The value of the expression is 1.Six consecutive numbers add up to a total of 69. What is the highest of these numbers.
Answer:
consecutive numbers = 9,10,11,12,13,14
highest of these numbers = 14
Step-by-step explanation:
the six consecutive numbers are
9+10+11+12+13+14
= 19 +11+12+13+14
= 30 +12+13+14
= 42+13+14
= 55+14
= 69
highest of these numbers = 14

If f(x) = 25 + 4 x + 15 and g(x) = 2x2 + 47, compute the composition (f ∘ g)(1). (f ∘ g)(1) =
A composite function is the combination of two or more functions to create another function. The value of (f o g)(1) is 126
Given that:
[tex]f(x) = 2x^2 + 4x + 15[/tex]
[tex]g(x) = 2x^2 + 4x[/tex]
[tex](f\ o\ g)(x)[/tex] is calculated as:
[tex](f\ o\ g)(x) = f(x) \times g(x)[/tex]
So, we have:
[tex](f\ o\ g)(x) = (2x^2 + 4x + 15) \times (2x^2 + 4x)[/tex]
Substitute 1 for x
[tex](f\ o\ g)(1) = (2 \times 1^2 + 4 \times 1 + 15) \times (2 \times 1^2 + 4 \times 1)[/tex]
[tex](f\ o\ g)(1) = (21) \times (6)[/tex]
[tex](f\ o\ g)(1) = 126[/tex]
Hence, the value of (f o g)(1) is 126

1. Amber works at the doggy daycare after school.
A. Use the information in the photograph to complete the table and make a graph of the data.
B. Is the relationship between the amount Amber earned any number of hours a proportional relationship?
Explain.
C. What point represents the constant of proportionality?
D. What is the ratio y/x for each point on the graph?
please help me
no links or files
thank you !
A.)
From the table ;
We could deduce, that the value of y increases as x increases : this could mean a direct variation :
y α x
y = kx
k = constant of proportionality
k = y/x
Missing value of x in the table could be inferred to be 4
Find k., when x = 4 and y = 32
k = 32/4
k = 8
Hence :
Values of y :
For x = 1
y = 8 × 1 = 8
For x = 2
y = 8 × 2 = 16
For x = 3
y = 8 × 3 = 24
For x = 5
y = 8 × 5 = 40
The table :
x __ 0 __ 1 __ 2 __ 3 __ 4 ___ 5
y __ 0 __ 8 _ 16 __24 _ 32 __ 40
B.)
The relationship between amount earned and number of hours is proportional as values obey the proportionality relationship shown in A.
C.)
The point which represents the constant of proportionality should have a y value of 8 :
Hence, the point is 1.
D.)
The y/x ratio :
Point 0 :
y/x = 0/0 = 0
Point 1 :
y/x = 8/1 = 8
Point 2 :
y/x = 16 /2 = 8
Point 3 :
y/x = 24/3 = 8
Point 4 :
y/x = 32 / 4 = 8
Point 5 :
y/x = 40 / 5 = 8

The product of 7 and a number subtracted from 49 is 21. How do I write that as an equation?
Answer:
7x-49=21
Step-by-step explanation:
A = [tex]\frac{1}{2}[/tex]h(B + b) Solve for B.
(area of a trapezoid)
A = 1/2h(B+b)
Multiply both sides by 2:
2A = h(B+b)
Divide both sides by h:
2A/h = (B+b)
Subtract b from both sides:
2A/h - b = B
Switch the equation so B is on the left side:
B = 2A/h - b
Step-by-step explanation:
[tex]a = \frac{1}{2} h( \beta + b) \\ 2a = h( \beta + b) \\ \frac{2a}{h} = \beta + b \\ \frac{2a}{h} - b = \beta \\ thank \: you[/tex]

RS = 3x - 16, ST = 4x - 8, RT = 60
Answer:
RS = 20
ST = 40
Step-by-step explanation:
R____S____T
RS + ST = RT
3x - 16 + 4x - 8 = 60
3x + 4x - 16 - 8 = 60
7x - 24 = 60
+24 +24
--------------------------------
7x = 84
/7 /7
---------------------------------
x = 12
Let's use what we got for x to find the length of ST and RS
ST = 4x - 8
= 4(12) - 8
= 48 - 8
ST = 40
RS = 3x - 16
= 3(12) - 16
= 36 - 16
RS = 20
so, RS = 20, ST = 40, and RT = 60
Answer:
RS = 20 and ST = 40
Step-by-step explanation:
x = 12
use this to find RS and ST by plugging in to their equations.

because from the graph x = 2pie

The function whose graph is given by; cos (1/2 x )
What is graph?A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For example, if the graph of a function is rising upwards after a certain value of x, the function must be having increasingly output for inputs greater than that value of x.
If the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
The function that we are given graphed has the point (0,1), this means whichever function f(x) it represents f(0) = 1.
Now, only the cosine function has the property that cos(π) = -1, thus
y = cos (x/2)
because from the graph x = 2π
The function whose graph is given by; cos (1/2 x )

The value of 0.16 x 42.1 x 8.73 after multiplying is 58.80528.
Given,
(0.16)(42.1)(8.73)
We need to multiply the decimal numbers.
How do we multiply decimal numbers?When we multiply decimal numbers the decimal point should be placed after the number of counts from the right side.
The number of counts is the sum of the counts of numbers before the decimal point of each decimal number from the right side.
Example:
1.23 x 134.5
Here,
In 1.23 there are two numbers before the decimal point.
In 134.5 there is one number before the decimal point.
So the count = 2 + 1 = 3
So,
There should be three numbers after the decimal point in 1.23. x 134.5.
1.23. x 134.5 = 165.435
Find 0.16 x 42.1 x 8.73 by multiplying.
We see that,
There are two numbers after the decimal point in 0.16
There are one numbers after the decimal point in 42.1
There are two numbers after the decimal point in 8.73
So,
2 + 1 + 2 = 5 numbers
There should be 5 numbers after the decimal point in 0.16 x 42.1 x 8.73
Now,
0.16 x 42.1 x 8.73 = 58.80528.
Thus the value of 0.16 x 42.1 x 8.73 is 58.80528.
