In the xy plane what is the y intercept of the graph of the equation y=2(x+3)(x-4)

Answers

Answer 1

Answer: y intercept is when line crosses y axis or when x=0

set x=0
y=2(0+3)(0-4)
y=2*3*-4
y=-24

y intecept is -24

Based on the graph below, what are the solutions to the equation f(x) = g(x)?graph of function f of x equals 5 times x minus 2. Graph of function g of x equals x cubed minus 2 times x squared minus x plus 2

(A)x = −3.7, 0.5, 3.4
(B)x = −1, 1, 2
(C)x = −2, 2, 3
(D)x = −2, 0.6, 3.4

Answers

Answer:

The answer is the option D

$x=-2,0.6,3.4$

Step-by-step explanation:

we have

$f(x)=5x-2$

$g(x)=x^(3)-2x^(2)-x+2$

To solve the system of equations equate f(x) and g(x)

$f(x)=g(x)$

The solution of the system of equations is the intersection points both graphs

Using a graphing tool

see the attached figure

The solutions of x are

$x=-2,0.6,3.4$

The solutions to the equation f(x) = g(x) is −2, 0.6, 3.4.

The correct option is (A)

What is function?

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

given:

f(x)= 5x-2

g(x)= x³-2x²-x+2

Now, equate f(x)= g(x)

The solution is shown using graphical method.

By looking the graph, the graph of function g(x) touches the line f(x) at three point −2, 0.6, 3.4.

Hence, the solution of x will be −2, 0.6, 3.4.

Help me find y........

Answers

Answer:

Step-by-step explanation:

the sum of all angles in a quadrilateral must be 360º

y+88+25+35 = 360

y = 360=88-25-35

y = 212º

the sum of all angles in an octagon must be 1080º

45+45+140+140+6y = 1080

6y = 1080-90-280

6y = 710

y = 710/6

y=~ 118,3º

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.
