Description
Step-by-step explanation:
1. Factor 2x^2+11x+12 -> (2x+3)(x+4)
x=-4, -3/2
Both numbers are rational numbers as both can be expressed in the form in a quotient with integer values.
2. If discriminant is negative, then solutions are imaginary, meaning that the discriminant is less than 0, so you can set up this equation.
11^2 - 4(a)(12) < 0
121 - 48a < 0
a>121/48
The closest integer to 121/48 (~2.52) such that it satisfies the above conditions is 3, so the lowest value for a is 3.

A rectangular prism has a volume of 80 cubic feet. The length of the prism is 8 feet and the height of prism is 4 feet. What is the width of the prism?
Answers
Answer:
2.5
Step-by-step explanation:
8 times 4 is 32, and 80/32 is 2.5. When you have to find another measurement and you know 2 of them, you just have to divide the total of the 2 measurements with the volume. it would be 2.5 feet as the height.
The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $7500 to rent trucks plus an additional fee of $150.25 for each ton of sugar. The second company charges $7143 to rent trucks plus an additional fee of $175.75 for each ton of sugar.
Answers
Answer:
14 tons of sugar
$9603.5
Step-by-step explanation:
For what amount of sugar do the two companies charge the same?
What is the cost when the two companies charge the same?
Let
x = ton of sugar
Company A:
7500 + 150.25x
Company B:
7143 + 175.75x
1. Equate company A and company B
7500 + 150.25x = 7143 + 175.75x
7500 - 7143 = 175.75x - 150.25x
357 = 25.50x
x = 357/25.50
x = 14 tons of sugar
2. Cost when both companies charge the same
Company B:
7143 + 175.75x
= 7143 + 175.75(14)
= 7143 + 2460.5
= 9603.5
Company B = $9603.5
Company A:
7500 + 150.25x
= 7500 + 150.25(14)
= 7500 + 2103.5
= 9603.5
Company A = $9603.5

A farmer grows x acres of peas and y acres of tomatoes. He has 12 acres available to plant peas and tomatoes. Write an inequality in x and y to satisfy this condition. The number acres of tomatoes planted must not be more then twice the number of acres of peas planted. Write an inequality in x and y to satisfy this condition.
Answers
Answer:
Y < 2X
Step-by-step explanation:
Let the acres of land on which pea is to be cultivated is "X" acres and the acres of land on which tomato is to be cultivated is "Y"
It is given that number acres of tomatoes planted must not be more then twice the number of acres of peas planted
Thus, [tex]Y < 2X[/tex]
[tex]X + Y = 12[/tex] acres
[tex]Y = 12-X[/tex] acres
Thus,
[tex]12 - X \leq X\\12\leq 2X\\6 \leq X[/tex]
Let us take X = 6 , Then Y = 13-6 = 6

Graph this: y = 2sIn(x) - 3
Insert picture of graph
Answers
Answer:
We have the function:
f(x) = 2*sin(x) - 3
To graph this type of functions is useful to understand the parts of the function.
A general one is written as:
g(x) = A*sin(w*x + p) + M
where:
A is the amplitude
w is the angular frequency.
p is the phase
M is the midline.
Then in this case we have an amplitude of 2, an angular frequency of 1, a phase of 0 radians and the midline y = -3
Now we can evaluate the function in different points and (knowing how a sine function behaves) connect them, the graph will look something like this:

Answers
Answer:
m<1 = m<2 = 98
Step-by-step explanation:
the measurement of angle 1 and 2 are the same because the two triangle half's (top and bottom) of the polygon are congruent.
any 4 sided polygon has sums of their internal angles = 360 degrees.
(for example a square has four 90 degrees angles, 360=90+90+90+90)
we know that 2 angles are 90 and 74,
we also know that the 2 other angles (m<1 and m<2) are the same,
m<1 +m<2 +90 +74=360
m<1+m<2=360-90-74
2*m<1=196
m<1=196/2
m<1=98
m<2=98
11) Help pls I have the answer I just need to show the work.
True or False. To find the missing side length in the diagram, use the Pythagorean Theorem.
Answer: A
Answers
The Pythagorean theorem is a^2 + b^2 = c^2 where a^2 and b^2 are the two legs of the triangle (two sides connected by the right angle) and c is the hypotenuse (longest side, opposite the right angle).
To solve using the Pythagorean theorem, plug in sides AC and CB into a and b, then solve for c.
23^2 + 31^2 = c^2
529 + 961 = c^2
c^2 = 1490
c = √1490 = 38.601

Find x and y in the given figure
Answers
Answer:
x= 70°, y=40°
Step-by-step explanation:
2x=140
x= 70
y= 180-140= 40
140 + y = 180
y = 180 - 140
y = 40
2x + 40 = 180 (Angle Sum Property)
2x = 180 - 40
2x = 140
x = 140/2
x = 70
X = 70

Complementary angles are two angles whose
measures add to 90°. The ratio of the measures of
two complementary angles is 7:11. What are the
measures of the angles?
Answers
Answer:
let the two complementary angles be x and 90-x
x= 7t (say)
90-x= 11t
x+90-x=90= 7t+11t=18t
90=18t
t=90/18= 10/2= 5
so x= 7×5=35 degrees
and 90-×=90-35=55 degrees
