Answer:

The length of the arc is: [tex]\pi\,\,cm\approx\,3.14\,\,cm[/tex]

Step-by-step explanation:

Notice that a circle of diameter 2 cm has radius 1 cm (half of the diameter).

Also notice that the length of the full circle (which corresponds to a [tex]360^o[/tex] arc, is the circumference length given by the known formula [tex]2\,\pi \, R[/tex], so the arc subtended by half such angle (that is a [tex]180^o[/tex] angle would be: [tex]\frac{2\,\pi \, R}{2} = \pi \, R[/tex]

Therefore with this info we get that:

the length of this 180° arc for a radius of 1 cm is = [tex]\pi \, R= \pi\,1\,cm=\pi\,\,cm\approx\,3.14\,\,cm[/tex]

Answer:

The distance between to 2 point is 15 units.

Step-by-step explanation:

You have to apply distance formula using coordinates :

[tex]distance = \sqrt{ {(x2 - x1)}^{2} + {y2 - y1)}^{2} } [/tex]

Let (x1,y1) be (-8,6),

Let (x2,y2) be (1,-6),

[tex]distance = \sqrt{ {(1 + ( - 8))}^{2} + { (- 6 - 6)}^{2} } [/tex]

[tex]distance = \sqrt{81 + 144} [/tex]

[tex]distance = \sqrt{225} [/tex]

[tex]distance = 15 \: units[/tex]

Answer:

x ≤5

Step-by-step explanation:

There is a closed circle at 5 so that means equals

The line goes to the left so that means less than

x ≤5

Answer:

C

Step-by-step explanation:

Since the circle is close, we can assume it has to be C or D. But if we want to find out, we think of x as let's say 4. 4 is less than 5, and numbers 5 or less is x, so the answer would be C. (hope it helps)

Answer:

62 centimeters

Step-by-step explanation:

2*3*2+3*5*2+2*5*2=62

[tex]4-3x=22[/tex]

[tex]-3x=22-4[/tex]

[tex]-3x=18[/tex]

[tex]x=18/-3[/tex]

[tex]x=-6[/tex]

[tex]2( x + 4) = 3 + 8[/tex]

[tex]2x+8=11[/tex]

[tex]2x=11-8[/tex]

[tex]x=3/2[/tex]

[tex]2/3x + 5/6 = 1[/tex]

[tex]2/3x=1-5/6[/tex]

[tex]2/3x=1/6[/tex]

[tex]12x=3[/tex]

[tex]x=3/12[/tex]

[tex]x=1/4[/tex]

Total measure of triangle=180

Therefore, 60+2x+x=180

3x=180-60

x=120/3

x=40

2x= 40×2=80

B=40

A=80

The value of angle A is 40 degree.

The value of angle B is 80 degree.

Answer: Linear; y=-x - 1

Step-by-step explanation: The slope is negative since it’s decreasing. So it’s not the first equation. It’s not a quadratic equation because there is no forming U shape for this data. It’s not a exponential function because the slope is not 3 and a exponential function is in the form y=a(b)^x.

Step-by-step explanation:

2/5

If Kostya randomly chooses a number from 1 to 10 then 2/5 is the probability Kostya chooses a number less than 5.

It is a branch of mathematics that deals with the occurrence of a random event.

Given that Kostya randomly chooses a number from 1 to 10.

We have to find the  probability he chooses a number less than 5

There are four numbers that are less than 5 .

The numbers less than 5 are 1, 2, 3, 4.

The probability that Kostya randomly chooses one of these numbers is 4/10,

Divide numerator and denominator by 2

We get 2/5

Hence, if Kostya randomly chooses a number from 1 to 10 then 2/5 is the probability he chooses a number less than 5.

Step-by-step explanation:

The solution of the expression √14 × √10​ is 2√35. The correct option is D.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given expression is √14 × √10​. The expression will be solved as,

E = √14 × √10​

E = 2 √( 7 x 5 )

E = 2√35

Therefore, the solution of the expression √14 × √10​ is 2√35. The correct option is D.

Step-by-step explanation:

A P E X

All options could change a taxpayer's adjusted gross income when filing a federal income tax return.

Options A, B, C, and D are the correct answers.

Taxpayer-adjusted gross income (AGI) is a person's gross income (all income from various sources such as wages, self-employment, interest, dividends, and capital gains) minus certain deductions (such as contributions to a traditional IRA, alimony payments, and student loan interest).

We have,

- Medical and dental expenses are deductible if they exceed a certain percentage of the taxpayer's adjusted gross income.

- Contributions to an IRA may be deductible, which would lower the taxpayer's adjusted gross income.

- Casualty and theft losses may be deductible if they exceed a certain percentage of the taxpayer's adjusted gross income.

- Charitable contributions made are deductible if the taxpayer itemizes deductions, which would lower the taxpayer's adjusted gross income.

Thus,

All of the above could change a taxpayer's adjusted gross income when filing a federal income tax return.

Answer:

I=V/R

Step-by-step explanation:

In this equation, we see that there are no numerical values so we can't exactly solve for the exact number. Because of this, all you do Is isolate the variable "I" by itself. To do this, divide R on both sides. This way, you isolate I and on the other side you get V/R that cannot be further simplified.

Answer:

I=V/R

Step-by-step explanation:

V=IR

Divide both sides by R to isolate I

V/R=I

Answer: 2/3x

Step-by-step explanation:

First, you need to simplify your original line to point slope formula. Dividing the whole thing by 2 to get y by itself leaves you with

y = 3/2x - 1/2

Any perpendicular line has the opposite slope to the line it is perpendicular to, so you flip the slope to get 2/3x

Answer:

Each x value occurs only once

Step-by-step explanation:

In order for something to be classified as a function, it must pass the vertical line test, meaning a vertical line should never hit 2 points on the function, meaning each x value appears once. Y values can occur as many times, as long as each x value occurs once, it is a function. In this case, a y value appears 2 times, but each x value only does so once.

Answer:

The inequality can be written as:

45x + 1240 ≥ 6000

Step-by-step explanation:

Total number of members = 45

If one person donates the sum of = $x

Then the total amount raised by 45 people becomes = 45x

Minimum amount of money required to compete in the championship = $6000.

Money which they already have = $1240

So, Amount of money they have to raise = $6000 - $1240

We can show inequality as:

45x ≥ 6000 - 1240

Which show that the total amount raised by 45 people (45x) should be equal or greater than the amount of money they have to raise ($6000 - $1240)

Rearrange the equation;

45x + 1240 ≥ 6000

Answer:

80 feet

Step-by-step explanation:

length of pool = 22    ,  width of pool = 18

feet required for fencing the pool = 2 (l +b)

= 2 ( 22+18)

=2*40

=80feet

Answer:

Step-by-step explanation:

The pool is a rectangle as length and breadth are different.

Since they are asking about fencing you need to find the perimeter.

Length=22feet

Breadth=18feet

Perimeter of a rectangle = 2(l+b)

= 2 × 22 + 2×18

=44+36

=80 feet

Answer:

Step-by-step explanation:

a² + b² + c² = 39

ab + bc + ca = 21

(a + b + c)² = a² + b² +c² + 2[ab + bc +ca]

(a + b + c)² = 39 + 2*21

                 = 39 + 42

(a+ b + c)² = 81

a +b + c = √81 = √9*9

a + b + c = 9
