Find the equation in point-slope form of a line that has a slope of 2 and goes through the point (-5, 3).
Answer:
The answer is
[tex] \huge y - 3 = 2(x + 5)[/tex]
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
From the question we have the final answer as
[tex]y - 3 = 2(x + 5)[/tex]

Answer:
50%, 20%, 36%
Step-by-step explanation:
A: 2012=190, 2014=285. 95 more students. 95 is half of 190.
B: 2014=285, 2015=228. 57 less students. 57 is 20% of 285.
C: 2013=210, 2014=285. 75 more students. 75 is roughly 36% of 210.
Alice solves every puzzle with probability 0.6 , and Bob, with probability 0.5 . They are given 7 puzzles and each chooses 5 out of the 7 puzzles randomly and solves them independently. A puzzle is considered solved if at least one of them solves it. What is the probability that all the 7 puzzles happen to be solved by at least one of them
Answer:
0.021943
Step-by-step explanation:
Alice solves every puzzle with a probability of 0.6
Bob solves every puzzle with a probability of 0.5
Number of puzzles given = 7
The probability of a puzzle been solved by either Alice or Bob
P = P( A U B ) = P( A ) + P( B ) - P( A n B )
= 0.6 + 0.5 - ( 0.6 * 0.5 ) = 0.8
probability of all 7 puzzles solved = (P( A ))^2 * ( P )^3 * (p(B))^2
= ( 0.6 )^2 * (0.8)^3 * (0.5)^2 = 0.04608
Finally determine the P ( choosing 5 out of 7 for both such that all the 7 are chosen )
attached below is the remaining part of the solution
A gym charges each member $100 for a membership fee and $30 per month after that. How much money will a member spend after 6 months
Answer:
280
Step-by-step explanation:
Month 1: 100 + 30 = 150
Month 2: +30
Month 3: +30
Month 4: +30
Month 5: +30
Month 6: +30
Total: 280
Hope this helps!
Answer:
$280
Step-by-step explanation:
For this problem, we simply need to take the initial cost of membership and add that to the reoccurring cost from a time period, in this case, 6 months. So let's make an equation to represent this.
The initial cost is $100
The per month cost is $30
Total cost after 6 months = Inital cost + Per Month Cost * 6 months
Total cost = $100 + $30 * 6
Total cost = $100 + $180
Total cost = $280
Thus, a member will spend $280 after 6 months on the membership.
Cheers.

Find the length of side x in simplest radical form with a rational denominator.
Answer:
[tex] x = \frac{\sqrt{6}}{2} [/tex]
Step-by-step explanation:
Reference angle = 45°
Opposite side = x
Hypotenuse = √3
Use the following trigonometric ratios formula to find x:
[tex] sin(\theta) = \frac{opp}{hyp} [/tex]
Plug in the values
[tex] sin(45) = \frac{x}{\sqrt{3}} [/tex]
Multiply both sides by √3
[tex] \sqrt{3}*sin(45) = x [/tex]
[tex] \sqrt{3}*\frac{\sqrt{2}}{2} = x [/tex]
[tex] \frac{\sqrt{3*2}}{2} = x [/tex]
[tex] \frac{\sqrt{6}}{2} = x [/tex]

A triangle with an area of 10 square meters has a height of 4.5 meters. A similar triangle has an area of 90 square meters. What is the height of the larger triangle?
A) The ratio of the area of the small triangle to the area of the larger triangle is _:_
B) The ratio of the side length of the small triangle to the side length of the larger triangle is _:_
Answer:
h = 40.5 m
A) 1 : 9
B) 1 : 3
Step-by-step explanation:
Let the height of the larger triangle be h
Therefore,
[tex] \frac{10}{90}= \frac{4.5}{h}\\\\
\frac{1}{9}= \frac{4.5}{h}\\\\
h = 9\times 4.5\\\\
h = 40.5\:m\\[/tex]
A)
The ratio of the area of small triangle to the large triangle
[tex] =\frac{10}{90}=\frac{1}{9}=1 : 9[/tex]
B)
The ratio of the side length of small triangle to the side length of large triangle
[tex] =\sqrt{\frac{10}{90}} =\sqrt {\frac{1}{9}} =1 : 3
[/tex]
