You should find the area under the curve. Which will give you multiple shapes. That are 3 triangles and one rectangle. Then use the Rule of the area of the triangle which is 1/2 × base × height then lastly. When you find the area for each shape you then find the sum of all the distance to give you the full area under the curve.

Suppose you are asked to find the area of a rectangle that is 2.1-cm wide by 5.6-cm long. Your calculator answer would be 11.76

yulyashka [42]

Answer:

$12 cm^2$

Step-by-step explanation:

We are given that

Width of rectangle=b=2.1 cm

Length of rectangle=l=5.6 cm

We have to find the area of rectangle.

We know that

Area of rectangle= $l\times b$

Using the formula

Area of rectangle = $2.1\times 5.6$

Area of rectangle= $11.76\approx 12 cm^2$

Hence, the area of rectangle= $12 cm^2$

Answer: 6 teams

Step by step:

3 people=1 group

3+3=6

6 people taken out of 18

2 groups already

3+6=9

9 out of 18 people taken

3 groups made

9+3=12

12 out of 18 people taken

4 groups made

12+3=15

15 out of 18 people taken

5 groups made

15+3=18

18 out of 18 people taken

Answer: 6 groups made

Short step by step:

18 divided by 3 equals 6

Or

3 times 6 equals 18

I really hope that made sense

If 1 - cosA= 1/2 show that tan²A + 4sin²A = 6

pav-90 [236]

$\text{Given that,}\\\\1-\cos A = \dfrac 12\implies \cos A = 1-\dfrac 12 = \dfrac 12\\\\\text{L.H.S}\\\\=\tan^2 A + 4 \sin^2 A\\\\=\dfrac{\sin^2 A}{\cos^2 A}+4(1-\cos^2 A)\\\\\\=\dfrac{1-\cos^2 A}{\cos^2 A} +4-4\cos^2 A\\\\\\=\dfrac{1-\left( \dfrac 12 \right)^2 }{\left(\dfrac 12 \right)^2 } +4 -4 \left( \dfrac 12 \right)^2\\\\\\=\dfrac{1- \dfrac 14}{\dfrac 14}+4-4\cdot \dfrac 14\\\\\\=\dfrac{\tfrac 34}{\tfrac 14}+4-1\\\\\\=\dfrac 34 \cdot 4 +3\\\\=3+3\\\\=6\\\\=\text{R.H.S}$

Identify which of these designs is most appropriate for the given experiment: completely randomized design, randomized blockd

sasho [114]

Answer:

Matched pairs design

Step-by-step explanation:

Looking at the options;

-It's not a completely randomized design because a randomized design will assign all individuals to a group which in this case it doesn't.

- It's not a randomized block design because randomized block design will group the subjects in question into 2 or more blocks which have a common characteristic and will then randomly assign subjects in each of the blocks.

-It's a matched pair because every individual/subject undergoes measurements both before and after being treated with the drugs.

Thus, the correct option is matched pairs design.

Seven more than the product of a number and 2 is equal to 9

Lina20 [59]

Answer:2x+7=9

Step-by-step explanation:

When it says seven more you add that to the end of the equation and set it equal to 9 then product of a number (x) and 2 so it would be 2x. Hope this helps!
