Find the specified value for the arithmetic sequences with the given characteristics. a17 = 47 d = -3 a35= ?
ANSWER
The 35th term is -8
EXPLANATION
The nth term of an arithmetic sequence is given by
[tex]a_n = a_1 + d( n - 1)[/tex]
We have the 17th term to be;
[tex]a_{17}=47[/tex]
and the common difference is d=-3
We substitute to get:
[tex]47= a_1 + - 3(1 7- 1)[/tex]
[tex]47= a_1 + 16( - 3)[/tex]
[tex]47= a_1 - 48[/tex]
[tex]a_1 = 48 + 47 = 95[/tex]
We can now find the 35th term:
[tex]a_{35}=a_{1} + 34d[/tex]
[tex]a_{35}=95 + 34( - 3) = - 8[/tex]

Find the probability of a student being 34 years old or younger. Express your answer as a percent
Answer:
79%
Step-by-step explanation:
The probability that the percent of 18 to 34-year-olds who check social media before getting out of bed in the morning is, at most, 32 is 0.7881 = 78.81%
When the distribution is normal, we use the z-score formula.
What is the z-score formula?
In a set with mean [tex]\mu[/tex]and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z=\frac{X-\mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean.
After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score.
This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.
Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
In this question:
[tex]\mu=28,\sigma=5[/tex]
Find the probability that the percent of 18 to 34-year-olds who check social media before getting out of bed in the morning is, at most, 32.
This is the p-value of Z when X = 32. So
[tex]Z=\frac{X-\mu}{\sigma}[/tex]
[tex]Z=\frac{32-28}{5}[/tex]
[tex]Z=0.8[/tex]
Z=0.8 has a p-value of 0.7881
0.7881 = 78.81% probability that the percent of 18 to 34-year-olds who check social media before getting out of bed in the morning is, at most, 32.

Given: m∠EYL=72° Find: m EHL , m LVE .
Answer:
m(ARC)EHL: 108°
m(ARC)LVE: 252°
Step-by-step explanation:
Hey, so initially, we should start off with some stuff:
The sum of the arcs add up to 360°
m∠EYL=72°
We can create a system and use substitution to find the measure of an arc we don't know.
Step 1: We can use the 'Secants exterior angle theorem' to help us find the measure of (ARC)EHL.
<EYL=1/2((ARC)EVL-[ARC]EHL) (the theorem)
Step 2: By using substitution, we can say that (ARC)EVL=360°-(ARC)EHL
Thus, when we substitute it back into the theorem, the answer will be <EYL=1/2((360°-(ARC)EHL)-(ARC)EHL)=72°
Step 3: When we solve this out (and you can replace (ARC)EHL with x when solving), you will get an answer of x=108° or (ARC)EHL=108°.
Step 4: (ARC)LVE will be equal to 360°-m(ARC)EHL, which, when we substitute, will be 360°-108°, which will come out to be 252°.
Therefore, by algebra, substitution, and part-whole-postulate, (ARC) LVE=252°.

Answer:
320 cubic cm
Step-by-step explanation:
To answer a prism volume question, also see it as a shape (in this case a triangle) that is very thick.
First step is to calculate the area of the shape. We all know the formula to calculate the area of a triangle: (b x h)/2. And we those two measures. The height of the triangle is b (8 cm), the base of the triangle is a (10 cm).
A = (b * h)/2 = (10 * 8) / 2 = 80 / 2 = 40 sq cm
Then we multiply the base area of the prism by its height to get the total volume. In this case, the height is also known, h = 8 cm.
V = b * h = 40 * 8 = 320 cubic cm
Answer:
320
Step-by-step explanation:
The volume of a prism is the height times the area of the base.
V = hA
The base is a triangle. The volume of a triangle is half the base times height.
V = h (½ ab)
Given a = 10, b = 8, and h = 8:
V = ½ (8) (10) (8)
V = 320

Transform each polar equation to an equation in rectangular coordinates and identify its shape.
(a) r=6
(b) r= 2 cos theta
please show ur work
Answer:
(a) [tex]x ^ 2 + y ^ 2 = 6 ^ 2[/tex]
(b) [tex](x-1) ^ 2 + y ^ 2 = 1[/tex]
Step-by-step explanation:
Remember that to convert from polar to rectangular coordinates you must use the relationship:
[tex]x = rcos(\theta)[/tex]
[tex]y = rsin(\theta)[/tex]
[tex]x ^ 2 + y ^ 2 = r ^ 2[/tex]
In this case we have the following equations in polar coordinates.
(a) [tex]r = 6[/tex].
Note that in this equation the radius is constant, it does not depend on [tex]\theta[/tex].
As [tex]r ^ 2 = x ^ 2 + y ^ 2[/tex]
Then we replace the value of the radius in the equation and we have to::
[tex]x ^ 2 + y ^ 2 = 6 ^ 2[/tex]
Then [tex]r = 6[/tex] in rectangular coordinates is a circle centered on the point (0,0) and with a constant radius [tex]r = 6[/tex].
(b) [tex]r = 2cos(\theta)[/tex]
The radius is not constant, the radius depends on [tex]\theta[/tex].
To convert this equation to rectangular coordinates we write
[tex]r = 2cos(\theta)[/tex] Multiply both sides of the equality by r.
[tex]r ^ 2 = 2 *rcos(\theta)[/tex] remember that [tex]x = rcos(\theta)[/tex], then:
[tex]r ^ 2 = 2x[/tex] remember that [tex]x ^ 2 + y ^ 2 = r ^ 2[/tex], then:
[tex]x ^ 2 + y ^ 2 = 2x[/tex] Simplify the expression.
[tex]x ^ 2 -2x + y ^ 2 = 0[/tex] Complete the square.
[tex]x ^ 2 -2x + 1 + y ^ 2 = 1[/tex]
[tex](x-1) ^ 2 + y ^ 2 = 1[/tex] It is a circle centered on the point (1, 0) and with radio [tex]r=1[/tex]

with the current weather conditions a sailboat can sail 5 1/2 miles in an hour.How far can a sailboat sail in 2/3 hours
Answer:
3 2/3 miles
Step-by-step explanation:
distance = rate times time.
Here,
distance = (5.5 mph)(2/3 hr) = 3 2/3 miles
The sailboat can travel 3 2/3 miles in 2/3 hours by multiplying the speed (5 1/2 miles per hour) by the time (2/3 hours) to get the distance.
To determine how far a sailboat can sail in 2/3 hours when it can sail 5 1/2 miles in one hour, we need to perform a multiplication of the speed by the time. The speed of the sailboat is 5 1/2 miles per hour (which is the same as 11/2 miles per hour in improper fraction form), and the time is 2/3 hours.
Here are the steps to calculate the distance:
Convert 5 1/2 miles to an improper fraction: 5 1/2 = (5 times 2 + 1)/2 = 11/2.
Multiply the speed by the time: (11/2) times (2/3) = (11 times 2)/(2 times 3) = 22/6.
Simplify the fraction: 22/6 = 11/3 = 3 2/3 miles.
Therefore, the sailboat can travel 3 2/3 miles in 2/3 hours.

A traffic camera sits on top of a tower that has a height of 50ft., the angles of depression of two cars on a straight road at the same level as that of the base of the tower and on the same side of it are 25° and 40°. Calculate the distance between two cars
Answer:
[tex]\boxed{\text{48 ft}}[/tex]
Step-by-step explanation:
The angle of depression from the camera at D and the angle of elevation from the target cars are congruent.
1. Distance of car A from tower
Consider ∆ACD
tan25 = 50/AC
AC = 50/tan25 = 50/0.4663 = 107.2 ft
2. Distance of car B from tower
Consider ∆BCD
tan40 = 50/BC
AC = 50/tan40 = 50/0.8391 = 59.6 ft
3. Distance from cars A and B
AB = AC – BC = 107.2 – 59.6 = 48 ft
The distance between the two cars is [tex]\boxed{\textbf{48 ft}}[/tex].

How to determine the transformation (mapping) rule?In Mathematics, a translation is a type of transformation that shifts every point of a geometric object in the same direction on the cartesian coordinate, and for the same distance.
Based on the information provided in the diagram, we have the following:
(x, y) → (x + h, y + k)
(0, 0) → (-2, 0).
-2 = x + h
-2 = 0 + h
h = 0 - 2
h = -2 (2 units left)
0 = y + k
0 = 0 + k
k = 0.
In conclusion, a horizontal translation of 2 units to the left would map the parent cubic function f(x) to the transformed cubic function g(x);
g(x) = f(x + 2)
[tex]g(x)=\sqrt[3]{x+2}[/tex]

2(x + 4)(x - 3)
Step-by-step explanation:
Given
2x² + 2x - 24 ← factor out 2 from each term
= 2(x² + x - 12)
To factor the quadratic
Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (+ 1)
The factors are + 4 and - 3, since
4 × - 3 = - 12 and 4 - 3 = + 1, thus
