Answer:

x=2, y=-1

Step-by-step explanation:

$(x+7)+(-y-2)i=9-i$

the (x+7) part corresponds to the 9 and the (-y-2) corresponds to the coefficien of i.

$x+7=9$

Komok [63]

Answer:

Cost, C = $28410.72

Step-by-step explanation:

We have, a concrete pillar has the shape of a cylinder.

Diameter of pillar is 8 m and ts height is 9 m

If concrete costs $87 per cubic meter, it is required to find the concrete cost for the pillar. For this lets find the area of cylindrical shape. So,

$A=2\pi rh+2\pi r^2\\\\A=2\times 3.14\times 4\times 9+2\times 3.14\times 4^2\\\\A=326.56\ m^2$

The cost of pillar at the rate of $87 per cubic meter will be :

$C=326.56\times 87\\\\C=\$28410.72$

How to evaluate this f (x) = -x^+1 for x =-3

sukhopar [10]

Just plug in -3 for x. So it will be -(-3)^+ 1
Which is 3^+1.
I'm confused by your ^ sign I'm not sure if this is supposed to be squared or not...? But just solve/simplify the equation.
Hope this helps!
