Answer:

-0.6

Step-by-step explanation:

Answer:

- 1, 2, 5, 8, 11

Step-by-step explanation:

Substitute n = 1, 2, 3, 4, 5 into the n th term formula

a₁ = 3(1) - 4 = 3 - 4 = - 1

a₂ = 3(2) - 4 = 6 - 4 = 2

a₃ = 3(3) - 4 = 9 - 4 = 5

a₄ = 3(4) - 4 = 12 - 4 = 8

a₅ = 3(5) - 4 = 15 - 4 = 11

The first 5 terms are - 1, 2, 5, 8, 11

Final answer:

The first 5 terms of the sequence an = 3n - 4 are -1, 2, 5, 8, and 11. Each term is found by substituting the nth term number into the expression and calculating its value.

Explanation:

The student has asked to write the first 5 terms of the sequence an = 3n - 4. To find the terms of this sequence, we simply substitute the values of n (starting from 1 and going up by 1 each time) into the expression and calculate the results.

Therefore, the first 5 terms of the sequence are -1, 2, 5, 8, 11.

Answer: The amount of carbon-14 remaining after 4 years is 99.95 grams.

Step-by-step explanation:

Hi, to answer this question we simply have to substitute t=4 in the equation given and solve for c.

c= 100 (0.99988)^t

c =100 (0.99988)^4

c = 100 x 0.999520086

c= 99.95200864 ≅99.95 grams (rounded)

The amount of carbon-14 remaining after 4 years is 99.95 grams.

Feel free to ask for more if needed or if you did not understand something.

The amount of carbon-14 remaining after 4 years is 99.95 grams.

Given that,

The amount c in grams of a 100-gram sample of carbon-14 remaining after t years is represented by the equation,

[tex]\rm c = 100(0.99988)^t[/tex]

We have to determine,

The amount of carbon-14 remaining after 4 years.

According to the question,

Equation; [tex]\rm c = 100(0.99988)^t[/tex]

Where the amount c in grams of a 100-gram sample of carbon-14 remaining after t years is represented by the equation,

To determine the amount of carbon-14 remaining after 4 years following all the steps given below.

Then,

The amount of carbon-14 remaining after 4 years is,

[tex]\rm c = 100(0.99988)^t\\\\\rm c = 100(0.99988)^4\\\\ c = 100 \times 0.999520086\\\\c = 99.95 \ gram[/tex]

Hence, The amount of carbon-14 remaining after 4 years is 99.95 grams.

Answer:

(5,8)

Step-by-step explanation:

(x,y) --> (x,-y)

The image of the point (5, -8) after a reflection over the x-axis is (5, 8).

When reflecting a point over the x-axis, the x-coordinate remains the same while the y-coordinate changes sign. Given the point (5, -8), after a reflection over the x-axis, the new coordinates will be (5, 8).

Here's the step-by-step process:

Keep the x-coordinate the same (x remains 5).

Change the sign of the y-coordinate (-y becomes 8).

Combine the new coordinates to get the reflected point (5, 8).

Therefore, the image of the point (5, -8) after a reflection over the x-axis is (5, 8).

Answer:

A. x=1, y=3

Step-by-step explanation:

you have to isolate y in the bottom equation in order to put it into the top equation. heres what i did:

we will start with the bottom equation, x+y=4. then, subtract x on both sides of the equation. this will isolate y. now, we have the equation; y=4-x.

next, we are going to substitute our new bottom equation in where y is on the top. it looks like this: 2x+(4-x)=5. then, we are going to get rid of the parenthesis, so our equation is: 2x+4-x=5. to solve this, we have to combine like terms, so we will combine the x terms: x+4=5. now, isolate the variable. to do this, we have to take away 4 from each side so we can get x alone: x=1.

so now that we have a value for x, we can use that to find y. we can actually substitute our x-value into the bottom equation to make it easier: 1+y=4. next, we have to isolate the variable, which is y. this gives us the final answer: y=3.

i hope that this explanation helped with your struggles, it took me awhile to type out and i really tried hard. stay safe and good luck with your class!

Answer:

6/60

Step-by-step explanation:

The probability that Lin gets another turn, P(E) could be 6/60

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

We are given that Lin plays a game that involves a standard number cube and a deck of ten cards numbered 1 through 10.

Therefore,

P(E) = Number of favorable outcomes / total number of outcomes

Outcomes of cube = { 1, 2, 3, 4, 5, 6}

Outcome of Card = {1, 2, 3} from each group.

when both the cube and card have the same number, then Lin gets another turn.

The probability that Lin gets another turn, P(E) =6/60

Answer:1197m³

Step-by-step explanation:

Answer:

Volume of a triangular irregular prism=1300.16m^3 = 1300m^2

Volume of a rectangular prism two answers =  1197m^3 or  1233m^3

Step-by-step explanation:

With rectangular prism two answers we need the rectangle surface area first

A = 9 m x 19 m = 171m

or A = 7 m x 19m

The rectangle prism could be 1197m^3  or 1233m^3

depending how big the rectangle is as we calculate that first then multiply by depth. If we had the direction of measurement of the base we would just get one answer and not two.

Rectangular prism A = 171sq  

V = 1197m^3    =  (171sq x 7)

or V=  1233m^3  = 137sq x 9

If the prism is a irregular prism we add the surface area's

V = (a+b+c)B/3

V = (7x19)(9x7) (9x19) x B = 133 + 63 + 197 x 197  =  3900.5/3 =1300.16

Given:

The box plots show daily low temperatures for a sample of days in two different towns.

We need to determine the most appropriate comparison of the spreads.

Interquartile range of town A:

The interquartile range can be determined by subtracting the end values of the boxes.

Thus, we have;

Interquartile range = 40 - 20

Interquartile range = 20

Thus, the interquartile range for town A is 20.

Interquartile range for town B:

The interquartile range for town B is given by

Interquartile range = 45 - 35

Interquartile range = 10

Thus, the interquartile range for town B is 10.

Hence, the interquartile range (IQR) for town A, 20° is greater than the IQR for town B, 10°

Hence, Option A is the correct answer.

Answer: (consider leaving a thanks)

Since the equation representing the total cost is C, we would write:

C = (rest of equation will go here)

Then, since the price goes up with the number of hours (h) by 65$ each hour, we would write it as (65h)

C = 65h (Final part!)

Finally, since 150$ is added on, and isn't connected to the number of hours we would write the equation like this:

C = 65h + 150

Here are the answer: a) R = 3.6 and b) A = 2

Step-by-step explanation:

Given,

R is inversely proportional to A.

R ∝ [tex]\frac{1}{A}[/tex]

so, R = [tex]\frac{k}{A}[/tex]  -------eq 1 where k is any constant

To find the values of a) R when A = 5 and

b) Value of A when R = 9

Now,

Putting R = 12 and A = 1.5 in eq 1 we get,

12 = [tex]\frac{k}{1.5}[/tex]

or, k = 12×1.5 = 18

From eq 1 we get,

R = [tex]\frac{18}{A}[/tex] --------- eq 2

Now,

a) Putting A= 5 in eq 2 we get,

R = [tex]\frac{18}{5}[/tex] = 3.6

b)  Putting R = 9 in eq 2 we get

R = [tex]\frac{18}{A}[/tex]

or, A = [tex]\frac{18}{9}[/tex] = 2

Answer:

a.3.6

b. 2

Step-by-step explanation:

R is inversely proportional to A

Which means R=k/A

Cross multiply

k=RA

Since R=12

A=1.5

So k=12×1.5

=18

a. We are to determine the value for R

So R=k/A

=18/5

=3.6

b.we are to determine the value for A

So R=k/A

A=k/R

=18/9
