You want the 60th term of the arithmetic (?) sequence given.

Formula

L = a + (n - 1)*d

Givens

L = ?

a =  8

d = 8

n = 60

Solution

L = 8 + (60 - 1)*8

L = 8 + 60*8 - 8

L = 480

Answer

The 60th term is 480

Answer:

Step by step explanation :

As we know

[tex]\:\bf\boxed{an\:=\:a\:+\:(n\:-\:1)\:d}[/tex]

where,

an = the nth term in the sequence

n = the term

d = common difference

a = first term of the AP.

Here,

an = a60

n = 60

d = 16 - 8 = 8

a = 8

Now,

[tex]\:\mathsf{a60\:=\:8\:+\:(60\:-\:1)(8)}[/tex]

=> [tex]\:\mathsf{a60\:=\:8\:+\:(59)(8)}[/tex]

=> [tex]\:\mathsf{a60\:=\:8\:+\:472}[/tex]

=> [tex]\:\bf{a60\:=\:480}[/tex]

Therefore the 60th term of the AP is 480.

The approximate change that Thomas will see on his future monthly statements as a result of the change is; $33.1975

We are told that Thomas' insurance company has increased his annual premium by $398.37.

Now, the premium above is the change in his annual premium. Thus, to find the change in his monthly premium, we just divide by 12 months to get;

Change in Monthly statements = $398.37/12

Change in Monthly statements = $33.1975

Answer:

x ≤ 3

Step-by-step explanation:

[tex]\dfrac{1}{2}-\dfrac{1}{4}x \geq -\dfrac{1}{4}[/tex]

Subtract 1/2 from both sides:

[tex]\implies \dfrac{1}{2}-\dfrac{1}{4}x-\dfrac{1}{2} \geq -\dfrac{1}{4}-\dfrac{1}{2}[/tex]

[tex]\implies -\dfrac{1}{4}x \geq -\dfrac{3}{4}[/tex]

Multiply both sides by 4:

[tex]\implies -\dfrac{1}{4}x \cdot 4 \geq -\dfrac{3}{4} \cdot 4[/tex]

[tex]\implies -x \geq -3[/tex]

Divide both sides by -1 (remembering to flip the sign):

Answer:

(E) < BDE = 2x + y.

Step-by-step explanation:

As  triangle ABC is isosceles the 2 base angles are equal.

Therefore m < BAC = x.

Consider triangle ABD:

m < BDE = m < BAC + m < ABD ( external angle of a triangle theorem)

So < BDE =  x + x + y = 2x + y.

Answer:

y = 12

Step-by-step explanation:

To solve this equation... The function is basically:

y = 3x - 15

So by substituting in x=9:

y = 27 - 15 = 12.

y = 12

Hope this helps.

Answer:

y = 12

Step-by-step explanation:

f(x) = y, so to find y, we jut need to substitute 9 for all the x-values in the equation:

f(9) = 3(9) - 15

Simplify:

f(9) = 27 - 15

f(9) = 12

Since f(x) = y

y = 12 when x is 9

Answer:

T' = (-8, 8)

U' = (2, 8)

V' = (-8, 7)

Step-by-step explanation:

reflection over x axis means we change the sign of the y coordinate and nothing else

T = (-8, -8)

y coordinate = -8, change the sign to get 8

T' is thus (-8, 8)

U = (2, -8)

y coordinate = -8, y' = 8

U' = (2, 8)

V = (-8, -7)

y' = 7

V' = (-8, 7)

Math dimensions include length, width, and height (in that order). The dimension that an object occupies is dependent on how many different measurements, aka dimensions, an object has.

0th Dimension

The first dimension is actually the zeroth dimension. This dimension includes objects that do not have any measurements. A point does not have a length because it only occupies one spot on a plane.

The 0th dimension includes:

1st Dimension

The next dimension, the 1st dimension, has only length. This means the object can travel across the x-axis, but it can only go in one direction.

The 1st dimension includes:

2nd Dimension

For this question, the last dimension is the 2nd dimension. The 2nd dimension has both length and width. This means that the object occupies both the x and y-axis.

The 2nd dimension includes:

3rd Dimension

The 3rd dimension is not included in the question or the answer choices but is still important. The 3rd dimension has length, width, and height. This occupies the x, y, and z-axis and cannot be graphed on a regular geometric plane. The 3rd dimension is graphed in a geometric space.

The 3rd dimension includes:

Answer:

5x - 2

Step-by-step explanation:

if x is your number its 5 lots of your number - 2

Step-by-step explanation:

length × width = 24

2×length + 2×width = 22

length + width = 11

length = 11 - width

this we use in the first equation again :

(11 - width) × width = 24

11×width - width² = 24

width² - 11×width + 24 = 0

the general solution to an quadratic equation :

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = width

a = 1

b = -11

c = 24

and so we get

width = (11 ± sqrt((-11)² - 4×1×24))/2×1) =

= (11 ± sqrt(11² - 96))/2 = (11 ± sqrt(121-96))/2 =

= (11 ± sqrt(25))/2 = (11 ± 5)/2

width1 = (11 + 5)/2 = 16/2 = 8 cm

width2 = (11 - 5)/2 = 6/2 = 3 cm

and teenaged to this is then

length1 = 11 - width1 = 11 - 8 = 3 cm

length2 = 11 - width2 = 11 - 3 = 8 cm

so, it is clear. one dimension has to be 8 cm, and the other one 3 cm. it does not matter which is which.

Problem 4

The template of [tex]y = a*b^x[/tex] becomes [tex]y = 10800*0.975^x[/tex] to represent the exponential function.

We want to know when the population reaches half of 10800, so we want to know when the population is 10800/2 = 5400

Plug in y = 5400 and solve for x.

[tex]y = 10800*0.975^x\\\\5400 = 10800*0.975^x\\\\0.975^x = 5400/10800\\\\0.975^x = 0.5\\\\\log(0.975^x) = \log(0.5)\\\\x\log(0.975) = \log(0.5)\\\\x = \log(0.5)/\log(0.975)\\\\x \approx 27.377851\\\\x \approx 28\\\\[/tex]

I rounded up to the nearest whole number because x = 27 leads to y = 5452, which is not 5400 or smaller.

Luckily, x = 28 leads to y = 5315 which gets over the hurdle of being 5400 or smaller.

Add 28 years onto the starting year 2002 and we get to 2002+28 = 2030

The population reaches half of its original amount in the year 2030.

============================================================

Problem 5

If the car loses 12% of its value each year, then it keeps the remaining 88%

Plug those values into [tex]y = a*b^x[/tex].

We find the equation is [tex]y = 28750*0.88^x[/tex] where,

Replace y with 10,000 and solve for x.

[tex]y = 28750*0.88^x\\\\10000 = 28750*0.88^x\\\\0.88^x = 10000/28750\\\\0.88^x \approx 0.347826\\\\\log(0.88^x) \approx \log(0.347826)\\\\x\log(0.88) \approx \log(0.347826)\\\\x \approx \log(0.347826)/\log(0.88)\\\\x \approx 8.261168\\\\x \approx 9\\\\[/tex]

Like in the previous problem, we round up so we clear the hurdle.

Adding 9 years onto 2012 gets us to 2012+9 = 2021

Answer:

Exponential Function

General form of an exponential function: [tex]y=ab^x[/tex]

where:

If b > 1 then it is an increasing function

If 0 < b < 1 then it is a decreasing function

Given:

As the population is decreasing by 2.5% each year, the population will be 100% - 2.5% = 97.5% of the previous year. Therefore, the base is 0.975.

Final equation:  [tex]\large \text{$ y=10800(0.975)^x $}[/tex]

Half of population:  10800 ÷ 2 = 5400

[tex]\large \begin{aligned}y & =5400\\\implies 10800(0.975)^x & =5400\\(0.975)^x & = \dfrac{5400}{10800}\\(0.975)^x & = 0.5\\\ln (0.975)^x & = \ln 0.5\\x \ln 0.975 & = \ln 0.5\\x & = \dfrac{\ln 0.5}{\ln 0.975}\\x & = 27.377785123\end{aligned}[/tex]

2002 + 27.37785... = 2029.37785...

Therefore, the population will reach half during 2029 (by 2030).

Given:

As the value is decreasing by 12% each year, the value will be 100% - 12% = 88% of the previous year. Therefore, the base is 0.88.

Final equation:  [tex]\large \text {$ y=28750(0.88)^x $}[/tex]

Find when the car is worth $10,000:

[tex]\large \begin{aligned}y & = 10000\\\implies 28750(0.88)^x & = 10000\\(0.88)^x & = \frac{10000}{28750}\\(0.88)^x & = \frac{8}{23}\\\ln (0.88)^x & =\ln \left(\frac{8}{23}\right)\\x \ln (0.88) & =\ln \left(\frac{8}{23}\right)\\x & =\dfrac{\ln \left(\frac{8}{23}\right)}{\ln (0.88)}\\x & = 8.26116578\end{aligned}[/tex]

2012 + 8.26116578.. = 2020.26116578..

Therefore, the value of the car will reach $10,000 during 2020 (by 2021).
