here are the score that Jenna has received on her seven quizzes 16 13 20 16 12 17 18 what is the mean
Answer:
so you're adding up all the numbers together so 16+13+20+16+12+17+18=112
then you are dividing it by how many numbers there are so there are 7 numbers in total 112÷7=16
A fireworks rocket is launched from a hill above a lake. The rocket will fall into the lake after
exploding at its maximum height. The rocket's height above the surface of the lake is given by g(x)=
-16x² + 64x + 80. What is the maximum height of the rocket?
Answer:
(2,114)
Step-by-step explanation:
g(x)= -16x² + 64x + 80
Plug 2 in to check if it's correct.
g(2)= -16(2)² + 64(2) + 80
-16(4)+128+80
-64+128+80
= 144
Answer:
144
Step-by-step explanation:
Does anyone know the correct answer for this!?!!
Answer:
2
Step-by-step explanation:
Use the vertex form equation first since you are given the vertex (-1,-2) where you have (h,k) so h = -1 and k = -2
y = [tex]a (x - -1)^{2}[/tex] + (-2) so if you simplify we get y = a(x+1)^2 -2
Since we are also given a point we can solve for a so x = 2 and y = 16
16 = a(2+1)^2 - 2
16 = a(3)^2 - 2
18 = 9a
a = 2
help pls !! will mark brainliest !!
Answer:
y = 21
Step-by-step explanation:
(3y-8) = 55 (corresponding angles are equal)
3y-8 = 55 (add 8 from both sides)
3y = 63 (divide 3 from both sides to isolate the y variable)
y = 21 (final answer)
Answer:
y = 21
Step-by-step explanation:
X, Y and Z are three points on a map. Y is 43km and on a bearing of 041° from X. Z is 67km and on a bearing of 117° from X. Calculate the distance between Y and Z rounded to 1 DP
Answer:
70.3km
Step-by-step explanation:
When the bearings are visualized and the points connected as a triangle, The angle x would be the difference of the both bearings from x
i.e 117-41 = 76
Using cosine rule,
YZ²= 43² + 67² - 2 x 43 x 67
cos76
YZ= √4944
= 70.3

Charlotte borrows $9000 to buy a second-hand car. The loan must be repaid
over 5 years at 12% p.a. simple interest. Calculate the
total amount to be repaid
Answer:
$13,400
Step-by-step explanation:
Simple Interest = principal × rate × time
principal= $9000
Rate= 12/100=0•12
Time=5years
Simple interest =PRT
= 9000× 0•12 × 5
= 5400
Total amount to be paid = 9000 + 5400
= $13400

An aquarium has 14 angel fish, 12
clownfish and 18 seahorses. What is the
ratio of seahorses to total number of fish?
Answer:
18 : 26
Step-by-step explanation:
It is very easy, angel fish and clown fish are fish, so once you add them up you get 26. The seahorses are 18 and we are supposed to make them S:F. Therefore you put the seahorses first and the fish second, so you get the answer 18:26
Find the slope and the y-intercept of the line.
5x-4y=-8
Write your answers in simplest form.
Answer:
The slope is 5/4 and the y-intercept is 2.
Step-by-step explanation:
5x-4y=-8
4y=5x-(-8)
4y=5x+8
y=5/4x+8/4
y=5/4x+2
y=mx+b where m=slope and b=y-intercept.
Ron made 3 pitchers of lemonade sell at a lemonade stand. The cost of making the lemonade is 50 cents per pitcher of lemonade.
He sold each cup of lemonade for 15 cents, and he sold a total of 36 cups of lemonade.
How much money did Ron make selling lemonade after paying out the cost of making the lemonade?
Answer:
Step-by-step explanation:
cost = 3 pitchers × $0.50/pitcher = $1.50
revenue = 36 cups × $0.15/cup = $5.40
profit = $5.40 - $1.50 = $3.90
Gabriel took a bath on Monday evening. He measured the water and found that he used 1,235l of water. On Tuesday, he took a shower and only used 478 litres of water. What was the difference in volumes? How much water did he used in total?
Answer:a)757liters
b)1, 713 litres
Step-by-step explanation:
Amount of water used on Monday =1,235l
Amount of water used on Tuesday =478liters
Difference in volumes for the two days
=1,235l -478l
=757liters.
Total amount of water used up in Total
1,235litres +478liters
=. 1, 713 litres.

The population of cats in a town increased by 25% from Year 1 to Year 2. The population of cats in Year 2 is 60.
Answer: See explanation
Step-by-step explanation:
Your question isn't complete but I guess that you want to find the population of the cats in Year 1. This will be represented by x. Therefore,
x + (25% × x) = 60
x + (0.25 × x) = 60
x + 0.25x = 60
1.25x = 60
x = 60/1.25
x = 48
The population of cats in year 1 is 48

A. The data represent an exponential function because there is a
common ratio of 4.
B. The data represent a linear function because there is a common
difference of 9
C. The data represent an exponential function because there is a
5
common ratio of -
D. The data represent a linear function because there is a common
difference of -9.
Answer:-8
Step-by-step explanation:
The data represent a linear function because there is a common difference of -9.
What is a linear function?The term linear function refers to two distinct but related notions: In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.
Given, the table, we need to see whether the data in the table represent a linear function or an exponential function.
From the table, we have the following highlight :-
As the values of x increase by 1, the values of y decrease by 9
A decrement of 9, means -9
This means that, the common difference is -9.
Only a linear function can have a common difference.
Hence, the true statement is (b)
