Answer:

I believe it is C. I am not 100% sure but I do believe I am right

Answer:

D

Step-by-step explanation:

These two triangles are similar triangles. The two angles marked are the same and the two angles at the intersection where you see the square are also the same, making it clear that the last angle must be the same as well.

Therefore,

length 8 from the top triangle is similar to length 6 on the bottom triangle,

length 10 from the top is similar to b on the bottom triangle,

length 6 from the top is similar to a on the bottom.

To find the ratio of similarity, you would compare the length 8 to length 6, and divide them. 8/6 = 1.33333

Now that you've found the proportionality constant, you divide the other two lengths on the top triangle with the constant to get b and a.

b = 10/1.3333 = 7.5

a = 6/1.3333 = 4.5

Therefore, the answer is D: a = 9/2, b = 15/2.

Answer: 11/3, or 3.66 (repeating)

Step-by-step explanation: 3x + 11, divide 11 by 3, getting a repeating decimal, or a fraction that cannot be simplified

The discriminant is greater than zero, the equation has 2 solutions

Given the quadratic expression as shown:

-x^4 + 4x + 1 + 3 = 0

x^4 - 4x - 4 = 0

The discriminant is given as b^2 - 4ac

where;

a = 1

b = -4

c = -4

Substitute

D =(-4)^2 - 4(1)(-4)

D = 16 + 16
D = 32

Since the discriminant is greater than zero, the equation has 2 solutions

The measure of base angle of the isosceles right angle triangle is 45°.

A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any angle is a right angle.

Given that,

Triangle ABC is an isosceles right angle triangle.

In an isosceles triangle, two sides are equal and corresponding angles are equal.

Let the corresponding angles are α and α.

Since, one angle of right angle isosceles triangle is 90°.

Also, the sum of angles of triangle is 180°

Implies that,

α  + α  + 90 = 180

2α  = 180 - 90

2α  = 90

α  = 45

The required value of angle α  is 45°

Answer:

Step-by-step explanation:

a) Friction opposes motion, so is in the opposite direction of the net force on the sled. Taking "left" to be "positive", the two animals are applying a net force of +42 N -15 N = 27 N. That is to the left, so the friction force is to the right.

__

b) The total of forces applied by the animals and friction is ...

  27 N -5 N = 22 N . . . to the left

__

c) Acceleration can be found from the relation ...

  a = F/m . . . . 'm' is mass

  a = (22 N)/(15 kg) = 22/15 m/s² . . . . 'm' is meters

__

d) The coefficient of friction is the ratio of friction force to the normal force on the surface producing the friction. Here, that normal force is the force due to gravity acting on the 15 kg mass of the sled.

 coefficient of friction = (5 N)/(9.8 m/s²·15 kg) = 5/147

 coefficient of friction ≈ 0.034

Answer:

1. to the right

2. 22 N

Step-by-step explanation:

This equation is in y=mx+b form, so to graph this equation, take the y-intercept which would be 12. Go on your graph and make twelve on the y-axis (you can go by two's or even six's). Then take your slope which would be -6 and use rise of run which would be down 6, since it's negative, and to the right one. Keep repeating this process until you ran out of space. Draw a line between the points and you have graphed a line.

Answer:

The answer is: y = 9.25x

Step-by-step explanation:

Let the equation for the proportionality relation is y = mx .......... (1), where y represents the money that Craig earns for a duty of x hours.

Here, m is the constant of proportionality and we have to find its value.

Given that Craig earns $37 for 4 hours duty.

So, from equation (1), we have 37 = 4m, ⇒ m = 9.25

Therefore, the equation becomes y = 9.25x. (Answer)
