Which of the following numbers has the correct number of significant digits for the sum of 4.0125 and 5.72?

A. 9.7324
B. 9.732
C. 9.73
D. 9.7

Answers

Answer 1

Answer:

the answer to your question is 9.73

Answer 2

Answer:

A

Step-by-step explanation:

Because according to my calculations there are supposed to be 5 digits and for the answers for the question A is the only letter with an answer with 5 digits.

My answer was 9.7325(even though the answers is different they still have the same number of digits) and for A it is 9.7324 which is another 5 digits.

Here is why I got 5 digits.

4.0125

5.7200

_______

When we add these we have to add 0er's to 5.72 because it doesn't have enough digits to add so you add zero's to it.

So 5 +0=5  2 +0=2  1 +2=3  0 +7=7  and for our last number 4 + 5=9 and so our answer is ?

9.7325

and the 9 = 1 digit 7=2 digit 3= 3 digits 2= 4 digits and last 5 = 5 digits.

Hope this helps have a great day:)

-2x + y = 7

A. (-2,11)

B. (2.11)

C. (7,0)

D. (1.5)

Answers

Answer:

B

Step-by-step explanation:

Plug in coordinates to see if they match the answer.

It's easier in slope-intercept form, so lets change it first.

-2x+y=7

+2x    +2x

y=2x+7

Now we can plug in the coordinates to see if they match.

Lets try A.

11=2(-2)+7

11=-4+7

11=3

A is incorrect.

Lets try B.

11=2(2)+7

11=4+7

11=11

B is a solution, therefore is on the graph.

part one is -3 and 7
part two is -3

Answers

Answer:

Given equation:

[tex]\sqrt{30-2x} =x-3[/tex]

Square both sides:

[tex]\implies (\sqrt{30-2x})^2 =(x-3)^2[/tex]

[tex]\implies 30-2x =(x-3)^2[/tex]

Expand the right side:

[tex]\implies 30-2x =x^2-6x+9[/tex]

Add [tex]2x[/tex] to both sides:

[tex]\implies 30 =x^2-4x+9[/tex]

Subtract 30 from both sides:

[tex]\implies x^2-4x-21=0[/tex]

Factor:

[tex]\implies (x-7)(x+3)=0[/tex]

Therefore,

[tex]x-7=0 \implies x =7[/tex]

[tex]x+3=0 \implies x=-3[/tex]

Substitute both values of [tex]x[/tex] into the original equation to check:

[tex]x=7 :[/tex]

[tex]\implies\sqrt{30-2(7)} =7-3[/tex]

[tex]\implies 4=4[/tex]

correct!

[tex]x=-3[/tex]

[tex]\implies\sqrt{30-2(-3)} =-3-3[/tex]

[tex]\implies 6 \neq =-6[/tex]

incorrect!

Therefore, [tex]x=7[/tex] is the only correct solution, and [tex]x=-3[/tex] is the extraneous solution

What is the exact value of tan

Answers

Answer:

[tex]\displaystyle -\sqrt{3} - 2[/tex]

Explanation:

If you recall the unit circle [from the polar graph], you would have no trouble at all figuring this out, but sinse you have trouble, do not worry about it. So, here is what you should have realised:

[tex]\displaystyle \boxed{1\frac{1}{2}\pi} = \frac{18}{12}\pi[/tex]

If you did not notise, [tex]\displaystyle 1\frac{7}{12}\pi,[/tex]or [tex]\displaystyle \frac{19}{12}\pi,[/tex]is just [tex]\displaystyle \frac{\pi}{12}[/tex]more than [tex]\displaystyle 1\frac{1}{2}\pi,[/tex]which means the exact value will either be a radical, followed by an integer or just a radical. In this case, accourding to the unit circle, you will have a radical, followed by an integer, and that will be this:

[tex]\displaystyle \frac{sin\:1\frac{7}{12}\pi}{cos\: 1\frac{7}{12}\pi} = tan\:1\frac{7}{12}\pi \\ \\ \boxed{-\sqrt{3} - 2} = \frac{sin\:1\frac{7}{12}\pi}{cos\: 1\frac{7}{12}\pi}[/tex]

It is all about memorisation of the unit circle, which I know is difficult, but you will get used to it soon.

*Now, if you had to find [tex]\displaystyle cos\:\frac{7}{12}\pi,[/tex]then the exact value would be the OPPOCITE of the exact value of [tex]\displaystyle sin\:\frac{7}{12}\pi,[/tex]which is [tex]\displaystyle -\frac{\sqrt{2} + \sqrt{6}}{4},[/tex]because you would be crossing into the second quadrant where the x-coordinates are negative, accourding to both the cartesian and polar graphs. In addition, sinse you ALREADY have both values for sine and cosine [accourding to your PREVIOUS QUESTION ASKED], all you need to do is divide both values in the order given above to arrive at the exact value for [tex]\displaystyle tan\:1\frac{7}{12}\pi.[/tex]

No difference in femininity based on contrast between eye color and skin tone.
Alternative hypothesis or H(a) basically contradicts that, so in this case:

Answers

The equation of the sum of any two squares x and y is x^2 + y^2 = (x + y)^2 - 2xy

How to determine the last digit

The question is incomplete, as there are no parameters to determine the last digit of the first number.

So, I will give a general explanation

The sum of squares of two numbers x and y is:

[tex]x^2 + y^2 = (x + y)^2 - 2xy[/tex]

Assume the numbers are 5 and 6, then the equation becomes

[tex]5^2 + 6^2 = (5 + 6)^2 - 2*5*6[/tex]

Evaluate

[tex]5^2 + 6^2 = 61[/tex]

A banner is hung for a party. The distance from a point on the bottom edge of the banner to the floor can be determined by using the function f(x) = 0.25 x2 − x + 9.5 , where x is the distance, in feet, of the point from the left end of the banner. How high above the floor is the lowest point on the bottom edge of the banner? Explain.

Answers

That's possible when function tends to zero

[tex]\\ \rm\hookrightarrow 0.25x^2-x+9.5=0[/tex]

[tex]\\ \rm\hookrightarrow x^2-x+38=0[/tex]

[tex]\\ \rm\hookrightarrow x=\dfrac{1\pm\sqrt{1-152}}{2}[/tex]

[tex]\\ \rm\hookrightarrow x=\dfrac{1\pm\sqrt{151}i}{2}[/tex]

Answer:

8.5 ft

Step-by-step explanation:

[tex]f(x) = 0.25x^2 - x + 9.5[/tex]

To find the minimum point of the function, differentiate:

[tex]f'(x) = 0.5x - 1[/tex]

set to zero and solve for x:

[tex]f'(x) =0\\ \implies0.5x - 1=0\\\implies x=2[/tex]

Substitute found value of x into function to find y (height):

[tex]f(2) = 0.25(2)^2 - 2 + 9.5=8.5[/tex]

Therefore, the lowest point on the bottom edge of the banner is 8.5 ft above the floor.
