Answer:
The side length is 62 meters
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
3844 m^2 = s^2
Take the square root of each side
sqrt( 3844 m^2) = sqrt(s^2)
62 m= s
The side length is 62 meters

A right rectangular prism is shown.
To the nearest thousandth of an inch, what is the length of the diagonal, dd?
Answer:
15.56 in.
Step-by-step explanation:
i'm pretty sure i did it right, but im not sure. i haven't done geometry in like over 2 years.
find the hypotenuse of the triangle with 7 in. and 12 in. as your legs with the Pythgorean theorem (a^2 + b^2 = c^2, c equals the hypotenuse)
use that number you just got (I got [tex]\sqrt{193}[/tex]) and use it as one leg, and 7 in. as the other leg, with d as your hypotenuse
use the Phythagorean theorem again to find d, andddd... you've got your answer!
Length of diagonal 'd' of the right rectangular prism given in the picture will be 14.765 inches.
Pythagoras theorem: Pythagoras theorem is applicable in a right triangle. Pythagoras theorem is given by the expression,(Hypotenuse)² = (Leg 1)² + (Leg 2)²
By applying Pythagoras theorem in right tringle ΔCBE,
(CE)² = (BC)² + (BE)²
(CE)² = 5² + 12²
CE = √169 = 13 inches
Similarly, apply Pythagoras theorem in right triangle ΔDCE,
(DE)² = (CD)² + (CE)²
d² = 7² + (13)²
d² = 49 + 169
d = √218
d = 14.7648
d ≈ 14.765 inches
Hence, measure of diagonal 'd' will be 14.765 inches.

5(r + 3) = 3r + 35.
What is the answer and please show how you got it
Answer:
r =10
Step-by-step explanation:
5(r + 3) = 3r + 35.
Distribute
5r+15 = 3r+35
Subtract 3r from each side
5r+15-3r = 3r+35-3r
Combine like terms
2r +15 = 35
Subtract 15 from each side
2r+15-15 =35-15
2r = 20
Divide by 2
2r/2 =20/2
r =10

Based on the regression output, which of the following is the predicted time, in minutes, that it took to gather the items if the order has 22 items?
Answer:
The predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes
Step-by-step explanation:
Regression Output :
Predictor Coefficient
Constant 3.0979
Square root of items 2.7633
R.sq.- 96.7%
So, with this data the regression equation is,
[tex]\hat{y}=3.0979+2.7633x[/tex]
Now we are supposed to find the predicted time, in minutes, that it took to gather the items if the order has 22 items
Substitute x =22 in equation
[tex]\hat{y}=3.0979+2.7633(22)[/tex]
[tex]\hat{y}=63.8905[/tex]
Hence the predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes

2. Write a quadratic equation with roots (-2,0) and (4,0) that has a minimum value
of -36
Answer:
f(x) = 4*(x+2)*(x-4) factorized formula
f(x) = 4x^2 - 8x - 32 polynomical formula
Step-by-step explanation:
Lets assume the factorized formula of a quadratic function:
f(x) = a*(x-x1)^2 * (x-x2)^2
where "a" is a coefficient and x1, x2 are the roots of the function. Then replacing the given roots:
f(x) = a*(x+2)*(x-4)
because its told us that -36 is the minimum value of the function we can say that its concave, then this value is actually the component in the Y axis of the vertex. To find the component in the X axis of the vertex we have to make the adding between the roots and divide this value by 2, this last is because a quadratic function is a symetrical function. Lets call the component at the X axis of the vertex as Xv, then:
Xv=(x1+x2)/2
Xv=(-2+4)/2
Xv=1
Therefore now we have a point of the function and its P=(1,-36) this point is the vertex of the function too.
Now the last thing to do is to find the value of the coefficient "a". We can find it by replacing the point of the vertex obtained before.
-36 = a*(1+2)*(1-4)
-36 = a*(3)*(-3)
-36 = a*(-9)
4 = a
Finally the equation is:
f(x) = 4*(x+2)*(x-4)
if we expand this function we find the polynomical form of this function
f(x) = 4x^2 - 8x - 32
Simplify the equation

A. A positive coefficient for x^2 & the equation set equal to 0
B. Factor and cancel
C. Distribute like terms
D. There is no such thing as a quadratic equation
Answer:
Answer A makes the most sense by far.
Step-by-step explanation:
Answer A makes the most sense by far. However, strictly speaking, the coefficient of x^2 does not have to be positive if we're using the quadratic formula. Using some other approach, such as factoring, obtaining a positive coefficient for x^2 is helpful.

x-intercept=3, y-intercept=-4 put into slope intercept form
y = mx + c
y intercept= (0,-4) , x intercept = (3,0)
m = (y2-y1)/(x2-x1)
m = (0-(-4))/(3-0)
m = 4/3
0 = (4/3)(3)+ c
c = -4
Thus, the equation is y = 4/3 x -4

Find r when y=7
Find y when r=4.23
Step-by-step explanation:
2.3r - 7 + 6 = 21
2.3r - 1 = 21
2.3r = 22
r = 22/2.3
r = 9.6
2.3(4.23) - y + 6 = 21

The cost of her new bracelet. The cost of her old
bracelet is $18. Need help what Is this solution
Answer:
the answer is $12
Step-by-step explanation:
to get the answer you would multiply 18 by 2/3 or you can divide by 3 then multiply what you get from dividing by 3 by 2.
version 1: 18(2/3) = ?
12
version 2: 18/3=?
6 you want to multiply by to because that is 1/3 of the original price
6(2) = 12
