Find the point on the y-axis that is 7 units from the point
(−7, −4).
(x, y) =
Answers
Answer:
-7,3
Step-by-step explanation:
The point on y - axis has coordinates = (0, -4)
We have a point whose coordinates are - P(-7, -4)
We have to find the point on the y-axis that is 7 units from the point.
What is the formula to find the distance between the two points on Cartesian plane ?The distance between two points -
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
According to the question, we have -
Coordinates of Point : P(-7, -4)
Since the other point is on y - axis, therefore its x - coordinate will be 0.
Let the point on y - axis have coordinates as - (0, k).
Using the formula discussed above -
7 = [tex]\sqrt {\left( {-7- 0} \right)^2 + \left( {-4 - k } \right)^2 }[/tex]
49 = [tex](-7)^{2}[/tex] + [tex](-4-k)^{2}[/tex]
[tex](-4-k)^{2}[/tex] = 0
[tex](k + 4)^{2}[/tex] = 0
Solve the quadratic equation, you will get -
k = -4
Hence, the point on y - axis has coordinates = (0, -4)

A bottle contains 2 liters of water. The bottle leaks 80 milliliters of water every 3 minutes. Will the bottle be empty in an hour
Answers
Answer:
No
Step-by-step explanation:
2 liters = 2,000
80/3 = 26.6
the bottle leaks 26.6 milliliters in a min
26.6*60 = 1596
1596 / 1000 = 1.596 (to convert to liters)
the bottle will leak 1.596 an hour

Step-by-step explanation:
SP=?
L%=15%
CP=$20
WE KNOW,
L= L%/100×CP
L= 15/100×20

This problem is pretty simple. Since we cannot divide this we can change the division sign into a multiplication, but to do this we need to also take the reciprocal of 2/3, which means we flip th number so it becomes 3/2. Now we can simply multiply. (1/4)*(3/2) which should give you 3/8

Answers
Answer:
the answer is "B"
the "a" (as in ax^2) is negative thus the parabola "goes downward"
Step-by-step explanation:
The equation of parabola is,
y = - 1/2x²
What is Parabola?A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line, which is known as the directrix.
We have to given that;
In a parabola,
Vertex = (0, 0)
Since, We know that;
Standard form of equation of parabola is,
y = a (x - h)² + k
Where, (h, k) = (0, 0) = vertex
Hence, We get;
y = a (x - 0)² + 0
y = ax²
Here, A point on parabola is, (2, - 2)
- 2 = a (2)²
a = - 2 / 4
a = - 1/2
Hence, The equation of parabola is,
y = - 1/2x²

Every problem has a solution .Lets solve it .
Here given that
[tex]\\ \sf\longmapsto x=\dfrac{y}{5}[/tex]
Use cross multiplication[tex]\\ \sf\longmapsto y=5x\dots(1)[/tex]
Now
As its a triangle
[tex]\\ \sf\longmapsto 90+x+y=180[/tex]
Put y=5x[tex]\\ \sf\longmapsto 90+x+5x=180[/tex]
[tex]\\ \sf\longmapsto 6x+90=180[/tex]
[tex]\\ \sf\longmapsto 6x=180-90[/tex]
[tex]\\ \sf\longmapsto 6x=90[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{90}{6}[/tex]
[tex]\\ \sf\longmapsto x=15[/tex]
We need not to find y
See the marked angle and x are supplementary angles hence there sum will be 180
[tex]\\ \sf\longmapsto x+15=180[/tex]
[tex]\\ \sf\longmapsto x=180-15[/tex]
[tex]\\ \sf\longmapsto x=165[/tex]
The required angle is 165°.
