Considerando que a lei de formação permanecerá a mesma, a figura que ocupará a posição 53a na sequência dada, será:
Answers
Answer:
C) Equal to the figure in position 3.
Step-by-step explanation:
Assume the sequence of figures is like the one below.
The pentagons differ in the number of stars in the sequence:
1, 2, 3, 4, 5, 1, 2, 3, 4, 5…
The sequence repeats after the fifth term.
To find the 53rd term, find the remainder for 53 ÷ 5.
53 ÷ 5 = 10, with a remainder of 3.
This tells you there are ten complete sequences (50 numbers), and three more numbers.
The 53rd term is 3, so
The figure that will occupy position 53 in the sequence is equal to the figure in position 3.
your garden has a perimeter of 36 feet. what is the length of missing side.
Answers
Answer:
I think the answer is 3 for 1 length side. And in you need 12 for both length sides. So the total is 36 and one side is 12. Since it's a rectangle,you now know two side lengths since they are the same,just opposite from each other. So 12 + 12 = 24. You do 36 – 24 because you need to get the total number for length which is 12. 12 divided by 2 is 6 which is one length side. You can check by doing 6 + 6 + 12 + 12 and you get 36.

Answer:
p = ± q / 5r + 8; Option D
Step-by-step explanation:
We are given the following equation; q^2 / p^2 - 16p + 64 = 25r^2;
q^2 / p^2 - 16p + 64 = 25r^2 ⇒ Let us factor p^2 - 16p + 64, as such,
p^2 - 16p + 64,
( p )^2 - 2 * ( p ) * ( 8 ) + ( 8 )^2,
( p - 8 )^2 ⇒ Now let us substitute this into the equation q^2 / p^2 - 16p + 64 = 25r^2 in replacement of p^2 - 16p + 64,
q^2 / ( p - 8 )^2 = 25r^2 ⇒ multiply either side by ( p - 8 )^2,
q^2 = 25r^2 * ( ( p - 8 )^2 ) ⇒ divide either side by 25r^2,
q^2 / 25r^2 = ( p - 8 )^2 ⇒ Now apply square root on either side,
| p - 8 | = √( q^2 / 25r^2 ) ⇒ Simplify,
| p - 8 | = q / 5r,
| p | = q / 5r + 8,
Answer; p = ± q / 5r + 8; Option D

A square pyramid has a base of total area of 144 m square root 2 and a volume of 384m cubic what is the slant height of the pyramid?
Answers
Answer:
Slant height of the pyramid = 11.66 m
Step-by-step explanation:
A squad pyramid has a volume of
V = ⅓ × (area of base) × (vertical height)
Area of the pyramid's square base = 144 m²
Volume = 384 m³
384 = ⅓ × 144 × (vertical height)
Vertical height = (3×384)/(144) = 8 m
But, the slant height of the square based pyramid forms a right angled triangle with the vertical height of the pyramid and the distance from the centre of the base of the pyramid to an edge of the pyramid.
The distance from the centre of the base of the pyramid to an edge of the pyramid = half of the length of the diagonal of the square base of the pyramid.
The diagonal of the square base of the pyramid also forms a right angled triangle with two sides of the square base of the pyramid.
Area of the square base of the pyramid = 144 m²
Area of a square = (side length)²
Side length = √(Area of the square) = √144 = 12 m
Using Pythagoras theorem,
(Length of the diagonal)² = 12² + 12² = 288
Length of the diagonal = (12√2) m
Half of the length of the diagonal of the square base = 6√2 m
Using Pythagoras theorem further
(Slant height of the pyramid)² = (vertical height of the pyramid)² + (Half of the length of the diagonal of the square base)²
(Slant height of the pyramid)² = 8² + (6√2)² = 64 + 72 = 136
Slant height of the pyramid = √136 = 11.66 m

A boy walks 40m from a city X on a bearing of 040° to a city Y. She then walks 40m on a bearing of 140° to a city Z. Find the bearing of Z from city X.
a) 35°
b) 50°
c)90°
Answers
Answer: option C.
Step-by-step explanation:
If city X is in the point (0,0)
Now, we can use that a displacement of L in distance with an angle A, gives us that the components of the displacement are:
X = L*cos(A)
Y = L*sin(A)
So we know that the city Y is located in:
(40m*cos(40°), 40m*sin(40°))
Now, from this point he moves other 40m with an angle of 140°.
The new position is
(40m*cos(40°) + 40m*cos(140°), 40m*sin(40°) + 40m*sin(140°))
this is:
40m*(cos(40°) + cos(140°), sin(40°) + sin(140°)) = 40m*( 0, 1.28)
the new position is (0, 51.2m)
This means that for a new displacement L and angle A we have:
X = L*cos(A) = 0
Y = L*sin(A) = 51.2m
Cos(A) is only 0 when A = 90° or 270°,
and we know that sin(90°) = 1 and sin(270°) = -1
As we have a positive number in the Y equation, we can conclude that A must be 90°.
Then
Y = L*sin(90°) = L = 51.2m
Here we finded that the bearing of Z from city X is 90°

A playground is located on a triangular piece of land. Two sides of the playground are 157 feet long and they meet at an angle of 65°. Your are hired to build a fence around the playground. Find the cost of the fencing material needed if it will cost $11.75 a foot.
Answers
Answer:
$5,671.84
Step-by-step explanation:
To find the third side, we can use the law of cosines:
c^2 = a^2 + b^2 - 2ab*cos(theta)
c^2 = 157^2 + 157^2 - 2*157*157*cos(65)
c^2 = 28463.7649
c = 168.71 feet
The perimeter of the playground is:
P = 157 + 157 + 168.71 = 482.71 feet
If each foot costs $11.75, the final cost is:
Cost = 482.71 * 11.75 = $5,671.84

The perimeter of a rectangle is 32 cm. If the width is 4 cm,find the length.
Answers
Answer:
it is 8
Step-by-step explanation:
Answer:
The length is 12cm
Step-by-step explanation:
The perimeter is the sum of all the sides
To work out the length of the rectangle you would first need to multiply the width of 4 by 2, this gives you 8. This is because the perimeter of the rectangle is the sum of all the sides, and as the rectangle has two sets of identical parallel lines.
The next step is to minus 8 from 32, this gives you 24. This is because we are isolating just the set of lengths.
The next step is to divide the value of 24 by 2, this gives you 12. This is because we had previously worked out what double the length is due to it being a set of parallel lines.
1) Multiply 4 by 2.
[tex]4*2=8cm[/tex]
2) Minus 8 from 32.
[tex]32-8=24cm[/tex]
3) Divide 24 by 2.
[tex]24/2=12cm[/tex]
Checking your answer:
To check your answer you would simply add the values of: 12, 12, 4, 4, and if this gives you 32 then the answer is correct.
1) Add 12 and 12 and 4 and 4.

Write an equation for an ellipse centered at the origin, which has foci at ( 0 , ± 24 ) (0,±24)left parenthesis, 0, comma, plus minus, 24, right parenthesis and co-vertices at ( ± 10 , 0 ) (±10,0)
Answers
Answer:
[tex]\frac{x^{2}}{400} + \frac{y^{2}}{976} = 1[/tex]
Step-by-step explanation:
The distance between foci with respect to origin is determined by mean of the Pythagorean Theorem:
[tex]2\cdot c = \sqrt{(0-0)^{2}+[24-(-24)]^{2}}[/tex]
[tex]2\cdot c = 48[/tex]
[tex]c = 24[/tex]
The distance between origin and any of the horizontal co-vertices is:
[tex]a = \sqrt{[10-(-10)]^{2}+(0-0)^{2}}[/tex]
[tex]a = 20[/tex]
Now, the distance between origin and any of the vertical co-vertices is determined by the following Pythagorean relationship:
[tex]c^{2} = b^{2} - a^{2}[/tex]
[tex]b^{2} = a^{2} + c^{2}[/tex]
[tex]b = \sqrt{a^{2}+c^{2}}[/tex]
[tex]b = \sqrt{20^{2}+ 24^{2}}[/tex]
[tex]b = 4\sqrt{61}[/tex]
Lastly, the equation of the ellipse in standard form is:

Sonji has $5.25 in nickels and dimes.The coin value can be modeled by the equation 0.10 d plus 0.05 n equals 5.25, where d represents the number of dimes and n represents the number of nickels. If Sonji has 21 dimes, how many nickels does she have?
Answers
Answer:
To find the number of nickels and dimes, we can use this equation: 0.10d + 0.05n = 5.25
We are given the information that Sonji has 21 dimes (which means that d=21). We can use the equation to find the number of nickels n.
0.10d + 0.05n = 5.25
0.10(21) + 0.05n = 5.25
2.10 + 0.05n = 5.25
0.05n = 3.15
n = 3.15 / 0.05
n = 315 / 5
n = 63
Sonji has 63 nickels.
Let's check our answer.
21(0.10) + 63(0.05) = 2.10 + 3.15 = 5.25
