How do i factor the quadratic expression 4x^2-11x=3

Answers

Answer 1

Answer: 4x² - 11x = 3
4x² - 11x - 3 = 0
4x² -12x + x - 3 = 0
4x (x - 3) + 1(x - 3) = 0
(x - 3) (4x + 1) = 0
Using zero product property,
Either,
x - 3 = 0
x = 3
Or,
4x + 1 = 0
4x = -1
x = -1/4

Answer 2

Answer: $4 x^(2) -11x-3=0$
(4x+1)(x-3)=0
We can solve for x by setting each parentheses equal to 0
x= -1/4
x= 3

Use a calculator to compute the answer, and round it off to the nearest year.

10 is 5% of what number

Answers

We can use proportion to get the result
10 ----------- 5%
x ------------- 100%
Crossmultiply proportion

5*x=10*100
5x=1000 /:5 divide both sides by 5
x=1000:5
x=200 - its the answer

The correct answer for the question that is being presented above is this one: "C. 7.9 miles."

Area of the circle = pi * r^2
= pi * 100
= 314.15927.

It's traveled 45/360 = 1/8 of the circumference

Here are the following choices:
A. 0.8 miles
B. 4.5 miles
C. 7.9 miles
D. 12.5 miles

Step-by-step explanation:

Read the answer above/ below mine, I just wanted to point out that to solve this problem you use the circumference formula! The circumference of a circle is 2pi(r). r= radius= 10 (because 10 mi). Plug this into a calculator by typing: (20*pi) [division symbol] 8 =, and then it will give you 7.85..., but remember to round up to 7.9.

The correlation coefficient r between a child age x and the number of minutes spent doing homework each day y is 0.694.What percent of the variation?

A. 30.6%
B. 48.2%
C. 51.8%
D. 69.4%

Answers

The final answer to your question is that the percent variation of the correlation coefficient between a child age x and the number of minutes spent doing homework each day y with r = 0.694 is C. 51.8%.

Hope my answer would be a great help for you.

Answer:

The answer is 48.2%

Step-by-step explanation:

The correlation coefficient r between a child age x and the number of minutes spent doing homework each day y is 0.694 i.e r=0.694

Now, we have to find percent of the variation.

The coefficient of determination is $r^(2)$

The square of r(correlation coefficient) is the percent of variation that is explained by the dependent variable.

If r=0.694 ⇒ $r^(2)= (0.694)^(2)=0.482$ this means that 48.2% of variation in dependent variable.
