Answer:

<u>31.8</u>

Step-by-step explanation:

I will assume that

"-6.1(-4.1) +6.8="

means (-6.1)*(-4.1) +6.8=

(-6.1)*(-4.1) = 25

25 + 6.8 = <u>31.8</u>

Find the equation of the linear function passing through (2,3) and (5,12)
Elis [28]

y = 3x - 3 is the equation of the linear function passing through (2, 3) and (5, 12)

<em><u>Solution:</u></em>

Given that we have to find the equation of linear function passing through (2, 3) and (5, 12)

The formula y = mx + b is said to be a linear function

Where "m" is the slope of line and "b" is the y - intercept

Let us first find the slope of line

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

\text {Here } x_{1}=2 ; y_{1}=3 ; x_{2}=5 ; y_{2}=12

Substituting values we get,

m=\frac{12-3}{5-2}=\frac{9}{3}=3

Thus slope of line is m = 3

To find the y - intercept, substitute m = 3 and (x, y) = (2, 3) in y = mx + b

3 = 3(2) + b

3 = 6 + b

b = 3 - 6

b = -3

Thus the required equation of linear function is:

Substitute m = 3 and b = -3 in formula

y = mx + b

y = 3x - 3

Thus the equation of linear function is found

the area of a rectangle is 45 x^8 x^9 square yards. And the length is of the rectangle is 5 x^3 x^4 yards. Which expression repr
swat32

Answer:

width \: of \: the \: rectangle \\  =  \frac{area \: of \: rectangle}{length \: of \: rectangle}  \\  \\  =  \frac{45 {x}^{8} \times  {x}^{9}  }{5 {x}^{3} \times  {x}^{4} } \\  \\  =  \frac{45 {x}^{8 + 9} }{5 {x}^{3 + 4} }  \\   \\ =  \frac{45 {x}^{17} }{5 {x}^{7} }  \\   \\ =  9 {x}^{17 - 7}  \\ \\  =  9 {x}^{10}  \: yards \\  \\  \therefore \: width \: of \: the \: rectangle  \\  \:  \:  \:  \:  \:  \: = 9 {x}^{10}  \: yards  \\

F(x)=cos(x). Find the x-intercepts of f(x) on [0, 2).
balu736 [363]

The x-intercepts of the function where the function is given as y(x) = cos(x) are π/2 and 3π/2

<h3>What is the x-intercept of the function?</h3>

The x-intercept of the function is the point or points where the graph of the function crosses the x-axis i.e. the point where the function equals 0

<h3>How to find the x-intercepts of the function?</h3>

The function is given as

f(x) = cos(x)

And the interval is given as

[0, 2)

The above means that we determine the value of x when the function f(x) equals 0

So, we have

cos(x) = 0

The above equation can be solved graphically

See attachment for the graph of the function f(x) = cos(x)

In the interval [0, 2), the graph crosses the x-axis at points x = π/2 and 3π/2

Hence, the x-intercepts of the function where the function is given as y(x) = cos(x) are π/2 and 3π/2
