She stands 90 meters away from the dam and records the angle of elevation to the top of the dam to be 26º. Scarlett's height is 1.65 meters, so the height of the dam is Make a drawing with a right triangle. The opposite side, y, is the height of the dam less 1.65 m The base or adjacent side is 90 m The angle between the two sides is 90 m. Then tan (26) = y / 90 y = 90 tan(26) = 90 (0.4877) = 43.90 m The height of the dam is 43.90m + 1.65m = 45.55 m Posted in Mathematics For f(x)=2x+1 and g(x)=x^2-7, find (f-g)(x) I hope this helps you (f-g)(x)=2x+1-(x^2-7) (f-g)(x)=2x+1-x^2+7 (f-g)(x)= -x^2+2x+8 Posted in Mathematics 1.

(1, 1.5), (-1, -1.5), (2, 2.5), (-2, 2.5) Based on the given set of ordered pairs above, the set of ordered pairs in the form of (x,y) that does not represent a function of x would be option B. Why is this so? if you notice, the number 1 in the x is being repeated so this means this is not a function. Hope this answer helps.

A certain forest covers an area of 2,000 square kilometers. Suppose that each year this area decreases by 6%. What is the function that best represents the area of the forest each year and how much area remains after 12 years? Round your answer to the nearest square kilometer. Hint: Use the formula, f(x) = P(1 + r)x

For the answer to the question above, I think the formula you is wrong. The x must be in exponential form. It must look like this

f(x) = P(1 + r)^x
Now we can solve.

Given:
P = 2000
r = -0.06

f(x)  =  2000 (1 - 0.06)^x
=  2000 (0.94)^x

2000 (0.94)¹² =

2000 (0.476)  =
951.8 square kilometers.

Posted in Mathematics What is the range of the function f(x) = 3x2 + 6x – 9 I have a solution here however with a slight change in the equation: f(x)=3x^2-6x+1 My solution is: The domain is all real numbers--there are no restrictions like a square root or variable in the denominator this is a U shape parabola and you want to find the bottom point, it is at the vertex x=-b/2a =- (-6) /2 (3) =1 f(1) =3(1)^2 -6(1) +1 =3-6+1 =-2 the minimum is (1, -2) so the range is all real numbers >= -2 By examining my solution, you could just answer the problem on your own! I hope it helps! Posted in Mathematics Find the multiplicative inverse of 6 + 2i. The solution to the problem is as follows: First thing to do is get rid of the i. Multiplying by 6 - 2i will do this ( 6 + 2i)(6 - 2i) = 6^2 - (2i)^2 = 36 - 4(-1) = 36 + 4 = 40 Dividing by 40 gets you 1 (6 + 2i) (6-2i)/40 = 1 The answer is (6 - 2i)/40 = (3 - i)/20 I hope my answer has come to your help.

Posted in Mathematics The price of a cup of coffee was$2.65 yesterday. today, the price fell to $2.50 . find the percentage decrease. round your answer to the nearest tenth of a percent. We must find the difference between prices.$2.65 - $2.50 =$0.15. Now we need to calculate what percent $0.15 is of$2.65. It is 5.7%! The price decreased, so it is a 5.7% decrease!

Sophia is saving money for a new bicycle. The bicycle will cost at least $623. Sophia makes$8.22 per hour. Which inequality could be used find the number of hours Sophia needs to work to make enough money to buy a new bicycle? $8.22h >$623 $8.22h ≤$623 $8.22h ≥$623 $8.22h <$623

C. $623 Step-by-step explanation: We are given that Sophia is saving money for a new bicycle. The bicycle will cost atleast$623.

Sophia makes $8.22 per hour. We have to find the inequality that could be used to find the number of hours Sophia needs to work to make enough money to buy a new bicycle. Let Sophia works h hours to make enough money to buy a new bicycle. Sophia makes money per hour =$8.22

Total money made by Sophia in h hours = According to question $623 Hence, option C is true.

Which function is the inverse of f(x) = 2x + 3? f-1(x) = –2x + 3 f-1(x) = 2x + 3

Let f(x)=y

⇒ x= f(x)=2x+3=y

⇒ 2x+3=y

⇒ 2x=y-3

⇒ x=(y-3)/2 Replacing y by x Hence, inverse of the function f(x)=2x+3 is:
