Slav-nsk [51]

1) Answer: -\frac{3}{2}

<u>Step-by-step explanation:</u>

f(x) = 6x⁻¹

f'(x) = -6x⁻²

     = \frac{-6}{x^{2}}

f'(-2) = \frac{-6}{(-2)^{2}}

        = -\frac{6}{4}

        = -\frac{3}{2}

*****************************************************

2) Answer: \frac{1}{4}

<u>Step-by-step explanation:</u>

f(x) = -9x⁻¹

f'(x) = 9x⁻²

     = \frac{9}{x^{2}}

f'(6) = \frac{9}{(6)^{2}}

        = \frac{9}{36}

        = \frac{1}{4}

Does anyone know how to crack this code?
seraphim [82]
Area of triangle= (base*hieght)/2
T=(5*6)/2=15
T=15
To the right of T = (4*8)/2 = 16 
Triangle to the right of T=16
Y=(6*6)/2 = 18
Y=18
A=(5*7)/2 = 17.5
A=17.5
To the right of A = (7*7)/2 = 24.5
A=24.5
E = (6.4*8.5)/2 = 27.2
E = 27.2
I = (2.7*3.6)/2 = 4.86
I = 4.86
N = I cant read N
D = (19*17)/2 = 161.5
D = 161.5
Do you think you can complete the rest?

If p varies inversely as q and p =8 when q=10,find p when q=4
Akimi4 [234]

Answer:

20

Step-by-step explanation:

When two numbers vary inversely, they always multiply to the same product, in this case, it is 80, because it is 8 x 10(product of two known values of p and q). This means, for q = 4, we can write:

p * 4 = 80

This means that p is equal to 20.
