Answer:
12)5^x=125
13)5
Step-by-step explanation:
The base on the logarithm is also the base of the exponent so 5^something=something else and 125 is the number in the logarithm it is put on the other side so 5^something=125 and as the something is x the answer is 5^x=125
The second question uses the same logic 2^y=32 so y must be 5

Can a parallelogram have more than 3 lines of symmetry?
Answers
Answer:
no
Step-by-step explanation:
Parallelograms have zero lines of symmetry because it is impossible to draw a line through the center of any parallelogram that divides the figure into two equal halves that are mirror images of each other.
Answer:
Technical answer no
BUT
if you are in a college/postgraduate level group theory class yes
Step-by-step explanation:
Imagine a square, and imagine 4 lines across the top, the side, and the two diagonal ones. Because the two diagonal lines of symmetry are technically the same, there are only three possible lines.
if you are in the group theory class, comment and ill give a lengthy answer on that.

The image represents a rectangular patio that has a length equal to 4 feet more than the width. What is the perimeter of the patio?
Answers
Answer:
4w+8 feet
Step-by-step explanation:
The perimeter of a rectangle is the sum of the lengths of its sides. Since opposite sides are identical in length, it can be computed as double the sum of adjacent side lengths. Here, the lengths are in feet.
P = 2(L+W)
P = 2((w+4) +w)
P = 4w +8
The perimeter of the patio is 4w+8 feet.
If two opposite sides of a square are increased by 15 meters and the other sides are decreased by 13 meters, the area of the rectangle that is formed is 60 square meters. find the area of the original square.
Answers
Answer: Shown below
Step-by-step explanation:
Since it's a square, we will refer to its values as x. Using that, we can make an equation for the rectangle.
(x + 15) * ( x - 13) = 60
We can expand it and simplify so that we get a zero on one side and a polynomial on the other.
(x + 15)(x - 13) - 60 = 0
x² + 2x - 225 = 0
We simplify the binomial so we get two answers for x.
(x - 15)(x + 17) = 0
x = 15 and -17
Now we have two answers. So which one is right? Well, the sides cannot be negative, therefore we must use 15 and not -17.
15² = 225
Our answer is 225

Find cos (B) in the triangle
Answers
We can identify the sides of a right triangle by describing their location in relation to a given angle.
The "hypotenuse" is the longest side of a right triangle. It is opposite the right angle.The "opposite" is the side that the angle does not touch.The "adjacent" is the side that the angle does touch, that is not the hypotenuse.There are three basic trigonometric ratios:
The sine ratio: [tex]\sin\theta=\dfrac{opposite}{hypotenuse}[/tex]The cosine ratio: [tex]\cos\theta=\dfrac{adjacent}{hypotenuse}[/tex]The tangent ratio: [tex]\tan\theta=\dfrac{opposite}{adjacent}[/tex]We use theta (θ) to represent an angle.
Solving the QuestionWe are asked to find [tex]\cos(\beta)[/tex] in the triangle.
[tex]\cos\theta=\dfrac{adjacent}{hypotenuse}[/tex]
The side adjacent to β measures 8 units.
The hypotenuse of the right triangle measures 17 units.
[tex]\cos\beta=\dfrac{8}{17}[/tex]
AnswerTherefore, [tex]\cos\beta=\dfrac{8}{17}[/tex].

A triangle has one side measuring 16 inches and two sides measuring 13 inches. Is this triangle scalene?
yes
no
Answers
No, because a scalene triangle has to have all sides that are different lengths. 2 sides being 13 inches would mean that the triangle has 2 sides that are equal, making it an isosceles triangle.
Answer:
no
Step-by-step explanation:
A triangle is scalene when its sides have three different lengths. Your triangle has two sides with the same measure, so it is isosceles, not scalene.

C. -7x - 5y = -48
D. 7x - 5y = 48
Answers
Answer:
(C) -7x - 5y = -48
Step by step explanation:
We look for the equation of the line AB
We have then:
y-yo = m (x-x0)
m = (y2-y1) / (x2-x1)
m = (4 - (- 1)) / (4 - (- 3))
m = 5/7
We choose an ordered pair:
(xo, yo) = (4, 4)
Substituting:
y-4 = (5/7) (x-4)
y = (5/7) x-20/7 + 4
7y = 5x - 20 + 28
7y = 5x + 8
y = (5/7) x + 8/7
The equation of the perpendicular line is:
-7x - 5y = -48

The world population is projected to be 8.2 billion in 2045. At that time, there are expected to be approximately 3 billion more people in Asia than in Africa. The population for the rest of the world will be approximately 0.2 billion more than half the population of Asia. Find the projected populations of Asia, Africa, and the rest of the world in 2045.
The projected population of Asia will be approximately billion
Answers
Answer:
Since the total population will be 9.4B people
W + A+ A =9.4B
W = 0.6B + A/4
A+ 2.9B = As
A - 2.9B + As + 0.6 + A/4 = 9.4B
(9/4)*A= 11.7B
A = (4/9)*11.7B=5.2B
W = 0.6B + (5.2B/4) = 1.9B
A = 5.2B - 2.9B = 2.3B

Find f(h(-1)).

Answers
Answer:
f(h(-1)) = - 11 or D
Step-by-step explanation:
h(-1) = -2(-1)^2 - 3(-1) + 1
h(-1) = -2(1) + 3 + 1
h(-1) = 2
f(2) = (2t + 7)/(t - 3)
f(2) = (2*2 + 7) / (2 - 3)
f(2) = 11/-1
f(2) = - 11
Be very careful how you handle this. The way I have done it will work, but it does not work all the time.
The sure way to handle this is to put(h(n)) every place you can on the right side of f(t)
f(h(n)) = (2(h(n) + 7)) / (h(n) - 3)
