Answer:

Step-by-step explanation:

x*x*x=x^3 (x cubed)

x*x=x^2 (x squared)

We CAN'T add up x's here.

They're from different families.

So, B is correct:)

The measure of an angles suppliment is 53° more than twice that of its compliment. find the angle.

Anettt [7]

(180-x)-2(90-x)= 53
Remember that complimentary angles add to 90 and supplementary angles add to 180.

180-x-180+2x=53
x=53

Final answer: The angle is 53 degrees.

need help with this Drag the points to create graphs of linear relationships that have different y-intercepts and slopes of 1/5,

ludmilkaskok [199]

Linear relationships that have different y-intercept and slope of 1/5 is y=1/5 x+25/6.

Given that, the slopes are 1/5, 3/5 and 6/5.

<h3>What is slope of a line?</h3>

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The coordinate points from the given figure are (6, 5), (5, 1) and (4, 3).

Substitute m=1/5 and (x, y)=(6, 5) in y=mx+c, we get

5=1/5 ×6+c

⇒ c=5- 5/6

⇒ c=25/6

Put m=1/5 and c=25/6 in y=mx+c, we get

y=1/5 x+25/6

Substitute m=3/5 and (x, y)=(5, 1) in y=mx+c, we get

1=3/5 ×5+c

⇒ c=-2

Put m=3/5 and c=-2 in y=mx+c, we get

y=3/5 x-2

Substitute m=6/5 and (x, y)=(4, 3) in y=mx+c, we get

3=6/5 ×4+c

⇒ c=3-24/5

⇒ c= -9/5

Put m=6/5 and c= -9/5 in y=mx+c, we get

y=6/5 x-9/5

Therefore, linear relationships that have different y-intercept and slope of 1/5 is y=1/5 x+25/6.

Write the linearization of the function at the points indicated. (Enter your answer as an equation. Let x be the independent var

Natalija [7]

Answer:

$\displaystyle y=5+\frac{x}{10}$

$\displaystyle y=10+\frac{(x-75)}{20}$

Step-by-step explanation:

<u>Linearization</u>

It consists of finding an approximately linear function that behaves as close as possible to the original function near a specific point.

Let y=f(x) a real function and (a,f(a)) the point near which we want to find a linear approximation of f. If f'(x) exists in x=a, then the equation for the linearization of f is

$y=f(x)=f(a)+f'(a)(x-a)$

Let's find the linearization for the function

$y=\sqrt{25+x}$

at (0,5) and (75,10)

Computing f'(x)

$\displaystyle f'(x)=\frac{1}{2\sqrt{25+x}}$

At x=0:

$\displaystyle f'(0)=\frac{1}{2\sqrt{25+0}}=\frac{1}{10}$

We find f(0)

$f(0)=\sqrt{25+0}=5$

Thus the linearization is

$\displaystyle y=f(0)+f'(0)(x-0)=5+\frac{1}{10}x$

$\displaystyle y=5+\frac{x}{10}$

Now at x=75:

$\displaystyle f'(75)=\frac{1}{2\sqrt{25+75}}=\frac{1}{20}$

We find f(75)

$f(75)=\sqrt{25+75}=10$

Thus the linearization is

$\displaystyle y=f(75)+f'(75)(x-75)=10+\frac{1}{20}(x-75)$

$\displaystyle y=10+\frac{(x-75)}{20}$

Clara is leaving her uncle's house to go to her house. After driving 2 hours at a steady rate, Clara is 79 miles from her house

topjm [15]

If you use your subtraction right when you use deceleration as for example like 4.5 from 79 well you know it had to slow down so the correct Answer for this would end up as 17 .5 Try the easy way like

79 dived by 4.5 would get you the same answer but don't divide backwards you will get an in correct answer

hope i helped;)
