if a peregrine falcon dove at its maximum speed for half a mile to catch prey, how many seconds would the dive take? (round your answer to the nearest second.)
The time taken by peregrine falcon dove at its maximum speed to cover half a mile is 9 sec.
Who is peregrine falcon dove?It can be found with in Arctic tundra of North America and Greenland, and it migrates to Central and South American countries as during winter.The peregrine falcon is the world's swiftest bird, diving to acquire its prey at speeds of over 321 kph (200 mph). They are also among the most tolerant species and can flourish in populated places.For the given question;
The maximum speed of peregrine falcon dove is 200 mph.
Time of travel = 0.5 miles.
The relation of distance and speed is;
speed = distance/time
200 mph = 0.5 miles / time
Time = 0.5 miles / 200 mph
Time = 0.5 × 60 × 60 miles / 200 m/ sec
Time = 9 sec
Thus, time taken by peregrine falcon dove at its maximum speed to cover half a mile is 9 sec.

if
x/y=y/z=z/x
show that x=y=z
Step-by-step explanation:
x/y = y/z = z/x
x = y²/z = zy/x and y = z²/x
x = y²/z
putting this into the 3rd part of the original equation :
z/x = z/ y²/z = z²/y²
now using the y identity of the second part there :
y = z²/x
z²/y² = z² / z⁴/x² = x²/z² (= z/x per previous equation)
so,
x²/z² = z/x
x³/z³ = 1
x/z = 1
x = z
then
y/z = y/x = z/x (= 1)
and therefore,
y/x = z/x meaning
y = z (and therefore = x)
so,
x = y = z

find the equation of the line in slope-intercept form. e through (−5, 6) with slope = 2
Answer:
Step-by-step explanation:
Slope-intercept form is y=mx+b where m is your slope and b is your y-intercept.
To find your equation with what you are given, you have to plug in your values.
(-5, 6) = (x, y) so plug -5 in where there is x and 6 in where there is y
then your slope, m, is 2 so plug 2 in where there is m.
so it should look like
6=2(-5)+b, now you are solving for b.
6 = -10+b
+10 +10
___________
16 = b Then take the values and plug back into the slope intercept formula, y=mx+b.
Plug 16 in for b and 2 in for m (m represents slope and they told us the slope =2)
*you no longer need the y and x values because you only use those to solve for m or b, in this case b, so leave y and x in your equations*

the initial number of views for a reader board was 25. the number of views is growing exponentially at a rate of 18% per week. what is the number of views expected to be four weeks from now? round to the nearest whole number.
The number of views in the four weeks round to the whole number is 48.
Here it is given that the initial number of views for a reader board was 25 and it gets increased at the rate of 18% per week.
We have to find the number of views in the fourth week.
On the first week the increase = 25 + 25× 18%
= 25 + 25 × 18/100
= 25 + 4.5
= 29.5
The second week increase = 29.5 + 29.5 × 18%
= 29.5 + 5.31
= 34.81
The third week increase = 34.81 + 34.81 × 18%
= 34.81 + 6.2658
= 41.0758
The fourth week increase = 41.0758 + 41.0758 × 18%
= 41.0758 + 7.393644
= 48.469444
Therefore the number of views in the four weeks is 48.

Find DE, please help me
Step-by-step explanation:
ABC and CDE are similar triangles.
similar shapes means that both shapes have the same angles. and : that there is one scaling factor for all lines of one of the shapes to calculate the lengths of the lines of the other shape.
we see that all the other sides of ABC are scaled 2:1 to the corresponding sides of CDE. that means the sides of ABC are twice a long as the sides of CDE.
the same scaling factor has to apply to AB vs. DE.
therefore,
11x - 25 = 2(4x + 1) = 8x + 2
3x = 27
x = 9
DE = 4x + 1 = 4×9 + 1 = 36 + 1 = 37
A bowling ball is pushed with a force of 22. 0 N and accelerates at 5. 5 m/s2. What is the mass of the bowling ball?
When a bowling ball is propelled with a force of 22. 0 N and accelerates at a rate of 5. 5 [tex]ms^{-2}[/tex], its mass is 4. 0 kg.
Newton's Second Law of Motion states that force is the result of mass times acceleration.
[tex]F=m*a[/tex]
[tex]m = F / a[/tex]
A force of 22.0 Newtons ( [tex]kgms^{-2}[/tex] ) and an acceleration of 5.5 meters per second squared were used to drive the bowling ball.
F = 22.0 [tex]kgms^{-2}[/tex] and
a = 5.5 [tex]ms^{-2}[/tex]
Put the values in the formula as replacements.
M = 22 [tex]kgms^{-2}[/tex]/ 5.5 [tex]ms^{-2}[/tex]
Meters per second squared (m/s2) units cancel each other out.
M = 22 kg / 5.5

The community hall needs re-decorating
with new paint for the walls and ceiling,
and new tiles on the floor.
A 10 litre tin of paint covers 25 m² and costs £10.
Work out the total cost of paint needed
to re-decorate the community hall.
The total cost of painting is $564.
What is surface area of cuboid ?
A cuboid is a three-dimensional figure enclosed by six rectangular planes, each of which has a different size in terms of length, breadth, and height. Anything in the shape of a rectangle, such as a box, brick, or other object, may be a cuboid if you look about. When viewed from any of the ends, a cuboid (3-dimensional) can be seen to be made up of different-sized rectangles (2-dimensional). A cuboid's area is its surface because it is a solid with three dimensions. Since a cuboid's faces are rectangular, its area may be determined using the formula for the area of a rectangle.
Total Surface Area of a Cuboid (TSA) = 2 (lw + wh + lh) square units
We have been given that a community hall is in the shape of a cuboid. The hall is 40m long 15m high and 3m wide.
The paint will be required for 4 walls and ceiling.
Let us find area of walls and ceiling.
Area of walls and ceiling = 2( 40*15) + 2(3*15) + (40*3)
=> Area of walls and ceiling = 2(600)+2(45)+120
=> Area of walls and ceiling = 1200+90+120
=> Area of walls and ceiling = 1410 [tex]m^2[/tex]
Therefore, the area of walls and ceiling is 1410 square meters.
Here Cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter.
Then total cost of paint = 10*[tex]\frac{1410}{25}[/tex] = 10*56.4 = $564.

it takes a hose 3 minutes to fill a rectangular aquarium 8 inches long, 11 inches wide, and 13 inches tall. how long will it take the same hose to fill an aquarium measuring 26 inches by 33 inches by 35 inches?
It takes almost 5.7 hours the same hose to fill an aquarium measuring 26 inches by 33 inches by 35 inches.
First, we must determine how quickly the hose operates.
By dividing the volume of the first aquarium by the length of time it took to fill it, we may determine that.
The following formula can be used to determine the volume of the first aquarium: V =L*B*H
where the aquarium's length is L and its width is B
Its height is H.
Thus, the first aquarium's volume is:
V =L*B*H = 3*8*11 = 264 inches^3
We have the filling rate as:
264/3 inches ^3 per minute,
Let's now determine the second aquarium's volume.
The first formula is what we employ.
The volume is as follows:
V =L*B*H = 26*33*35 = 30030 inches ^3
Now, we divide the capacity of the second aquarium by the pace of the first aquarium to obtain the amount of time.
According to mathematics, that is:

Answer:
Im gonna assume its counter clockwise (excuse the bad drawing)
Step-by-step explanation:
The vertices of triangle F'G'H' after a rotation of 180° about (-3, -6) are F'(0, 10), G'(5, 6) and H'(2, 4).
What is rotation?Rotations are transformations that turn a shape around a fixed point. To rotate a shape we need: a centre of rotation. an angle of rotation (given in degrees) a direction of rotation – either clockwise or anti-clockwise.
Given that, triangle FGH has vertices F(-3, 4), G(2, 0), and H(-1, -2).
180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y).
So, (x, y) → (x+3, y+6)
F(-3, 4) → (-3+3, 4+6) → F'(0, 10)
G(2, 0) → (2+3, 0+6) → G'(5, 6)
H(-1, -2) → (-1+3, -2+6) → H'(2, 4)
Therefore, the vertices of triangle F'G'H' after a rotation of 180° about (-3, -6) are F'(0, 10), G'(5, 6) and H'(2, 4).
