We need to find surface area, so we can imagine breaking it up into face net.

There will be 18 × 18 square base, four 18 × 40 rectangles, and four triangles with base 18 and height 13.

So the surface area would be sum of these areas.

That would be 18×18 + 4( 18 × 40 ) + 4( (1/2) 18×13 ) = 3672

Final answer: 3672 m²

Hope this helps.

Find the most general antiderivative of the function. (Check your answer by differentiation. Use C for the constant of the antid

vredina [299]

Answer:

$6t + \frac{t^2}{2}+2/5t^{5/2} + C$

Step-by-step explanation:

Given the expression;

g(t) = 6 + t + t²/√t

This can be rewritten as;

g(t) = 6 + t +t²/t^1/2

g(t) = 6 + t +t^{2-1/2}

g(t) = 6 + t +t^3/2

Integrate the result

$\int\limits {(6 + t+t^{3/2}}) \, dt\\$

Using the formula x^{n+1}/n+1

$\int\limits {(6 + t+t^{3/2}}) \, dt\\ = 6t + \frac{t^2}{2}+\frac{t^{3/2+1}}{3/2 + 1} \\ = 6t + \frac{t^2}{2}+\frac{t^{5/2}}{5/2} \\= 6t + \frac{t^2}{2}+2/5t^{5/2} + C$

3x-9y=9 -3x+4y=14 (1,-3) (6,1) (1,-8)

DENIUS [597]

3x - 9y = 9
-3x + 4y = -14

-5y = -5

y = 1

3x - 9(1) = 9

3x - 9 = 9

3x = 18

x = 6

So, the answer is (6, 1)

Plz help. find the solution for: 9-3 | x-2 | = 4 will give brainliest.

meriva

answer:

x=1/3

x=11/3

STEP 1:

Rearrange this Absolute Value Equation

Absolute value equalitiy entered

-3|x-2|+9 = 4

Another term is moved / added to the right hand side.

To make the absolute value term positive, both sides are multiplied by (-1).

3|x-2| = 5

STEP 2:

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is 3|x-2|

For the Negative case we'll use -3(x-2)

For the Positive case we'll use 3(x-2)

STEP 3:

Solve the Negative Case

-3(x-2) = 5

Multiply

-3x+6 = 5

Rearrange and Add up

-3x = -1

Divide both sides by 3

-x = -(1/3)

Multiply both sides by(-1)

x = (1/3)

Which is the solution for the Negative Case

STEP 4:

Solve the Positive Case

3(x-2) = 5

Multiply

3x-6 = 5

Rearrange and Add up

3x = 11

Divide both sides by 3

x = (11/3)

Which is the solution for the Positive Case

giving us x=1/3 or x=11/3

allso if u can i need help with a thing so plese help, i would aprestiate it

Find two unit vectors in 2-space that make an angle of 45◦ with 4i+3j.

inn [45]

First, lets transform the given vector into an unit vector (dividing by its module)

UnitVec = 4/5 i + 3/5 j

Then lets change this vector into a polar form

UnitVec = 1. with angle of 36.869 degrees taking as a reference the i vector

Then, the probem tells us that the vectors u and v make an angle of 45 degrees with UnitVec, so lets add+-45 to the vector in polar form

U = 1*[cos(36.869 +45)i + sin(36.869 +45)j] = 0.1414 i + 0.9899 j

V = 1*[cos(36.869 -45)i + sin(36.869 -45)j] = 0.9899 i - 0.1414 j
