The fasted train in the world can travel 300 feet per second. How fast is this in miles per hour?
(1 mile = 5280 feet)
Answer:
205 miles per hour.
Step-by-step explanation:
1 mile = 5280 feet so:
300 ft / second = 300/ 5280 miles/second.
There are 3600 seconds in an hour so
this converts to 300 * 3600 / 5280 miles per hour
= 204.55 miles per hour.
Hey!

Is this statement true or false?
According to the graph, during periods of recession, the number of people in poverty increases.
True
False
Answer: The Statement is true
Step-by-step explanation: the lines in the graph are constantly parallel to each other, showing that when one increases, so does the other
Answer:
The given statement is true.
Step-by-step explanation:
We are given the following graph in the picture:
On the x-axis years are shown from 1959 to 2005.
The y axis shows the poverty rate and the number of people in poverty.
The blue strips in the graph are the recession time.
Now, for each blue strip, we could see the line for poverty rate and the number of people in poverty increases. There is an upward trend in the line in the blue strip.
In other words we could say that the slope increases for all the blue strips which actually represents that the number of people in poverty increases in recession.
Thus, the given statement is true.
what values of y will make the expression true? 10 - y = y - 10
Answer:
y = 10
Step-by-step explanation:
Given
10 - y = y - 10 ( subtract y from both sides )
10 - 2y = - 10 ( subtract 10 from both sides )
- 2y = - 20 ( divide both sides by - 2 )
y = 10

How many real solutions does the function shown on the graph have?
No real solutions
One real solution
Two real solutions
Cannot be determined
Answer:
0 because it doesn't cross the x-axis
Step-by-step explanation:
Interpreting the graph, it is found that the function has no real solutions.
The number of different real solutions that a function has is given by the number of times it crosses the x-axis(also known as the horizontal axis) on the graph.
In this problem, the function never crosses the x-axis, thus, it has zero real solutions.
A similar problem, in which the real solutions are taken from a graph, is given at https://brainly.com/question/16349072
What is the limit of the function?

for any positive value of "x" as it races off towards ∞, our first limit of -4x⁹ will give us a rather large negative value, our second limit of -3x³ will also give us a large negative value and both will combine to produce an even larger negative value.
our third limit of 2x will give us a positive value, however a much smaller than its previous siblings, and our last limit is just a fixed of -11, not moving at all.
since the negative values are moving faster than the positive ones, and thus overwhelming the positive ones, the limit will increasingly be racing towards -∞.
The limit of the function, [tex]\lim_{n \to \infty} f(x)= -4x^2 - 3x^3+2x - 11[/tex] is - ∞.
Here, given function is,
f(x)=−4x^9−3x^3+2x−11
We have to find the value of [tex]\lim_{n \to \infty} f(x)= -4x^2 - 3x^3+2x - 11[/tex].
What is limit of function?
Limit of function means the value towards which a function moves when the value of independent variable moves to infinity.
Now,
[tex]\lim_{n \to \infty} f(x)= -4x^2 - 3x^3+2x - 11[/tex]
[tex]\lim_{n \to \infty} f(x)= \lim_{n \to \infty} (-4x^2) - \lim_{n \to \infty} (3x^3) + \lim_{n \to \infty} 2x - \lim_{n \to \infty} 11[/tex]
[tex]\lim_{n \to \infty} f(x)= -[/tex]∞
Here, limit of [tex]-4x^{2}[/tex] is -∞, limit of [tex]-3x^{3}[/tex] is -∞ and limit of 2x is ∞.
For any positive value of x as it races off towards ∞ but here we find the limits as, -∞.
Since the negative values are moving faster than positive.
Hence, the limit will be towards -∞.

Which point is not on the graph of the function y = x + 5?
(2, 7)
(6, 11)
(220, 225)
(10, 5)
Answer:
(10, 5 )
Step-by-step explanation:
To determine which points lie on the graph or not.
Substitute the x- coordinate of the point into the equation and if the value agrees with the y- coordinate of the point then the point is on the graph.
(2, 7 )
y = 2 + 5 = 7 ← True thus point is on the graph
(6, 11 )
y = 6 + 5 = 11 ← True thus point is on the graph
(220, 225 )
y = 220 + 5 = 225 ← True thus point is on the graph
(10, 5 )
y = 10 + 5 = 15 ≠ 5 ← Point is not on the graph

Gary says that 3 - 1 1/3 will be more than 2, since 3 – 1 is 2. Draw a picture to prove that Gary is wrong.
Answer:
It makes 5/3 it is less than two!
Step-by-step explanation:
Topic: Fractions and Mixed Numbers
You have to remember the concept of fractions, let's represent by cake diagrams, it says that Gary says that 3, let's say it's 3 cakes, as the fractions are represented in terms of thirds, let's draw the cakes each one divided in 3.
and the statement says that taking away 1 and 1/3 it will make more than 2.
As you can see in the picture below, we take away 1 cake and we will take away another third of a second cake represented by the brown region of the cakes. it means that the yellow region is what's left after taking the 1 and 1/3. as you can see it doesn't make two, makes less than two exactly 5/3.

At a stock exchange there were a total of 10,000 shares sold in one day. Stock A had four times as many
shares sold as Stock B. The number of shares sold for Stock C was equal to the sum of the numbers of
shares sold for Stock A and Stock B. How many shares of each stock were sold?
shares of Stock A were sold,
were sold.
shares of Stock B were sold, and
shares of Stock
What’s the answer
Answer:
Share sold by Stock A = 4000, Stock B = 1000 and Stock C = 5000
Step-by-step explanation:
Total sold sold = 10000
i.e. [tex]A + B + C = 10000[/tex] ....(1)
Shares sold by stock A = 4 × Shares sold by stock B
i.e. [tex]A = 4B[/tex] ....(2)
Shares sold by stock C = Shares sold by stock A + Shares sold by stock B
i.e. [tex]C = A + B[/tex] ....(3)
substituting value of [tex]A[/tex] from (2) in (3) we get
[tex]C = 4B + B = 5B[/tex] ....(4)
substituting value of [tex]A[/tex] and [tex]C[/tex] from (2) and (4) in (1) we get
[tex]4B + B + 5B = 10000\\10B = 10000\\B = 1000[/tex]
[tex]A = 4B = 4*1000 = 4000[/tex]

Answer:
Part 1) 441km in 45s --> Has the same speed as Saige's spaceship
Part 2) 215km in 25s --> Does not have the same speed as Saige's spaceship
Part 3) 649km in 110s --> Does not have the same speed as Saige's spaceship
Step-by-step explanation:
The complete question is
Saige's spaceship traveled 588 kilometers in 60 seconds.
Determine whether or not each spaceship trip below has the same speed as Saige's spaceship.
441km in 45s
215km in 25s
649km in 110s
we know that
The speed is equal to divide the total distance traveled by the total time
In this problem we have that
The speed of Saiges spaceship is equal to
[tex]\frac{588}{60}=9.8\ \frac{km}{sec}[/tex]
case 1) we have
441km in 45s
Find out the speed of the spaceship trip
[tex]\frac{441}{45}=9.8\ \frac{km}{sec}[/tex]
Compare the speed of the spaceship trip with the speed of Saiges spaceship
[tex]9.8\ \frac{km}{sec}=9.8\ \frac{km}{sec}[/tex]
therefore
Has the same speed as Saige's spaceship
case 2) we have
215km in 25
s
Find out the speed of the spaceship trip
[tex]\frac{215}{25}=8.6\ \frac{km}{sec}[/tex]
Compare the speed of the spaceship trip with the speed of Saiges spaceship
[tex]8.6\ \frac{km}{sec}\neq 9.8\ \frac{km}{sec}[/tex]
therefore
Does not have the same speed as Saige's spaceship
case 3) we have
649km in 110s
Find out the speed of the spaceship trip
[tex]\frac{649}{110}=5.9\ \frac{km}{sec}[/tex]
Compare the speed of the spaceship trip with the speed of Saiges spaceship
[tex]5.9\ \frac{km}{sec}\neq 9.8\ \frac{km}{sec}[/tex]
therefore
Does not have the same speed as Saige's spaceship

Final answer:
[tex]9 \times 10^{-2 }(0.09)[/tex] is greater than [tex]3 \times 10^{-4} (0.0003)[/tex], and is 300 times greater.
Explanation:
To determine which is greater between [tex]9 \times 10^{-2 }[/tex] and [tex]3 \times 10^{-4}[/tex]we need to understand how to interpret numbers in scientific notation. The expression [tex]9 \times 10^{-2 }[/tex] means 9 times 1 following 2 zeroes to the left, resulting in 0.09. In the case of [tex]3\times 10^{-4}.[/tex] it means 3 times 1 following 4 zeroes to the left, producing 0.0003.
Comparing these values, [tex]9 \times 10^{-2 }[/tex] is clearly the larger number because 0.09 is greater than 0.0003. To find out how many times greater it is, we divide the larger number by the smaller one: 0.09 / 0.0003 equals 300. Therefore, [tex]9 \times 10^{-2 }[/tex]is 300 times greater than [tex]3\times 10^{-4}.[/tex]

What square roots of 10 lies between which two whole numbers?
The square root of 10 lies between two whole numbers, 3 and 4. This concept can be understood using number sense and geometry.
The square root of 10 falls between two whole numbers. To determine these two numbers, we need to consider the closest perfect square numbers to 10. These are 9 (the square root of 9 is 3) and 16 (the square root of 16 is 4). Hence, the square root of 10 must be somewhere between 3 and 4. Using a calculator, we find the approximate square root of 10 to be around 3.16. So, the square root of 10 lies between 3 and 4.
This kind of problem is related to number sense and geometry, especially when it comes to understanding square roots.

Answer:
x = ± [tex]\sqrt{\frac{ab+2}{3} }[/tex]
Step-by-step explanation:
Given
3x² - 2 = ab ( isolate the x² term by adding 2 to both sides )
3x² = ab + 2 ( divide both sides by 3 )
x² = [tex]\sqrt{\frac{ab+2}{3} }[/tex] ( take the square root of both sides )
x = ± [tex]\sqrt{\frac{ab+2}{3} }[/tex]
Answer:
x = √ [(ab + 2)/ 3]

Answer:x f(x) = 2.5x − 10.5 g(x) = 64(0.5x)
2 f(2) = 2.5(2) - 10.5 g(2) = 64(0.5*2)
f(2) = 5 - 10.5 g(2) = 64(1)
f(2) = -5.5 g(2) = 64
3 f(3) = 2.5(3) - 10.5 g(3) = 64(0.5*3)
f(3) = 7.5 - 10.5 g(3) = 64(1.5)
f(3) = -3 g(3) = 96
4 f(4) = 2.5(4) - 10.5 g(4) = 64(0.5*4)
f(4) = 10 - 10.5 g(4) = 64(2)
f(4) = -0.5 g(4) = 128
5 f(5) = 2.5(5) - 10.5 g(5) = 64(0.5*5)
f(5) = 12.5 - 10.5 g(5) = 64(2.5)
f(5) = 2 g(5) = 160
6 f(6) = 2.5(6) - 10.5 g(6) = 64(0.5*6)
f(6) = 15 - 10.5 g(6) = 64(3)
f(6) = 4.5 g(6) = 192
The hypotenuse of a right triangle is 13 inches. If the long leg is 7 inches longer than the short leg, find the lengths of the leg using the Pythagorean theorem
Answer:
The length of the short leg is 5 inches and the leg of the long leg is 12 inches
Step-by-step explanation:
Let
a -----> the long leg of a right triangle
b ----> the short leg of a right triangle
c ----> the hypotenuse of a right triangle
we know that
Applying the Pythagoras Theorem
[tex]c^{2} =a^{2}+b^{2}[/tex] -----> equation A
we have that
[tex]a=b+7[/tex] -----> equation B
[tex]c=13\ in[/tex] ----> equation C
Substitute equation B and equation C in equation A and solve for b
[tex]13^{2} =(b+7)^{2}+b^{2}[/tex]
[tex]169=b^2+14b+49+b^2[/tex]
[tex]2b^2+14b+49-169=0[/tex]
[tex]2b^2+14b-120=0[/tex]
Solve the quadratic equation by graphing
The solution is [tex]b=5\ in[/tex]
see the attached figure
Find the value of a
[tex]a=b+7[/tex] ----> [tex]a=5+7=12\ in[/tex]
therefore
The length of the short leg is 5 inches and the leg of the long leg is 12 inches
The lengths of the leg : 12 and 5
Further explanationQuadratic function is a function that has the term x²
The quadratic function forms a parabolic curve
The general formula is
[tex]\large {\boxed {\bold {f (x) = ax ^ 2 + bx + c}}}[/tex]
where a, b, and c are real numbers and a ≠ 0.
There are 3 ways to solve quadratic equations
a. factoring b. perfect squared c. quadratic formula
We use the factoring method
Quadratic equation x² + bx + c = 0 is equivalent to quadratic equation
[tex]{\displaystyle {x ^ 2 + (p + q) \times \: pq}}[/tex]
where p + q = b and px q = c
for a = 1, the result of factoring is (x + p) (x + q)
If at an angle there is an angle of 90 degrees, this triangle is said to be a right angle
There is a hypotenuse in this triangle which is the sum of the two sides
c² = a² + b²where c = hypotenuse
This formula is known as the Pythagorean theorem which states that:
the hypotenuse or the longest side in a right triangle equal to the sum of the squares of the other sides.
The hypotenuse of a right triangle is 13 inches
then c = 13
If the long leg is 7 inches longer than the short legthen a = b + 7
Then the phytagorean equation becomes:
(b + 7)² + b² = 13²
49+14b+b²+b²=169
49+14b+2b²=169
2b²+14b-120=0
b²+7b-60=0
factoring
(b-5)(b+12)=0
b=5 or b=-12
we use positive number ⇒5
So :
the long leg = b+7=5+7=12
the short leg = b = 5
