Function NotationStep-by-step explanation:
Step 1: Define
f(x) = 2/3x² + 8
f(6) is x = 6
Step 2: Evaluate
Substitute in x: f(6) = 2/3(6)² + 8Exponents: f(6) = 2/3(36) + 8Multiply: f(6) = 24 + 8Add: f(6) = 32Answer:
f(6)= 72
Step-by-step explanation:
f(6)= 72
to evaluate:
substitute x = 6 into
f(x)f(6)= 23 × (6) 2 + (8×6)×x = 231 × 3612+ 48

How many solutions does 5(x+9)=5x+45 have
Answer:
Simplifying
5(x + 9) = 5x + 45
Reorder the terms:
5(9 + x) = 5x + 45
(9 * 5 + x * 5) = 5x + 45
(45 + 5x) = 5x + 45
Reorder the terms:
45 + 5x = 45 + 5x
Add '-45' to each side of the equation.
45 + -45 + 5x = 45 + -45 + 5x
Combine like terms: 45 + -45 = 0
0 + 5x = 45 + -45 + 5x
5x = 45 + -45 + 5x
Combine like terms: 45 + -45 = 0
5x = 0 + 5x
5x = 5x
Add '-5x' to each side of the equation.
5x + -5x = 5x + -5x
Combine like terms: 5x + -5x = 0
0 = 5x + -5x
Combine like terms: 5x + -5x = 0
0 = 0
Solving
0 = 0

C50
D40
Answer:
B. 140
Step-by-step explanation:
With this chart, you must know the fundamentals of the angles. In this case, angle c and e are supposed to equal to 180. In the question, it gives us both the formulas for both angles. So adding them up to 180 will give us x
(x - 10) + (2x + 40)
with a trusty calculator, you will get
= 3x + 30
Now equal this equation to 180
3x + 30 = 180
3x = 180 - 30
3x = 150
Now divide 150 to 3
150 divided by 3 = 50
x = 50
Now just add the x to the angle c
2(50) + 40
=140
To further check if its correct, add the x to angle e
(50) - 10
=40
140 +40 = 180
So the answer would be 140

Water runs from a pump at a rate of 0.5 gallons per minute. At this rate, how long would it take to fill a tub with a 150-gallon capacity?
Answer:
300 min or 5 hours
Step-by-step explanation:
so if it pumps 0.5 gallons per minute than in 2 minutes it would pump 1 whole gallon so with that we know 1gallon=2 minutes.
so with that we multipy both sides by 150 which will be 150 galons=300 minutes or 5 hours

The table shown the number of campers, x, at a local campsite and the total amount of money, y, in dollars, earned by the camp site.
To find:
The unit for the rate of change.
Solution:
We know that, rate of change is the change in y-values with respect to x-values, i.e.,
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
In the given problem, y is the total earnings in dollars and x is the number of campers. So, the rate of change represents the change is earnings with respect to number of campers.
Thus, the unit of rate of change is dollars per camper.
Therefore, the correct option is D.
Jeff is lining up children and adults bicycle at bike shop where he work the children bicycle is nine less three times the number of adult bicycle there are 42adult bicycle how many child
ren bike are there
Answer:
Number of children bicycles = 117
Step-by-step explanation:
Given that:
Number of adult bicycles = a = 42
Let,
x represent the number of children bicycle
According to given statement;
The number of children bicycle is nine less three times the number of adult bicycles.
x = 3a - 9
Putting a=42
x = 3(42)-9
x = 126-9
x = 117
Hence,
Number of children bicycles = 117

Ben saved 172 coins. He saved nickels and dimes only. If he had $14, how many nickels did he have?
Answer:
64 Nickels
Step-by-step explanation:
172 coins equal $14.00
It took time to figure this out, I just used a calculator to shimmy down the gap of possibilities, starting here;
100d = $10.00
72n = $3.60
I got closer here;
110d = $11.00
62n =$3.10
I subtracted 2 dimes and added 2 nickels from the previous to get the answer.
108d = $10.80
64n = $3.20
$10.80 + $3.20 = $14.00

A ball is dropped from a height of 1m. The ball bounces and rebounds, losing 14% of its previous height and then falls again. If the ball continues to rebound and fall in this manner, find the total vertical distance the ball travels until it hits the ground for the 6th time.
9514 1404 393
Answer:
7.51 m
Step-by-step explanation:
The distance traveled to the first floor hit is 1 m. The next hit has a height that is 14% less, so is 100% -14% = 86% = 0.86 times this height. The travel up and down to/from that height is added to the total.
The distance traveled to the second floor hit is 1 m + 2×(0.86×1 m).
The distance traveled to the third floor hit is 1 m + 0.86×2 m + 0.86²×2 m.
Then the distance traveled to the n-th floor hit is ...
-1 m + Sum(0.86^k × 2 m) for k = 0 to n-1
The sum can be found from the formula for the sum of a geometric series:
Sn = a1×(r^n -1)/(r-1) . . . . . where a1 is the first term and r is the common ratio.
For r = 0.86, n = 6, and a1 = (2m), the total distance is ...
vertical distance = -1 m + (2 m)(0.86^6 -1)/(0.86 -1)
= -1 m + (2 m)(-0.5954)/(-0.14) ≈ 7.5062 m
The total distance traveled to the 6th floor hit is about 7.51 meters.

The 3 x 5 matrix shows the number of sandwiches sold over five days at the school canteen.

Answer:
a. 48 salads were bought on Wednesday
b. 42 chickens were bought on Thursday
c. 39 cheese were bought on Friday
Step-by-step explanation:
Given
[tex]------- M -- T - W -- T -- F[/tex]
Cheese ----- 50 -- 45 - 52 - 47 --39
Salad -------- 61 -- 44 - - 48 - 38 -- 51
Chicken ---- 53 -- 46 - - 39 - 42 -- 52
First, it should be noted that the horizontal data represent the row while the vertical data represent the column.
Having said that, the solution is as follows:
Solving (a): Second Row, Third column
The data at the second row are:
[tex]------- M -- T - W -- T -- F[/tex]
Salad -------- 61 -- 44 - - 48 - 38 -- 51
The data at the third column is then limited to:
------------------W
Salad -------- 48
So the number at this position implies that: 48 salads were bought on Wednesday
Solving (b): Third Row, Fourth column
The data at the second row are:
[tex]------- M -- T - W -- T -- F[/tex]
Chicken ---- 53 -- 46 - - 39 - 42 -- 52
The data at the fourth column is then limited to:
------------------- T
Chicken ---- 42
So the number at this position implies that: 42 chickens were bought on Thursday
Solving (c): First Row, Fifth column
The data at the first row are:
[tex]------- M -- T - W -- T -- F[/tex]
Cheese ----- 50 -- 45 - 52 - 47 --39
The data at the fifth column is then limited to:
------------------F
Cheese ----- 39
So the number at this position implies that: 39 cheese were bought on Friday
1. Given the production function: Q = A L½ K½ What returns to scale, does this function exhibit? Why?
Answer:
a. This function therefore exhibits a constant return to scale.
b. The reason is that the sum of the exponents of the multiplicative factor a is equal to 1.
Step-by-step explanation:
The given production function is first correctly stated as follows:
Q = A L^½ K^½ .......................... (1)
In order to know the returns to scale this function exhibits, the input K and L are scaled by the multiplicative factor a which is included in equation (1) as follows:
Q = A (aL)^½ (aK)^½
Q = A a^½L^½ a^½K^½
Q = A a^½ a^½ L^½ K^½
Q = A a^(½+½) L^½ K^½
Q = A a^1 L^½ K^½ ......................... (2)
Based on the equation (2), we now answer the following questions:
a. What returns to scale, does this function exhibit?
This function therefore exhibits a constant return to scale.
b. Why?
The reason is that the sum of the exponents of the multiplicative factor a in equation (2) is equal to 1.
