option ( c ) [tex]\huge\pink{1 \frac{2}{5} }[/tex]

step by step explanation -

well , the question asks us to find the difference between the two terms given as mixed fractions ~

tho it's not that difficult to simplify a problem in mixed fraction , but solving the problem by first converting it to an improper fraction reduces the risk of mistakes ! so let's do the question by that way ~

[tex]4 \frac{4}{5} - 3 \frac{2}{5} \\ \\ converting \: into \: improper \: fraction \: we \: get \\ \\ \implies \: \frac{5 \times 4 + 4}{5} \: \: - \: \: \frac{5 \times 3 + 2}{5} \\ \\ \implies \: \frac{24}{5} \: \: - \: \: \frac{17}{5} \\ \\ since \: the \: denominators \: are \: same \: we \: can \: simply \: subtract \: the \: terms \\ \\ \implies \: \frac{7}{5} [/tex]

we're done with our solution tho , but since the options given are in mixed fraction , so let's convert the improper fraction , obtained as the answer , into a mixed fraction !

[tex] \frac{7}{5} = 1 \frac{2}{5} \\ [/tex]

The true solution of the logarithmic equation [tex]\ln e^{\ln x} + \ln e^{\ln x^2} = 2\ln 8[/tex] will be 4.

What is a logarithm?

Logarithms are another way of writing exponent. A logarithm with a number base is equal to the other number. It is just the opposite of the exponent function.

The logarithmic equation is given as

[tex]\ln e^{\ln x} + \ln e^{\ln x^2} = 2\ln 8[/tex]

We know that the formula

[tex]\ln e = 1\\\\\ln b^a = a \ln b\\\\\ln a + \ln b= \ln a +b[/tex]

Then we have

[tex]\begin{aligned} \ln x \times \ln e + \ln x^2 \times \ln e = \ln 8^2\\\\\ln x + \ln x^2 = \ln 64\\\\\ln x*x^2 = \ln 64 \end{aligned}[/tex]

Then take antilog, then we get

[tex]\rm x^3 = 64\\\\x^3 = 4^3 \\\\x \ =4[/tex]

Step-by-step explanation:

then p(3) = 3

where you see x add 3

so 1/2(x-5)^2 + 14

1/2(3-5)^2 + 14

1/2(-2)^2 + 14

1/2 x 4 + 14

Step-by-step explanation:

comparing given equation with ax^2+bx+c;

a=1 b=-16 c=39

now,

x coordinate of vertex = -b/2a

= 16/2*1

= 8

again,

y coordinate of vertex = (8)^2-16(8)+39

=-25

Therefore, the turning point is (8,-25).

The length of a rectangular garden is 2 m greater than the width. The area is 80 m^2. Find the dimensions of the garden.

The width of the garden is ___m.
The length of the garden is ___m.

Answers

Answer:

Length of rectangle = 10 mWidth of the Rectangle = 8 m

Step-by-step explanation:

Given :-

Length of a Rectangular garden is 2m greater than the width .Area of garden = 80 m²

To Find :-

Dimensions of the garden

Solution :-

Let's assume:

Width of the rectangle = xLength of the rectangle = x + 2

We know that,

Area of rectangle = Length × Width

↠ (x)(x + 2) = 80

↠ x² + 2x - 80 = 0

↠ x² + 10x - 8x - 80 = 0

↠ x(x +10) -8 (x + 10) = 0

↠ (x-8) (x + 10) = 0

↠ x = 8 or -10

↠ x = 8

Hence,

Width of the rectangle = x = 8 mLength of the rectangle = x + 2 = 10 m

Answer:

Given:-

Length of rectangular garden is 2m longer than its widthArea of Rectangular garden is 80m²

To Find :-

Dimensions of Rectangular garden

Solution:-

Let the width be x and length be x + 2

According to the question ,

Area = 80m²

putting the known values ,

(X)(X+2) = 80m

x² +2x - 80= 0

x² +10x-8x -80m= 0

x(x + 10) - 8(x+10) = 0

(x-8) = 0 ; (x+10) = 0

X = 8 ; X = -10

As dimensions can not be negative so , X = 8

Length = X + 2 ; 10 m

Width = X ; 8 m

a 2014 mustang originally costs $25000.00 and depreciates at a rate of 8% per year. What is the cost of the car after 7 years?

Answers

$11,000 will bet the cost in 7 years

Given:

Original cost: $25,000

Depreciation rate: 8%

Term: 7 years

Formula for Depreciation:

A = C ( 1 - ( r ) (t) )

A = Future Value

C = Original Cost

r = rate

t = term

Solution:

Substitute the given values to the formula for depreciation.

A = $25,000( 1 - ( 0.08)(7))

A = $25,000( 1 - .56 )

A = $25,000(0.44 )

A = $11,000

So, the length of the side adjacent to angle β is approximately 17.15 cm. triangle Therefore, the closest option is 16.7 cm.

What is a triangle?

A triangle is a closed, double-symmetrical shape composed of three line segments known as sides that intersect at three places known as vertices. Triangles are distinguished by their sides and angles. Triangles can be equilateral (all factions equal), isosceles, or scalene based on their sides. Triangles are classified as acute (all angles are fewer than 90 degrees), good (one angle is equal to 90 degrees), or orbicular (all angles are higher than 90 degrees) (all angles greater than 90 degrees). The region of a triangle can be calculated using the formula A = (1/2)bh, where an is the neighbourhood, b is the triangle's base, and h is the triangle's height.

sin(β) = opposite/hypotenuse

[tex]hypotenuse^2 = adjacent^2 + opposite^2\\17.5^2 = adjacent^2 + opposite^2\\306.25 = adjacent^2 + opposite^2\\[/tex]

opposite = sin(β) x hypotenuse = 0.292 x 17.5 = 5.095 cm

[tex]306.25 = adjacent^2 + 5.095^2\\306.25 - 5.095^2 = adjacent^2\\294.81 = adjacent^2\\[/tex]

√294.81 = adjacent

So, the length of the side adjacent to angle β is approximately 17.15 cm. Therefore, the closest option is 16.7 cm.

( Find the Mean Absolute Deviation and the Mean with an explanation )
How many siblings do the students in my math class have?
3,2,2,5,4,1,3,4,1,0,3,2,1,1,6,3

Answers

The mean of the data is 1.31, while the mean absolute deviation is 2.56.

What is the Mean Absolute Deviation?

The mean is the average of a data set, while the mean absolute deviation is the average distance of the each data point from the mean.

Given the data:

3,2,2,5,4,1,3,4,1,0,3,2,1,1,6,3

Find the Mean:

Mean = (3 + 2 + 2 + 5 + 4 + 1 + 3 + 4 + 1 + 0 + 3 + 2 + 1 + 1 + 6 + 3)/16 = 41/16 Mean = 2.5625

Find the Mean Absolute Deviation:

Mean abosolute deviation = (3 - 2.5625) + (2 - 2.5625) + (2 - 2.5625) + (5 - 2.5625) + (4 - 2.5625) + (1 - 2.5625) + (3 - 2.5625) + (4 - 2.5625) + (1 - 2.5625) + (0 - 2.5625) + (3 - 2.5625) + (2 - 2.5625) + (1 - 2.5625) + (1 - 2.5625) + (6 - 2.5625) + (3 - 2.5625) / 16

Mean abosolute deviation = 21/16 = 1.3125

Therefore, the mean of the data is 1.31, while the mean absolute deviation is 2.56.

Rounded to the nearest tenth of a centimeter, what is the length of arc lmn? 7.9 cm 10.2 cm 12.6 cm 14.2 cm

Answers

The length of arc LMN is the number of units on the arc

The length of arc LMN is 14.2 cm

How to calculate the length of the arc?

The given parameters are:

Arc LM = 6.3 cmRadius, r = 6 cmAngle MON = 75 degrees

Start by calculating the length of arc MN using:

[tex]MN = \frac{\theta}{360} * 2\pi r[/tex]

So, we have:

[tex]MN = \frac{75}{360} * 2 * 3.14 * 6[/tex]

Evaluate the product

MN = 7.85

The length of arc LMN is then calculated using:

LMN = LM + MN

This gives

LMN = 6.3 + 7.85

Evaluate the sum

LMN = 14.15

Approximate

LMN = 14.2

Hence, the length of arc LMN is 14.2 cm
