The perimeter of a rectangle is 64 feet. The length is two more than double the width. Find the dimensions of the rectangle.
Answer:
Length = 22 ; width = 10
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Perimeter = 64 feets
Length = 2 + (2*width)
Let :
Length = l ; width = w
Perimeter = 2((2 + (2w)) + w)
64 = 2(2 + 3w)
64 = 4 + 6w
64 - 4 = 6w
60 = 6w
w = 60/6
w = 10
Width = 10
Length = 2 + (2*width) = 2 + (2*10) = 2 + 20 = 22

ax + ay + bx + by/
x+y
Answer:
a + b
Step-by-step explanation:
ax + ay + bx + by
a(x +y) +b(x + y)
(a + b) ( x + y)
therefore (a + b) ( x + y) divide x+y
x + y is canceled out both in the denominator and numerator
= a+b
Answer:
a + b

how do i know if a slope is negative
Answer:
A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls.

A statistical procedure that estimated regression equation coefficients that produce the lowest sum of squared differences between the actual and predicted values of the dependent variable is called .
Answer:
Ordinary least squares
Step-by-step explanation:
The ordinary least squares means the estimations that done for parameters in a regression model by lowering the sum of the square residuals. It also predicted the coefficient of the regression equation that generate the actual and the expected values of the dependent variable is known as ordinary least squares

the graph shows the cost of some taxi journeys. work out a formula for C in terms of n.
Given:
The graph of cost of taxi with respect to number of miles.
To find:
The formula for C in terms of n.
Solution:
In the given graph x axis represents the number of miles (n) and y-axis represents the cost of taxi (C).
From the given graph it is clear that, the line passes through the points (0,3) and (5,6). So, the equation of line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-3=\dfrac{6-3}{5-0}(x-0)[/tex]
[tex]y-3=\dfrac{3}{5}(x)[/tex]
Adding 3 on both sides, we get
[tex]y=\dfrac{3}{5}x+3[/tex]
Putting y=C and x=n, we get
[tex]C=\dfrac{3}{5}n+3[/tex]
Therefore, the required formula is [tex]C=\dfrac{3}{5}n+3[/tex].

Give the equation of a line that is perpendicular to
f(x)= 3x+1 and goes through the point (0, -6).
Answer: -1/3x - 6
Step-by-step explanation: perpendicular lines have opposite reciprocal slopes
original slope of 3 —-> -1/3
then our point is (0, -6) let’s plug that into y=-1/3x+b
-6 = -1/3(0)+b
b= -6
put it all together: y = -1/3x -6

What is the solution set of {x | x 5}?
1. the empty set
2. all real numbers
3. the numbers between -5 and 5
4. all numbers less than -5 and greater than 5
Answer:
3. the numbers between -5 and 5
Step-by-step explanation:
Let set A= [tex]\{x| x>-5\}[/tex] and set [tex]B=\{x | x<5\}[/tex].
The solution set of A and B is the solution set of A∩B
The solution set of A is all the real number x which is greater than -5.
The solution set of B is all the real number x which is less than 5.
Therefore, the solution set of A∩B is all the real numbers between -5 and 5.
Hence, option (3) is correct.
If p(x)= x^2 - 2root2x + 1, then p(3root2)= ?
Answer:
19 - 2^(7/4)√3 or
13.174 to nearest thousandth.
Step-by-step explanation:
I am interpreting this as x^2 - 2√(2x) + 1
p(3√2) = (3√2)^2 - 2√(2*3√2) + 1
= 18 - 2√(6√2) + 1
= 19 - 2* √6 * 2^1/4
= 19 - 2*√2*√3*2^1/4
= 19 - 2^(7/4)√3.
= 13.174 to the nearest thousandth.

Step-by-step explanation:
All you have to do in this question is to substitute what they are telling you.
First blank:
They told us that m is 0 so if we plug that into the equation we can get s.
[tex]2m+4s=16\\2(0)+4s=16\\4s=16\\s=4[/tex]
In this one if m is 0, s will have to be 4.
Second blank:
They told us that s is 3 so if we plug in that into the equation we can get m.
[tex]2m+4s=16\\2m+4(3)=16\\2m+12=16\\2m=4\\m=2[/tex]
In this one if s is 3, m will have to be 2.
Third blank:
They told us that m is -2 so if we plug that into the equation we can get s.
[tex]2m+4s=16\\2(-2)+4s=16\\-4+4s=16\\4s=20\\s=5[/tex]
In this one if m is -2, s will be 5.
Fourth blank:
They told us that s is 0 so if we plug into the equation we can get m.
[tex]2m+4s=16\\2m+4(0)=16\\2m=16\\m=8[/tex]
In this one if s is 0, then m will be 8.
How long is the light beam from the top of the lighthouse to the ground? Round to the nearest tenth. The light house is 25m tall and a boat is 180m from the base
Answer:
181.7m
Step-by-step explanation:
The set up is a right angled triangle with;
Height of the light house = 25m = opposite side
The distance of the boat from the base = 180m = Adjacent
The distance of the light beam from the house = Hypotenuse = x
Using pythagoras theorem;
x² = 25²+180²
x² = 625+32400
x² = 33025
x = √33,025
x = 181.7m
Hence distance of the light beam from the top of the lighthouse to the ground is 181.7m to the nearest tenth
2 numbers are in ratio 2 is to 4 if their sun is 147 then what i the largest number?
Answer:
The larger number is 98
Step-by-step explanation:
Let the numbers be a and b
a/b= 2/4
4a = 2b ------- 1
a + b = 147 -----2
a= 147 - b -------3
Substitute equation 3 into 1
4(147 -b) = 2b
588 - 4b = 2b
588= 2b + 4b
588 = 6b
b= 588/6
b= 98
Substituting b= 98 into 1
4a = 2(98)
4a = 196
a= 49
The larger number is 98
