Half of a number increased by seventeen is 8

Answer:

9.067cm

Step-by-step explanation:

x--- amount by which the length is reduced

area=(18-x)(15)=134

(18-x)=134/15

x=18-(134/15)

x= 9.067cm

Answer:

9(11x+1)

Step-by-step explanation:

99x + 9

The greatest common factor is 9 so put 9 outside of parenthesis

9(11x+9)

Answer:

9(11x+1)

Step-by-step explanation:

We can see that these two values in the equation can be factored by 9 so divide both by 9

99/9= 11

9/9= 1

Rewrite expression by inputting the numbers in parenthesis while keeping the 9 "outside"

9(11x+1)

Many authors do not recognize three points on a line as forming a triangle. This is because its area is zero. (The "base" is the length of the line segment; the "height" is the width of the line (zero).)

The number of different ways there for him to order the different steps of his morning routine will be 5040.

The arrangement of the different things or numbers in a number of ways is called the combination.

A combination in mathematics is a choice made from a group of separate elements where the order of the selection is irrelevant.

It is given that every morning before going to class, Knut takes a shower, checks his email, does 100 pushups, and makes a milk, egg, and tuna smoothie. Knut always takes his shower last.

The arrangement will be calculated as below:-

The number of the activities is 7.

The number of ways = 7!

The number of ways = ( 7x 6 x 5 x 4 x 3 x  2 )

The number of ways = ( 5040 ).

Therefore, the number of different ways there for him to order the different steps of his morning routine will be 5040.

Step-by-step explanation:

That point is ...

  A + (7/10)(B -A)

  = (-3, -7) +(7/10)(11 -(-3), 4 -(-7)) = (-3, -7) +7/10(14, 11)

Answer:  [tex](x-9)^2 + (y-12)^2 = 225\\\\[/tex]

This is the same as writing (x-9)^2 + (x-12)^2 = 225

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

Explanation:

Any circle equation fits the template of [tex](x-h)^2 + (y-k)^2 = r^2\\\\[/tex]

The center is (9,12) which tells us the values of h and k in that exact order.

h = 9

k = 12

To find the radius r, we need to find the distance from the center (9,12) to a point on the circle. The only point we know on the circle is the origin (0,0).

Apply the distance formula to find the distance from (9,12) to (0,0)

[tex]d = \sqrt{ (x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{ (9-0)^2+(12-0)^2}\\\\d = \sqrt{ (9)^2+(12)^2}\\\\d = \sqrt{ 81+144}\\\\d = \sqrt{ 225}\\\\d = 15\\\\[/tex]

The distance from (9,12) to (0,0) is 15 units. Therefore, r = 15

An alternative to finding this r value is to apply the pythagorean theorem. The distance formula is effectively a modified version of the pythagorean theorem.

---------------------

Since h = 9, k = 12 and r = 15, we can then say:

[tex](x-h)^2 + (y-k)^2 = r^2\\\\(x-9)^2 + (y-12)^2 = 15^2\\\\(x-9)^2 + (y-12)^2 = 225\\\\[/tex]

which is the equation of this circle.

D: 1,130 cm³

Step-by-step explanation:

You need the volume of  a cylinder.

V = πr²h

V = 3.14159 * (6 cm)² * 10 cm

V = 3.14159 * 36 cm² * 10 cm

V = 1130.97 cm³

Answer: D: 1,130 cm³

Answer:

The choose D. 1130 cm³

v = r² pi/ h

v = (6)² × 3.14 × 10

v = 1130.4

v = 1130

Answer:

Step-by-step explanation:

a) If we let B, L, F represent the elevations of the basement, lobby, and first floor, respectively, then we have ...

  B = -22

  L = 0

  F = 18

Your inequality could be either of ...

  B < L

  -22 < 0

__

b. We're not sure exactly the form you're looking for. Use whichever absolute value statement is appropriate to your needs.

  distance = |B -L| = |-22 -0| = |-22| = 22

__

c. The distance from the lobby to the first floor is |18 -0| = 18.

The distance from the lobby to the basement is |-22-0| = 22.

The distance 22 is greater than the distance 18, so the distance to the basement is greater.

_____

Additional comment

The difficulty with this question is not figuring out whether -22 is farther from 0 than is +18. The difficulty is in figuring out the form of the answer that is expected. Without looking at your curriculum materials, we cannot even make an appropriate guess.

Answer:

DAC=18(corresponding angles)

EAD= 162 degrees

Step-by-step explanation:

DAC=18(corresponding angles)

EAD=180-18(angles on a straight line)

EAD= 162 degrees

Answer:

Here, we have,

<HBA=18°

<DAC=?

<EAD=?

Now,

i)<DAC=<HBA=18°[being corresponding angle]

ii)<EAD+<DAC=180°[being straight angle]

or, <EAD+18°=180°

or, <EAD=180°-18°

or, <EAD=162°

Thus, <DAC=18° and<EAD=162°.

6647 is a whole. For you to know the relationship between the 6s in this number write their values. The value of the first 6 is 6000. The value of the second 6 is 600.

There are four parts of a circle, so you have to find out the area of the circle:-

10 cm=Radius

[tex]10^{2}[/tex]=100

[tex]\pi[/tex]=3.14

3.14*100=314 [tex]cm^{2}[/tex]

Now, find the area of the square box:-

Since half the side of the square is 10 cm, the total length of one side is 2*10 which is 20 cm.

Area=S*S

=20*20=400 [tex]cm^{2}[/tex]

Now subtract the area of the box from the area of the square:-

400-314= 86 [tex]cm^{2}[/tex]

That is the area of the shaded part.

A percentage is a way to describe a part of a whole. The value of x is 5,000.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that 8.4% of x is 420. Therefore, we can write the given statement in the form of an equation as,

8.4% of x = 420

8.4% × x = 420

(8.4/100) × x = 420

x = (420 × 100)/8.4

x = 5,000

Hence, the value of x is 5,000.

Use reduction of order. Given a solution [tex]y_1(x) = x^2[/tex], look for a second solution of the form [tex]y_2(x) = y_1(x)v(x)[/tex].

Compute the first two derivatives of [tex]y_2(x)[/tex]:

[tex]y_2 = x^2v \\\\ {y_2}' = x^2v' + 2xv \\\\ {y_2}'' = x^2v''+4xv' + 2v[/tex]

Substitute them into the ODE:

[tex]x^4 (x^2v'' + 4xv' + 2v) + x^3 (x^2v' + 2xv) - 4x^2 (x^2v) = 1 \\\\ x^6v'' + 5x^5v' = 1[/tex]

Now substitute [tex]w(x) = v'(x)[/tex] and you end up with a linear ODE:

[tex]x^6w'+5x^5w=1[/tex]

Multiply through both sides by [tex]\frac1x[/tex] (if you're familiar with the integrating factor method, this is it):

[tex]x^5w'+5x^4w = \dfrac1x[/tex]

Bear in mind that in order to do this, we require [tex]x\neq0[/tex]. Just to avoid having to deal with absolute values later, let's further assume [tex]x>0[/tex].

Notice that the left side is the derivative of a product,

[tex]\left(x^5w\right)' = \dfrac1x[/tex]

Integrate both sides with respect to [tex]x[/tex] :

[tex]x^5w = \displaystyle \int\frac{\mathrm dx}x \\\\ x^5w = \ln(x) + C_1[/tex]

Solve for [tex]w(x)[/tex] :

[tex]w = \dfrac{\ln(x)+C_1}{x^5}[/tex]

Solve for [tex]v(x)[/tex] by integrating both sides:

[tex]v = \displaystyle \int \frac{\ln(x)+C_1}{x^5} \,\mathrm dx[/tex]

Integrate by parts:

[tex]\displaystyle f = \ln(x) + C_1 \implies \mathrm df = \frac{\mathrm dx}x \\\\ \mathrm dg = \frac{\mathrm dx}{x^5} \implies g = -\frac1{4x^4} \\\\ \implies v = -\frac{\ln(x)+C_1}{4x^4} + \frac14 \int \frac{\mathrm dx}{x^5} \\\\ v = -\frac{\ln(x)+C_1}{4x^4} - \frac1{16x^4} + C_2 \\\\ v = -\frac{4\ln(x)+C_1}{16x^4}+C_2[/tex]

Solve for [tex]y_2(x)[/tex] :

[tex]\displaystyle \frac{y_2}{x^2} = -\frac{4\ln(x)+C_1}{16x^4}+C_2 \\\\ y_2 = -\frac{4\ln(x)+C_1}{16x^2} + C_2x^2[/tex]

But since [tex]y_1(x)=x^2[/tex] is already accounted for, the second solution is just

[tex]\displaystyle y_2 = -\frac{4\ln(x)+C_1}{16x^2}[/tex]

Still, the general solution would be

[tex]\displaystyle \boxed{y(x) = -\frac{4\ln(x)+C_1}{16x^2} + C_2x^2}[/tex]
