Write an expression for the sequence of operations described below. triple u, then multiply t by the result
nikklg [1K]

Answer:

t(3u)

Step-by-step explanation:

First we have to triple (x3) u, which is what gets us 3u.  Then we multiply that result by t.  

This gives us:  t(3u)

Remember, this problem is asking for you to write an expression, not and equation.  That is why there is not an equal sign included in the answer.

Calculate the value of angle A and C of ∆ ABC. Where b=1435cm, a= 782cm and B= 115.6°.​
Monica [59]

The Law of Sines says

\dfrac{\sin A}{a} = \dfrac{\sin B}{b} = \dfrac{\sin C}{c}

\sin A = \dfrac a b \sin B

A = \arcsin( \dfrac{782}{1435} \sin 115.6 ) = 29.44^\circ

We don't have to worry about the obtuse supplement because a triangle can only have one obtuse angle, and that's B.

C = 180 - 115.6 - 29.44 = 34.96^\circ

Answer: A=29.44°, C=34.96°

Answer is –4/5

Rearrange the equation to make y the subject

5y = –4x – 35

y = –4/5 x – 7

If the line is parallel to the other line, they both have the same gradients but different y-intercepts, so the gradient is just as is.

solve the following and explain your steps. Leave your answer in base-exponent form. (3^-2*4^-5*5^0)^-3(4^-4 over 3^3)*3^3 Pleas
Jobisdone [24]

Answer:

  3^64^{11}

Step-by-step explanation:

It appears you're trying to simplify ...

  (3^{-2}4^{-5}5^0)^{-3}\cdot\dfrac{4^{-4}}{3^3}\cdot 3^3

The final factor cancels the denominator of the fraction, so we have ...

  3^{(-2)(-3)}4^{(-5)(-3)-4}=3^64^{11}

_____

The applicable rules of exponents are ...

  (ab)^c = (a^c)(b^c)

  (a^b)(a^c) = a^(b+c)

  (a^b)^c = a^(bc)
