Celina says that each of the following expressions is actually a binomial in disguise:(Expressions in picture) For example, she

Juliette [100K]

Yes , she is right. All the remaining can be expressed in binomial.

II) $5x^3 * 2x^2 - 10x^4 + 3x^5 + 3x * (-2)x^4$

$10x^5 - 10x^4 + 3x^5 + -6x^5= 7x^5 - 10x^4$ is a binomial

iii) $(t+2)^2 - 4t = t^2 + 4t + 4 -4t = t^2 + 4$ is a binomial

iv) $5(a-1) - 10(a-1) + 100 ( a-1) = 5a - 5 - 10a + 10 + 100a -100 = 95a -95$ is a binomial

v) $( 2\pi r -\pi r^2)r - ( 2\pi r -\pi r^2)2r = 2\pi r^2 -\pi r^3 - 4\pi r^2 + 2\pi r^3$ = $-2\pi r^2 + \pi r^3$ is also a binomial

Write the equation of each line in slope-intercept form. (If possible please show work)

Alik [6]

Answer:

y = 5x - 4

Step-by-step explanation:

Step 1: Write known variables

m = 5

y = 5x + b

Step 2: Find b

6 = 5(2) + b

6 = 10 + b

b = -4

Step 3: Rewrite equation

y = 5x - 4

Find the second derivative at the point (1,1), given the function below. 2x^9+1=3y^3

lyudmila [28]

The value at point ( 1, 1 ) is 8.

Explanation:

Given

3y³ = 2x⁹ + 1

y³ = 2/3x⁹ + 1/3

y = ∛2/3 x⁹ + 1/3

We need to first find dy/dx which is the first derivative and then d²y/dx² which is the second derivative

$\frac{dy}{dx} = \frac{2x^8}{y^2}$

$\frac{d^{2}y }{dx^2} = \frac{16x^7}{y^2} - \frac{8x^1^6}{y^5}$

Put the value of (1,1) : x = 1 and y = 1 in d²y/dx² equation

$\frac{d^2y}{dx^2} = \frac{16 X 1^7}{1^2} - \frac{8 X 1^1^6}{1^5}$

$\frac{d^2y}{dx^2} = 16 - 8\\\\\frac{d^2y}{dx^2} = 8$

Therefore, the value is 8.

Please help I’m on the middle of an exam Use the diagram of ABCD to find x.

garri49 [273]

This is like property of a parallelogram you have to do is basically follow its properties which is opposite sides are congruent

so we solve like this

$x+3=2x-5$

subtract -3 on each side one is canceled since its equal to zero

and other is -3-5= -8

$x=3x-8$

now subtract -3 on each side

-3x-x is -4 so,

-4x=8

divide its equal to 2

X=2

Hope it helps! have an awesome day you should probably study the properties of parallelogram
