Step-by-step explanation:
An object is launched straight into the air. The projectile motion of the object can be modeled using h(t) = 96t – 16t2, where t is the time since launch and h(t) is the height in feet of the projectile after time t in seconds. When will the object be 144 feet in the air? When will the object hit the ground?
Answers
Answer:
first one is 3 seconds second one is 6 seconds
Step-by-step explanation:
The object will hit the ground in 3 seconds.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The given function is h(t)=96t-16t².
The object be 144 feet in the air.
144=96t-16t²
144=16(6t-t²)
t²-6t+9=0
By splitting middle term method, we get
t²-3t-3t+9=0
t(t-3)-3(t-3)=0
t-3=0
t=3
Therefore, the object will hit the ground in 3 seconds.

What term should be added to y2-14y to make it a perfect square
trinomial?
Answers
Answer:
49
Step-by-step explanation:
Given the monomial y²-14y, in order to make the binomial a perfect square, we need to add a constant to the function using completing the square method.
To get the constant, we will multiply the coefficient of y by 1/2 and then square the resulting value.
- The coefficient of y is -14.
multiplying the coefficient of y by 1/2 will give -14/2 = -7
- squaring -7 will result in (-7)²
= 49
The constant that will be added to the binomial to make it a perfect square trinomial is 49

Solve for z-
-0.25z = -1.25
z = ___
Answers
Answer:
5
Step-by-step explanation:
The value of z in the equation -0.25z = -1.25 is simplified to z = 5.
To solve for z in the equation -0.25z = -1.25, we need to isolate z by performing the necessary operations.
We can start by dividing both sides of the equation by -0.25 to cancel out the coefficient of z:
-0.25z / -0.25 = -1.25 / -0.25
This simplifies to:
z = 5
Therefore, the value of z in the equation -0.25z = -1.25 is z = 5.

The domain of a function is the set of x values for which it is defined. The correct option is D.
What is the domain and range of a function?The domain of a function is the set of x values for which it is defined, whereas the range is the set of y values for which it is defined.
To find the domain of the function it needed to be simplified. Therefore, the function can be rewritten as,
[tex]f(x) = \dfrac{3x}{4x^2-4}\\\\f(x) = \dfrac{3x}{4(x^2-1)}[/tex]
As it can be seen that for the fraction of the value of x is kept -1 or 1, then the denominator of the function will become zero, which is undefined.
Hence, the domain of the given function is all real numbers except x = –1 and x = 1.

Given the following exponential function, what is the initial amount y 60(1.71)^x?
Answers
Answer:
60
Step-by-step explanation:
The initial y value can be found by setting x to 0. Anything to the power of 0 is 1, so 1.71^x when x is 0 is just 1. 60*1=60, which is the initial y value. Hope this helps!
The initial amount 'y' of the exponential function [tex]y = 60(1.71)^x[/tex] is 60. This value represents the function's y-intercept, the amount present before any exponential growth occurs.
The student has provided an exponential function and wishes to know the initial amount, which can be expressed as 'y' in the function [tex]y = 60(1.71)^x[/tex]. The initial amount when x=0 is the coefficient of the exponential term. For this function, when x equals 0,[tex](1.71)^0[/tex] is 1, since any number raised to the power of 0 is 1. Therefore, the initial amount or the y-intercept of this function is 60.
This value represents the starting quantity before any growth (or decay if the base were less than 1) has occurred in the context of the function. It is important to note that the base of the exponential function (1.71 in this case) indicates the rate of growth per unit increase of the variable x

Marion/Elaine have $300.00
Marion/Elaine need $700.00
Subtract them from each other and that equals $400.00 dollars that they need.
Since it is a 5 week period this is over, you can divide 400 by 5, what do you get? $80.00

The product of 21 and a number u is at most 126
Answers
Answer:
21u is less than or equal too 126
Step-by-step explanation:
Final answer:
The inequality 21u ≤ 126 is solved by dividing both sides by 21, resulting in u ≤ 6.
Explanation:
The product of 21 and a number u is at most 126 can be expressed as an inequality: 21u ≤ 126. To solve for u, we divide both sides of the inequality by 21, the coefficient of u. Doing so, we find that u ≤ 6. Therefore, the number u can be any number less than or equal to 6 so that the product of 21 and u does not exceed 126.
