Answer:

Circumference of the ractangular = 12 + 12 + 5 + 5 = 34 m

Diagonal =  sqrt{12^{2} + 5^{2}}  = 13 m

Total length in meters = 34 + 13 = 47 m

Total weight in Kg = (47)(1.5) = 70.5 Kg

How do you know how many places are in fifty million without writing the number in standard form
wolverine [178]
We know that 1 million has 6 zeros. This means 1 million has 7 place values: one for the 1 and 6 for the zeros.

50 has 1 more place value than one, so 50 million has 1 more place value than 1 million.

So, 50 million has 8 place values.

An acrobat is on a platform that is 25 feet in the air. She jumps down in the initial velocity of 4 feet/seconds . Write the qua
Alenkasestr [34]

Answer:

a) h(t) = -16t²+ 4t + 25

b) Therefore it would take her 1.25 seconds to land safely in the net.

Step-by-step explanation:

The equation to be used is given as

h(t) = –gt²+ vt + S(t)

where g = force of gravity and because our question is in feet's = 16

V= Initial velocity

h = height

S = distance

a) The quadratic function for the above question

Using the formula

v = Initial velocity in the question = 4ft/s

S(t) = 25ft in the air

Hence the Quadratic function is

h(t) = –gt²+ vt + S(t)

h(t) = -16t²+ 4t + 25

b) If the safety net is placed 5 feet above the ground, how long will it take her to land safely in the net?

We are to find the time(t)

We can calculate this by using the quadratic function we derived in question (a)

The quadratic function is

h(t) = -16t²+ 4t + 25

Where, the height (h) = 5 feet above the ground

5= -16t² + 4t + 25

-16t² + 4t + 25 -5 = 0

-16t² + 4t + 20 = 0

Using the quadratic equation formula of

x = -b ± √b² -4ac /2a

where the quadratic equation =

ax² + bx + c = 0

a = -16 , b = 4 , c = 20

x = -16 ± √4² - 4×-16×20 / 2×-16

x = -1 or ,1.25

Therefore it would take her 1.25 seconds to land safely in the net

VARVARA [1.3K]

Answer:

64 ft²

Step-by-step explanation:

10 ft · 10 ft

100 ft²

A=\frac{bh}{2}

6 · 6 = 36

36 ÷ 2 = 18

18 ft² + 18 ft² = 36 ft²

100 ft² - 36 ft²

64 ft²

Based only on the information given in the diagram, which congruence
professor190 [17]

The congruence theorems or postulates that could be given as reasons why ACDE=AOPQ are:

  • AAS
  • HA
  • ASA

<h3>What is this  congruence theorems about?</h3>

Note that in the diagram, there has been given one side that is congruent to its other corresponding side and as such, it has remove the option or postulates that needs the HL and SAS sides.

Conclusively, when all three angles are said to be congruent and when they have one side (known as the hypotenuse), one can use the congruence theorems or postulates of  AAS, HA and ASA.
