Point O is the center of the square ABCD. Point E is the midpoint of line segment CD. The area of square ABCD is 24, what is the are of the quadrilateral BCEO? ​

Answer:

22.3923

Step-by-step explanation:

Calculated based on 2 given angles and 1 given side.

∠A = 180° - B - C = 1.309 rad = 5/12π = 75°

a = b·sin(A)/sin(B) = 22.3923

c = b·sin(C)/sin(B) = 23.18222

Answer:

this would be 90 because you would need to multiply to answer it

Step-by-step explanation:

Answer:

Step-by-step explanation:

A ' = (-2, -3)

B ' = (0, -3)

C ' = (-1, 1)

=======================================================

Explanation:

To apply an x axis reflection, we simply change the sign of the y coordinate from positive to negative, or vice versa. The x coordinate stays as is.

Algebraically, the reflection rule used can be written as

Applying this rule to the three given points will mean....

Point A = (-2, 3) becomes A ' = (-2, -3)

Point B = (0, 3) becomes B ' = (0, -3)

Point C = (-1, -1) becomes C ' = (-1, 1)

The diagram is provided below.

Side note: Any points on the x axis will stay where they are. That isn't the case here, but its for any future problem where it may come up. This only applies to x axis reflections.

Answer:

B. 0.067

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Number of arrangements:

The number of possible arrangements of n elements is given by:

[tex]A_{n} = n![/tex]

Desired outcomes

First red(10 - (5+2) = 3 possible)

Last red(2 possible).

Middle 8 arranged in any way.

So

[tex]D = 3*A_{8}*2 = 3*8!*2 = 241920[/tex]

Total outcomes:

Arrangements of 10 elements. So

[tex]T = A_{10} = 10! = 3628800[/tex]

What is the probability that the first and last blouse are both red?

[tex]p = \frac{D}{T} = \frac{241920}{3628800} = 0.067[/tex]

The correct answer is given by option B.

Answer:

750 miles

Step-by-step explanation:

Given that,

The rental costs 350 per week plus 20 cents per mile.

Becky can spend no more than $500.

Let he travel x miles. We can form an equation as follows :

350 + 0.2x = 500

0.2x = 500-350

0.2x = 150

x = 750 miles

Hence, she can travel 750 miles.

Answer:

Step-by-step explanation: The equation is s = 9.8 – 9.8e-0.88t and we need to find the speed if t or time = 2 so to solve this equation algebraically you would;

[tex]s = 9.8-9.8e-0.88(2)[/tex]

[tex]s = 9.8-9.8e-1.76[/tex]

[tex]s = 8.04-9.8e[/tex]

and after graphing it you would get

[tex]-18.5991619189[/tex]

which after rounding and using absolute value would be

[tex]s=18.6[/tex]

Answer:

C: maximum height=62.25 feet; time=3.85 seconds

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

[tex]f(x) = ax^{2} + bx + c[/tex]

It's vertex is the point [tex](x_{v}, y_{v})[/tex]

In which

[tex]x_{v} = -\frac{b}{2a}[/tex]

[tex]y_{v} = -\frac{\Delta}{4a}[/tex]

Where

[tex]\Delta = b^2-4ac[/tex]

If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

[tex]ax^{2} + bx + c, a\neq0[/tex].

This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:

[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]

[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]

[tex]\Delta = b^{2} - 4ac[/tex]

In this question:

The height of the ball, after t seconds, is given by the following equation:

[tex]h(t) = -16t^2 + 60t + 6[/tex]

Which is a quadratic equation with [tex]a = -16, b = 60, c = 6[/tex]

Maximum height:

Since a < 0, we can find the maximum value of the function. We have that:

[tex]\Delta = 60^{2} - 4(-16)(6) = 3984[/tex]

[tex]y_{v} = -\frac{3984}{4(-16)} = 62.25[/tex]

The maximum height is of 62.25 feet.

Seconds to reach the ground:

[tex]x_{1} = \frac{-60 + \sqrt{3984}}{2*(-16)} = -0.1[/tex]

[tex]x_{2} = \frac{-60 - \sqrt{3984}}{2*(-16)} = 3.85[/tex]

Since time is a positive measure, 3.85 seconds.

The correct answer is given by option C.

Answer: 4 miles

Step-by-step explanation:

The circumference of a circle can be calculated by using the formula:

= 2πr

where,

π = 22/7

r = radius = 7/11 miles

Therefore, circumference = 2πr

= 2 × 22/7 × 7/11

= 4 miles

Th circumference is 4 miles.

Answer:

X = 33.3 percent

Step-by-step explanation:

Answer:

a) The car will be worth $8000 after 2.9 years.

b) The car will be worth $6000 after 4.2 years.

c) The car will be worth $1000 after 12.7 years.

Step-by-step explanation:

The value of the car after t years is given by:

[tex]V(t) = 14651(0.81)^{t}[/tex]

According to the model, when will the car be worth V(t)?

We have to find t for the given value of V(t). So

[tex]V(t) = 14651(0.81)^{t}[/tex]

[tex](0.81)^t = \frac{V(t)}{14651}[/tex]

[tex]\log{(0.81)^{t}} = \log{(\frac{V(t)}{14651})}[/tex]

[tex]t\log{(0.81)} = \log{(\frac{V(t)}{14651})}[/tex]

[tex]t = \frac{\log{(\frac{V(t)}{14651})}}{\log{0.81}}[/tex]

(a) $8000

V(t) = 8000

[tex]t = \frac{\log{(\frac{8000}{14651})}}{\log{0.81}} = 2.9[/tex]

The car will be worth $8000 after 2.9 years.

(b) $6000

V(t) = 6000

[tex]t = \frac{\log{(\frac{6000}{14651})}}{\log{0.81}} = 4.2[/tex]

The car will be worth $6000 after 4.2 years.

(c) $1000

V(t) = 1000

[tex]t = \frac{\log{(\frac{1000}{14651})}}{\log{0.81}} = 12.7[/tex]

The car will be worth $1000 after 12.7 years.

Answer:

g(-2) = -5

Step-by-step explanation:

We are given the following function:

[tex]g(x) = \sqrt[3]{x - 123}[/tex]

Find g( - 2).

This means that we find g when [tex]x = -2[/tex]. So

[tex]g(-2) = \sqrt[3]{-2 - 123} = \sqrt[3]{-125} = \sqrt[3]{-5^3} = -5[/tex]

So

g(-2) = -5

Answer:

$86.8

Step-by-step explanation:

Given that,

Principal, P = $80

Rate of interest, R = 8.5%

We need to find the money he will have in 1 year. As the interest is not compounded, it must be simple interest. The simple interest can be calculated by the formula,

[tex]I=\dfrac{PRT}{100}\\\\I=\dfrac{80\times 8.5\times 1}{100}\\\\=\$ 6.8[/tex]

We know that,

Amount = Principal + interest

= $80 + $6.8

= $86.8

Hence, the amount will become $86.8.

Answer:

  BE = 266 2/3

  PE = 233 1/3

Step-by-step explanation:

Part A: The figure has 3 triangles, all similar. In order of shortest-to-longest side lengths, they are ...

  ΔBPE ~ ΔBCG ~ ΔGRE

__

Part B: They can be declared similar by the AA postulate. For BPE and BCG, the angles at B are vertical angles, so are congruent. The angles at C and G are alternate interior angles, so are congruent.

For triangles BPE and GRE, angle E is congruent to itself, The angles at R and P are corresponding angles, so are congruent.

(Remember, GRPC is a parallelogram, so any line in the figure is a transversal crossing parallel lines.)

__

Part C:

From parts A and B, we know ΔBPE ~ ΔBCG. Corresponding sides are proportional:

  BP/BC = BE/BG = PE/CG

  200/300 = BE/400 = PE/350

  BE = (400)(2/3) = 266 2/3

  PE = (350)(2/3) = 233 1/3

Step-by-step explanation:

Answer:

i2 - 9

-85

Step-by-step explanation:

Conjugate of an expression is gotten by simply changing the sign to the opposite sign. For example, the conjugate of 5 is -5, the conjugate of x+2 is x-2. Given the complex value 2i+9, the conjugate will be -85

Taking their product

(2i+9)(2i-9)

Expand

2i(2i)-9(2i)+9(2i)+9(-9)

=  4i²-18-+18i-81

= 4i² - 81

Since i² = -1

= 4(-1) - 81

= -4-81

= -85

Hence the product will give -85

Answer:

y = 3cos(81x)

Step-by-step explanation:

Hello!

Here is the foundational equation to find sine and cosine:

y = A sin(B(x + C)) + D

Any cosine function can be written as a sine function. y = A sin(Bx) and y = A cos(Bx). The number, A, in front of sine or cosine changes the height of the graph. The value A (in front of sin or cos) affects the amplitude (height). B is the period by which the width of the wavelengths are measrured. C is known as the phase shift, which is positive to the left on graph. D is the vertical shift of function.

The amplitude changes the heaight of the cosine function by 3 units. The period is indicated as 81 and , but usually we must first use the equation that is the usual given: period = [tex]\frac{2\pi }{|B|}[/tex] . B must always have an absolute sign to have a psotive value. In this case, the period was given to us.

So, the final equation looks like this:

y = 3cos(81x)

Hope this helps!
