Write one parallel equation, to the equation y = 3x + 2 with a y-intercept of 5.
Answer:
[tex]y=3x+5[/tex]
Step-by-step explanation:
Parallel lines have the same slope.
This means that we would only have to change the y-intercept to get our new line.
We are asked to write an equation of a parallel line with the y-intercept of five.
Rewrite the infomation to create the new equation. Note that parrarell lines have the same slope.
[tex]y = 3x + 2\rightarrow\boxed{y=3x+5}[/tex]

Step-by-step explanation:
Milo earns his regular pay of $12.00 per hour for up to
40 hours of work per week. For each hour over
40 hours of work per week, Milo earns 1 times his
regular pay. How much does Milo earn in a week in
which he works 45 hours?
Answer: $540
Step-by-step explanation:
If Milo works 40 hours for the week, he earns $12.00 per hour.
If Milo works anything over $40, he makes 1 times his normal pay which means that he is making the same amount over 40 hours as he is under 40 hours.
If he works 45 hours therefore, his pay is:
= 45 * 12
= $540
Can any one help? Model the pair of situations with exponential functions f and g. Find the approximate value of x that makes f(x) = g(x). f: initial value of 800 decreasing at a rate of 12% g: initial value of 20 increasing at a rate of 12%
Answer:
The given exponential functions f(x) and g(x) will be equal for the value of x as 4.1466.
Step-by-step explanation:
We need to give exponential function to the given constraints.
since f(x) is a decreasing function so
f(x) = [tex]a(1-r)^x[/tex]
where
a = Initial value
r = rate at which function is decreasing
as we are given the values of a and r such as a = 800 and r = 12%
upon substituting these values in the equation we get
f(x) = [tex]800(1-0.12)^x[/tex]
= [tex]800(0.88)^x[/tex]
similarly we will do for g(x) but the only difference in f(x) and g(x) will be that f(x) in a decreasing exponential function whereas g(x) is an increasing function.
g(x) = [tex]a(1-r)^x[/tex]
where a is initial value and r is the rate at which the function is increasing so upon substituting these values we get.
g(x) = [tex]20(1+0.12)^x[/tex] = [tex]20(1.12)^x[/tex]
Now,
we need to find the value of x for which f(x) and g(x) will be equal.
so
[tex]800 (0.88)^x = 20(1.12)^x[/tex]
[tex]40(0.88)^x = (1.12)^x[/tex]
x will be approximately 4.1466
Therefore the given exponential functions f(x) and g(x) will be equal for the value of x as 4.1466.

Show that ( 1 +i )2 = 2i
Given:
The statement is
[tex](1+i)^2=2i[/tex]
To prove:
The given statement [tex](1+i)^2=2i[/tex].
Solution:
We have,
[tex](1+i)^2=2i[/tex]
Taking LHS, we get
[tex]LHS=(1+i)^2[/tex]
[tex]LHS=(1)^2+2(1)(i)+(i)^2[/tex] [tex][\because (a+b)^2=a^2+2ab+b^2][/tex]
[tex]LHS=1+2i+(-1)[/tex] [tex][\because i^2=-1][/tex]
On further simplification, we get
[tex]LHS=1+2i-1[/tex]
[tex]LHS=2i[/tex]
[tex]LHS=RHS[/tex]
Hence proved.

William doubled the amount of money he had after raking leaves. Now he has $24.50. How much money did he hav before he doubled it?
Represent the amount that William had as the quotient of two rational numbers: then, determine how much money William had before he double it.
Answer:
x=8.16
Step-by-step explanation:
x=the money before
2x=doubled
3x=24.50
x=8.16
Answer:
The answer would be...
Step-by-step explanation:
$12.25 Because if you divide $24.50 by 2 then you would get the amount of money William had before he got doubled which would be $12.25.

A new tv costs 1500, a salesperson makes 3.25% commision for every sale, how much would the salesperson make for 1 tv sold.
Answer:
48.75
Step-by-step explanation:
The salesmen makes a commission of 3.25%. So to get the percent into a usable form for this take 3.25 and divided by 100. You get 0.0325.
Now you take the 0.0325 and mutliply it by the 1500. This gives you 48.75

The area of the triangle is
108 m². What is the value
of x?
xm
(x+6) m
Answer:
x = 12
Step-by-step explanation:
Formula for area of a triangke is;
A = ½bh
Where;
b is base
h is height
From the triangle diagram given;
b = x + 6
h = x
Thus;
A = ½(x + 6)x
A = ½x² + 3x
Now we are told that the area is 108 m², Thus;
½x² + 3x = 108
Multiply through by 2 to get;
x² + 6x = 216
x² + 6x - 216 = 0
Using quadratic formula, we arrive at;
x = -18 or 12
x can't be negative, thus; x = 12
A student has heard that spinning pennies on a table, rather than flipping them in the air, results in tails side up 65% of the time. If this is true, what is the probability that a student who spins 4 pennies will have them all land tails side up? 0.0150 0.1785 0.8215 0.9850
so I believe it is C 0.8215
The probability is 0.1785
What is probability?The study of how likely certain events are to occur is known as probability. In its simplest form, it is concerned with the fall of a game's cards or the roll of a dice. However, probability is also essential to life and science as a whole. Probability is used, for example, in weather forecasting and figuring out how much your insurance premiums will cost.
Given probability of tail by spinning a coin is 65% = 0.65
p(t) = 0.65 and p(h) = 0.35
where h= head and t= tail
coin spins 4 time
p(t) for first time = 0.65
p(t) for second time = 0.65 x 0.65 =0.4225
p(t) for third time = 0.65 x0.65 x 0.65 = 0.274
p(t) for fourth time = 0.65 x 0.65 x0.65 x 0.65 = 0.178
Hence probability that a student who spins 4 pennies will have them all land tails is 0.178

If the length of a rectangle is 12cm and the area is 48. What's the breadth and what's the perimeter??
Answer:
1. The breadth is 4 cm
2. The perimeter is 32 cm
Step-by-step explanation:
From the question given above, the following data were obtained:
Length (L) = 12 cm
Area (A) = 48 cm²
1. Determination of the breadth.
Length (L) = 12 cm
Area (A) = 48 cm²
Breadth (B) =?
A = L × B
48 = 12 × B
Divide both side by 12
B = 48 / 12
B = 4 cm
Thus, the breadth is 4 cm.
2. Determination of the perimeter
Length (L) = 12 cm
Breadth (B) = 4 cm
Perimeter (P) =?
P = 2(L + B)
P = 2(12 + 4)
P = 2(16)
P = 32 cm
Thus, the perimeter of the rectangle is 32 cm

For the given coordinate plane the letters A, B, C and D represent the y-axis, first quadrant, origin and x-axis respectively.
What is a coordinate plane?A coordinate plane can be defined as the surface formed by two perpendicular lines which intersect each other. The vertical and horizontal lines are known as y and x axis respectively.
The intersection of these lines is known as the origin.
The diagram of the coordinate plane can be analysed as,
(a) Line A is the vertical perpendicular line.
It can be called as y-axis.
(b) Region B lies in the part of the coordinate plane where x and y coordinates are positive.
It is known as the first quadrant.
