Answer:
The student forgot about the double angle identity.
Step-by-step explanation:
sin2x/cosx=2
This is the double angle identity
sin2x=2sin(x)cos(x)
(2sinxcosx)/cosx=2
2sinx=2
sinx=1
x=sin^-1(1)
x=90 degrees OR pi/4

A 4-story building is 29 feet tall. Between which two whole numbers does the height of each story lie?
Answer:
7 & 8
Step-by-step explanation:
29÷4=7.25
7<7•25<8
The inequality of the height of the building is given by 7 < A < 8 , where A is the height of the building = 7.25 feet
Given data ,
A 4-story building is 29 feet tall
So , the height of the each story is given by the equation ,
To determine the height of each story in a 4-story building, we divide the total height of the building (29 feet) by the number of stories (4).
A = 29/4
On simplifying the equation , we get
29 feet ÷ 4 stories = 7.25 feet per story
Now , the inequality representing the height of the building between the whole numbers is given by
7.25 lies between 7 and 8
So , the inequality is 7 < A < 8
Hence , the height of each story in the 4-story building lies between 7 feet and 8 feet

Answer:
D
Step-by-step explanation:
Answer:
[tex]\boxed {\boxed {\sf D. \ 64x^{12}y^6z^2}}[/tex]
Step-by-step explanation:
This is an example of a power to a power. The exponents inside the parentheses are being raised to another power outside the parentheses. We multiply the exponents and take the coefficients (number in front of the variables) to the power.
[tex](8x^6y^3z)^2[/tex]
Remember that a variable without an exponent has an implied exponent of 1.
[tex]8^2x^{6*2}y^{3*2}z^{1*2}[/tex]
Solve the coefficient's exponent.
8²= 8*8= 64[tex]64x^{6*2}y^{3*2}z^{1*2}[/tex]
Multiply the exponents.
[tex]64x^{12}y^{6}z^{2}[/tex]
So, the expression given is equal to Choice D: 64x¹²y⁶z²

Simplify: 14ba2+21ab2−ab2.
The given expression 14ba²+21ab²−ab² can be simplified to 14ba²+20ab².
What is simplification?In arithmetic, the operation and interpretation of a function to make it simpler or easier to grasp is known as simplifying, and the process itself is known as simplification.
The expression is given in the question, as follows:
14ba²+21ab²−ab²
When you add or subtract similar terms, you can combine their coefficients. In this case, 21ab² and -ab² have the same base (ab²) and so their coefficients can be added together. 21 - 1 = 20, so 21ab² - ab² = 20ab².
Thus, the given expression can be simplified to 14ba²+20ab².
