The height, h, in feet of a golf ball above the ground after being hit into the air is given by the equation, h = -16t 2 + 64t, where t is the number of seconds elapsed since the ball was hit. How many seconds does it take for the golf ball to hit the ground?
It will take ___seconds for the ball to hit the ground.
Answers
Answer:
4 seconds
Step-by-step explanation:
When the ball hits the ground the height is 0
-16t² + 64t = 0
Divide both sides by -16
t² - 4t = 0
Factor out t
t(t - 4) = 0
From the zero product rule
t = 0 and t - 4 = 0
t = {0, 4}
The ball hits the gound after 4 seconds

Step-by-step explanation:
A rectangular football field is 64 meters wide and 100 meters long. A player runs from one corner of the field in a diagonal line to the opposite corner. How far did the player run? Round to the nearest whole meter. *115 meters
118 meters
119 meters
120 meters
Answers
Answer:
119meters
Step-by-step explanation:
We should use the Pythagorean Theorem to solve this problem.
a^2+ b^2=c^2
64^2+100^2=c^2
4096+10000=14096
c^2=14096
c=\sqrt{14096}
14096
And the root of 14096 is 118.726577.
So the Answer is About 119 meters, or 118.726577
Answer:
Solution given:
length[l]/base[b]=100m
wide [w]/perpendicular [p]=64m
distance of diagonal =hypotenuse [h]=?
By using Pythagoras law
h²=p²+b²
h²=64²+100²
h=√14096
h=118.72
=119m approx
So
the player run 119m.

Need help asap, it's asking me to find m angle J and that K = 25.

j would be 130 cuz sides that are congruent have congruent angles so you add those two angles up and subtract from 180
Answer:
Step-by-step explanation:
x = 130
Base angles of isosceles triangles are congruent so angle L is also 25
There is 180 degrees in a triangle so you would do 25 + 25 + x = 180

Answer in complete sentences.

Answer:
without doing the math, we can affirm that the percent in decrease in the price of the gloves is not the same as the percent increase of the goggles. decreasing $2 from $10 will have a lower decrease than an increase of $2 from $8 since $2 represents a higher portion of $8 compared to $10

Graph the line . djdjej
Answers
Answer:
Step-by-step explanation:
The slope is 2 and the point (0,8) is on the graph. This means we have to plug this equation to y-y1=m(x-x1) where m is the slope. We know the slope and the we have the points (0,8) so we can completely fill in this equation. y-8=2(x-0) is equal to y-8=2x. You want to isolate y so you have to add 8 to both sides. y=2x+8. The graph y=2x+8 will look like this.

Un hotel tiene 120 habitaciones, entre dobles i individuales. Si la cuantidad de camas son de 195, cuantas habitaciones dobles hay? Y individuales?
Answers
Answer:
45 individuales y 75 dobles.
Step-by-step explanation:
Para saber esto, debemos plantearlo por medio de un sistema de ecuaciones. En este caso las incógnitas serían el tipo de habitación, es decir, una será la habitación doble, y la otra la individual.
X: habitaciones individuales
Y: habitaciones dobles
Sabiendo eso, sabemos que sumando ambos tipos de habitaciones, dan el total de 120, por tanto, la primera ecuación será:
x + y = 120 (1)
Para la segunda ecuación, sabemos que hay 195 camas en total, que deben distribuirse en los dos tipos de habitaciones, en una habitación doble van 2 camas, mientras que en una individual va 1, por tanto:
x + 2y = 195 (2)
Ahora que tenemos las dos ecuaciones, solo resta resolverlo por alguno de los métodos conocidos de sistema de ecuaciones. En este caso, como las ecuaciones son sencillas podemos usar el método de reducción.
En la siguiente foto, está el procedimiento.
