The range of y = - 32x ^ 2 + 90x + 3
Given:
The given function is:
[tex]y=-32x^2+90x+3[/tex]
To find:
The range of the given function.
Solution:
We have,
[tex]y=-32x^2+90x+3[/tex]
It is a quadratic function because the highest power of the variable x is 2.
Here, the leading coefficient is -32 which is negative. So, the graph of the given function is a downward parabola.
If a quadratic function is [tex]f(x)=ax^2+bx+c[/tex], then the vertex of the quadratic function is:
[tex]Vertex=\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)[/tex]
In the given function, [tex]a=-32,b=90,c=3[/tex].
[tex]\dfrac{-b}{2a}=\dfrac{-90}{2(-32)}[/tex]
[tex]\dfrac{-b}{2a}=\dfrac{-90}{-64}[/tex]
[tex]\dfrac{-b}{2a}=\dfrac{45}{32}[/tex]
The value of the given function at [tex]x=\dfrac{45}{32}[/tex] is:
[tex]y=-32(\dfrac{45}{32})^2+90(\dfrac{45}{32})+3[/tex]
[tex]y=\dfrac{2121}{32}[/tex]
The vertex of the given downward parabola is [tex]\left(\dfrac{45}{32},\dfrac{2121}{32}\right)[/tex]. It means the maximum value of the function is [tex]y=\dfrac{2121}{32}[/tex]. So,
[tex]Range=\left\{y|y\leq \dfrac{2121}{32}\right\}[/tex]
[tex]Range=\left(-\infty, \dfrac{2121}{32}\right ][/tex]
Therefore, the range of the given function is [tex]\left (-\infty, \dfrac{2121}{32}\right ][/tex].

Suppose you know the perimeter of a rectangle. How can you write
an equation for the area in terms of the length of a side?
Step-by-step explanation:
L+W+L+W=26 so 2L=26–2W and you can find length from the perimeter as L=13−W
LW=42 so L=42/W is the other way to find the length, from the area. Both ways require you to know W, but if you have both pieces of information the two answers for length must be the same 42/W=13−W, and you solve this:
42=13W−W2
W2–13W+42=0
(W−6)(W−7)=0
Either W−6=0 or W−7=0

Linear equation in slope intercept form
Answer:
y = 2x + 24
Step-by-step explanation:
Slope-intercept form equation => y = mx + b
m = slope = change in y / change in x
b = y-intercept
✔️using two pairs of values form the table, (-6, 12) and (-5, 14):
Slope (m) = (14 - 12)/(-5 -(-6))
m = 2/1
m = 2
✔️To find b, substitute (x, y) = (-6, 12) and m = 2 into y = mx + b.
12 = 2(-6) + b
12 = -12 + b
12 + 12 = b
24 = b
b = 24
✔️To write the equation, substitute m = 2 and b = 24 into y = mx + b:
y = 2x + 24
The area in the trapezoid in square units 10 inches, 8 inches, 12 inches.
Answer: 100
Step-by-step explanation:
The formula for the area of a trapezoid is (B1+B2)/2*h
so substitute:
(8+12)/2*10
20/2*10
10*10
100
Answer:
100 sq inches
Step-by-step explanation:
Simply use the formula for finding the area:
[tex]\frac{1}{2} * (sum of parallel sides) * height\\= \frac{1}{2} * (8 + 12) * 10\\= \frac{1}{2} * 20 * 10\\= 100 sq. inches[/tex]

Which one is correct?
Answer:
The volume of the prism is other; 5.04 m^3
Step-by-step explanation:
Here, we want to get the volume of the prism
What we have to do here is to calculate the area of the trapezoid base and multiply by the height of the prism
The area of the base is;
A = 1/2(a + b) h
a and b are the parallel sides of the trapezoid which is 80 cm and 2 m
h is the height of the trapezoid which is 1.2 m
80 cm is same as 80/100 = 0.8 m (100 cm = 1 m)
A = 1/2( 0.8 + 2)1.2
A = 1/2 * 2.8 * 1.2 = 1.68 m^2
So we proceed to multiply this with the height of the prism which is 3 m
This will be ;
1.68 m^2 * 3 m = 5.04 m^3

Isaiah collects bags of cans for recycling. After they picnic he collected four bags of cans. How many bags did Isaiah take to the recycling center
Answer:
[tex]x + 4[/tex]
Step-by-step explanation:
The question have missing details.
Because, the question says she collected some cans "after picnic"; This means that she has some cans "before picnic"
So, we assume that she has x bags of can before the picnic.
[tex]After\ Picnic = 4[/tex]
So, the total number of bags collected is:
[tex]Total = Before + After\ Picnic[/tex]
[tex]Total = x + 4[/tex]
If x is 5, then she took 9 bags of can to the recycling center
If x is 2, then she took 6 bags of can to the recycling center
If x is 0, then she took 4 bags of can to the recycling center

If the crayon is 90 millimeters long, how
many cubic centimeters of wax is used to
make a box of 8 crayons?
Answer:
373248 cm³ of wax
Step-by-step explanation:
If the crayon is 90 millimeters long, how many cubic centimeters of wax is used to make a box of 8 crayons?
1 crayon = 90mm
8 crayons = x
Cross Multiply
x = 8 × 90mm
x = 720mm
Converting to cubic mm
= (720mm)³ = 373248000mm³
Converting to cubic centimeter
1 mm³ = 0.001 cm³
373248000 mm³ = x
Cross Multiply
373248000 × 0.001 cm³
= 373248 cm³ of wax

The probability of choosing a blue marble from a bag is 5/12 and a yellow marble 1/3. What is the probability of not choosing one of these marbles?
Answer:
1/20
Step-by-step explanation:
Simple probability is found by counting all the results which fit requirements and dividing by all possible results.
To find probability of two results in a row, multiply chance of first result by chance of second result.
Since you are replacing the marble before the second draw, we don’t have to figure out the various changes in odds for the different possible first draws. It’s just that simple.
There are 5 black marbles
There are 4 red marbles
There are always 20 marbles in all
5/20*4/20=1/4*1/5=1/20
By coincidence, the same as the chance of drawing the white marble in one draw.
I AM BEGGING YALL, PLEASE HELP ME OUT
Answer:
(2a,2b)
(-4a,b)
Step-by-step explanation:
for the first one
the x value of coordinate L is going to be twice the value of the x coordinate of k (a)
That being said the x value of L = 2a
The y value of L is going to be half the value of the y value of coordinate A ( 4b )
4b/2=2b so the y value of coordinate L is 2b
now we put the values as an ordered pair
The answer would be (2a,2b)
