d. polynomial

Answer:

42 minutes.

Step-by-step explanation:

We know that:

y = 0.2*x

is the equation that that defines the distance, in miles, that the boat travels in x minutes.

We know that the dolphins are at 8.4 miles from the boat.

Then when we have y = 8.4, this will mean that the boat reached the dolphins.

Then we need to solve the equation:

y = 8.4 = 0.2*x

for x

To do that, we just need to isolate x in one side of the equation, so we can just divide both sides by 0.2 to get:

8.4/0.2 = (0.2*x)/0.2

42 = x

And x is time in minutes, thus, the boat needs to travel for 42 minutes to reach the dolphins.

Answer:

r·sin Ф = 5(r·cos Ф) - 2

Step-by-step explanation:

y = r·sin Ф and x = r·cos Ф, and so

y = 5x - 2 becomes

r·sin Ф = 5(r·cos Ф) - 2

Answer:

rsin(0) = 5rcos (0) - 2

Step-by-step explanation:

Convert y = 5x - 2 to polar coordinates.

To convert to polar apply: x = r · cos (0), y = r · sin (0)

The requreid if x = |9|, then x could only have one possible value, which is x = 9

The absolute value of a number is its distance from zero on the number line. When pointing to the absolute value of a positive number, the result is the same number.

The absolute value of 9 is 9 since 9 is already a positive number.

The absolute value of 9 is 9. Therefore, if x = |9|, then x could only have one possible value, which is x = 9

So the only possible value of x is 9.

Solution :

Let, slope of line is m.

We know, product of slope of in straight line is -1.

[tex]m \times \dfrac{-2}{3} = -1\\\\m = \dfrac{3}{2}[/tex]

We know, slope is given by :

Step-by-step explanation:

f(3) = 2(3)^2 - 3(3) + 5

f(3) = 2(9) - 9 + 5

f(3) = 18-9+5

f(3) = 14

f(-2) = 2(-2)^2 - 3(-2) + 5

f(-2) = 2(4) + 6 + 5

f(-2) = 8 + 6 + 5

f(-2) = 19

Answer:

6000 cm³

Step-by-step explanation:

Here, we have 2 cuboids. What we do is add the area of both together.

Area of a cuboid is l * b * h

Cuboid A, area = 20 * 15 * 10 = 3000

Cuboid B, area = 20 * 15 * 10 = 3000

3000 + 3000 = 6000

The Area of the lens is equal to 50.24 cm²

The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.

Given here: Elliana is using a magnifying glass and radius of the magnifying glass has radius of 4 cm.

The formula for the area of a circle is A = πr², where r is the radius of the circle. The unit of area is the square unit, for example, m², cm², in², etc.

Thus Area of the lens of the glass is equal to A=πr²

                                                                              =3.14×4²

                                                                              =50.24 cm²

Therefore the len's Area is 50.24 cm²

Hence, The Area of the lens is equal to 50.24 cm²

Answer:

∠CBA = 132

Step-by-step explanation:

Bisectors split up an angle into two identical angles

Thus, 7x - 11 = 2x + 44

This is the equation we will use to solve for x

7x - 11 = 2x + 44

step 1 add 44 to each side

44 + 11 = 55

-11 + 11 cancels out

we now have 7x = 2x + 55

step 2 subtract 2x from each side

7x - 2x = 5x

2x - 2x cancels out

we now have 5x = 55

step 3 divide each side by 5

5x / 5  = x

55 / 5 = 11

we're left with x = 11

The question is asking for the measure of ∠CBA

To find the measure of ∠CBA we plug in 11 for x in one of the given expressions and multiply that by 2 ( this is because the two angles are identical so there is no need to find the measures of both because ∠CBD≅∠ABD )

Step-by-step explanation:

Letters = (a, b, c)

Number of letters to be chosen = 2

If the order is relevant, then we use permutation :

nPr = n! ÷ (n-r)!

3P2 = 3! ÷ (3-2)!

3P2 = (3 * 2 * 1) ÷ 1

3P2 = 6

If the order is not relevant ; We use combination :

nCr = n! ÷ (n-r)!r!

3C2 = 3! ÷ (3-2)!2!

3C2 = 3! ÷ 1!2!

3C2 = (3 * 2!) ÷ 2! * 1

3C2 = 3

Explanation:

The smaller triangle on the left is a 45-45-90 triangle. In these triangles, the hypotenuse is sqrt(2) times that of the leg length.

The hypotenuse shown is 7*sqrt(2), so that must mean each leg is 7 units long. Therefore, a = c = 7.

The triangle on the right is a 30-60-90 triangle. The shorter leg (opposite the smallest angle of 30 degrees) doubles to get the hypotenuse. So we can say b = 2a = 2*7 = 14. The longer leg is exactly sqrt(3) times that of the shorter leg. The longer leg is d = a*sqrt(3) = 7*sqrt(3)
