Talja [164]3 years ago
5 0

Answer: -4

Step-by-step explanation:

3 times that number→3x

Difference of the square of a number and 28→x^2-28

x^2 −28= 3x

-3x =-3x

x^2-3x-28=0

(x-7)(x+4)=0

x-7=0

x+4=0

x=7  x=-4

{Negative Solution: }-4

Negative Solution: −4

If f is the function defined by f(x) = 3x^5 - 5x^4, what are all the x coordinates of points of inflection for the graph of f?
gregori [183]

Answer:

D: 0 and 1

Step-by-step explanation:

Function is defined by;

f(x) = 3x^(5) - 5x⁴

Now, an inflection point will be a point on the graph where the inflection or concavity changes.

Thus, let's find the derivatives until we get there;

f'(x) = 15x⁴ - 20x³

f''(x) = 60x³ - 60x²

So factorizing gives;

f''(x) = 60x²(x - 1)

At f''(x) = 0, we have; x = 0 or x = 1

Thus, the x coordinates of points of inflection are 0 & 1

The formula of an area of a kite:

A=\dfrac{pq}{2}

p, q - diagonals

We have p = 17 and q = 15.3. Substitute:

A=\dfrac{(17)(15.3)}{2}=\dfrac{260.1}{2}=130.05

Find the value of x.<br> A) 21 <br> B) 27 <br> C) 31 <br> D) 34
Ivahew [28]

The 2 angles given are vertical angles, which mean they are the same.

So we have: 3x +1 = 64


Subtract 1 from each side:

3x = 63

Divide both sides by 3:

X = 63 / 3

X = 21


The answer is A.
