Answer:
Actual length of w is 0.075 units.
Step-by-step explanation:
Given the actual length of side t is 0.045 cm.
we have to use the scale drawing to find the actual side length of w.
As given the actual length of t is 0.045 cm.
Hence, we can find the scale factor using the lengths of t i.e actual length and after scale drawing by dividing.
Scale factor is 
Hence, we get the scale factor.
Now, 
⇒ 
⇒ Actual length of w is 
Option B is correct.
Answer:
3.14
Step-by-step explanation:
I dont know if thats correct for sure. I kinda forgot what circumference is.
But how i got this was 6.28/2=3.14
Let me know if this is correct or incorrect.
F(x) = -3x² + 6x - 2
First, we make the coefficient of x² equal to 1
f(x) = -3(x² + 2x - 2/3)
Now, we must make the form a² + 2ab + b²
b = 2x/2x
b = 1
f(x) = -3(x² + 2x + 1² - 1² - 2/3)
f(x) = -3(x² + 2x + 1 - 5/3)
f(x) = -3(x + 1)² - 5
The vertex is (-1 , -5)
And this is the maximum point because the coefficient of the squared term is negative.
Answer:
B
Step-by-step explanation:
First, we have to find the rate of change for this problem. To do this, we subtract any two numbers of days and the coordinating two total questions. Let's just use the first two rows. 8-4=4, and 40-20=20. For every 4 days, he answers 20 questions. We can further simplify this by dividing both sides by 4. 4/4=1, and 20/4=5. For every 1 day, he answers 5 questions. Now, to find 16 days, we just multiply both sides by 16. 16*1=16 and 16*5=80. For every 16 days, he answers 80 questions. 80 is our answer.
Hope this helps!
