Find slope intercept form.
(M=1/2) (6,3)

Answers

Answer:

y = (1/2)x

Step-by-step explanation:

Start with that form:  y = mx + b.  Substitute 1/2 for m, 6 for x and 3 for y, for the purpose of finding the value of the y-intercept, b:

3 = (1/2)(6) + b.  Thus, b = 0 and the desired equation is  y = (1/2)x.

Given that,
To find the multiplier for 21.6% decay

What is percentages?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

What is simplification?

The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.

In the question, the multiplier for the rate of 21.6% decay is to be determined.
A multiplier of decay implies decay  = 1 - r

Since let the Decay multiplier be x
x = 1 - r
x = 1 - 0.216
x = 0.784
x = 78.4%

Thus, the required multiplier for 21.6% decay is 78.4%.

The height and the slant height of a cone are 24 cm and 25 cm respectively. Find the volume of the cone.

Pls answer with steps :)

Answers

Answer:

volume =183.26 cm³

Step-by-step explanation:

volume of a cone = 1/3πrl

l is the slant height

using; l²=h²+r²

r²= l²-h²

r²= 25²-24²= 625-576 =49

r=√49=7cm

volume = 1/3πrl = 1/3 (π×7×25)= 1/3 ×549.78

=183.26 cm³

Determine which function has a greater change of rate.
Be sure to show work as well.

Answers

Answer:

A

Step-by-step explanation:

You need to find the slope in A.  y = x + (4x - 1) = 5x -1.   The slope is 5.

In B,  as x increases 1 unit, y increases 1 unit.  Therefore, the rate of change is 1/1 = 1

Conclusion:  In A the rate of change is 5 and in B the rate of change is 1.

Therefore, A has a greater rate of change

four tanks each had 54 litres and 750ml. what is their total capacity in litres ​

Answers

The x-coordinate of one of the endpoints of the dilated segment should be 8.

Calculation of x-coordinate:In the case when a coordinate point (x, y) should be dilated by a factor k, so the coordinate should be (kx, ky).Since the coordinate (4,1), so if this coordinate is dilated by a factor of 2 so the new coordinate points should be at (2(4), 2(1))
