Step-by-step explanation:
Figure is attached.
The distance the particle travels is the area under the v-t graph over the time interval from 0 min to 4 min. The reason you can't just multiply velocity by time is that the velocity is changing at a constant rate over the given time interval (the line is going upward--the particls is speeding up).
What's the area under the graph?
The red outline forms a trapezoid. The area of a trapezoid is [tex]A=\frac{1}{2}h(b_1+b_2)[/tex] where the b's are the lengths of the two parallel base and h is the height (the distance between the bases).
Reading the graph carefully (notice the scales!)...
[tex]A=\frac{1}{2}(4)(30+90)=(2)(120)=240 \text{m}[/tex]

an umbrella has 12 evenly spaced ribs. If viewed as a flat circle of radius 11 units,
then what would be the area between two consecutive ribs of the umbrella
Answers
Answer:
Area = 121pi/12
~= 31.66 sq units
Step-by-step explanation:
They are talking about looking at an umbrella like its a circle. The radius is 11 units. That is from the center to the edge.
Consecutive means "in a row" or "next to each other" The 12 "ribs" are the like skeleton structure in the umbrella. But they cut the umbrella into 12 areas. They are asking for the area of one "slice". It is 1/12 of the area of the whole circle.
Area of a circle is
A = pi × r^2
Area of one slice is 1/12 of the whole.
A(1 slice)
= 1/12× pi × r^2

Answer:
3x
Step-by-step explanation:
Since k(x)=27x^3, we replace it in h( k(x) ), we will get:
h(27x^3)
Given that h(x)={3}√x [my keyboard doesn't support cubic root]
= {3}√(27x^3)
27 is 3^3,
Simplifying, the final answer is:
3x.
Answer:
3x
Step-by-step explanation:
[tex]h(x) = \sqrt[3]{x},\: \: k(x) = 27 {x}^{3} \\ \\ (a) \: h(k(x)) = \sqrt[3]{27 {x}^{3} } \\ \\ = \sqrt[3]{ {(3x)}^{3} } \\ \\ = {(3x)}^{3 \times \frac{1}{3} } \\ \\ = 3x[/tex]

Input values 0 and 50 for x in the function f(x) - 4x + 5
Solve:
f(0) = 4(0) + 5f(0) = 0 + 5f(0) = 5f(50) = 4(50) + 5f(50) = 200 + 5f(50) = 205The range is between these two points: 5 ≤ y ≤ 205

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).
15,9, 5/27, ...
Find the 10th term.
Answers
Step-by-step explanation:
the introduction of a fraction tells us that we are dealing with multiplications, and therefore a geometric sequence (where every new term is created by multiplying the previous term by a constant factor, the ratio r).
I think your teacher made a mistake, or you made one when typing the question in here.
there is no factor r that creates
15×r = 9
and
9×r = 5/27
it would mean that
15 × r² = 5/27
r² = 5/27 / 15 = 5/27 × 1/15 = 5/405 = 1/81
r = 1/9
but 15 × 1/9 = 5 × 1/3 = 5/3 is NOT 9
and 9 × 1/9 = 9/9 = 1 is NOT 5/27
so, this can't be right.
on the other hand
15 × r = 9
r = 9/15 = 3/5
and then
9 × 3/5 = 27/5
so, either the sequence should have been
15, 5/3, 5/27
or (and I suspect this to be true)
15, 9, 27/5
under that assumption we have
s1 = 15
r = 3/5
sn = sn-1 × r = s1 × r^(n-1) = 15 × (3/5)^(n-1)
s10 = 15 × (3/5)⁹ = 15 × 19683/1953125 =
= 3 × 19683/390625 = 59049/390625 =

80% of the astronomy club members own a telescope. If 20 students own a telescope, how many students are in the astronomy club in all?
Answers
Answer:
25 students
Step-by-step explanation:
Let x represent the amount of students in the astronomy club then:

Convert 80% to a fraction. Any percentage is that number over 100:
[tex]\frac{80}{100}x=20[/tex]
Simplify the fraction:
[tex]\frac{8}{10}x=20[/tex]
[tex]\frac{4}{5}x=20[/tex]
Multiply both sides by 5:

The expected value of the prize that will be awarded is $460.
What is expected value?The expected value (EV) is an anticipated average value for an investment at some point in the future. Investors use expected value to estimate.
here, we have,
to determine the expected value:
The expected value is calculated using:
E(x) = Σx * P(x)
So, we have:
E(x) = 100 *0.2 + 200 * 0.2 + 500 * 0.4 + 1000 * 0.2
Evaluate
E(x) = 460
Hence, the expected value of the prize that will be awarded is $460

Which statement best describes which plan Sun Valley High School should choose and why?
A) Adidas starts off being the better plan because they contribute more at the start, but Nike ends up giving twice as much money as Adidas.
B) Nike is the better plan because they end up giving more total money since they are doubling.
C) Adidas ends up with a total of $80, but Nike only contributes $64, so Adidas is the better plan.

Factors of a polynomial can divide it without leaving remainder. The other factor of [tex]6x^2 - 7x + 2[/tex] is given by Option D : [tex]3x + 2[/tex]
How to factorize a polynomial?Let the polynomial A(x) has one factor f(x).
Then, it means, we have:
[tex]\dfrac{A(x)}{f(x)} = g(x)[/tex]
Thus, A(x) can be written as [tex]A(x) = f(x) \times g(x)[/tex]
Thus, the other factor of that polynomial is
[tex]g(x) = \dfrac{A(x)}{f(x)}[/tex]
For given case, the polynomial [tex]A(x)[/tex] is
[tex]A(x) = 6x^2 - 7x + 2[/tex]
Its one factor f(x) is given [tex]f(x) = 2x - 1[/tex]
Thus, its second factor is obtained as:
[tex]g(x) = \dfrac{A(x)}{f(x)} = \dfrac{6x^2 - 7x + 2}{(2x - 1)} = \dfrac{6x^2 -4x -3x - 2}{2x - 1}\\\\g(x) = \dfrac{2x(3x + 2) - 1(3x + 2)}{2x - 1} = \dfrac{(2x - 1)(3x + 2)}{2x - 1}\\\\g(x) = (3x + 2)[/tex]
Thus, the second factor of the given polynomial is
