ABCD is a rectangle.
Rectangle A B C D is shown. All angles are right angles. The length of A D is 5 and the length of D C is 12.
Use the diagram to answer the questions.
The length of AB is
.
The length of BC is
.
The length of AC is
.
Answer:
AB = 12 BC = 5 AC = 13
Step-by-step explanation:
opposite sides of a rectangle are congruent, therefore AB = DC = 12
and BC = AD = 5.
Now, AC is found by using the Pythagorean theorem.
So, [tex]AC^{2}[/tex] = [tex]AB^{2}[/tex] + [tex]BC^{2}[/tex]
= [tex]12^{2}+5^{2}[/tex]
= 144 + 25 = 169
AC = [tex]\sqrt{169}[/tex] = 13

Can someone help me understand where the positive 2 came from?
Answer:
4(-2)-(0)-2(-1)
a negative number multiplied by a negative number will always equal a positive number as the two negatives cancel each other out.
-2 multiplied by -1 equals positive 2
this is why the 2 is positive.

Three girls reeshma, salma abd mandip are playing a game in a cirvle of radius 5m. Distance from reeshma to salma is 6m, distance between salma and mandip is 6m, find the distance between mandip and reeshma
Answer:
9.6 m
Step-by-step explanation:
Given that :
Radius of circle = 5m
Using the labeled triangle :
Obtain OA:
OA = sqrt(Radius² - AR²)
AR =BM = 6/2 = 3
OA = sqrt(5² - 3²)
OA = Sqrt(25 - 9)
OA = Sqrt(16)
OA = 4
Area of triangle OSM
0.5 * 5 * SM = 0.5 * 4 * 6
2.5 * SM = 12
SM = 12 / 2.5
SM = 4.8
Distance RM = RS + SM
SM = RM
RM = 4.8 + 4.8
RM = 9.6 m

let g be the function given by g (x) = 3x^4 - 8x^3. At what value of x on the closed interval [ -2,2 ] does g have an absolute maximum
Answer:
When we have a function g(x)
We will have a maximum at x when:
g'(x) = 0
g''(x) < 0.
Now we start with:
g(x) = 3*x^4 - 8*x^3
The first derivation is:
g'(x) = 4*3*x^3 - 3*8*x^2
g'(x) = 12*x^3 - 24*x^2
We can rewrite this as:
g'(x) = x^2*(12*x - 24)
Now we want to solve:
g'(x) = 0 = x^2*(12*x - 24)
We have one trivial solution, that is when x = 0.
The other solution will be when the term inside of the parentheses is equal to zero.
Then we need to solve:
12*x - 24 = 0
12*x = 24
x = 24/12 = 2
Then g'(x) is equal to zero for x = 0, and x = 2.
Notice that both of these points are included in the interval [ -2,2 ]
Now we need to look at the second derivative of g(x):
g''(x) = 3*12*x^2 - 2*24*x
g''(x) = 36*x^2 - 48*x
Ok, now we need to evaluate this in the two roots we found before:
if x = 0:
g''(0) = 36*0^2 - 48*0 = 0
g''(0) = 0
Then we do not have a maximum at x = 0, this is a point of inflection.
if x = 2:
g''(2) = 36*(2^2) - 48*2 = 48
then:
g''(2) > 0
This is an absolute minimum.
Now let's look only at the interval [ -2,2 ]
We know that:
g''(0) = 0
g''(2) > 0
Then at some point, we should have g''(x) < 0 in our interval.
We need to find the first point such that happens, so let's try with the lower limit of the interval but with the first derivation, if g'(x) < 0, this means that the function is decreasing from that point on, then that point will be a maximum in our interval.
x = -2
g'(-2) = (-2)^2*(12*-2 - 24) = -192
And if we look at the function:
g'(x) = x^2*(12*x - 24)
We can easily see that it is negative unitl x = 0, and then it keeps being negative until x = 2.
So in the interval [ -2,2 ], the function g'(x) is always negative or zero, this means that in the interval [ -2,2 ], the function g(x) is always decreasing or constant.
Then the absolute maximum of g(x) in the interval [ -2,2 ] will be x = -2
this means that:
g(-2) ≥ g(x) for all x ∈ [ -2,2 ]

4 children bring games to Tony's party. Each child brings the same number of games. Two more games are needed to reach 30 games. How many games does each child brings?
Answer:
7 games per child.
If two more games are needed for 30, then that means there are 28 games there. You then divide 28 by the number of kids, 4, so 28÷4=7 games per kid.
There are 7 games per child brought to Tony's party.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings or to determine how many people are in each category after a fair distribution.
For example 4/2 = 2
We have been given that four kids bring games to Tony's birthday. Everyone brings the same amount of games. Two more games are required to achieve 30.
According to the given question, the required solution would be as:
If two more games are required to reach 30, then indicates there are 28 games available. Then you divide 28 by the number of children, 4, for a total of 28/4 = 7 games per child.
Hence, there are 7 games per child brought to Tony's party.

when adding and subtracting numbers do you add and subtract the denominator
Answer:
No, you don't.
Step-by-step explanation:
The denominator only changes if you're multiplying/dividing. You may need to create an equivalent fraction to add the fractions together, but you don't add or subtract the denominator.
Hope this helps! Have a great day!
Answer:
No, you adjust the numerator and denominator to a common denominator, then do the addition/subtraction operations with with the numerator, and finally reduce it to the lowest fraction.
Example:
1/3 + 3/4 = ?
change to a common denominator (12 works for 3 and 4)
4/12 + 9/12 = ?
add the 9 and 12
4/12 + 9/12 = 13/12
reduce to lowest form
12/12 = 1 1/12

What is the equation, in slope-intercept form, of the line parallel to -5x + y = 2 that passes through the point with coordinates (-2, 1)?
Answer:
y = 5x + 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
- 5x + y = 2 ( add 5x to both sides )
y = 5x + 2 ← in slope- intercept form
with slope m = 5
Parallel lines have equal slopes, then
y = 5x + c ← is the partial equation
To find c substitute (- 2, 1) into the partial equation
1 = - 10 + c ⇒ c = 1 + 10 = 11
y = 5x + 11 ← equation of parallel line
6. If F(x) = -6(2x2 + 5x) - 9, what is the value of F(-4)?
Answer:
-81
Step-by-step explanation:
-6(2x² + 5x) - 9
substitute -4 for 'x'
-6[2(-4)² + 5(-4)] - 9
-6[2(16) + (-20) - 9]
-6(32 - 20) - 9
-6(12) - 9
-72 - 9 = -81

What are the patterns in changing a fraction into a percent? I need this answer as soon as possible thankyou!
Answer:
See below.
Step-by-step explanation:
To change a fraction into a percent, divide the numerator by the denominator and multiply by 100%.
For example:
Example 1)
Change 1/2 into a percent.
1/2 = 0.5
0.5 * 100% = 50%
1/2 = 50%
Example 2)
Change 13/16 into a percent.
13/16 = 0.8125
0.8125 * 100% = 81.25%
13/16 = 81.25%
