write a quadratic equations given the roots 5/2 and 9
Answer:
(x-5/2)(x-9).
x^2-5/2x-5/2x+45/2.
Multiply the number by 2.
which is 2(x^2-5/2x-5/2x+45/2).
2x^2-5x-5x+45.
2x^2-10x+45.
Which number is a reasonable estimate for 553 +363?
A 1,300
B 1,000
600
D 200
its b because you can round 363 to 400 and 553 to 600 400 + 600 = 1000
Solve for h : -37+h=-2
Answer:
h = 35
Step-by-step explanation:
Step 1: Write out equation
-37 + h = -2
Step 2: Add 37 to both sides
-37 + 37 + h = -2 + 37
h = 35
Is there a known infinite product for e? What I mean is, it’s similar to an infinite series.
"e" is an irrational number because it cannot be seen as a quotient of two integers. In the bright side, it can be shown as a continued fraction. "e" may also be used as an infinite product, infinite series, and any other limit to any sequence.
Best of Luck!

3/6 = 1/2 or 50%Write an equation in slope-intercept form for the line that passes through the point ( 2 , 3 ) and is perpendicular to the line − 5 x + 4 y = − 3 .
The slope of a line in standard equation will be [tex]\frac{-A}{B}[/tex]
[tex]m=\frac{5}{4}[/tex]
The slope of a perpendicular line to this line will be opposite and reciprocal.
[tex]m=-\frac{4}{5}[/tex]
Then, we can plug in the point given to get the [tex]b[/tex] value.

58 POINTS!!! The line contains the point (8,2) and is parallel to a line with a slope of -2/3 The equation of the line is
Answer:
The answer is
[tex]y = - \frac{2}{3} x + \frac{22}{3} [/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
Since the lines are parallel their slope are also the same
So the slope of parallel line = - 2/3
So the equation of the line containing the point (8 , 2) and slope - 2/3 is
[tex]y - 2 = - \frac{2}{3} (x - 8) \\ y - 2 = - \frac{ 2}{3} x + \frac{16}{3} \\ y = - \frac{2}{3} x + \frac{16}{3} + 2[/tex]
We have the final answer as
[tex]y = - \frac{2}{3} x + \frac{22}{3} [/tex]Hope this helps you
Slope intercept form: y = mx + b
Parallel lines have the same slope, so the slope is -2/3.
We can solve using point slope form.
y - 2 = -2/3(x - 8)
y - 2 = -2/3x + 16/3
y = -2/3x + 22/3

Since cos(x) is the derivative of sin(x), then integral 16 sin^2(x) cos(x) dx can be done by substituting u = sin (x) sin (x) and du = cos (x) cos (x)^dx. With the substitution u = sin(x), we get integral 16 sin^2 (x) cos(x) dx = 16 integral u^2 du. which integrates to + C. Substituting back in to get the answer in terms of sin(x), we have integral 16 sin^2 (x) cos (x) dx = + C.

Find the integral of [tex]f(x) = 16sin^2 (x ) cos(x) dx[/tex]
Answer:
The solution is [tex]\frac{16}{3} sin^{3}x + c[/tex]
Step-by-step explanation:
So
[tex]Let \ u = sin(x)[/tex]
=> [tex]\frac{du}{dx} = cos (x)[/tex]
=> [tex]du = cos(x)dx[/tex]
So
[tex]\int\limits {16sin^2 (x ) cos(x) dx} \, \equiv \int\limits {16u^2 du}[/tex]
=> [tex]\int\limits {16u^2 du} = 16 [\frac{u^3}{3} ] + c[/tex]
Now substituting sin(x) for u
[tex]\frac{16}{3} u^3 + c = \frac{16}{3} sin^{3}x + c[/tex]
So the integral of [tex]f(x) = 16sin^2 (x ) cos(x) dx[/tex] is
[tex]\frac{16}{3} sin^{3}x + c[/tex]

What is (6x10^6)(4x10^-1) ?
Answer:
Step-by-step explanation:
Multiply the 6 and 4 together. 6*4 = 24
The next part is a bit tricky. Add the powers on the base 10. Keep the base 10.
10^(6 - 1) = 10^5
Now put the two parts together. 24 * 10^5
The number in front of the 10 must be between 1 and 10.
So 24 can be written as 24 = 2.4 * 10^1
2.4 * 10^1 * 10^5 = 2.4 * 10^(5 + 1) = 2.4 * 10^6

p: Two linear functions have different coefficients of x.
q: The graphs of two functions intersect at exactly one point.
Which statement is logically equivalent to q-p?
If two linear functions have different coefficients of x, then the graphs of the two functions intersect at exactly one
point.
O If two linear functions have the same coefficients of x, then the graphs of the two linear functions do not intersect
at exactly one point.
If the graphs of two functions do not intersect at exactly one point, then the two linear functions have the same
coefficients of x.
O If the graphs of two functions intersect at exactly one point, then the two linear functions have the same
coefficients of x.
Answer:
Linear function A and linear function B both have the same input values as shown below. Why will the output values for linear function A always be different than the corresponding output values for linear function B? The initial values of the two functions are different, and the rates of change of the two functions are also different. The initial values of the two functions are different, and the rates of change of the two functions are the same. The initial values of the two functions are the same, and the rates of change of the two functions are different. The initial values of the two functions are the same, and the rates of change of the two functions are also the same.
