Answer:
(First of all its 20 points not 40 but any ways) A ferris wheel has a raidus of 20 m. Passengers get on halfway up on the right side. The direction of rotation is counter clockwise. The bottom of the ferris wheel is 2 m above ground. It rotates every 36 seconds. Determine height above the ground after 15 seconds algebraically. Determine seconds to the nearest tenth when height is 38 m above the ground algebraically.
**
let t=seconds after wheel starts to rotate.
let h=meters above ground after wheel starts to rotate
..
The formula I got: h(t)=20sin(πt/18)+22
This is close to the formula you got, except I left the negative sign out since passengers start to rise after the wheel starts going counter-clockwise.
..
After 15 seconds:
h=20sin(15π/18)+22
=20sin(5π/6)+22
=20*(1/2)+22
=32 m
..
When h=38 m
38=20sin(πt/18)+22
38-22=20sin(πt/18)
20sin(πt/18)=16
sin(πt/18)=16/20=4/5=.8
arcsin(.8)=0.927
πt/18=0.927 (radians)
t=(.927*18)/π≈5.31
..
height above the ground after 15 seconds≈38 m
seconds elapsed when height is 38 m above ground≈5.3 seconds

Ten cards numbered 1 through 10 are mixed together and then one card is drawn. Find the probability of each event. Write each answer as a fraction, percent, and decimal. P(less than 5) P(greater than 3) P(odd) P(even) P(not a multiple of 4) P(not 5, 6, 7, or 8) P(divisible by 3)
Answer:
2/5, 0.4, 40%
7/10, 0.7, 70%
1/2, 0.5, 50%
1/2, 0.5, 50%
4/5, 0.8, 80%
3/5, 0.6, 60%
3/10, 0.3 ; 30%
Step-by-step explanation:
Sample space = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
P(less Than 5) :
Required = (1, 2, 3, 4) = 4 observations
P(less than 5) = 4 / 10 = 2 / 5 = 0.4 = 40%
Greater than 3) = (4, 5,6,7,8,9,10) = 7 observations
P greater Than 3) = 7/10 = 0.7 = 70%
Odd = (1,3,5,7,9) = 5
P(odd) = 5 / 10 = 1/2 = 0.5 = 50%
(even) = (2,4,6,8,10) = 5
P(even) = 5 / 10 = 1/2 = 0.5 = 50%
Not a multiple of 4 = (1,2, 3,5,6,7,9,10) = 8
P(not A multiple of 4) = 8/10 = 4/5 = 0.8 = 80%
not 5, 6, 7, or 8 = (1,2,2,4,9,10).= 6
P(not 5, 6, 7, or 8) = 6 / 10 = 3/5 = 0.6 = 60%
Divisible by 3 = (3, 6, 9) = 3
P(divisible by 3). = 3/10 = 0.3 = 30%
Can anyone help with this problem??
Answer:
blue line : y = 3
black horizontal line : y = 0
black vertical line : x = 0
Step-by-step explanation:
it is really simple.
blue line : no matter what value we pick for x, the functional value for y is always 3. and that defines the equation y = 3 + 0*x or simply y = 3.
the same with the black horizontal line. the difference is that y is now always 0. so, y = 0.

Some for all values of x by factoring
Answer:
{-1, 10}
Step-by-step explanation:
Next time please share the entire set of instrutions.
x^2 - 9x - 15 = -5 should be rewritten in standard quadratic form:
x^2 - 9x - 10 = 0 = (x - 10)(x + 1) = 0.
Setting each factor equal to zero and then solving for x yields {-1, 10}
Answer:
{-1,10}
Step-by-step explanation:
[tex]x^2-9x-15=-5[/tex] given
[tex]x^2-9x-10=0[/tex] addition property of equality
[tex]x^2+(x-10x)-10=x^2+x-10x-10=0[/tex] x-10x = -9x
[tex]x(x+1)-10(x+1)=0[/tex] distributive property ( x( y + z ) = xy + xz
[tex](x-10)(x+1)=0[/tex] distributive property (backwards)
[tex]x-10=0;x=10;x+1=0;x=-1[/tex] at least one factor of 0 has to be 0
{-1,10}

aria and her two friends met up for dinner. They want to split the cost of dinner evenly between the friends but first had to get the total after adding the tax and tip. Their bill is shown below. The sales tax at this location of Sam’s World is 7.75%. They agreed to leave an 20% tip. The tip is added to the total after the sales tax is added.
The total is 38.96
Estimate the approximate total cost of the bill including tax and tip to the nearest dollar.
A
$50.38
B
$41.98
C
$38.96
D
$8.40
PLEASE HELp
Answer:
A. 50.38
Step-by-step explanation:
Bill is 38.96. Calculate sales tax: 38.96x.0775=3.02.
38.96 + 3.02=41.98 total before tip
41.98x.20=8.40 tip
41.98 + 8.40=50.38

A new school is ordering math textbooks. They are 3/4 of an inch thick. How many of these books will fit into a bookshelf that is 2 feet long?
A) 2 books
B) 12 books
C) 26 books
D) 32 books
Answer:
32 Books
Step-by-step explanation:
You know that the bookshelf is 2 feet long, and you know the book is 3/4 inches thick. To start you have to get a common measurement in this case we will use inches. You already know that 1 foot is 12 inches so 2 feet will be 24 inches. Next all you do is divide the 24 inches by 3/4 inches. This will give you 32 which is the total amount of books that can fit on the bookshelf.
Landon earns 10% commission on his total sales. What must be his total sales in oder to earn a commission of $ 145?
Answer: [tex]\$1450[/tex]
Step-by-step explanation:
Given
Landon earns a 10% commission on his total sales
Suppose his total sales is x to get a commission of $145 i.e.
[tex]\Rightarrow x\times 10\%=145\\\Rightarrow 0.1x=145\\\Rightarrow x=\$1450[/tex]
Therefore, the amount of total sales must be $1450

Answer:
y=-6/5x -8
Step-by-step explanation:
slope is the same as gradient(m) so find the c in the equation y=mx+c using the point (-5,-2) which gives u -8 then substitute values of m and c in that very equation
Answer:
[tex]y=-\frac{6}{5}x-8[/tex]
Step-by-step explanation:
Same process as the other two lol
y= -(6/5)x+b
solve for b by plugging in the required coordinates
-2= -(6/5)(-5)+b
-2= 6+b
-8=b
put it all together

Hi there! We are given three functions below:
[tex] \large \boxed{f(x) = \frac{2 + {x}^{2} }{x + 6}} \\ \large \boxed{g(x) = \sqrt{1 + 7x} } \\ \large \boxed{h(x) = | \frac{3}{4} x - 14 | }[/tex]
Next, we are going to substitute the values that replace x-term. Substitute these values in each functions.
We are given below:
f(4)g(2)h(8)Therefore,
[tex] \large{f(4) = \frac{2 + {4}^{2} }{4 + 6} } \\ \large{g(2) = \sqrt{1 + 7(2)} } \\ \large{h(8) = | \frac{3}{4} (8) - 14}| [/tex]
Then evaluate the value.
[tex] \large{f(4) = \frac{2 + 16}{10} } \\ \large{g(2) = \sqrt{1 + 14} } \\ \large{h(8) = | 3(2) - 14}| [/tex]
[tex] \large{f(4) = \frac{18}{10} \longrightarrow \frac{9}{5} } \\ \large{g(2) = \sqrt{15} } \\ \large{h(8) = | 6- 14| \longrightarrow | - 8| = 8 }[/tex]
Answer
f(4) = 9/5g(2) = sqrt(15)h(8) = 8Given
mZLON is a straight angle.
MZLOM = 4x + 30°
mZMON = 8x + 90°
Find mZMON:
Help pls
Step-by-step explanation:
these are supplementary angles
LOM + MON = 180
(4x + 30) + 8x + 90 = 180
12x + 120 = 180
solve for x and then substitute into 8x +90
