A rectangular field has an area of 162 m² the width of this field is 9m what is the perimeter of this field
Andru [333]

Answer:

54 m

Step-by-step explanation:

Alrighty, what have we here: an area of 162 m² and a width of 9m.

So: A=162m², W=9m, let's draw this: (see the screenshot attached)

Using the formula for area (Area = width x length) we see that:

162m^{2} =9m*L

Thus: (equating to L by dividing both sides by 9m)

⇒ \frac{162m^{2} }{9m}=18m=L

Now we have all of our dimensions, we can use the formula for the perimeter to calculate it:

perimeter=2W+2L=2*9m+2*18m=18m+36m=54m

And there we have our answer.

Find the range of the function F(x) = the integral from 0 to x of the square root of 4-t^2 dt
ioda

Note that √(4 - t²) is defined only as long as 4 - t² ≥ 0, or -2 ≤ t ≤ 2. Then the real integral exists only if -2 ≤ x ≤ 2. (Otherwise we deal with complex numbers.)

If x = 2, then the integral corresponds to the area of a quarter-circle with radius 2. This means that the integral has a maximum value of 1/4 • π • 2² = π.

On the opposite end, if x = -2, then the integral has the same value, but the integral from 0 to -2 is equal to the negative integral from -2 to 0. So the minimum value is -π.

For all x in between, we observe that the integrand is continuous over the rest of its domain, so F(x) is continuous.

Then the range of F(x) is the interval [-π, π].

gayaneshka [121]

Answer:

  • A. 3x° + (8x - 20)° = 90°

Step-by-step explanation:

The two given angles are complementary and sum to 90°

  • 3x° + (8x - 20)° = 90°

Therefore correct choice is A.

I need help with this I am giving 60 points
inna [77]

Answer:

<2 ≅<4 with reason of vertical angle theorem.

Step-by-step explanation:

The vertical angle theorem states that two opposite (non-adjacent) angles formed by 2 intersecting lines have equal measure. In this problem, we are given that the angles are vertical angles. So the statement is that <2 ≅<4 with reason of vertical angle theorem.
