The regular octagon ABCDEFGH rotates 135º clockwise about its center to form octagon A′B′C′D′E′F′G′H′. Point A′ of the image coincides with point of the preimage. Point B′ of the image coincides with point of the preimage.

Answers

Answer:

The point A′ of the image coincides with point D of the preimage. The point B′ of the image coincides with point E of the preimage.

Step-by-step explanation:

It is given that regular octagon ABCDEFGH rotates 135º clockwise about its center to form octagon A′B′C′D′E′F′G′H′.

It means the central angle divided in 8 equal parts. The central angle between two consecutive vertices is

$(360)/(8)=45^(\circ)$

The regular octagon ABCDEFGH rotates 135º clockwise.

$A=F'$

$B=G'$

$C=H'$

$D=A'$

$E=B'$

$F=C'$

$G=D'$

$H=E'$

Therefore the point A′ of the image coincides with point D of the preimage. The point B′ of the image coincides with point E of the preimage.

Answer:

Point A' will coincide D and B' will coincide with E.

Step-by-step explanation:

In the figure attached we have regular octagon ABCDEFGH. It's a regular octagon means all it's sides are equal and central angle of one sector out of 8 sectors formed will be = $(360)/(8)=45$

Now this octagon is rotated about it's center to form new octagon A'B'C'D'E'F'G'H'

Since angle of rotation is 135° clockwise which means octagon is rotated by 45×3 = 3×(central angle of one sector)

After rotation clockwise new image will coincide like this

A = F'

B = G'

C = H'

D = A'

E = B'

F = C'

G = D'

H = E'

Now we can easily tell that point A' will coincide with the point D of preimage. Similarly point B' of the image will coincide with the point E.

If you needed to triple a recipe would the rate change? Please explain

Answers

Yes the rate would changed because you increased the size of the recipe.

No. This is because it is proportional/equivalent. For Example 1 cup of flour for 2 cups of sugar is the same as 3 cups of flour for 6 cups of sugar

over the last 50 years, the average temperature has increased by 2.5 degrees worldwide. what is the rate of change in worldwide temperatures per year?

Answers

Answer:

0.05 degrees per year

The graph shows Linda's math scores versus the number of hours spent doing math homework.What will most likely be Linda's approximate math score if she does math homework for 7 hours a week?

A. 62.5 Points

B.77.5 Points

C. 82.5 Points

D.93.5 Points

Answers

Answer:

The approximate score is:

Option: A

A. 62.5 points.

Step-by-step explanation:

Clearly from the graph we could observe that the line of best fit passes through (0,10) and (4.5,45).

Now we find the equation of line of best fit with the help of formula that is used to find the equation of a line passing through (a,b) and (c,d) as:

$y-b=(d-b)/(c-a)* (x-a)$

Here we have:

(a.,b)=(0,10) and (c,d)=(4.5,45)

Hence, the line of best fit is given as:

$y-10=(45-10)/(4.5-0)*(x-0)\n\ny-10=(35)/(4.5)* x\n\ny-10=(70)/(9)* x\n\ny=(70)/(9)* x+10$

Now we are asked to find the math score if she does math homework for 7 hours a week i.e. we have to find the value of y when x=7.

Hence, we put x=7 in the equation to obtain y as:

$y=(70)/(9)* 7+10\n\ny=(490)/(9)+10\n\ny=64.44$

Hence, the approximate score is:

Option: A

A. 62.5 points.

Answer=A

Let's write the an equation in slope intercept for for the line.

y-intercept=10

slope=rise/run=15/2=7.5

equation:

y=mx+b
y=7.5x+10

Solve for x=7

y=7.5(7)+10
y=52.5+10
y=62.5
