Answer:
[tex]A_4[/tex]
Step-by-step explanation:
The cost of the e-readers and the subscription of their services are
[tex]A_1(t)=5t+350[/tex]
[tex]A_2(t)=10t+250[/tex]
[tex]A_3(t)=499[/tex]
[tex]A_4(t)=15t+179[/tex]
The functions are of the form
[tex]A(t)=mt+c[/tex]
Where [tex]m[/tex] is the monthly subscription cost and [tex]c[/tex] is the cost of the e-reader.
So, 15 dollars is the highest subscription cost which is of the 4th e-reader.
Hence [tex]A_4[/tex] has the highest subscription cost.

What is the percent Of decrease from 50 to 21
Please anwser accurate and I give brailiest
Answer:
29%
Step-by-step explanation:
To find the decrease from 50 to 21 you would subtract 50 - 21. You get 29. This is the same as 29/100. 29/100 is also 0.29 or 29%.
Hope it helps! (I'm so sorry if it's incorrect).

What is an equation of the line that passes through the points (5, 8) and (5,3)?
Answer:
x = 5
Step-by-step explanation:
to find the slope of the line you take the difference of the y-values divided by the difference of the x-values; the denominator results in zero
When the denominator for slope is zero then you know the line will not intersect the y-axis at all and the line will be vertical and intersect the x-axis at the x-coordinate of any known point
any fraction with zero in the denominator is considered to be 'undefined'
any fraction with zero in the numerator is zero

Frankie borrowed 800 for 6 years. He is charged 5% simple interest. How much interest will he pay in 6 years
Answer: The required simple interest = $240
Step-by-step explanation:
Formula for simple interest:
Interest = Principal x rate x time
Given: Principal = $800
rate of interest = 5% = 0.05
Time = 6 years
Interest = 800 x 0.05 x 6 = $240
Hence, the required simple interest = $240

Somebody help!!! Please!!!
Answer:
y = -1 !!!!!!!!!!! :)))))))))))))
Answer:
y=-1
Step-by-step explanation:
symmetry is where it is the same on both sides, so that would be the line between the top and bottom point and because they are up and down it is a y whereas if it were side to side it would be x. it is on the left side which are negatives and it is one over to the left making it y=-1
Burt's grandparents started a savings account for him when he was born. They invested
$1250 in an account that pays 7.5% interest every year. How much money is in the
account on Burt's 18th birthday?
Answer:
4594.76 USD will be in the account on Burt's 18th birthday.
Step-by-step explanation:
Since interest rate is constant in time, we can use the definition of composite interest to determine how much money will be on Burt's 18th birthday, that is:
[tex]C = C_{o}\cdot \left(1+\frac{r}{100} \right)^{t}[/tex] (1)
Where:
[tex]C_{o}[/tex] - Initial amount, measured in US dollars.
[tex]C[/tex] - Current amount, measured in US dollars.
[tex]r[/tex] - Annual interest rate, measured in percentage.
[tex]t[/tex] - Time, measured in years.
If we know that [tex]C_{o} = 1250\,USD[/tex], [tex]r = 7.5[/tex] and [tex]t = 18[/tex], then the money in the savings account on Burt's 18th birthday is:
[tex]C = (1250\,USD)\cdot \left(1+\frac{7.5}{100} \right)^{18}[/tex]
[tex]C = 4594.76\,USD[/tex]
4594.76 USD will be in the account on Burt's 18th birthday.
please help, the word cut off is slope: 3
Answer:
1. y=3x-2
2. y=-1/4x+5
These equations are in slope-intercept form (y=mx+b). IN this equation m represents the slope and b represents the y intercept. Therefore, y=3x-2 and y=-1/4x+5 are correct
Step-by-step explanation:
Put the following equation of a line into slope-intercept form, simplifying all
fractions.
6x – 15y = 135
Answer:
Step-by-step explanation:
Slope-intercept form means the equation of a line should be in this form:
[tex]y=mx+b[/tex]
So we re-write our equation into this form like this:
[tex]6x-15y=135\\-15y=-6x+135\\y=\frac{-6x+135}{-15} \\\\y=\frac{-6x}{-15}+\frac{135}{-15} \\\\y=\frac{2}{5}x-9 \\[/tex]

What is the value of x? There is isosceles triangle. The measure of angle which is between two congruent sides is (6x+10⁰). The measures of other angles are (x+17⁰) and (4x-34⁰).
x=17
step-by-step Explanation:-[tex]{\boxed{\quad\:\mapsto\rm Firstly\:Let's\:understand\:the\:concept:-}}[/tex]
This is a isosceles triangle. As it is a triangle we can apply sum theory. we have to take the sum of given unknown polynomials as 180° .Then by solving it we can find the value of x.
Solution:-Given angles
(6x+10°)(x+17°)(4x-34)°According to sum theory
[tex]{\boxed{\sf The \:sum\:of\:angles=180°}}[/tex]
Substitute the values[tex]\qquad \quad{:}\longmapsto\tt (6x+10)+(x+17)+(4x-34)=180 [/tex]
Remove brackets[tex]\qquad \quad{:}\longmapsto\tt 6x+10+x+17+4x-34=180 [/tex]
Together like polynomials and constants[tex]\qquad \quad{:}\longmapsto\tt 6x+x+4x+10+17-34=180 [/tex]
[tex]\qquad \quad{:}\longmapsto\tt 11x-7=180 [/tex]
Interchange sides[tex]\qquad \quad{:}\longmapsto\tt 11x=180+7 [/tex]
[tex]\qquad \quad{:}\longmapsto\tt 11x=187 [/tex]
[tex]\qquad \quad{:}\longmapsto\tt x=\cancel{\dfrac{187}{11}}[/tex]
Simplify[tex]\qquad \quad{:}\longmapsto\tt x=17[/tex]
[tex]\therefore\sf The \:value\:of\:x\;is\:17.[/tex]

Step-by-step explanation:
If the temperature outside increases by 3 1/2 degrees every 1 1/2 hours, by how much will the temperature increase after 4 hours?
please answer in fractions.
Part 1:
What is the rate per hour of the temperature increase?
Part 2:
How much will the temperature increase after 4 hours?
Answer:
2 1/3 ; 9 1/3
Step-by-step explanation:
Given that:
Outside temperature increases by 3 1/2 degrees every 1 1/2 hours
The rate per hour of temperature increase will be :
Let rate per hour = x
3 1/2 = 1 1/2
x = 1
Cross multiply :
1 1/2 * x = 3 1/2 * 1
3x/2= 7/2
Multiply both sides by 2/3
3x/2 * 2/3 = 7/2 * 2/3
x = 14/ 6
x = 2 2/6
x = 2 1/3
Hence, outside temperature increases at the rate of 2 1/3 degrees per hour.
2.) Temperature increase after 4 hours :
(Temperature rate per hour * number of hours)
(2 1/3) * 4
(7/3) * 4
28 / 3
= 9 1/3
Hence, temperature increase after 4 hours = 9 1/3
2 1/3 ; 9 1/3
Step-by-step explanation:
Given that:
Outside temperature increases by 3 1/2 degrees every 1 1/2 hours
The rate per hour of temperature increase will be :
Let rate per hour = x
3 1/2 = 1 1/2
x = 1
Cross multiply :
1 1/2 * x = 3 1/2 * 1
3x/2= 7/2
Multiply both sides by 2/3
3x/2 * 2/3 = 7/2 * 2/3
x = 14/ 6
x = 2 2/6
x = 2 1/3
Hence, outside temperature increases at the rate of 2 1/3 degrees per hour.
2.) Temperature increase after 4 hours :
(Temperature rate per hour * number of hours)
(2 1/3) * 4
(7/3) * 4
28 / 3
= 9 1/3
Hence, temperature increase after 4 hours = 9 1/3

Luiza starts collecting rare coins. In the first month of her collection, she has 25 coins. Each month since then, she has added 2 coins to her collection. How many coins will she have after 2 years?
Answer: 71 coins
Step-by-step explanation:
First and foremost, we should note that:
12 months = 1 year
2 years = 12 × 2 = 24 months
Since she has 25 coins in her first month and adds 2 coins to her monthly collections, this means that she has 23 more months. This can be expressed as:
= 25 + 2x
where, x = number of months
= 25 + 2(23)
= 25 + 46
= 71 coins
She will have 71 coins after 2 years.
From a point 300 feet above ground in a firetower, a ranger spots two fires in the George Washington National forest. The angle of depression made by the line of sight from the ranger to the first fire is 3oand the angle of depression made by the line of sight from the ranger tothe second fire is 2o. The angle formed by the two lines of sight is 0117. Find the approximate distance between the two fires.
Answer:
The answer is "[tex]\bold{17456.6 \ ft}[/tex]"
Step-by-step explanation:
Please find the complete question in the attached file.
[tex]\sin \theta = \frac{P}{h}\\\\\to BC =x\\\\\to BD =y\\\\[/tex]
The height of tower (AB) = 300 ft
Distance = CD
[tex]\Delta ABC \\\\\sin \theta = \frac{AB}{AC}\\\\\sin (2.5) = \frac{300}{AC}\\\\Ac= \frac{300}{\sin (2.5)}\\\\AC= 6877.68 \\\\\Delta ABD \\\\\sin \theta = \frac{AB}{AD}\\\\\sin (1.3) = \frac{300}{AD}\\\\AD= \frac{300}{\sin (1.3)}\\\\AC= 1322.33[/tex]
calculating CD :
[tex]CD^2 = AC^2 +AD^2 -2\cdot AC \cdot AD \cdot \cos(117^{\circ}) \\\\CD = \sqrt{(6877.68)^2 +(13223.23)^2 -2\cdot (6877.68) \cdot (13223.23) \cdot \cos(117^{\circ})}\\\\CD =\sqrt{47302482.1824 + 174853811.6329 - 82576463.207}\\\\CD= \sqrt{304732757.02}\\\\CD= 17456.6 \ ft[/tex]

Answer:
x = 1.73
y = 2.45
z = 1.41
Step-by-step explanation:
1/z = z/2
z^2 = 2
z = sqrt(2)
1^2 + z^2 = x^2
1 + 2 = x^2
x^2 = 3
x = sqrt(3)
z^2 + 2^2 = y^2
2 + 4 = y^2
y^2 = 6
y = sqrt(6)
x = 1.73
y = 2.45
z = 1.41
