Answer:

1204 in²

Step-by-step explanation:

To find the area of a trapezoid, use the following formula: [tex]\frac{b_{1} + b_{2} }{2} h[/tex]. First add the two bases together: 46 + 40 = 86. Now divide that by 2: 86/2 = 43. Now multiply this by the height (28): 43 x 28 = 1204. This is your area: 1204 in².

Hope it helps!

Answer:

24.75 ft

Step-by-step explanation:

a) Maximum: 10

b) Minimum: - 2

To determine the amplitude we first recognize the midline, so I will answer part d first,

d) We have our maximum as 10, and our minimum as - 2. The midline, by it's name, is a line that divides the graph in half. What we do is determine the average of 10 and - 2 => 10 - 2/2 = 8/2 = 4

Midline: y = 4

Now I will go back to part c,

c) The amplitude would be 6. We take the difference between the maximum and the midline, or the minimum and the midline.

e) Period => The difference between two respective points on the graph

=> 3π/2 - π/2 = π, Period = π

f) We know that the period = π...

2π/b = π, b = 2π/π = 2

Answer:

Four possible values of x: 10, 3, 20, 31

Writing it in ascending order : 3, 10, 20, 31, 33

Step-by-step explanation:

Because x is a positive integers it means that x could be any number that goes from zero to infinity.

The possible values of x such that 33/x remains a positive integer in ascending order are 1,3,11 and 33.

An integer is a whole number irrespective of the sign that the integer is all whole numbers that are going from 0 to infinite or 0 to minus infinite.

Integer ; ....-2 , -1 , 0 , 1 , 2 , .....

Given the expression, 33/x

Now positive integers are whole numbers ( 1,2,3,...)

To 33/x be the whole number and x is also a positive integer.

33/1 = 33 (1,3 Positive integer)

33/3 = 11 (3,11 Positive integer)

33/11 = 3 (11,3 Positive integer)

33/33 = 1 (33,1 Positive integer)

Hence "The possible values of x such that 33/x remains a positive integer in ascending order are 1,3,11 and 33".

Given:

The expression is

[tex]3(2x-4)-4x[/tex]

To find:

The simplified form of the given expression by using the distributive property and combining like terms.

Solution:

We have,

[tex]3(2x-4)-4x[/tex]

Using the distributive property, we get

[tex]=3(2x)+3(-4)-4x[/tex]

[tex]=6x-12-4x[/tex]

On combining like terms, we get

[tex]=(6x-4x)-12[/tex]

[tex]=2x-12[/tex]

Therefore, the simplified form of the given expression is [tex]2x-12[/tex].

Answer:

The factors are: (x - 8) and (x + 7)

Step-by-step explanation:

Given

[tex]x^2 - x - 56 = 0[/tex] -- the right equation

Required

Select the factors of the equation

[tex]x^2 - x - 56 = 0[/tex]

Expand the equation

[tex]x^2 + 7x - 8x - 56 = 0[/tex]

Factorize:

[tex]x(x+7)-8(x+7) =0[/tex]

Factor out x + 7

[tex](x-8)(x+7) =0[/tex]

Hence, the factors are: (x - 8) and (x + 7)

Answer:

The measure of angle 6 is 72.

The measure of angle 7 is 108.

Step-by-step explanation:

Corresponding angles are equal. So angle 1, 3, 5 and 7 are all equal.

If you look at angle 1 and 2, they are adjacent angles, so together they add up to 180. So if you subtract 108 from 180 you get 72... and we already established that all corresponding angles are equal, so if angle 2 is 72 degrees, we can conclude that angle 6 is as well.

Answer:

False

Step-by-step explanation:

It's actually C=πd d is diameter or C=πr^2

Answer:

True

Step-by-step explanation: Calculate circumference from area

We are given the area, and by substitution we know that 13π = πr2. We divide out the π and are left with 13 = r2. We take the square root of r to find that r = √13. We find the circumference of the circle with the formula C = 2πr.

Answer:

we have the expression as;

1/sin u cos u

Step-by-step explanation:

tan u = sin u/cos u

cot u = cos u/sin u

Thus;

sin u/cos u + cos u/sin u

The lcm is sin u cos u

Thus, we have that;

(sin^2 u + cos^2 u)/sin u cos u

But ; sin^2 u + cos^2 u = 1

so we have ;

1/sin u cos u

The requested trigonometric expression in terms of sine and cosine is;

[tex]f(u) = \frac{1}{ \frac{sinu}{cosu} + \frac{cosu}{sinu} } [/tex]

We must remember,

Therefore we have;

sin(u)/cos(u) + cos(u)/sin(u) = 1/f(u)

By Cross-product; we have;

[tex]f(u) = \frac{1}{ \frac{sinu}{cosu} + \frac{cosu}{sinu} } [/tex]

Therefore, the required function, f(u) in terms of sin u and cos u is as represented above.
