It’s should be B. The graphs will be identical in shape but the second one will be shifted up 7 units
Answer:
(3)(x+7)(x-1)
Step-by-step explanation:
3x^2+18x-21
Let's start by taking 3 out of the equation.
3(x^2+6x-7)
Now, when we factor, we need to find two numbers that add up to 6 and multiply to -7.
The numbers would be 7 and -1.
So the factored form of this would be:
(3)(x+7)(x-1)
1/3 of 120 is 40
1/4 of 120 is 30
therefore, 10 more scouts in the first group elected to go on the trip
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

This is adding two vectors, one magnitude 300 direction east, and one magnitude 100 direction 30 degrees northeast.
For the resulting sum we can use the Law of Cosines or just add up the components. Let's try it both ways.
Components first. In the east direction we have
300 + 100 cos 30° = 300 + 100(√3/2) = 386.60 miles per hour
In the north direction we have
0 + 100 sin 30° = 100 (1/2) = 50 miles per hour
So a total speed of
sqrt{386.6^2 + 50^2} = 389.82 miles per hour
Answer: 389.82
--------
OK let's try the Law of Cosines. We have sides 300 and 100 and included angle 150°.
