The value of a car after 10 years be $20898.27 if the car rental company assumes each car in their fleet depreciates by 6% per year option (a) $20898.27 is correct.
What is an exponential function?It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent [tex]\rm y = a^x[/tex]
where a is a constant and a>1
We can solve this problem by exponential function:
The word depreciate means the price is decreasing.
We can find the value be when the car is 10 years old:
p = 38800(1 - 0.06)¹⁰
p = 38800(0.94)¹⁰
p = 20898.266 ≈ $20898.27
Thus, the value of a car after 10 years be $20898.27 if the car rental company assumes each car in their fleet depreciates by 6% per year option (a) $20898.27 is correct.

Iman has 48 months to save $18,000, the maximum amount he estimates his first year of college will cost. he does not want to depend on interest, and does not consider interest when determining his minimum monthly savings goal. what is the minimum amount he should save per month to achieve his goal? $350.00 $375.00 $425.00 $450.00
Answer:
$ 375 / month
Step-by-step explanation:
$ 18 000 / 48 months = 375 /month
The minimum amount he should save per month to achieve his goal is $375.00. Thus, option 2 is correct.
Given that:
Number of months = 48
Monthly savings = $18,000
The minimum amount to save per month can be calculated by dividing the total amount by the number of months:
Minimum monthly savings goal = Total amount to save / Number of months
Minimum monthly savings goal = $18,000 / 48
Minimum monthly savings goal ≈ $375.00
Therefore, the minimum amount he should save per month to achieve his goal is $375.00. Thus, option 2 is correct.

write the ratio for tan A
Answer:
tan A = 5/12
Step-by-step explanation:
The tangent ratio is equal to the length of the side opposite of the angle over the length of the side adjacent to the angle. If we are finding tangent in respect to angle A, the opposite side would be line CB with a length of 5. The adjacent side is line AC with a length of 12. Therefore, the tan A ratio is 5/12.

[100 POINTS] Find the values of x, y, and z.
x 's measure is already given
x=20°
y=x+zy=160+20y=180°Answer:
∡x = 20°
∡y = 160°
∠z = 160°
Step-by-step explanation:
Angles on a straight line sum to 180°
⇒ ∠z + 20° = 180°
⇒ ∠z = 180° - 20°
⇒ ∠z = 160°
The central angle measure equals the corresponding arc measure.
⇒ ∡x = 20°
⇒ ∡y = ∠z = 160°
Find the measure of angle A.
66°
x +49
x+83
Step-by-step explanation:
Since , internal sum of angle of triangle is 180°
So,
66 + x +49 + x+83 = 180
or, 198 + 2x = 180
or, 2x = 180 -198
or, 2x = -18
hence, x = - 9
Now angle A = x + 49
= (-9) + 49
= 40
Hence measure of angle A is 40°.
Answer:
40
Step-by-step explanation:
From triangle law ,
66 + x +49 + x+83 = 180
or, 198 + 2x = 180
or, 2x = 180 -198
or, 2x = -18
hence, x = - 9
Now angle A = x + 49
= (-9) + 49
= 40
Hence, answer is 40.
Two angles of a triangle are in the ratio of 2:3 if the third angle is 50 degree find the other two angles
Answer:
52° & 78°Step-by-step explanation
Two angles of a triangle are in the ratio of 2:3 if the third angle is 50 degree find the other two angles
the sum of the interior angles in a triangle is 180°
so
180 - 50 = 130°
130 : 5 = 26° (unit)
26 * 2 = 52°
26 * 3 = 78°

suppose a normal distribution has a mean of 38 and a standard deviation of 2 what is the probability that a data value is between 37 and 41? round your answer to the nearest tenth of a percent
Using the normal distribution, it is found that there is a 62.4% probability that a data value is between 37 and 41.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, the mean and the standard deviation are given, respectively, by:
[tex]\mu = 38, \sigma = 2[/tex]
As a proportion, the probability that a data value is between 37 and 41 is the p-value of Z when X = 41 subtracted by the p-value of Z when X = 37, hence:
X = 41:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{41 - 38}{2}[/tex]
Z = 1.5
Z = 1.5 has a p-value of 0.933.
X = 37:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{37 - 38}{2}[/tex]
Z = -0.5
Z = -0.5 has a p-value of 0.309.
0.933 - 0.309 = 0.624,
0.624 = 62.4% probability that a data value is between 37 and 41.

The x-intercepts of f(x) are common to those of g(x) .
The x-intercepts of f(x) are common to those of g(x) .
What is x-intercept?
The x-intercept is the point on the coordinate at which a line, curve or plane intersect with the x-axis. The value of y is equal to zero at x-intercept.
For me, it helps to graph everything on the same xy coordinate system. Start with the given graph and plot the points shown in the table. You'll get what you see in the diagram below.
The blue point C in that diagram is on the red parabola. This point is the x intercept as this is where both graphs cross the x axis. Therefore, they have a common x intercept.
Choice 1 is not true due to choice 4 being true. We have f(x) = g(x) when x = 2, which is why f(x) > g(x) is not true for all x.
Choice 2 is not true. Point B is not on the parabola.
Choice 3 is not true. There is only one known intersection point between f(x) and g(x), and that is at the x intercept mentioned above. Of course there may be more intersections, but we don't have enough info to determine this.

A conveyor belt carries supplies from the first floor to the second floor, which is 39 feet higher.
The belt makes a 60° angle with the ground. How far do the supplies travel from one end of
the conveyor belt to the other to the nearest foot? If the belt moves at 70 ft./min., how long
does it take the supplies to move to the second floor to the nearest tenth of a minute?
O 68 ft.; 1.0 min.
O55 ft.; 0.8 min.
O 45 ft.; 0.6 min.
O23 ft.; 0.3 min.
The supplies travelled 45ft and it took 0.6min to get to the next floor.
What is trigonometry?Trigonometry is the branch of mathematics dealing with the relationship between the sides of a triangle and the angles.
Analysis:
The supplies distance travelled, distance of first floor from second floor and the ground form a right angled triangle.
so that sin 60 = 39/distance travelled by supplies
distance travelled by supplies = 39/sin 60 = 39/0.866 = 45 feet.
speed = distance / time
time = distance / speed = 45/70 = 0.6 min
In conclusion, the distance and time time taken for the supplies to get to the next floor is 45feet and 0.6 min respectively.

The factored form of x³ + x² + x + 1 is (x²+1)(x+1).
