Trong cơn bão số 9 vừa qua. Một cột điện cao 9m bị gió bão làm gãy ngang thân, ngọn của cột điện chạm đất cách gốc 3m. Hỏi điểm gãy cách gốc bao nhiêu mét?
AB=9m and BC=3m
Using Pythagoras theorem, In ΔABC
(AC)² +(AB)² +(BC)²
⇒(AC)² =(9)² + (5)²
⇒(AC)² =81 + 25
⇒(AC)² =106
⇒AC=10.3m
=AC+CB=10.3+3=13.3m
I need help with this please
Answer:
the answer is 46.278
Step-by-step explanation:
the formula to find perimeter is πR + d
3.142 × 9 = 28.278 (that's pi times your radius)
28.278 + 18 = 46.278 (add your diameter to the previous problem to get the perimeter)

5/3 (a)(x)(b)(xx)(c)(a^3)
5/3 (a^4)(b)(c)(x^3)
-2.07 (a^2)(x^3)(a^2)(b)
-2.07 (a^4)(b)(x^3)
-7/6 (a^2)(x^3)(c)(a^2)(b)
-7/6 (a^4)(b)(c)(x^3)
Notice that only the first and third monomials (when simplified) contain the exact same variables with the same exponents. Therefore, those are the only two monomials we can add together.
(10/6 - 7/6)(a^4)(b)(c)(x^3) - 2.07(a^4)(b)(x^3)
(1/2)(a^4)(b)(c)(x^3) - (2.07)(a^4)(b)(x^3)
(a^4bx^3)(1/2c - 2.07) --- Factored form
Since this expression has two terms, it is a binomial.
Hope this helps!! :)

1/10p=p-279
1/2p =p-155
Question 1: Given [tex]1/10p=p-279[/tex] find [tex]p[/tex]
Answer:
[tex]p=310[/tex]
Step-by-step explanation:
1. Subtract [tex]p-279[/tex] from both sides: [tex]279-\frac{9p}{10}=0[/tex]
2. Subtract [tex]279[/tex] from both sides: [tex]\frac{9p}{10}=-279[/tex]
3. Multiply both sides by reciprocal [tex]\frac{10}{9}[/tex]: [tex]p=310[/tex]
Question 2: Given [tex]1/2p=p-155[/tex] find [tex]p[/tex]
Answer:
[tex]p=310[/tex]
Step-by-step explanation:
1. Subtract [tex]p-155[/tex] from both sides: [tex]155-\frac{p}{2}=0[/tex]
2. Subtract [tex]155[/tex] from both sides: [tex]-\frac{p}{2}=-155[/tex]
3. Multiply both sides by reciprocal [tex]\frac{2}{1}[/tex]: [tex]-p=-310[/tex]
4. Multiply both sides by [tex]-1[/tex]: [tex]p = 310[/tex]

A rectangular garden is 15 feet wide. Its length is 4 feet more than twice the width. What is the area of the garden?
Step-by-step explanation:
l = length
w = width = 15 ft
l = 2×w + 4 = 2×15 + 4 = 30 + 4 = 34 ft
the area of a rectangle is
area = l × w = 34×15 = 510 ft²

The product of the Expression is 3/ (a-2).
What is Expression?In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows:
(Number/variable, Math Operator, Number/variable) is an expression.
We have,
(2a - 7)/ a x (3a²)/ (2a² -11a + 14)
Now, simplifying the expression as
(2a - 7)/ a x (3a²)/ (2a² -11a + 14)
= (2a - 7)/ a x (3a²)/ (2a² -7a - 4a + 14)
= (2a - 7)/ a x (3a²)/ a (2a -7) -2 (2a- 7)
= (2a - 7)/ a x (3a²)/ (a- 2)(2a-7)
= 3a² / a(a-2)
= 3/ (a-2)
Thus, the product is 3/ (a-2).

How many cars do the two dealerships sell in total?
if the sum of interior angles of a polygon is 30 right angles how many sides does the polygon
Answer:
17 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here sum = 30 × 90° = 2700° , then
180° (n - 2) = 2700° ( divide both sides by 180° )
n - 2 = 15 ( add 2 to both sides )
n = 17
Answer:
17 sides
Step-by-step explanation:
-Let the number of sides of the polygon be n
The sum of the interior angles of a polygon of n sides is.180° (n−2)
The sum of interior angles =30×90°
30×90° =180°(n−2)
15=n−2
n=17

Use deductive reasoning to select a valid conclusion. If a quadrilateral is a rhombus, then it is also a parallelogram. Quadrilateral ABCD is a rhombus.A. Quadrilateral WXYZ is a rhombusB. No valid conclusionC. Quadrilateral ABCD is a parallelogramD. Every quadrilateral is a rhombus
Answer:
No valid conclusion
Step-by-step explanation:
- All rhombuses are parallelograms
- Not all parallelograms are rhombuses because a rhombus has four equal-length sides and a parallelogram has equal opposite sides.
- all squares are rhombuses but not all rhombuses are squares because a square has 4 right angles (90 degrees) and a rhombus has equal opposite angles
what is the equation
[tex]y = {(x - 3)}^{3} [/tex]
Step-by-step explanation:
The graph is indeed cubic and because y is 0 at 3 that means the graph is shifted to the right 3 units, so to write that as an equation we put -3 in the parentheses with the x. Also because it's a cubic graph the domain and range is infinite. If you read the statement above the chart it says a continuous graph. the chart is there to help identify the type of graph not to identify the domain and range

4(a+x)-b=16 solve for the variable x (pls help me)
Answer:
x = [tex]\frac{16+b-4a}{4}[/tex]
Step-by-step explanation:
4(a + x) - b = 16 ( add b to both sides )
4(a + x) = 16 + b ← distribute parenthesis on left side
4a + 4x = 16 + b ( subtract 4a from both sides )
4x = 16 + b - 4a ( divide both sides by 4 )
x = [tex]\frac{16+b-4a}{4}[/tex]
