When f(x)=5x^2-2x+5, evaluate f(-3)

Mathematics
1 answer:
patriot [66]3 years ago

Answer:

f(-3)=56

Step-by-step explanation:

When evaluating a specific input for a function, you just plug that input in for x.

So in this case, f(-3)=5(-3)^2-2(-3)+5

f(-3)=5(-3)^2-2(-3)+5

f(-3)=5(9)+6+5

f(-3)=45+6+5

f(-3)=56

What is 500 rounded to the nearest hundred
rosijanka [135]

Answer: 500

The reason why it's 500 because it's already been rounded. 500 stays as 500 bc numbers 4 and below goes down to 0 when rounding. When rounding 0-4 with just the ones place it stays the same.

Please help me, I have no idea what the equation for the new path is. <br><br> Thank you!!
Citrus2011 [14]
First, find the slope of the initial line; 

m=(y₁-y₂)/(x₁-x₂) 

m=(4-0)/(11-8) 
m=4/3 

If two lines are parallel, the slope is the same although the intercept can differ. 

If this parallel lines passes through the point (4, 5); 

y=(4/3)x+c <-- plug in coordinates to solve for c
5=(4/3)(4)+c 
(15/3)=16/3+c 
(15/3)-(16/3)=c 
-1/3=c 

Therefore, the final equation should be y=4/3x-1/3

Hope I Helped :)

Insert three arithmetic means between 25 and 9​
Aleonysh [2.5K]

Answer:

21, 17, 13

Step-by-step explanation:

Find the mean of the 2 given values

mean = \frac{25+9}{2} = \frac{34}{2} = 17

Noe find the mean of 25 and 17 and 17 and 9

mean = \frac{25+17}{2} = \frac{42}{2} = 21 and

mean = \frac{17+9}{2} = \frac{26}{2} = 13

Thus the 3 means are 21, 17 and 13, that is

25, 21, 17, 13, 9
