Do they represent a function or not a function

Answer:120

Step-by-step explanation:

Answer:

105

Step-by-step explanation:

180 - 140 = 40

180 - 145 = 35

35+ 40 = 75

180 - 75 = 105

a = 5

Answer:

105

Step-by-step explanation:

interior angle next to 145 is 180-145=35

interior angle next to 140 is 180-140=40

angle a= 180-35-40=105

Answer:

(a).The volume of cube is changing at the rate [tex]450 cm^3/s[/tex]

Step-by-step explanation:

Let x be the side of cube

[tex]\frac{dx}{dt}=6 cm/s[/tex]

We have to find the rate at which  volume of cube changing when edge is 5 cm.

We know that

Volume of cube, V=[tex]x^3[/tex]

Differentiate w.r.t t

[tex]\frac{dV}{dt}=3x^2\frac{dx}{dt}[/tex]

Substitute the values

[tex]\frac{dV}{dt}=3(5)^2\times 6[/tex]

[tex]\frac{dV}{dt}=450 cm^3/s[/tex]

Hence, the volume of cube is changing at the rate [tex]450 cm^3/s[/tex]

x=13

Step-by-step explanation:

answer: 20

in the number line, you can see that the dot on 20 is an open circle. this means that it is not included. so 20 could be one of the answers.

- anything greater than 20 would be an answer.

Answer:

12 dimes

Step-by-step explanation:

Let :

Dime = x

Nickel = y

Dime is worth 10 cent = $0.1

Nickel is worth 5 cent = $0.05

x + y = 28 - - - (1)

0.1x + 0.05y = 2 - - - (2)

From (1)

x = 28 - y

0.1(28 - y) + 0.05y = 2

2.8 - 0.1y + 0.05y = 2

2.8 - 0.05y = 2

2.8 - 2 = 0.05y

0.8 = 0.05y

y = 0.8 / 0.05

y = 16

x = 28 - 16

x = 12

Answer:

1. V(12) = $ 1200

2. V(20) = $ 4800

Step-by-step explanation:

The following data were obtained from the question:

V(t) = 150 × 2ᵗ/⁴

V(12) =?

V(20) =?

1. Determination of V(12)

Time (t) = 12 years

V(12) =?

V(t) = 150 × 2ᵗ/⁴

V(12) = 150 × 2¹²/⁴

V(12) = 150 × 2³

V(12) = 150 × 8

V(12) = $ 1200

2. Determination of V(20)

Time (t) = 20 years

V(20) =?

V(t) = 150 × 2ᵗ/⁴

V(20) = 150 × 2²⁰/⁴

V(20) = 150 × 2⁵

V(20) = 150 × 32

V(20) = $ 4800

Answer:

B. add the opposite of four

Step-by-step explanation:

x + 4 = 6

x + 4 - 4 = 6 - 4

x + 0 = 2

x = 2

Answer:

y = 12665 (100⁻¹)  + b

Step-by-step explanation:

To model this relationship, you're to write the equation of a line; in the form

y = mx + b

Now let y represent the full coupon value,

mx represent the amount spent by Hellen and her sister

and b, the change that's left on the coupon.

So, the summary of Hellen's transaction is:

$85.2 became $(85.2 - 12.78) which is  =  $72.42

The summary of her sister's transaction is:

$63.8 became $(63.8 - 9.57) which is  =  $54.23

So   y - (72.42 + 54.23) = b

y - 126.65 = b

y = 126.65 + b

Separating m from x in mx, you have

y = 12665 x 1/100  + b

y = 12665 (100⁻¹)  + b

Where m = 12,665   and x = 100⁻¹

Answer:

The angular speed of the blade is of 166.67 rad/min

Step-by-step explanation:

The velocity, is given by the following equation:

[tex]v = rw[/tex]

In which r is the radius and w is the angular speed.

We use this relation to solve this question;

We have that:

[tex]v = 1000, r = 6[/tex]. We want to find w. So

[tex]v = rw[/tex]

[tex]1000 = 6w[/tex]

[tex]w = \frac{1000}{6}[/tex]

[tex]w = 166.67[/tex]

The angular speed of the blade is of 166.67 rad/min

Answer:

For tree A: 24+10t

For tree B: 36+7t

They are at the same height at 4 years at a height of 64 inches

Step-by-step explanation:

To figure out when the trees are at the same height make the equations equal to each other and solve for T

24+10t=36+7t

Subtract 24 and 7t from both sides to get

3t=12

divide by 3 to get

t=4

This means at t=4 they are at equal height so we plug this into any of the equations

24+10*4

this is equal to 64

We can double check by plugging t=4 into the second equation

36+7*4

36+28=64

Answer:

$27.69

Step-by-step explanation:

Given

Monthly budget (See attachment)

[tex]Month = 4\ weeks[/tex]

[tex]Week = 40 \ hour[/tex]

Required

Determine the closest hourly wage

From the attachment, the monthly budget is:

[tex]Budget = \$ 4430[/tex]

First, we calculate the closest weekly earnings.

Since a month = 4 weeks.

Then

[tex]Weekly\ Earnings = \frac{\$4430}{4}[/tex]

[tex]Weekly\ Earnings = \$1107.5[/tex]

Next, we calculate the hourly earnings:

Since 1 week = 40 hour

Then

[tex]Hourly\ Earnings = \frac{\$1107.5}{40}[/tex]

[tex]Hourly\ Earnings = \$27.6875[/tex]

From the list of options, the closest is: $27.69

In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.
