If f (x) = x-5 and g(x) = 4x what is the value off [g(4)]?​

Answers

Answer 1

Step-by-step explanation:

f[g(4)]

g(x) = 4x

g(4) = 4(4)

= 16

f(x) = x-5

f[g(4)] = f(16) = 16 - 5 = 11

So, f[g(4)] = 11

what is the explicit formula

Answers

Answer:

a(n) = 13 - 2n

Step-by-step explanation:

The explicit formula variables are a(n) = a(1) + d (n - 1). The a(1) is your number you started out with, and the d is the common difference. From the recursive formula example, you see that your first number is 11 and your difference is -2.

1. Plug the numbers into the equation : a(n) = 11 - 2 (n - 1)

2. Distribute: a(n) = 11 - 2n + 2

3. Add like terms: a(n) = 13 - 2n

If you want to double check, you can plug 1 into n and see if you get 11. I did this, and I did so it should be correct. Hope this made sense! Have a great day :)

Find the 58"" term of the following arithmetic sequence,
18, 23, 28, 33,

Answers

Answer:

303

Step-by-step explanation:

So the equation to find a term is An=a1+(n-1)d

An represents the value of the number (n)

and n is the selective that you want

d is the difference between the first and second term which is 23-18=5, and you can see that adding 5 to the previous term gives the following term.

a1 is the first term in the sequence

so knowing all that now you can go back and inset all variables into the equation

An=18+(58-1)5

An=303

Hope that helps :)

i’m confused on how to do this

Answers

Answer:

68°

Step-by-step explanation:

The sum of all internal angles of a circle always total 360°.

So, we can add the three angles (ADB, BDC, ADC) and equate them to 360°.

90 + (2x+1) + (2x-3) = 360

90 + 4x -2 = 360

4x - 2 = 360 - 90

4x - 2 = 270

4x = 272

x = 272/4

x = 68°

From here, you can find any of the two unknown angles by simply plugging in x = 68°.

Each box contains 4 toys; a 5-ounce truck and three bags of marbles. The bags of marbles are all identical. How much does each bag of marbles weigh

Answers

Answer:

15 ounces

Step-by-step explanation:

Each box contains 4 toys; a 5-ounce truck and three bags of marbles. The bags of marbles are all identical. How much does each bag of marbles weigh?

We need the total weight of the box. This is not given in the question, hence:

Let us assume

The total weight of the = 50 ounces

A 5-ounce truck and three bags of marbles.

Let the weight of one bag of marble = x

Hence,

5 ounces +3x = 50 ounces

3x = 50 ounces - 5 ounces

3x = 45 ounces

x = 45 ounces/3

x = 15 ounces

Therefore, the weight of each bag of marble is 15 ounces

Given: ⅓ (18x + 27) = 81 Prove: x = 12

Answers

Answer:

Firstly, rewrite the equation:

⅓ (18 + 27) = 81

Substitute x for the given number of it's supposed equivalent.

In this case x = 12.

⅓ (18(12) + 27) = 81

Solve using PEMDAS and simplify what is in the parenthesis first. Then, multiply.

(18 x 12) + 27 = 243

Now, solving using PEMDAS, multiply the total of what you got that was originally in the parenthesis by ⅓ .

⅓ (243) = 81

When you multiple these number they are equivalent to 81.

81 = 81

Since the equation given, when substituted x for 12, is equivalent to 81, this proves that substituting x for 12 makes this equation true.

A rectangle has dimensions 8 1/5 in by 13 in. A diagonal of the rectangle forms two matching right triangles. What is the area of one of the triangles.

The area of one of the triangle is ____ in.

Answers

Answer:

53.3 in^2

Step-by-step explanation:

Given data

Base B= 13in

Height H= 8 1/5 in= 41/5in

The expression for the area of a triangle is

Area= 1/2 Base * Height

Substitute

Area= 1/2* 13* 41/5

Area= 6.5*41/5

Area= 266.5/5

Area= 53.3 in^2

Hence the area is 53.3 in^2

Step-by-step explanation:

ok im assuming youre trying to find how many hours he worked so

our equation is y = 15x + 6

solve for x

120 = 15x

8 = x

so he worked for 8 hours

Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed.
