Answer:
z =0.001
Step-by-step explanation:
log z + 12 = 9
Subtract 12 from each side
log z + 12-12 = 9-12
log z = -3
Raise each side to the base of 10
10^ log z = 10 ^-3
z = 10 ^-3
z =0.001
Answer: False, True, False, True, True, True
Step-by-step explanation:
Points A, B, and C are coplanar since they're on the same plane but not on the same line.
Both BD and DE intersect since they both have a common point which is D.
The line BD connects both planes.

Answer:
1,512
Step-by-step explanation:
36x42
To solve this problem you must apply the proccedure shown below:
1. You have that the the <span>archway is modeled by the equation y=-2x^2+8x and the angle mentioned in the problem is defined by the equation x−2.23y+10.34=0.
</span>
2. Therefore, you must susbtitute y=-2x^2+8x into x−2.23y+10.34=0, as below:
x−2.23(-2x^2+8x)+10.34=0
3. When you apply the distributive property, you obtain:
x−2.23(-2x^2+8x)+10.34=0
x+4.46x^2-17.84x+10.34=0
4.46x^2-16.84x+10.34=0
4. When you solve the quadratic equation, you obtain:
x=3 units
Therefore, the answer is the option D: D. 3 units.
