The top t appears to be the hypotenuse of a right triangle with angle 14.5 degrees amd opposite side 6.

$\sin 14.5^\circ = \dfrac{6}{t}$

$t = \dfrac{6}{\sin 14.5} \approx 23.96 \textrm{ inches} \approx 24 \textrm{ in}$

Which of the following functions is graphed below?

xxTIMURxx [149]

Answer: A is correct.

Explanation:

We can see f(x) is piece wise function and break at point x=2

When x<2

f(x) is parabolic whose y-intercept (0,4)

So, $f(x)=x^2+4$

When $x\geq2$

f(x) is linear with slope 1

So, $f(x)=x+4$

A is correct option according to given graph.

$f(x)=\left\{\begin{matrix}x^2+4 & \ \ \ \ \ \ \ x$

P(x)⋅Q(x)=R(x); if P(x)=x+1 and R(x)=2x3+2x2+3x+3, what is Q(x)?

IceJOKER [234]

Answer: B

Step-by-step explanation:

$P(x) Q(x)=R(x) \implies Q(x)=\frac{R(x)}{P(x)}\\\\Q(x)=\frac{2x^{3}+2x^{2}+3x+3}{x+1}={2x^{2}(x+1)+3(x+1)}{x+1}=\boxed{2x^{2}+3}$

What is the x value with that y =15 -3x and y =0?

kumpel [21]

$\bf y=15-3x~\hspace{5em} \stackrel{y=0}{0=15-3x}\implies 3x=15\implies x=\cfrac{15}{3}\implies x = 5$
