Answer:
The first golf ball went higher.
Step-by-step explanation:
The equation representing the height (in feet) of a golf ball t seconds after it is hit is:
And the graph represents the height of a second golf ball t seconds after it is hit.
From the graph it can be seen that the second ball reaches its maximum height, i.e. 100 feet, after 2.5 seconds.
Compute the height of the first ball after 2.5 seconds as follows:
After 2.5 seconds the first ball reaches a height of 140 feet.
This height may or may not be the maximum height.
But for the same time, the first ball goes higher that the second ball.
Thus, the first golf ball went higher.
Answer:
Divide a percent by 100 and remove the percent sign to convert from a percent to a decimal. The shortcut way to convert from a percentage to a decimal is by removing the percent sign and moving the decimal point 2 places to the left.
Step-by-step explanation:
5.25% = .0525
Kono Dio Da
p=price of television before reduction
7/10 = 30% reduction as 70/100 is 7/10.
-------------------------------------------------------
7/10*p=$161
7p=$1,610
p=($1,610)/7
p=$230
Answer:
A
Step-by-step explanation:
on the left of the equation, (6^4)^-5 = 6^-20
the right side you add the exponents so it would be (-7-3) =-10
so it would be 6^-10, which is greater than 6^-20

Answer:
yes
Step-by-step explanation:
The tower is about 50.1 meters tall. The guidebook is correct.
__
The distance from the base of the tower to the angle vertex is ...
d1 = h/tan(46°)
d2 = d1 +50 = h/tan(27°)
Then the height of the tower is ...
h/tan(46°) +50 = h/tan(27°)
50 = h(cot(27°) - cot(46°))
h = 50/(cot(27°) -cot(46°)) ≈ 50/(1.96261 -0.96569) ≈ 50/0.99692
h ≈ 50.1544 . . . meters
The tower is more than 50 meters high.
