Rewrite the equation so that it does not have fractions, without using decimals (please answer quickly)

Answer:

m∠T = 60°

m∠U = 60°

TS = 13 cm

SU = 13 cm

Step-by-step explanation:

The diagram shows that 2 sides, UT and TS, are equal, so it is an isosceles triangle. Since it is an isosceles triangle, the two angles opposite the equal sides are also congruent to each other, so m∠S = m∠U = 60°.

Now we know the measure of 2 angles, we can find the measure of the third angle, by subtracting the 2 known angles from 180°.

m∠T = 180° - m∠S - m∠U

m∠T = 180° - 60° - 60°

m∠T = 60°

Since all 3 angles are congruent, it is an equilateral triangle, therefore all the sides must be congruent too. So UT = TS = SU = 13 cm.

Answer:

Step-by-step explanation:

Slope of a straight line is the gradient of that line.

Formula for gradient is rise over run. Meaning: m = (y2 - y1) / (x2 - x1)

To use this formula, you need 2 points of the straight line. They have already given you one: (8, -3). For the second one, we consider the equation of the line. The y-intercept is given too: -4.

Now, keep in mind, the y intercept is the point of the line that passes from x = 0. Meaning, the point where the line touches the y axis, and at y axis, x = 0. So our second point is (0, -4).

Now as we have 2 points, (8, -3) and (0, -4), we put the values in the formula: m = (y2 - y1) / (x2 - x1) = (-4 - (-3)) / (0 - 8) = -1 / -8 = 1 / 8

Answer:

[tex]\sf y =\dfrac{-1}{5}x-\dfrac{1}{4}[/tex]

Step-by-step explanation:

Here, m is the slope and b is the y-intercept.

Substitute the values of m and b in the above equation.

  [tex]\sf m = \dfrac{-1}{5} \\\\b = \dfrac{-1}{4}[/tex]

       Slope y-intercept form:

              [tex]\sf \boxed{y=\dfrac{-1}{5}x - \dfrac{1}{4}}[/tex]

The reason that proves the above conditions is option A. Definition of supplementary angles And Substitution property.

The pair of angles that gives 180° on adding is known as Supplementary angles. In other words, the sum of two supplementary angles is 180°. Two pairs of Supplementary angles will always form a linear pair.

Here we have

∠1,  ∠2,  ∠3, and ∠4 are formed by 2 intersecting lines

As we know      

∠1,  ∠2 is a linear pair and form supplementary angles

=> Sum of the ∠1,  ∠2 will equal 180°  

∠2,  ∠3 is a linear pair and form supplementary angles

=> Sum of the ∠2,  ∠3 will equal 180°  

Therefore,

By the Definition of supplementary angles ∠1+∠2= 180° and ∠2+∠3= 180°

From the above observations,

=> ∠1+∠2= 180° and ∠2+∠3= 180°

=> ∠1 + ∠2 = ∠2 + ∠3  

Therefore,

By the Substitution property ∠1 + ∠2 = ∠2 + ∠3  

Hence,

The reason that proves the above conditions is option A. Definition of supplementary angles And Substitution property

As per the angle sum property of quadrilateral, then values of x is 245 and the value of y is 341

Angle sum property of quadrilateral:

The angle sum property states that the sum of all the angles of the quadrilateral is 360 degree.

Given,

The angles of the quadrilateral are 5x degrees, (4y minus 2 )degrees, (13x plus 10 )degrees, and 10y degrees.

Now we have to write and solve a system of linear equations to find the values of x and y.

While we looking into the given angles, then we get the values

=> 5x°

=> (4y - 2)°

=> (13x + 10)°

=> 10y°

We know that, the sum of all the angles of the quadrilateral is 360°.

So, it ca be written as,

=> 5x° + (4y - 2)° + (13x+ 10)° + 10y° = 360°

=> 18x° + 14y° - 8° = 360°

=> 18x° + 14y° = 354°

When we divide all of them by 2, then we get the equation as,

=> 9x° + 7y° = 177°

Now we have to rewrite the given equation as,

=> 9x° = 177° - 7y°

=> x° = (177° - 7y°)/9

Apply these value on the angles, then we get,

=> 13(177 - 7y)/9 = -10

=> 13(177 - 7y) = 90

=> -7y = -90 - 2301

=> 7y = 2391

=> 341

Then the value of x is

=> 245

A z-test with a z observed of 2.56 (two-tailed) would have a p-value of 0.010467 , which would lead a research to reject the null hypothesis if alpha is .05.

Given:

z - score = 2.56

p value at z = 2.56 is:

p = 0.010467

The result is statistically significant: you can reject the null hypothesis and accept the alternative.

This decision is made at significance level α = 0.05.

Answer:

y = 1/2x + 3

Step-by-step explanation:

first we change the first equation to slope-intercept form to find the reciprocal slope

2y - 4x = -10

add 4x to both sides

2y = 4x - 10

divide both sides by 2

y = 2x - 5

since perpendicular lines have reciprocal slopes the slope of our new line is 1/2

y = 1/2x + b

to find b we plug in the point

1 = 1/2(-4) + b

1 = -2 + b

add 2 to both sides

3 = b

our new line is

Step-by-step explanation: how i figured this out is by guessing so i can get more points sorry guys.

12 is the marginal cost at the production level of 1000 units.

A differential equation is an equation that contains one or more functions with its derivatives.

The marginal cost represents the additional cost if 1 more unit is produced. So, we can find the marginal cost by computing C(1,001) and subtracting (1,000)

First, let's evaluate the cost at both x= 1,001 and x=1,000

C(1000)=0.002(1000)^2+8(1000)+6000

=0.002(1000000)+8000+6000

=2000+8000+6000

=16000

C(1001)=0.002(1001)^2+8(1001)+6000

=2004.002+8008+6000

=16012

The difference between these costs is $12.002. Rounding to the nearest cent, we find a marginal cost of $12 per unit. Let's see if we get a similar result from the derivative.

Hence 12 is the marginal cost at the production level of 1000 units.
