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:)

Which is bigger 11/18 or 5/14

KengaRu [80]

Among the fractions given in this question 11/18 and 5/14, the largest fraction is: 3/5.

Step-by-step explanation:

To find out which fraction is the largest, just divide the numerator by the denominator of the ratio and make the comparisons between them, thus defining which is the largest by decimal places or the largest number.

Resolution:

$\large \sf \dfrac{11}{18} \rightarrow 11\div18\rightarrow 0{,}61111111111$

$\large \sf \dfrac{5}{14} \rightarrow 5\div14\rightarrow 0{,}35714285714$

Conclusion:

We can conclude that the largest fraction, being between 11/18 and 5/14, is 11/18.

karie builds a skate ramp with 2 metres of wood. she wants the vertical height of the ramp to be 1 metre. what does the angle el

MA_775_DIABLO [31]

9514 1404 393

Answer:

30°

Step-by-step explanation:

The relationship between triangle sides and angles can be remembered using the mnemonic SOH CAH TOA. Here, we're interested in the relationship involving the hypotenuse and the side opposite the angle:

Sin = Opposite/Hypotenuse

For a ramp 1 m high and 2 m long, we have ...

sin(x) = (1 m)/(2 m) = 1/2

x = arcsin(1/2) = 30°

The elevation angle of the ramp needs to be 30°.

What are the key features of a graph of a quadratic equation with only complex solutions

dybincka [34]

Answer:

If D< 0, the roots of the quadratic equation will b complex.

Step-by-step explanation:

Let $ax^{2} + bx + c =0$ is the given quadratic equation.

So, if the Discriminant (D) = $b^{2} - 4ac < 0$ , the the equation will have only complex solutions.

Complex roots are represented in the form of $(x \pm iy)$

1. x represents the X axis (real) co ordinate,

y represents the Y axis (imaginary) coordinate

2. Also, the graph of the with equation D < 0 NEVER CROSSES the X - axis, as there are no real roots of the equation, only complex roots.

3. Here. roots are always identical but are opposite in signs. Such pair or roots with opposite sign are called CONJUGATE PAIRS.
