Answer:

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

Answer: Militarism could have cause the war due to the naval and arms race. The main event of Militarism causing World War one was the naval rivalry which was made after 1900. Britain had the most powerful navy in the world. The new Keiser Wilhelm announced his intention to build a bigger German navy than Britain. Britain felt very threatened by this. Germany’s navy was much smaller than Britain’s navy but the British army was put all over its colonies so they can be protected. Germany didn’t have a big Empire like Britain but most people agreed, at the time, they were the best trained and the most powerful. The Kaiser felt he needed a bigger navy than Britain to protect its country.

Answer:

No.

Step-by-step explanation:

Triangle DFE justifies itself with the SAS (side-angle-side) postulate, while Triangle ABC simply shows that ∡B & A are similar. They are not justified by the same standard, and so there is no way to tell if these triangles are similar.

Answer:

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 <B\cong <D[/tex]

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

[tex]\\ \sf\longmapsto <C=<A=45°[/tex]

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: A - 33/100

Step-by-step explanation:

You have to multiply the first fraction by 10 to make 100 the least common denominator - 3/10(10) = 30/100

Add 30/100+3/100 = 33/100

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]

Answer:

  A: a unique triangle

  B: no triangle

  C: more than one triangle

Step-by-step explanation:

A: Two sides and the included angle are sufficient to completely specify one triangle. (See the first attachment.)

__

B: The given side lengths do not satisfy the triangle inequality. No triangle can be formed. (See the second attachment.)

__

C: The angles total 180°, so a triangle can be formed with those angles. However, the side lengths are not specified, so any number of triangles can be made with those angles.

Answer:

A. a unique triangle

B. no triangle

C. more than one triangle

Answer:

Este acontecimento se repetirá 300 dias depois.

Step-by-step explanation:

Quando os eventos se repetirão no mesmo dia?

Cada evento tem uma frequência.

Eles ocorrem simultaneamente a cada x dias, e x é dado pelo MMC(Mínimo Múltiplico Comum) entre as frequência.

Neste problema:

A cada 15 dias o avô visita.

A cada 100 dias o tio visita.

A cada 12 dias vai à praia.

Quantos dias depois este acontecimento se repetirá?​

Os três no mesmo dia vão se repetir após x dias, em que x é dado pelo MMC de 15, 100 e 12

MMC de 15, 100 e 12

Fatorando simultâneamente estes valores:

15 - 100 - 12|2

15 - 50 - 6|2

15 - 25 - 3|3

5 - 25 - 1|5

1 - 5 - 1|5

1 - 1 - 1

Então:

mmc(15,100,12) = 2*2*3*5*5 = 300

Este acontecimento se repetirá 300 dias depois.

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:

36º

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.

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
