Answer:

Option D

Step-by-step explanation:

Find the difference: (6y3 + 17y − 3) − (4y3 − 11y + 9)

$(6y^3 + 17y - 3) - (4y^3 - 11y + 9)$

To find the difference, remove the parenthesis by multiplying the negative sign inside the parenthesis.

$6y^3 + 17y - 3 - 4y^3 + 11y - 9$

Now we combine like terms

$2y^3 + 28y -12$

So , its option D

3. Which inequalities show a correct relationship between expressions?

igomit [66]

Answer: a and d

Step-by-step explanation:

First of all, we need to make a analysis of each letters:

a. factoring 32 = 2.2.2.2.2 = $2^{5}$

$2^{5}^{3} = 2^{15}$

then,

16 = $2^{4}$

but $2^{4}^{4} =2^{16}$

in conclusion that, this inequality is correct

b. 27 = $3^{3}$

this first situation is equal to $3^{9}$

the second situation is:

81 = $3^{4}$

and $3^{4}^{4} = 3^{16}$

it's a mistake.

c. factoring 9: $9 = 3^{3}$

$3^{9}$ < $3^{5}$

it's wrong.

d. factoring 8 = $2^{3}$

factoring 32 = $2^{5}$

$2^{12}$ > $2^{10}$

This is true.

Finally.. our correct answers is a and d.

How to determine if a function is even or odd calculus?

aalyn [17]

A function $f(x)$ is even if $f(-x)=f(x)$ , and is odd if $f(-x)=-f(x)$ .

Example:

$f(x)=x^2$ is even, since $f(-x)=(-x)^2=x^2=f(x)$ .

$g(x)=x^3-x$ is odd, since $g(-x)=(-x)^3-(-x)=-x^3+x=-(x^3-x)=-g(x)$ .

For a study regarding mean cadence, two-way ANOVA was used. The two factors were walking device (none, standard walker, rolling

goldenfox [79]

Answer:

Step-by-step explanation:

With regards to the factor 'walking device used', the ANOVA conducted on the cadence data revealed a main effect of walking device, and also with the results of the experiment giving rise to a p - value less than 0.05, we can reject the null hypothesis which says, there is no effect of the walking device factor.

We can thus conclude that there is not enough statistics evidence to prove that there is no interaction between the two factors or that there is no effect of the walking device given the cadence data.

If x and y are 2 complementary angles then find the value of y if measure of angle x is 20 degree

schepotkina [342]

Answer:

y=70 degrees

Step-by-step explanation:

If 2 angles are complimentary, they add up to 90 degrees.

x+y=90 degrees

x=20 degrees

y=90-20 degrees

y=70 degrees

If that is wrong, try this. Let's say the questions gives us the fact that x is 20 degrees greater than y.

y=x

Substituting x for y, the equation is x+x+20=90

Since y is x, x would also be y, which is 35. then x+20 would be 55.

So y would be 35.

THE ANSWER WOULD BE 70 DEGREES, BUT IF THAT IS WRONG, DO THE SECOND ONE, WHICH IS 35
