rx-axis o T- 6,1 (x,y)

Step-by-step explanation:

We can see in the diagram that distances of  and  from the x-axis are equal with the distances of  and  from the x-axis respectively.

That means,  is first reflected about the x-axis to form

Now,  and  are located at 6 units left and 1 unit up from  and .

Answer:

[tex]x=53[/tex]

Step-by-step explanation:

step 1

Find the measure of arc DF

we know that

The inscribed angle measures half that of the arc comprising

so

[tex]m<OEF=\frac{1}{2}(arc\ DF)[/tex]

we have

[tex]m<OEF=32\°[/tex]

substitute

[tex]32\°=\frac{1}{2}(arc\ DF)[/tex]

[tex]arc\ DF=64\°[/tex]

step 2

Find the measure of x

we know that

[tex]arc\ DF+arc\ EF=180\°[/tex] ---> is half the circle

we have

[tex]arc\ DF=64\°[/tex]

[tex]arc\ EF=(2x+10)\°[/tex]

substitute

[tex]64\°+(2x+10)\°=180\°[/tex]

[tex]2x\°=180\°-74\°[/tex]

[tex]2x\°=106\°[/tex]

[tex]x=53[/tex]

The value of x for the angles of the inscribed circle is gotten as; x = 53°

Let us first find the angle subtended by the arc DF

From inscribed angle theorem, we know that the measure of an inscribed angle is half the measure of the intercepted arc. Thus;

m∠EOF = ¹/₂(arc DF)

Thus;

¹/₂(arc DF) = 32°

arc DF = 64°

From half circle theorem, we can say that;

arc DF + arc EF = 180°

Thus;

64 + 2x + 10 = 180

2x = 180 - 74

2x = 106

x = 53°

P(x < 5) = 0.70

Step-by-step explanation:

Note:  The area under a probability "curve" must be = to 1.

Finding the sub-area representing x < 5 immediately yields the desired probability.

Draw a dashed, vertical line through x = 5.  The resulting area, on the left, is a trapezoid.  The area of a trapezoid is equal to:

 (average length)·(width, which here is:

Answer:

201 ft²

Step-by-step explanation:

Area of a circle is given by the formula

πr²

Thus area

= 3.142 × 8 × 8

=  201.088

= 201 ft²

Answer:

Option C

201 feet²

Step-by-step explanation:

Given in the question,

diameter of the circular graph = 16 feet

Formula to calculate the area of garden

where π is constant = 3.14

           r is the radius

To find the radius

16/2

8 feet

Plug in values to calculate area

(3.14) 8²

200.96 feet²

Area of the circular garden having 16 feet diameter is 201 (approximate)

The area of the trapezoidal courtyard is 114 square meters.

To find the area of a trapezoid, you can use the formula:

[tex]\[ \text{Area} = \frac{1}{2} \times (\text{sum of the bases}) \times \text{height} \][/tex]

Given:

- Base 1 (b1) = 8 meters

- Base 2 (b2) = 11 meters

- Height (h) = 12 meters

Plugging these values into the formula:

[tex]\[ \text{Area} = \frac{1}{2} \times (8 + 11) \times 12 \][/tex]

[tex]\[ \text{Area} = \frac{1}{2} \times 19 \times 12 \][/tex]

[tex]\[ \text{Area} = \frac{1}{2} \times 228 \][/tex]

[tex]\[ \text{Area} = 114 \][/tex]

So, the area of the courtyard is 114 square meters.

Answer:

A. (2x-3)/2

Step-by-step explanation:

Performing the long division indicated by the perimeter expression, you find ...

perimeter = (2x -3) + (10x +6)/(x^2 +2x)

Comparing this to the formula for the perimeter ...

perimeter = 2W +2L

where L is said to be of the form (ax +b)/(x^2 +2x)

we can match terms in the perimeter expression to see that ...

2W = 2x -3

2L = (10x +6)/(x^2 +2x)

The problem doesn't ask for it, but we can see that (a, b) = (5, 3). We can also see that ...

W = (2x -3)/2 . . . . . . . matches choice A

Answer:

2650

Step-by-step explanation:

Given: 2648

Two significant figures means we need to round off to the nearest tens place.

In 2648, the tens place is 4

To round off the tens place, we need to look for the next digit that is right to tens place, which is 8

8 is greater than 5, so we need to add 1 with tens place (4 +1 = 5)

Therefore, it is 2650

Hope this will helpful.

Thank you.

2648 to two significant figures is 2700

The significant figures of a number are digits that carry meaning contributing to its measurement resolution. This includes all digits except all leading zeros

There are three rules determining how many significant figures are in a number:

For addition and subtraction use the following rules:

For multiplication and division use the following rule:

The given number is 2648

2648 can be written in two significant figures as 2700

2648 has four significant figures such as 2,6,4,8.

The second digit in the given number 2648 is '6'

Because the number 6 is greater than 5, therefore it can be rounded as '7'

Therefore, the number 2648 with four significant figures can be written as 2700 in two significant figures.

So 2700 has only two significant figures: 2 and 7.

Answer: OPTION A

Step-by-step explanation:

Apply the Quadratic formula, which is:

[tex]x=\frac{-b\±\sqrt{b^2-4ac}}{2a}[/tex]

In this case:

[tex]a=1\\b=-6\\c=58[/tex]

Then, you must susbtitute these values into the quadratic formula, as shown below:

[tex]x=\frac{-(-6)\±\sqrt{(-6)^2-4(1)(58)}}{2*1}[/tex]

[tex]x=\frac{6\±\sqrt{-196}}{2}[/tex]

Keep on mind that [tex]i=\sqrt{-1}[/tex], then you can rewrite it as following:

[tex]x=\frac{6\±14i}{2}\\\\\\x=\frac{2(3\±7i)}{2}\\\\x=3\±7i\\\\x_1=3+7i\\x_2=3-7i[/tex]

Answer:

A. {[tex]3+7i,3-7i[/tex]}

Step-by-step explanation:

The given equation  is  [tex]x^2-6x+58=0[/tex]

Use the quadratic formula with a=1,b=-6 and c=58

Recall the quadratic formula;

[tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]

We substitute the given values to get;

[tex]x=\frac{--6\pm \sqrt{(-6)^2-4(1)(58)} }{2(1)}[/tex]

[tex]x=\frac{6\pm \sqrt{36-232} }{2}[/tex]

[tex]x=\frac{6\pm \sqrt{-196} }{2}[/tex]

Recall that;

[tex]\sqrt{-1}=i[/tex]

[tex]x=\frac{6\pm 14i}{2}[/tex]

[tex]x=3\pm 7i[/tex]

[tex]x=3+7i[/tex] or [tex]x=3-7i[/tex]

Answer:

Step-by-step explanation:

For this problem, point slope form would be the easiest.

Point Slope Form- y-y1 = m(x-x1)

In this case, y1 is 3, x1 is 5, and m would be the slope which is -4.

y-3=-4(x-5)

This is how to write an equation for the problem.

Answer:

[tex]\large{\boxed{y-3=-4(x-5)-\text{point-slope form}}\\\boxed{y=-4x+23}}[/tex]

Step-by-step explanation:

The equation of a line in point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

m - slope

(x₁, y₁) - point

We have the slope m = -4 and the point (5, 3). Substitute:

[tex]y-3=-4(x-5)[/tex]       use distributive property

[tex]y-3=-4x+(-4)(-5)[/tex]

[tex]y-3=-4x+20[/tex]       add 3 to both sides

[tex]y=-4x+23[/tex]
