Initially, both salary options provide the same increase, but after two years Option 1 becomes more beneficial due to compounding. After 10 years, the 5% annual increase of Option 1 provides a higher salary than the flat rate increase of Option 2.
Explanation:The salary options present themselves differently over time. Initially, Option 2, the guaranteed increase of $1,000 each year, is more beneficial. In the first year, a 5% increase on a $20,000 salary (Option 1) is only $1,000 - the same as Option 2. However, in the second year, the 5% increase is applied to the new salary of $21,000 (in Option 1), which gives an increase of $1,050 - thus, it surpasses Option 2.
After 10 years, Option 1 will be more beneficial. The reason lies in the principles of compounding; each year, the 5% increase is applied to the increased salary. Thus, in 10 years' time, the amount gained annually in Option 1 significantly surpasses the static $1,000 per year increase of Option 2.

Answer:
∠ A = 68°
Step-by-step explanation:
The sum of the interior angles of a kite = 360°
The opposite angles A and C are congruent
360° - (123 + 101)° = 360° - 224° = 136°
Thus since ∠ A = ∠ C, then
∠ A = [tex]\frac{136}{2}[/tex] = 68°
Please answer ASAP. What is the negative angle of rotation for the angle with positive angle
of rotation 270º?
Answer:
-90
Step-by-step explanation:
The full circle is 360 degrees, so is you turn one way say 10 degrees, then you would need to move 350 degrees in opposite direction.
So, in this case moving 270 one way would be equivalent to moving 360-270=90 degrees in the opposite direction
at the grocery store, you bought 4 boxes of cereal and a carton of strawberries. The carton of strawberries costs $2.89. The bill came to a total of $12.25. How much was one box of cereal?
Answer:
$2.34
Step-by-step explanation:
Cost of 4 boxes
The cost of 4 boxes must be the difference between the total and the strawberries
total-strawberries
12.25-2.89=9.36
4 boxes costs $9.36
Cost of 1 box
You bought 4 boxes for $9.36, and each box costs the same, so we can divide the cost by the number of boxes
cost/boxes
9.36/4=2.34
Each box of cereal costs $2.34
Answer:
$2.34
Step-by-step explanation:
So first you have to subtract 2.89 from 12.25. then you should get 9.36. After you get that you have to divide 9.36 by 4 because there are 4 boxes of cereal and we need to know how much is the cost of one box of cereal. ONce you get that the answer would be $2.34.

Look at the figure. Find the value of x.
A.) 90
B.) 30
C.) 15
D.) 45
Answer:
15
Step-by-step explanation:
An isosceles triangle has equal base angles.
Hence,
[tex] 3x=5x-30\\
\implies 30=2x\\
\implies x=15[/tex]
Answer:
C
Step-by-step explanation:
Well all triangles need to be equal to 180°. When you substitute a, b, and d in for x, the result are bigger than 180 not including the 3rd angle. With C the angles equal 45° and 45° angle which leave the appropriate sized angle for the 3rd angle at 90°. So x is equal to 15.
What is side Bc round to nearest hundredth
Answer:
BC = 15.01
Step-by-step explanation:
Solve this question using a trigonometry ratio, which you can remember them all with SohCahToa, which says:
sinθ = opp / hyp
cosθ = adj / hyp
tanθ = opp / adj
θ means the "angle of reference" (angle we are talking about).
In this problem, θ is A = 65°,
To decide which trig. ratio to use, find out which sides we want to use. We will use AC = 7 because we know it.
We also use BC because we need to find it.
In relation to ∠A or θ, AC is adjacent and BC is opposite.
The ratio with adjacent and opposite is tangent.
tanθ = opp / adj Substitute the variables for this question
tanA = BC / AC Substitute the values you know
tan65° = BC / 7 Rearrange this and isolate C
BC = 7tan65° Multiply 7 and tan65 to find the missing side
BC = 15.011548...... Exact answer on your calculator
BC ≈ 15.01 Round to nearest hundredth

of change of the value of his portfolio?
A) It decreases 78% per year. B) It decreases 22% per year.
C) It increases 78% per year. D) It increases 22% per year.
Answer:
B) It decreases 22% per year.
Step-by-step explanation:
We are given that The value, v(.r), of his portfolio can be modeled with the function : [tex]y(x) = 30,000(0.78)^x[/tex]
Where x is the number of years since he made his investment.
Formula :[tex]P(1-r)^t=A[/tex]
Where P = Principal
r = rate of decrease
t = time
A = Amount after t years
So, On comparing
P = 30000
t=x
A=y(x)
[tex]1-r=0.78[/tex]
[tex]\Rightarrow 1-0.78=r[/tex]
[tex]\Rightarrow 0.22=r[/tex]
So, r = 0.22
r=22%
So, Rate of decrease is 22%
So, Option B is true,
It decreases 22% per year.

Which of the following is not equal to 63.7 mm?
6.37 x 10 4 µm
6.37 x 10 -5 km
637 cm
0.637 dm
The correct option is c. 637 cm is not equal to 63.7 mm.
To solve this problem, we need to convert each of the given units to millimeters (mm) and then compare them to 63.7 mm.
a. [tex]\(6.37 \times 10^4 \, \mu m\)[/tex] to mm:
Since 1 mm = \(1 \times 10^3 \, \mu m\), we have
\[6.37 \times 10^4 \, \mu m \times \frac{1 \, mm}{1 \times 10^3 \, \mu m} = 63.7 \, mm\]
This is equal to 63.7 mm.
b. [tex]\(6.37 \times 10^{-5} \, km\)[/tex] to mm:
Since 1 km = [tex]\(1 \times 10^6 \, mm\)[/tex], we have
[tex]\[6.37 \times 10^{-5} \, km \times \frac{1 \times 10^6 \, mm}{1 \, km} = 63.7 \, mm\][/tex]
This is also equal to 63.7 mm.
c. 637 cm to mm:
Since 1 cm = 10 mm, we have
[tex]\[637 \, cm \times \frac{10 \, mm}{1 \, cm} = 6370 \, mm\][/tex]
This is not equal to 63.7 mm.
d. 0.637 dm to mm:
Since 1 dm = 100 mm, we have
[tex]\[0.637 \, dm \times \frac{100 \, mm}{1 \, dm} = 63.7 \, mm\][/tex]
This is equal to 63.7 mm.
Therefore, the only option that is not equal to 63.7 mm is 637 cm.

A bacterial culture starts with 400 bacteria and grows at a rate proportional to its size. After 2 hours there will be 800 bacteria.
1) Express the population, P(t) after t hours as a function of t
2) Using your equation from above, what will the population be after 8 hours?
3) Using your equation from above, after how many hours will the population reach 2270 bacteria?
Answer:
P(t) = 400×2^(t/2)64005.0Step-by-step explanation:
The wording "a rate proportional to its size" is an indication that growth (or decay) is exponential.
1) For many problems involving exponential growth, I like to use the numbers given in the problem statement as follows.
population = (initial population) × (growth factor)^(t/(growth period))
where the "growth period" is the period of time in which the population is multiplied by the "growth factor".
Here, we're given ...
(initial population) = 400
(growth factor) = 800/400 = 2
(growth period) = 2 . . . . hours
So, our population function can be written as ...
P(t) = 400×2^(t/2)
__
2) Putting t=8 into the formula, we get ...
P(8) = 400×2^(8/2) = 400×16 = 6400
After 8 hours, the population will be 6400.
__
3) Fill in the given number and solve for t.
2270 = 400×2^(t/2)
2270/400 = 2^(t/2)
Taking logs, we have ...
log(227/40) = (t/2)log(2)
t = 2×log(227/40)/log(2) ≈ 5.009
After 5.0 hours, the population will reach 2270.

QR is tangent to circle P at point Q.
Circle P is shown. Line segment P Q is a radius. Line segment Q R is a tangent that intersects the circle at point Q. A line is drawn from point R to point P and goes through a point on the circle. Angle Q P R is 53 degrees.
What is the measure of angle R?
37°
53°
90°
97°
Answer:
A. 37 degrees
Step-by-step explanation:
Since QR is tangent to the circle, it means that is in a right angle. Meaning that angle Q is equal to 90 degrees.
Since you know what two angles are equal to, you can use the triangle angle sum theorem by setting them all up to 180.
53+90+x=180
Simplify the answer
143+x=180
Subtract 143 from both sides
X=37

The measure of angle ∠QRP = 37°.
What is a tangent to a circle ?Tangent to a circle is a straight line which touches the circle at only one point and the point of contact is perpendicular to the radius drawn from the center of the circle.
In the given question
Line segment PQ is radius, Line segment QR is is a tangent to the circle(P) at point Q.
Here QR is perpendicular to PQ because tangent to a circle is perpendicular to the point of contact and a line (PQ) drawn from the center of the circle (P).
∴ ∠PQR = 90° given ∠QPR = 53° We have to find ∠QRP .
We know the sum of all the interior angles in a triangle is = 180°
∠PQR + ∠QPR + ∠QRP = 180°
90° + 53° + ∠QRP = 180°
∠QRP = 180° - (90° + 53°)
∠QRP = 180° - 143°
∠QRP = 37°

We know angle P is 90 degrees because of Thales Theorem, and angle N is 60 degrees. Because the angles in a triangle have to add up to 180 degrees, angle PMN has to be 30 degrees.
Angle QMO is half of angle PMN, so it's 15 degrees. Angle MQO is equal to angle QMO because the radii make Triangle OQM isosceles, so angle MQO is 15 degrees.

simplify 3 square root of 4/ 3 square root of 5
The final simplified expression is 2 over the square root of 5, represented as [tex]\( \frac{2}{\sqrt{5}} \).[/tex]
Let's break it down step by step:
1. Simplify the square roots:
[tex]- \(\sqrt{4}\) equals 2 because \(2 \times 2 = 4\). So, \(\sqrt{4} = 2\).[/tex]
- We have [tex]\(\sqrt{5}\)[/tex] in the denominator, which cannot be simplified further because 5 is a prime number and doesn't have any perfect square factors.
2. Substitute the simplified square roots:
- After simplifying [tex]\(\sqrt{4}\)[/tex] to 2, the expression becomes [tex]\(\frac{3 \times 2}{3\sqrt{5}}\).[/tex]
3. Cancel out the common factor:
- Both the numerator and the denominator have a factor of 3. So, we can cancel out 3 from both sides:
[tex]\[\frac{3 \times 2}{3\sqrt{5}} = \frac{2}{\sqrt{5}}\][/tex]
4. Final simplification:
- The expression [tex]\(\frac{2}{\sqrt{5}}\)[/tex] is simplified as far as it can go because the square root of 5 cannot be simplified further.
So, the simplified expression is [tex]\(\frac{2}{\sqrt{5}}\).[/tex]
