A triangle has an area of 14 square units. Its height is 7 units. What is the length of its base

Answers

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: 4 units

Step-by-Step Explanation:

Let ‘x’ be the Base of the Triangle.

Area = 14 square units
Height = 7 units

Therefore,
= Area = 1/2 * Base * Height
= 1/2 * x * 7 = 14
= x/2 * 7 = 14
= 7x/2 = 14
= 7x = 14 * 2 = 28
=> x = 28/7 = 4

Therefore, Base = x = 4 units

A regular pentagonal prism has a volume of 2,850 cubic millimeters. What is the height of the prism

Answers

The expression that represents the height of the prism is 2850/b where b is the base area

How to determine the height?

The given parameter is:

Volume = 2850

Let the height of the prism be h, and the base area be b.

The volume is calculated using:

V = bh

Make h the subject

h = V/b

Substitute V = 2850

h = 2850/b

Hence, the expression that represents the height of the prism is 2850/b

Please help. What is the equation of the line in slope-intercept form?​

Answers

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]

focus: (5, 0)

Answers

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

(−1)^nx^n/ cubicroot n find the radius of convergence

Answers

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

What is radius of convergence?

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

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

Solve by using substitution. Express your answer as an ordered pair. 2x+y=-5 y=x+4

Answers

Answer: (-3, 1)

Step-by-Step Explanation:

=> 2x + y = -5 (Eq. 1)
=> y = x + 4 (Eq. 2)

Substitute value of ‘y’ from Eq. 2 in 1 :-

2x + y = -5
2x + (x + 4) = -5
2x + x + 4 = -5
3x + 4 = -5
3x = -5 - 4
3x = -9
x = -9/3
=> x = -3

Therefore, x = -3

Substitute value of ‘x’ in Eq. 2 :-

y = x + 4
y = (-3) + 4
=> y = 1

Therefore, y = 1

This Solution can be written in the ordered form as (-3, 1)

Problem 2
Kayla has a goal to hike at least 75 miles. She has
already hiked 20 miles.
She plans to hike n miles each week for the next 6
weeks.
Which inequality describes the nuinber of miles Kayla
should hike each week to meet her goal?
20 + 6n < 75
20 - 6n < 75
20 + 6n > 75
20 - 6n > 75
( the signs are supposed to have the line underneath it )

Answers

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.

Let x^2+ 6x = 5
What values make an equivalent number sentence after completing the square?
Enter your answers in the boxes.
x² +6x+ ____=_____

Answers

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.

What is the vertex of the function f(x) = x2 12x? (–6, –36) (–6, 0) (6, 0) (6, –36)

Answers

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

How to determine the vertex of the function?

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)

area of a triangle = 1/2 × base length × height

base length = 12 and height = 12

area = 1/2 × 144
