Answer:
3/5
Step-by-step explanation:
sin is opposite over hypotenuse
find hypotenuse first -> Hypotenuse = 100 m
(notice that it is a 3-4-5 triangle)
60/100 = 6/10 = 3/5
Write the sum using summation notation, assuming the suggested pattern continues. -3+6+15+24+...+132
Answer:
Option (4)
Step-by-step explanation:
Given sequence is,
-3 + 6 + 15 + 24 + ........+ 132
Difference in 1st and 2nd term = 6 - (-3)
= 9
Difference in 2nd and 3rd term = 15 - 6
= 9
There is a common difference of 9 in each successive term.
Therefore, it's an arithmetic sequence.
Let the nth term of this sequence is (a + bn).
For the first term → n = 0,
a = -3
For second term → n = 1
-3 + b(1) = 6
b = 6 + 3
b = 9
Therefore, nth term of the sequence will be,
[tex]T_n[/tex] = -3 + 9n
For nth term = 132
-3 + 9n = 132
9n = 135
n = [tex]\frac{135}{9}[/tex]
n = 15
Sum of 15 terms can be represented by the expression;
[tex]\sum_{n=0}^{15}(-3+9n)[/tex]
Option (4) is the answer.

Activity
On the way home from visiting his family, Vincent's plane cruised at an altitude of 3.2 x 104 feet. He had heard that a man named Felix
Baumgartner skydived from an altitude of 1.28 x 10$ feet. Vincent wants to know how much higher Felix went on his skydiving trip.
write the cruising altitude of vincent’s plane in standard notation
Answer:
Vincent’s plane is cruising at an altitude of 3.2 × 10^4 feet.
Convert the number to standard notation.
3.2 × 10^4 feet
=
3.2 • 10,000 feet
=
32,000 feet
Step-by-step explanation:
This is the sample answer from Edmentum.
Answer:
Question 1 part a =
Vincent’s plane is cruising at an altitude of 3.2 × 104 feet.
Convert the number to standard notation.
3.2 × 104 feet
= 3.2 • 10,000 feet
= 32,000 feet
Part b =
Felix’s skydiving altitude is 1.28 × 105 feet.
Convert the number to standard notation.
1.28 × 105 feet
= 1.28 • 100,000
= 128,000 feet
Part c =
Subtract the two altitudes to find the difference.
128,000 feet − 32,000 feet = 96,000 feet
The difference of their altitudes is 96,000 feet.
Part d =
The difference of the altitudes is 96,000 feet.
Covert 96,000 to scientific notation:
96,000 feet = 9.6 × 104 feet
Question 2 part a =
Vincent’s plane’s altitude is 3.2 x 10^4 feet.
Felix’s skydiving altitude is 1.28 x 10^5 feet.
Transform 3.2 x 10^4 so its exponent matches the power of 10 in 1.28 x 10^5.
To do so, multiply and divide the number by 10.
3.2 x 10^4 = 10/10 x 3.2 x 10^4
= 3.2/10 x 10^4 x 10
= 0.32 x 10^5
Part b =
Calculate the difference of the two altitudes:
1.28 × 105 – 0.32 × 105
= (1.28 – 0.32) • 105
= 0.96 • 105
The difference of their altitudes is 0.96 •105 feet.
Part c =
The difference of Vincent’s and Felix’s altitudes is 0.96 x 10^5 feet.
To convert the answer to scientific notation, multiply and divide the number by 10.
0.96 x 10^5 = 10/10 x 0.96 x 10^5
= (0.96 x 10) x (10^5 x 10^-1)
= 9.6 x 10^4 feet
In scientific notation, the difference of Vincent’s and Felix’s altitudes is 9.6 x 10^4 feet.
Question 3 =
The altitudes are the same. That means you can subtract numbers given in scientific notation using either of two methods: convert them to standard notation and then perform the subtraction, or subtract the numbers in scientific notation without converting them to standard notation.

8. David is having a Super Bowl party and he needs
bottled water. Which of the following purchases will give
him the lowest unit cost?
a) $1.80 for a 6 pack
b) $6.00 for a 24 pack
c) $4.80 for a 12 pack
d) $10.00 for a 36 pack
Answer:
D) 10.00 for a 36 pack
Step-by-step explanation:
(I'm going up by the smallest pack to the highest because I noticed they are all multiples of 6)
1.80 for a 6 pack (double it to become a 12 pack)
3.60 for a 12 pack but the other 12 pack is more expensive making a 6 pack cheaper. (add another 6 pack)
5.40 for a 18 pack (add another 6pack)
7.20 for a 24 pack so this means the 6pack is more expensive and a 24pack is cheaper (in gonna keep adding till we get to 36 pack)
9 for a 30 pack
10.80 for a 36 pack

0.43 x 100 = 43%
1.8y-9.3y-6.3y I don't get it
Answer:
-13.8y
Step-by-step explanation:
Since these all have the same variable you don't need to worry that much. Let's take away the y to make it easier. Now you just subtract normally.
1.8 - 9.3
A trick that I use is that I subtract 9.3 - 1.8, and then add a negative sign. So that is -7.5
Then, subtract -7.5-6.3. You add these because they have the same symbol. So it is -13.8
We can't forget about the variable!! So it is -13.8y
Hope this helps!!

Please could someone help me with this
pls help will give brainlist
Answer:
x = 3
y = 2
Step-by-step explanation:
5x + 4y= 23
x - y = 1 then x = y + 1
substitute for x:
5(y + 1) + 4y = 23
simplify:
9y = 18
y = 2
x = 2 + 1 = 3
check:
3-2 = 1
1 = 1
and:
5(3) + 4(2) = 23
23 = 23

Re-write the quadratic function below in standard form y=3(x+4)(x+1)
Answer:
y = 3x² + 15x + 12
Step-by-step explanation:
A quadratic function in standard form is
y = ax² + bx + c ( a ≠ 0 )
Given
y = 3(x + 4)(x + 1) ← expand the factors using FOIL
= 3(x² + 5x + 4) ← distribute parenthesis by 3
= 3x² + 15x + 12

There are 101 Year 13 pupils in a tennis club, out of a total of 146 pupils. Write this proportion as a percentage. Give your answer correct to 1 decimal place when appropriate.
Answer: 69.2%
Step-by-step explanation:
There are 101 Year 13 students out of a total number of 146 pupils.
To find this as a percentage, divide the total number of students by the year 13 students and then multiply by 100%:
= Year 13 students/ Total students * 100%
= 101 / 146 * 100%
= 0.692 * 100%
= 69.2%

Which number is the same distance away from zero as is the number 4?
Answer:
25
Step-by-step explanation:
hopw this helps
Answer: That would be called absolute value (how far a number is from zero) so that means that it could be any number as long as the negative AND POSITIVE version of the number has lines on each side of it. In this case since you're using 4( which is positive) the answer would be -4( which is negative).
