Answer:

The last one.

Step-by-step explanation:

The last table because y = 5x   ( a = 5):

Answer:

B 360

Step-by-step explanation:

i have Mrs. Dunn

Sum of the measures of the exterior angles of a convex 55-gon is equal to  360.

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.

here, we have,

An exterior angle is an angle between a side of a polygon and an extended side adjacent to it.

A polygon refers to any closed curve comprised of a set of connected sides such that no two sides cross.

Convex 55-gon means a convex polygon with  n sides.

The sum of measures of any polygon is equal to 360

So, the sum of the measures of the exterior angles of a convex 55-gon is equal to 360.

Answer:

novel = 416

short story = 32

Step-by-step explanation:

13n + n = 448

n= 32

so novel has 32x13 = 416

short story has 32

416+32 = 448

Answer:

2.56

Step-by-step explanation:

The equation they dive u: d = 16t^2, so in the question they said what's the distance, d, if t = 0.4

So you just have to replace t with 0.4:

d = 16t^2

d = 16(0.4)^2

d = 16(0.16)

d = 2.56

Answer:

1/3

Step-by-step explanation:

-3 - -1= -2

3-9 = -6

-2/-6 = 2/6 = 1/3

Answer: 1/3

Step-by-step explanation:

slope = change in y / change in x

= (-3 - -1) / (3 - 9)

= -2 / -6

= 2/6

=1/3

Answer:

Slope = 3

Y Intercept = 3

Step-by-step explanation:

3x - y = 3

(subtract 3x from both sides - we have to get y by itself)

-y = -3x - 3

(divide by -1 from both side - we need to make y positive)

y = 3x + 3

The expression [tex]|-19|[/tex] has the smallest value.

Option A is correct.

The absolute value is always positive because absolute value represent distance from zero on number line.

And distance can not be negative.

Absolute value of given number shown below,

            [tex]|-19|=19\\\\|-34|=34\\\\|22|=22\\\\|47|=47[/tex]

Thus, the expression [tex]|-19|[/tex] has the smallest value.

Answer:

There are 2,000 grams left after 300 years.

Step-by-step explanation:

Giving the following information:

The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially.

First, we need to calculate the reduction of the substance each year:

Yearly reduction= 8,000/400= 20 grams per year

Now, for 300 years:

300 year reduction= 20*300= 6,000

There are 2,000 grams left after 300 years.

Answer:

18 1/4

Step-by-step explanation:

The easiest way to do this is to start at 0 and go 3 1/4 units to your right.

Then start at 0 and go -15 units to your left.  So far I have not used a formula because I want you to see intuitively what the answer is. Then we'll do it with a formula.

The total distance is 3 1/4 + 15 = 18 1/4. Purists will hate the way I've done it, but beginners should understand what they are doing.

A formula would look like this

distanace = sqrt( x2 - x1 )^2 + (y2 - y1)^2 )

distance = sqrt( (3 1/4 -  - 15)^2 + (4 - 4)^2 )

distance = sqrt(  (18 1/4 )^2 + 0)

distance = 18 1/4

Answer:

The answer is B. (-2, 0)

Step-by-step explanation:

x= 2 ⋅ cos(π) = −2

y=2 ⋅ sin(π) = 0

The rectangular coordinates is (-2 , 0) , Option B is the correct answer.

The equation for a polar point ( r, [tex]\rm \theta[/tex]) is

x = rcos [tex]\rm \theta[/tex]

y =r sin  [tex]\rm \theta[/tex]

where (x , y)  are rectangular coordinates.

The polar coordinate given is ( 2 , π)

r = 2

[tex]\rm \theta[/tex] = π

so

x = 2 cos π

x = 2 * (-1)

x = -2

y = 2 sin π

y = 2 *0

y = 0

Therefore the rectangular coordinates is (-2 , 0) , Option B is the correct answer.
