Answer:
y
Step-by-step explanation:
Like radicals are radicals that have the same radical (the number into the square root) and the same radicand (the number above the root)
Here, only the last expression can be chosen.
The area of a square is (side)².
If the area is 128m², then the side is (√128) meters. (That's 8√2.)
The diagonal is the hypotenuse of the right triangle you get
if you slice the square in half along the diagonal. Its length is
given in the words of Old Pythagoras:
c² = a² + b²
'a' and 'b' are sides of the square, so
c² = (√128)² + (√128)²
= 2 (√128)²
c = √ (2 x 128) = √256 = 16 meters .
Given:
The table of values.
Hours (h) Dollars (d)
1 42
2 84
3 126
4 168
5 ?
To find:
The correct statements about the table.
Solution:
From the given table it is clear that,
This pattern can be defined as
Multiply h by 42 to get d. So, option A is correct.
Using this pattern, we get
The missing value in the last row is 210. So, option D is correct.
From the given table it is clear that the rate of change is $42 per hour because dollar is increasing by 42 in every hour.
A real-world situation that is represented in the table is “Richard is a video game designer and earns $42 per hour.”
Therefore, the option E is correct.
Answer:
Tenía que hacerlo en menos de 2 minutos a más de 240 km/h
Step-by-step explanation:
La velocidad normal dada para completar el circuito de 6.000 metros = 240 km/h
El tiempo normal que se tarda en completar el circuito de 6000 metros = 2 minutos
Dado que Hamilton estableció el récord de vuelta, el tiempo que tuvo que hacer para recorrer el récord de vuelta es de 6000 metros en menos de 2 minutos
La velocidad media con la que lo hizo es de más de 240 km/h.
<span>a. n/4 ≤ -1
Multiply both sides by 4 => n ≤ - 4, which is all the real numbers less or equal than - 4.
That in the real number line is all the numbers to the left of - 4 (including -4)
The matching graph is the B.
b. -10n ≥ -100
Divide both sides by - 10 => n ≤ 10
That is all the real numbers less or equal than 10.
In the real number line it is all the numbers to the left of 10, including 10.
So, the matching graph is the A.
c. 5x ≥ 20
Divide both sides by 5 => x ≥ 4
That is all the real numbers greater or equal to 4.
In the real number line it is all the numbers to the right of 4, including 4.
The matching graph is C.</span>
