Answer:

14 mm

Step-by-step explanation:

Just as the little side is 1/4 of the larger side , so is the perimeter

1/4 * 56 = 14 mm

Answer:

20 + 6n > 75(the sign has an underline)

To determine how many miles Kayla needs to hike each week for the next 6 weeks to reach her goal of at least 75 miles, we can subtract the miles she has already hiked from her target goal and divide it by the number of weeks remaining.

Target goal - Miles already hiked = Miles remaining

75 miles - 20 miles = 55 miles remaining

Now, we divide the remaining miles by the number of weeks:

55 miles / 6 weeks = 9.17 miles per week (approximately)

Therefore, Kayla needs to hike approximately 9.17 miles each week for the next 6 weeks in order to reach her goal of at least 75 miles.

Answer:

x = 35.5

Step-by-step explanation:

assuming all sides are equal (a square),

4x = 142

4x / 4 = 142 / 4

x = 35.5

Answer:

9

Step-by-step explanation:

For the equation x² - 6x = 5 the coefficient of the term x is -6

(-6/2)2 = 9

The given equation can be written as

x2 - 6x + 9 = 5 + 9

x2 - 6x + 9 = 14

We can write it as

(x - 3)2 = 14

Take square root on both sides.

|x - 3| = √14

We get

x = 3 + √14

In other case,

- x + 3 = √14

x = 3 - √14

Therefore, 9 should be added to both sides of the equation to complete the square (x2 - 6x = 5).

What number should be added to both sides of the equation to complete the square (x2 - 6x = 5)?

Summary:

The number that should be added to both sides of the equation to complete the square (x2 - 6x = 5) is 9.

Answer:

-40%

Step-by-step explanation:

NV = new value

OV = old value

percent change = (NV - OV)/(OV) × 100%

percent change = (30 - 50)/(50) × 100%

percent change = -20/50 × 100%

percent change = -40%

Vol_prism = 48 (all answers should have the units cm^3)

Vol_pyramid = 25

Vol_cyl = 37.68

Vol_cone = 12.56

Vol_sphere = 113.04

Step-by-step explanation:

This was a very compact problem (5 problems!) You read the chart top to bottom and each column is a different problem.

Vol of a prism:

V = l×w×h = 4×4×3

= 48 cm^3

Vol of a pyramid:

V = 1/3Base•h

= 1/3 (5×5)•3

= 25 cm^3

Vol of a cylinder:

V = pi•r^2•h

= pi•2^2•3

= pi•4•3

= 12pi = 12(3.14)

= 37.68 cm^3

Vol of cone:

= 1/3pi•r^2•h

= 1/3pi•2^2•3

= 4pi = 4(3.14)

= 12.56 cm^3

Vol of a sphere:

V = 4/3pi•r^3

= 4/3 pi•3^3

= 4/3 pi•27

= 36pi = 36(3.14)

= 113.04 cm^3

Pheewwwww! That was a lot! Hopefully you are just reviewing all your volume formulas. Hope this helps!

Answer:

x = 1/20 y^2

Step-by-step explanation:

This is a rightward opening  (sideways ) parabola

Directrix = x = -5

Distance formula form point x,y  to directrix and focus are equal:  

(x - -5)^2 = (x-5)^2 + y^2

x^2 + 10x + 25 = x^2 - 10x  + 25 + y^2

20x = y^2

x = 1/20 y^2

The function f(x) =  x² + 12x is a quadratic function, and the vertex of the function is (-6,-36)

The equation of the function is given as:

f(x) =  x² + 12x

Differentiate the function

f'(x) = 2x + 12

Set the function to 0

2x + 12 = 0

Add -12 to both sides

2x = -12

Divide both sides by 2

x = -6

Set x = -6 in the function f(x)

f(-6) =  (-6)² + 12(-6)

Evaluate

f(-6) =  -36

Hence, the vertex of the function is (-6,-36)

Answer:

Ray, you need the slope-intercept formula  y=mx+b

Step-by-step explanation:

Next you'll need 2 points,  any points are fine.  Just find two easy ones along the line.  I'll just pick  Point 1  as P1 = ( 0,4)  and point 2 as P2 = (4,0) because they are easy to work with.

next use

point P1 (0,4)  in the form (x1,y1)

point P2(4,0)  in the form (x2,y2)

slope = m

m = (y2-y1) / (x2-x1)

m = (0-4) / (4-0)

m = -4 / 4

m = -1

now use the point slope with one of the points,  to find the slope-intercept form.

y - y1 = m(x -x1)

y - 4 =  -1(x-0)

y -4 = -x

y = -x + 4

note:

y = mx +b

y = (-1)x + b    is the form.   see?

Answer:

y = mx + b

m = slope

b = intercept

From the graphic:

(x₁, y₁) = (0, 4)

(x₂, y₂) = (4, 0)

[tex]\frac{y-y_{1} }{y_{2} -y_{1} } =\frac{x-x_{1} }{x_{2} -x_{1} } \\\\\frac{y-4 }{0 -4} =\frac{x-0 }{4 -0 } \\\\\frac{y-4}{-4} =\frac{x}{4} \\\\(y-4)4=-4x\\\\y-4=-x\\y=-x+4\\[/tex]

The radius of Convergence  for the function [tex]\frac{\[(-1)^{n} \; x^{n} }{\sqrt[3]{n} }[/tex]  is 1.

The radius of the largest disk at the center of the series in which the series converges.

Perform the ratio test for absolute convergence, which says

if    [tex]\lim_{n \to \infty} \frac{a_{n}}{a_{n+1}}[/tex]   =L

Then,

1) if L<1, the series is absolutely convergent

2) If L>1, the series is divergent

3) If L= 1, apply a different test.

Now, Applying test

[tex]a_{n+1}[/tex] =[tex]\frac{(-1)^{{n+1} } \; x^{n+1}}{\sqrt[3]{n+1} }[/tex]

So,

[tex]\lim_{n \to \infty} \frac{a_{n+1}}{a_{n}}[/tex]  = [tex]\lim_{n \to \infty}|\frac{ (-1)^{{n+1} } \; x^{n+1}/\sqrt[3]{n+1} }{ (-1)^{n} \; x^{n} /\sqrt[3]{n} } |[/tex]

                     = [tex]\lim_{n \to \infty}|\frac{ (-1)^{{n+1} } \; x^{n+1}\sqrt[3]{n}}{ (-1)^{n} \; x^{n} \sqrt[3]{n+1} } |[/tex]

                     = [tex]\lim_{n \to \infty}|\frac{ (-1) \; x^{n}\sqrt[3]{n}}{ \sqrt[3]{n+1} } |[/tex]

                    = [tex]\lim_{n \to \infty}\sqrt[3]{\frac{1}{1+\frac{1}{n}} } } |x|[/tex]

Applying the limit n→∞,

= 1 x |x|

= |x|

By ratio test, the given series will be convergent if |x|< 1.

So, the radius of Convergence = 1

The volume is calculated using:

V = bh

Make h the subject

h = V/b

Substitute V = 2850

Answer:

4 units

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

given A = 14 and h = 7 , then

[tex]\frac{1}{2}[/tex] × 7b = 14 ( multiply both sides by 2 to clear the fraction )

7b = 28 ( divide both sides by 7 )

b = 4 units

Answer:

67.38 degrees

Step-by-step explanation:

this is a right triangle so we can use sohcahtoa

we want to calculate angle A

we know the side opposite to A as well as the hypotenuse. 13 is the hypotenuse because it is opposite the right angle

thus, sin(A) = opposite/hypotenuse = 12/13

arcsin(12/13) = A ≈ 67.38 degrees
