Answer:
a. 8m
b. 7cm
Step-by-step explanation:
a. Area of a square is s², where s is the side length.
To find s:
s² = 64
s = √64
s = ±8
length cannot be negative, hence it is positive 8
b. Perimeter of a square is 4s = P, where P is the perimeter and s is the side length.
4s = 28
s = 7
Solve for p:
2p + 3 = 25
Answer:
p = 11

Answer:
20 feet
Step-by-step explanation:
We can use scale factors to represent the lengths. Since the flagpole's base is 4 times the tree's height, we can also say that the flagpole's height is 4 times the tree's height. Since the tree's height is 5 feet, the flagpole's height is 4 x 5, which is 20.
A ball is thrown vertically upward with an initial velocity of 64 feet per second. The distance s (in feet) of the ball from the ground after t seconds is s=64t-16t^2 (a) At what time t will the ball strike the ground? (b) For what time t is the ball more than 48 feet above the ground?
Given:
The distance s (in feet) of the ball from the ground after t seconds is
[tex]s=64t-16t^2[/tex]
To find:
(a) At what time t will the ball strike the ground?
(b) For what time t is the ball more than 48 feet above the ground?
Solution:
(a)
We have,
[tex]s=64t-16t^2[/tex]
Substitute s=0, to find the time t when the ball strike the ground.
[tex]0=64t-16t^2[/tex]
[tex]0=16t(4-t)[/tex]
Using zero product property, we get
[tex]16t=0\Rightarrow t=0[/tex]
[tex]4-t=0\Rightarrow t=4[/tex]
Therefore, the ball strike the ground in initial condition (t = 0) and after 4 seconds (t = 4).
(b)
Now, s > 48, to find the time t when the ball will be more than 48 feet above the ground.
[tex]64t-16t^2\geq 48[/tex]
[tex]0> 16t^2-64t+48[/tex]
Divide both sides by 16.
[tex]0> t^2-4t+3[/tex]
[tex]0> t^2-t-3t+3[/tex]
[tex]0> t(t-1)-3(t-1)[/tex]
[tex]0>(t-1)(t-3)[/tex]
Related equation is [tex](t-1)(t-3)=0[/tex]. Zeroes are t=1,3. These two number divide the number line is three parts. (-∞,1),(1,3),(3,∞)
[tex]0>(t-1)(t-3)[/tex] inequality is true for only (1,3).
It is only possible when t lies in the interval (1,3).
Therefore, the ball will be more than 48 feet above the ground between 1 and 3 seconds.
3) x-intercept = -3, y-intercept = 1
Y=-3/1 x -3
Would that be how I set it up in the formula form?
Answer:
y = 1/3x+1
Step-by-step explanation:
Use the intercepts to find the slope
(-3,0) and (0,1)
(1-0) / (0-(-3)) = 1 / 3
Plug it into the equation
y= 1/3x + 1
Order these numbers from largest at the top, to smallest at the bottom.

reorder answers
Answer:
2.45x10^3
3.13x10^1
4.987
1.157x10^-4
Step-by-step explanation:
I have assumed that 1.1.57 = 1.157 and the same with the second and third numbers.
3.13 * 10^1 = 31.3
1.157 * 10^-4 = 0.0001157

Step-by-step explanation:
nxz - f = 3f
Solve for x
Answer:
x = 4f/nz
Step-by-step explanation:
nxz - f = 3f solve for x
nxz = 3f+f
Factor of nxz is x(nz)
x(nz) = 3f+f
x(nz) = 4f
MUltiply both side with 1/nz and you get
x = 4f/nz

What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
Two ratios or fractions are equal when an equation or a declaration to that effect is utilised.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
when x= 2/3, y=6.
Using constant proportionality
y = kx
k= y/x
k = 6 / (2/3)
k = 6 x 3/2
k = 9
Now, k= y/x
9 = y/ ([tex]10\frac{1}{3}[/tex])
9 = y / (31/ 3)
y = 9 x 31/3
y = 93
Hence, the value of y is 93.

O All sides are congruent.
O Corresponding angles are congruent.
The triangles are similar.
O Corresponding sides are proportional.
Answer:
Corresponding angles are congruent, corresponding sides are porportional, and the triangles are similar.
Step-by-step explanation:
Since angles on a triangle add up to 180 degrees, we can figure out that both triangles' angles are 55, 35, and 90. That means the triangles are similar, corresponding sides are porportional, and also means the corresponding angles are congruent. The 4th one cannot be guaranteed, as the triangles could be of different sizes.
Is this graph a function?
Answer:
Depends; it is a function of y because each y value maps out to only 1 x value, but it is not a function of x, because for x = 3 y maps out to infinite values.

Tres aviones salen a la misma hora de un mismo aeropuerto, el primero sale cada 8 dias, el segundo cada 10 dias, y el tercero cada 20 dias. Si salen el 2 de enero, ¿cuales seran las fechas proximas en que volveran a salir juntos? ( el año es de 365 dias)
Responder:
Después de 40 días (11 de febrero)
Explicación paso a paso:
Dado que :
El avión 1 sale cada 8 días
El avión 2 sale cada 10 días
El avión 3 sale cada 20 días
Si todos se van el 2 de enero; La próxima fecha en que se irán juntos se puede obtener obteniendo el mínimo común múltiplo de los días de cada avión:
___8____10_____20
2 | _4____5______10
2 | _ 2____5______ 5
2 | _ 1 ____5______ 5
5 | _ 1 ____ 1 ______ 1
El mínimo común múltiplo es, por tanto;
2 * 2 * 2 * 5 = 40
Todos se irán juntos nuevamente después de 40 días:
(2 de enero + 40 días) = 11 de febrero
