Answer:

(3,-2)

Step-by-step explanation:

Given equations of line

3x-2y=13

2y+x+1=0​

=> x = -1 -2y

Point of intersection will coordinates where both equation have same value of (x,y)

top get that we have to solve the both equations by using method of substitution of simultaneous equation.

using this value of x in 3x-2y=13, we have

3(-1-2y) -2y = 13

=> -3 -6y-2y = 13

=> -8y = 13+3 = 16

=> y = 16/-8 = -2

x = -1 - 2y = -1 -2(-2) = -1+4= 3

Thus, point of intersection of line is (3,-2)

The side of the base of a square pyramid is increasing at a rate of 666 meters per minute and the height of the pyramid is decre
Otrada [13]

Answer:

105m^3/min

Step-by-step explanation:

We are given that

Base side of square pyramid, a=3 m

Height of square pyramid, h=9m

\frac{da}{dt}=6m/min

\frac{dh}{dt}=-1/min

We have to find  the rate of change of the volume of the pyramid at that instant.

Volume of square pyramid, V=\frac{1}{3}a^2h

Differentiate w.r.t t

\frac{dV}{dt}=\frac{1}{3}(2ah\frac{da}{dt}+a^2\frac{dh}{dt})

Substitute the values

\frac{dV}{dt}=\frac{1}{3}(2(3)(9)(6)+(3^2)(-1)

\frac{dV}{dt}=105m^3/min

Hence, the rate of change of the volume of the pyramid at that instant=105m^3/min

Please help me y’all!!!!
DerKrebs [107]

Step-by-step explanation:

a^2 + 2(b - 6) - 17. a = -7 b = 2

= (-7)^2 - 2(2 - 6) - 17

= 49 - 4 + 12 - 17

= 40
