Answer:

y = 3x - 5

Step-by-step explanation:

Let the equation be y = mx + c

Since the equation is parallel to y = 3x + 6, gradients of the two eqns are the same

therefore, m = 3

sub (4, 7):

7 = 3(4) + c

c = -5

therefore, equation of the line is y = 3x - 5

Hey there, again! :D

Since the angle measuring 38 degrees is adjacent to m<1, it will equal 180 degrees.

180-38= 142

m<1= 142 degrees

I hope this helps!

Plz help me. I forgot how to do this XD

This question has to do with making an approximation based on the diagram of the angle. Angle KLM is an obtuse angle meaning it is larger then 90° but is also less than 180°. The only choices that lie within this range are choices B and D. However, it is safe to assume that angle KLM is closer to 180° than to 90° based on the diagram, therefore the answer must be choice B.

I hope this helps.

Answer:

Volume of the tank = 636 ft³

Step-by-step explanation:

Formula for the volume of a cylinder is,

V = πr²h

Where r = radius of the cylinder

h = height of the cylinder

By substituting the values of radius and height of the water tank given in the question,

V = $\pi (4.5)^{2}(10)$

= 202.5π

= 202.5 × (3.14)

= 635.85 ft³

≈ 636 ft³

Therefore, volume of the cylindrical water tank is 636 ft³.
