A classic physics problem states that if a projectile is shot vertically up into the air with an initial velocity of 151 feet per second from an initial height of 95 feet off the ground, then the height of the projectile, h, in feet, t seconds after it's shot is given by the equation:
h = - 16t² + 151t +95
Answers
Answer:
Step-by-step explanation:
144 = -16t² + 151t + 95
0 = -16t² + 151t - 49
quadratic formula
t = (-151 ±√(151² - 4(-16)(-49))) / (2(-16))
t = (-151 ± 140.23195) / -32
t = 0.34 s
t = 9.10 s

pls change this to decimal number 1011111 base 2
Answers
===========================================================
Explanation:
Check out the table below. Each 1 and 0 corresponds to a power of 2. A 1 indicates that we'll add on that power of 2 while a 0 means we ignore it. We will add up the items in the second row that correspond to a "1" in the first row.
We get:
2^6+2^4+2^3+2^2+2^1+2^0 = 64+16+8+4+2+1 = 95
Effectively, we add nearly everything in the second row except for the 2^5 term.
Therefore, the number 1011111 base 2 is equivalent to 95 base 10.

Answers
Answer:
0.004567 kilograms
Step-by-step explanation:
4.567 grams=4.567÷1000=0.004567
becouse 1 kilogram = 1000grams
The conversion of 4,567 grams into kilograms will give the result of 0.004567 kilograms.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
We need to Convert grams to kilograms by completing the number sentences.
Since, 1 kilogram = 1000 grams
4.567 grams = 4.567 ÷ 1000
4.567 grams = 0.004567
Therefore, the conversion of 4,567 grams into kilograms will give the result of 0.004567 kilograms.

One-fifth of the length of a foot-race is 3 miles. Find the length of the race
Answers
Answer:
let's call the entire length of the foot race we are looking for: d
for distance.
We can then rewrite this problem as:
One-third of d
is 5 miles. What is d .
When dealing with fractions in this way the word "of" means to multiply. So we can write this problem in algebraic form as:
1 3 × d = 5
We can multiply each side of the equation by
3 to solve for d
while keeping the equation balanced:
3 × 1 3 × d = 3 × 5
3 3 × d = 15 1 × d = 15 d = 15
The length of the race is 15 miles.

The graph below is the function f(x)
Find lim x -> -1- f(x)=
Answers
As x approaches -1 from the left, the graph of f(x) leads you to the point (-1, 3), so the limit from the left is 3.
As x approaches -1 from the right, the graph leads to the point (-1, -3), so the limit from the right is -3.
The one-sided limits do not match, so the two-sided limit does not exist.
But f(x) is still defined at x = -1; this is indicated by the point (-1, -1). So f (-1) = -1.
We have found all the given limits for all the function.
What is limit of a function?
The limit of a function is a key notion in calculus and analysis that describes how the function behaves near a certain input.

{ x - 3y= -3 & x + y= 5 We are to use the graph to solve the given system of equations, then enter your solution below. I get how to draw the second equation but not the first. found slope of 1/3 & b=1. i dont understand how to graph this. I have tried different ways but keep getting it wrong.
Answers
Answer:
Solution: (3, 2)
Step-by-step explanation:
It's easier to graph when the equation of the lines are in their slope-intercept form, y = mx + b.
x - 3y = -3
-3y = -x - 3
Divide both sides by -3:
[tex]\frac{-3y}{-3} = \frac{-x - 3}{-3}[/tex]
y = 1/3x + 1
where slope = 1/3
y-intercept = 1
x + y = 5
Subtract x from both sides to isolate y:
x - x + y = - x + 5
y = -x + 5
where slope = -1
y-intercept, 5
I started by graphing the y-intercepts of each line. Then, I used the slope of each linear equation (rise over run) to plot the next points on the graph. In the attached screenshot of the graph, x - 3y = -3 is the blue line, while x + y = 5 is the green line. Their intersection occurs at point, (3, 2).
Therefore, the solution is (3, 2).
