In 1979, zoologists estimated the number of fish in a local pond to be about
540. In 1989, 10 years later, the zoologists estimated that the number of
fish had increased to 990. Assuming that the fish population increased
linearly, how many fish lived in the pond in 1986? *
ann
Answer:
693 fish
Step-by-step explanation:
In 10 years, we can tell that the amount of fish increased by 1.833...(990 divided by 540) times. If we divide 1.833... by 10, we can find how much the pond increases by yearly. we get 0.1833... If we multiply that by 7 (because the gap between 1986 and 1979 is 7 years), we get 1.2833... So, if we multiply 540 by 1.28333..., we get 693 fish.

Aaron puts $1,000 in an account that pays 10% interest compounded quarterly. He leaves it in the account for six months. Estimate how much interest he earns.
Answer: $50.63 --- Interest
Step-by-step explanation:
Step 1
Using the formulae
A = P(1 + r/n)^nt
Where
A = principal + interest Amount
P = Principal Amount = $1000
t = Time in years= 6months = 0.5 years
n = number of compounding periods= quarterly =4
Step 2
6 months = 6/12 = 0.5 years
Rate = 10 % = 0.1
A = P(1 + r/n)^nt
= 1000 ( 1 + 0.1/4)^(4 x 0.5)
=1000(1 +0.025)^2
= 1000(1.025)^2
= 1000 x 1.050625
A= $1,050.625
but A = principal + interest Amount
Interest = A- Principal=$1,050.625-$1,000
=$50.625

reflect point R(6,10 ) over the y-axis. The coordinates for R' are
Answer: (6,-10)
Step-by-step explanation:
When you reflect a point over the y-axis, the sign of the number changes. It goes from negative to positive and positive to negative. Since both our numbers are positive, only the y-coordinate become negative because it is only being reflected over the y-axis, not x-axis. (6,-10)
Write the equation g(x) of the transformation of the parent graph f(x) = |x| translated right 5 units.
Answer:
g(x) = |x-5|
Step-by-step explanation:
f(x) = |x|
y = f(x + C) C < 0 moves it right
g(x) = |x-5| moves it to the right 5 units
We start off with: f(x) = |x|
c < 0 means move right
y = f(x + c)
Move 5 units to the right
After: g(x) = |x - 5|

A used car is for sale for $8,950. If Jenny will pay for the car over a 5 year period, what will be her monthly payment, to the nearest dollar?
3,729/month
1,790/month
149/month
60/month
Answer:
your answer will be 149/month
Step-by-step explanation:
you wanna ask urself how many months are in 5 years
The answer is: 60 months
then, you wanna divide the cost of the car over 60 months
So:
[tex]$8950/60=149.166[/tex]
round that to the nearest dollar AKA the ones
it'll be 149
and don't forget the unit of time
which is month
$149/month

Expand each expressions and combine like terms if possible
-12(5/6x - 5) + 2x
Answer:
The answer is
60 - 8xStep-by-step explanation:
[tex] - 12( \frac{5}{6} x - 5) + 2x[/tex]
Using FOIL multiply the terms in the bracket
That's
[tex] - 12( \frac{5}{6} x) + 12(5) + 2x \\ \rarr \: \: - 10x + 60 + 2x[/tex]
Group like terms
That's

-A parabola that is vertically stretched by a factor of 2 sitting with its vertex on the x axis at x=-3
Answer:
f(x) = 2(x + 3)²
Step-by-step explanation:
Parent Graph: f(x) = a(bx - h)² + k
a is vertical shrink/stretch
b is horizontal shrink/stretch
h is horizontal movement left/right
k is vertical movement up/down
h, k is vertex
Step 1: Define variables
h = -3
k = 0
a = 2
Step 2: Write quadratic
f(x) = 2(x + 3)²
f(x) = x^2 x+1
g(x)= 2x-5

Sally is having a party and she has invited nine of her friends.
She is going to make a special non-alcoholic fruit punch for them all
to drink. Sally wants to make enough fruit punch for herself
and all her friends to have one glass each.
Sallys Fruit Punch Recipe.
The recipe below makes enough
fruit punch for 1 person.
1/2 lime
1/2 lemon
100ml pineapple juice 200ml lemonade 100ml orange juice
1) How much of each ingredient will she need?
Limes
Lemons Pineapple juice Lemonade Orange juice
Cost of ingredients:
Pineapple Juice
Lemons 50 each
Limes 40c each
Lemonade (2 liter bottle) $1.60
Orange juice (1 liter carton) 80c
Pineapoe juice (1 liter carton) 90c
Answer:
1) 5 limes, 5 lemons, 1,000 mL of pineapple juice, 2,000 mL of lemonade, 1,000 of orange juice
2) Limes = $2, Lemons = $2.5, Lemonade = $1.60, Orange Juice = 80c, Pineapple Juice = 90c
Step-by-step explanation:
1/2 limes · 10 = 5
1/2 lemons · 10 = 5
100 mL of pineapple juice · 10 = 1,000 mL
200 mL of lemonade · 10 = 2,000 mL
100 mL of orange juice · 10 = 1,000 mL
Cost:
5 limes · 0.4 = $2
5 lemons · 0.5 = $2.5
mL to L
1,000 mL of pineapple juice = 1 L, this costs 90¢
2,000 mL of lemonade = 2 L, this costs $1.60
1,000 mL of orange juice = 1 L, this costs 80¢
Overall:
5 limes for $2
5 lemons for $2.5
1 L of of pineapple juice for 90¢
2 L of lemonade for $1.60
1 L of orange juice for 80¢
Explain why the graph of the equation g(x)=-(x+1)^2-3 would be a parabola opening downward.
The parabola opens downwards since a=____ and this value is _____ 0.
The choices for the second blank question are:
-less than
-greater than
-equal to
g(x) = -(x + 1)^2 - 3
Let's simplify this equation
g(x) = -(x^2 + 2x + 1) - 3
Distribute the negative sign
g(x) = -x^2 - 2x + 1 - 3
Combine like terms
g(x) = -x^2 - 2x - 2
The value of a = -2 and this value is LESS THAN 0
(0.4y - 3)/(1.5y + 9) = -7/5
