How do you solve for the slope of a line with the equation ax^2 + bx + c?
ololo11 [35]
<h2>The graph of y = ax^2 + bx + c </h2><h2>A nonlinear function that can be written on the standard form </h2><h2>ax2+bx+c,where a≠0 </h2><h2>All quadratic functions has a U-shaped graph called a parabola. The parent quadratic function is </h2><h2> y=x2 </h2><h2> The lowest or the highest point on a parabola is called the vertex. The vertex has the x-coordinate </h2><h2>x=−b2a </h2><h2>The y-coordinate of the vertex is the maximum or minimum value of the function. </h2><h2>a > 0                   parabola opens up                    minimum value </h2><h2>a < 0                    parabola opens down              maximum value </h2><h2> A rule of thumb reminds us that when we have a positive symbol before x2 we get a happy expression on the graph and a negative symbol renders a sad expression. </h2><h2>The vertical line that passes through the vertex and divides the parabola in two is called the axis of symmetry. The axis of symmetry has the equation </h2><h2>x=−b2a </h2><h2>The y-intercept of the equation is c. </h2><h2> When you want to graph a quadratic function you begin by making a table of values for some values of your function and then plot those values in a coordinate plane and draw a smooth curve through the points.</h2>

the volume of a pyramid is 84 cubic feet. the area of the base is 21 square feet. find the height of the pyramid
vladimir2022 [97]
Area of the base is 21 square feet
<span>Pyramid Volume = (Area of the Base * Height) ÷ 3
</span>
84 = (21 * Height) / 3Height = 84 * 3 / 21
Height = 12 feet

A stock will have a loss of 11.5% in a bad economy, a return of 2% in a normal economy, and a return of 25.2% in a hot economy.
gladu [14]

Answer:

17.02

Step-by-step explanation:

Calculation for What is the variance of the stock's returns

First step is to calculate the E(R) Expected return

E(R) = .29(−0.115) + .32(0.02) + .39(0.252)

E(R) = .0713*100

E(R)=7.13%

Now let calculate the variance

σ2 = .29(−0.115 −0.0713.)^2 + 32(0.02−0.0713 )^2 + .39(0.252 −0.0713 )^2

σ2 = .1702*100

σ2=17.02%

Therefore the variance of the stock's returns will be 17.02%

Two cyclists, 55 miles apart, start riding toward each other at the same time. One cycles 5 miles per hour faster than the other
tangare [24]

Answer:

r = 6 mph and f = 11 mph

Step-by-step explanation:

Representations:  

1) speed of faster cyclist:  f = r + 5

2) speed of slower cyclist:  r

Distances covered:

(r + 5)(5 hr) + r(5) = 55 mi (total distance covered)

Then 5r + 25 + 5r = 55, or, after reducing this equation:

r + 5 + r = 11, or

2r = 6

Then r = 6 mph and f = 11 mph
