Answer:

The area of the circle is 2.41 in^2

Step-by-step explanation:

You are given the diameter, 1 3/4. This is a mixed fraction, so let's convert that into decimal.

1 3/4 = 7/4

7/4 = 1.74

Now, let's use the area of circle formula.

A = 1/4πd^2

A = 1/4 * π * 1.75^2

A ≈ 2.40528

Let's round the area to the nearest hundredth.

2.40528 = 2.41

Step-by-step explanation:

7x + 6 = 4x + 9

3x = 3

x = 1

Answer:

[tex] (gof)(x) = g(f(x)) \\ = (3x)^{2} - 4(3x) - 6 \\ = 9 {x}^{2} - 12x - 6 \\ \\ (gof)(4) = g(f(4)) \\ = 9( {4}^{2} ) - 12(4) - 6 \\ = 9(16) - 48 - 6 \\ = 144 - 48 - 6 \\ = 90[/tex]

Given that,

We have to calculate the area of the square.

⠀⠀⠀⠀⠀★ Area of square = (Side)² ★

[tex] \dashrightarrow \quad \rm { Area = [10 - 3x(-2)]^2 \; cm^2} \\ [/tex]

[tex] \dashrightarrow \quad \rm { Area = [10 + 6x]^2 \; cm^2} \\ [/tex]

[tex] \dashrightarrow \quad \rm { Area = (10)^2 + (6x)^2 + 2(10 \times 6x) \; cm^2} \\ [/tex]

[tex] \dashrightarrow \quad \rm { Area = 100 + 36x^2 + 2(60x) \; cm^2} \\ [/tex]

[tex] \dashrightarrow \quad \underline{\boxed{\bf { Area = 100 + 36x^2 + 120x \; cm^2}}} \\ [/tex]

[tex]\rule{200}2[/tex]

Answer:

36x^2 + 120x + 100 cm^2.

Step-by-step explanation:

[10 - 3x (-2)]

= 10 + 6x

The area = (10 + 6x)^2

= (10 + 6x)(10 + 6x)

= 10*10 + 10*6x + 10*6x + 6x*6x

= 100 + 60x + 60x + 36x^2

= 100 + 120x + 36x^2.

Answer:

It's A

Step-by-step explanation:

Using process of elimination B is wrong because even though you get 37 and 36 it multiplies them because of a lack of addition symbol. C is also wrong because it would turn out to be 12 x 13 which is larger than C so that's not it. in D 3x4 is 12 but it's added to 9 not multiplied so that's wrong which leaves you with A which is 9(3 + 4) = 63 and 27 + 36 = 63

Answer:

Yes she is correct

Step-by-step explanation:

Suppose before we add and additional element x to a set A the number of subsets are n.

Now we can think of the subsets of the new set A union x as the subsets containing x and the subsets that are not containing x.

The subsets that are not containing x are exactly the former n subsets of A and the subsetes that are containing x is obtained by appending x to each of the n subsets. So we get another n subsets.

Therefore there are n + n =2n subsets which is double of the original subsets.

Therefore, there are n + n = 2n subsets which are doubled of the original subset.

Sets are the collection of well-defined elements. A set is represented by a capital letter symbol and the number of elements in the finite set is shown as curly bracket {..}.

A ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given

Every time they add an element to a set, the number of subsets doubles.

Let the number of sets be n

But every time they add an element to a set, the number of subsets doubles.

Then according to the condition,

n + n = 2n

Therefore, there are n + n = 2n subsets which are doubled of the original subset.

Step-by-step explanation:

Perimeter means add up all the sides

The top is 4+b, and b is 10, so the top and bottom are 14 each

The side is a which is 6 so

p=bottom+top+left side+right side

[tex]\sqrt{18}[/tex] = [tex]3\sqrt{2}[/tex] = 4.24264...

Mixed fraction:

Answer:

  d. √16, 4.23_23, √18, 4 2/3

Step-by-step explanation:

There are a couple of different ways to compare these numbers. Maybe one of the most straightforward is to find the decimal equivalent, rounded to hundredths.

  4.23_23 ≈ 4.23

  4 2/3 ≈ 4.67

  √18 ≈ 4.24

  √16 = 4.00

These can be sorted least-to-greatest by putting the first number (4.23) between the last two (4.00, 4.24) and reading the new list last-to-first.

  4.00, 4.23, 4.24, 4.67   ⇔   √16, 4.23..., √18, 4 2/3

_____

Additional comment

Another way to work this problem is to square the numbers not under a radical. 4.23...² ≈ 17.91 and (4 2/3)² ≈ 21.78. The ordering of the squares is the same as the ordering of their square roots.

  16 < 17.91 < 18 < 21.78   ⇔   √16 < 4.23... < √18 < 4 2/3

I hope I helped you^_^

Step-by-step explanation:

Solution

According to remainder theorem, when f(x) is divided by (x+2), Remainder =f(−2)

f(x)=5x3+2x2−6x+12

f(−2)=5(−2)3+2(−2)2−6(−2)+12

=5×−8+2×4+12+12

=−40+32=−8

∴ Remainder=−8

Answer:

30.5 meters

10.5 meters

Step-by-step explanation:

x = length

y = width

x = y + 20

2x + 2y = 82 (the perimeter of a rectangle)

using the first equation as substitute in the second equation we get

2×(y + 20) + 2y = 82

2y + 40 + 2y = 82

4y = 42

y = 42/4 = 21/2 = 10.5 meters

x = y + 20 = 21/2 + 20 = 21/2 + 40/2 = 61/2 = 30.5 meters

Using exponential functions, it is found that the correct option is given by:  [15, ∞)

-------------------------

The exponential function given in this exercise is:

[tex]M(t) = 25000(\frac{4}{5})^t[/tex]

-------------------------

The domain that contains all the years the car's value is less than $1,000 is composed by the values of t for which:

[tex]M(t) < 1000[/tex]

Thus, we have to solve the exponential inequality.

[tex]M(t) < 1000[/tex]

[tex]25000(\frac{4}{5})^t < 1000[/tex]

[tex](\frac{4}{5})^t < \frac{1}{25}[/tex]

[tex]\log{(\frac{4}{5})^t} < \log{\frac{1}{25}}[/tex]

[tex]-0.0969t < -1.39794[/tex]

[tex]0.0969t > 1.39794[/tex]

[tex]t > \frac{1.39794}{0.0969}[/tex]

[tex]t > 14.43[/tex]
