To Write Equations of Parallel or perpendicular Lines Write the equation of the line that is parallel to y=2x + 4 and passes through the point (-4,-1). Geometry question
Answers
Answer:
Equations of parallel and perpendicular lines The equation of a straight line is represented as \ (y=ax+b\) which defines the slope and the \ (y\)-intercept. Here \ (a\) represents the slope of the line. Since two parallel lines never intersect and have the same slope, their slope is always equal.

1. a. The image's dilated side lengths on each side:
AB = CD = 45cm.
BD = AC = 24cm.
2. a. Equal ratios exist between the lengths of matching sides. The ratio is the same as the dilation's scale factor.
b. The image is a dilation of the original image.
c. The scale factor = 4.
3. a. The image is a dilation of the original image.
b. The scale factor = 2.
What do you mean by scale factor?A scale factor, often referred to as a conversion factor, is a numerical value that is used to alter a figure's size without altering its shape. The scale factor can be calculated if both the dimensions of the original and the dilated (increased or lowered) figure are known. The basic formula for calculating a figure's scale factor is given as,
Scale factor is equal to the division between the dimensions of the new and old shapes.
In the first figure, the sides are given as:
AB = 15cm
BD = 8cm
Scale factor = 3
Now, using the scale factor formula:
Scale factor = New dimensions/Old dimensions
⇒ 3 = New dimension/15
⇒ New dimension of AB = 45cm.
Similarly, new dimension of BD = 24cm.
In the second figure, as the lengths of corresponding sides have equal ratios. Both the figures are similar. The image is the dilation of the original figure as the lengths of corresponding sides have equal ratios. The ratio is the same as the dilation's scale factor. So, the scaler factor here is 4.
Now in the last figure we can see that the coordinates of A', B', C' and D' are exactly half of that of the coordinates of A, B, C and D.
The ratio of the coordinates is 2:1.
Therefore, the scale factor = 2.

What is the answer for x?
Answers
Answer:
x = 7°
Step-by-step explanation:
Sum of All angles = 180°
Form an equation
180 - 90 - 36 = 7x + 5
54 = 7x + 5
Subtract 5 from both sides
49 = 7x
x = 49/7
x = 7

The sides of a triangle are in the extended ratio of 3 : 4:10. If the length of the
shortest side is 9 in., what is the perimeter of the triangle?
Answers
Answer:
51cm
Step-by-step explanation:
9 divided by 3 is 3inches
3 inches is 1 share
3 plus 4 plus 10 is 17
17 times 3 is 51
The length of the triangle is 9, 12, and 30. Then the perimeter of the triangle will be 51 inches.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
The perimeter of the triangle is determined by adding together all of its sides.
The sides of a triangle are in the extended ratio of 3:4:10. If the length of the shortest side is 9 in.
Let x be the canceled value from the ratio. Then we have the ratio will be 3x: 4x: 10x.
The value of the variable 'x' is given as,
3x = 9
x = 9 / 3
x = 3
Then the other sides of the triangle will be
4x = 4 (3) = 12 in
10x = 10 (3) = 30 in
Then the perimeter of the triangle will be calculated as,
P = 9 + 12 + 30
P = 51 inches
The length of the triangle is 9, 12, and 30. Then the perimeter of the triangle will be 51 inches.

Bacteria are the most common example of exponential growth. Select a number between 2 and 10 to represent the hourly growth rate of a certain bacteria. For example, selecting the number 8 would mean that the amount of bacteria will be 8 times greater after every hour.
a. Suppose you start with one single bacterium. Make a table of values showing the number of bacteria that will be present after each hour for the first six hours using the hourly growth rate that you selected. Then determine how many bacteria will be present once 24 hours have passed.
b. Explain why this table represents exponential growth.
c. Using this example, explain why any nonzero number raised to a power of zero is equal to one.
d. Write a rule for this table.
e. Suppose you started with 100 bacteria, but they still grew by the same growth factor. How would your rule change? Explain your answer.

Answers are below
Step-by-step explanation:
Hour 0 1 bacterium
Hour 1 3 bacterium
Hour 2 9 bacterium
Hour 3 27 bacterium
Hour 4 81 bacterium
Hour 5 243 bacterium
Hour 6 729 bacterium
After 24 hours, the number of the bacterium will reach 282,429,536,481.
B) This table represents exponential growth because of the number of bacterium always being multiplied by 3.
C) The reason that any number to the zero power is one is that any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1.
D) Y = 1 + 3 to the power of x
E) The rule would change by having all of the numbers multiplied by 100 since there is 100 bacterium at Hour 0.

Remember SOH CAH TOA? Well, we have the adjacent and opposite sides involved in this, so we use the tangent function!

What is Square Root?Square root of a number is the value such that the value when multiplied to itself two times gives the original number.
It is denoted by the symbol √.
For example, square root of 16 is 4 since 4 × 4 = 16
Given expression is
√100 / √25
We have to find the square root of each of the value and then divide it.
We know that,
100 = 10 × 10
So 100 = 10²
So,√100 = 10
Similarly,
25 = 5 × 5
So √25 = 5
Substituting the values,
√100 / √25 = 10 / 5 = 2
Hence the quotient is 2.
