Step-by-step explanation:
First get rid of log (3), toss it over exuation sign.
Then calculate the formula for double angle (sin 2x = sin²X + sin(X) x cos (X) + cos²X)
After you do that you should be able to divide everything with cos²X and get polynomial exuation which is solved by substitution method (you'll get tan and then switch it for lets say letter: t

Find an equation of a line that is parallel to y = 5x - 21 and passes through the point (3, 7)
Answer:
y=5x-8 is the parallel line that passes through the point (3,7)
Step-by-step explanation:
Find the slope of the original line and use the point-slope formula y-y₁=m(x-x₁) to find the parallel line to y=5x-21, which if done correctly you should end up with y=5x-8
hope this helps!
A line with a slope of 0 passes through the points (–4,q) and (6,–10). What is the value of q?
Answer:
q = - 10
Step-by-step explanation:
A line with a slope of zero is a horizontal line parallel to the x- axis
The y- coordinates of the points the line passes through are equal
Given the line passes through (- 4, q) and (6, - 10 ) with y- coordinate - 10
Then q = - 10

Write the equation in standard form for the circle x2 + 32 = -y² + 12x.
Step-by-step explanation:
Move
26
to the right side of the equation because it does not contain a variable.
3x2−12x−2y2+16y=26
Answer:
(x - 6)² + y² = 4
Step-by-step explanation:
x² + 32 = -y² + 12x
Rearrange
x² - 12x + y² = -32
Complete the square for x
(x - 6)² + y² = -32 + (-6)²
(x - 6)² + y² = -32 + 36
(x - 6)² + y² = 4
what is an expression showing the sum of 5 less than the number k
Answer:
5<k
Step-by-step explanation:
Answer:
k-5
Step-by-step explanation:
So, lets go over each part of the sentence, and turn it into a expression.
So it first says sum. This means addition, so we can start our expression with:
+
Next is says of 5. So we know its the addition of 5:
+5
Next it says less than. So now we know less than, which is subtraction. So we can swap the addition sign for a - sign:
-5
Finally it says the number k. So we know that the subtracted value is k:
k-5
So this is your expression!
Hope this helps!
If n is an even number, find the next consecutive even number.
Answer:
n+2 is the next even number as n is an even number so adding 2 will make it an even number again.

nich colour of car did Jay record most often?
Answer:
The correct answer is -
1. An image with correct tally marks and frequency values is attached.
2. Silver
Step-by-step explanation:
The given data of different color cars that going past his house one morning is given in 20 times. The frequency of each car is -
Blue cars - 4 times out of 20
red - 6 times out of 20
silver - 8 times out of 20
black - 2 times out of 20
The complete table is attached as an image -
2. the maximum frequency of the car is the silver car so Jay must have recorded the silver car most often.
Bart is collecting data on sunflower growth. He records the height, in inches, of his sunflower each day. Which best describes the type of data Bart is collecting
Answer:
Numerical data
Step-by-step explanation:
Given
Height recorded on a bar chart
Required
The type of data
From the question, we understand that the height is being recorded.
Height of flowers are numbers (e.g. 6in, 5in. 3in etc.).
When data are presented in numbers (i.e. digits), such data are referred to as numerical data.
Taxi company A charges $4 plus $2 per mile. Taxi company B charges $5 plus $3 per mile. Which system best represents this problem?
y = 4 x + 0 . 5 , y = 5x + 0.25
y = 4 + 2x , y = 5+3x
y = 4 x + 1 5 , y = 15x + 2
y = - 0 . 5 x + 4 , y = -0.25x + 5
Answer:
The second option
Step-by-step explanation:
To solve this, you should convert both rates to equations, with y being the total fare, and x being the number of miles. The rates of both use the format y=mx+b (where m is the amount per mile and b is the flat rate, or original rate).
By subbing in the values for m and b, you get y=2x+4 for A and y=3x+5 for B. This is the second option.

What is the axis of symmetry for the function f(x)=7−4x+x2?
x = –3
x = –2
x = 2
x = 3
Answer:
Answer:
x = 2
Step-by-step explanation:
The vertex form of the parabola is given by
Comparing this equation with vertex form of a parabola , where (h,k) is the vertex
h = 2
k = 3
Hence, vertex is (2,3)
Now, axis of symmetry of a parabola passes through the vertex and divide the parabola in two equal halves.
Hence, axis of symmetry of the parabola is given by
x = h
x = 2
Third option is correct.

If x = 2 and t = 4, what is the value of 2(x3 – 4)(t2 + 8)
Answer:
64
Step-by-step explanation:
Just add in the numbers and put the expression into a calculator.
Match each power of a power expression with its simplified expression
= 4⁰×-⁹
= 4⁰
(-4⁹)²= -4⁹ײ
= -4¹⁸
=( -4)¹⁸
(4-³)-³= 4-³ × -³
= 4⁹
(4⁶)-³= 4⁶ × -³
= 4-¹⁸
= 1/4¹⁸
The straight line 3x + 4y = 24 cuts the y - axis at the point A and cuts the x - axis at the point B. What is the distance AB?
Step-by-step explanation:
the answer is in the above image
The distance between point A and point B is 10 units.
What is the distance between two points on a plane?The distance between two points on a coordinate plane (x, y) and (x, y) is
= √[(x₂ - x₁)² + (y₂ - y₁)²] units
The given straight line is 3x + 4y = 24.
This straight line will cut the x-axis at a point where y = 0.
Therefore, 3x + 4(0) = 24
⇒ 3x = 24
⇒ x = 8
Therefore, the coordinates of the point A is (8, 0).
Similarly, this straight line will cut the y-axis at a point where x = 0.
Therefore, 3(0) + 4y = 24
⇒ 4y = 24
⇒ y = 6
Therefore, the coordinates of the point B is (0, 6).
Therefore, the distance between point A and point B is
= √[(0 - 8)² + (6 - 0)²] units
= √(64 + 36) units
= √100 units
= 10 units (negative sign is avoided.)
