A circle has a diameter of 14cm. find the arc length if the central angle is 50°. Round to the nearest tenth.

Answer:

Perpendicular: 4, Parallel: -1/4

Step-by-step explanation:

The slope of a line perpendicular to the given line is the opposite inverse of the slope to the line.

First write the equation of the line in slope-intercept form

-x-4y=7

-4y=x+7

y=-(1/4)x-7/4;

The slope to the line is -1/4; Now find the slope of the perpendicular line;

-(-1/4)^-1 = 4

4

The slope of a line parallel to a line is the same as the given slope;

when we calculated the given slope, it was -1/4

The slope of the line parallel to this line is also -1/4

-1/4

Answer:

3rd option : 1455

Step-by-step explanation:

here, a = 5, d = 3 , tn = 92, n = ?, Sn = ?

tn = [a + (n - 1) d]

92 = [ 5 + (n - 1)d

92 = 5 + 3n - 3

92 - 5 + 3 = 3n

90 = 3n

n = 90/3

n = 30

By sum of first n terms of an A. P formula,

Sn = n/ 2 [ 2a + (n - 1) d]

Sn = 30/2 [ 2 * 5 + (30 - 1) 3]

Sn = 15[ 10 + 29 ( 3) ]

Sn = 15[ 10 + 87 ]

Sn = 15( 97 )

Sn = 15 * 97

Sn = 1455

Therefore, option 3rd 1455 is correct.

Step-by-step explanation:

Volume = lwh

120 = l(4)(3)

l = 10 feet

(B) x = 40

Step-by-step explanation:

4x + 20 = 180

4x = 160

x = 40

Answer:

B. 40

Step-by-step explanation:

This is a straight angle; this means that 20 and 4x are supplementary angles.

SUPPLEMENTARY ANGLES: TWO ANGLES WITH A SUM OF 180°.

[tex]20 + 4x = 180.[/tex]

First, subtract 20 from 180 and from 20.

[tex]20 - 20 = 0[/tex] (cancels itself out).

[tex]180 - 20 = 60.[/tex]

Now we are left with 4x = 160.

Lastly, divide 160 from 4.

[tex]160/4 = 40.[/tex]

Therefore, the value of x is 40.

Answer:

C. III only

Step-by-step explanation:

a quadratic function means that as the maximum power in its arguments it is squaring 1 or more items.

so, let's look at the tables.

table I shows the powers of 2. y = 2^x

2^0 = 1

2^1 = 2

2^2 = 4

2^3 = 8

so, it is not saying anything in general.

table II shows an "identity" equation. y = x

0 = 0

1 = 1

2 = 2

3 = 3

this does not square anything.

table III shows then finally a square equation. y = x^2

0^2 = 0

1^2 = 1

2^2 ≈ 4

3^2 = 9

hurray !

Answer:

21 and 16

Step-by-step explanation:

x= big number

x`-5 = small number

x + x-5 = 37

2x-5 =37

2x= 42

x = 21

       21-5 = 16

21+16 = 37

Answer:

A≈10.83cm²

Step-by-step explanation:

Unit Conversion:

P=15cm

Using the formulas

A=3

4a2

P=3a

Solving forA

A=3P2

36=3·152

36≈10.82532cm²

Answer:

10.8 cm^2 to nearest tenth.

Step-by-step explanation:

You can use Hero's formula to do this:

Area = √[s(s-a)(s-b)(s-c)]   where s = semi-perimeter,  a b and c are the lengths of the 3 sides,

Here s = 15/2 = 7.5 and a, b and c = 5.

area = √(7.5 * 2.5 * 2.5 * 2.5)

= √117.1875

= 10.8253.

Another method would be to use trigonometry

h = 5 sin 60 and 1/2 * base = 1/2 * 5 = 2.5

So area = 5 sin60 * 2.5 = 10.8253,

Answer:

[tex]\frac{96}{91}[/tex] or 51.69

Step-by-step explanation:

[tex]\frac{-6}{13}[/tex] x reciprocal of [tex]\frac{-7}{16}[/tex]

Reciprocal of [tex]\frac{-7}{16}[/tex] is [tex]\frac{-16}{7}[/tex]

So, the equation would be:-

[tex]\frac{-6}{13}[/tex] x [tex]\frac{-16}{7}[/tex]

= [tex]\frac{96}{91}[/tex]

The product would be [tex]\frac{96}{91}[/tex].

Answer:

3.6 dollars

Step-by-step explanation:

Lets go over what we know:

Each ounce of penut butter cost 0.2$, or 1/5$

We need 18 ounces.

To solve this, lets multiply the cost per ounce by the amount of ounces:

0.2*18

Or

1/5*18

=

18/5

This can be simplfied into:

3 3/5

We know each 1/5 is 20 cents(0.2), so 3 cents would be 3*0.2 = 0.6:

3.6 dollars

So the answer is for 18 ounces, it cost 3.6 dollars.

Hope this helps!

Step-by-step explanation:

Answer:

f(6)=42

Step-by-step explanation:

We know that the equaiton is f(x)=2x+3(x+4). So that means when it is f(6), we plug in 6 into all of the x. Therefore, the equation will be f(6)=2(6)+3(6+4). We combine like terms to get f(6)=12+3(10). We do 3x10 which is equal to 30. f(6)=30+12. 30+12=42. f(6)=42. Therefore, f(6)=42.

Answer: 47

Step-by-step explanation:

That just means replace the x’s with 6 in the equation. So 2*6+3(6+4)+5. 6+4 is 10, 2*6 is 12. So the equation is now 12+3(10)+5. 3*10 is 30. 12+30+5=47.

Answer:

12 months

Step-by-step explanation:

Theres an awful amount of needless information to get through.

Only the last paragrph is needed.

C(t) = 180 + 10t

C(t) = 25t

Set the equations equal

25t = 180 + 10t

Subtract 10t from both sides

15t = 180

Divide both sides by 15

t = 12

Answer:

(7, 4)

Step-by-step explanation:

The solution to the system of the 2 equations represented on the graph by the two lines is the c

x and y coordinates of the point where the two lines intersect.

They intersect at when x = 7, y = 4.

Therefore, the solution to the system of equations would be (7, 4).
