Step-by-step explanation:
To add these two numbers, we simply add their corresponding place values:
(5.87 x 10^7) + (2.7 x 10^6)
To align the numbers correctly, we need to adjust the second number:
(5.87 x 10^7) + (0.27 x 10^7)
Now, we can add the numbers:
(5.87 + 0.27) x 10^7
= 6.14 x 10^7
Therefore, (5.87 x 10^7) + (2.7 x 10^6) equals 6.14 x 10^7.At noon, Trevor and Kim start running from the same point. Trevor runs east at a speed of 8 km/h and Kim runs west at a speed of 6 km/h. At what time will they be 21 km apart?
Trevor and Kim will be situated 21 kilometers apart from each other at 1:30 PM. They will be separated by a distance of 21 km when the clock strikes 1:30 in the afternoon.
To determine at what time Trevor and Kim will be 21 km apart, we can set up a distance-time equation based on their relative speeds and distances.
Let's assume that t represents the time elapsed in hours since noon. At time t, Trevor would have traveled a distance of 8t km, while Kim would have traveled a distance of 6t km in the opposite direction.
Since they are running in opposite directions, the total distance between them is the sum of the distances they have traveled:
Total distance = 8t + 6t
We want to find the time when this total distance equals 21 km:
8t + 6t = 21
Combining like terms, we have:
14t = 21
To solve for t, we divide both sides of the equation by 14:
t = 21 / 14
Simplifying, we find:
t = 3 / 2
So, they will be 21 km apart after 3/2 hours, which is equivalent to 1 hour and 30 minutes.
Therefore, Trevor and Kim will be 21 km apart at 1:30 PM.

How do I solve it

Answer: (7,10)
Step-by-step explanation:
The graph of the function f ( x ) is shown
The true statements for the given function f(x) are:
The value of g(1) is 3 and the y- intercept of g(x) is at the point (0, 1) .
How to calculate the values of the function?The function g(x) = f( x - 3 )
g (1) = f (1 -3 )
= f (-2 )
= 3
g (-1) = f (-1 -3)
= f (-4)
= - 1
Substituting , x = 0 to find the y intercept of g(x)
g ( 0 ) = f ( 0 - 3)
=f (-3)
=1
The y intercept of g(x) is at the point (0, 1)
Thus, options 1 and 4 are the true statements for the given function.

13) A hexagon has 6 equal sides! Ms. Sears asked the students to find the perimeter if all sides are equal to 2x + y. One student found the solution to be 18xy and another thinks it is 9xy. Is either solution correct? Show your work to justify your answer.
Answer:
None of the answers are right
Step-by-step explanation:
Since a hexagon has 6 sides, and perimeter is the length of all the sides summed up, we can multiply 6 by 2x+y to find the perimeter.
6(2x+y)
Distribute the 6 to each term in the parentheses:
6(2x)+6(y)

In 2010, the population of a city was 167,000. From 2010 to 2015, the population grew by 8%. From 2015 to 2020, it fell by 3%. How much did the population decrease from 2015 to 2020, to the nearest 100 people?
The population decreased by 5,400 people from 2015 to 2020.
By how much did the population decrease?Also known as population decline, means the reduction in a human population size
Population in 2015 = Population in 2010 + Growth from 2010 to 2015
Population in 2015 = 167,000 + (8% of 167,000)
Population in 2015 = 167,000 + 13,360
Population in 2015 = 180,360
Population in 2020 = Population in 2015 - Decrease from 2015 to 2020
Population in 2020 = 180,360 - (3% of 180,360)
Population in 2020 = 180,360 - 5,411.8
Population in 2020 = 174,948.2
The population decrease from 2015 to 2020 is:
= Population in 2015 - Population in 2020
= 180,360 - 174,948.2
= 5,411.8

2. Determine the points of intersection of each pair of functions. a) y = 4x^– 15x + 20 and y = 5x – 4 = - - b) y = - 2x^ + 9x +9 and y = - 3x – 5
To determine the points of intersection we first equate the expressions, then we solve for x. Once we have the values of x for which the functions are equal we plu them on one of the function to find its corresponding value of y.
a)
Let's equate the functions and solve for x:
\(\begin{gathered} 4x^2-15x+20=5x-4 \\ 4x^2-15x-5x+20+4=0 \\ 4x^2-20x+24=0 \\ 4(x^2-5x+6)=0 \\ x^2-5x+6=0 \\ (x-3)(x-2)=0 \\ \text{ then} \\ x=3 \\ or \\ x=2 \end{gathered}\)Now we find the corresponding values of y for each value of x; to do this we use the second equation.
When x=3:
\(\begin{gathered} y=5(3)-4 \\ y=15-4 \\ y=11 \end{gathered}\)Hence the functions intersect at (3,11)
When x=2:
\(\begin{gathered} y=5(2)-4 \\ y=10-4 \\ y=6 \end{gathered}\)Hence the functions intersect at (2,6)
Therefore the function intersect at the points (3,11) and (2,6).
b)
Let's equate the functions and solve for x:
\(\begin{gathered} -2x^2+9x+9=-3x-5 \\ 2x^2-9x-9-3x-5=0 \\ 2x^2-12x-14=0 \\ 2(x^2-6x-7)=0 \\ x^2-6x-7=0 \\ (x-7)(x+1)=0 \\ \text{ then} \\ x=7 \\ or \\ x=-1 \end{gathered}\)Now we find the corresponding values of y for each value of x; to do this we use the second equation.
When x=7:
\(\begin{gathered} y=-3(7)-5 \\ y=-21-5 \\ y=-26 \end{gathered}\)Hence the functions intersect at (7,-26)
When x=-1:
\(\begin{gathered} y=-3(-1)-5 \\ y=3-5 \\ y=-2 \end{gathered}\)Hence the functions intersect at (-1,-2)
Therefore the function intersect at the points (7,-26) and (-1,-2).
estimate the probability of winning $80 within 1000 sequential bets. explain your reasoning thoroughly.
The probability of winning $80 within 1000 sequential bets utilizing the Martingale strategy is close to 0%.
The probability of winning $80 using the Martingale strategy is close to 0% because the probability of winning at each bet is 0.47. This means that the expected value of our winnings after 1000 sequential bets is close to 0.
If we lose more than 4 times in a row (which is very likely if we have 1000 sequential bets), we have to double our bet each time and therefore we would need more money than what we initially have in order to keep betting. This means that the expected value of our winnings converges to 0 as the number of sequential bets increases.
Furthermore, the standard deviation of our winnings also converges to 0 as the number of sequential bets increases because the expected value of our winnings is 0. This means that the probability of winning any amount of money is close to 0.

What are the zeros of the function h (x) = x² + 3x - 8?
A
x = -8 and x = -2
OB
x= -8 and x = 2
cx = -2 and x = 8
OD x = 2 and x = 8
The following are the zeros for the function h (x) = x2 + 3x - 8: - x= -4 and x=2.
Describe functions.Given a collection of inputs X (domain) and a set of potential outputs Y (codomain), a function is more technically defined as a set of ordered pairings (x,y) where xX and yY with the caveat that there can only be one ordered pair with the same value of x. The function notation f:XY can be used to express that f is a function from X to Y.
The function's zero is a value of x that makes it equal to zero. In other words, the equation f(x) = 0 leads to a zero.
By putting h(x) equal to zero and figuring out x, we may determine the zeroes for the function h(x) = x2 + 3x - 8.
h(x) = x² + 3x - 8 = 0
We may factor the left side of the equation to find x:
x² + 3x - 8 = (x-2)(x+4) = 0
We set each factor to zero and solve for x to discover the zeroes:
x-2 = 0 or x+4 = 0
x = 2 or x = -4
Consequently, the function's zeros are x = 2 and x = -4.
So, A is the right response. x = -4 and x = 2

when solving an oblique triangle given three sides, use the ---select--- form of the law of cosines to solve for an angle.
When solving an oblique triangle given three sides, use the inverse cosine form of the Law of cosines to solve for an angle.
When solving an "oblique-triangle" given three sides, we would use the inverse cosine, form of the Law of Cosines to solve for an angle.
The "Inverse-Cosine" function allows us to find the measure of an angle when given the ratio of the lengths of the triangle's sides.
The "Law-of-Cosines" relates the lengths of the sides of a triangle to the cosine of one of its angles.
The "Law-of-Cosines" states that for any triangle with sides of lengths a, b, and c, and opposite angles A, B, and C, respectively:
⇒ c² = a² + b² - 2ab × cos(C),
To solve for an angle, we would rearrange the equation to find the cosine of the angle,
⇒ Cos(C) = (a² + b² - c²)/(2ab),
Then, we will take the inverse cosine of both sides of the equation to find the value of the angle,
⇒ C = cos⁻¹((a² + b² - c²)/(2ab)),
This helps us to find the measure of angle C, depending on the units used in the original triangle sides.

To factorize
\( = \frac{4x + 16}{2} \)
Taking "4" as common from 4x+16
\( = \frac{4(x + 4)}{2} \)
Cancelling 2 with 4
\( = 2(x + 4)\)
(since 4÷2=2)
Answer:
\(2(x + 4)\)
Step-by-step explanation:
According to this fraction:
Numerator = \(4x + 16\)
Denominator = \(2\)
Step I:
Focus on the two terms in the numerator and observe that their Highest Common Factor (HCF) is 4. This can be extracted out while factorising:
\(4x + 16\) = \(4 (x + 4)\)
∴ \(\frac{4x + 16}{2}\) = \(\frac{4(x + 4)}{2}\)
Step II:
The 4 (which is outside the parenthesis because it is extracted as the HCF) can be reduced by the 2 because of the division sign:
\(\frac{4(x + 4)}{2}\) = \(\frac{4}{2}\) × \((x + 4)\)
= \(2\) × \((x + 4)\)
= \(2(x + 4)\)
