Answer:

$0.78 or 78 cents.

Step-by-step explanation:

We have to calculate one third of the money $2.34.

First we will rewrite the question as :

$\frac{1}{3}$ of 2.34

= $\frac{1}{3}$ × 2.34

= $0.78

Convert it into cents

1 dollar = 100 cents

0.78 dollar = 100 × 0.78

= 78 cents

One third of $2.34 is $0.78 or 78 cents.

Calculate the lateral area of a rectangular prism with a base with measures of 5.6 in. and 4.3 in. and a height of 10 in.

juin [17]

One formula for the lateral area is
A = 2(LW + H(L+W))

Filling in the given numbers, you have ...
A = 2((5.6 in)·(4.3 in) + (10 in)·(5.6 in + 4.3 in))
= 2(24.08 in² + 99 in²)
= 246.16 in²

Find f(g(x)). State the domain of the composite function.<br> f(x) = 3x-2/x+1<br> g(x) = x+5/2x-3

AnnyKZ [126]

Answer:

ℝ - {(-2/3),(3/2)}

Step-by-step explanation:

We want the domain of f(g(x)). So, firstly, we have to find the domain for g(x) and, then, for f(g(x)).

- Domain of g(x): Since the expression is a fracion, we must exclude the values of x that make null the denominator. Hence,

$g(x)=\dfrac{x+5}{2x-3}\Longrightarrow 2x-3\neq 0\iff \boxed{x\neq\dfrac{3}{2}}$

- Domain of f(g(x)): We'll find its expression:

$f(x) = \dfrac{3x-2}{x+1}\\\\f(g(x)) = \dfrac{3g(x)-2}{g(x)+1}\\\\f(g(x)) = \dfrac{3\cdot\dfrac{x+5}{2x-3}-2}{\dfrac{x+5}{2x-3}+1}=\dfrac{~~~\dfrac{3(x+5)-2(2x-3)}{2x-3}~~~}{\dfrac{(x+5)+(2x-3)}{2x-3}}\\\\f(g(x)) =\dfrac{3(x+5)-2(2x-3)}{(x+5)+(2x-3)}=\dfrac{3x+15-4x+6}{x+5+2x-3}\\\\\boxed{f(g(x)) =\dfrac{21-x}{3x+2}}$

Now, once again, we have to exclude the values of x that make the denominator equals to zero. Thus,

$f(g(x)) =\dfrac{21-x}{3x+2}\Longrightarrow 3x+2\neq0\iff \boxed{x\neq-\dfrac{2}{3}}$

Lastly, we may write the domanin of f(g(x)):

$D(f(g(x)) = \left]-\infty,-\dfrac{2}{3}\right[\cup\left]-\dfrac{2}{3},\dfrac{3}{2}\right[\cup\left]\dfrac{3}{2},\infty\right[$

or, just writing in a shorter way:

$\boxed{D(f(g(x)) = \mathbb{R}-\left\{-\dfrac{2}{3},\dfrac{3}{2}\right\}}$

Use an addition or subtraction formula to find the exact value of the expression, as demonstrated in example 1. sin(105°)

LekaFEV [45]

105° can be expressed as 60°+45°. What we have then is sin(60°+45°). The sum pattern for sin is sin(a)cos(b)+cos(a)sin(b). We will fill in as follows: sin(60)c0s(45)+cos(60)sin(45). Now draw those special right triangles in the first quadrant to get the exact values for each. The sin of 60 is $\frac{ \sqrt{3} }{2}$ , the cos of 45 is $\frac{1}{ \sqrt{2} }$ , the cos of 60 is 1/2, and the sin of 45 is $\frac{1}{ \sqrt{2} }$ . When we put all that together we get $( \frac{ \sqrt{3} }{2} * \frac{1}{ \sqrt{2} } )+( \frac{1}{2}* \frac{1}{ \sqrt{2} })$ . Simplifying all of that we have $\frac{ \sqrt{3} }{2 \sqrt{2} } + \frac{1}{2 \sqrt{2} }$ . We can put that over the common denominator that is already there and get $\frac{1+ \sqrt{3} }{2 \sqrt{2} }$ . Not sure if that's simplified enough; you may be at the point in class where you are rationalizing your denominator, but I'm not sure, and if you're not, I don't want to confuse you.
