Answer: A = 235 cm²

Step-by-step explanation: The figure has not a regular shape, but we can divide it to other figures that are easier to calculate the area.

For example, we can divide this figure in 2:

1) A square of side 9;

2) A rectangle of sides 14 and 11;

The image below represents what it is described.

Area of quadrilateral is calculated as A = length x width

Since both rectangle and square are quadrilateral, area of each will be

[tex]A_{square}[/tex] = 9.9

[tex]A_{square}[/tex] = 81

[tex]A_{rectangle}[/tex] = 11.14

[tex]A_{rectangle}[/tex] = 154

The area of the shape is the sum of each part we calculated:

[tex]A_{total}[/tex] = 154 + 81

[tex]A_{total}[/tex] = 235

The area of the shape is 235 cm².

B because you add each time starting from 3

Step-by-step explanation:

Answer:

You probably know that the number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well.

Here's a little tip for you. Any number can be converted to fraction if you use 1 as the denominator:

56

1

So now that we've converted 56 into a fraction, to work out the answer, we put the fraction 7/8 side by side with our new fraction, 56/1 so that we can multiply those two fractions.

That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:

7 x 56

8 x 1

=  

392

8

In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.

You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 392 and 8 is 8.

We can now divide both the new numerator and the denominator by 8 to simplify this fraction down to its lowest terms.

392/8 = 49

8/8 = 1

When we put that together, we can see that our complete answer is:

49

1

The complete and simplified answer to the question what is 7/8 of 56 is:

49

Hopefully this tutorial has helped you to understand how to find the fraction of any whole number. You can now go give it a go with more numbers to practice your newfound fraction skills.

Step-by-step explanation:

convert 56 into a fraction (56/1) then multiply 7/8 × 56/1. it equals out to 392/8. then find the GCF of 392 and 8, which is 8. now divide boht the new numerator and denominator by 9 to simplify it to lowest terms. 49 is the answer

Answer: Cards in second box are cheaper.

Step-by-step explanation:

We are told that the first box has 150 cards for $12.55. Therefore, the cost of one card would be:

= $12.55 / 150

= $0.084.

The second box has 120 cards for $9.60. Therefore, the cost if one card would be:

= $9.60 / 120

= $0.08

Therefore, the cards in the second box are cheaper.

Answer:

1st line: linear

2nd line: linear

3rd line: 4

4th line: represents

Step-by-step explanation:

Arithmetic sequences increase by the same number each time. This means they are linear, as linear functions also increase by the same number each time.

So, the first and second lines have the answer of linear.

In the arithmetic sequence given, 4 is added to the previous number as it progresses. This represents a function.

So, the third line has the answer of 4, and the fourth line has the answer or represents.

Using arithmetic sequence concepts, it is found that the lines are:

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of the sequence is given by:

[tex]a_{n+1} = a_1 + (n-1)d[/tex]

Hence, an arithmetic sequence is also a linear function with rate of change d.

In this problem:

Hence, the lines are completed by:

Answer:

[tex]\displaystyle \int {\frac{1}{\sqrt{x} \sqrt{1-x} } } \, dx = 2arcsin(\sqrt{x}) + C[/tex]

General Formulas and Concepts:

Calculus

Step-by-step explanation:

Step 1: Define

[tex]\displaystyle \int\limits {\frac{1}{\sqrt{x} \sqrt{1-x} } } \, dx[/tex]

Step 2: Identify

Set up variables for u-substitution and integral trig.

[tex]\displaystyleu = \sqrt{x}\\a = 1\\du = \frac{1}{2\sqrt{x}}dx[/tex]

Step 3: integrate

We are given the expression:                                                                              

[tex]\int\limits {\frac{1}{\sqrt[]{x} }*\frac{1}{\sqrt[]{ 1-x^{2}}} } \, dx[/tex]

U-substitution:                                                                                                      

let u = [tex]x^{1/2}[/tex]             [So, x = u²]

[tex]\frac{du}{dx} = \frac{1}{2\sqrt[]{x}}[/tex]                 [differentiating both sides wrt x]

dx = du*2√(x)

dx = 2u(du)            [Since u = √x]

Finding the Integral:                                                                                              

Plugging these values in the given expression:

[tex]\int\limits {u^{-1}*(1-u^{2})^{-1/2} } \, 2\sqrt[]{x}*du[/tex]

[tex]\int\limits {\frac{1}{u}*\frac{1}{\sqrt[]{ 1-u^{2}}}*2u } \, du[/tex]

The 'u' in the numerator and denominator will cancel out

[tex]\int\limits {\frac{1}{\sqrt[]{ 1-u^{2}}}*2 } \, du[/tex]

Since 2 is a constant

[tex]2\int\limits {\frac{1}{\sqrt[]{ 1-u^{2}}} } \, du[/tex]

Using the property: [tex]\int\limits {\frac{1}{\sqrt[]{1-x^{2}} }} \, dx[/tex] = ArcSin(x) + C

2*ArcSin(u) + C

Since u = √x :

2*ArcSin(√x) + C
