Answer: Approximately 8 minutes and 20 seconds
This is equivalent to 500 seconds.
==============================================
Explanation:
Any electromagnetic wave travels at the speed of light in a vacuum.
The speed of light is about 300,000 km per second.
time = distance/speed
time = (150,000,000 km)/(300,000 km per second)
time = 500 seconds
It takes about 500 seconds for an electromagnetic wave to go from the sun to the earth.
-----------
Divide by 60 to find the minutes and seconds
500/60 = 8 remainder 20
500 seconds = 8 minutes & 20 seconds

A deli sandwich is placed inside a cooler. As the sandwich cools, its temperature C(t) in degrees Celsius after t minutes is given by the following exponential function.
C(t) = 21 (0.91)^t
(a) find the initial temperature: ___C
(b) does the function represent growth or decay? growth or decay
(c) by what percent does the temperature change each minute? ____ %
The initial temperature was 21 degrees Celsius, the function represents the decay and the rate is 9%
What is exponential decay?During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.
We have:
A deli sandwich is placed inside a cooler. As the sandwich cools, its temperature C(t) in degrees Celsius after t minutes:
The function is:
[tex]\rm C(t) = 21 (0.91)^t[/tex]
a) To find the initial temperature:
Plug t = 0
C(0) = 21 degree Celsius
b) The function represents the decay because the base of the exponent is less than 1.
c) To find the rate compared with the exponential decay function:
[tex]\rm A = a(1 - r)^t[/tex]
1 - r = 0.91
r = 0.09
or
r = 9%
Thus, the initial temperature was 21 degrees Celsius, the function represents the decay and the rate is 9%

Josh has 8 days to make pots and plates to sell at a local fair. Each pot weighs 2 pounds and each plate weighs 1 pound. Josh cannot carry more than 50 pounds to the fair. Each day, he can make at most 5 plates and at most 3 pots. He will make $12 profit for every plate and $25 profit for every pot that he sells.
a. Write linear inequalities to represent the number of pots p and plates a Josh may bring to the fair.
b. List the coordinates of the vertices of the feasible region.
c. How many pots and how many plates should Josh make to maximize his potential profit?
The optimal number of pots and plates Josh should make is given from
the graph of the inequalities.
Response:
a. 2·p + a ≤ 50
p ≤ 24
a ≤ 40
b. The coordinates of the vertices of the feasible region are; (24, 2), (40, 5), (0, 40), (24, 0), (0, 0)
c. 40 pots and 5 plates
How can the optimal number of plates and pots Josh should make be found?Given:
Number of days Josh has to make pots and plates to sell = 8 days
Weight of each pot = 2 pounds
Weight of each plate = 1 pound
Weight Josh cannot carry = More than 50 pounds
Number plates he can make each da = At most 5 plates
Number of pots he can make each day = At most 5 pots
The profit Josh makes for each plate sold = $12
Profit from each pot sold = $25
a. Let p represent the number of pots Josh makes and let a represent the
number plates. The linear inequalities are;
2·p + a ≤ 50
p ≤ 8 × 3 = 24
p ≤ 24
a ≤ 5 × 8 = 40
a ≤ 40
b. When p = 24, we have;
2 × 24 + a = 50
a = 2
When a = 40, 2·p + 40 = 50, gives;
p = 5
The vertex points are;
The coordinates of the vertices of the feasible region are;
(24, 2), (40, 5), (0, 40), (24, 0), (0, 0)
c. The profit function is; P = 25·p + 12·a
The profit at the vertices are;
[tex]\begin{tabular}{|c|c|c|}p&a&Profit\\0&0&0\\0&40&12 \times 40 = 480\\24&0&25 \times 24 = 600\\24&2&12 \times 2 + 25 \times 40 = 624\\40&5&12 \times 5 + 25 \times 40 = 660\end{array}\right][/tex]
To maximize his potential profit, therefore;
Josh should make 40 pots and 5 plates.Learn more about linear optimization here:

Answer:
∠ ADC = 160°
Step-by-step explanation:
let ∠ CDB = n then ∠ ADC = 8n
The 2 angles are adjacent and lie on a straight line and sum to 180° , then
n + 8n = 180, that is
9n = 180 ( divide both sides by 9 )
n = 20
Then
∠ ADC = 8n = 8 × 20 = 160°

10 The evolution of the value of a share during the 10 weeks following its purchase is described below.
reach $9. An increase in the price of oil then causes its value to fall during the 2 weeks
The value of the stock when purchased is $5. Over the next 3 weeks, its value increases to
subsequent shares, the share then reaching its minimum value, i.e. $2. The value of the share remains
constant for 3 weeks, then increases by $6 over the next 2 weeks.
We are interested in the function that associates the value (in $) of the action with the time (in weeks) elapsed since
its purchase.

Which expression represents a quadratic expression in complete factored form?
Α.
(x + 4)(x-3)
B.
(2x+4)(x+3)
C.
(x - 1)(3x-9)
D.
(x-2) + (x + 3)
Answer:
C. (x + 4)(x − 3)
Step-by-step explanation:
A quadratic expression in complete factored form can be written as the product of two linear factors, where each factor is in the form of (ax + b). The expression (x + 4)(x - 3) is in this form and can be expanded to the quadratic expression x^2 + x - 12.
Option A is a sum of two linear expressions, but it is not factored. Option B is a product of two linear expressions, but it can be simplified to the quadratic expression 3x^2 - 3x. Option D is a product of two linear expressions, but it can be simplified to the quadratic expression 2x^2 + 10x + 12.

Answer:
u = 4
v = 18
Step-by-step explanation:
in a parallelogram, diagonals bisect each other into two equal segments so we can do the following:
2u+2 = 5u-10
subtract '2u' from each side to get:
2 = 3u-10
add 10 to each side to get:
12 = 3u
12/3 = u
u = 4
To solve for 'v':
v/3 = 6
multiply each side by 3 to get:
v = 18

Help!!!! This is geometry, the picture has the question!
Answer:
LN = 16
Step-by-step explanation:
MO bisects LN into two equal parts (If you see a triangle MNL, the line in the middle 5y - 8 is a median. This means x + 6 = 4x)
x + 6 = 4x
3x = 6
x = 2
Substitute x
LN = 2 + 6 + 8 = 16
LN = 16
