BC=<br> Round your answer to the nearest hundredth.

mrs_skeptik [129]

Answer:

BC ≈ 1.71

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos70° = $\frac{adjacent}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{BC}{5}$

Multiply both sides by 5

5 × cos70° = BC , thus

BC ≈ 1.71 ( to the nearest hundredth )

Find the average rate of change for f(x)=9x^2+3 over the interval [x,x+h].

butalik [34]

Answer:

$9h +18x$

Step-by-step explanation:

$\frac{f(x +h) -f(x)}{x+h -x} \\ \frac{9(x +h)^2 +3 -(9x^2 +3)}{h} \\ \frac{9(x^2 +2xh +h^2) +3 -9x^2 -3 }{h} \\ \frac{9x^2 +18xh +9h^2 +3 -9x^2 -3}{h} \\ \frac{9h^2 +18xh}{h} \\ 9h +18x$

Math help, I'm stuck with my homework and I want to get it done.

ivann1987 [24]

Answer:

m = $\frac{1}{4}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 4x + 7 is in this form with slope m = - 4

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-4}$ = $\frac{1}{4}$

Hence the value of m = $\frac{1}{4}$
