What is the height of the triangular prism below if the volume equals 1,638 cubic millimeters? 65 mm 63 mm 26 mm 28 mm.

sergejj [24]

Answer:

The height of the triangular prism is $26\ mm$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The volume of the triangular prism is equal to

$V=Bh$

where

B is the area of the triangular base

h is the height of the prism

Find the area of the base B

$B=\frac{1}{2}(7)(18)=63\ mm^{2}$

we have

$V=1,638\ mm^{3}$

$h=x\ mm$

substitute and solve for x

$1,638=(63)x$

$x=1,638/(63)=26\ mm$

State the number of possible real zeros and turning points of f(x) = x7 – 6x6 + 8x5. Then determine all of the real zeros by fac

Rudiy27

Answer:

steps below

Step-by-step explanation:

f(x) = x⁷ – 6x⁶ + 8x⁵

f'(x) = 7x⁶ - 36x⁵ + 40x⁴

= x⁴ (7x² - 36x + 40) ... (1)

Critical point (x,y): x = 0 , x = (36 ± √(-36)²-4*7*40) / (2*7) = (18±2√11) / 7

x = 0 or x = 3.5 or x = 1.6

plug into (1): y = 0 , y = -394.3 , y = 10.1

extreme : maximum (1.6 , 10.1) minimum (3.5 , -394.3) ... turning points

x⁷ – 6x⁶ + 8x⁵ = x⁵ (x² - 6x + 8) = x⁵ (x-2) (x-4) =0

real zeros: x = 0, x=2, x=4

Could someone help me with this pls

barxatty [35]

Answer:

7.99

Step-by-step explanation:

using the formula

$v = \pi \: r ^{2} h$

$3014.4 = 22 \div 7 \times r ^{2} \times 15$

$21100.8 = 22 \times 15 \times r {}^{2}$

$21100.8 = 330 \times r {}^{2}$

$21100.8 \div 330 = r {}^{2}$

$\sqrt{63.94 }= r$

$r = 7.99ft \: answer$
