Answer:
x = 7
Step-by-step explanation:
Because:
GD = x + 4
GC = 4x + 5
And D is the centroid of ABC
So GC = 3GD
<=> 4x + 5 = 3(x + 4)
<=> 4x + 5 = 3x + 12
<=> 4x - 3x = -5 + 12
<=> x = 7
Done!!
You ok?? :))
Answer:
44
Step-by-step explanation:
The exponential function is y = 650(1.0475)ˣ
<h3>
Exponential equation</h3>
A Exponential equation is in the form:
y = abˣ
where y, x are variables, b is the multiplier and a is the initial value.
Let y represent the bacteria population after x hours.
a = 650 bacteria
b = 100% + 4.75% = 1.0475
The exponential function is y = 650(1.0475)ˣ
After 33 hours:
y = 650(1.0475)³³ = 3006

Answer:
2 a
Step-by-step explanation:
Possible derivation:
d/dx(2 a x + 2 a y)
Differentiate the sum term by term and factor out constants:
= 2 a (d/dx(x)) + d/dx(2 a y)
The derivative of x is 1:
= d/dx(2 a y) + 1 2 a
The derivative of 2 a y is zero:
= 2 a + 0
Simplify the expression:
Answer: 2 a
