The length of a rectangle is three more than its width. If the perimeter is 46 feet, what are the dimensions of the rectangle?
O 10 by 7
0 43 by 3
O 12 by 11
O 13 by 10
Answer:
13 BY 10
Step-by-step explanation:
let width be z
length be z+3
perimeter=46
2(l+b)=46
z+z+3=23
2z=20
z=10
z+3=l=13

Peter left city a at 9:00 am towards city b at an average speed of 50 mph. Thirty minutes later Emily also leaves city a towards city b. What should be the average speed of Emily if she has to catch-up with peter at 11:30 am?
Answer:
62.5 mph
Step-by-step explanation:
Given that :
Peter :
Speed = 50mph
Start Time = 9 a. M
Emily :
Start time = 9:30
Speed = x
In other to catch up at 11:30 :
Peter (11:30 - 9:00) = 2hours 30 minutes = 2.5 hrs
Total distance moved by Peter :
Speed * time = 50 * 2.5 = 125miles
For Emily to cover 125 miles in (11:30 - 9:30) = 2 hours
Speed = distance / time
Speed = 125 miles / 2 hours
Speed = 62.5 miles per hour

!!!PLEASE ANSWER, ASAP!!!An adult takes 800 mg of ibuprofen. Each hour, one fourth of the medicine leaves the system. Write the exponential equation that models this situation.
Given:
An adult takes 800 mg of ibuprofen.
Each hour, one fourth of the medicine leaves the system.
To find:
The exponential equation that models this situation.
Solution:
The general exponential model is
[tex]y=a(1-r)^x[/tex] ...(i)
where, a is initial value r is decreasing rate and x is time period.
According to the question,
Initial value of medicine = 800 mg
Decreasing at the rate of [tex]\dfrac{1}{4}[/tex] per hour.
Putting a=800 and [tex]r=\dfrac{1}{4}[/tex] in (i), we get
[tex]y=800(1-\dfrac{1}{4})^x[/tex]
[tex]y=800(\dfrac{4-1}{4})^x[/tex]
[tex]y=800(\dfrac{3}{4})^x[/tex]
Therefore, the required exponential equation that models the given situation is [tex]y=800(\dfrac{3}{4})^x[/tex], where, y is ibuprofen (in mg) after x hours.

Tres compañías aportan capitales para hacer una investigación la estrella aporta 509000 724 flechabús la mitad de lo que aporta la estrella más 23184 y la terminal 104208 menos que lo que aporta flechabús cuánto aportan en total cada uno de los tres juntos
Answer:
En total, se invirtieron $960,000 por parte de las tres empresas.
Step-by-step explanation:
Para resolver cuánto dinero aportaron en total las tres empresas, es necesario determinar la cantidad de dinero que cada una de ellas aportó en forma particular. Así:
La Estrella: 509,000
Flechabus: (509,000 / 2) + 23,184
254,500 + 23,184
277,684
La Terminal: ((509,000 / 2) + 23,184) - 104,208
277,684 - 104,208
173,476
Ahora bien, para determinar el total invertido se requiere sumar dichos montos: 509,000 + 277,684 + 173,476 = 960,160
Así, en total, se invirtieron $960,000 por parte de las tres empresas.

Maricela needs to write instructions for how to construct a regular hexagon inscribed in a circle. She begins by writing the following two steps:
Step 1: Start by drawing a cirlce using compass.
Step 2: Mark a point on the circle.
What is the best statement for Maricela to write for Step 3?
A. Using a straighedge, draw a segment that passes theough the marked point to the center of the circle.
B. Without changing the width of the compass, put the compass point ar the marked point, then draw and arc that intersects the circle in two places.
C. Using a straightedge, deaw a line segment from the center of the circle through the marked point, then extend the segment and label a point outside the circle.
D. Widen the radius of the compass to the width of the diameter, then place the compass point at the marked point and draw an arc that intersects the circle in one place.
Answer: The answer is B, without changing the width of the compass, put the compass point at the marked point, then draw an arc that intersects the circle in two places.

How do you write intervals of increase and decrease?
Answer:
add one per interval
Step-by-step explanation:
an example would be:
+1
+2
+3
or:
+4
+8
+12
Answer:
As part of exploring how functions change, we can identify intervals over which the function is changing in specific ways. We say that a function is increasing on an interval if the function values increase as the input values increase within that interval. Similarly, a function is decreasing on an interval if the function values decrease as the input values increase over that interval. The average rate of change of an increasing function is positive, and the average rate of change of a decreasing function is negative.
The image below shows examples of increasing and decreasing intervals on a function.

The equation below describes a linear function. y=−2(x+1)+4 The range of the function is {−4,−2,4} . What is the domain of the function
9514 1404 393
Answer:
{-1, 2, 3}
Step-by-step explanation:
We need to find the values of x that correspond to these y-values.
{-4, -2, 4} = -2(x +1) +4 . . . substitute the range values for y
{2, 1, -2} = x +1 -2 . . . . . . .divide by -2
{2, 1, -2} = x -1 . . . . . . . . . simplify
{3, 2, -1} = x . . . . . . . . . . . add 1
The domain of the function is {-1, 2, 3}.

What is a Parabola?A Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. A parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line
The equation of the parabola is given by
( x - h )² = 4p ( y - k )
y = a ( x - h )² + k
where ( h , k ) is the vertex and ( h , k + p ) is the focus
y is the directrix and y = k – p
The equation of the parabola is also given by the equation
y = ax² + bx + c
where a , b , and c are the three coefficients and the parabola is uniquely identified
Given data ,
Let the parabolic equation be represented as f ( x )
Now , the value of f ( x ) = y
where y = -4x²
The equation y = -4x² represents a parabola that opens downwards (since the coefficient of x² is negative).
The vertex of this parabola is at the origin (0,0), since the coefficient of x is zero. The axis of symmetry is the y-axis, since the parabola is symmetric about this line.
Hence , the equation is y = -4x²
