Answer:

10p-40 = 10(p-4) this is the answer of this question

Step-by-step explanation:

So basically you're going to start with your (expected value - observed value) squared

(O-E)²

You're then gonna divide that by your expected value that you just used

(O-E)²/E

Answer:

5955.08

Step-by-step explanation:

First year: 5000×(6÷100)=300

Second year : 5300×(6÷100)=318

Third year : 5618×(6/100)=337.08

And = 5955.08

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.

Answer:

Step-by-step explanation:

This expression has two terms.  They have nothing in common, so we cannot factor.  We could write it at 17x - z.

Answer:

x = 18.7

Step-by-step explanation:

Gerald's answer is almost correct.  

He just needs to switch the 14 and the x.

it should be

24/x = 18/14

solve for x by cross multiplication

18x = (24)(14)

18x = 336

x = 18.7

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

Vertical Shift => up 4

Equation: f(x) =  6cos(2x) + 4

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.

Answer:

The food will last for 10 days

Step-by-step explanation:

Proportions

The amount of food the farmer needs to feed his animals is proportional to the number of animals and to the number of days they are fed.

This can be written as:

Food=k*N*D

Where k is a constant, N is the number of animals and D is the number of days.

We know that the farmer has enough food to feed N=50 animals for D=15 days, thus:

Food=k*50*15=750k

If the same amount of food is used for 50+25=75 animals, then:

750k=k*75*D

Simplifying:

750=75*D

Dividing by 75:

D=10

The food will last for 10 days

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:

26m

Step-by-step explanation:

The diagonals of a parallelogram bisects each other. Hence the length of UV is equal to the length of VS

UV = VS

x+3 = 2x-7

x-2x = -7-3

-x = -10

x = 10

Get SU

SU = UV+VS

SU = x+3+2x-7

SU = 3x-4

Substitute x=10 into the expression

SU = 3(10)-4

SU = 30-4

SU = 26m

Length of SU is 26m
