The Red Shell's flight path is modeled by the equation:
y = -2x2 + 60x + 350
a) Factor the equation below:
olutions to the equation?
Answer:
Geometric figure: Straight Line
Slope = 120.000/2.000 = 60.000
x-intercept = 346/-60 = 173/-30 = -5.76667
y-intercept = 346/1 = 346.00000
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
y-(-4+60*x+350)=0

Equation of a Straight Line
1.1 Solve y-60x-346 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-60x-346 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 346/1 so this line "cuts" the y axis at y=346.00000
y-intercept = 346/1 = 346.00000
Calculate the X-Intercept :
When y = 0 the value of x is 173/-30 Our line therefore "cuts" the x axis at x=-5.76667
x-intercept = 346/-60 = 173/-30 = -5.76667
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 346.000 and for x=2.000, the value of y is 466.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 466.000 - 346.000 = 120.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 120.000/2.000 = 60.000
Geometric figure: Straight Line
Slope = 120.000/2.000 = 60.000
x-intercept = 346/-60 = 173/-30 = -5.76667
y-intercept = 346/1 = 346.00000

A triangle has an area of 35 cm squared. The BASE of the triangle is (x-5) cm and the HEIGHT of the triangle is (x-14) cm. Find the measure of the HEIGHT and BASE.
Try to use this method and see if you get the answer
Step-by-step explanation:
area = b * h / 2 , where b is a base, h - height.
so h = 2 * area / b.

a cylinder has an approimate 1357.1 cubic yards. the raduis of the cylinder is 6 yards. what is the height of the cylinder
Answer:
Step-by-step explanation:
Find the radius and height. ...
Convert inches to yards, convert feet to yards, or convert meters to yards.
Multiply the radius of the cylinder times the radius, e.g. r2
Multiply times π to get the area of the circle.
Multiply times the height of the cylinder to get the volume.
please help, i did 90 - 10 and I got 80. I’m stuck at 80
Answer:
approx 216
Step-by-step explanation:
well we go to the 10mm mark and we add the columns taht appear before that. Those are two columns : the brown/orangey one and the green one.
if the scale goes up in twenty and each jump has four squares then we can say that one square is equal to 5 up
so we now can read the first two columns
the first one reads 135
the second one reads approximately 81
we add those up and that becomes 216
so the answer is approximately 216

Please help me with this coordinate geometry homework !!!!
Answer:
Step-by-step explanation:
a. Gradient of A = 7/-7 = -1.
b. For line B, m = 3/1.5 = 2 and c = y-intercept = 3.
c. The line parallel to B will have the same gradient m = 2.
It also passes through (1, -1) so we use the point-slope form of the straight line
y - y1 = m(x - x1)
Here m = 2 and (x1, y1) = (1, -1) so
y - (-1) = 2(x - 1)
y = 2x - 2 - 1
y = 2x -3.
These points are linear.
Find the slope.
x -2 -1 0 1 2

The area in square feet of a rectangular field is
x2 – 120x + 3500. The width, in feet, is x-50. What is the
length, in feet?
Answer:
Length in feet: x-70
Step-by-step explanation:
Use factorization to find the length
Area = X^2-120x+3500
Area= length x width.
Area= L x (x-50)= (x-___) (x-50)
To find L we know that in factoring the quadratic equation 50 x __ must be equal to 3500.
(x-70)(x-50) = x^2-120x+3500.

The smaller of the two containers has a capacity of 150 gallons. When it is $\frac{4}{5}$ full, its contents are emptied into a larger container, filling exactly $\frac{2}{3}$ of it. What is the capacity, in gallons of the larger container?
Answer:
180 gallons
Step-by-step explanation:
The smaller container has 150 gallons.
Now the large container is filled with the 4/5 of the smaller container.
So if the full volume of the small container is 150 gallons so the 4/5 of it can be calculated as, 4/5*150=120 gallons.

MATHEMATICAL CONNECTIONS The volume of a cylinder is given by V=pi r^2h, where r is the radius of the base of the cylinder and h is the height of the cylinder. Find the dimensions of the cylinder. the radius is h-3 and the volume is 25h*pi
[tex]\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=h-3\\ V=25h\pi \end{cases}\implies 25h\pi =\pi (h-3)^2 h \\\\\\ \cfrac{25h\pi }{\pi h }=(h-3)(h-3)h\implies 25=\stackrel{F~O~I~L}{h^2-6h+9}\implies 0=h^2-6h-16 \\\\\\ 0=(h-8)(h+2)\implies \blacktriangleright h= \begin{cases} 8~~\checkmark\\ -2 \end{cases} \blacktriangleleft ~\hfill \blacktriangleright \underset{radius}{\stackrel{8~~ - ~~3}{5}} \blacktriangleleft[/tex]
notice, we didn't use h = -2, because the height cannot be a negative value.
