A plane is flying from one airport to another. Would it be better to use a globe or a flat paper map to find the shortest distan

nadezda [96]

Answer:

Using a globe and some string might be more convenient. A great circle is the shortest path between any two points on the earth's surface.

Find the zeros of the following

julia-pushkina [17]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

13 ) Go...

$f(x) = {x}^{2} - 2x$

$0 = {x}^{2} - 2x$

${x}^{2} - 2x = 0$

Factor x

$x(x - 2) = 0$

$x = 0 \: \: \: or \: \: \: x - 2 = 0$

$x = 0 \: \: \: \: or \: \: \: \: x = 2$

These are the zeroes.

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

14 ) Go...

$f(x) = {x}^{3} + 9x + 11x - 21$

$0 = {x}^{3} + 9 {x}^{2} + 11x - 21$

${x}^{3} + 9 {x}^{2} + 11x - 21 = 0$

$(x - 1)(x + 3)(x + 7) = 0$

$x - 1 = 0 \: \: or \: \: x + 3 = 0 \: \: or \: \: x + 7 = 0 \\$

$x = 1 \: \: \: or \: \: \: x = - 3 \: \: \: or \: \: \: x = - 7 \\$

These are the zeroes.

Charles begins finding the volume of a trapezoidal prism using the formula A = One-half(b1 + b2)h to find the prism's base area.

yKpoI14uk [10]

Answer:

The expression that can be used to represent the volume of the trapezoidal prism is $(2x^3+6x^2)$

Step-by-step explanation:

step 1

Find the area of the trapezoidal base

The area of a trapezoid is given by the formula

$A=\frac{1}{2}(b_1+b_2)h$

we have

$b_1=(x+2)\ units\\b_2=(x+4)\\h=x$

substitute

$A=\frac{1}{2}(x+2+x+4)x$

$A=\frac{1}{2}(2x+6)x$

$A=(x+3)x\\A=(x^2+3x)\ units^2$

step 2

Find the volume of the trapezoidal prism

we know that

The volume of the prim is given by

$V=Bh$

where

B is the area of the base

H is the height of the prism

we have

$B=(x^2+3x)\ units^2$

$H=2x\ units$

substitute

$V=(x^2+3x)2x\\V=(2x^3+6x^2)\ units^3$

therefore

The expression that can be used to represent the volume of the trapezoidal prism is

$(2x^3+6x^2)$

Solving for y what is 3x-4y=-8<br> solving for y what is 3x-4y=-8

Sati [7]

Answer:

y=2+0.75x

Step-by-step explanation:

3x-4y=-8

first, subtract 3x from both sides

-4y=-8-3x

now divide by -4

y=2+0.75x
