Hello! Remember you have to write complete questions in order to find good and exact answers. Here I'll assume that you need a relationship between D and N. So we know some facts:
As N increases, then D decreasesSo this is an inverse relationship. We can write this as:
[tex]D\propto \frac{1}{N} \\ \\ \\ \boxed{D=k\frac{1}{N}} \\ \\ \\ \text{Where k is a positive constant}[/tex]
Since N lies in the denominator, as it increases then D will decrease. So this is a correct relationship
Which point is on the circle centered at the origin with a radius of 5 units?
Distance formula: (x2 – x2)2 + (v2 - Yo)?
(2, 721)
(2, V23)
(2, 1)
(2,3)
Answer:
(2,√21)
Step-by-step explanation:
The circle centered at the origin has equation:
[tex] {x}^{2} + {y}^{2} = 25[/tex]
Any point that satisfies this equation lie on this circle.
When x=2, we substitute and solve for y.
[tex] {2}^{2} + {y}^{2} = 25 \\ 4 + {y}^{2} = 25 \\ {y}^{2} = 25 - 4 \\ {y}^{2} = 21[/tex]
Take square root to get:
[tex]y = \pm \sqrt{21} [/tex]
Therefore (2,-√21) and (2,√21) are on this circle.
From the options, (2,√21) is the correct answer
Answer:2, square root of 21 just took the test!

What is s in 2m+4s=16 if m=-2
Answer:
s = 5
Step-by-step explanation:
2m + 4s = 16
Step 1: Plug in -2 for m
2(-2) + 4s = 16
-4 + 4s = 16
Step 2: Solve for s
-4 + 4s + 4 = 16 + 4
4s / 4 = 20 / 4
s = 5
Answer: s = 5
Answer:
s= 5
Step-by-step explanation:
s= 5
m= - 2
2m + 4s= 16
Replace the m with the value it is in brackets. Remember brackets mean to multiply.
2(-2) + 4s= 16
-4 + 4s= 16
Carry over the -4 and make s the subject.
4s= 16 - - 4
4s= 16 + 4
4s= 20
s= 20/4
s= 5
Therefore s= 5
To check if the answer was correct, replace the s and m with the value it is in brackets. s= 5; m= 2
2(-2) + 4(5)= 16
-4 + 20 = 16
Therefore s= 5 and the answer is correct!
why does an exponent represent exponential decay instead of growth?
The exponential e is used when modeling continuous growth that occurs naturally such as populations, bacteria, radioactive decay, etc.
Explanation
We can think of e like a universal constant representing how fast we could possibly grow using a continuous process. And, the beauty of e is that not only is it used to represent continuous growth, but it can also represent growth measured periodically across time.
The exponential e will be used in situations of continuous growth or decay. The following formula is used to illustrate continuous growth and decay. If a quantity grows continuously by a fixed percent, the pattern can be depicted by this function.
[tex]A = Ao e^k^t[/tex]
In case of exponential decay, k is less than 0.
Find the rate of change of the function
15x - 5y=20
Answer:
3
Step-by-step explanation:
⇒15x-20=5y
⇒(15x-20)/5=y
⇒3x
The rate of change of the function is 3
m = 3how to find the rate of change of the functionTo find the rate of change of the function 15x - 5y = 20, we need to solve for y in terms of x and then determine the coefficient of x, which represents the rate of change.
Let's solve the equation for y:
15x - 5y = 20
Subtract 15x from both sides:
-5y = -15x + 20
Divide both sides by -5:
y = (15/5)x - 4
Simplifying the equation:
y = 3x - 4
Now we can observe that the coefficient of x is 3. Therefore, the rate of change of the function is 3. This means that for every unit increase in x, the corresponding y-value increases by 3.

Which statement is true about the expression 12 minus 7 + 3?
The expression is equivalent to 12 minus (7 + 3) because of the associative property.
The expression is equivalent to 12 + 3 + (negative 7) because of the associative property.
The expression is equivalent to 12 minus 3 + 7 because of the commutative property.
The expression is equivalent to 12 + 3 + (negative 7) because of the commutative property.
Answer:
The expression is equivalent to 12 + 3 + (negative 7) because of the commutative property.
Step-by-step explanation:
The expression should be 12- 7 +3 = 8
The associative property allows you to put parenthesis anywhere in the equation as long it just addition and multiplication. In this question, we have subtraction(minus 7) so we can't use the associative property.
The commutative property allows you to move around a number as long as you didn't change its value or its group. Option C changes the value of the number so it's wrong. If you calculate it will give a different answer: 12-3+7=16
Option D didn't change the value so its the right answer.
Answer:
D is correct

An item was increased by 20% but then decreased by 25%. Calculate the percentage change and state if it was an increase or decrease.
Answer:
10% Decrease
Step-by-step explanation:
Let the number is 100.
Now, if we increase the number by 20%, the new number will be -
100 + (100 × 20%) = 100 + 20 = 120
The new number is 120.
Again, if we decrease the new number by 25%, the number will be -
120 - (120 × 25%) = 120 - 30 = 90
The new number is 90.
The change will be decreased by = (100 - 90) = 10
Percentage change = (10 ÷ 100) × 100 = 10%

2. Doug paid $39.95 for dinner. He left a 15% tip for the server. Which of the following is closest to
the tip left by Doug? *
Answer:
$5.99
Step-by-step explanation:
In this problem, Doug paid the following amount for the dinner:
[tex]p=\$39.95[/tex]
He also left a 15% tip.
Here we want to calculate what is the amount correspondant to the tip.
In order to find this value, we have to calculate the 15% of the value of the dinner, therefore we want to find
the 15% of 39.95$
The percentage (15%) can be rewritten as fraction:
[tex]15\% =\frac{15}{100}[/tex]
Therefore, the amount of the tip is
[tex]t=\frac{15}{100}p[/tex]
And substituting p, we find:
[tex]t=\frac{15}{100}(\$39.95)=\$5.99[/tex]
So, the tip is $5.99.
Answer: 5.99
Step-by-step explanation:
Change % to decimal
Then multiply
15% =.15
39.95 x .15 = 5.99

Changes made to your input should not affect the solution:

Step by step solution :
Step 1 :
Equation at the end of step 1 :
(-3x - 6) • ((3x2 - 6x) + 3)
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
-3x - 6 = -3 • (x + 2)
Step 4 :
Pulling out like terms :
4.1 Pull out like factors :
(3x2 - 6x + 3) = 3 • (x2 - 2x + 1)
Trying to factor by splitting the middle term
4.2 Factoring x2 - 2x + 1
The first term is, x2 its coefficient is 1 .
The middle term is, -2x its coefficient is -2 .
The last term, "the constant", is +1
Step-1 : Multiply the coefficient of the first term by the constant 1 • 1 = 1
Step-2 : Find two factors of 1 whose sum equals the coefficient of the middle term, which is -2 .
-1 + -1 = -2 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -1 and -1
x2 - 1x - 1x - 1
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-1)
Add up the last 2 terms, pulling out common factors :
1 • (x-1)
Step-5 : Add up the four terms of step 4 :
(x-1) • (x-1)
Which is the desired factorization
Multiplying Exponential Expressions :
4.3 Multiply (x-1) by (x-1)
The rule says : To multiply exponential expressions which have the same base, add up their exponents.
In our case, the common base is (x-1) and the exponents are :
1 , as (x-1) is the same number as (x-1)1
and 1 , as (x-1) is the same number as (x-1)1
The product is therefore, (x-1)(1+1) = (x-1)2
Final result :
-9 • (x + 2) • (x - 1)2

Find the area of trapezoid ABCD.
A) 80 cm2
B) 96 cm2
C) 104 cm2
D) 112 cm2
So you gotta break the trapezoid into 2 shapes, square and triangle.
Area of the square: 8 x 10 = 80 cm^2
Area of the triangle : 1/2 x base x height
base: 6
height: 8
therefore, 1/2 x 6 x 8 = 24 cm^2
24+80 = 104 cm^2
Therefore your answer is C
The area of the trapezoid ABCD should be option c [tex]104\ cm^2[/tex]
Calculation of the area of the trapezoid ABCD:Since
We know that
Area of the square= [tex]8 \times 10 = 80\ cm^2[/tex]
And,
Area of the triangle: [tex]1/2 \times base \times height[/tex]
Here
base = 6
height = 8
So, the area should be
[tex]= 1/2 \times 6 \times 8 \\\\= 24\ cm^2[/tex]
Now the area of trapezoid is
= 24+80
= 104
Hence, The area of the trapezoid ABCD should be option c [tex]104\ cm^2[/tex]
