angle sum of right angle)
5x = 90
x = 18 degrees

The ratio of the perimeters of two similar triangles is 4:7. The sides of the larger triangles are 10, 12, and 13cm,
rjkz [21]

Answer:

Perimeter = 20cm

The perimeter is 35 for the larger triangle = 7:4 ratio

the perimeter for the smaller triangle = 4:7 ratio

We add up 4+7 = 11 and multiply 35 x 2 = 70.

so that the smaller triangle = 40  = 40:70

35 = 7 and 20 = 4

To find measurements of 20

we have any number over 10 combined will make the smaller sides possible,

Where hypotenuse would be under 10.

H = 6.5 Sides = 6 + 5 does not add up to 20

H = 9 Sides = 7 + 4  does have near equal spaced symmetry.

H = 9  Sides = 5 + 6  is wrong as no symmetry in measure

H = 8  Sides = 7 + 5 is wrong as no symmetry in measure

H = 7 Sides = 6 + 7  is wrong as equal sides

H = 6 sides = 6.5 + 6.5 is wrong as equal sides

H = 11 Sides = 6 + 3 is wrong has no symmetry.

The measurements must be 9cm, 7cm and 4 cm for the smaller triangle

The perimeter adds up to 20cm.

Use the distributive property to show why the product (-6)(-3) is positive.
Bumek [7]
<h2>Answer:</h2><h2>The product of (-6) (-3) by distributive property is 18</h2>

Step-by-step explanation:

Distributive properties are used in arithmetic multiplication and division to reduce the time and to answer faster.

(-6) (-3) can be written as (-6) (-2 (+) -1)

By distributive property of multiplication

(-6) (-2 (+) -1) ={ (-6) (-2) + (-6) (-1) }

     = { 12 + 6} = 18

since the product of ( - ) ( - ) = ( + )

multiplying two negative number gives a positive number.

Therefore the answer is 18.
