Answers
Answer:
y=3/4x+1/2
Step-by-step explanation:
slope intercept form: y=mx+b
find the slope with y2-y1/x2-x1: (-4-5)/(-6-6)= 3/4
substitute one of the coordinates in the equation with the slope: 5=3/4(6)+b
solve to find b:
b=1/2
substitute in the equation:

Answer: Choice B) -infinity < x < infinity
==========================================================
Explanation:
The parabola goes on forever to the left and to the right. We can plug in any x value without worrying about something as a division by zero error. So any real number will work.
Writing -infinity < x < infinity refers to the entire number line, which is the set of all real numbers.

A large mixing tank initially contains 1000 gallons of water in which 40 pounds of salt have been dissolved. Another brine solution is pumped into the tank at the rate of 5 gallons per minute, and the resulting mixture is pumped out at the same rate. The concentration of the incoming brine solution is 3 pounds of salt per gallon. If img represents the amount of salt in the tank at time t, the correct differential equation for A is:______.
A) dA/dT=3--.005A
B) dA/dT=5--.05A
C) dA/dT=15--.005A
D) dA/dT=3--.05A
E) dA/dT=15+.05A
Answers
Answer:
If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is is dA/dt = 15 - 0.005A
Option C) dA/dt = 15 - 0.005A is the correction Answer
Step-by-step explanation:
Given the data in the question;
If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is?
dA/dt = rate in - rate out
first we determine the rate in and rate out;
rate in = 3pound/gallon × 5gallons/min = 15 pound/min
rate out = A pounds/1000gallons × 5gallons/min = 5Ag/1000pounds/min
= 0.005A pounds/min
so we substitute
dA/dt = rate in - rate out
dA/dt = 15 - 0.005A
Therefore, If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is is dA/dt = 15 - 0.005A
Option C) dA/dt = 15 - 0.005A is the correction Answer

What method would you call this???? (Factor the polynomial 6x^2-x-2)
I got this answer by first breaking the expression into groups [(6x^2+3x)+(-4x-2)] and then I factor out the 3x from the 6x^2+3x which then that becomes 3x(2x+1). Then I factor out -2 from-4x-2 which becomes -2(2x+1) and then so far we have 3x(2x+1)-2(2x+1) and then we factor out the common term 2x+1 and then we have (2x+1)(3x-2) as our answer.

Which rectangular equation represents the parametric equations x =t Superscript one-half and y = 4t?
ANSWER: A
Answers
The rectangular equation that represents the parametric equation [tex]x=t^{\frac{1}{2} }[/tex] and y = 4t is:
[tex]y=4x^2[/tex] for [tex]x\geq0[/tex]
Note the given representations:
[tex]x=t^{\frac{1}{2} }[/tex]
[tex]y=4t[/tex]
Make t the subject of the formula from the expression [tex]x=t^{\frac{1}{2} }[/tex]
[tex]x^2=t^{\frac{1}{2}\times2\\\\x^2=t\\t=x^2[/tex]
Substitute [tex]t=x^2[/tex] into y = 4t
[tex]y=4x^2[/tex]
Therefore, the rectangular equation that represents the parametric equation [tex]x=t^{\frac{1}{2} }[/tex] and y = 4t is:
[tex]y=4x^2[/tex] for [tex]x\geq0[/tex]

this one, you can use long division ! since the faction of apple to all fruit is 6/15, you divide 6 by 15. you would get the decimal 0.4
in order to make that a percentage, you'd just move the decimal two places to the right, then add a % !! so it's 40% !!
