A catapult launches a boulder with an upward velocity of 120 ft/s. The height of the boulder, h,
in feet after t seconds is given by the function h=-16t^2 + 120t + 10. How long does it take to
reach maximum height? What is the boulder's maximum height? Round to the nearest
hundredth, if necessary.
a. Reaches a maximum height of 235.00 feet in 3.75 seconds.
b. Reaches a maximum height of 10.00 feet in 7.50 seconds.
c. Reaches a maximum height of 7.58 feet in 3.75 seconds.
d. Reaches a maximum height of 15.16 feet in 7.5 seconds.
Answer:
The boulder's maximum height is:
a. Reaches a maximum height of 235.00 feet in 3.75 seconds.
Step-by-step explanation:
The easiest way to solve the unknown is to replace the time in the given equation, with the values given in the answer, look for the highest value and check if the height value decreases as the time increases or decreases.
First the equation provided is taken:
h = -16t ^ 2 + 120t + 10The time values in the options are 3.75 seconds and 7.5 seconds, therefore we proceed to replace this formula with those values:
h (3.75) = - 16 (3.75) ^ 2 + 120 (3.75) + 10 = 235 h (7.5) = - 16 (7.5) ^ 2 + 120 (7.5) + 10 = 10Since a higher height value is obtained with 3.75 seconds (235 feet), this time will be taken as appropriate, however, it is best to check that by using more time and less time, the height decreases from that value, so we will take two very close times: 3.74 seconds and 3.76 seconds:
h (3.74) = - 16 (3.74) ^ 2 + 120 (3.74) + 10 = 234.9984 h (3.76) = - 16 (3.76) ^ 2 + 120 (3.76) + 10 = 220.5884As you can see, if slightly higher or lower time values are taken, the height of the rock still decreases from 235 feet, so we can be sure that the time in which it reaches its maximum height is 3.75 seconds.

Which choices are in the solution set of the equation below? Check all that
apply.
25x = 40
The solution set for the equation 25x = 40 is {1.6}, obtained by dividing both sides by 25 and verifying the solution by substitution.
Explanation:To find the solution set of the equation 25x = 40, we need to isolate the variable x by performing algebraic operations. The goal is to get x by itself on one side of the equation. This involves dividing both sides of the equation by the coefficient of x, which in this case is 25. Following this step, we arrive at the equation x = 40 / 25.
By simplifying 40 / 25, we find that x = 1.6. Therefore, the solution set for the equation 25x = 40 is {1.6}. It’s important to check the solution by substituting it back into the original equation to ensure that it satisfies the equation:
25(1.6) = 40
40 = 40
This indeed confirms that x = 1.6 is the correct solution. In mathematics, solving linear equations such as this one is a fundamental skill that involves understanding algebraic manipulation and the properties of equality.
The solution set for the equation 25x = 40 is x = 8/5. In other words, the only value for x that satisfies the equation is 8/5.
The solution set for the equation 25x = 40, we can isolate the variable x by dividing both sides of the equation by 25:
x = 40/25
Simplifying the right side gives:
x = 8/5
So, the solution set for this equation is {8/5}. In other words, the only value for x that satisfies the equation is 8/5. To understand this, you can substitute this value back into the original equation:
25 * (8/5) = 40
Simplifying the left side:
200/5 = 40
Indeed, the equation holds true.
In summary, the only choice in the solution set for the equation 25x = 40 is x = 8/5. This means that when you substitute 8/5 for x in the equation, both sides will be equal.
in an exponential function, (x) = a(b)^x, it is known that f(5)=15 and f(8)=170. which of the following is closest to the value of b?
(1)1.87
(2)2.25
(3)3.19
(4)3.72
Answer:
2.25
Step-by-step explanation:
5=15 and d8=170=which of the following is closest to the value of fb
The value of b is closest to (2) 2.25
An exponential function is represented as:
[tex]f(x) = a(b)^x[/tex]
[tex]f(5) = 15[/tex] means that:
[tex]ab^5 = 15[/tex] ---- equation (1)
[tex]f(8) = 170[/tex] means that:
[tex]ab^8 = 170[/tex] ---- equation (2)
Divide equation (2) by equation (1)
[tex]\frac{ab^8}{ab^5}= \frac{170}{15}[/tex]
Divide common factors
[tex]b^3= 11.33[/tex]
Take the cube root of both sides
[tex]b= \sqrt[3]{11.33}[/tex]
Evaluate the expression
[tex]b= 2.246[/tex]
2.246 can be approximated to 2.25
Hence, the value of b is closest to (2) 2.25

There is a relay race with 4 runners. The total distance run in the relay race is m
miles. Write an expression to show how far each person runs in the relay race.
In a relay race with 4 runners covering a total distance of m miles, each runner will cover an equal share of the distance, specifically m ÷ 4 miles.
Explanation:If there is a relay race with 4 runners and the total distance run is m miles, we want to find the distance each person runs. Since the total distance is divided equally among the 4 runners, we can express the distance each runner will run as:
The distance each runner runs = Total distance ÷ Number of runners
The distance each runner runs = m ÷ 4
This expression shows that each runner will run a quarter of the total distance m.

solve for the unknown variable 2/5(3x-4)=-4
Answer:
x = -2
Step-by-step explanation:
Solve for x:
(2 (3 x - 4))/5 = -4
Multiply both sides of (2 (3 x - 4))/5 = -4 by 5/2:
(5×2 (3 x - 4))/(2×5) = -4×5/2
5/2×2/5 = (5×2)/(2×5):
(5×2)/(2×5) (3 x - 4) = -4×5/2
5/2 (-4) = (5 (-4))/2:
(5×2 (3 x - 4))/(2×5) = (-4×5)/2
(5×2 (3 x - 4))/(2×5) = (2×5)/(2×5)×(3 x - 4) = 3 x - 4:
3 x - 4 = (-4×5)/2
(-4)/2 = (2 (-2))/2 = -2:
3 x - 4 = 5×-2
5 (-2) = -10:
3 x - 4 = -10
Add 4 to both sides:
3 x + (4 - 4) = 4 - 10
4 - 4 = 0:
3 x = 4 - 10
4 - 10 = -6:
3 x = -6
Divide both sides of 3 x = -6 by 3:
(3 x)/3 = (-6)/3
3/3 = 1:
x = (-6)/3
The gcd of -6 and 3 is 3, so (-6)/3 = (3 (-2))/(3×1) = 3/3×-2 = -2:

which event has exactly 12 possible outcomes
Final answer:
An event with exactly 12 possible outcomes may refer to rolling a single 12-sided die, rolling two six-sided dice with one specific number on one die and any number on the other, or flipping a coin and rolling a six-sided die.
Explanation:
The event that has exactly 12 possible outcomes could be the rolling of a 12-sided die once, which would result in one of the twelve numbers coming up. Another example is rolling two six-sided dice and considering the situation where one specific number must come up on one die, while any of the six numbers could come up on the other die, thus also resulting in 12 possible outcomes (6 possible outcomes for the second die, times 1 fixed outcome for the first die), assuming the outcome of interest is only about the second die. Yet another example could be flipping a coin and rolling a six-sided die, where the coin has two possible outcomes (heads or tails) and the die has six possible outcomes, giving us a total of 12 outcomes (2 x 6 = 12).

Multiply
[(4a + 4)(a²)] / [(2a)(a + 1)]
(4a³ + 4a²) / (2a² + 2a)
2a(2a² + 2a) / 2a(a + 1)
(2a² + 2a) / (a + 1)
2a(a + 1) / (a + 1)
= 2a

hich is the graph of the linear function that is represented by the equation y= 1/2x-2 ?
Answer:
this is the best way i could explain
Step-by-step explanation:
remember that the equation of a line is y = mx +b, where m is the slope and b is the y-intercept.
Start with your first point on the y-axis at -2. Your slope is 1/2 (rise/run), so go up 1 and over 2 for your next point. Keep going with this and you'll find your points.
Another way to find your y-values is to plug in the x's you have. y = 1/2(2) - 2 = 1 - 2 = -1, so your first point is (2,-1). This should show up on your graph, as well.
What do you get when you plug in the 0? Your answer should be your first point on your graph, since along the y-axis, x = 0.
The graph of the equation given is attached to the solution.
Given that, an equation y = 1/2 x - 2, we need to graph it,
So, for the same, we will first find the coordinates points,
Therefore,
y = 1/2 x - 2
Put y = 0,
1/2 x - 2 = 0
x = 4
The point = (4, 0)
Put x = 0,
y = -2
The point = (-2, 0)
Put the coordinates in the graph and join the points, we will have a straight line, this straight is the graph of the linear equation given,
