9/8x²+2x-15 - 5/2x³+3x + 4/4x²-5x​

Mathematics
1 answer:
elena-s [515]2 years ago
6 0

Answer:

-\frac{5}{2} x^{3} +\frac{17}{8} x^{2} -15

Step-by-step explanation:

First combine like terms so for numbers with x^3 you have one:

-\frac{5}{2} x^{3}

Then x^ 2

\frac{9}{8}x^{2} +x^{2}

(4/4x^2 is just x^2 because 4/4 is 1)

So

\frac{17}{8} x^{2}

Then all numbers with x cancel out because

2x+3x-5x is 0.

Then you just have -15.

So put them back together to get what I wrote in the answer.

Hope that helps lmk if I calculated that wrong!

In order to solve the formula

C=\pi d

in terms of d, you simply have to divide both sides by pi:

d=\dfrac{C}{\pi}

The total height of the earring is the sum of the diameters of the circles. Given their circumferences, the diameters are

d_1=\dfrac{6}{\pi},\quad d_2=\dfrac{8}{\pi}

So, the total height is

h=d_1+d_2=\dfrac{6}{\pi}+\dfrac{8}{\pi}=\dfrac{14}{\pi}

if you could generate energy by fusing the hydrogen in solution a, how much of the solution would you need to generate the elect
iogann1982 [59]

Answer:

We know that:

Energy released by fusion of hydrogen in 1 liter of solution A = 7.6x10^10 J

Energy used daily in a certain family home = 3x10^4 J

(you did not write the units, so i suppose that are the same in both cases)

Then, if x is the number of liters of solution A used, the energy produced will be:

E(x) = x*7.6x10^10 J

And we want this equal to 3x10^4

then:

E(x) = x*7.6x10^10 J = 3x10^4 j

now we solve this for x.

x = (3x10^4 j)/(7.6x10^10 j) = 3.9x10^-7

Then you need to use 3.9x10^-7 L of solution a.

Find the value of x in the triangle shown below.<br> x =<br> 98°<br> 27°
Levart [38]

Answer: 55

Step-by-step explanation: There is one simple theorem we need to know in order to solve for this.

Triangle Angle-Sum Property: All three angles interior angles of a triangle add up to 180°.

Thus, we could label the points A, B, and C, and set up an algebraic expression.

Let A = 27, B = 98, and C = x.

A + B + C = 180°.

Substituting A, B, and C we get:

27 + 98 + x = 180°.

Adding, we get:

125 + x = 180°

Subtracting 125 by 180, we get:

x = 55°

Thus, the angle X is 55°.

We could have simply solved this by just doing 180 - 98 - 27 = 55 in the first place, but I wanted to show you how I got such results.
