exis [7]3 years ago
6 0

Answer:

C

Step-by-step explanation:

The area of the sector and the whole circle are proportional to the central angles.

a / A = x / 360°

a = (x / 360°) A

So the answer is C.

Answer urgently needed pls
Roman55 [17]

Given that the integral is given as \int_{0}^{12} f(t) dt, Hence, we are required to find the area under the graph where t is between 0 and 12. The correct answer is 2 (Option A) See the explanation below.

<h3>What is an integral?</h3>

An integral is a function of which a given function is the derivative, that is, when differentiated, it returns that function, and it can express the area under the curve of a graph of the function.

Hence the areas under the graph for the above function are given as:

12 + 6 + 2 + (-2) + (-16)

= 20-18

= 2

Notice that the following figures were arrived at by dividing the areas under the graph into common geometric shapes and deriving their area.

For example, the first three positive values were derived by dividing the positive part of the graph into two triangles and a rectangle.

The length of the rectangle is 6 while its height is 2

Area of a rectangle is L x W

= 6 * 2

= 12

It is to be noted that the areas under the curve are negative hence the negative results. See the attached image.

How many solutions does the system have?<br> 3x + y = 8<br> 2 + 2y = 8
REY [17]

Answer:

x=2,y=2

Step-by-step explanation:

This question is a simultaneous equation

So let's solve

3x+y=8...(1)

2x+2y=8....(2)

Multiply (1) by 2

6x+2y=16...(3)

Substrate (2) From (3)

4x=8

Let's make x the subject of formula by dividing both sides by 4

x=2

So let's substitute the value of x into (1)

3x+y=8

3(2)+y=8

6+y=8

y=8-6

y=2

Therefore x is 2,y is 2

Help would be nice thank you!
Helen [10]

Answer:

Option B

Step-by-step explanation:

Given equation gives the information about the temperature in Vancouver over a period of 4 hours.

y = -2x + 43

Here 43 represents the initial temperature and (-2) represents the temperature fall in every one hour.

x = duration or time

Therefore, equation states that initial temperature when measured was 43 °F and it is dropping by 2 degrees per hour.

Option B is the answer.
