What is 1 10th of 800grams

1 answer:

3 0

So, I understand that you one 1/10th, that is one tenth or $\frac{1}{10}$

so:

$\frac{1}{10}$ *800= $\frac{800}{10}$ =80

The answer is 80.

I calculated this by dividing both the nominator and the denominator by the same number - this is always allowed. This number is 10.

Find dy/dx by differentiating implicitly x^2y+3xy^3-x=3

AleksandrR [38]

$\dfrac{\mathrm d}{\mathrm dx}\left[x^2y+3xy^3-x\right]=\dfrac{\mathrm d}{\mathrm dx}[3]$
$2xy+x^2\dfrac{\mathrm dy}{\mathrm dx}+3y^3+9xy^2\dfrac{\mathrm dy}{\mathrm dx}-1=0$
$(x^2+9xy^2)\dfrac{\mathrm dy}{\mathrm dx}=1-2xy-3y^3$
$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{1-2xy-3y^3}{x^2+9xy^2}$

Answer:

D. f(x) = x - 4

Step-by-step explanation:

If you plug in the x values for the expression x - 4:

3 - 4 = -1
4 - 4 = 0
5 - 4 = 1
6 - 4 = 2
This means that the function rule is f(x) = x - 4
Hope this helps :)

Please find the fully simplified intercept form!!!! Will mark Brianliest !!!!!!!!!!!

Answer:

y = -1/3x - 8

Step-by-step explanation:

Slope intercept form:

y = mx + b

Use two points from the graph:

(0, -8) and (3, -9)

The first point is the y-intercept:

b = -8

Find the slope using the slope formula:

m = (y2 - y1)/(x2 - x1)
m = (-9 - (-8))/3 = -1/3

The equation is:

y = -1/3x - 8

1. m∠QPR = 2. m∠QTP = 3. RP = Show all the work

alex41 [277]

Answer:

1. 30°

2.90°

3. 12 units

Step-by-step explanation:

I can't believe there's nothing confirming that this is a parallelogram/a rhombus?! Assuming is awful, and I wish you could say you can't know for sure lol but for the sake of this answer, let's just call it a rhombus. (There was probably some context elsewhere that you didn't put over here, hopefully.)

The reason I say this is: in a rhombus, the diagonals bisect the angles. This means that the diagonals split the angles they meet into two equal parts. That way, it would make sense. m∠QPR=m∠SPR=30°.

If it is a rhombus, the diagonals are perpendicular to each other, so m∠QTP should be 90°.

Diagnonals in a rhombus (and in any parallelogram) bisect each other, so PT=TR=6, and RP=PT+TR=12 units.

Sorry if this is all dreadfully wrong, and I hope I helped you!

Find the length of side x in simplest radical form with a rational denominator.

Salsk061 [2.6K]

Answer: 5/2

Explanation:

According to 30-60-90 triangle rule:

The side opposite of 30 degree is equal to half of the hypotenuse and the hypotenuse here is 5 so therefore x = 5/2
