If f(x) = -2[x] + 8, what is f(-1.8) (PLS HELP ASAP)

[tex]519km^{2}[/tex] will be the area after [tex]14[/tex] years.

What is area?

Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

According to questions, a certain forest covers an area of  [tex]1800[/tex] [tex]km^{2}[/tex]. Each year this area decreases by [tex]8.5[/tex]%.

We have to find the area after 14 years.

Area after 14 years can be found using the below formula

[tex]A=I(1-r)^{t}[/tex]

   [tex]=1800(1-0.085)^{14}[/tex]

   [tex]=1800[/tex]×[tex]0.288[/tex]

   [tex]=519km^{2}[/tex]

Hence, [tex]519km^{2}[/tex] will be the area after [tex]14[/tex] years.

The recursive formula an = an – 1 + an – 2 describes a sequence where each term is the sum of the two previous terms. To find the first five or six terms, we substitute the given initial conditions into the formula and repeatedly apply it to find subsequent terms.

The recursive formula an = an – 1 + an – 2 describes a sequence where each term is the sum of the two previous terms. To find the first five terms, we begin with a1 = 1.2 and a2 = 2.3. Then we use the formula to find the next terms:

So the first five terms of the sequence are 1.2, 2.3, 3.5, 5.8, and 9.3.

Similarly, to find the first six terms of the sequence with a3 = -5 and a4 = 3, we use the formula:

So the first six terms of this sequence are -5, 3, -2, 1, -1, and 0.

The correct simplification of the given expression  [tex]tan(-x){\times}cos(-x)[/tex] is [tex]-sinx[/tex].

Step-by-step explanation:

The given expression is:

[tex]tan(-x){\times}cos(-x)[/tex]

Now, simplifying the above given expression, we get

=[tex]\frac{sin(-x)}{cos(-x)}{\times}cos(-x)[/tex] (because [tex]tanx=\frac{sinx}{cosx}}[/tex])

=[tex]sin(-x)[/tex]

Also, we know that [tex]sin({-\theta})=-sin{\theta}[/tex], tehrefore teh expression becomes

=[tex]-sinx[/tex]

Hence, the correct simplification of the given expression  [tex]tan(-x){\times}cos(-x)[/tex] is [tex]-sinx[/tex].

28.7251 =

 28 degrees

 then take the decimal and multiply by 60 to get the minutes

 so 0.7251 *60 = 43.506, use the whole number (43)

 so now you have 28 degrees, 43 minutes

 now take the remaining decimal ( 0.506) and multiply by 60

0.506*60= 30.36

 when you have a decimal left over for the seconds, keep that as is.

 so you now have 28 degrees, 43 minutes and 30.36 seconds

 use ' for minutes and " for seconds

28 degrees 43' 30.36"

rounded to the nearest second would be 28 degrees 43 minutes and 30 seconds

opposite angles = 180

180-49 = 131

 angle 2 = 131 degrees

Final answer:

The number of zeros at the end of 100! is determined by counting the multiples of 5 in the factorization, including higher powers like 25. The result is a total of 24 zeros at the end of 100!.

Explanation:

To determine how many zeros are at the end of the factorial of 100 (100!), we need to know how many times the number 10 can be factored within that number. Since 10 is the product of 2 and 5, we should count the number of 2s and 5s in the prime factorization of 100!. The number of zeros at the end of 100! will equal the smaller of these two counts. However, because there are more 2s than 5s in the prime factorization, we only need to count the number of 5s as every 5 will have a corresponding 2 to form a 10.

For 100!, we count how many multiples of 5 there are within that range, including the multiples of 25 (since 25 includes an extra 5), and possibly higher powers of 5 if applicable. For example, 5 is counted once, 25 is counted twice (as 25 = 5×5), and so on.

Therefore, the number of zeros at the end of 100! equals the sum of the integer division of 100 by 5, plus the integer division of 100 by 25, and so on for any higher powers of 5. However, since 100 < 125, we do not need to consider any higher powers than 25.

We calculate:

100 ÷ 5 = 20,

100 ÷ 25 = 4.

Adding these together (20 + 4), we find that there are 24 zeros at the end of 100!.

Step-by-step explanation:

Using the tangent function of trigonometry, the height of the South Carolina State House is calculated to be approximately 180.2 feet. When rounded, the building stands at an estimated 180 feet tall.

To calculate the height of the South Carolina State House, we can use trigonometry. Given that Issac is standing 174 feet from the base and the angle of elevation to the top of the building is 46°, we can use the tangent function to determine the height of the building. The tangent of an angle in a right triangle is the ratio of the opposite side (the height of the building in this case) to the adjacent side (the distance from Issac to the building).

Using the formula:

tangent (angle) = opposite/adjacent

The equation would be:

tangent (46°) = height of building / 174 feet

Solving for the height of the building:

height of building = 174 feet * tangent (46°)

Using a calculator with the tangent function:

height of building = 174 * 1.035530 (approx value of tangent (46°))

So:

height of building ≈ 180.2 feet

Rounded to the nearest foot, the height of the South Carolina State House is approximately 180 feet.

Step-by-step explanation:

[tex]x^2+ 3x = 25\\ \\ x^2+3x+(\frac{3}{2})^2 = 25 +(\frac{3}{2})^2\\ \\ (x+\frac{3}{2})^2 = 25+\frac{9}{4}\\ \\ (x+\frac{3}{2})^2 =27.25\\ \\ \sqrt{(x+\frac{3}{2})^2} =\pm \sqrt{27.25} \\ \\ x+1.5= \pm \sqrt{27.25} \\ \\ x= -1.5 \pm \sqrt{27.25}\\ \\ x=-1.5+ \sqrt{27.25}=3.72015... \approx 3.72\\ \\ or\\ \\ x=-1.5-\sqrt{27.25} =-6.72015...\approx -6.72[/tex]

So, the solutions are:  [tex]x= 3.72, -6.72[/tex]

Third one will be correct.

Step-by-step explanation:

Given  : y =[tex]log_{8}(x)[/tex].

To find : Graph  and its inverse.

Solution : We have given that

y =[tex]log_{8}(x)[/tex].

For x - intercept , y =0.

y = 0

0 =[tex]log_{8}(x)[/tex].

x = 1

(1,0)

Inverse of  y =[tex]log_{8}(x)[/tex].

Interchange the x and y.

x = [tex]log_{8}(y)[/tex].

Solving for y

y = [tex]8^{x}[/tex].

Then For x = 0

y =  [tex]8^{0}[/tex].

y = 1

For inverse ( 0 ,1)

Then we can see from given graphs Third one will be correct.

Therefore, Third one will be correct.
