Answer: what do you have to do
Step-by-step explanation:
How do you write greater than 35?.
The correct way to write greater than 35 is A > 35 where it tells that A having greater value than 35.
In mathematics,
→The greater than symbol (>) is used to indicate that one value is larger than another. For example, if we say "A > B," this means that the value of A is greater than the value of B.
→The less than symbol (<) is the opposite, it indicates that one value is smaller than another. For example, if we say "A < B," this means that the value of A is less than the value of B.
→The greater than or equal to symbol (≥) indicate that one value is larger than or equal to another. For example, if we say "A ≥ B," this means that the value of A is greater than or equal to the value of B.
→The less than or equal to symbol (≤) indicate that one value is smaller than or equal to another. For example, if we say "A ≤ B," this means that the value of A is less than or equal to the value of B.
These symbols are commonly used in mathematical expressions, equations, and inequalities.
To write "greater than 35" in mathematical notation, you would use the greater than symbol (>) followed by the letter 35. For example:
A > 35
This means that A is greater than 35.
Therefore, the correct way to write greater than 35 is A > 35 where it tells that A having greater value than 35.

What is the difference between the smallest 6 digit number with five different digits?.
The difference between the smallest 6-digit number with five different digits and the greatest 5-digit number with four different digits is 358.
The aim is to find the largest 5-digit number with four different digits and the smallest 6-digit number with five different digits, and then we need to find how many numbers are between these two values.
Let's start by finding the smallest 6-digit number with five different digits.
We know that 0 is the smallest digit that can not be used in the highest place value, so we will consider the next smallest digit, 1; therefore, it can be used in the highest place value.
Thus, we can create the required 6-digit smallest number with 0 and 1.
Hence, the smallest 6-digit number is 100234.
Now, we will discover the largest 5-digit number.
As we know, the largest digit is 9, which can be used anywhere. So, we will form the largest 5-digit number with the digit 9.
Thus, the largest 5-digit number is 99876.
Now, calculate the difference between these two numbers.
So, we can determine the difference between the smallest 6-digit number and the largest 5-digit number by subtracting the smallest from the largest.
Thus, we get,
⇒100234 - 99876
⇒358
Hence, 358 is the difference between the smallest 6-digit with five different digits and the largest 5-digit number with four different digits.

Is addition distributive?.
Yes, the distributive law is followed by the addition arithmetic operation.
Distributive Property of Multiplication Over Addition: This implies that the operation involves dividing or distributing the things. The distributive law applies to addition and subtraction arithmetic operation.
Distributive Property of Multiplication Over Addition : If we need to multiply a number by the sum of two numbers, we are using the distribution properties of multiplication and addition. The expresion for distributive property is: p( q+ r) = pq + pr ; p,q,r are three whole numbers.For example, let us multiply 8 by the sum of (20 + 3). Mathematically, we can represent this as 8 (20 + 3). First, use the distributive property to multiply each addend by 8. This is called distributing the number 8 over two addenda and then adding their products. That is, multiplication of 8(20) and 8(3) will be performed first, then addition. The result is 8 (20) + 8 (3) = 160 + 24 = 184.

What is the Pythagoras theorem?Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a² + b² = c².
Given here: A quadrilateral WXYZ with ∠Z=75 and ∠X=105
Let P be a point on ZW such that ZP=x and WP=4-x, then we form a right-angled triangle ΔZPY with tan 15°=x/PY
∴ PY=x/tan 15
=3.732x
Now using Pythagoras' theorem we get ZY as
[tex]\sqrt{13.927x^2+x^2} \\=\sqrt{14.92x^2}\\ =3.862641x[/tex]
Now let's connect the diagonal ZX we get the right triangle ZWX
Thus using Pythagoras' theorem we get
ZX=[tex]\sqrt{4^2+4^2}[/tex]
=4√2
Again let Q be an extension such that YQ=4-x & ∠YXQ=75°
Thus Sin 75=4-x/√N
√N=4-x/0.965923
squaring both sides we get N=(4-x)²/0.9330127........(1
Now using the Pythagoras theorem in ΔZYX we get
√N=
[tex]\sqrt{ZX^2-ZY^2} \\=\sqrt{32-14.92x^2} \\[/tex]
⇒N=32-14.92x²..,.......2)
Thus equation two values of N we get
(4-x)²/0.9330127=32-14.92x²
16-8x+x²=29.8564-13.920549x²
14.921x²-8x-13.856=0
Thus using the quadratic formula we get the value of x as
x= 8±29.85 /29.84
x=1.2684 (∵ Distance cannot be negative)
∴ Value of N=32-14.92×1.2684
N=13.075

No troll.
Answer:
A. See attached graph
B. [tex]\boxed{y = 0.12x^2+ 12}[/tex]
C. [tex]\boxed{160\;square\;feet}[/tex]
Step-by-step explanation:
Consider the figure which shows the cross-sectional view of the parabolic tunnel as viewed from the entrance
A. See attached graph
B. The parabola is drawn with the y-axis as the axis of symmetry.
The x-intercepts are at (-10, 0) and (10, 0)
The vertex is at (0, 12)
The vertex form equation for a parabola is
y = a(x - h)² + k
where (h, k) is the vertex - the (x, y) coordinates of the vertex
Here h = 0, k = 12
So the parabola equation is:
y = a(x - 0)² + 12
y = ax² + 12
To find a, plug in one of the x-intercepts, say (10, 0)
We get
0 = a(10)² + 12
0 = 100a + 12
100a = -12
a = -12/100 = -0.12
Therefore the equation of the parabola is
[tex]\boxed{y = 0.12x^2+ 12}[/tex]
C. The cross-sectional area is given by the formula:
D. To find the area of the parabola between x = -10 and x = 10 which forms the base of the parabola, you can use the formula
[tex]A = \dfrac{2}{3}bh\\\\[/tex]
where b is the base length and h is the height
Using the values for b = 20 and h = 12 we get
[tex]A = \dfrac{2}{3}\cdot 20 \cdot 12 = 160 \textrm { square feet}[/tex]
Using the definite integral, let's find the area between x = -10 and x = 10
I am not going through every step but leading you to the final answer
[tex]\int _{-10}^{10}\left(\:-0.12x^{2\:}+\:12\right)dx\\\\\\\textrm{We have}\\\\0.12\cdot \int _{-10}^{10}x^2dx=0.12\left[\frac{x^3}{3}\right]_{-10}^{10}\\\\[/tex]
[tex]=0.04\left[x^3\right]_{-10}^{10}\\\\= 80\\\\[/tex]
Therefore
[tex]-0.12\cdot \int _{-10}^{10}x^2dx = -80[/tex]
[tex]\int _{-10}^{10}12dx = \left[12x\right]_{-10}^{10} = 240[/tex]

year and let H represent the amount of money Henry has saved t weeks after the
beginning of the year. Write an equation for each situation, in terms of t, and
determine the number of weeks after the beginning of the year until Salma and Henry
have the same amount of money saved. PLEASE ANSWERR
Answer:
20 weeks
Step-by-step explanation:
Salma's savings can be represented by the equation S = 35 + 8t, where t is the number of weeks after the beginning of the year.
Henry's savings can be represented by the equation H = 95 + 5t
To determine the number of weeks after the beginning of the year until Salma and Henry have the same amount of money saved, we need to set the two equations equal to each other and solve for t:
35 + 8t = 95 + 5t
3t = 60
t = 20
So it would take Salma and Henry 20 weeks after the beginning of the year to have the same amount of money saved.
