Answer:

D. Sasha's method is exponential because it increases by a fixed factor, and Mona's method is linear because it increases by a fixed number.

Step-by-step explanation:

In Sasha's case, we can see that she is increasing her time by a factor of 2 from the previous week. So, its exponentially growing.

And in Mona's case, we can see that she is increasing her time by 10 minutes. So, it is linear in nature.

So, option D is correct.

Answer:

I will just give you the way of solving it

Step-by-step explanation:

First you have to change the sgape of the equation and it will become like this :

-6y=-2x+12

And then:

Y=0.33x+2

And then you have to give values to x and find y

For example i will make x zero (0)

It will become

Y=0.33(0)+12

=+12

And the points are (0,+12)

Go on like this and draw the line

Good luck

Find an equation of variation in which y varies directly as x and y=420 when x= 100. Then find the value of y when x=11.
sweet [91]
Let's Simplify X to equal 1 by dividing by 100. then we divide 420 by 100 to get 4.2, so y=4.2 when x=1, we then multiply by each by 11.

y = 46.2
x = 11

Marizza181 [45]

Answer:

f(x) = sec x. tan x

⇔ f(x) = 1/cosx . cosx/sinx

⇔ f(x) = sin x

+) when f(x) is increasing => sin x increases

=> x will increase

+) f(x) is decreasing => x will decrease

+) f(x) is concave up => x ∈ (-pi/2; 0)

+) f(x) concave down => x ∈ (0; pi/2)
