Hello! answer: 516
Step-by-step explanation:
15 × 8 = 120
15 × 8 = 120
15 × 6 = 90
15 × 6 = 90
8 × 6 = 48
8 × 6 = 48
120 + 120 + 90 + 90 + 48 + 48 = 516

The same exponential growth function can be written in the forms y() - yo e t, y(t)- yo(1 r, and y) yo2 2. Write k as a function of r, r as a function of T2, and T2 as a function of k Write k as a function of r. k(r)-
Answers
Answer:
[tex](a)\ k(r) = \ln(1+r)[/tex]
[tex](b)\ r(T_2) = 2^{1/T_2}-1[/tex]
[tex](c)\ T_2(k) = \frac{\ln(2)}{k}[/tex]
Step-by-step explanation:
Given
[tex]y(t) = y_0e^{kt}[/tex]
[tex]y(t) = y_0(1+r)^t[/tex]
[tex]y(t) = y_02^{t/T_2}[/tex]
Solving (a): k(r)
Equate [tex]y(t) = y_0e^{kt}[/tex] and [tex]y(t) = y_0(1+r)^t[/tex]
[tex]y_0e^{kt} = y_0(1+r)^t[/tex]
Cancel out common terms
[tex]e^{kt} = (1+r)^t[/tex]
Take ln of both sides
[tex]\ln(e^{kt}) = \ln((1+r)^t)[/tex]
Rewrite as:
[tex]kt\ln(e) = t\ln(1+r)[/tex]
Divide both sides by t
[tex]k = \ln(1+r)[/tex]
Hence:
[tex]k(r) = \ln(1+r)[/tex]
Solving (b): r(T2)
Equate [tex]y(t) = y_02^{t/T_2}[/tex] and [tex]y(t) = y_0(1+r)^t[/tex]
[tex]y_0(1+r)^t = y_02^{t/T_2}[/tex]
Cancel out common terms
[tex](1+r)^t = 2^{t/T_2}[/tex]
Take t th root of both sides
[tex](1+r)^{t*1/t} = 2^{t/T_2*1/t}[/tex]
[tex]1+r = 2^{1/T_2}[/tex]
Make r the subject
[tex]r = 2^{1/T_2}-1[/tex]
Hence:
[tex]r(T_2) = 2^{1/T_2}-1[/tex]
Solving (c): T2(k)
Equate [tex]y(t) = y_02^{t/T_2}[/tex] and [tex]y(t) = y_0e^{kt}[/tex]
[tex]y_02^{t/T_2} = y_0e^{kt}[/tex]
Cancel out common terms
[tex]2^{t/T_2} = e^{kt}[/tex]
Take ln of both sides
[tex]\ln(2^{t/T_2}) = \ln(e^{kt})[/tex]
Rewrite as:
[tex]\frac{t}{T_2} * \ln(2) = kt\ln(e)[/tex]
[tex]\frac{t}{T_2} * \ln(2) = kt*1[/tex]
[tex]\frac{t}{T_2} * \ln(2) = kt[/tex]
Divide both sides by t
[tex]\frac{1}{T_2} * \ln(2) = k[/tex]
Cross multiply
[tex]kT_2 = \ln(2)[/tex]
Make T2 the subject
[tex]T_2 = \frac{\ln(2)}{k}[/tex]
Hence:
[tex]T_2(k) = \frac{\ln(2)}{k}[/tex]

Answer:
k = 8
Step-by-step explanation:
A slope of 3 means that y increases by 3 when x increases by 1.
The second point (2, k) has an x-value (2) that is 1 more than the x-value (1) of the first point (1, 5). This means the y-value (k) of the second point (2, k) will be 3 more than the y-value (5) of the first point (1, 5).
k = 5 + 3 = 8

When the sum of digits in a column equals or exceeds the base, then 1 is carried to the next column to the left, and the excess is written as the sum of the column. In base 2, this means 1+1 = 10. In base 4, this means 3+1=10, or 1+2+2=11.
Subtraction of a larger digit from a smaller one can be done by "borrowing" 1 (the amount of the base) from the next column to the left. In base 8, for example, this means 32-7 = 23.
These rules are identical to the rules that apply in base ten arithmetic.

He gave $100 to the local charity
Step-by-step explanation:
1/5 of 500 is 100
Answer:
$100
Step-by-step explanation:
This question asks how much of his money he gave to charity, meaning we must find 1/5 of 500. An easy way to mentally solve this is by dividing 500 into 5 separate, equal parts. This can be done by dividing 500 by 5. If you don't know what 500/5 is you can ignore the 0s for now and just divide 5/5, which is 1. Then, add the 0s back on for an answer of 100. Therefore, because 100 is 1/5 of 500 it must be the answer.

Given the vector u with magnitude 8 and direction 150° and the vector v with magnitude 3 and direction 115º, find the components of the vector u + v. Round to
four decimal places
Answers
======================================================
Explanation:
Vector u has magnitude 8 and direction 150 degrees.
So r = 8 and theta = 150
The polar form
r*(cos(theta)+i*sin(theta))
updates to
8*(cos(150)+i*sin(150))
---------------------
Use your calculator to evaluate that last expression to get it into a+bi form
8*(cos(150)+i*sin(150))
8*(-0.866025 + i*0.5)
-6.9282 + 4i
So this is the a+bi form of vector u. It's a rough approximation of it.
-----------------------
Repeat those steps for vector v
v = r*(cos(theta)+i*sin(theta))
v = 3*(cos(115)+i*sin(115))
v = 3*(-0.422618 + i*0.906308)
v = -1.267854 + 2.718924i
----------------------
We're converting each vector to a+bi form so that we can add the vectors.
The general idea is that if you want to add v = a+bi and w = c+di, then
v+w = (a+c)+(b+d)i
we simply add the corresponding real components together, and the imaginary components are added together as well.
-----------------------
Add up u and v
u+v = (-6.9282 + 4i) + (-1.267854 + 2.718924i)
u+v = (-6.9282 + -1.267854) + (4i + 2.718924i)
u+v = -8.196054 + 6.718924i
When rounding to four decimal places, the real and imaginary components are -8.1961 and 6.7189 respectively. These represent the x and y components of the vector.
So we can say vector u+v is approximately < -8.1961, 6.7189 >
A projectile is fired straight up from ground level with an initial velocity of 112 ft/s. Its height, h, above the ground after t seconds is given by h = –16t2 + 112t. What is the interval of time during which the projectile's height exceeds 192 feet?
Answers
Answer:
Step-by-step explanation:
We can do this the easy way and just set up an inequality and let the factoring do the work for us. The inequality will look like this:
[tex]-16t^2+112t>192[/tex] We will move the constant over and get
[tex]-16t^2+112t-192>0[/tex] and when you factor this you get that
3 < t < 4
Between 3 and 4 seconds is where the projectile reaches a height higher than 192 feet. With a little more work and some calculus you can find the max height to be 196 feet.

Tan 65° = Opp/Adj
Tan 65° = x/10

[tex] \frac{dr}{dt} = 6.79 \: \frac{m}{s} [/tex]
Step by Step Explanation:
The area a is defined as
[tex]a = \pi {r}^{2} [/tex]
Now take derivative of the above expression with respect to time:
[tex] \frac{da}{dt} = 2\pi r \frac{dr}{dt} [/tex]
Solving for dr/dt, we then get
[tex] \frac{dr}{dt} = \frac{1}{2\pi r} \frac{da}{dt} [/tex]
Note that da/dt = 900 m^2/s and when the area of the oil slick is 1400 m^2, the radius r is r = √(1400/π) = 21.1 m. Therefore,the rate at which the radius is increasing dr/dt is
[tex] \frac{dr}{dt} = \frac{1}{2\pi(21.1 \: m)}(900 \frac{ {m}^{2} }{s} ) = 6.79 \frac{m}{s} [/tex]

Answers
Step-by-step explanation:
missing where ?
I guess you mean that there is one element missing between 51 and 33 (based on the readable answer options).
if that is true, then the missing element is 42.
the difference between 60 and 51 is 9.
the difference between 51 and 33 is 18.
if there is an engender missing in between 51 and 33, then it is logical to put it in the middle cutting the interval of 18 in half to 2 times 9. which is also supported by the first interval between 60 and 51 (9).
so, it would be 51 -9 = 42

The first one is 145 in^2 and the other is 250 in^2
Step-by-step explanation:
For the first one you have to find the base first so 5*5=25, then you find the area of the other faces and since theres 4 of them dont bother diving them by 2 and just do it twice, so the faces would be 120 in^2 in all add it together and you get 145
For the second one its the same thing but instead of a square base its a triangle so theres only 3 faces. 8*10 = 80/2 =40, 2 of the faces are 140 in all and to find the last one just 14*10=140/2=70 and you add them together and get 250

Answer:
for the lengths, just double the numbrrs

bc the scale factor is two (the upper edge is given)
the angles are just the same, no matter the zoom factor
There are two polygons where B is greater than A.
One side in polygon A has a length of 2.5 and the corresponding length in polygon B is 5.
So, the scale factor is
[tex]\dfrac{5}{2.5}=2[/tex]
So, the missing sides in polygon B are
[tex]1.5\times2=3[/tex]
[tex]2.5\times 2=5[/tex]
The angles in polygon A will be the same as B as all the sides of the polygon have changed according to the scale factor.
So, the missing sides in polygon B are 3 and 5, and the angles in polygon A are [tex]53^{\circ}[/tex] and [tex]82^{\circ}[/tex].
