Step-by-step explanation:
Lan pays a semiannual premium of $650 for automobile insurance, a monthly premium of $125 for health insurance, and an annual premium of $450 for life insurance.
The monthly expense is $? with explanation
Answer:
Monthly Expense = $270.83
Step-by-step explanation:
The semi-annual premium is paid twice a year so,
Automobile insurance premium for whole year = 650*2
= $1300
Monthly premium will be paid 12 times a year so,
Health insurance premium for whole year = 125*12 = $1500
Annual premium is only paid once a year.
So adding all the premiums will give us the total premiums for whole year.
Total amount of premium for a year = $1300+$1500+$450
= $3250
The premium amount for whole year is $3250. To find the monthly expense, we will divide it by 12.
So monthly expense is:
= 3250/12
= $270.83 ..
To find the monthly expense, calculate the total annual premium for each insurance and divide by 12. The monthly expense is $187.5.
Explanation:To find the monthly expense, we need to calculate the total annual premium for each insurance and divide it by 12 (since there are 12 months in a year).
For automobile insurance, the semiannual premium is $650, so the annual premium is $650 * 2 = $1300.
The monthly premium for health insurance is $125.
For life insurance, the annual premium is $450.
Now, let's calculate the total monthly expense: ($1300 + $125 + $450) / 12 = $187.5.
So, the monthly expense is $187.5.
which statements are true?
Please see picture
Answer:
Following are the statements:
a. logₐb - logₐc = logₐb/logₐc
False.
b. logₐB - logₐc = logₐ(b/c)
True.
c. log₄(5x+16) = log₄5x+log₄16 = 2 +log₄5x
False.
d. log₄(5x*16) = log₄5x+log₄16 = 2 +log₄5x
True.
e. logₐ(3x)₂ = 2 logₐ3 + logₐx
False.
f. logₐ(3x)₂ = 2 logₐ3 + 2 logₐx
Answer:
a. False
b. True
c. False
d. True
e. False
f. True
Step-by-step explanation:
By properties of logarithms:
a. False: ㏒ₐb-㏒ₐc ≠ (㏒ₐb / ㏒ₐc) does not exists that property
b. True: (㏒ₐb)-(㏒ₐc) = ㏒ₐ(b/c) Logarithm of a Quotient
c. False: Does not exists the property: ㏒ₐ(c+b) = ㏒ₐc + ㏒ₐb
so
㏒₄(5x+16) ≠ ㏒₄5x + ㏒₄16 but, ㏒₄16 + ㏒₄5x = 2 + ㏒₄5x
because ㏒₄16 = 2.
d. True: Logarithm of a Product: ㏒ₐ(c×b) = ㏒ₐc + ㏒ₐb
so
㏒₄(16×5x) = ㏒₄16 + ㏒₄5x = 2 + ㏒₄5x
e. False: Logarithm of a Power: ㏒ₐ(c×b)ⁿ = n ㏒ₐ(c×b) = n (㏒ₐc + ㏒ₐb) = n ㏒ₐc + n ㏒ₐb
so
㏒ₐ(3x)² ≠ 2 ㏒ₐ3 + ㏒ₐx
f. Correct use of property in point e.
A 52 year-old father has a son and a daughter. The son is twice as old as the daughter. In 4 years the sum of all their ages will be 100. How old are the two siblings now? (RSM problem)
Answer:The age of daughter is 12 years and age of son is 24 years
Step-by-step explanation:
Given :
Present age of father = 52 years
Let the present age of daughter be x
So according to the question son's age is twice that of daughter's
So present age of son =2x
Now after 4 years the sum of their ages = 100
i.e. x+4 + 2x+4 + 52 +4 =100
3x+ 64 = 100
Subtracting both sides by 64 we get
3x + 64 - 64=100 -64
3x = 36
Dividing LHS and RHS by 3 we get
x=12
i.e. Present age of daughter = x = 12 years
Present age of son = 2x = 2× 12= 24 years
The second angle of a triangular kite is four times as large as the first. The third angle is 55 degrees ° more than the sum of the other two angles. Find the measure of the second angle
Answer:
50 degrees
Step-by-step explanation:
As the kite is triangular, the sum of all angles will be 180 degrees.
Let x be the first angle.
Then according to the statement second angle is four times as large as the first, second angle will be:
4x
And according to the statement, the third angle is 55 degrees ° more than the sum of the other two angles, third angle will be:
x+4x+55
So,
x+4x+x+4x+55=180
10x+55=180
10x= 180-55
10x=125
x=125/10
x=12.5 degrees
So first angle is 12.5 degrees.
Second angle = 4(12.5)
=50 degrees
Third angle = x+4x+55
= 12.5+50+55
= 117.5 degrees
To check if the sum of angles is 180 degrees
= 12.5+117.5+50 = 180
Hence, second angle is 50 degrees ..
Please help!! Local wildlife experts have begun to track the population of trout in their area. The function f represents the approximate population of trout in Sky Lake, and the function g represents the approximate population of trout in Lake Cyan, where t is the number of months since experts began tracking the populations.

g(t) = 0.1t^2 - 4t + 70
Find the expression that describes the total trout population in the area after t months, f(t) + g(t).
A. 0.1t^2 + 5.5t +120
B. 0.1t^2 - 5.5t +120
C. 0.1t^2 - 2.5t + 120
D. 0.1t^2 + 2.5t + 120
Answer:
Option C.
Step-by-step explanation:
We know that
f(t) = 1.5t + 50
represents the approximate population of trout in Sky Lake
And
g(t) = 0.1t^2 - 4t + 70
represents the approximate population of trout in Lake Cyan
The total trout population in the area is described as
f(t) + g(t)
f(t) + g(t) = [1.5t + 50] + [0.1t^2 - 4t + 70]
f(t) + g(t) = [1.5t + 50+ 0.1t^2 - 4t + 70]
f(t) + g(t) = [0.1t^2 -2.5t + 120]
f(t) + g(t) = 0.1t^2 -2.5t + 120

4x -6y =9
Answer:
x = 42/31, y = -37/62
Step-by-step explanation:
5x + 8y =2
4x -6y =9
Multiply the first equation by 4
4(5x + 8y) =2*4
20x +32y = 8
Multiply this equation by -5
-5(4x -6y) =9*-5
-20x +30y = -45
Add them together
20x +32y = 8
-20x +30y = -45
-----------------------------
62y = -37
Divide by 62
62y/62 = -37/62
Multiply the first equation by 3
3(5x + 8y) =2*3
15x +24y =6
And the second equation by 4
4(4x -6y) =9*4
16x -24y = 36
Add them together
15x +24y =6
16x -24y = 36

What is the volume of the cylinder below?
Answer:
[tex]\large\boxed{D.\ 2160\pi\ units^3}[/tex]
Step-by-step explanation:
[tex]\text{The formula of a volume of a cylinder:}\\\\V=\pi r^2H\\\\r-radius\\\H-height\\\\\text{We have}\ r=12\ \text{and}\ H=15.\ \text{Substitute:}\\\\V=\pi(12^2)(15)=\pi(144)(15)=2160\pi[/tex]
The volume of the cylinder is [tex]\( 2160 \pi \)[/tex] units³.
To find the volume of the cylinder, we'll use the formula for the volume of a cylinder, which is given by:
[tex]\[ V = \pi r^2 h \][/tex]
Where:
- V is the volume of the cylinder,
- r is the radius of the cylinder, and
- h is the height of the cylinder.
Given:
- Height h = 15 units
- Radius r = 12 units
We'll substitute these values into the formula:
[tex]\[ V = \pi \times (12)^2 \times 15 \][/tex]
[tex]\[ V = \pi \times 144 \times 15 \][/tex]
[tex]\[ V = 2160 \pi \][/tex]
So, the volume of the cylinder is [tex]\( 2160 \pi \)[/tex] cubic units.
The correct answer is option D: [tex]\( 2160 \pi \)[/tex] units³.

Parallel lines have the same slope.
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points A(-3, 0) and B(-6, 5). Substitute:
[tex]m=\dfrac{5-0}{-6-(-3)}=\dfrac{5}{-3}=-\dfrac{5}{3}[/tex]
The line passes through the origin, therefore the y-intercept is equal to 0.
Therefore we have the equation:
[tex]y=-\dfrac{5}{3}x[/tex]
Convert to the standard form [tex]Ax+By=C[/tex]
[tex]y=-\dfrac{5}{3}x[/tex] multiply both sides by 3
[tex]3y=-5x[/tex] add 5x to both sides
[tex]5x+3y=0[/tex]
The equation of the line parallel to AB passing through the origin is 5x - 3y = 0.
The equation of the line that passes through the origin and is parallel to AB is 5x - 3y = 0.
To find the equation of a line parallel to AB passing through the origin, we first need to find the slope of AB, which is (5 - 0) / (-6 + 3) = 5 / -3 = -5/3.
Since the line passing through the origin and parallel to AB has the same slope, its equation will be of the form y = mx. Substituting the point (0, 0) into y = -5/3x gives us y = -5/3x, which simplifies to 5x - 3y = 0.

Let
[tex]P(n):\ 1+2+\ldots+n = \dfrac{n(n+1)}{2}[/tex]
In order to prove this by induction, we first need to prove the base case, i.e. prove that P(1) is true:
[tex]P(1):\ 1 = \dfrac{1\cdot 2}{2}=1[/tex]
So, the base case is ok. Now, we need to assume [tex]P(n)[/tex] and prove [tex]P(n+1)[/tex].
[tex]P(n+1)[/tex] states that
[tex]P(n+1):\ 1+2+\ldots+n+(n+1) = \dfrac{(n+1)(n+2)}{2}=\dfrac{n^2+3n+2}{2}[/tex]
Since we're assuming [tex]P(n)[/tex], we can substitute the sum of the first n terms with their expression:
[tex]\underbrace{1+2+\ldots+n}_{P(n)}+n+1 = \dfrac{n(n+1)}{2}+n+1=\dfrac{n(n+1)+2n+2}{2}=\dfrac{n^2+3n+2}{2}[/tex]
Which terminates the proof, since we showed that
[tex]P(n+1):\ 1+2+\ldots+n+(n+1) =\dfrac{n^2+3n+2}{2}[/tex]
