Answer:

6 units left and 4 up (if figure K translated)
6 units right and 4 units down (if figure J translated)

Step-by-step explanation:

It is not clear which of the figures is translated.

Assume it is figure K.

Use one of the points and compare the corresponding point.

If you take bottom-left point, then the difference is coordinates is:

-7 - (-1) = -6, this is translation left by 6 units (or right if the figure J is translated)
2 - (-2) = 4, this is translation up by 4 units (or down if the figure J is translated)

So the answer is

6 units left and 4 up or, (figure K translated)
6 units right and 4 units down (figure J translated)

Exploring the graph of y equals cosine Theta

irga5000 [103]

Answer: see below

Step-by-step explanation:

The coordinates on the Unit Circle are (cos, sin). Since we are focused on cosine, we only need to focus on the left side of the coordinate. The cosine value (left side) will be the y-value of the function y = cos x

Use the quadrangles (angles on the axes) to represent the x-values of the function y = cos x.

Quadrangles are: 0°, 90°, 180°, 270°, 360° (360° = 0°)

Together, the coordinates will be as follow:

$\boxed{\begin{array}{c||c|c||c}\underline{(cos,sin)}&\underline{x=angle}&\underline{y=cosx}&\underline{\quad (x,y)\quad}\\(1,0)&0^o&1&(0^o,1)\\(0,1)&90^o&0&(90^o,0)\\(-1,0)&180^o&-1&(180^o,-1)\\(0,-1)&270^o&0&(270^o,0)\\(1,0)&360^o&1&(360^o,1)\end{array}}$

Fofino [41]

Answer:

It will cost is $828.75.

Step-by-step explanation:

Given:

Davis is putting tile in his rectangular kitchen. His kitchen is 13 feet long, and 17 feet wide. The tile davis is installing is $3.75 per square foot.

Now, to find the total cost.

Davis is putting tile in his rectangular kitchen.

Length = 13 feet.

Width = 17 feet.

So, to get the area of kitchen:

Area = length × width

Area = 13 × 17

Area = 221 square foot.

As, the unit rate is given.

Cost per square foot = $3.75.

Now, to get the total cost by using unitary method:

If cost of 1 square foot = $3.75.

So, the cost of 221 square foot = $3.75 × 221

= $828.75.

Therefore, it will cost $828.75.

Select the correct answer from the drop-down menu. A whole number is 6 more than 2 times another number. The sum of the two numb

olya-2409 [2.1K]

Answer:

$x = \{13,14\}$

Step-by-step explanation:

Given

$x + 2x + 6 < 50$

Required

True values of x

We have:

$x + 2x + 6 < 50\\$

$3x + 6 < 50$

Collect like terms

$3x < 50-6$

$3x < 44$

Divide both sides by 3

$x < 44/3$

$x < 14.67$

This means that x has a value lesser than 14.67.

Hence, the valid values are:

$x = \{13,14\}$

It takes the earth 24 h to complete a full rotation. It takes Mercury approximately 58 days, 15 h, and 30 min to complete a full

Nastasia [14]

It takes Mercury approximately 58 days, 15 h, and 30 min to complete a full rotation..

We are going to write the time not in days, hours and minutes, but only hours.

This means that we have to write 58 days as hours and 30 minutes as hours.

1 day is 24 hours, so 58 days are

58*24=(50+8)*(20+4)=50*20+50*4+8*20+8*4=1,000+200+160+32

=1,200+192=1,392 (hours)

60 minutes are 1 hour, so 30 minutes are 0.5 hours.

Thus

58 days, 15 h, and 30 min are (1,392+15+0.5) hours = 1,407.5 hours

Answer: 1,407.5 hours
