Answer:
Larry's statement is correct
Step-by-step explanation:
Larry says 5 × 900 is less than 5 × 9,000.
Doni says 5 × 900 is greater than 5 × 9,000.
5 × 900 = 4500
5 × 9000 = 45,000
45,000 is greater than 4500 because the place value of 45,000 is tens thousands and 4500 is Thousands.
Hence, Larry's statement is correct.(Larry says 5 × 900 is less than 5 × 9,000.)
X + y = 4
Is how you would write it in standard form.
3√(5c)×7√(15c²)
21√(75c³)
21√(25 c² 3c)
21√(5² c² 3c)
21× 5c√(3c)
105c√(3c)
Answer:
a. 2.56 sec
b. 65.96 feet.
Step-by-step explanation:
a) The equation of motion of a body under gravity gives the equation
......... (1) {Where u is the initial velocity of the body and t is the time to descend h height and g is the acceleration due to gravity.
Now, from the equation (1) we have
{Since g = 32 feet/sec² }
⇒ 
So, applying Sridhar Acharya formula
seconds {Neglecting the negative root as t can not be negative.} (Answer)
b) Again we have the formula that
{Where v is the final velocity before hitting the ground.}
⇒ 
⇒ v = 65.96 feet / sec. (Answer)
Answer: y = 3x/2 + 8
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
c represents the y intercept
m represents the slope of the line.
The equation of the given line is
y = - 2x/3 + 5
Comparing with the slope intercept form, slope = - 2/3
If two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the other line.
Therefore, the slope of the line passing through (2, 11) is 3/2
To determine the y intercept, we would substitute m = 3/2, x = 2 and y = 11 into y = mx + c. It becomes
11 = 3/2 × 2 + c
11 = 3 + c
c = 11 - 3 = 8
The equation becomes
y = 3x/2 + 8
