6. What are the zeroes for the<br>function<br>f(x) = 2x3 + 12x – 10x2?<br>

agasfer [191]

Answer:

Step-by-step explanation:

f(x) = 2x^3 + 12x – 10x^2 can and should be rewritten in descending powers of x:

f(x) = 2x^3 – 10x^2 + 12x

This, in turn, can be factored into f(x) = x·(x² - 10x + 12).

Setting this last result = to 0 results in f(x) = x·(x² - 10x + 12).

Thus, x = 0 is one root. Two more roots come from x² - 10x + 12 = 0.

Let's "complete the square" to solve this equation.

Rewrite x² - 10x + 12 = 0 as x² - 10x + 12 = 0.

a) Identify the coefficient of the x term. It is -10.

b) take half of this result: -5

c) square this last result: (-5)² = 25.

d) Add this 25 to both sides of x² - 10x + 12 = 0:

x² - 10x + 25 + 12 = 0 + 25

e) rewrite x² - 10x + 25 as the square of a binomial:

(x - 5)² = 13

f) taking the sqrt of both sides: x - 5 = ±√13

g) write out the zeros: x = 5 + √13 and x = 5 - √13.

The three roots are x = 0, x = 5 + √13 and x = 5 - √13.

Help down below pleaseee. I'll rlly give brainliest whoever gives me the best answer if it allows me too since I need at least 2

kodGreya [7K]

Answer:14 dollars, 2 pounds

Step-by-step explanation:

for they first one your just rounding wich is kinda easy you just round it up to the nearest dollar wich is 1 plus 13= 14 dollars.

for the second one it would be better to specify, but since we already did rounding on the first one this might be about the same topic, meaning it might be 2 pounds. But if not 2 and 1/4 of a pound.

Find the area of the region bounded by the y-axis, x-axis and the line y=−2x+4. You have 2 attempts left to earn the full credit

My name is Ann [436]

Answer:

Area of the bounded region = 4 sq units

Step-by-step explanation:

The region bounded by y-axis,x-axis and the given line is in the shape of a right-angled triangle which is right-angled at origin.

Hence :

Area of the bounded region = Area of the right-triangle formed

= $\frac{1}{2}\times base\times height$

Base length of the Δ = x-intercept of the line

Height of the Δ = y-intercept of the line.

x-intercept is obtained by putting y=0 in the equation y=-2x+4

∴x-intercept = 2

y-intercept is obtained by putting x=0 in the equation y=-2x+4

∴y-intercept = 4

Area of the right-triangle = $\frac{1}{2}\times x-intercept\times y-intercept = \frac{1}{2}\times2\times4=4\ sq\ units$
