Answer:
Animism
Step-by-step explanation:
Animism is often a major idea or thought which is developed in a child preooperational stage according to paiget's theory of cognitive development where a child's learning is driven and derived from by symbols. At this stage, a child often relates with their toys, and other inanimate objects they come across as though they were real, manipulating and transforming them to form different things including relating with these manipulated objects like they were living. This is because at this stage, a child cannot use cognitive or logic to make distinctions.

Find the sum of the following series. Round to the nearest hundredth if necessary,
3 + 6 + 12+ ... +49152
Sum of a finite geometric series:
Q] - a
Sn =
1-T
Answer:
[tex]sum = \frac{a( {r}^{n - 1} )}{r - 1} \\ : but \: l = a( {r}^{n - 1} ) \\ 49152 = 3( {2}^{n - 1} ) \\ 16384 = {2}^{n - 1} \\ {2}^{n} = 32768 \\ {2}^{n} = {2}^{15} \\ n = 15 \\ \therefore \: sum = \frac{3(2 {}^{15 - 1}) }{15 - 1} \\ = \frac{49152}{14} \\ = 3510.9[/tex]

Answer:
1583.4 ft³
Step-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr²h
The radius is half the diameter, so is (12 ft)/2 = 6 ft. Then the volume is ...
V = π(6 ft)²(14 ft) ≈ 1583.4 ft³
_____
Additional comment
The number shown in the problem statement answer box is the number you would get using the diameter in the above formula instead of the radius.
The volume of cylinder is 1583.4ft³.
Step-by-step explanation:
Given that :-
Height of cylinder = 14 ftBase diameter if cylinder = 12 ft
so, Radius of cylinder, r = 12 / 2 = 6 ftTo find :-
Volume of cylinderSolution :-
Using formula
Volume of cylinder = π × r² × h
Substitute the value
Volume of cylinder = π × (6ft)² × 14 ft
evaluate the exponent
Volume of cylinder = π × 36 ft ² × 14ft
multiply
Volume of cylinder = π × 504 ft³
Using , π = 3.14
Volume of cylinder = 3.14 × 504 ft³
Hence, the volume of cylinder is 1582.56ft³.
Round nearest tenth place = 1583.4 ft³.

Answers:
a = 1/3
b = -6
c = 7
======================================================
Explanation:
The terms of the given expression rearrange to [tex]\frac{1}{3}x^2 - 6x+7[/tex] which is now in standard form (the exponents decrease when moving from left to right).
We can see that
a = 1/3
b = -6
c = 7
after matching that with the ax^2+bx+c form.

Step-by-step explanation:
What is the greatest common factor of 4 - 6а?
Answer:
GCF (4 ,6) = 2
Greatest common factor (GCF)
Step-by-step explanation:
Find the area of each figure. Use 3.14
===============================================================
Explanation:
The top and bottom semicircles can be joined to form a full circle. The same can be said about the left and right semicircles. Each circle has diameter 3 and radius 1.5
The area of one circle is
A = pi*r^2
A = 3.14*(1.5)^2
A = 7.065
So two circles doubles to 2*7.065 = 14.13 square meters in area.
Then the last step is to add on the area of the 3 by 3 square (area 3*3 = 9) to get 14.13+9 = 23.13
This area is approximate because pi = 3.14 is approximate. Use more decimal digits in pi to get a more accurate area. However, your teacher wants you to use this specific value so it's best to stick with 23.13
Answer:
23.14
Step-by-step explanation:
The shape is basically two equal-sized circles and a square.
Find the area of the square: 3 x 3 = 9
9 is the area of the square
The formula for finding the area of a circle is pi x radius squared.
3.14 x 1.5 squared = 7.06858
Round to 7.07 and multiply by 2 = 14.14
14.14 (area of both circles) + 9 (area of square) = 23.14

Which choice represents the simplified exponential expression?
(8^7)^5
Answer:
8^35
you multiply exponents of exponents meaning we multiply 7*5 which is 35
Step-by-step explanation:
If m and n are two natural number and m^n =8,then n^mn is.
Answer:
729
Step-by-step explanation:
M has to be 2 and n has to be 3, because 2^3 = 8
if it was 3^2 it would be 9
2^3 = 8
3^(2*3) = 3^6 = 729

A ladder that is 20 feet long leans against the wall of a building such that its base makes a 62 degree angle with the ground. Determine the height, h, that the ladder reaches up the wall. Round your answer to the nearest tenth of a foot.
Answer:
17.7 ft
Step-by-step explanation:
A ladder that is 20 feet long leans against the wall of a building such that its base makes a 62 degree angle with the ground. Determine the height, h, that the ladder reaches up the wall. Round your answer to the nearest tenth of a foot.
We solve using the Trigonometric function of sin
sin = Opposite/Hypotenuse
Opposite = Height = ?
Hypotenuse = Length of the ladder = 20 ft
Hence:
sin 62 = h/20 ft
Cross Multiply
h = sin 62 × 20 ft
h = 17.658951857 ft
Approximately = 17.7 ft

What should be the first step in adding these equations to eliminate y?
Answer:
D
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Since you want to eliminate y, the y value on the bottom equation has the be the opposite of the y value on the top one. So it's 4y on the top one, so the bottom one has to be -4y to eliminate y. The bottom one is -2y, so -2 times 2 =-4, so multiply the bottom one by 2 omg i miss linear combination

help w this questionn ^^
Answer:
BC = 8 cm
Step-by-step explanation:
tan(x) = sin(x)/cos(x)
sin(x) is the opposite side of the angle x.
cos(x) is the side with a right angle to sin(x).
2 = 12/EC
EC = 12/2 = 6 cm
=>
CD = ED - EC = 10 - 6 = 4 cm
now, the same tan(x) relation had to be true for BCD.
tan(x) = BC/CD
2 = BC/4
BC = 8 cm
