Step-by-step explanation:

From the given expression in our example we have say

y = d-6d-3dd−6d−3d,

the equivalent expression would be  y = -14-3dd

We can see two different terms

the "d" terms and the "dd" terms

Let us collect like terms

we have

y= d-6d-6d-3d-3dd

y = d-12d-3d-3dd

y= d-15d-3dd

y = -14-3dd

Hence the equivalent expression is y = -14-3dd

Answer:

Step-by-step explanation:

To find the slope of the tangent at a point we will find the derivative of equation at that point.

a). y = x² - 10x

[tex]\frac{dy}{dx}=\frac{d}{dx}(x^{2} -10x)[/tex]

y' = 2x - 10

At (x = 2),

y' = 2(2) - 10

y' = 4 - 10

y' = -6

From the given equation,

y = 2² - 10

y = -6

Therefore, y-coordinate of the point is y = -6

Equation of the tangent at (2, -6) having slope = -6

y - 2 = -6(x - 2)  

y - 2 = -6x + 12

y = -6x + 14

b). y = [tex]x^{2}+\frac{2}{x}[/tex]

At x = [tex]\frac{1}{2}[/tex]

y = [tex](\frac{1}{2})^2+\frac{2}{\frac{1}{2}}[/tex]

y = [tex]\frac{1}{4}+4[/tex]

y = [tex]\frac{17}{4}[/tex]

Now we have to find the equation of a tangent at [tex](\frac{1}{2},\frac{17}{4})[/tex]

y' = 2x - [tex]\frac{2}{x^{2} }[/tex]

At x = [tex]\frac{1}{2}[/tex]

y' = [tex]2(\frac{1}{2})-\frac{2}{(\frac{1}{2})^2}[/tex]

y' = 1 - 8

y' = -7

Therefore, equation of the tangent at [tex](\frac{1}{2},\frac{17}{4})[/tex] will be,

[tex]y-\frac{17}{4}=-7(x-\frac{1}{2})[/tex]

y = -7x + [tex]\frac{7}{2}+\frac{17}{4}[/tex]

y = -7x + [tex]\frac{31}{4}[/tex]

Step-by-step explanation:

The sum of a triangle's angles is 180. So, 6x+2x+2x=180. And, 10x=180, and then x=18. Angle C is 2x. To find angle C multiple 18 by 2 to get 36.

Angle C =  45°

Step-by-step explanation:

Hello There!

If you didn't know opposite angles are congruent in parallelograms

So ∠A≅∠C and ∠B≅∠D

So if ∠A = 45° then ∠C also equals 45°

As it is a parallelogram

[tex]\\ \sf\longmapsto <A\cong <C[/tex]

Step-by-step explanation:

If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.

Answer: No 0.3 as a percentage is larger than 25%

Step-by-step explanation:

'percent' is 'over hundred'

if you convert 0.3 into a percentage it becomes 30 percent

Samuel says that 25% is greater than 0.3 is not correct statement.

A percentage is a number or ratio expressed as a fraction of 100.

The percentage is denoted by the symbol %.

The percentage is used or most important application is to compare any two quantities. We compare one quantity against another, with the second quantity rebased to 100 by using percentage.

Samuels  says that 25% is greater than 0.3 is a false.

25% when it is converted to decimals.

25 divided by 100

we will get 0.25

and if 0.3 is converted to percentage

0.3×100=30%

We know that 30% is greater than 25%.

hence Samuel says that 25% is greater than 0.3 is not correct.

a= - 1/4

Step-by-step explanation:

Answer:

- 1/4

Step-by-step explanation:

7a + 2 = 3a + 1

subtract the 1 from both sides

7a + 1 = 3a

subtract 7a from both sides

1 = - 4a

divide by - 4

A = - 1/4

Correct question is;

Consider these statements written in ordinary language:

A The speed of the car is proportional to the distance it has traveled.

B The car is speeding up.

C The car is slowing down.

D The car always travels the same distance in the same time interval.

E We are driving backwards.

F Our acceleration is decreasing. Denoting by s(t) the distance covered by the car at time t, and letting k denote a constant, match these statements with the following mathematical statements by entering the letters A through F on the appropriate boxes:

s′′<0.

s′ is constant

s′<0

s′′′<0

s′′>0

s′=ks

Answer:

Answers given below.

Step-by-step explanation:

F) acceleration is the second derivative of distance with respect to time.

Thus; s'' < 0

D) Car travels the same distance in the same time interval. This means the speed is constant. Speed is the first derivative of distance with time. Thus;

s' is constant

E) Driving backwards means that speed is; s' < 0

C) Car is slowing down means negative acceleration. Thus; s'' < 0

B) Car is speeding up means acceleration is greater than 0. Thus: s'' > 0

A) Car speed being proportional to the distance it has covered means that; s' ∝ s. Thus;

s' = ks

Scott filled (1/2 - 1/4) of the jar, or 1/4 of the jar this week.

Let me know if this helps!

Answer:

He filled his jar 1/4 more this week.

Step-by-step explanation:

The explanation is very simple, you know that he added 1/4 coins last week and this week he added more coins that filled the jar half way:

1/2 - 1/4 = 1/4

or you can also use:

1/4 + 1/4 = 1/2

Linear inequalities with two variables have infinitely many ordered pair solutions, which can be graphed by shading in the appropriate half of a rectangular coordinate plane. To graph the solution set of an inequality with two variables, first graph the boundary with a dashed or solid line depending on the inequality.

Answer:

The length of the ramp must be at least 14.71 feet

Step-by-step explanation:

Given

[tex]BC = 2.3ft[/tex]

[tex]\theta = 9^\circ[/tex]

See attachment for complete figure

Required

Length of the ramp (z)

To do this, we consider sin of angle A ([tex]\theta[/tex]).

So, we have:

[tex]sin\theta = \frac{Opposite}{Hypotenuse}[/tex]

This gives:

[tex]sin(9)= \frac{2.3}{z}[/tex]

Make z the subject

[tex]z= \frac{2.3}{sin(9)}[/tex]

[tex]z = \frac{2.3}{0.1564}[/tex]

[tex]z = 14.71 ft[/tex]

The length of the ramp must be at least 14.71 feet
