Step-by-step explanation:

[tex] {x}^{2} = {16}^{2} + {12}^{2} [/tex]

[tex] { x}^{2} = 256 + 144[/tex]

[tex] {x}^{2} = 400[/tex]

[tex]x = 20[/tex]

Answer:

[tex](x-5)^{2}[/tex]

Step-by-step explanation:

[tex]ax^{2} + bx + c[/tex]

Take the value for b, divide it by 2 and square it to get the value for c.

In this case, b = -10.

- 10 ÷ 2 = -5

-5^2 = 25

So x^2 - 10x +25 is your quadratic equation which is equal to

[tex](x-5)^{2}[/tex]

Answer:

true

Step-by-step explanation:

y = ab^x

the coordinates of the point are x and y values.

so, we can express "a" by these values :

k = ab^h

a = k/(b^h) = k × b^-h

now we use this identity in the original equation and get

y = k × b^-h × b^x = k×b^(x-h)

and that is exactly the same as the proposed form.

Displacement is the shortest distance from the initial to the final position. So to calculate you do 15 - (3/4 of 15) = 3.75

Answer:

here you go

Step-by-step explanation:

First: work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number.

Then: divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number × 100.

Answer:

Step-by-step explanation:

(I assumed that this was a rectangular prism based on the dimensions given, but do correct me if I assumed incorrectly.)

The formula for finding the volume of a rectangular prism is: [tex]V=w*h*l[/tex]

In this case, we already know that the volume of the prism is 24, so we can plug 24 in for V:

[tex]24=w*h*l[/tex]

We also already know the height and the length because they gave it to us, so we can plug it in as follows:

[tex]24=w*2*4[/tex]

Then we can multiply 2 and 4 on the right side:

[tex]24=w*8[/tex]

Then, to get the w alone, we can divide by 8 on both sides:

[tex]3=w[/tex]

Now that gives us that the width of the rectangular prism is 3ft.

CS = x, and since AB = BC = CD = DA = 1cm -> SD = 1 - x

We see that angle DSP = angle APQ (because they simultaneously equal to 90 when added angle DPS)

So, triangle DSP = triangle APQ (equal hypotenuse - square side and equal angle.)

Similarly, we can prove triangle SCE and QBE in the same way

So, all 4 of the triangles are equal to each other.

-> SD = CE = BQ = AP = 1-x

Calculate the area of 4 triangles : [ x(1-x) : 2 ] x 4 = x(1-x) x 2

Area (PQRS) = 1 - [ x(1-x)] x 2 = 1 - 2x + 2x(squared) = [tex]2x^{2} -2x + 1[/tex]

ii) Half area of PQRS = [tex]x^{2} -x+1[/tex]

= [tex]x^{2} -\frac{1}{2} x-\frac{1}{2} x + \frac{1}{2} = x(x-\frac{1}{2} )- \frac{1}{2}(x-\frac{1}{2} ) + \frac{1}{4} = (x-\frac{1}{2})^{2} + \frac{1}{4}[/tex]

We have : [tex](x-\frac{1}{2}) ^{2}[/tex]

has the smallest value of 0 -> The smallest half value of PQRS = 1/4 -> The smallest value of PQRS = 1/2

Step-by-step explanation:

Addison needs to cut $45 from Food/Clothes and $41 from Entertainment, to pay the revised monthly payment.

It is given that

Addison has a balance of $3,450 on her credit card.

APR = 18%

Current monthly payment = $86.25

She wants to choose a monthly payment for 24 months.

So for 24 months,

A revised monthly payment using formula,

[tex]M = \frac{P.\frac{R}{12}. (1+\frac{R}{12} )^N }{(1+\frac{R}{12})N -1}[/tex]

R = 0.18

P = 3450

N = 24

Revised montly payment M = $172.24

Current monthly payment = $86.25

Difference = $86

So, she needs to cut the expenses by  $86

If she cut $45 from Food/Clothes and $41 from Entertainment, she can easily pay the revised monthly payment.

Therefore, Addison needs to cut $45 from Food/Clothes and $41 from Entertainment, to pay the revised monthly payment.

Work Shown:

If cos(A) = sin(B), then A+B = 90, where A & B are both acute angles in degree form.

In this case, A = 52, so,

A+B = 90

B = 90-A

B = 90-52

B = 38

Telling us that

cos(A) = cos(52) = 0.6157

sin(B) = sin(38) = 0.6157

cos(52) = sin(38)

Answer:

{7, 5, 2, 0}

Step-by-step explanation:

The domain is essentially all the [tex]x[/tex] values of the function, where the range is the value of [tex]h(x)[/tex].

So in order to solve this we simply plug in each number into the equation and get:

[tex]h(x)=|-2-5| = |-7|=7[/tex]

[tex]h(x)=|0-5| = |-5|=5[/tex]

[tex]h(x)=|3-5| = |-2|=2[/tex]

[tex]h(x)=|5-5|=|0|=0[/tex]

Answer:

Let us divide the circle into 4 equal parts because they have told that 1/4 th part so there are 4 equal parts because,fractions represent equal parts of a whole or a collection.

Let us take a circle with centre 'O'

Now, the 1/4th part of circle is a sector with angle 90° & radius 3.5cm

We can find the area of sector in 2 methods

Method 1 :

Formula :

Here , r is radius & θ is the angle in sector where θ is measured in degrees

Hence , area of sector = 9.6cm²

Method 2 :

Formula:

Here , r is radius & θ is angle in sector where θ is measured in radians

First we have to convert 90° into radians

We know that π radians = 180°

90 ° = π/2 radians

Substituting

Hence , area of sector = 9.6 cm²

Answer:

3-2r + 1 - 13

Step-by-step explanation:

3-2r + 1 - 13

Answers:

=============================================

Work Shown:

3 < 2x+1 < 13

3-1 < 2x+1-1 < 13-1 .... subtract 1 from all sides

2 < 2x < 12

2/2 < 2x/2 < 12/2 ... divide both sides by 2

1 < x < 6

The value of x is between 1 and 6, excluding both endpoints.

Since we exclude both endpoints, the graph will have open holes at 1 and 6 on the number line. The shading is between the open holes. The graph is below.

Converting 1 < x <6 to interval notation leads to (1, 6)

The curved parenthesis in interval notation indicate "exclude the endpoint".
