Is D correct? if not what is? and how many months with the population of the towns be equal​

Answer:

[tex]\displaystyle 10 + 12\sqrt{3}[/tex] metres

Step-by-step explanation:

You are finding the height of the building with an angle of elevation, therefore we need to solve for EC to add it to BA [10 metres] and use TRIGONOMETRIC RATIOS to arrive at our conclusion. Just in case you have forgotten what they were, here they are:

[tex]\displaystyle \frac{OPPOSITE}{HYPOTENUSE} = sin\:θ \\ \frac{ADJACENT}{HYPOTENUSE} = cos\:θ \\ \frac{OPPOSITE}{ADJACENT} = tan\:θ \\ \frac{HYPOTENUSE}{ADJACENT} = sec\:θ \\ \frac{HYPOTENUSE}{OPPOSITE} = csc\:θ \\ \frac{ADJACENT}{OPPOSITE} = cot\:θ[/tex]

We can now solve for EC:

[tex]\displaystyle cot\:60 = \frac{12}{EC} → ECcot\:60 = 12 \\ \\ \frac{ECcot\:60}{cot\:60} = \frac{12}{cot\:60} → 12\sqrt{3} = EC[/tex]

OR

[tex]\displaystyle tan\:60 = \frac{EC}{12} → 12tan\:60 = EC → 12\sqrt{3} = EC[/tex]

Now that you have solved for EC, you can now add it to your original 10 metres to get [tex]\displaystyle 10 + 12\sqrt{3}[/tex] metres. As a decimal, you would get [tex]\displaystyle 30,78460969...[/tex] metres. You can go ahead and round this off if necessary.

** The reason why the cotangent [or tangent] ratio was used was because EA is equivalent to DB by the definition of a rectangle. It has two pairs of parallel and congruent sides with four right angles. Plus, that is the adjacent side of the triangle, while EC is the opposite side of the triangle, so we knew our ratios were correct.

Answer:

[tex]x^2 + y^2 + z^2 \le 25[/tex] for [tex]z \ge 0[/tex]

Step-by-step explanation:

Given

[tex]r = 5[/tex] --- radius

Required

Determine the inequality of the region

The inequality of a region of a sphere is determined using:

[tex]x^2 + y^2 + z^2 \le r^2[/tex]

Substitute 5 for r

[tex]x^2 + y^2 + z^2 \le 5^2[/tex]

[tex]x^2 + y^2 + z^2 \le 25[/tex]

Solving further: The question says only the upper hemisphere is considered.

This implies that:

[tex]z \ge 0[/tex]

So, the equation is:

[tex]x^2 + y^2 + z^2 \le 25[/tex]

[tex]z \ge 0[/tex]

Answer:

The y-intercept is y = 80feet. The initial height of the balloon is 80feet.

Step-by-step explanation:

[tex]h(x)=-16x^2+64x+80[/tex]

The y-intercept of the function happens when the x-value = 0. So let's plugin x=0 into the function:

[tex]h(x)=-16x^2+64x+80\\h(x)=-16(0)^2+64(0)+80\\h(x)=80[/tex]

The y-intercept is y = 80feet

x represents the number of hours after starting its ascent from the hill, so x = 0hr means when the balloon is just starting to ascent. At the start of the ascent, the balloon has an altitude of 80feet. The initial height of the balloon is 80feet.

The y-intercept is y = 80feet.

The initial height of the balloon is 80feet.

Since the equation is [tex]h(x)=-16x^2+64x+80[/tex]

So here x = 0

So

[tex]h(x)=-16(0)^2+64(0)+80[/tex]

= 80

Here, The y-intercept is y = 80feet

Also,

x means the number of hours after starting its ascent from the hill

The area of the circle is 530.66 square inches.

The circumference, which is the distance around the object, the diameter, which is the length of a circle measured from one end to the other and passing through its center, and the radius, which is equal to half of the diameter, are the three key characteristics.

Given, A circular "No Parking" road sign has a diameter of 26 inches.

From the general formula of the area of the circle:

Area = π r²

Where r = radius

in our case,

r = diameter/2

r = 26/2

r = 13 inches

Thus,

the area of the circle = pi * 13 * 13

the area of the circle = 530.93 inches²

Therefore, The area of the circle is 530.66 square inches.

11. ........

Answer: 11

Step-by-step explanation:

We need to start by evaluating the problem, we can simplify this equation so its easier to solve.

So the new equation will be [tex]56-17-43+15[/tex].

56 - 17 = 39

39 - 43 = -4

-4 + 15 = 11.

So [tex]56-17-43+15 = 11[/tex].

Answer:

She is not breaking even. The discounted price is .84t, which is less than t.

Step-by-step explanation:

Retail price= 1.4

1.4×.4= .56

40% of 1.4 is .56

Subtract 40% of 1.4 from the retail price because she is marking down.

(1.4)-(.56)=.84

So the discounted price is .84t

This problem is difficult because we don't know if she sold any tea by the retail price and if she did how much did she sell.
