Fully factorise 15ab - 35a

Mathematics
1 answer:
sukhopar [10]3 years ago
3 0
The answer is 5a (3b-7).
Step 1: find the common factor. since both 15ab and 35a has a common "a" and a factor of "5", you factorise them out.
Step 2: place the common factor at the front and divide the equation from the common factor.
5a (3b-7) = 15ab - 35a

What is the equation of the line that has a slope of -1 and goes through point (0, 5)?
Leni [432]
To answer the question above, know that one of the way of writing the equation of the line is through the point - slope form which is generally expressed as,
 
                                       y - y1 = m(x - x1) 

where m is the slope and x1 and y1 are the abscissa and ordinate of the point, respectively.

Substituting the given data to the equation above,
 
                                      y - 5 = -1(x -0)

By simplification we get an answer of

                                        y = -x + 5

Find the lateral and surface area of each cone
Sophie [7]

Answer:

\large\boxed{L.A.=153\pi\ mm^2}\\\boxed{S.A.234\pi\ mm^2}

Step-by-step explanation:

The formula of a lateral area of a cone:

L.A.=\pi rl

r - radius

l - slant height

The formula of a surface area of a cone:

S.A.=\pi r^2+\pi rl

We have r= 9mm and l = 17mm. Substitute:

L.A.=\pi(9)(17)=153\pi\ mm^2

S.A.=\pi(9^2)+153\pi=81\pi+153\pi=234\pi\ mm^2

What is the maxima minima or zero for this graph???
ANTONII [103]

Maximum is the highest a graph can reach. In this case the graph continues forever therefore the maximum is:

infinity or ∞

The minimum is the lowest place the graph reaches. In this case it would be:

-6

The zeros are where the graph intersects the x axis. In this case it would have two zeros, which are:

(-3, 0) and (0.5, 0)

Hope this helped!
