Consider the two expressions. Expression 1: -4(9x-2)+3
Expression 2: -36x+k
What value of k will make the two expressions equivalent?​

Answers

Answer 1

Answer:

11

Step-by-step explanation:

first, distribute the negative four in Expression 1: -36x+8+3

next, set that equal to Expression 2: -36x+11 = -36x+k

finally, add 36x to both sides: 11 = k

Initial amount of investment is $500, each year the investment grows by 6%, and after ten years the investment becomes $800.

How I did this, the initial investment is y intercept AKA the value of y at x=0, to get percentile growth, I did year 0/ year 1 and got 0.94 or 94%, but you have to subtract that from 1 which gives you 0.06 or 6%, and to find value of investment after 10 years, I first did 6% growth per year multiplied by 10 years which gives you 60%, then I multiplied 500(1.6) and got 800. Hope this helped!

Answers

Answer:

35.09

Step-by-step explanation:

From the question given above, the following data were:

Opposite = 12

Hypothenus = X

Angle θ = 20 °

The value of x can be obtained by using sine ratio as illustrated below:

Sine θ = Opposite / Hypothenus

Sine 20 = 12 / X

0.342 = 12 / X

Cross multiply

0.342 × X = 12

Divide both side by 0.342

X = 12 / 0.342

X = 35.09

Thus, the value of X is 35.09

After 8 weeks on a fitness program, mrs.Honaker can job 30 miles. Her average mileage gain has been 2 miles per week. Write an equation in slope intercept form to model this scenario.

Answers

Answer:

y = 2x + 14

Step-by-step explanation:

Equation in slope intercept form:

y = mx + c

From the scenario above ;

y = total miles = 30

Average mile gain per week = slope (m) = 2

Number of weeks (x) = 8

We can obtain intercept, c :

30 = 2(8) + c

30 = 16 + c

30 - 16 = c

14 = c

Hence,

Equation goes thus ;

y = 2x + 14

Line M is represented by the equation -2/3+8. Line W is perpendicular and passes through the point (4,3)

Answers

Answer:

y= -3/2x+9

Step-by-step explanation:

Well we have to know that to find a line perpendicular to a given line, you have to have opposite slopes. So that makes the equation begin as y=-3/2x because it's opposite of y=2/3x. Then we have to make sure it goes through the point (4,3). To do that, I tweaked the numbers in my graphing calculator and it worked with 9! So the equation is y= -3/2x+9

find the length of each bolded arc. Round to the nearest hundredth.

Answers

Answer:

Length of the bold arc = 72.63 ft

Step-by-step explanation:

Length of the arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]

Here, θ = angle subtended by the arc at the center

r = Radius of the circle

Since, angle subtended by the bold arc at the center = 360 - 73

                                                                                         = 287°

And radius of the circle 'r' = 14.5 ft

By substituting these values in the formula,

Length of the bold arc = [tex]\frac{287}{360}\times (2\pi)(14.5)[/tex]

                                     = 72.632

                                     ≈ 72.63 ft

Therefore, length of the bold arc = 72.63 ft

Step-by-step explanation:

Given:

Height of triangle joint = 4 m

Base = 12 m

Width = 8 m

Find:

Area of shape

Computation:

Area of shape = Area of triangle + Area of rectangle

Area of shape = (1/2)(Base x height) + [Base x Width]

Area of shape = (1/2)(12 x 4) + [12 x 8]

Area of shape = 24 + 96

Area of shape = 120 m²
