The customer can purchase 1.19788 pounds of cheese (approximately 1.2 pounds).
How much cheese can she purchase?We are given with the cost of ham is $2.49 per pound and
Cost of swiss cheese is $3.79 per pound.
So, the cost of 2 pounds of ham will be given as-
= 2× $2.49
= $4.98
Since, the customer has a total of $9.50 to spend on 2 pounds of ham and some cheese,
∴ Let the number of pounds of cheese she can purchase be x.
Then the equation will be this:
2.49*2 + 3.79*x = 9.50
4.98 + 3.79x = 9.50
Subtracting 4.98 from each side we get-
4.98 -4.98 + 3.79x = 9.50-4.98
3.79x = 4.54
x [tex]=\frac{4.54}{3.79}[/tex]
x = 1.19788 pounds of cheese (approximately 1.2 pounds).
Hence, the customer can purchase 1.19788 pounds of cheese (approximately 1.2 pounds).

Janell is standing on a set of bleacher and throws a ball in the air at an initial velocity of 35 ft/s. The height of the ball, h, at t seconds is modeled by the equation h=-16t^2+35t+6. How many seconds will it take the ball to reach the ground?
The time taken by the ball to reach the ground is 0.067 seconds
Given,
The initial velocity of the ball (speed) = 35 feet/second
The height of the ball (distance), h = -16t² + 35t + 6
We have to find the time, (t in seconds) taken by the ball to reach the ground.
Speed = distance/time
So, Time = distance/speed
Here,
Time = (-16t² + 35t + 6) / 35
We have to solve the equation first.
-16t² + 35t + 6 = 0 is in quadratic form. So, we can solve this by using quadratic formula.
Quadratic formula = [tex]\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}[/tex]
Here,
a = -16, b = 35, c = 6
Now,
[tex]\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}[/tex]
= [tex]\frac{-35(+-)\sqrt{35^{2}-4(-16)(6) } }{2(-16)}[/tex]
= [tex]\frac{-35(+-)\sqrt{1225 +384} }{-32}[/tex]
= (-35±√1609) / -32
= (-35±40.11) / -32
Now,
Solve for:
(-35 + 40.11) / -32 = 5.11/-32 = -0.15
Solve for
(-35 - 40.11) / -32 = -75.11 / -32 = 2.35
Lets take the height as 2.35 feet.
Now,
Time = distance/speed
Time = 2.35/35 = 0.067
Therefore, the time taken by the ball to reach the ground is 0.067 seconds.

Coplanar lines are referred to as parallel lines because they may be extended indefinitely without ever intersecting. || is the sign meaning "parallel to." If two lines are drawn, they don't have to be parallel, and a third line runs across them as seen in the diagram below. We may obtain eight distinct angles by drawing two parallel lines, and then drawing a transverse line through them.
Four pairs of matching angles will be created from all eight angles. One of the pairings is represented by angles F and B in the preceding diagram. If the two lines are parallel, corresponding angles are congruent.

For each ordered pair, determine whether it is a solution to 5x + 2y = -1. (x, y) (1, − 3) (2,8) (-4, -6) (-3,7) what is the soulsion
The following ordered pairs are the solutions to 5x+2y=-1 :
(1,-3) and (-3,7)
Given we have the ordered pairs and the equation.
To find out whether the ordered pair is a solution or not, we just need to replace the x and y values from the ordered pair (x,y) and check if both the sides equate.
a. (1,-3)
5x+2y=-1
5(1)+2(-3) = -1
consider L.H.S
5-6
= -1
Therefore, L.H.S = R.H.S
hence the ordered pair (1,-3) is a solution to 5x+2y=-1.
b. (2,8)
5x+2y=-1
5(2)+2(8) = -1
consider L.H.S
10+16
= 16
Therefore, L.H.S ≠ R.H.S
hence the ordered pair (2,8) is not a solution to 5x+2y=-1.
c. (-4,-6)
5x+2y=-1
5(-4)+2(-6) = -1
consider L.H.S
-20-12
= -32
Therefore, L.H.S ≠ R.H.S
hence the ordered pair (-4,-6) is not a solution to 5x+2y=-1.
d. (-3,7)
5x+2y=-1
5(-3)+2(7) = -1
consider L.H.S
-15+14
= -1
Therefore, L.H.S = R.H.S
hence the ordered pair (2,8) is a solution to 5x+2y=-1.
Therefore the ordered pairs which are solutions to 5x+2y=-1 are:
(1,-3) and (-3,7)

What is an equation of the line that passes through the point (-4,8)(−4,8) and is parallel to the line x+y=6x+y=6?
The equation of the line that passes through the point; (-4, 8) and is parallel to x + y = 6 as required in the task content is; x + y = 4.
What is the equation of the line that passes through the given point and is parallel to the given line?It follows that the equation of the line that passes through the given point and is parallel to the given line is to be determined.
By expressing the given linear equation in slope-intercept form; it follows that we have;
x + y = 6
y = -x + 6
Hence, the slope of the equation by comparison with; y = mx + c is; -1.
Therefore, the slope of the required equation is same as the two lines are said to be parallel.
Ultimately, the required equation from point-slope form of an equation is;
( y - 8) = -1 ( x - (-4))
y - 8 = -x - 4
x + y = -4 +8
x + y = 4.

2. Each year a certain amount of money is deposited in an account which pays an
annual interest rate of r so that at the end of each year the balance in the account is
multiplied by a growth factor of x = 1+r. $500 is deposited at the start of the first
year, an additional $200 is deposited at the start of the next year, and $600 at the
start of the following year.
a. Write an expression for the value of the account at the end of three years in
terms of the growth factor x.
b. What is the amount (to the nearest cent) in the account at the end of three
years if the interest rate is 2%?
3. Consider the polynomial function p given by p(x) = 5x³ + 8x²-3x + 1. Evaluate the
function at x = -2.
Answer:
2a. ((500x +200)x +600)x
2b. $1350.68
3. -1
Step-by-step explanation:
2. You want to know the balance in an account at the end of 3 years with deposits at the beginning of successive years being $500, $200, and $600, and with deposits having an annual growth factor of x. You want (a) an expression for the balance in terms of x, and (b) the balance when x=1+2%.
3. You want the value of p(-2) for p(x) = 5x³ +8x² -3x + 1.
2. Account Balancea. Expression$500 is deposited at the beginning of the first year. The problem statement tells us that this has been multiplied by growth factor x by the end of the year, so the balance at that point is 500x.
At the beginning of the second year, $200 is added to the account, and the entire amount is multiplied by the growth factor for the year. That makes the balance at the end of the second year be ...
(500x +200)x
Then $600 is added, and again the account grows by a factor of x. At the end of the third year, the balance is ...
balance = ((500x +200)x +600)x
b. Balance for r=2%The growth factor is given as x = 1 +r. When r = 2%, this becomes x = 1.02. Then the balance at the end of year 3 is ...
((500·1.02 +200)·1.02 +600)·1.02 = 1350.68
The amount in the account at the end of three years is $1350.68.
__
3. Polynomial valueThe value of p(x) = 5x³ +8x² -3x +1 for x=-2 is found by substituting -2 where x is found. Evaluation can be easier by rewriting the polynomial to Horner form:
p(x) = ((5x +8)x -3)x +1
p(-2) = ((5(-2) +8)(-2) -3)(-2) +1 = ((-2)(-2) -3)(-2) +1 = (1)(-2) +1 = -1
The value of the function for x=-2 is -1.
__
Additional comment
You will note that the expression in problem 2 is also written in Horner form. If it were expanded, it would be 500x³ +200x² +600x. Evaluation takes fewer steps when Horner form is used.
