Step-by-step explanation:

(f/g)(x) means that you have to divide f(x) by g(x).

[tex]\frac{x^4-x^3+x^2}{-x^2}\\ -x^2+x-1[/tex]

When dividing exponents with the same base, you have to subtract the exponents to find the quotient.

When dividing with negatives, you have to switch the sign of the other number.

Answer:

Step-by-step explanation:

We know that "bending" means to force or shape something into a curve or certain angle.

Now, when we bend something we are actually using a pair of forces, not just one, because you can't bend using only one forces, that would imply using one hand which is impossible. Notice that you need to forces to be applied at different points in the same direction to create the curve, these forces must be applied a certain distance away from the equilibrium point which is between the points of application.

Therefore, there are two forces involves because we need to use two points of application to bend something.

Answer: c

Step-by-step explanation: 9*9*9*9*9

C. 9 x 9 x 9 x 9 x 9 is equivalent to 9⁵

Exponential form : It is an easier way to write repeated multiplication of a number or variable using base(number or variable) and exponents.

Example : 6⁵ is the exponential form of 6×6×6×6×6 (i.e. 5times)

Here, given expression is 9⁵

So, in this expression, 9 multiplied 5 times, i.e. 9×9×9×9×9

Step-by-step explanation:

Answer:

y=18.51

Step-by-step explanation:

First we must figure out the value of "x". We can do that in the first equation. To find the value of "x" you divide both sides by 20. That will give you the value of "x" which is 2.7. With this information, you can plug in that value into the second equation to get the value of "y". 2(2.7)(y)=100. Multiply 2 and 2.7 to get 5.4. Then divide 5.4 from both sides to get the value of "y" which is around 18.51. I hope this helped.

Answer:

x raise to 6/7

Step-by-step explanation:

since the base of both the numbers on the numerator is same,

4/7 + 3/7 = 7/7

so, x raise to 7/7

then since the base is same for the numerator and denominator,

7/7-1/7= 6/7

so x raise to 6/7

Answer:

8/25

Step-by-step explanation:

We do this by multiplying the top first, and we get 32.

We then multiply the bottom, and get 100.

You might think the answer is 32/100.

Well, kind of! We need to simplify!

we divide the top and bottom by four to get our answer, 8/25.

Answer:

x= 4/9

Step-by-step explanation:

-1/(2x) + 1/8 = -1/(3x) - 1/4

-1/(2x)+1(3x)= - 1/4 -1/8

-3/(6x)+2(6x) = -2/8 -1/8

- 1/(6x) = - 3/8

-1*8 = -3*6x

8=18x

x= 8/18= 4/9

Check:

-1/(2*4/9) + 1/8 = -1/(3*4/9) - 1/4

- 1(8/9) + 1/8 = - 1/(4/3)-1/4

-9/8+1/8 = - 3/4-1/4

-1 = -1

Step-by-step explanation:

The shape which is congruent to the given shape is shape D.

Congruent figures are defined as the figures which are exact copies of each other.

That is, the dimensions and angles are equal.

Here given a shape which is in the shape of a parallelogram.

Options A and C are not congruent figures since they are not even a parallelogram.

Option B is a parallelogram which can be clearly seen that there is more width.

Option E is also not the one since it is smaller in size.

The congruent figure is thus, option D.

Hence the correct option is D.

Answer:

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

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

Step-by-step explanation:

Open the brackets first:

[tex]4x^2+9=18-12x[/tex]

Simplify:

[tex]4x^2+12x-9=0[/tex]

It is determined that this can't be factored, so rewrite the equation so you can complete the square.

[tex]x^2+3x=\frac{9}{4}[/tex]

Take the square of 1.5 and add it to both sides:

[tex]x^2 + 3x+ \frac{9}{4} =\frac{9}4} +\frac{9}{4}[/tex]

Factor:

[tex](x+\frac{3}{2})^2=\frac{9}{2}[/tex]

[tex]x+\frac{3}{2} = \frac{3\sqrt{2} }{2 }[/tex]

or [tex]x+\frac{3}{2} =-\frac{3\sqrt{2} }{2}[/tex]

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

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

Step-by-step explanation:

Answer:

x = 4 and y = 1

Step-by-step explanation:

3x+2y=14

2x-4y=4

We can solve them by canceling out one variable so we only have one variable left. Let's cancel out y by doubling the first equation. We get:

6x + 4y = 28

add that on to the second one and we get:

8x = 32

x = 4

We plug in x and get that:

y = 1

So in the end we get

x = 4 and y = 1

Let x represent distance between the base of the tower and the fire.

We have been given that a forest forest ranger is on a lookout tower in a forest. His observation tower is 214.7 feet above the  ground when he spots an illegal forest fire. The angle of elevation from the fire to the top of  the lookout is 78 degrees.

To find the distance between the base of the tower and the fire, we will use trigonometric ratio.

First of all, we will draw a right triangle using our given information as shown in the attached image.

We can see that x is adjacent side and 214.7 is opposite side to angle 78 of degrees.

[tex]\tan=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]

[tex]\tan(78^{\circ})=\frac{214.7}{x}[/tex]

[tex]x=\frac{214.7}{\tan(78^{\circ})}[/tex]

[tex]x=\frac{214.7}{4.704630109478}[/tex]

[tex]x=45.63589379[/tex]

Upon rounding to nearest tenth, we will get:

[tex]x\approx 45.6[/tex]

Therefore, the distance between the base of the tower and the fire is approximately 45.6 feet.
