The average winter temperature at the South Pole is -49 degrees Celsius. The coldest temperature recorded in Antarctica was 40.6 degrees Celsius colder than the average winter temperature at the South Pole. What was the coldest recorded temperature in Antarctica?
Answer:
The coldest temperature at Antarctica is -89.6 degrees celsius
Step-by-step explanation:
Here, we are interested in calculating the coldest temperature in Antarctica.
In the question, we are simply told that the coldest Antarctica temperature was 40.6 colder than the average winter temperature at the south pole.
The average winter temperature at south pole = -49 degree celsius
The coldest temperature is thus -49-40.6 = -89.6 degrees celsius

3. A water balloon was thrown
from a window. The height
of the water balloon over
time can be modeled by the
function y= 16x2 + 160x + 50.
What was the maximum
height of the water balloon
after it was thrown?
Note: It the given equation the coefficient of [tex]x^2[/tex] must be -16 instead of 16.
Given:
Consider the height of the water balloon over time can be modeled by the function
[tex]y=-16x^2+160x+50[/tex]
To find:
The maximum height of the water balloon after it was thrown.
Solution:
We have,
[tex]y=-16x^2+160x+50[/tex]
Here, leading coefficient is negative. So, it is a downward parabola and vertex of a downward parabola, is the point of maxima.
If a parabola is [tex]f(x)=ax^2+bx+c[/tex], then
[tex]Vertex=\left(-\dfrac{b}{2a},f(-\dfrac{b}{2a})\right)[/tex]
Here, [tex]a=-16,b=160,c=50[/tex]. So,
[tex]-\dfrac{b}{2a}=-\dfrac{160}{2(-16)}[/tex]
[tex]-\dfrac{b}{2a}=-\dfrac{160}{-32}[/tex]
[tex]-\dfrac{b}{2a}=5[/tex]
Now, put x=5 in the given equation.
[tex]y=-16(5)^2+160(5)+50[/tex]
[tex]y=-16(25)+800+50[/tex]
[tex]y=-400+850[/tex]
[tex]y=450[/tex]
The vertex of the given parabolic equation is (5,450).
Therefore, the maximum height of the balloon is 450 units after 5 units of time.

Height of Tree (inches)
The graph shows the growth of a tree, with x
representing the number of years since it was planted,
and y representing the tree's height (in inches). Use
the graph to analyze the tree's growth. Select all that
apply.
The tree was 40 inches tall when planted.
The tree's growth rate is 10 inches per year.
The tree was 2 years old when planted.
As it ages, the tree's growth rate slows.

Years since Planting Tree
Answer:
The tree was 40 in tall when planted
The tree's growth rate is 10in per year
Ten years after Planting, it is 140 inches tall
Step-by-step explanation:
original(slope intercept form) : y = 10x + 40
y = 10(10) + 40
y = 100 + 40
y = 40
x-y=11 2x+y=19 elimantion
Answer:
x=20/3 y=17/3
Step-by-step explanation:
1. x-y=1
2. 2x+y=19
The first equation can be rewritten as 2x-2y=2
We can then subtract the second equation from this:
2x-2y=2
2x+y=19
-3y=-17
y=17/3
Plug this into to solve for x:
x-17/3=1
x=17/3+1
x=20/3

kostas gets a four year bank loan to buy a new car that is priced at 20,987. after four years Kostas Will have paid the bank it’s total of $22,960. what interest rate did the bank give him if the interest was compounded monthly. Show your work .
Answer:
r = 2.04%
Step-by-step explanation:
r = n{(A/P)^1/nt - 1}
Where,
r = interest rate = ?
n = number of periods = 12
A = future value = $22,960
P = present value = $20,960
t = time = 4 years
r = n{(A/P)^1/nt - 1}
r = 12{(22,960/20,987)^1/12*4 - 1}
= 12{(1.09)^1/48 - 1}
= 12{(1.09)^0.02 - 1}
= 12 (1.0017 - 1)
= 12(0.0017)
= 0.0204
r = 0.0204 × 100
= 2.04%
r = 2.04%
Carolyn has 20 biscuits in a tin.
She has
12 plain biscuits
5 chocolate biscuits
3 ginger biscuits
Carolyn takes at random two biscuits from the tin.
Work out the probability that the two biscuits were not the same type.
4 Marks
Answer:
Approximately 58.4%
Step-by-step explanation:
The probability that they are different is the opposite of the probability that they are the same.
The probability that they are the same is:
P(plain, plain) = (12/20) (11/19) = 132 / 380
P(chocolate, chocolate) = (5/20) (4/19) = 20 / 380
P(currant, currant) = (3/20) (2/19) = 6 / 380
P(same) = 132/380 + 20/380 + 6/380
P(same) = 158/380
P(same) = 79/190
Therefore, the probability that they are different is:
P(different) = 1 − 79/
[tex]\frac{111}{190}[/tex] is the probability that the two biscuits were of not the same type.
What is Probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
According to question, Carolyn has 20 biscuits in a tin.
She has 12 plain biscuits, 5 chocolate biscuits and 3 ginger biscuits
Carolyn takes at random two biscuits from the tin.
We have to find out the probability that the two biscuits were of not the same type.
P(plain biscuit, plain biscuit) [tex]=(\frac{12}{20} )(\frac{11}{19} )=\frac{132}{380}[/tex]
P(chocolate biscuit, chocolate biscuit)[tex]=(\frac{5}{20})(\frac{4}{19} )=\frac{20}{380}[/tex]
P(ginger biscuit, ginger biscuit)[tex]=(\frac{3}{20}) (\frac{2}{19})=\frac{6}{380}[/tex]
Probability of same type of biscuits
[tex]=\frac{132}{380} +\frac{20}{380}+\frac{6}{380}[/tex]
[tex]=\frac{79}{190}[/tex]
The probability that the two biscuits were not of the same type.
[tex]=1-\frac{79}{190}[/tex]
[tex]=\frac{111}{190}[/tex]
Hence, we can conclude that [tex]\frac{111}{190}[/tex] is the probability that the two biscuits were not of the same type.

Step-by-step explanation:
Let U = {9, 10, 11, 12, 13, 14} and A = {11, 13}. Determine whether the statement A⊂U is true or false and find A'.
a. false; A' = {11, 12, 13, 14}
b. true; A' = {9, 10, 11, 12, 14}
c. false; A' = {9, 12, 14}
d. true; A' = {9, 10, 12, 14}
Answer:
D; A⊂U is true and A'={9, 10, 12, 14}
Step-by-step explanation:
A={11,13}
Because those numbers are included in the statement U={9,10,11,12,13,14}, we can say that it's true that A belongs to U.
A' is the numbers of U not including A. So, it would just be U without the 11 and 13, or {9,10,11,12}

What is -5n+7<57 and 6n+2<8
Answer:
if -5n+7<57, then n>-10.
if 6n+2<8, then n<1.
Step-by-step explanation:
-5n+7<57
1. subtract 7 from both sides:
-5n+7 -7< 57 -7
-5n<50
2. divide both sides by -5 (remember to flip the sign whenever you divide by a negative number):
-5n ÷-5<50 ÷-5
n>-10
6n+2<8
1. subtract 2 from both sides:
6n+2 -2<8 -2
6n<6
2. divide both sides by 6:
6n ÷6<6 ÷6
n<1

What is Number Line?Number line is defined as the straight line drawn horizontally where the integers are placed at an equally spaced way.
Integers includes natural numbers, 0 and negative of the natural numbers.
Given is the three numbers 5, -2 and -1.
We have to find the product of these three numbers.
When multiplying integers, negative multiplied to negative and positive multiplied to positive gives positive. If one of the number is negative and other is positive, then the result is negative.
(5) (-2) (-1) = (5 × -2) (-1)
= (-10) (-1)
= 10
Hence the product of the three integers 5, -2 and -1 is 10 which is marked as point D on the number line.
