Answer:
y = 19*(8)^x
Step-by-step explanation:
We want to write an equation like:
y = a*b^x
That goes through the points (0, 19) and (3, 9728)
Then, when x = 0, we must have y = 19
Replacing those values in the equation we get:
19 = a*b^0 = a*1 = a
19 = a
Then the equation is:
y = 19*b^x
We also know that when x = 3, y = 9728
If we replace these values in the equation, we get:
9728 = 19*(b)^3
Let's solve this for b.
9728/19 = b^3
512 = b^3
∛512 = b = 8
Then the equation is:
y = 19*(8)^x

4 people are going to a dinner party. Each person at
the party will eat pound of cake. If you can only buy
whole pounds of cake, how many pounds should you
buy?
Answer:
92 pounds
Step-by-step explanation:
Here is the complete question ;
4 people are going to a dinner party. Each person at the party will eat 23 pound of cake. If you can only buy whole pounds of cake, how many pounds should you buy?
total pounds to be bought = number of people at the party x total pounds they would eat
4 x 23 = 92 pounds
The price of a watch was increased by 20% to £162.
What was the price before the increase?
Answer: = £135
Step-by-step explanation:
Original price = 100%
Percentage increase = 20%
New price = 100% + 20% = 120%
If 120% = £162
What about 100% = ?
= (100 x 162) ÷ 120
= 16200 ÷ 120
= £135.

The Jacksons are taking out a $35,000 loan to remodel their home. The tables below show the rates for a 1-year and 5-year loan from two different lenders. Complete each table to calculate the total repayment and interest paid for each loan offer.
Answer:
look at the screenshot
Step-by-step explanation:
look at the screenshot
The table for total repayment and interest paid for each loan offer:
Loan offer Interest rate Total repayment Total interest paid
1-year loan 6.5% $37,275 $2,275
5-year loan 8.2% $41,570 $6,570
What is simple interest?Simple interest is an amount which is calculated for a certain period of time and for a certain rate, in simple interest calculation there are three factors which we consider: principal amount(P), rate(R) and time(T).
Formula; Simple Interest(I) = P × R × T/100
For the 1-year loan, the total repayment and total interest paid can be calculated as follows:
Total repayment = Principal + Interest = $35,000 + (0.065 x $35,000)
= $37,275
Total interest paid = $37,275 - $35,000
= $2,275
For the 5-year loan, the total repayment and total interest paid can be calculated as follows:
Total repayment = Principal + Interest
= $35,000 + (0.082 x $35,000 x 5)
= $41,570
Total interest paid = $41,570 - $35,000 = $6,570
Loan offer Interest rate Total repayment Total interest paid
1-year loan 6.5% $37,275 $2,275
5-year loan 8.2% $41,570 $6,570

6 x 2 = 12
so 2 is the width.
Slope of the line pls helpppppp
Answer:
[tex] slope(m) = \frac{3}{2} [/tex]
Step-by-step explanation:
Slope (m) = change in y / change in x = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Use any two pairs of values to find the slope. Thus, let's use (-14, 3) and (-12, 6):
Where,
[tex] (-14, 3) = (x_1, y_1) [/tex]
[tex] (-12, 6) = (x_2, y_2) [/tex]
Plug in the values
[tex] m = \frac{6 - 3}{-12 -(-14)} [/tex]
[tex] m = \frac{3}{2} [/tex]
La funcion que representa el beneficio obtenido por una empresa si vende x unidades de uno de sus productos es f(x)= -70x^2+2800x-45000. ¿cuantas unidades tiene que vender para maximizar sus beneficios?
Answer:
[tex]20[/tex]
Step-by-step explanation:
La función es
[tex]f(x)=-70x^2+2800x-45000[/tex]
Diferenciando con respecto a [tex]x[/tex] obtenemos
[tex]f'(x)=-140x+2800[/tex]
Igualar con cero
[tex]0=-140x+2800\\\Rightarrow x=\dfrac{2800}{140}\\\Rightarrow x=20[/tex]
Doble derivada de la función
[tex]f''(x)=-140<0[/tex]
Entonces, la función es máxima cuando el número de unidades vendidas, [tex]x=20[/tex],

how do I work it out ?
Answer:
x - y = 5
Explanation:
As you can see in the first problem the ration is x to y = 8 to 3. This means for every 8 x values, there are 3 y values. Therefore, x - y should be the same as 8 - 3, which is 5.
this is the third time and i a really annoyed as i am having my time wasted and points

Answer: A) 20.9 ; B) 34years
Step-by-step explanation:
Given the following :
AGE (X) - - - - - - - 19 - -20 - - - 21 - - - 22 - - - 23
FREQUENCY (F) - 2 - - 3 - - - - 1 - - - - 4 - - - - 1
A)
MEAN(X) = [AGE(X) × FREQUENCY (F)] ÷ SUM OF FREQUENCY
F*X = [(19 * 2) + (20 * 3) + ( 21 * 1)+(22 * 4)+(23 * 1)]
= 38 + 60 +21 + 88 + 23 = 230
SUM OF FREQUENCY = 2 + 3 + 1 + 4 + 1= 11
MEAN(X) = 230 / 11
X = 20.9
B)
WHEN A NEW PLAYER WAS ADDED :
MEAN (X) = 22
Let age of new player = y
Sum of Ages = 19 + 19 +20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 + y
Number of players = 11 + 1 = 12
Mean(x) = sum of ages / number of players
New mean (x) = 22
x = (230 + y) / 12
22 = (230 + y) / 12
Cross multiply
264 = 230 + y
y = 264 - 230
y = 34 years
Alisha hiked a trail that was 9/10 mile and Joseph hiked a trail that was 5/10 mile. How much farther did Alisha hike than Joseph?
Answer:
4/10 or 2/5 of a mile more.
Step-by-step explanation:
Since the denominators are the same, all you have to do is subtract the numerators.
9-5=10.
Therefore, Alisha hiked 2/5 of a mile further than Joseph.

solve the system of equations -4x- y = -18 and 2x + 3y = 24 by combining the equations
Answer:
x = 3
y = 6
Step-by-step explanation:
-4x- y = -18
2x + 3y = 24 (Multiply everything by 2)
-4x - y = -18
4x + 6y = 48
5y = 30
y = 6
-4x- y = -18
-4x - 6 = -18
-4x = -12
x = 3

What are all of step to get 3m+4=1
Answer:
Step-by-step explanation:
3m=-3
m=1
Answer:
m = -1
Step-by-step explanation:
3m + 4 = 1
subtract 4 from each side of the equation:
3m + 4 - 4 = 1 - 4
3m = -3
divide both sides by 3:
3m/3 = -3/3
m = -1
