Luke’s has seven coins. He can make 11p with two of his coins. He can make 11p with three of his coins. He can make 11p with four of his coins. What are the seven coin that Luke’s has?
Answers
Answer:
1p 2p 2p 2p 5p 5p 10p
Step-by-step explanation:
Available coins that are less than 11p: 1p 2p 5p 10p
11p with two coins ⇒ 1p + 10p only
11p with three coins ⇒ 1p + 5p + 5p only
11p with three coins ⇒ 2p + 2p + 2p + 5p only
Therefore, the seven coins that Luke has are:
1p 2p 2p 2p 5p 5p 10p

How do you find the mean (average) of a data set?
Answers
Answer:
To find the mean, you must add up all of the numbers in the data set and then divide them by the amount of numbers there are.
Step-by-step explanation:
For example:
1, 2, 3, 4, 5
To find the mean, we first add up all of these numbers:
1 + 2 + 3 + 4 + 5 = 15
Next, since there are 5 total numbers here, we divide their sum by 5:
15/5 = 3
That is how we get the mean (or average) of the data set.

Answers
Problem 9 (#16)
In order to figure out when the amount of sunlight becomes 12 hours for the first time, we need to have [tex]S(t)=12[/tex] and solve the function for [tex]t[/tex]:
[tex]\displaystyle S(t)=12+2\sin\biggr(\frac{2\pi}{365}t\biggr)\\\\12=12+2\sin\biggr(\frac{2\pi}{365}t\biggr)\\\\0=2\sin\biggr(\frac{2\pi}{365}t\biggr)\\ \\0=\sin\biggr(\frac{2\pi}{365}t\biggr)\\\\\pi=\frac{2\pi}{365}t\\\\365\pi=2\pi t\\\\\frac{365}{2}=t[/tex]
Thus, B is the correct answer
Problem 10 (#17)
Recall the half-angle identity [tex]\displaystyle \tan\frac{x}{2}=\frac{1-\cos x}{\sin x}=\frac{\sin x}{1+\cos x}[/tex]Hence, [tex]\displaystyle \cot\frac{1}{2}x=\frac{1}{\tan\frac{1}{2}x }=\frac{\sin x}{1-\cos x}=\frac{1+\cos x}{\sin x}[/tex]So, you could techincally say that the first two options work as each function has their respective identities true for each option.
Thus, I and II is the correct answer
Problem 11 (#18)
[tex]f(\theta)=g(\theta)\\\\4\sin\theta+1=\cos2\theta\\\\4\sin\theta+1=1-2\sin^2x\\\\2\sin^2\theta+4\sin\theta=0\\\\2\sin\theta\bigr(\sin\theta+2)=0[/tex]
[tex]\displaystyle 2\sin\theta=0\\\\\sin\theta=0\\\\\theta=\{0,\pi\}[/tex]
[tex]\sin\theta+2=0\\\\\sin\theta=-2[/tex]
The solution is indeterminate since -2 does not fall in the range of [tex][-1,1][/tex].
Thus, A is the correct answer
Problem 12 (#19)
Recall that the period of a tangent function [tex]y=a\tan(bx-c)+d[/tex] is [tex]\frac{\pi}{|b|}[/tex]. Hence, if [tex]b=2[/tex], then the period of the tangent function is [tex]\frac{\pi}{2}[/tex]. Since I can't see the graphs, you need to identify which graph has a period of [tex]\frac{\pi}{2}[/tex] (meaning the distance between two vertical asymptotes is pi/2), or post this problem again with the graphs.

Answer:

Step-by-step explanation:
This is a problem which can be solved with the pythagoras therom.
[tex]a^{2} +b^{2} =c^{2}[/tex]
Plus we can split this triangle into two triangles.
The split triangle has dimensions of 13(bc) by 5 cm(dc).[tex]a^{2} +b^{2} =c^{2}[/tex]
[tex]5^{2} +b^{2} =13^{2}[/tex]
Now we solve for b which is the lenght of bd
[tex]25 +b^{2} =169[/tex]
[tex]b^{2} =144[/tex]
[tex]b = \sqrt{144}[/tex]
[tex]b = 12[/tex]
Therefore the lenght of bd is 12cm
Hope this helps! :)
To start, you can see that this is a large triangle divided in half to create 2 right triangles. This means we can use the Pythagorean theorem (a^2) + (b^2) = (c^2) to find the segment bd.
To use the theorem we must know at least 2 values of the sides of the triangle. Since segment ac = 10 cm, we can divide this by 2 to get the base values of the smaller triangles, which would be 5 cm.
So a = 5 cm, c = 13 cm
Now, we have what we need and we can plug it in to the equation:
(5 cm)^2 + b^2 = (13 cm)^2
25 cm + b^2 = 169
b^2 = 144
b = 12 cm
