Answer:

Step-by-step explanation:

A third degree polynomial has a total of three roots, real and imaginary combined.

If it already has 2 real roots, -4 and +4, then it has to have three real roots because imaginary roots come in conjugate pairs, i.e. they come in even numbers.

Answer:

Three real roots

34.6 m is the correct answer.

The scale used by Johnny for the drawing is 1/10. This means that every 1 millimeter on the drawing represents 10 meters in reality.

To determine the scale used by Johnny for the drawing, we need to compare the measurements in the drawing to the actual measurements of the soccer field. We can set up a proportion to find the scale.

Let's denote the scale as x (the ratio of the drawing measurements to the actual measurements). According to the information provided, the width of the soccer field in the drawing is 6 millimeters, while the actual width is 60 meters.

We can put up the following proportion using the scale:

6 millimeters / x = 60 meters / 1

We can solve for x by cross-multiplying and then dividing:

6 millimeters * 1 = 60 meters * x

6 = 60x

Dividing both sides by 60:

6 / 60 = x

1 / 10 = x

Therefore, the scale used by Johnny for the drawing is 1/10. This means that every 1 millimeter on the drawing represents 10 meters in reality.

Answer:

x ≈ 24.7

Step-by-step explanation:

Using the Sine rule in the triangle , that is

[tex]\frac{x}{sin71}[/tex] = [tex]\frac{15}{sin35}[/tex] ( cross- multiply )

x × sin35° = 15 × sin71° ( divide both sides by sin35° )

x = [tex]\frac{15sin71}{sin35}[/tex] ≈ 24.7 ( to the nearest tenth )

Answer:

  ∠GDH = ∠GHD = 50°

Step-by-step explanation:

Angles FGD and EDG are alternate interior angles, so are congruent. That means angle EDG is 100°. The angle sum theorem tells us ...

  ∠EDG = ∠EDH +∠HDG

  100° = 50° +∠HDG

  50° = ∠HDG

You can find the measure of ∠DHG a couple of different ways. It is an alternate interior angle congruent to ∠EDH, so is 50°. It is one of two remote interior angles that have  a sum equal to the exterior angle FGD, so is ...

  ∠DHG = ∠FGD -∠HDG = 100° -50° = 50°

So, angles DHG and HGD both have measures of 50°. When a triangle has two angles with the same measure, it is an isosceles triangle.

Answer:

The volume of the triangular prism is 5676.16 cm³

Step-by-step explanation:

The area of the triangular base A = bh/2 where b = base = 28 cm and h = height = 22.4 cm.

Now, the volume of the triangular prism, V = area of triangular base, A × height of prism, h'

V = Ah' where h = height of prism = 18.1 cm

So, V = bhh'/2

Substituting the values of the variables into the equation for V, we have

V = bhh'/2

V = 28 cm × 22.4 cm × 18.1 cm/2

V = 14 cm × 22.4 cm × 18.1 cm

V = 5676.16 cm³

So, the volume of the triangular prism is 5676.16 cm³

Answer:

V = (8 in)(5 in)(3 in) = 120 in^3

Step-by-step explanation:

The likeliest name for this shape is "rectangular prism."  Let's assume that the length, L, is 8 in; the width, W, is 5 in; and the height, H, is 3 in.

Then the volume of this rectangular prism is V = L * W * H, or

V = (8 in)(5 in)(3 in) = 120 in^3

Answer:

4 batches

Step-by-step explanation:

To obtain the number of batches of the recipe that can be made ;

We take the divison of the total amount of strawberry by the amount of strawberry required per batch :

Pounds of strawberry per recipe = 0.75 pound

Total pounds of strawberry = 3.15 pound

= 3.15 / 0.75

= 4.2

We round down :

4.2 batches = 4 batches of the recipe can be made
