Step-by-step explanation:
Answer:
X = 5
Step-by-step explanation:
Input the y into the equation:

b= 13 ft. 6 in.
h= 10 ft. 3 in.
Answer:
A=19,926in.
or
A=1660.5ft
Step-by-step explanation:
you convert the feet into inches which gives you a base of 162 inches and a height of 123 inches. Next you multiply your base and height and it gives you an Area of 19,926inches but then if you need to convert the inches back into feet by dividing 19,926 by 12. After you do that you should end up with an area of 1660.5 feet.
e =
=
5e + 3f = -36
-e + 2f = 2
f = 1
Answer:
e = -6
f = -2
Step-by-step explanation:
I used the elimination method and multiplied the second equation by 5 to get:
-5e + 10f = 10. Added this to:
+ 5e + 3f = -36
13f = -26
f = -2
now find e: -e - 4 = 2
-e = 6
e = -6

Find f(g(3)) given:
*
f (x) = 2x2 – 1
g(x) = 3x
h(x) =
j(x) = x - 5
Answer:
161
Step-by-step explanation:
Given the functions
f (x) = 2x^2 – 1
g(x) = 3x
we are to find f(g(3))
First look for the composite function f(g(x))
f(g(x)) = f(3x)
f(3x) = 2(3x)² - 1
f(3x) = 2*9x² - 1
f(3x) = 18x² - 1
f(g(x)) = 18x² - 1
Substitute x = 3 into the result
f(g(3)) = 18(3)² - 1
f(g(3)) = 18*9- 1
f(g(3)) = 162-1
f(g(3)) = 161
Hence f(g(3)) is 161

1 Jesy invests £8000 for n years in a savings account.
To find the value, V, of her investment after n years she uses the formula:
V = 8000 × (1.025)n
(a) Write down the annual rate of interest Jesy earns.
(b) Find the total amount of interest Jesy earns in three years.
(Total for question 1 is 3 marks)
Answer:
2.5% , $8608
Step-by-step explanation:
Given data
From the given the expression V = 8000×(1.025)^n
The rate is given as
2.5%
For n= 3
The total amount is
V = 8000 × (1.025)^3
V= 8000*1.076
V= $8608
Hence the final amount is $8608

Step-by-step explanation:
AB is a straight line.
Work out the size of angle x.
Not drawn accurately
(132
Х
A
B
x:48
A straight line will be 180 degrees so 180－132＝x
132＋48=180
The value of the angle x will be 48° hence correct option will be 48°.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
Given that a line with an angle of 132° since in a single line has an angle of 180° so
Angle x + 132° = 180°
x = 180° - 132° = 48° hence it will be the correct answer.

Use the information below for Part A, Part B, and Part C.
f(x) = 1/2x -7
g(x) = 2x + 14
Part A: Find (fog)(x). Show your work.
Part B: Find (gºf)(x). Show your work.
Part C: Use your answers to Part A and Part B to determine whether the two functions are inverses. Explain your answer fully.
Answer:
(1/2(2x+14)-7) = 1x+7-7= x g(f(x))= 2(1/2x-7)+14= x-14+14= xWe have the result being two variables of linearity hence they are not inverses. In order to be inverses they should have had switched notations, ie: -x vs x9514 1404 393
Answer:
A: (f∘g)(x) = x
B: (g∘f)(x) = x
C: the functions are inverses
Step-by-step explanation:
A: (f∘g)(x) = f(g(x)) = f(2x +14)
= 1/2(2x +14) -7 = x +7 -7 = x
(f∘g)(x) = x
__
B: (g∘f)(x) = g(f(x)) = g(1/2x -7)
= 2(1/2x -7) +14 = x -14 +14 = x
(g∘f)(x) = x
__
C: When a function is operated on by its inverse, then original argument value is restored. That is the case for functions f and g, so the two functions are inverses.

Can someone help me find out what’s the nth formula equation
An example is where it should look like 6•5^n-1
Or 7n-4 (that’s an example) if it’s correct I’ll mark u brainiest.
Part (a)
This sequence is arithmetic because we are adding 4 to each term to get the next term. Nice work on getting the correct answer here.
To get the nth term of an arithmetic sequence, we'll use the formula below
an = a + d(n-1)
In this case, a = 14 is the first term and d = 4 is the common difference
So we have these steps
an = a + d(n-1)
an = 14 + 4(n-1)
an = 14 + 4n - 4
an = 4n + 10
Answer: 4n + 10
============================================
Part (b)
This sequence is geometric since we multiply each term by 4
The common ratio is r = 4 and the start term is a = 2.
So the nth term is....
an = a*(r)^(n-1)
an = 2*(4)^(n-1)
Answer: 2*(4)^(n-1)

A supplementary angle has three angles one being 44.4 another being 7x and another is 8x. I'm having a hard time.
Answer:
x= 9.04°
7x = 63.28°
8x = 72.32
44.4° + 63.28° + 72.32° = 180°
Step-by-step explanation:
The sum of supplementary angles is 180°
Set up an equation with the given information, then solve for x.
44.4 + 7x + 8x = 180
7x +8x = 180-44.4
15x = 135.6 Divide both sides by 15
x = 9.04

Answer:
a. m<DAB = 36°
b. m<B = 54°
c. m<C = 74°
Step-by-step explanation:
a. m<DAB = m<CAB + m<CAD
m<DAB = 20° + 16° (substitution)
m<DAB = 36°
b. m<B = 180° - (90° + m<DAB)
m<B = 180° - (90° + 36°) (substitution)
m<B = 54°
c. m<C = 180° - (90° + m<CAD)
m<C = 180° - (90° + 16°) (substitution)
m<C = 74°

Maggie is trying to find the best deal to buy bags of potato chips. Option A: $0.90 for 9 bags of chips Option B: $0.84 for 7 bags of chips Option C: $1.50 for 5 bags of chips Which option is the better deal?
A
Option A
B
Option B
C
Option C
Answer:
The answer is option A. Since you would be paying 0.10 for each bag.
The solution is Option A.
The best deal for Maggie to buy the bag of potato chips would be 9 bags for $ 0.90 because each bag cost $ 0.10
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of each bag be represented as A
Now , the equation will be
a)
$0.90 for 9 bags of chips
The cost of 9 bags = $ 0.90
The cost of 1 bag A = The cost of 9 bags / 9
Substituting the values in the equation , we get
The cost of 1 bag A = 0.90 / 9
On simplifying the equation , we get
The cost of 1 bag A = $ 0.10
b)
$0.84 for 7 bags of chips
The cost of 7 bags = $ 0.84
The cost of 1 bag A = The cost of 7 bags / 7
Substituting the values in the equation , we get
The cost of 1 bag A = 0.84 / 7
On simplifying the equation , we get
The cost of 1 bag A = $ 0.12
c)
$1.50 for 5 bags of chips
The cost of 5 bags = $ 1.50
The cost of 1 bag A = The cost of 5 bags / 5
Substituting the values in the equation , we get
The cost of 1 bag A = 1.50 / 5
On simplifying the equation , we get
The cost of 1 bag A = $ 0.30
Therefore , the 0.10 < 0.12 < 0.30
Hence , the cost of $0.90 for 9 bags of chips is the best deal
