Answer:

$f(x) = 5 - (x - 4)^2$ .

Step-by-step explanation:

$f(x) = 5 - (x - 4)^2$

$f(x) = 5 - (x-4)*(x-4)$

$f(x) = 5 - (x^2 - 4x - 4x + 16)$

$f(x) = 5 - (x^2 - 8x + 16)$

$f(x) = 5 - x^2 + 8x - 16$

$f(x) = -x^2 + 8x - 11$ .

Hope this helps!

the diameter of a cylindrical construction pipe is 4 ft. if the pipe is 19 ft long, what s it’s volume?

choli [55]

Answer:

76 $\pi$ or 238.76 $units^{3}$

Step-by-step explanation:

The volume of a cylinder is V = $\pi r^{2} h$

Here the radius is r = $\frac{1}{2} d$ = $\frac{1}{2}(4)=2$

The height is given as 19 ft

Then plug in all the numbers into the equation

V = $\pi (2^{2})(19) = 76\pi = 238.76 units^{3}$

Can someone help me with this it's due today

natali 33 [55]

Answer:

37 centimeters

Step-by-step explanation:

First, since the triangles are similar, find out how much larger STR is than HIJ by finding an similar side and dividing the numbers. Since the only similar side that we know both numbers on it ST and HI, so we divide 10 by 4 to get the unit rate, which is 5/2. The missing side on STR is the bottom, so to get it, multiply 6, the bottom of the other triangle, by the unit rate, 5/2, to get the answer of 15. Then, perimeter is all of the sides added up, so 10+12+15=37 cm.

(hope this helps :P)
