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?
Answers
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
please help me with this. i have trouble finding the slopes in these problems.
Answers
Answer:
Slope = rise over run
So you start where the line hits the corner which is at (4,1) and until it hits a corner again which is at (7,5)
Step-by-step explanation:
The slope is 4/3
We can use points (4, 1) and (7, 5) and plug these values into the slope formula.
Let (x1, y1) = (4, 1)
(x2, y2) = (7, 5)
Use the slope formula:
m = (y2 - y1)/(x2 - x1)
m = (5 - 1)/(7 - 4)
m = 4/3
Therefore, the slope of the line is 4/3.

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).

what is the equation
Answers
[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

What is (5,3) and (6,7) in point slope form
Answers
Answer:
4
Step-by-step explanation:
( x1, y1 ) = ( 5, 3 )
Here,
x1 = 5
y1 = 3
( x2, y2 ) = ( 6, 7 )
Here,
x2 = 6
y2 = 7
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope = ( 7 - 3 ) / ( 6 - 5 )
= 4 / 1
Slope = 4
Answer:
(y−3)=4(x−5)
Step-by-step explanation:
Point slope form is defined by the formula [tex]y-y_{1}=m(x-x_{1})[/tex]
First, you find the slope using the slope equation [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]. (7−3)/(6−5)=4. Then you plug it back into the point slope form equation, and also plug in the points from y1 and x1.
This is also y=4x−17 in slope-intercept form or −4x+1y=−17 in standard form.

could someone help me with this question including a full explanation? thank you have a great day.
Answers
Step-by-step explanation:
just think about the basic formulas for area and perimeter of rectangles, and what pieces of information we already have directly.
area = length × width
perimeter = 2×length + 2×width = 136 m
=> length + width = 68 m
then we know
length = 2×width + 8
this we use as substitute in the simplified perimeter equation :
2×width + 8 + width = 68
3×width + 8 = 68
3×width = 60
width = 20 m
and therefore
length = 2×width + 8 = 2×20 + 8 = 40+8 = 48 m
and now we can calculate the area :
area = length×width = 48×20 = 960 m²
please consider that for a length or distance we use m (or other length units), for and area then m². for a volume then m³. as a basic unit for an area is a square. and for a volume a cube.
4(a+x)-b=16 solve for the variable x (pls help me)
Answers
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]

Jim's piano lessons are 30 minutes
longer than Suzanne's clarinet
lessons, Suzanne's clarinet lessons
are one-third the length of Pedro's
guitar lessons. If Pedro's guitar
lessons are 60 minutes long, how long
are Jim and Suzanne's lessons?
Answers
Answer:
Suzanne's lessons are 20 minutes long.
Jim's lessons are 50 minutes long.
Step-by-step explanation:
Jim's lessons = 30min longer than Suzanne's lessons
Suzanne's lessons = 1/3 of Pedro's lessons
Pedro's lessons = 60min
First, you need to find Suzanne's lesson time because her lessons are linked to Pedro's. Since you know Pedro's lesson is 60 minutes long and Suzanne's are a third of that you do: 60/3. Which is 20. So you know Suzanne's lessons are 20minutes long.
Next, since you know Suzanne's lessons are 20minutes long and Jims are 30mins longer than Suzanne's you do: 20+30. Which equals 50minutes. So, Jim's lessons are 50minutes long.
