Answer:
C) y = 2x +8
Equation of the straight line passing through the point (-2,4) and having slope m =2
y = 2x +8
Step-by-step explanation:
Step(i):-
Given that the points are (-2,4) and (6,20)
The slope of the line
m = [tex]\frac{20-4}{6-(-2)} = \frac{16}{8} =2[/tex]
m =2
Step(ii):-
Equation of the straight line passing through the point (-2,4) and having slope m =2
y - 4 = 2( x-(-2))
y = 4 + 2x +4
y = 2x +8

If triangle ACD is similar to triangle ABE, find the value of x?
Answers
The value of x and y from the given figure is 2.1 units and 4.5 units.
Given that, triangle ACD is similar to triangle ABE.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
Here, AB=3, AC=5, BE=x, AE=y, ED=3 and CD=3.5
AD=AE+ED
AD=y+3
Now, AB/AC = AE/AD = BE/CD
So, 3/5 = y/(y+3) = x/3.5
⇒ 3/5 = x/3.5
⇒ 3×3.5=5x
⇒ 5x=10.5
⇒ x=10.5
⇒ x=2.1
3/5 = y/(y+3)
⇒3y+9 =5y
⇒2y =9
⇒y =4.5
Therefore, the value of x and y from the given figure is 2.1 units and 4.5 units.

What is the area of a triangle with a base of 7 units and a height of 11 units?
A. 154 sq. units
B. 38.5 sq. units
C. 19.25 sq. units
D. 77 sq. units
Answers
Answer:
B
Step-by-step explanation:
Area of a triangle formula: 1/2bh
1/2*7*11 = 38.5 sq units
The value of area of a triangle with a base of 7 units and a height of 11 units is,
⇒ Area of triangle = 38.5 units²
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Base of triangle = 7 units
Height of triangle = 11 units
We know that'
Area of triangle = 1/2 x Base x Height
Hence, We get;
The value of area of a triangle with a base of 7 units and a height of 11 units is,
⇒ Area of triangle = 1/2 x Base x Height
⇒ Area of triangle = 1/2 x 7 x 11
⇒ Area of triangle = 38.5 units²
Thus, The value of area of a triangle with a base of 7 units and a height of 11 units is,
⇒ Area of triangle = 38.5 units²

Given parallelogram FGHI determine the missing information
Don’t answer with one answer, blank or ridiculous answer please this is serious
Answers
Answer:
y = 3 cm and x = 2.5 cm
Step-by-step explanation:
As we can see it is a parallelogram so
y = 3 cm (being opposite sides of parallelogram)
Now while calculating the diagonal we can use the Pythagoras relation. i.e
perpendicular (p) = 4 cm (IH)
Base (b) = 3 cm (FI)
Hypotenuse (h) = FH = ?
We know by using Pythagoras theorem
h = √ p² + b²
= √ 4² + 3²
= √ 25
= 5 cm
Here we got FH = 5 cm
so the value of x will be 2.5 cm as the diagonal bisects.

Step-by-step explanation:
g Suppose that a large mixing tank initially holds 500 gallons of water in which 50 pounds of salt have been dissolved. Another brine solution is pumped into the tank at a rate of 3 gal/min, and when the solution is well stirred, it is then pumped out at a slower rate of 2 gal/min. If the concentration of the solution entering is 2 lb/gal, determine a differential equation (in lb/min) for the amount of salt A(t) (in lb) in the tank at time t > 0. (Use A for A(t).)
Answers
Answer:
the required differential equation is dA/dt - [tex]\frac{2A}{t+500}[/tex] = 6
A(0) = 50lb
Step-by-step explanation:
Given the data in the question;
A(t) is the mass of the salt in in the tank at time t
the new volume of the solution in the tank increases by one gallon each minute
so
dA/dt = ( Rate in) - ( Rate out)
dA/dt = ( 3 gal/min × 2 lb/gal ) - ( 2 gal/min × [tex]\frac{A}{t+500}[/tex] lb/gal )
dA/dt = 6 - [tex]\frac{2A}{t+500}[/tex]
dA/dt - [tex]\frac{2A}{t+500}[/tex] = 6
A(0) = 50lb
Therefore, the required differential equation is dA/dt - [tex]\frac{2A}{t+500}[/tex] = 6
A(0) = 50lb
