We are given that;
Its dealers demand at least 30 skateboards per day and 20 pairs of in-line skates per day. The factory can make at most 60 skateboards and 40 pairs of in-line skates per day. The total number of skateboards and pairs of in-line skates cannot exceed 90. The profit of each skateboard is $12 and the profit on each pair of in-line skates is $19
Thus, the inequalities are as follows;
Let x represent number of skateboards
Let y represent in-line skates
Thus;
x ≥ 30
y ≥ 20
x ≤ 60
y ≤ 40
x + y ≤ 90
y ≤ -x + 90
f(x, y) = 12x + 19y
At (30, 20), f(30, 20) = 12(30) + 19(20) = $740
At (30, 40), f(30, 40) = 12(30) + 19(40) = $1120
At (50, 40), f(50, 40) = 12(50) + 19(40) = $1360
At (60, 20), f(60, 20) = 12(60) + 19(20) = $1100
At (60, 30), f(60,30) = 12(60) + 19(30) = $1290
Thus, the maximum profit the company can make given these constraints is; $1360

f has a range of (-4, infinity), and a graph that is symmetric about the line x = -1 , and has a y- intercept of -3
The graph of the parabola is given at the end of the answer.
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
Considering the range and the symmetry line, the vertex of the function is at (-1,-4) and:
h = -1, k = -4.
Hence:
y = a(x + 1)² - 4.
It has a y-intercept of -3, that is, when x = 0, y = -3, hence we use it to find a as follows.
-3 = a - 4
a = 1.
Hence the function is:
y = (x + 1)² - 4.
The graph of this function is given at the end of the answer.

use the discriminant to find the number of real solutions of the equation
3x 2 -5x +4=0
Answer:
zero real solutions
Step-by-step explanation:
You want the number of real roots of 3x² -5x +4 = 0 and determined by using the discriminant.
DiscriminantThe discriminant of a quadratic equation ax²+bx+c=0 is ...
d = b² -4ac
When d < 0, both roots are complex. When d = 0, there is one (repeated) real root. The number of real solutions is 2 when d > 0.
ApplicationFor this equation, a=3, b=-5, c=4, so the discriminant is ...
d = b² -4ac = (-5)² -4(3)(4) = 25 -48 = -23
This means both roots are complex. There are no real solutions.

As confirmation, we can look at the graph. It does not cross the x-axis, so there are no (real) values of x that make the value of the quadratic be zero.
a bucket holds c liters of water but a jar holds d liters more how much water do they hold together
The bucket and the jar together will hold (c + d) litres of water.
What is defined as linear equation on two variables?A linear function does have a positive relationship, so increasing one variable (input variable) causes a rise in the second variable (output variable), implying that the variables have always been directly proportional. As a result, the graph of such a linear function is a straight line with a constant slope.Correspondingly, a linear equation is a first-order algebraic equation with two variables and terms with exponents of one.A linear equation in 2 variables [x and y] is any equation with the form:
ax + by = c and at least one of a or b being non-zero.
This is known as the equation's General Form.
For the given question;
The water hold by bucket = c litres.
The water hold by jar = d litres.
Thus, the water hold by both bucket and jar is is linear equation with two variable c and d.
Total water = c + d
By, varying any value the total amount of the water will also get change.

For which value of x is line l parallel to line m?
(Click document to see image.)
Answer:
x = 30°
Step-by-step explanation:
If l and m are parallel lines, then corresponding angles should be congruent.
3x - 20 = 2x + 10
Add 20 to both sides,
3x = 2x + 10 + 20
3x = 2x + 30
Subtract 2x from both sides,
3x - 2x = 30
x = 30

If an arrow is shot upward on the moon with a velocity of 58 m/s, its height in meters after t seconds is given by y=58t−.83t2.
(a) Find the average velocity over the given time intervals:
(1) [1,1.5]
(2) [1,1.1]
(3) [1,1.01]
(4) [1,1.001]
(b) Find the instantaneous velocity after one second (to the nearest hundredth).
(1) m/s
(2) m/s
(3) m/s
(4) m/s
(b) m/s
The 58 m/s initial velocity of the arrow with height, y = 58•t - 0.83•t², gives;
(1) 55.925 m/s
(2) 56.257 m/s
(3) 56.3317 m/s
(4) 56.33917 m/s
(b) 56.34 m/s
How can the average and instantaneous velocity be calculated?Initial velocity of the arrow = 58 m/s
Height of the arrow is; y = 58•t - 0.83•t²
The above kinematic equation can be analyzed as follows;
(1) The height at t = 1 is found as follows;
y = 58 × 1 - 0.83 × 1² = 57.17
Height at t = 1.5 s. is y = 58×1.5 - 0.83×1.5² = 85.1325
Average velocity = ∆y/∆tWhich gives;
Average velocity = (85.1325-57.17)/(1.5-1) = 55.925
The average velocity in the interval [1, 1.5] is therefore;
55.925 m/s(2) [1, 1.1]
Height at t = 1.1 s. is y = 58×1.1 - 0.83×1.1² = 62.7957
Which gives;
Average velocity = (62.7957-57.17)/(1.1-1) = 56.257
The average velocity is 56.257 m/s(3) [1, 1.01]
Height at t = 1.01 s. is y = 58×1.01 - 0.83×1.01² = 57.733317
Which gives;
Average velocity = (57.733317-57.17)/(1.01-1) = 56.3317
The average velocity is 56.33 m/s
(4) [1, 1.001]
Height at t = 1.01 s. is y = 58×1.001 - 0.83×1.001² = 57.22633917
Which gives;
Average velocity = (57.22633917-57.17)/(1.001-1) = 56.33917
The average velocity is 56.33917 m/s(b) The equation for the instantaneous velocity is found as follows;
v = dy/dt = 58 - 2×0.83•t
After 1 second, we have;
t = 1
v = 58 - 2×0.83 × 1 = 56.34
The instantaneous velocity at t = 1 seconds is 56.34 m/s

find the measure of the indicated angle that makes lines u and v parallel
To make lines u and v parallel, the indicated angle must be 108°.
What are angles?An angle is a figure in Plane Geometry formed by two rays or lines that share a common endpoint. "Angle" comes from the Latin word "angulus," which means "corner." The two rays are referred to as the sides of an angle, and the common endpoint is referred to as the vertex.So, if two parallel lines n and m intersect, then all the angles generated in line m must be exactly the same as the angles generated in line n.
At the intersection of two lines, two adjacent angles must add up to 180°.According to the first criterion, the missing angle denoted by a "?" must have the same measure as the angle just below the 72° angle.According to the second (and previously used) criterion, we must have:
? + 72° = 180°When we solve that, we get:
? = 180° - 72° = 108°Therefore, to make lines u and v parallel, the indicated angle must be 108°.
