Tell whether the relation is a function. Explain your reasoning
{(-1, 7), (9, 4), (3, -2), (5, 3), (9, 1)}

Answers

Answer 1

Answer:

no, since the numbers are mixed up both negative and positive

Answer 2

Answer:

relation is a function

Step-by-step explanation:

For the relation to be a function each value of x in the domain must map to exactly one unique value of y in the range.

This is the case here so the relation is a function

y = 4x + 7

X-intercept: ( __ , __ )
Y-intercept: ( __ , __ )

Answers

Answer:

y intercept is (0,7) & x is (7/4,0)

Step-by-step explanation:

you put 0 for y or x and solve to get the intercept. for y int, you put 0 where the x is. for x int, put 0 at y.

y intercept is (0,7).

y = 4(0) + 7

y = 0 + 7

y = 7

x intercept is (7/4,0)

0 = 4x + 7

7 = 4x

7/4 = 4x/4

7/4 = x


Find the value of r.

Note: Write your answer as a decimal.

Answers

Answer:

[tex]\huge\boxed{\sf r = 10.5}[/tex]

Step-by-step explanation:

Since it is a right-angled triangle, it has base, perpendicular and hypotenuse.

Base = r

Perpendicular = 14

Hypotenuse = r + 7

Using Pythagoras theorem:

[tex](Hypotenuse)^2 = (Base)^2+(Perp)^2[/tex]

Put the values

(r + 7)² = (r)² + (14)²

Using formula a² + 2ab + b² = (a + b)²

r² + 14r + 49 = r² + 196

Subtract r² to both sides

14r + 49 = 196

Subtract 49 to both sides

14r = 196 - 49

14r = 147

Divide 14 to both sides

r = 147 / 14

r = 10.5

If \cos\theta = \frac{2}{\sqrt{14}}cosθ= 14 ​ 2 ​ and angle \thetaθ is in Quadrant I, what is the exact value of \tan 2\thetatan2θ in simplest radical form?

Answers

θ is in quadrant I, so cos(θ) and sin(θ) and hence tan(θ) are all positive.

Recall that

sec²(θ) = 1 + tan²(θ)

We have

cos(θ) = 2/√14   ⇒   sec(θ) = √14/2 = √(7/2)

Then

tan(θ) = +√(sec²(θ) - 1) = √(5/2)

Also recall the identities

sin(x + y) = sin(x) cos(y) + cos(x) sin(y)

cos(x + y) = cos(x) cos(y) - sin(x) sin(y)

from which we get

tan(x + y) = (sin(x) cos(y) + cos(x) sin(y)) / (cos(x) cos(y) - sin(x) sin(y))

tan(x + y) = (tan(x) + tan(y)) / (1 - tan(x) tan(y))

so that

tan(2θ) = 2 tan(θ) / (1 - tan²(θ)) = -(2√10)/3

Find the 66th term in the following
arithmetic sequence :
-92, -85, -78, -71, .

Answers

Answer

363

Step-by-step explanation

T1= a= -92

T2= -85

common difference d = T2-T1

d = -85 -(-92)

= -85 +92

= 7

Tn = a + (n-1)d

T66 = -92 + (66-1)7

= -92 + (65)7

= -92 + 455

= 363

Find the area and circumference of the circle if It is 13 in

Answers

Answer:

Area: 531 in²

Circumference: 82 in

Step-by-step explanation:

Given:

radius = 13 inchesπ = 3.14round to nearest whole number

To find:

AreaCircumference

Area of Circle:

[tex]\displaystyle \large{A=\pi r^2}[/tex]

A = area

Therefore:

[tex]\displaystyle \large{A=3.14 \cdot 13^2}\\\displaystyle \large{A=530.66 }[/tex]

Round to nearest whole number:

If the digit is at least or greater than 5, round to 1.If the digit is less than 5, don’t do anything.

Therefore, the area is 531 inches squared

Circumference of Circle:

[tex]\displaystyle \large{C=2\pi r}[/tex]

C = circumference

Therefore:

[tex]\displaystyle \large{C=2\cdot 3.14 \cdot 13}\\\displaystyle \large{C=81.64}[/tex]

Round to nearest whole number:

Hence, the circumference is 82 inches

Answers

They are exempt from income tax and we would get the income tax withheld as $340

What is income tax?

Income tax is a tax applied on individuals or entities concerning income or profit earned by them.

You earn $1,166 gross taxable income every week and have claimed no exemptions. assuming that you have no other sources of income.

Gross taxable Income = $ 1,166

Rate of Income tax = 30%

Amount of income tax = 30 % of 1,166

 = 30/100 × 1,166

= $339.6

= $340

Therefore. they are exempt from income tax and we would get the income tax withheld as $340.

Which sum is rational?
A. 1 + 18
B. 25 + 1.75
C. V3 + 5.5
D. I+V2

Answers

Answer: B. √25 + 1.75.

Step-by-step explanation: Rational Numbers are numbers that terminate or don't need to be terminated.  For example, 1/3 is a repeating number, but we can terminate the value, whereas pi is never ending, and there is no terminating with that value.  Numbers like 5.56 and 7/8 are rational because they don't need to be terminated to be rational.  √25 is 5, no decimals to terminate or anything, and that makes the value rational.  1.75 is also rational, and that's why equation c is fully rational.  √3 and √2 can't terminate, because both are 1.73205080757 and 1.41421356237, which means that they still can't terminate.  Pi cannot terminate, so that's why the answer choices with pi aren't rational.

The number of links on a chain is proportional to the length of the chain. If 25 links create a chain that is 21.25 inches long, than how many links are in a chain that is 80.75 inches long

Answers

Answer:

95

Step-by-step explanation:

21.25 times 4 is 85

so it's 3 point something

then you do 80.75 divided by 21.25 and get 3.8 and then 25 times 3.8 is 95

Links are in a chain that is 80.75 inches long are 95.

The number of links on a chain is proportional to the length of the chain.

If 25 links create a chain that is 21.25 inches long,

then how many links are in a chain that is 80.75 inches long.

What are the inches?

The inch can be defined as a unit of length in the customary system of measurement.

21.25 times 4 is 85.

Then you divided 80.75 by 21.25.

[tex]\frac{80.75}{21.25} =3.8[/tex]

Then 25 times 3.8 is 95
