find the exact value of the composite function show work
Answer:
[tex]\frac{2x}{\sqrt{4x^{2} -1} }[/tex]
Step-by-step explanation:
This function can be written as:
[tex]\frac{1}{cos(sin^{-1}(\frac{1}{2x})) }[/tex]
[tex]sin^{-1}(\frac{1}{2x})[/tex] means the angle whose sine is 1/(2x). This implies that the denominator is the cosine of the angle whose sine is 1/(2x)
Think of a right triangle and consider the angle with this sine. Then the opposite side has length 1 and the hypotenuse has length 2x. The Pythagorean theorem then implies that the adjacent side is
[tex]\sqrt{4x^{2} -1}[/tex]
The cosine of the angle is adjacent over hypotenuse, so the cosine is
[tex]\frac{\sqrt{4x^{2} -1}}{2x}[/tex]
The secant is the inverse of the cosine, so the answer is
[tex]\frac{2x}{\sqrt{4x^{2} -1} }[/tex]
Multiply the two polynomials and write your answer in standard form – 3x (4x - 2)
Answer:
-12x^2+6x
Step-by-step explanation:
-3x(4x-2)
-12x^2+6x
The standard form of the polynomial is -12x² +6x.
What is a polynomial?A polynomial is an equation made up of exponents, constants, and variables that is combined using mathematical operations including addition, subtraction, multiplication, and division.
The given expression is – 3x (4x - 2)
Solving further,
–3x (4x - 2)
=-12x² +6x.
The standard form of the polynomial is -12x² +6x after multiplying – 3x (4x - 2)

A donut shop made 32 donuts with frosting and 18 donuts without frosting. What is the ratio of the number of donuts with frosting to the number of donuts without frosting?
Answer:
16 to 9
Step-by-step explanation:
Represent donut with frosting with D1 and donut without frosting with D2.
So, we have:
[tex]D_1 = 32[/tex]
[tex]D_2 = 18[/tex]
Required
Find the ratio of D1 to D2
This is calculated as:
[tex]D_1 : D_2[/tex]
Substitute values for D1 and D2
[tex]D_1 : D_2 = 32 : 18[/tex]
Divide by 2
[tex]D_1 : D_2 = 32/2 : 18/2[/tex]
[tex]D_1 : D_2 = 16 : 9[/tex]
The ratio of donuts with frosting to donuts without is 16 to 9
Answer:
16 to 19

Maggie says that if the expression was 12÷3to the second power, you would divide before simplifying 3 to the second power. Is she right? Explain
Answer:
Maggie is incorrect.
Step-by-step explanation:
PEMDAS tells us the order of operations and the steps of solving a mathematical statement. It states that exponents must be performed before multiplication or division.
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Therefore, to solve 12÷3² correctly, 3² needs to be simplified to 9 before dividing.
I hope this helps!

pls help me ASAP!! what is the surface area of this design? a) 288in b) 256in c) 96in d) 160in
Answer:
b) 256 inches
Step-by-step explanation:
8x5x2 = 80 (top & bottom)
8x5x2 = 80 (front & back)
8x8x2 = 128 (gross area of 2 sides)
4x4x2 =32 (delete this for side cutouts) Guessing the cutoff dimension on
left side is 4m inch.
80+80+128-32 = 256 inches
Combine any like terms in the expression. If there are no like terms, rewrite the expression.
6pg + 5pg - 6pg
Answer: I believe the answer is just 5pg?
Step-by-step explanation: Hope this helps but sorry if it's wrong. Not sure if I'm understanding the question correctly.
Answer: 5pg
Step-by-step explanation:
Like terms are terms that have the same variables and powers. E.g. 8p²g+9p²g=17p²g
8+9=17
8pg+9pg=17pg
8pg²+9pg²=17pg²
How to work out the question:
6pg+5pg=11pg
11pg-6pg=5pg

Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How much will Colin have after 10 years to the nearest pound?
help quickly
Answer:
£3692
Step-by-step explanation:
A = p(1 + r/n)^nt
Where,
A = future value
P = principal = £2350
r = interest rate = 4.2% = 0.042
n = number of periods = 1(annual)
t = time = 4 years
A = p(1 + r/n)^nt
= 2350(1 + 0.042/1)^1*4
= 2350(1 + 0.042)^4
= 2350(1.042)^4
= 2350(1.5789)
= 2770.42
A = £2770.42
Total years = 10
Remaining years = 10 - 4
= 6 years
Remaining 6 years
P = £2770.42
r = 4.9% = 0.049
n = 1
t = 6
A = p(1 + r/n)^nt
= 2770.42(1 + 0.049/1)^1*6
= 2770.42(1 + 0.049)^6
= 2770.42(1.049)^6
= 2770.42(1.3325)
= 3691.59
A = £3691.59
Approximately £3692

Tell whether (4, 27) is a solution of y=3x+15
Answer:
Yes
Step-by-step explanation:
We have two properties for our question :
(4, 27)
y = 3x + 15
We are being asked whether the point (4, 27) is a solution of y = 3x + 15
So how do we figure this out? Well, what we have to know first that (4, 27) represents a variable, 4 which is the run on the graph, represents x in a solution. And 27 which is the rise on the graph, represents y in the solution. So when asking for a solution with two points, all we must do is substitute x and y for the two coordinates.
y = 3x + 15
y = 27 and x = 4
27 = 3(4) + 15
27 = 12 + 15
27 = 27
Since this equation is true with the respected variables, therefore signifies that (4,27) is a solution of y = 3x + 15
