Write a recursive formula for 16, 9, 7, 2, 5

Answers

Answer 1
Notice that:

7=16-9
2=9-7
5=7-2

the next term would be: 2-5=-3

so each term of the sequence is equal to its previous term, subtracted from the second previous term:

Also, in order to describe the formula, we need to express the 2 first terms, 1 is not enough.

The recursive formula is:

[tex]a_1=16[/tex]
[tex]a_2=9[/tex]
 [tex]a_n_2=a_n_1-a_n[/tex]

How many kilometers can the prius travel on 16 liters of gasoline?

Answers

Prius can travel up to 4.23 × x kilometers on 16 liters of gasoline.

It is given that Prius runs on gasoline.

We have to find out that how many kilometers it can run if amount of gasoline is 16 liters.

What will be the value of 16 times of a number x ?

The value will be ; 16 × x .

No. of kilometers Prius travels depends on what is the model of Prius . Also quality of roads makes a difference.

1 liter = 0.264172 gallons

16 liters = 16 × 0.264172 = 4.23 gallons

Let's say a Prius travels x kilometers per gallon.

So ; on 16 liters of gasoline , Prius will travel ;

x × 4.23 = 4.23 × x kilometers

Thus , Prius can travel up to 4.23 × x kilometers on 16 liters of gasoline.

Describe the transformation f(x) = √x + 1 − 5 in words. The parent function f(x) = √x has been shifted 1 unit and 5 units.

Answers

Answer:

We are given,

The transformed function is [tex]f(x)=\sqrt{x+1}-5[/tex].

So, we can see that,

The parent function is [tex]f(x)=\sqrt{x}[/tex].

Then, we have,

The parent function is translated 1 units to the left to give [tex]\sqrt{x+1}[/tex].

Then, it is translated 5 units downwards to give the function  [tex]\sqrt{x+1}-5[/tex].

Hence, we have,

The parent function [tex]f(x)=\sqrt{x}[/tex] is translated 1 unit to the left and 5 units down.

The parent function f(x) = √x has been shifted 1 unit left and 5 units down

The parent function of a square root function is represented as:

[tex]f(x) = \sqrt x[/tex]

When the function is shifted 1 unit left, we have the following equation

[tex]f(x) = \sqrt {x + 1}[/tex]

When the function is shifted 5 units down, we have the following equation

[tex]f(x) = \sqrt {x + 1} - 5[/tex]

Hence, the parent function f(x) = √x has been shifted 1 unit left and 5 units down

What is the range of this function?

Answers

The answer is C. Just plug in the maximum and minimum domain values (because the function is linear, you don't have to worry about more complicated things happening in the middle) and be careful with the signs.

Answer:

c) -16 ≤ x < 5

Step-by-step explanation:

The given function is f(x) = -3x + 2 and domain is  -1 < x ≤ 6

The maximum value of the domain is 6 and the minimum value of the domain is -1.

To find the range, plugin the maximum and minimum value of the domain.

Plug in x = 6 in the given function, we get

f(6) = -3(6) + 2 = -18 +2 = -16

f(-1) = -3(-1) + 2 = 3 + 2 = 5

So the range is -16 ≤ x < 5

What is the following product

Answer: [tex] \sqrt[6]{200} [/tex]

Answer:

Option B.[tex]\sqrt[6]{200}[/tex]

Step-by-step explanation:

The given expression is ∛5.√2 and we have to find the product.

In this question ∛5 can be written as [tex]5^{\frac{1}{3} }[/tex] and [tex]\sqrt{2}=2^{\frac{1}{2}}[/tex]

We know to multiply these terms we should have the same powers of both the terms.

Now we will convert these terms to the terms having same powers.

first term [tex]5^{\frac{1}{3}}=5^{(\frac{1}{3}).(\frac{2}{2})}[/tex]

=[tex]5^{\frac{2}{6}}[/tex]

=[tex]25^{\frac{1}{6}}[/tex]

Second term √2 = [tex]2^{\frac{1}{2}}[/tex]

= [tex]2^{(\frac{1}{2}).(\frac{3}{3})}[/tex]

= [tex]2^{\frac{3}{6}}[/tex]

= [tex]8^{\frac{1}{6}}[/tex]

Now we multiply these terms

[tex]25^{\frac{1}{6}}.8^{\frac{1}{6}}[/tex]

= [tex]200^{\frac{1}{6} }[/tex]

Therefore option B is the answer.

an angle measures 12 degrees less than 3 times its supplement

Answers

Given that the angle measures 12 degrees less than 3 times the supplement, the size of the angle will be:
suppose the size of the supplement is x;
the size of the angle supplementary to x will be:
 3x-12
Given that the sum of supplementary angles is 180, thus;
x+(3x-12)=180
solving for x we get:
4x-12=180
4x=180+12
4x=192
x=192/4
x=48
the size of the supplementary angles will be:
48*3-12

How do you solve 3x+4y=12 and 2x=y-6

Answers

3x +4y =12

2x = y-6 Rewrite this as y = 2x+6

 now replace that for y in the first equation

3x + 4(2x+6) = 12

now do all the calculations:

3x + 8x +24 =12

11x + 24 = 12

11x = -12

x = -12/11 = -1 1/11

 now substitute -12/11 for x in the 2nd equation and solve

y = 2x+6

y = 2(-1 1/11) +6

y = 42/11 = 3 9/11

Given tan A = .78 find angle A in degrees. Round your answer to the nearest hundredth.

Answers

Tangent is one of the simplest trigonometric functions which relates the sides of the triangle. This function is the ratio between the measure of the side opposite to the angle and the side adjacent to it. This can be calculated through the reverse equation of,
             tan⁻¹(0.78) = A
The value of A in the equation to the nearest hundredth is 37.95°

Answer:

[tex]A\approx 37.95^{\circ}[/tex]

Step-by-step explanation:

We have been given that [tex]\text{tan}(A)=0.78[/tex]. We are asked to find measure of angle A in degrees.

We will inverse tangent to find measure of angle A as:

[tex]A=\text{tan}^{-1}(0.78)[/tex]

[tex]A=37.954230875133^{\circ}[/tex]

Upon rounding our answer to nearest hundredth, we will get:

Therefore, the measure of angle A is approximately 37.95 degrees.
