does the point ( 2, 1 ) satisfy the equation y = 2x?
Answers
Answer:
No.
Step-by-step explanation:
Y=2x goes up twice and to the right once, it passes through the origin, therefore it won't touch or go pass by point (2,1)
Erik transformed the equation y = 2(x − 2)2 + 5 from vertex form to standard form. His steps are shown below. Is Erik's work correct? If not, identify and correct his error.
y = 2(x − 2)2 + 5
y = 2(x2 − 4x + 4) + 5
y = 2x2 − 8x + 8 + 5
y = 2x2 − 8x + 13
answer choices
No. The error is in the second line: the expanded form of (x − 2)2 is x2 − 4.
No. The error is in the third line: the product of 2 and x2 − 4x + 4 is 2x2 − 4x + 4.
No. The error is in the fourth line: the sum of 8 and 5 is 12.
Yes. Erik is correct in his transformation from vertex form to standard form.

Answers
Answer:
Step-by-step explanation:
use the co-terminal idea Scarlett, 990° = 270 °. You can see this just by looking at the picture.
Tan(270 ) = sin(270) / cos(270) = -sin(90) / cos(90) so now we know that Tan(270) is one of the non-existant angles b/c cos(90) = 0 and that would mean that we have some number over 0... and then the universe blows up.. like my calc II professor liked to say :| I think he was being a bit dramatic. :P anyway, you want answers not long boring stories.. :D so Tan(270) DNE ( does not exist )
If we were to look at a graph of Tan , we'd see that at 270° or 3[tex]\pi[/tex]/2 , Tan runs off to infinity. So there isn't a number to represent it. :/ I'm attaching a picture of the graph
notice in the graph, that when tan gets to 3/2, it's running off to infinity ??

I have 0.0254 it and they say approximately to 2 decimal place will I include the 0 after the decimal point
Answers
Yes. You have to include 0.
If we round off this value to 2 decimal places then it is
0.03
Reason: after decimal point or before decimal point if you have to drop some digits and if the digit to be droped are 5 followed by non zero digit then previous digit is increased by 1.
Here, the digits to be droped are 5 and 4 after 0.02 so we increase 2 by 1 that is 3.

Answer:
Horizontal
Step-by-step explanation:
The mathematical definition of slope is very similar to our everyday one. In math, slope is the ratio of the vertical and horizontal changes between two points on a surface or a line. The vertical change between two points is called the rise, and the horizontal change is called the run.

Step 1. (The capture) Capture a sample total counted =958, and them back tagged counted=38,total tagged=56
The idea is to estimate the proportion p = m/N of tagged =102.
Step 2. (The recapture) After everything has settled down, capture a new sample of n fish. Count the number of tagged fish. Suppose that k of them are tagged.
It is reasonable that, k/n would be a good estimante for p = m/N.
Accordingly, for an estimate N of N, se solve the equation m/N= k/n.

You invest $500 in an account that pays 6% interest compounded continuously. How
much will be in the account after 6 years?
Answers
=====================================================
Explanation:
We'll apply this formula
A = P*e^(r*t)
where,
A = account balance after t yearsP = initial deposit, aka principale = special constant roughly equal to 2.718 but it goes on forever without a pattern; it's better to let the calculator handle this value rather than type the decimal digits in.r = annual interest rate in decimal formt = number of yearsIn this case, we have
P = 500r = 0.06t = 6Again we won't type "2.718..." for 'e', and we'll just type it into the calculator as shown below. That way the calculator can handle the digits instead.
So...
A = P*e^(r*t)
A = 500*e^(0.06*6)
A = 716.66470728026
A = 716.66 dollars is the final answer

What is the equation of the line that passes through the point (2,-4) and has a

Answers
Answer:
y = 2x - 8
Step-by-step explanation:
Point(2 , -4) ; slope = 2
Point- slope form:
y - y1 = m(x - x1)
y - [-4] = 2(x - 2)
y + 4 = 2x - 2*2
y + 4 = 2x - 4
y= 2x - 4 - 4
y = 2x - 8
