Fine the length BC using the cosine law. Google the law and sub it in
Answer:
The y-intercept for this equation is 22.
Step-by-step explanation:
You can solve this quite easily by assigning a zero value to x and solving for y. That is where the curve will intersect the x-axis:
y = 2(x - 3)² + 4
y = 2(x² - 6x + 9) + 4
y = 2x² - 12x + 18 + 4
y = 2x² - 12x + 22
<em>EDIT</em>
<em>Note that the expression above is in standard form, though it can also be factored if needed:</em>
<em>y = 2(x² - 6x + 11)</em>
Now we can solve for an x value of zero:
y = 2(0)² - 12(0) + 22
y = 22
So the y-intercept is 22.
Since we are finding total distance, we can just add both together.
5 + 2 = 7ft total traveled
Best of Luck!
Answer:
Your answer is D. x>4
Step-by-step explanation:
Reason:
If you rearrange you'll get
x+8>12
Collect like terms: x>12-8
Therefore you get : x>4
Answer:
30.16 inch is the diameter of the circle
Step-by-step explanation:
circumference = pie X diameter
94.2= 3.14 X d
d = 94.7/3.14
d = 30.16 in
