Answer:

21

Step-by-step explanation:

n+7=3n ⇒ 2n=7 ⇒ n= 3.5

VX= 2*(n+7) = 2*(3.5+7)= 21

in case you need

WY= 2*(4n+1)= 2*(4*3.5+1)= 30

If the m∠1=123° m ∠ 1 = 123 ° and m∠2= (2x+7)° m ∠ 2 = ( 2 x + 7 ) ° , determine the value of x that supports l∥m l ∥ m . Show y
Georgia [21]

Answer:

25

Step-by-step explanation:

Let us assume that m<1 nad m<2 are supplementary. Since the sum of supplementary angles is 180degrees, hence;

<1 + <2= 180

123+2x+7 = 180

130+2x = 180

2x = 180 - 130

2x = 50

x = 50/2

x = 25

Hence the value of x is 25

A cylinder has a base diameter of 14m and a height of 15m. What is its volume in
BabaBlast [244]

Answer:

2310m^3

Step-by-step explanation:

base area which is the circle = πr^2

But diameter, d = 14, r = 14/2 = 7

area = π × (7)^2 = 22/7 × 49 = 22 × 7 = 154

Volume = base area × height

= 154 × 15 = 2310

Which line has an equation of y=-5x+4 in slope-intercept form?
tino4ka555 [31]

You can figure the line for each pair of points, or you can try the points in the equation you have and see which are on the line.


First answer: x=1, y=-5×1 +4 = -1 . . . not 9. (1, 9) is not a point on the line


Second answer: x=2, y=-5×2 +4 = -6 . . . not -14. (2, 14) is not a point on the line


Third answer: (see the calculation for the first answer) . . . -1 ≠ 1. (1, 1) is not a point on the line


Fourth answer: (see the calculation for the second answer) We know that (2, -6) is on the given line. Checking (4, -16), we find it is as well.



The appropriate choice is the 4th answer:

... a line passing through the points (2, -6) and (4, -16)

Plzzz Helpp with this!!!!
Travka [436]

f(g(11)) = -6

Solution:

Given data:

f(x)=x^{2}-6 x+3

g(x)=\sqrt{x-2}

<u>To find f(g(11)):</u>

Substitute x = 11 in g(x).

g(11)=\sqrt{11-2}

        =\sqrt{9}

g(11)=3

Substitute g(11) = 3 in f(g(11)).

f(g(11))=f(3)

f(x)=x^{2}-6 x+3

f(3)=3^{2}-6 (3)+3

f(3)=9-18+3

f(3)=-6

f(g(11))=f(3)

             = -6

Hence f(g(11)) = -6.
