A football is kicked at 40 yards away from a goal post that is 10 feet high. Its path is modeled by y = -0.03x^2 + 1.6x, where x is the horizontal distance in yards traveled by the football and y is the corresponding height above the ground in feet.
Does the football go over the goal post? How far above or below the goal post is the football? Use two or more complete sentences to explain your answers. (Hint: The unit conversion is built into the given function.)
Answer:
at goal post x= 35
the height will be y= –0.03x2 + 1.6x= 19.25 > 15
is 4.25 feet above the goal post.

The grades on a chemistry midterm at Springer are roughly symmetric with μ=67\mu = 67μ=67mu, equals, 67 and σ=2.0\sigma = 2.0σ=2.0sigma, equals, 2, point, 0. William scored 66 on the exam. Find the z-score for William's exam grade. Round to two decimal places.
Answer: - 0.50
Step-by-step explanation:
Given the following :
Mean score = 67
Standard deviation = 2
To obtain the Zscore, use the relation:
Zscore = (X - mean) / standard deviation
Williams score = 66 = X
Hence,
Zscore = (66 - 67) / 2
Zscore = - 1 / 2
Zscore = - 0.50

Explain the difference between a two-variable equation graph and a two-variable inequality graph. Give an example of an equation
Answer:
What makes graphing linear inequalities in two variables different from graphing linear equations in two variables?
The graph of linear inequalities include a dashed line if they are greater than or less than but not equal to. Linear equations, on the other hand, include a solid line in every situation. Moreover, linear inequalities include shaded regions whereas linear equations do not.

2. Find the equation of a line parallel to y=6x-4 and through point (-2,14)
Answer: y=6x+26
Step-by-step explanation:
To find the equation of a line parallel to the given equation, the slope must stay the same. Parallel lines NEVER touch or cross. Therefore, the slope MUST be the same. All we have to do is plug the given point into the equation to find the y-intercept.
14=6(-2)+b [multiply]
14=-12+b [add both sides by 12]
b=26
Now, we know that the equation of y=6x+26.
3 10 in . = 7 8 mi . what is the unit rate
Answer: (3/10) in = (7/8) mi
1 in = (7/8) mi ÷ (3/10)
= 7/8 * (10/3) = 70/24
1 in = (70/24) mi
It means every 1 inch on the map drawing represents (70/24) miles ≈ 2.917 miles in reality.

Joshua and his children went into a grocery store and will buy bananas and peaches.
Each banana costs $0.70 and each peach costs $2. Joshua has a total of $25 to spend
on bananas and peaches. Write an inequality that would represent the possible values
for the number of bananas purchased, b, and the number of peaches purchased, p.
Answer:
[tex]0.7b+2p \leq 25[/tex]
Step-by-step explanation:
So, we know that each banana costs $0.70 and each peach costs $2. So, the total when purchasing b bananas and p peaches can be written as the expression:
[tex]0.7b+2p[/tex]
Where b represents the amount of bananas purchases and p represents the amount of peaches purchases.
Joshua has at maximum $25 to spend. The total cannot exceed $25. In other words, the total of the above expression must be less than 25. So, our inequality will be:
[tex]0.7b+2p<25[/tex]
However, it is also possible for Joshua to spend exactly $25. So, we also need an equal sign. Therefore, our final inequality will be:
[tex]0.7b+2p \leq 25[/tex]
In words, this means that the total cost depending on the number of bananas and peaches Joshua buys must be less than or equal to 25.
And we're done!

i don’t really know the second one, but at least there’s the first! i’m sorry
You’re just solving for a variable
Step-by-step explanation:
(ab/4) +bc = 12 -xc
multiply both sides by 4
ab + 4bc = 48 - 4xc
Transfer -4xc to the other side
ab + 4xc + 4 bc = 48
Transfer ab to the other side
4xc + 4bc = 48 - ab
take c as a common factor
c( 4x - 4b) = 48 - ab
divide both sides by ( 4x - 4b)
c ( 4x - 4b)/( 4x - 4b) = (48- ab)/( 4x - 4b)
c = ( 48-ab)/( 4x - 4b)

Two squares with the same side lengths are always congruent.
Side lengths are not used to determine congruence.
OTwo rhombuses with the same side lengths are always congruent.
OTwo parallelograms with the same side lengths are always congruent.
Answer:
A. Two squares with the same side lengths are always congruent.
Step-by-step explanation:
Congruence is a relation that shows similarity between the shape or size of two or more given figures. It can be determined by comparing the size of the angles or sides of the figures involved.
A square has equal length of sides, therefore two squares with the same side lengths are always congruent in all respect (shape and area). The statement in option a is TRUE.
Please answer as soon as possible thank you

Which of the following statements cannot be assumed from the diagram?
Answer:
Option (2)
Step-by-step explanation:
Option (1).
Points A, B and D are collinear.
True. (On plane S)
Option (2).
Points A, B, C and E are coplanar.
False.
(Points A, B and D are on plane S and points C and E are on plane R)
Option (3).
BE intersects line 'n' at point B.
True.
Option (4).
CB ⊥ AD
(CB lies on plane R and AD lies on perpendicular plane S).
Option (5).
Line 'm' ⊥ plane R.
True.
(Line m is on plane S which is perpendicular to plane R).
Option (6).
Plane R intersects plane S at line n.
True.
Plane R and Plane S are perpendicular and the point of intersection is line 'n'.
Therefore, Option (2) is incorrect.

Answer:
h = 3 ft
Step-by-step explanation:
The lateral surface area of a cylinder is given by
LSA=2πrh where r is the radius and h is the height
The diameter is 312 inches
Changing to ft
312/12 =26 ft
Dividing by 2 to get the radius
26/2 = 13 ft
LSA=2πrh
Using 3.14 for pi
245 ft^2 = 2 * 3.14* 13 ft * h
245 = 81.64 h
Divide each side by 81.64
245/81.64 = 81.64 h/81.64
3.000979912 = h
To the nearest foot
3 = h
Answer:
h=3
