Brock Lesnar is standing next to his time machiner when he spots a pterodactyl soaring through the air. Brock Lesnar wants that pterodactyl for his trophy room. So he sets up his range finder and finds that the direct distance from the gun to the pterodactyl is 1000 yds. His angle of elevation to the pterodactyl is 17 degrees if Brock Lesnar his the pterodactyl. How far will he have to drag the dead pterodactyl along the ground to get it back to this time machine.
a. 1046 yds
b. 306 yds
c. 956 yds
d. 400 yds
e. 292 yds
Answer:
C. 956 ydsStep-by-step explanation:
Use cosine to solve this:
cos 17° = x / 1000x = 1000 cos 17°x = 956 ydsCorrect choice is C
Step-by-step explanation:
➡cos17=x/1000
using cross multiplication➡x=1000×cos17
➡x=956yards

Answer: 3 is in the domain of f(g(x)). Step-by-step explanation: ... What is the domain of the given function? a) {x | x = –6, –1, 0, 3}; {y | y = –7, –2, ...
The domain is all real numbers except 9 (positive)
This is because we can't have 0 in the denominator, and when x equals 9, then the denominator is 0. Anything divided by 0 is undefined, which is why 9 (in this equation) is not included.
Answer:
5 is not in the domain of fog
Step-by-step explanation: [tex]g(f(x) = g(\sqrt{x+3} ) = -7(\sqrt{x+3}) +7[/tex] find the domain of [tex]-7(\sqrt{x+3}) +7[/tex] which is [tex]{x|x\geq -3[/tex] therefore any number greater than or equal do -3 are not in the domain. So 5 is not in the domain of fog

Answer:
30
Step-by-step explanation:
Answer:
About -4.286
Step-by-step explanation:
First, let's set up the equation.
(24 + 6)/(3 - 2 [4 + 1])
Now, let us do the parenthesis first. (4 + 1). While we are at it, we can also do 24 + 6.
30/(3 - 2[5)]
Now, -2(5)
30/3 - 10
Let us do 3 - 10
30/-7
Lastly, 30/-7, which unfortunately, is a non-terminating decimal, which is about:
-4.286, rounded to the nearest thousandth.

A woman decides to have children until she has her first girl or until she has five children; whichever happens first. Find the expected value and standard deviation of X. Let X represent the number of children she has. Assume that she is equally likely to give birth to a boy or a girl on each child, and that gender is independent between children.
(a) Write out and sketch the complete probability distribution function for X.
(b) Write out and sketch the complete cumulative distribution function for X.
(c) Find the expected value and standard deviation of X.
Answer:
E(X) = 1.9375
SD(X) = 1.20
Step-by-step explanation:
Let :
G = girl ; B = Boy
P(G) = 0.5 ; P(B) = 0.5
Sample space :
G, BG, BBG, BBBG, BBBBG, BBBBB
Using the multiplication rule of independence :
P(G) = 0.5
P(BG) = 0.5 * 0.5 = 0.25
P(BBG) = 0.5 * 0.5 * 0.5 = 0.125
P(BBBG) = 0.5 * 0.5 * 0.5 * 0.5 = 0.0625
P(BBBBG) = 0.5 * 0.5 * 0.5 * 0.5 * 0.5 = 0.03125
P(BBBBB) = 0.5 * 0.5 * 0.5 * 0.5 * 0.5 = 0.03125
Creating a probability distribution table :
X = 1, 2, 3, 4, 5
For X = 5 ;
P(BBBBG) + P(BBBBB) = 0.03125 + 0.03125 = 0.0625
X :___ 1 ____ 2 ____ 3 _____ 4 _____ 5
P(X) : 0.5 __ 0.25 _ 0.125 _0.0625 _0.0625
The expected value E(X) :
√(ΣX * P(X)) = (1*0.5)+(2*0.25)+(3*0.125)+(4*0.0625)+(5*0.0625) = 1.9375
The standard deviation SD(x) :
√(ΣX²*p(x) - E(X)²
√((1^2*0.5)+(2^2*0.25)+(3^2*0.125)+(4^2*0.0625)+(5^2*0.0625) - 1.9375^2)
√(5.1875 - 3.75390625)
√1.43359375
SD(X) = 1.197
SD(X) = 1.20

A computer game was originally priced at $59.99. It was marked down 15%. Then it was moved to a clearance rack marked "Take an additional 50% off the lowest marked price." What was the final price of the computer game?
Answer:
25.50 is the final price
Step-by-step explanation:
First find the new price at 15% off
59.99 * 15%
59.99 * .15
9.00
Subtract 9 dollars from the price
59.99-9.00
50.99
Now take 50% off
50.99 * 50%
50.99*.50
25.50
50.99-25.50
25.50

Which is the better definition of line of best fit?
A line of best fit guides a line through a scatter plot of data points that best describes the association between those points.
What is line of best fit?
A line of best fit guides a line through a scatter plot of data points that best describes the association between those points. Statisticians typically utilize the least squares approach to arrive at the geometric equation for the line, either through manual computations or regression analysis software.
A line of best fit can be approximately specified utilizing an eyeball the method by marking a straight line on a scatter plot so that the numeral of points above the line and below the line stands about equal (and the line passes via as many points as possible).

23) When a two digits number is divided by the sum of its digits, then the
quotient is 8 and the remainder is 2. If the digits are reversed and the
resulting number so formed is divided by the sum of the digits, the
quotient is 2 and the remainder is 8. Find the two digits number.
Answer: 82
Step-by-step explanation:
As we know remainder formula:-
Dividend = Quotient × Divisor + Remainder
Here, dividend = Two digits number & divisor = Sum of digits
m + 10n = 8 × (m + n) + 2
m + 10n = 8m + 8n + 2
m - 8m + 10n - 8n = 2
2n - 7m = 2
2n = 7m + 2
n = (7m + 2)/2 - - (Eq.1)
Digits interchanged, two digits number is divided by sum of digits, quotient is 2 & remainder is 8.
Now, when digits interchanged:-
Two digits number = 10m + n
Using same formula we get:-
10m + n = 2 × (m + n) + 8
10m + n = 2m + 2n + 8
10m - 2m + n - 2n = 8
8m - n = 8
8m = n + 8
n = 8m - 8 - - - (Eq.2)
Comparing both equations:-
(7m + 2)/2 = 8m - 8
7m + 2 = 2(8m - 8)
7m + 2 = 16m - 16
7m - 16m = -16 - 2
-9m = -18
m = -18/-9
m = 2
So, digit at unit's place = 2
Put this value in (Eq.2)
n = 8(2) - 8
n = 16 - 8
n = 8
So, digit at ten's place = 8
Now two digit number:-
Two digit number = 2 + 10(8)
Two digit number = 2 + 80
Two digit number = 82
