$\bf \cfrac{3}{30}\implies \cfrac{3\cdot 1}{3\cdot 10}\implies \cfrac{3}{3}\cdot \cfrac{1}{10}\implies 1\cdot \cfrac{1}{10}\implies \cfrac{1}{10}$

Combine like terms to create an equivalent expression. 7.4z−5(−1.6z+2.4)

ryzh [129]

Answer: $15.4z-12$

Step-by-step explanation:

For this exercise it is important to remember:

The Distributive property:

$a(b\±c)=ab\±ac$

The multiplication of signs:

$(+)(+)=+\\\\(-)(-)=+\\\\(-)(+)=-$

Then, given the following expression:

$7.4z−5(-1.6z+2.4)$

You need to apply the Distributive property. Then:

$=7.4z+8z-12$

Now you can combine like terms (or add the like terms). Then you get:

$=15.4z-12$

Therefore, the equivalent expression created by combining like terms, is:

$15.4z-12$

Which ratio represents the value of sin Q

Volgvan

We know that :

$\bigstar \ \ \boxed{\sf{sin\theta = \dfrac{Opposite \ Side}{Hypotenuse}}}$

From the figure, We can notice that :

↔ Opposite side of Angle Q is 9 units

↔ Hypotenuse is 15 units

$\sf{\implies sinQ = \dfrac{9}{15}}$

$\sf{\implies sinQ = \dfrac{3}{5}}$

The power generated by an electrical circuit (in watts) as a function of its current ccc (in amperes) is modeled by: P(c)=-20(c-

alekssr [168]

Answer:

The current that produces maximum power is 3A

Step-by-step explanation:

Given

$P(c) = 20(c - 3)^2$

Required [Missing from the question]

The current that produces maximum power

First, we represent the function in standard form

$P(c) = 20(c - 3)^2$

$P(c) = 20(c - 3)(c - 3)$

Open bracket

$P(c) = 20(c^2 -6c+ 9)$

$P(c) = 20c^2 -120c+ 180$

The maximum value of c is:

$Max(c) = \frac{-b}{2a}$

Where:

$f(x) = ax^2 + b^2 + c$

By comparison: $P(c) = 20c^2 -120c+ 180$

$a = 20$

$b = -120$

$c = 180$

So, we have:

$Max(c) = \frac{-b}{2a}$

$Max(c) = \frac{-(-120)}{2 * 20}$

$Max(c) = \frac{120}{40}$

$Max(c) = 3$
