Step-by-step explanation:
6.25 x 20 = 125
(A) Find the dimensions of the rectangle with area 324 square inches that has minimum perimeter, and then find the minimum perimeter.
A = L*w
324 = L*w
324/w = L
P = 2*( L + w)
= 2 * ( 324/w + w)
= 648/w + 2w
= (648 + 2w^2)/w

Answer:
46
240
Step-by-step explanation:
Substitute the given values for the variables, and evaluate the expressions.
1.
n = -5; m = 4
2n² - m = 2(-5)² - 4 = 2(25) - 4 = 50 - 4 = 46
2.
H = 60; Q = 40; V = 10
HQV/100 = (60)(40)(10)/100 = 6(4)(10) = 240
Answer:
46
240
Step-by-step explanation:
1) Put n = -5 and m = 4 into the equation, you'll then have;
2(-5)²-4
2(25)-4
50-4=46
2) Put H=60, Q=40 and V=10 into the equation, then you'll have that;
(60×40×10)/100
24000/100
=240

Answer:
y < 5
Step-by-step explanation:
Subtract 22 from both sides.
7y < 5y + 12 - 2
7y < 5y + 12 − 2
2 Simplify 5y + 12 - 25y + 12 − 2 to 5y + 105y + 10.
7y < 5y + 10
7y < 5y + 10
3 Subtract 5y5y from both sides.
7y - 5y < 10
4 Simplify 7y - 5y7y − 5y to 2y.
2y<10
Divide both sides by 22.
y < 10/2
Then Simplify 10/2 to 5
y < 5

Step-by-step explanation:
The equations of the lines given in the graph will be,
y = x - 1
y = -2x +4
y = 4
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
For line one the points are:-
( 3,2 ) and ( 1,0)
Slope = ( 0 -2 ) / ( 0 - 3 )
Slope = 1
The equation will be,
y = x + c
0 = 1 + c
c = -1
For line two the points are:-
(0,4) and (2,0),
Slope = ( 0 - 4 ) / ( 2 - 0 )
Slope = -2
The y-intercept will be,
y = mx +c
y = -2x + c
c= 4
The equation can be written as:-
y = -2x +4
The equation of the line parallel to x-axis is,
y = 4

The average rate of change of function f(x) from x = a to x = b is
[tex] \dfrac{f(b) - f(a)}{b - a} [/tex]
Here we have
a = -1
b = 2

f(b) = f(2) = 64
[tex] \dfrac{f(b) - f(a)}{b - a} = [/tex]
[tex] = \dfrac{f(2) - f(-1)}{2 - (-1)} = [/tex]

Hi can u help me with my hw
Answer:
c) difficult
Step-by-step explanation:
1) w = 14/3
Steps:
1) Multiply the numbers
5w - 8/3 = 4w + 2
2) Add 8/3 to both sides of the equation
5w - 8/3 + 8/3 = 4w + 2 + 8/3
3) Simplify
A. Add the numbers
5w = 4w + 2 + 8/3
B. Add the numbers
5w = 4w + 14/3
4) Subtract 4w from both sides of the equation
5w - 4w = 4w +14/3 - 4w
5) Simplify
A. Combine like terms
1w = 4w + 14/3 - 4w
B. Multiply by 1
w = 4w + 14/3 - 4w
C. Combine like terms
w = 14/3

find the length of segment AB
Answer:
E. 214
Step-by-step explanation:
Since the other angles of the triangle are congruent, and separated creates 2 right triangles, this means that segment (because i cant put the actual names for some reason) A to F and segment F to B are equal
8x - 37 = 5x + 17
3x = 54
x = 18
Now substitute to check
8(18) - 37 = 5(18) + 17
107 = 107
So if this is true, to find the segment A to B, just add segments A to F and F to B together
107 + 107 = 214
The length of segment AB is 214
In the figure, parallelogram PQSR and Triangle PQT are standing
on the same base and between, the same parallel lines. The
area of triangle PQT is 50 cm?. Find the area of Triangle PRS.
Answer:
50 cm²
Step-by-step explanation:
We know that PQRS is a paralleogram so we know that RS = PQ.
We also know that ΔPQT and ΔPRS has the same height . The the area is the same, from the area of that we can get 50 cm²
identify an equation in point-slope form for the line perpendicular to y = 2x + 8 that passes through (-3,9)
Answer:
y - 9 = m(x + 3)
Step-by-step explanation:
Given a line whose slope is m, the slope of a new line that is perpendicular to the given line is the negative reciprocal of m: -1/m
Given y = 2x + 8, we see that the slope is 2 and figure that the negative reciprocal of that is -1/2. This is the slope of the desired perpendicular line.
We can write the equation of this perpendicular line most easily by using the point-slope form y - k = m(x - h), where (h, k) represents the point:
y - 9 = m(x + 3)
Car rental company A charges $15 to rent a car plus $2.30 per hour. Car rental company b charges $22 to rent a car plus $1.90 per hour. When would the cost of renting a car from company A be the same as renting a car from company B?
Answer: The cost of renting a car from Company A be the same as renting a car from company B in 17.5 miles
Step-by-step explanation:
y=2.30x +15
y=1.90x +22
0.4x +7 Divide 0.4 from both sides
x=17.5
y=2.30(17.5)+15
y=40.25+15
y=40.25-15
y=25.25

Answer:
1 2/3, and -1 2/3
Step-by-step explanation:
Im wondering how old you are, and since you seem young just based off the math you're asked to do, please listen to the explanation and teach yourself this. This skill in particular is SOOO important to the rest of the math world. So since your number line is already divided into thirds, there are two ways you could find your answer. One, you can count 5 thirds away from zero, or two, you could simplify 5/3 from an improper fraction to a mixed number (1 2/3) and find your spot from there. "and the opposite" means not only the point 5/3 Away from zero on the Right, but also 5/3 away from zero on the Left. start from zero again and count the same amount away but in the opposite direction. With negatives it can help to think of how all numbers are just descriptions of how far left or right a number is from zero. i hope this helped lol, negatives are a confusing batch, but they're so so important to math as a whole.
Please help with this dilation!

The FM radio station KAMB broadcast from an antennae atop a 150 meter tall radio tower at a frequency of 90 MHz with a total radiated power of 40 kilowatts. Neighbors have complained about problems they attribute to excessive radiation from the tower, but the city engineer who measured the radiation level near the base of the tower found it to be well below the accepted standard. You have been hired by the HOA to assess the engineer's report. You know a few things about electromagnetic radiation and therefore conclude that we must find the optimum place on the ground to measure the maximum radiation emitted from the antennae. From your extensive knowledge in physics, you know that the intensity of radiation, I, is given by the formula:
I=12/32π*Psin2(θ)/r^2
where P is the power output, r is the distance from the top of the tower to the point on the ground, and θ is the angle measured from the tower to r.
Find the distance R from the base of the tower to the optimum location for taking the radiation reading. (m)
What is the maximum radiation reading from the ground in kw/m^2
If the city code requires that electromagnetic radiation be under 200 microwatts per square meter, is this antenna operating within city code? Yes or No
Answer: 150 m, 5.305*10^-5 kW/m^2, No
Step-by-step explanation:
See attachment, hope this helps
Using the radiation intensity formula we will have to:
a) [tex]150 m[/tex]
b) [tex]5.305*10^{-5} kW/m^2[/tex]
c)No
From the data informed, we have:
[tex]h=150m\\P=40KW[/tex]
Using the given formula and performing some mathematical operations:
[tex]I=\frac{12Psin^2(\theta)}{32(\pi)r^2} \\I= \frac{12(40)(R/r)^2}{32(\pi)r^2} \\= \frac{15R^2}{r^2\pi } \\= \frac{15R^2}{(R^2+150^2)^2\pi} \\[/tex]
deriving the given equation, we will have:
[tex]=\frac{(R^2+150^2)^22R-R^2(2(R^2+150^2))2R}{(R^2+150^2)^2}[/tex]
So from this equation we have that the answer of the letter A corresponds:
[tex]R=150[/tex]
For letter B we will have to develop this equation:
[tex]I= 5.30X10^{-5}[/tex]
As for the letter C, when converting the value found, it should give 200 microwatts, which is false.
