For the following right triangle, find the side length x. Round your answer to the nearest hundredth.

Answer:

​

h(1)=−31

h(n)=h(n−1)+(−7)

​

Step-by-step explanation:

I got it wrong- and then i found the answer :)

The recursive function is h(n) = h(n−1 ) + (−7) where h(1) = −31.

A rule defined such that its definition includes itself.

Example:

F(x) = F(x-1) + c is one such recursive rule.

Given;

h(1) = −31

This means that the function h(n) has the following parameters:

First term = −31

Rate = -7

Hence, the recursive function is h(n) = h(n−1 ) + (−7) where h(1) = −31.

Answer:

  5

Step-by-step explanation:

The number of cells in a tile is 4, so the board dimension cannot be odd, but must be a multiple of 2 in order to have the number of cells divisible by 4.

If the tiles are colored in an alternating pattern, tiles must have 3 of one color and 1 of the alternate color. Hence the total number of tiles used to cover a board must be even (so the numbers of each color match). Then the board dimension must be divisible by 4.

In the given range, there are 5 such boards:

  4×4, 8×8, 12×12, 16×16, and 20×20

Answer:

Answer: The vertex of the function is (-1, -7).

Step-by-step explanation: We are given to find the vertex of the following function.

We know that the vertex of the function is given by (h, k).

So, for the given function f(x), the vertex will be (-1, -7).

The graph of the function f(x) is shown in the attached figure, where the vertex is at the point (-1, -7).

Thus, the vertex of the function is (-1, -7).

The vertex of the function  f(x) = |x + 1| - 7 is (-1,-7)

The function is given as:

f(x) = |x + 1| - 7

The above function is an absolute value function

An absolute value function is represented as:

f(x) = a|x – h| + k

Where, the vertex is (h,k)

So, we have:

(h,k) = (-1,-7)

Hence, the vertex of the function  f(x) = |x + 1| - 7 is (-1,-7)

Answer:

-7, -10

Explanation:

To solve this problem we must first understand what the pattern is in the sequence. Once we understand the pattern, we can then apply it to the final known term to find the next two terms.

Take a look at the sequence given:

8, 5, 2, -1, -4,...

Let's start by figuring out how they got the second term in the sequence. To do that, identify what basic operation and number must be applied. This will reveal the pattern.

8 - first term

5 - second term

8 ? ? = 5

8 - 3 = 5

So, this means they subtracted three to get the next term. Therefore, the pattern should be 'subtract three' to get the next term. Just to be sure the pattern we found is correct, apply it to the given sequence.

8, 5, 2, -1, -4,...

8 - 3 = 5

5 - 3 = 2

2 - 3 = -1

-1 - 3 = -4

So, since 'subtracting three' every time gives us the next term, the pattern is correct.

Finally, let's continue the pattern to find the next two terms.

-4 - 3 = -7

-7 - 3 = -10

Therefore, the next two terms in the sequence are -7, -10.

[tex]Orange\ area = A^2(\sqrt{3}/4 - \pi/8) = 0.0403A^2[/tex]

Step-by-step explanation:

First let's find the area of the triangle, using the formula:

[tex]Area\_triangle = side^2\sqrt{3}/4[/tex]

[tex]Area\_triangle = A^2\sqrt{3}/4[/tex]

Now, let's find the area of each circular sector of 60° (internal angle of a equilateral triangle):

[tex]Area\_sector = \pi*radius^2*60/360[/tex]

[tex]Area\_sector = \pi*(A/2)^2/6[/tex]

[tex]Area\_sector = \pi*A^2/24[/tex]

Now, To calculate the orange area in the center, we have:

[tex]Orange\ area = Area\_triangle - 3*Area\_sector[/tex]

[tex]Orange\ area = A^2\sqrt{3}/4 - \pi*A^2/8[/tex]

[tex]Orange\ area = A^2(\sqrt{3}/4 - \pi/8)[/tex]

[tex]Orange\ area = 0.0403A^2[/tex]

Answer:

Step-by-step explanation:

Option B : ∠A+∠D = 180°

Given below diagram is of a parallelogram.

A parallelogram is defined as a closed geometric figure that has got 4 straight sides and  opposite sides are parallel to each other.

One of the properties of a parallelogram is that its adjacent angles are supplementary.

Adjacent angles means angles which are either on the just left side or just right side.,

Supplementary angles are those which if added gives 180° as value.

Option A and D are not correct here.

Option C is wrong as adjacent sides of a parallelogram are never parallel.

Taking the angles ∠A and ∠D, we see they're adjacent. And since ABCD is a parallelogram, thus by its property, we've got ∠A+∠D = 180°.

Thus option B: ∠A+∠D = 180° is correct.

Independent variable = t

Dependent variable = N

Step-by-step explanation:

Given that the function N(t)=100+15t represents the relation between the number of unread emails, N, and the time, t, measured in days

The independent variable is an input which can be controlled. In the function

N(t)=100+15t

The independent variable is t

While the dependent variable is the output of a function when independent variable has been substituted.

In the function N(t)=100+15t

The number of unread messages depends on the number of time t measured in days as the number of unread messages N is a function of t.

Therefore, the independent variable is N.

A function is a law that derives a relation between two variables.

The function is f(x) = 6x+11

g(x) = x² +6

The operation f(g(x)) = 6 (x² +6) +11

f(g(x)) = 6x² +36 +11

f(g(x)) = 6x² +47

Answer:

[tex]Dina= 35[/tex]

Step-by-step explanation:

Given

[tex]Ratio = 4:2:5[/tex]

Peter = 14 more A's than Chris

Required

How many A’s did Dina get?

The order of the ratio is Peter: Chris: Dina

This implies that

[tex]Peter: Chris: Dina = 4:2:5[/tex]

Considering Peter and Chris

[tex]Peter: Chris = 4:2[/tex]

Let the number of Chris' A's be represented by A

This implies that:

Peter's = 14 + A

And as such;

[tex]14 + A : A = 4 : 2[/tex]

Convert ratio to division

[tex]\frac{14 + A}{ A} = \frac{4}{ 2}[/tex]

Multiply both sides by A

[tex]A * \frac{14 + A}{ A} = \frac{4}{ 2}* A[/tex]

[tex]14 + A = \frac{4}{ 2}* A[/tex]

[tex]14 + A = 2* A[/tex]

[tex]14 + A = 2 A[/tex]

Subtract A from both sides

[tex]14 + A-A = 2 A-A[/tex]

[tex]14 = A[/tex]

This means that;

Chris answered 14 while Pete answered 28 (14 + 14)

Considering Chris and Dana

[tex]Chris :Dana = 2:5[/tex]

Replace Chris with 14

[tex]14:Dana = 2:5[/tex]

Convert ratio to division

[tex]\frac{14}{ Dina} = \frac{2}{5}[/tex]

Cross Multiplication

[tex]Dina * 2 = 14 * 5[/tex]

Divide both sides by 2

[tex]\frac{Dina * 2}{2} = \frac{14 * 5}{2}[/tex]

[tex]Dina= \frac{14 * 5}{2}[/tex]

[tex]Dina= \frac{70}{2}[/tex]

Answer choice is B) 10

Yes they are independent because P(California) = 0.55 approximately and P(California | Brand B) = 0.55 approximately as well

===================================================

Explanation:

P(California) is notation that means "probability the person is from California". There are 150 people from California out of 275 total. Therefore, the probability is 150/275 = 0.5454 approximately which rounds to 0.55

Now if I told you "this person prefers brand B", then you would focus your attention solely on the brand B column. The other columns are ignored because you know they don't prefer anything else. With this narrower view, we see that 54 Californians prefer this brand out of 99 total. The probability becomes 54/99 = 0.5454 which rounds to 0.55. We get the same as before.

The notation P(California | Brand B) means "the probability they are from California given they prefer brand B". The vertical line is not the uppercase letter i or lowercase letter L. It is simply a vertical line. In probability notation that vertical line means "given".

We've shown that P(California | Brand B) = 0.55 approximately. The fact that they prefer brand B does not change the original probability. So the two events are independent. If liking brand B did change the probability, then the events would be dependent.

x=5 years

first we need to set the equation

at plug in all the information we have. In our case, we know cars value or y =9000, we need to find what is the x value

2

we need to subtract 24000 on both sides, and then divide by -3000 on both sides, and find out for x in years

Step-by-step explanation:

The model of the car's value, y, in dollars, after x years is:

y = -3000x + 27000

The equation of a straight line is given by:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let x represent the number of years and y represent the value in dollars.

Since the new car worth is $27000, hence b = 27000. Also it depreciating in value by $3,000 per year, hence m = -3000. The car value is given by:

Step-by-step explanation:

in order to solve this problem we first need to find the rate of change, "k", to do that we will use the given information where the population was 1400 five years ago and its now 1000. Applying this data to the equation gives us:

[tex]A = A_0*e^{k*t}\\1000 = 1400*e^{5*k}\\1400*e^{5*k} = 1000\\e^{5*k} = \frac{1000}{1400}\\ln(e^{5*k}) = ln(\frac{1000}{1400})\\5*k = ln(1000) - ln(1400) \\k = \frac{ln(1000) - ln(1400)}{5} = -0.06729[/tex]

We now know the value for "k", we can estimate how many years it will take for the bird population to dip below 100. We have:

[tex]100 = 1000*e^{-0.06729*t}\\e^{-0.06729*t} = \frac{100}{1000}\\ln(e^{-0.06729*t} = \frac{1}{10}\\-0.06729*t = ln(0.1)\\t = -\frac{ln(0.1)}{0.06729} = 34.22[/tex]

Resistance of 8 feet wire = 0.81 Ω

Step-by-step explanation:

Equation representing the relation between the resistance and length of a cylindrical shaped wire is,

R = ρ.[tex]\frac{l}{A}[/tex]

Here R = Resistance of the cylindrical wire

ρ = Resistivity of the material

l = Length of the wire

A = Cross sectional area of the wire.

If length of the wire = 160 ft

Resistance = 16.2 Ω

By substituting these values in the formula,

16.2 = ρ.[tex]\frac{160}{A}[/tex]

ρ = [tex]\frac{16.2\times A}{160}[/tex]

Similarly, if length of the same wire = 8 ft

From the given formula,

R = ρ.[tex]\frac{8}{A}[/tex]

R = [tex]\frac{16.2\times A}{160}\times \frac{8}{A}[/tex]

  = 0.81 Ω

Therefore, resistance of 8 feet wire will be 0.82 Ω.
