Answer: 243, 729

Step-by-step explanation:

1, 3, 9, 27, 81    is a geometric sequence where r = 3

a₁ = 1

a₂ = 1 x 3 = 3

a₃ = 3 x 3 = 9

a₄ = 9 x 3 = 27

a₅ = 27 x 3 = 81

To find the next two terms, multiply the previous term by 3:

a₆ = 81 x 3 = 243

a₇ = 243 x 3 = 729

The largest possible value for (a.bc + 0.d) is (10.56).

The largest possible value for (a.bc + 0.d) when (a), (b), (c), and (d) are replaced by four different digits from 1 to 9, inclusive, can be found by selecting the largest digits for (a), (b), and (c), and the smallest digit for (d).

This results in the number (9.86 + 0.7), which equals (10.56).

Therefore, the largest possible value for (a.bc + 0.d) is (10.56).

Complete question:

If a,b,c,d are replaced by four different digits from 1 to 9, inclusive, then what's the largest possible value for a.bc + 0.d ?

Answer:

[tex]x \leq 1[/tex]

Step-by-step explanation:

Multiplying 8 by x can be written as 8x, and +6 on end:

8x + 6

Because it says 14 is no less than, the equal to or more than sign needs to be used:

[tex]8x + 6 \leq 14[/tex]

The -6 can be moved over to the other side making it a -6:

[tex]8x \leq 14 - 6[/tex]

[tex]8x \leq 8[/tex]

Simplify by dividing both sides by 8:

[tex]x \leq 1[/tex]

Which is the inequality!

Answer:

The given statement can be written as [tex]14\geq 8x+6[/tex] or [tex]x\leq 1[/tex].

Step-by-step explanation:

It is required to write the sentence as an inequality.

The given sentence is "14 is no less than 8 times a number x plus 6".

The given statement can be written as " 14 can be equal or more than 8 times a number x plus 6"

Now, in the inequality form, the statement will be,

[tex]14\geq 8x+6[/tex]

Solve the above inequality as,

[tex]14\geq 8x+6\\8\geq 8x\\1\geq x\\x\leq 1[/tex]

Therefore, the given statement can be written as [tex]14\geq 8x+6[/tex] or [tex]x\leq 1[/tex].

Answer:

see explanation

Step-by-step explanation:

since y is inversely proportional to x the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of proportionality

to find k use the given condition when y = 7, x = 9

k = yx = 7 × 9 = 63

y = [tex]\frac{63}{x}[/tex] ← is the equation connecting them

when x = 21, then

y = [tex]\frac{63}{21}[/tex] = 3

The equation connecting y and x is y = 9 + 3x. When x = 21, y = 72.

The equation connecting y and x is given by y = 9 + 3x. In this equation, the constant term, also known as the y-intercept, is 9. The coefficient of x, also known as the slope, is 3. This means that for every increase of 1 in x, y increases by 3.

To calculate the value of y when x = 21, substitute x = 21 into the equation: y = 9 + 3(21) = 9 + 63 = 72. Therefore, when x = 21, y = 72.

Answer:

The solution to the system would be (3, -1)

Step-by-step explanation:

You can find the solution to this system by using the elimination method. To do that, start by multiplying the top equation by -5 and then adding it through.

-5x + 20y = -35

5x + 9y = 6

-----------------

29y = -29

y = -1

Now that we have the value of y, we can plug it into either equation and find the x value.

x - 4y = 7

x - 4(-1) = 7

x + 4 = 7

x = 3

Final answer:

The solution to the given system of equations is the ordered pair (3, -1).

Explanation:

To find the solution to the system of equations, we can use the method of substitution or elimination. Let's use the method of substitution.

1. Solve the first equation for x:

x = 7 + 4y

2. Substitute this value of x into the second equation:

5(7 + 4y) + 9y = 6

3. Simplify and solve for y:

35 + 20y + 9y = 6

29y = -29

y = -1

4. Substitute the value of y back into the first equation to find x:

x = 7 + 4(-1)

x = 3

Therefore, the solution to the system is the ordered pair (3, -1).

Answer:

g(x) = (x-3) ^2 -3

Step-by-step explanation:

f(x) = x^2

To shift down 3 units, subtract 3  ( When we move up, we add)

h(x) = x^2 -3

To shift to the right 3 units, replace x with (x-3).  I know it seems backwards, but right is minus and left is plus.

g(x) = (x-3) ^2 -3

Answer:

The 13.2 meters from that point on the ocean floor to the wreck.

Step-by-step explanation:

As given

A ship's sonar finds that the angle of depression to a ship wrack on the bottom of the ocean is 12.5°.

If a point on the ocean floor is 60 meters.

Now by using the trigonometric identity.

[tex]tan\theta = \frac{Perpendicular}{Base}[/tex]

As shown in the figure given below.

Perpendicular = CB

Base = AC = 60 meters

[tex]\theta = 12.5^{\circ}[/tex]

Put in the identity

[tex]tan\ 12.5^{\circ} = \frac{CB}{AC}[/tex]

[tex]tan\ 12.5^{\circ} = \frac{CB}{60}[/tex]

[tex]tan\ 12.5^{\circ} = 0.22[/tex]

[tex]tan\ 12.5^{\circ} = 0.22[/tex]

[tex]0.22= \frac{CB}{60}[/tex]

CB = 60 × 0.22

CB = 13.2 meters

Therefore the 13.2 meters from that point on the ocean floor to the wreck.

The distance from the point on the ocean floor directly below the ship to the shipwreck is approximately 13.3 meters.

We will use the tangent function, which relates the angle of depression to the opposite side (the distance from the point directly below the ship to the shipwreck) and the adjacent side (the depth of the ocean at the point directly below the ship).

Given:

The angle of depression [tex]\theta[/tex] is [tex]12.5^o.[/tex]

The depth of the ocean at the point directly below the ship, h, is 60 meters.

We want to find the distance from the point directly below the ship to the shipwreck, which we will call [tex]d.[/tex]

Using the tangent function :  

[tex]\[ \tan(\theta)[/tex] = [tex][\frac{\text{opposite}}{\text{adjacent}}][/tex]

[tex]\[ \tan(12.5^o) = \frac{d}{60} \][/tex]

To find d, we rearrange the equation:  [tex]\[ d = 60 \times \tan(12.5^o) \][/tex]

Now we calculate the tangent of 12.5 and multiply it by 60:[tex]\[ d = 60 \times \tan(12.5^o) \][/tex]

[tex]\[ d \approx 60 \times 0.22169\][/tex]

[tex]\[ d \approx 13.3014 \][/tex]

Therefore, the distance from the point on the ocean floor directly below the ship to the shipwreck is approximately 13.3 meters.

Final answer:

After applying a 40% discount to the original $62 price of the shoes and adding an 8% sales tax, the total cost of the pair of shoes is $40.18.

Explanation:

The question involves calculating the total price of a pair of shoes after a discount and adding sales tax. To find the discounted price, we take 40% off the original price of $62. To calculate 40% of $62, we multiply 62 by 0.40 (which is 40% as a decimal), giving us $24.80. We subtract this discount from the original price: $62 - $24.80 = $37.20, which is the discounted price of the shoes.

Next, calculate the sales tax on the discounted price by converting the sales tax rate from a percent to a decimal. The sales tax rate is 8%, which as a decimal is 0.08. Multiply the discounted price by the sales tax rate: $37.20 x 0.08 = $2.976, which we round to $2.98.

Finally, add the sales tax to the discounted price to find the total cost: $37.20 + $2.98 = $40.18. Therefore, the total price of the shoes, including tax, is $40.18.

Answer: Third option is correct.

Step-by-step explanation:

Since we have given that

In ΔABC,

∠A= 30°

∠B=75°

We need to find the value of ∠ACD=x

As we know that "Sum of interior angles is equal to exterior angle":

So, we will have,

[tex]\angle A+\angle B=\angle ACD\\\\30\textdegree+75\textdegree=\angle ACD\\\\105\textdegree=\angle ACD[/tex]

Hence, Third option is correct.

Answer:

The answer is 105 degrees

Answer:

Can not be determined.

Step-by-step explanation:

We can easily notice that the limit is x tends to infinity, whereas x is not present in the given function, we are given (1 + 1/n). So we can not evaluate the given limit for x as parameter, we must have some function of x to solve this problem.

Hence, option C is correct i.e. the limit can not be determined.

Answer:

cannot be determined

Step-by-step explanation:

If we have, [tex]\lim_{n \to \infty} {1+\frac{1}{n}}[/tex]

We plug in infinity for n directly

1/∞ =0

So when we plug in infinity for n  then 1/n becomes 0

[tex]\lim_{n \to \infty} {1+\frac{1}{n}}[/tex]

[tex] {1+\frac{1}{infinity}}[/tex]

1+ 0 = 1

In our problem , limit says x-> ∞

there is no x  term inside

[tex]\lim_{x \to \infty} {1+\frac{1}{n}}[/tex]

so we can clearly say limit cannot be determined

Answer:

Volume of a in z = 876 ounces

Step-by-step explanation:

For z, the ratio of x and y is 3 : 11

x : y = 3 : 11 , which means in 14 parts of solution z : x will be 3 parts and y will be 11 parts

So, in 2520 ounces solution of z ,

[tex]x=\frac{2520*3}{14}=540\\y=\frac{2520*11}{14}=1980[/tex]

Volume of a in z = { Volume of a in x + Volume of b in x }

Therefore,

[tex]Volume \thinspace of \thinspace a\thinspace in\thinspace x = 540\cdot \frac{2}{5} = 216\\Volume \thinspace of \thinspace b \thinspace in \thinspace x = 1980\cdot \frac{1}{3}=660[/tex]

So, Volume of a in z = 876 ounces

Answer:

18.91 percent

Step-by-step explanation:

Percent error equation:     Difference       or    Difference/Actual

                                            Actual

The difference is the greater amount minus the smaller.

111 - 89 = 22

The actual is 111.

Now divide 22/111.

22/111 = 0.189 repeating

0.189 repeating = about 18.91 percent

Answer:

The density of the  bar of gold is  19.32 grams per cubic centimeter .

Step-by-step explanation:

Formula

[tex]Density = \frac{Mass}{Volume}[/tex]

As given

A bar of gold has a volume of 722 cubic centimeters and weighs 13.949 kilograms.

As 1 kilogram = 1000 gram

Than convert 13.949 kilograms into grams.

13.949 kilograms = 13.949 × 1000 grams

                             = 13949 grams

Mass = 13949 grams

Volume = 722 cubic centimeter

As put in the formula

[tex]Density = \frac{13949}{722}[/tex]

Density = 19.32 grams per cubic centimeter (Approx)

Therefore the density of the  bar of gold is  19.32 grams per cubic centimeter .
