Answer:

< - 5, 3.5 >

Step-by-step explanation:

A single translation is required to map A onto B

Consider the point (5, 3 ) on A and the corresponding point (0, 6.5) on B

the translation is < 0 - 5, 6.5 - 3 > = < - 5, 3.5 >

2 and 2/3 of what number is 13

andreev551 [17]

Step-by-step explanation:

Can you please write the question correctly

if you want to calculate two and two third the number ...just multiply 8/3 ×13 but if it equation 2 2/3x=13

8/3x=13 so x= 13÷(8/3)=13×(3/8)= 39/8=4.875

There are approximately 40,000 people that live in a city. A sample of 20,000 people from that city are asked and 8,000 live in

Archy [21]

Answer:

16,000 people

Step-by-step explanation:

Let's write a ratio

8,000:20,000

Let's write another ratio

x:40,000

We can write a percent proportion.

$\frac{8,000}{20,000} =\frac{x}{40,000}$

We can see that the relationship between the denominators is multiplied by 2 so that means the relationship between 8,000 and x is x is 2 times greater than 8,000

Let me know if you have any questions.

Plz I need Answer For It Will give Good Rating

avanturin [10]

Answer:

Step-by-step explanation:

1. Find where the line crosses on the y-axis

2. Find two corresponding points on the graph and do the rise/run method, which in this problem is 4/1 or 4( 4÷1= 4)

- When the line is like this / you rise from up and run to the right(positive), but when it is like this \ you rise from down and run to left (negative)

Ps: You should have taken the picture at a different angle 'cause I can see what you looks like and see part of your room.

Hope I was helpful =)

Verify cot x sec^4x=cotx +2tanx +tan^3x

Tanzania [10]

Answer:

See explanation

Step-by-step explanation:

We want to verify that:

$\cot(x) \: { \sec}^{4} x = \cot(x) + 2 \tan(x) + { \tan}^{3} x$

Verifying from left, we have

$\cot(x) \: { \sec}^{4} x = \cot(x) \: ( 1 + { \tan}^{2} x )^{2}$

Expand the perfect square in the right:

$\cot(x) \: { \sec}^{4} x = \cot(x) \: ( 1 + { 2\tan}^{2} x + { \tan}^{4} x)$

We expand to get:

$\cot(x) \: { \sec}^{4} x = \cot(x) \: + \cot(x){ 2\tan}^{2} x +\cot(x) { \tan}^{4} x$

We simplify to get:

$\cot(x) \: { \sec}^{4} x = \cot(x) \: + 2 \frac{ \cos(x) }{\sin(x) ) } \times \frac{{ \sin}^{2} x}{{ \cos}^{2} x} +\frac{ \cos(x) }{\sin(x) ) } \times \frac{{ \sin}^{4} x}{{ \cos}^{4} x}$
