If x = 4 is the Only Solution of the Equation x² + bx + 16 = 0
Then the Value x = 4 should satisfy the Given Equation
⇒ (4)² + b(4) + 16 = 0
⇒ 16 + 4b + 16 = 0
⇒ 4b + 32 = 0
⇒ 4b = -32
⇒ b = -8
Answer:
mean = 52
Step-by-step explanation:
Just add all four together and divide by 4. That's the mean.

Answer:
Step-by-step explanation:
Measure of the length of an arc of a circle is given as:

It is given that seismic activity d<span>ensity of a region is the ratio of the number of earthquakes during a given time span to the land area affected. so if the there 424 earthquakes and the land area is 71,300 sq miles.
seismic activity density = 424 / 71,300
</span>
<span>seismic activity density = 0.0059
the closest answer in the choices is 0.0056</span>
