What Is The Measure Of AX, In Degrees?N6670

Answers

Answer 1

Answer:

C

Step-by-step explanation:

Since XY = XZ = 6, then the triangle is isosceles.

The base angles are therefore congruent, that is

∠ Y = ∠ Z = 70°

The sum of the 3 angles in the triangle = 180°, thus

∠ X = 180° - (70 + 70)° = 180° - 140° = 40° → C

David kicks a ball off the ground. After t seconds, it’s height, h (in feet), is given by the formula h=-16t^2+80t. How many seconds does the ball reach its maximum height? What is the maximum height reached by the ball?

Answers

Answer:

The ball reaches its maximum height at 2.5 seconds

The maximum height is 100 feet

Step-by-step explanation:

Maximum Value of Functions

We use the derivative of a function to find its maximum or minimum value over a given interval.

Given a function y=f(x), the first derivative criterion establishes if x=a is such that:

f'(a)=0, and f''(a) < 0 then x=a is a maximum of f.

The height h in feet of a ball after t seconds is:

[tex]h(t)=-16t^2+80t[/tex]

Find the first derivative:

[tex]h'(t)=-32t+80[/tex]

Equate to 0:

[tex]-32t+80=0[/tex]

Subtract 80:

[tex]-32t=-80[/tex]

Divide by -32:

[tex]t = -80 / (-32) = 2.5[/tex]

t=2.5 seconds

Find the second derivative:

h''(t)=-32

Since h''(t) is always negative, then

The ball reaches its maximum height at 2.5 seconds

To find the value of the maximum height, substitute t=2.5 into the function:

[tex]h(2.5)=-16(2.5)^2+80*2.5=-100+200 = 100[/tex]

The maximum height is 100 feet

Malcolm and Theo's families are both traveling to the same vacation resort.
The equation d = 65t models the distance, d, that Malcolm's family travels after t hours.
The graph below shows the relationship between the distance and the amount of time that Theo's family traveled.

Answers

Answer:

Malcom's family travel 15 miles per hour faster than Theo's

Step-by-step explanation:

See attachment for complete question

Given

Malcom's Family:

[tex]d = 65t[/tex]

To determine the equation of Theo's family, we refer to the attached graph.

From the graph:

[tex]t = 1; d = 50[/tex]

[tex]t = 2; d = 100[/tex]

First, we determine the slope, m:

[tex]m = \frac{d_2 - d_1}{t_2 - t_1}[/tex]

[tex]m = \frac{100 - 50}{2- 1}[/tex]

[tex]m = \frac{50}{1}[/tex]

[tex]m = 50[/tex]

Next, we determine equation for Theo's family using:

[tex]d - d_1 = m(t - t_1)[/tex]

[tex]d - 50 =50(t - 1)[/tex]

[tex]d - 50 =50t - 50[/tex]

Add 50 to both sides

[tex]d - 50 +50=50t - 50 + 50[/tex]

[tex]d =50t[/tex]

So, we have the following:

[tex]d = 65t[/tex] --- For Malcom's family

This implies that Malcom's family travel at 65 miles per hour

[tex]d =50t[/tex] --- For Theo's family

This implies that Theo's family travel at 50 miles per hour

The difference between this rates is:

[tex]Rate = 65t - 50t[/tex]

[tex]Rate = 15t[/tex]

Which implies that Malcom's family travel 15 miles per hour faster than Theo's

Answer:

([tex]\frac{2}{3}[/tex], 2 )

Step-by-step explanation:

Given the 2 equations

3x + [tex]\frac{1}{2}[/tex] y = 3 → (1)

6x - y = 2 → (2)

Multiplying (1) by - 2 and adding to (2) eliminates the term in x, that is

- 6x - y = - 6 → (2)

Add (2) and (3) term by term to eliminate x

- 2y = - 4 ( divide both sides by - 2 )

y = 2

Substitute y = 2 into either of the 2 equations and solve for x

Substituting into (2)

6x - 2 = 2 ( add 2 to both sides )

6x = 4 ( divide both sides by 6 )

x = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]

Solution is ( [tex]\frac{2}{3}[/tex], 2 )

Pls help

Answers

Answer:   37.2 pounds per liter

Step-by-step explanation:

The density of the material of 4 kg/cup on converting it into pounds per litre will be 37.2 lbs/lt.

Given that, the density of a certain material is such that it weighs 4 kilograms per cup of volume.

What are derived units?

Defining a derived unit is the process of deriving a measurement unit from one or more of the seven base units of the international system of units (SI). There are two types of derived units: dimensionless and the product of base units.

Here it is given that, the density d of a certain material is 4 kilograms per cup of volume and it is finding the density of material in pounds per litre.

Now it is known that,

1 kg equals 2.2 pounds

Now, 1 cup of volume equals 0.237 lt.

Converting the density d of material in pounds per litre and rounding it to the nearest tenth:

d=4 kg/cup

=4×2.2/0.237

=37.13≈37.1 pounds/lt

Therefore, the density of the material of 4 kg/cup on converting it into pounds per litre will be 37.2 lbs/lt.
