suppose you lean out a window of a tall building and use a sling to launch a stone straight up. the stone starts with a velocity of 69 feet per second. it leaves the sling 365 feet above the ground.
Answers
Answer:
y= 69x + 356
Step-by-step explanation:
y= 69x + 356
It goes 69 feet per second hence the 69x and it starts 356 feet in the air
The height of the stone above the ground at any time t can be described by the quadratic function h(t) = -16t^2 + 69t + 365.
How to write a function?Assuming that the acceleration due to gravity is -32 feet per second squared (neglecting air resistance), we can use the following kinematic equation to describe the height of the stone as a function of time:
h(t) = -16t²+ vt + h₀
where:
h(t) is the height of the stone above the ground at time t
v is the initial velocity of the stone (69 feet per second, in this case)
h₀ is the initial height of the stone (365 feet above the ground, in this case)
Substituting the values of v and h0, we get:
h(t) = -16t² + 69t + 365
Therefore, the height of the stone above the ground at any time t can be described by the quadratic function h(t) = -16t² + 69t + 365.

Answers
Answer:
375 lines
Step-by-step explanation:
Total ounces of rain water in the barrel = 3,750 ounces
Measurement lines in the barrel = 10 ounces per line
how many lines did the water reach?
Number of lines the water reach = Total water in the barrel / measurements per line
= 3,750/10
= 375 lines
The water in the barrel reach 375 lines

A square box lid has an area of 50 square inches. Which is the best estimate of the length of one side?
Answers
Answer: 7.1 inches
Step-by-step explanation:
The area of a square is simply the square of one of its length. Therefore since we are informed that the area of the square box is given as 50 inches².
Then the best estimate of the length of one side will be the square root of 50 which will be:
= ✓50
= 7.1 inches approximately

Answers
Answer:
the answer is D.
Step-by-step explanation:
well, the y-intercept for f(x) is at
as you can see from the slope-intercept form is at 4, and it has an slope of 2/3.
for g(x), well an y-intercept is when x = 0, what is it from that table? well, is at 0,3, so when x = 0, y = 3, so no dice on that one.
c)
whenever an x-intercept occurs, y = 0, for f(x) that's at
what about the x-intercept for g(x)? well, let's check, when is y = 0? aha! at -9, 0, so when y = 0, x = -9, so no dice on that one either.
d)
well, what is the slope of g(x) anyway? well, let's pick two points off the table to get it hmmm the first two let's use,
and from a), using the slope-intercept form, we know f(x) has a slope of 2/3.
well, 2/3 is larger than 1/3, so no dice.
b)
well, you already know.
La ecuación de la recta que lasa a través de los puntos P1 (2,5) y P2 (4,11) es: a) 3x+y+1=0 b)3x-y-1=0 c) 3x-y+1=0
Answers
Respuesta:
3x-y-1 = 0
Explicación paso a paso:
La forma estándar de ecuación de una línea se expresa como y = mx + b
M es la pendiente
b es la intersección con el eje y
Dada la coordenada P1 (2,5) y P2 (4,11)
Pendiente m = y2-y1 / x2-x1
m = 11-5 / 4-2
m = 6/2
m = 3
Sustituya m = 3 y (2,5) en y = mx + b
5 = 3 (2) + b
5 = 6 + b
b = 5-6
b = -1
Obtén la ecuación
y = 3x-1
Igualar a cero
y - 3x +1 = 0
Multiplicar por -1
3x-y-1 = 0
Esto da la ecuación requerida

Answers
Answer: <1 = 105° and <2 = 75°
Step-by-step explanation:
The information we have is the 75 degree angle already provided. Using our knowledge on transverses we know a 180 degree angle is a straight line (we happen to have two of these (c and d)). Using the corresponding angle theorem we know angle 2 is equivalent to 75 degrees. Supplementary angles refer to angles that add up to 180 degrees. Angle 1 and 2 are supplementary so from there we solve.
180 - 75 = 105
<1 = 105 degrees

A rectangle has a perimeter of 30 yards. If one side is 5 yards long, how long is the other side?
A. 15 yards
B. 25 yards
C. 10 yards
D. 30 yards
Answers
Answer:
C. 10
Step-by-step explanation:
5+5=10
10+10=20
10+20=30
Answer:
The other is 10 yards long
Step-by-step explanation:
For a given rectangle
Perimeter (P) = 30 yards
and one of rectangle is 5 yards
Now,
Perimeter of rectangle
P = 2l + 2b
30 = 2(5) + 2b
30 = 10 + 2b
30 - 10 = 2b
20 = 2b
b = 20 ÷ 2
b = 10 yards
Thus, The other is 10 yards long

Answer:
x = 36 degrees
y = 48 degrees
Step-by-step explanation:
The two given triangles are congruent
Hence, we can say that the interior angles are equal
We shall use the angle markings on each of the triangles
Using the markings, we can see that y is 48 degrees
Now, let us find the last angle measure of the first triangle
Mathematically, the sum of angles in a triangle is 180
Thus;
108 + 48 + A = 180
A = 180 - 48 - 108
A = 180 - 156 = 24
Now, the measure 2x-y is equal to this;
Hence;
2x -y = 24
2x = 24 + y
we have that y = 48
2x = 24 + 48
2x = 72
x = 72/2
x = 36 degrees
